The process of carrying in and installing the fixed-side drive unit for the upper floor to install the fixed-side drive unit for the upper floor, which is the floor side of the floor parking portion, and the current position of each vertical column before installing the fixed-side drive unit for the upper floor. The step of adding each vertical column to increase the upper end so as to be higher than the fixed side drive unit for the upper floor, and the tray carried into the parking portion on the upper floor through the lift opening on the fixed side for the upper floor. The process of arranging the tray so as to be movable on the drive unit and using the tray as a work scaffold, and then carrying in the uppermost vertical column unit of the vertical column from the lift opening and combining it on the already expanded part. Then, an expansion process of completing the four vertical pillars having a predetermined height is performed.

According to the installation method of such a parking device, if four vertical columns are divided under predetermined conditions and they are added while being carried in at an appropriate timing, sufficient carry-in is performed without narrowing the space from the lift opening. Space can be secured, without constructing a scaffolding for large-scale work, and an efficient installation process procedure can be established so that the installation work time can be shortened as a whole. Become.

Further, the present invention is the lowermost vertical column unit in a state where the upper end of each vertical column at the present time in the carry-in and installation step of the lift drive system in the pit is limited to the height below the floor surface in the lower floor parking portion. After the carry-in installation step of the lift drive system in the pit, the upper end of each of the vertical columns at the present time becomes higher than the floor surface of the lower floor parking portion prior to the carry-in of the tray into the lower floor parking portion. The feature is that the expansion process of each vertical column to be expanded is performed.

According to such a parking device installation method, the upper end of each vertical column in the loading and installation process of the lift drive system in the pit is limited at the present time to reduce the size and weight of the lowermost vertical column unit, and then the lower floor parking is performed. The tray can be used as a relatively simple scaffold by adding it with an additional vertical column unit prior to bringing the tray into the part.

The parked vehicle 3 boarded from the doorway 2 of the parking device building 1 is mounted on a tray 5 which is arranged so as to substantially cover the lift opening 4 and is on standby, and the lift device 6 is driven after the driver gets off. , The lift device 6 moves up and down to the parking space. The lift device 6 includes vertical columns 7A, 7B, 8A, 8B, which are arranged substantially vertically extending at substantially four corners of the lift opening 4 and are composed of four guide rails and strength members, and the vertical columns 7A to 8B. An elevating portion 9 that can move in the vertical direction along the above, an elevating drive device 10 used to drive the elevating portion 9, and a pair of speed reducers 11A and 11B connected to the elevating drive device 10 vertically. It has rotating shafts 12A, 12B and the like that are rotatably supported between the columns 7A and 8A and between the vertical columns 7B and 8B and rotated via the speed reducers 11A and 11B.

The parking space for storing the parked vehicle 3 mounted on the tray 5 is a lower floor parking portion 15 of the parking space in which a plurality of fixed side drive units 14 for the lower floor are fixed to the floor side, and a plurality of fixed for the upper floor. It has an upper floor parking portion 17 of a parking space in which the side drive unit 16 is fixed to the floor side. A plurality of frame pillars 19 having fixed lower ends are established on a plurality of bases 18 fixed to the floor at the outer periphery of the lower floor fixed side drive unit 14 arranged in the lower floor parking portion 15, and each frame. A fixed-side drive unit 16 for the upper floor is supported at the upper end of the pillar 19. Although detailed illustration is omitted, the lower floor fixed side drive unit 14 and the upper floor fixed side drive unit 16 arranged on the floor of the lower floor parking portion 15 and the upper floor parking portion 17 face the tray 5. A well-known direction-changing drive mechanism is configured in the portion to be driven so that the tray 5 can be moved to an arbitrary front-back / left-right position by driving the direction-changing drive mechanism based on a command from the control panel. It is configured in.

In the parking device building 1, a pit 20 is dug in the vertical direction to form the lift device 6, and a lift opening 4 is formed in the upper part of the pit 20. In the used state after assembly, the lift opening 4 is closed by the configuration of a turntable, a tray 5, and the like, and the parked vehicle 3 boarded from the doorway 2 of the parking device building 1 is parked only by the elevating part 9 of the lift device 6. It is configured to be able to move to space. However, during the installation work, the turntable and the tray 5 are not yet arranged in the lift opening, and various parts constituting the parking device can be carried in only from the lift opening 4 existing above the lift device 6. It is possible.

Next, a method of installing the parking device according to the embodiment of the present invention will be described.

FIG. 3 is a flowchart showing a method of installing the parking device.
In step S1, an installation preparation step is carried out, which is a preparation for suspending various parts constituting the parking device from the lift opening existing in the upper part of the lift device 6. In step S2, the lower floor fixed side drive unit 14 to be installed in the lower floor parking portion 15 is carried in from the lift opening 4, and then fixed to the floor surface of the lower floor parking portion 15 for each lower floor. The fixed side drive unit for the lower floor where the side drive unit 14 is installed is carried in and installed.

In step S3, after the fixed side drive unit 14 for the lower floor is carried in, the upper ends of the vertical columns 7A to 8B that are carried in through the lift opening 4 and installed in the pit 20 are set at a height below the floor surface in the lower floor parking portion 15. The carry-in and installation process of the lift drive system in the pit including the lowermost vertical column unit in the restricted state is performed.

In step S4, prior to the loading of the tray, an expansion step of each vertical column is performed in which the upper ends of the vertical columns 7A to 8B are expanded so as to be higher than the floor surface of the lower floor parking portion 15.

In step S5, the tray carried into the lower floor parking portion 15 through the lift opening 4 is movably arranged on the lower floor fixed side drive unit 14, and the tray is used as a work scaffold. In the following step S6, the assembly lifting device is carried onto the tray through the lift opening 4, and then the upper floor fixed side drive unit 16 on the floor side of the upper floor parking portion 17 is used by using the assembly lifting device. The fixed side drive unit for the upper floor is carried in and installed.

In step S7, before the installation of the upper floor fixed side drive unit 16 in step S6, the upper ends of the vertical columns 7A to 8B are added so as to be at a height equal to or higher than the upper floor fixed side drive unit 16. Perform the expansion process.

In step S8, the tray carried into the parking portion 17 on the upper floor through the lift opening 4 is movably arranged on the fixed side drive unit 16 for the upper floor, and the tray is used as a work scaffold. Further, in step S9, after that, the uppermost vertical column units of the vertical columns 7A to 8B are carried in from the lift opening 4 and joined onto the already expanded portion, and the four vertical columns having a predetermined height are connected. An expansion process is performed to complete 7A to 8B.

As can be seen from this flowchart, the lift device 6 has four vertical columns 7A to 8B dispersedly arranged at the four corners of the lift opening 4, and each of the vertical columns 7A to 8B has a plurality of vertical columns 7A to 8B in the axial direction. It is divided into. Here, it is described as being divided into four parts: the lowermost vertical column unit, the second vertical column unit, the third vertical column unit, and the uppermost vertical column unit. As each process progresses, the lower vertical column unit, the second vertical column unit, the third vertical column unit, and the uppermost vertical column unit are sequentially joined by welding, and the lift device 6 is installed by the time the installation work is completed. The vertical columns 7A to 8B of the above are completed to a predetermined length.

As will be clarified by the following detailed explanation, if the four vertical columns 7A to 8B are configured with a predetermined length from the beginning, they are configured in the pit through the lift opening, and in the lower floor parking part and the upper floor parking part. It narrows the space when carrying in the elements. However, as described above, if the four vertical columns 7A to 8B are divided under predetermined conditions and they are added while being carried in at an appropriate timing, a sufficient carrying-in space can be obtained without narrowing the space from the lift opening 4. It can be secured, and without constructing a scaffolding for large-scale work, an efficient installation process procedure can be established, and the installation work time can be shortened as a whole.

Next, a specific installation method will be described according to each procedure.

In step S1 shown in FIG. 3, an installation preparation step for suspending various parts constituting the parking device from the lift opening 4 existing in the upper part of the lift device 6 is carried out.

As shown in FIG. 1, a building cross beam 21 and the like are present on the ceiling of the parking device building 1 located above the lift opening 4 existing at the upper part of the lift device 6. Therefore, between the cross beams 21 of the building, a work rail 22 extending in the approach direction of the parked vehicle 3 boarded from the entrance 2 of the parking device building 1 is firmly supported and fixed, and an electric chain capable of traveling along the work rail 22 is firmly supported and fixed. The block device 23 is installed. The electric chain block device 23 is not limited to the arrangement and configuration of this embodiment, and may have other configurations, or a plurality of cooperating units may be installed.

In step S2 shown in FIG. 3, the lower floor fixed side drive unit 14 to be installed in the lower floor parking portion 15 is carried in from the lift opening 4, and then on the floor surface of the lower floor parking portion 15. The lower floor fixed side drive unit carry-in installation step for installing each lower floor fixed side drive unit 14 is performed. Here, before assembling the drive system in the pit 20 of the lift device 6, the carry-in / installation step of the fixed-side drive unit 14 for the lower floor is carried out.

4 and 5 are perspective views of the vicinity of the pit showing the loading work state and the installation work state of the fixed side drive unit 14 for the lower floor.

In the completed parking device shown in FIGS. 1 and 2, a plurality of lower floor fixed side drive unit 14s are attached to the floor side of the lower floor parking portion 15, and any lower floor fixed side drive unit 14 is provided. The tray 3 is desired by repeating the circulation process of moving the tray 3 located on the unit 14 or the tray 3 on which the parked vehicle is mounted to the adjacent fixed side drive unit 14 side for the lower floor. It constitutes a drive device that circulates and moves to a position.

Therefore, the size is substantially corresponding to the lift opening 4. When the carry-in work of the lower floor fixed side drive unit 14 is performed after the entire lift device 6 is assembled, the assembled lift devices 6, particularly the vertical columns 7A to 8B, are formed below the lift opening 4. The space becomes narrow and the loading work becomes very troublesome. However, since the lower floor fixed side drive unit 14 is carried in before the lift device 6 is assembled, the lower floor fixed side drive unit 14 is efficiently lowered while fully utilizing the lift opening 4. You can move to the floor parking area 15.

As shown in FIG. 4, the lower floor fixed side drive unit 14 includes a drive motor 25, a feed roller 26 driven by the drive motor 25, a pair of longitudinal rails 73, and a pair of longitudinal rails 73 in a substantially quadrangular outer frame frame 24. The width direction rail 74, the base plate 75, and the like are incorporated and carried in in a pre-assembled state. The operator carries in the fixed-side drive unit 14 for the lower floor one by one from the doorway 2 of the parking device building 1 using a dolly or the like, and temporarily places it in the vicinity of the lift opening 4.

After that, the operator slings the fixed-side drive unit 14 for the lower floor in the temporarily placed state using the electric chain block device 23, and then opens the lift while operating the electric chain block device 23 as shown in FIG. The fixed side drive unit 14 for the lower floor is hung down through the unit 4. Other work vehicles in the lower floor parking portion 15 use the interlaced rope 27 connected to the lower floor fixed side drive unit 14 to move the lower floor fixed side drive unit 14 above the lower floor parking portion 15. The electric chain block device 23 is disconnected after being mounted on the trolley 28 already arranged on the lower floor parking portion 15.

After that, the operator uses the trolley 28 to move the fixed-side drive unit 14 for the lower floor to a predetermined position of the parking portion 15 on the lower floor. When the predetermined position is reached, the operator installs a plurality of tripod chain block devices 29 on the floor surface at that position as shown in FIG. 5, and uses each tripod chain block device 29 to drive the fixed side for the lower floor. The trolley 28 is removed while the unit unit 14 is temporarily held. Subsequently, while operating each tripod chain block device 29, the operator lowers the lower floor fixed side drive unit 14 onto the receiving member 31 of the mounting base 30 which has been fixed to the floor in advance, and the same unit. Fix to. The operator repeats this work according to the number of the fixed side drive unit 14 for the lower floor.

After that, when the work as step S2 is completed, the operator uses the control panel or the simple operation device for work connected to the control panel to drive the drive motor of the fixed side drive unit 14 for the lower floor. While driving and controlling the 25, the electrical system connection work is continuously performed so that the tray 5 arranged on the fixed side drive unit 14 for the lower floor can be circulated and moved.

For the other work vehicles, at least after the work of bringing the fixed side drive unit 14 for the lower floor into the parking part 15 on the lower floor is completed, as step S3 shown in FIG. 3, the carry-in and installation step of the lift drive system in the pit is performed. Do. In this pit lift drive system, the upper end corresponding to each of the vertical columns 7A to 8B carried in through the lift opening 4 and installed in the pit 20 is limited to the height below the floor surface in the lower floor parking portion 15. Includes the bottom vertical column unit of.

FIG. 6 is a perspective view of the vicinity of the pit showing the loading and installation work state of the lift drive system in the pit.

Since the lift device 6 has a size that cannot be carried in from the lift opening 4 in the assembled state, the size of the doorway 2 and the lift opening 4 of the parking device building 1 should be taken into consideration, and the efficiency should be as described above. In consideration of the specific installation work, the units are divided into a plurality of vertical column units in the height direction, and after being carried in, they are assembled in the pit 20.

As shown in FIG. 6, the lift drive system in the pit carried in in step S3 is divided so as to be distributed and arranged on both sides in the longitudinal direction of the tray, and the lowermost vertical column unit having the rotating shafts 32A and 32B, respectively. The elevating drive device 10 to be arranged between the 33A and 33B and the lowermost vertical column units 33A and 33B, and the rotational driving force from the elevating drive device 10 are transmitted to the lowermost vertical column units 33A and 33B, respectively. It has speed reducers 11A, 11B, etc., which are to be used, and each of them is hung separately to carry in and install the lift drive system in the pit to be installed in the pit 20.

The lowermost vertical column units 33A are arranged below the two lowermost vertical columns 34A and 35A and the lowermost vertical columns 34A and 35A that are arranged so as to face each other on one side in the longitudinal direction of the tray 5. A pair of frame portions 36A to be installed on the floor surface of the pit 20, a rotating shaft 32A rotatably supported between the frame portions 36A, and a pair of sprocket 34A coupled to the rotating shaft 32A. It has a driving force transmission connecting portion 38A that is configured in one frame portion 35A of the rotating shaft 32A and is connected to the speed reducer 11A, and a lower connecting cross beam 39A that connects the facing portions of the lowermost vertical columns 34A and 35A. It is composed of.

The same applies to the lowermost vertical column unit 33B, which is located below the two lowermost vertical columns 34B and 35B and the lowermost vertical columns 34B and 35B which are arranged so as to face each other on one side in the longitudinal direction of the tray. A pair of frame portions 36B that are arranged and installed on the floor surface of the pit 20, a rotating shaft 32B rotatably supported between the frame portions 36B, and a pair of sprocket 34B coupled to the rotating shaft 32B. And the lower connecting cross beam 39B, which is formed by one frame portion 35B of the rotating shaft 32B and is connected to the speed reducer 11B, and the facing portions of the lowermost vertical columns 34B and 35B are connected. It is configured to have.

In step S3, the worker first wraps a safety fence 40 around the pit 20 which is relatively simple compared to the scaffolding, and the other workers put the lowermost vertical column unit 33A, which will be installed in the pit 20. The 33B, the elevating drive device 10, the speed reducers 11A, 11B and the like are carried in from the doorway 2 of the parking device building 1 and temporarily placed in the vicinity of the lift opening 4.

Using the electric chain block device 23 shown in FIG. 6, the operator sequentially slings the lowermost vertical column units 33A and 33B in the temporarily placed state, the elevating drive device 10, the speed reducers 11A and 11B, and the like for each division unit. The electric chain block device 23 is hung in the pit 20 while being operated, installed at a predetermined floor surface position, and then separated from the electric chain block device 23.

For example, the operator arranges the lowermost vertical column unit 33A on one side in the longitudinal direction in the pit 20, arranges the lowermost vertical column unit 33B on the other side in the longitudinal direction in the pit 20, and arranges the lowermost vertical column unit 33B in the width direction in the pit 20. The elevating drive device 10 and the speed reducers 11A and 11B are arranged on one side. After that, the operator installs and fixes the lowermost vertical column units 33A and 33B, the elevating drive device 10 and the speed reducers 11A and 11B at predetermined positions while positioning on the bottom surface of the pit 20, and performs the connection work.

The installation work of the lower floor fixed side drive unit 14 in step S2 described above can be performed in parallel until the carry-in installation step of the lift drive system in the pit shown in step S3 is completed. At this time, the height dimension of the lowermost vertical column units 33A and 33B is such that it fits in the pit 20, and the work in the pit 20 and the work in the lower floor parking portion 15 can be performed by installing a simple safety fence 40. We are trying to be able to do it safely in parallel.

In particular, since the lower floor fixed side drive unit 14 is performed at the lower floor parking portion 15 prior to the carry-in and installation work of the lift drive system in the pit in the pit 20, the work in the pit 20 is performed. If the work in the pit 20 is completed while the work in the lower floor parking portion 15 is performed in parallel, the next carry-in work becomes possible and the carry-in work using the electric chain block device 23 can be efficiently performed. it can.

Next, in step S4, prior to the loading of the tray, the upper ends of the vertical columns 34A to 35B in the lowermost vertical column units 33A and 33B are added so as to be higher than the floor surface of the lower floor parking portion 15. Perform the pillar expansion process.

FIG. 7 is a perspective view of the vicinity of the pit showing the working state of the vertical column expansion process.

After temporarily placing the lowermost vertical column units 33A and 33B in the vicinity of the lift opening 4, the operator uses the electric chain block device 23 as shown in FIG. 7 to temporarily place the lowermost vertical column units 33A and 33B. The second-stage additional vertical column units 41A and 41B, which will be welded to the upper part, will be carried in.
The additional vertical column unit 41A is connected between the second-stage vertical columns 42A and 43A to be connected to the lowermost vertical columns 34A and 35A of the lowermost-stage vertical column unit 33A and the second-stage vertical columns 42A and 43A. It has a pair of second-stage connecting cross beams 44A and the like. The same applies to the additional vertical column unit 41B, between the second vertical columns 42B and 43B and the second vertical columns 42B and 43B to be connected to the lowermost vertical columns 34B and 35B of the lowermost vertical column unit 33B. It has a pair of cross beams 44B for connecting the second stage and the like.

The operator joins the upper ends of the lowermost vertical columns 34A and 35A in the lowermost vertical column unit 33A and the lower ends of the second vertical columns 42A and 43A in the additional vertical column unit 41A by welding, and similarly. The upper ends of the lowermost vertical columns 34B and 35B in the lowermost vertical column unit 33B and the lower ends of the second vertical columns 42B and 43B in the additional vertical column unit 41B are joined by welding.

At this time, the height dimension of the upper ends of the second-stage vertical columns 42A and 43A in the additional vertical column unit 41A and the upper ends of the second-stage vertical columns 42B and 43B in the additional vertical column unit 41B is upward from the pit 20. It protrudes by a predetermined distance. This predetermined distance means that the tray carried into the lower floor parking portion 15 through the lift opening 4 is movably arranged on the lower floor fixed side drive unit 14 in step S5 described later, and the tray is used as a work scaffold. After performing the process, it is possible to perform the expansion work of the next expansion column units 58A and 58B shown in FIG. 15 without disassembling the work scaffolding by the tray. Moreover, since the protrusion length is limited as a predetermined distance, a space that provides a sufficient carry-in space below the lift space portion 4 when a tray 5 or the like having a relatively large shape is subsequently carried in from the lift opening 4. The part can be secured.

After that, although not shown, a weight for balancing with the elevating portion 9 of the lift device 6 is carried in in the same manner, and temporarily placed on the back side of the lowermost vertical column units 33A and 33B and the additional vertical column units 41A and 41B. Place.

After the vertical column expansion process for welding the additional column units 41A and 41B is completed, the safety fence 40 shown in FIG. 7 is removed, and the additional column units 41A and 41B protruding from the pit 20 are removed as shown in FIG. Simple safety fences 45A and 45B are installed so as to shield them.

Next, as step S5 shown in FIG. 3, a step of arranging the tray carried into the lower floor parking portion 15 through the lift opening 4 so as to be movable on the lower floor fixed side drive unit 14 and using the tray as a work scaffold. I do. The step of using this tray as a work scaffold involves a step of covering the upper surface of the pit 20 as the first step step S5A and a step of loading and installing the tray as the second step step S5B.

FIG. 8 is a perspective view of the vicinity of the pit showing the loading and unloading work state of the elevating portion 9.

By the time this work is started, the lower floor fixed side drive unit units 14A and 14B have already been arranged on both sides in the width direction except directly above the pit 20, and are fixed to the floor surface of the lower floor parking portion 15. It is fixed to the receiving member 31 of the mounting base 30. Here, the lower floor fixed side drive unit 14B is fixed to the floor surface formed on the left side of the pit 20 shown in FIG. 1, that is, the floor surface formed at the same level as the lower floor parking portion 15. Has been done.

If there is no space on the left side of FIG. 1 for arranging the lower floor fixed side drive unit 14B, the lower floor fixed side drive unit 14B can be omitted, as can be seen from the explanation described later. Since the worker rarely uses the floor side, there is no safety problem. Further, depending on the size of the lower floor parking portion 15, after the assembly as the parking device is completed, the lower floor fixed side drive unit 14B can be left as it is and used as a storage space for the parked vehicle, and the installation work. If it is installed exclusively, it can be removed after the assembly as a parking device is completed.

By the way, as a step of covering the upper surface of the pit 20 as step S5A, the operator first, in the vicinity of the lift opening 4 of the doorway 2, the lift stand 46, which is the main component of the lift device 6, and the fixed side for the lower floor. Prepare a lift drive unit 47A and the like having substantially the same configuration as the drive unit 14A and 14B.

Next, the operator suspends the lift stand 46 on the bottom surface of the pit 20 and temporarily places it while passing through the lift opening 4 using the electric chain block device 23, and disconnects the electric chain block device 23.

After that, the operator suspends the lift drive unit 47 as shown in FIG. 8 while passing through the lift opening 4 using the electric chain block device 23, and fixes the lower floors arranged in the vicinity of the pit 20. It is installed so that it is at the same level as the side drive unit 14A and the lower floor fixed side drive unit 14B.

The lift drive unit 47 will eventually form an elevating portion 9 that moves up and down along the vertical columns 7A to 8B together with the lift stand 46. For example, the tray arranged in the lower floor parking portion 15 is fixed for the lower floor. It will be handed over between the side drive unit 14A and the lift drive unit 47.

When the installation of the lift drive unit 47 is completed, the upper surface side of the pit 20 is substantially covered by the lift drive unit 47. Moreover, the lift drive unit 47 and the lower floor fixed side drive units 14A and 14B have almost the same configuration and are arranged at the same level. Therefore, the tray carried in later can be moved between the upper surface of the pit 20 and the lower floor parking portion 15. Further, the lift drive unit 47 has a base plate 75 like the lower floor fixed side drive unit 14 shown in FIG. Then, although the drive motor and the like exist, the operator can use the lift drive unit 47 and the lower floor fixed side drive units 14A and 14B like scaffolding.

As a result, the step of covering the upper surface of the pit 20 as the first step step S5A is completed, and then, as the second step step S5B, the tray is carried in by arranging the tray on the lower floor fixed side drive unit 14A of the elevating portion 9. And perform the installation process.

FIG. 9 is a perspective view of the vicinity of the pit showing the loading and installing state of the tray.

The operator temporarily places a plurality of trays to be installed in the lower floor parking portion 15 in the vicinity of the lift opening 4 as in each of the previous operations. Up to this point, the control panel or the simple operation device for work connected to the control panel is used to drive and control the drive motor 25 of the fixed side drive unit 14A for the lower floor and the lift drive unit 47 on the lower floor. The tray arranged on the fixed side drive unit 14A or the lift drive unit 47 can be circulated and moved.

As shown in FIG. 9, the operator uses the hanging tool 48 attached to the electric chain block device 23 to carry in the trays 5A and 5B in order to arrange the trays 5A and 5B in the lower floor parking portion 15. First, the tray 5A is lifted and carried in by the electric chain block device 23 prior to the tray 5B shown in FIG. 9, and then the lift drive unit 47 or the lower floor fixed side drive unit 14A located below the tray 5A is lifted and carried in. , 14B is driven by a simple operation device for work, and the position of the tray 5A is changed from directly above the pit 20 to another position. Next, as shown in FIG. 9, the operator suspends and carries in the next tray 5B using the hanging tool 48 attached to the electric chain block device 23, and carries it into the lift drive unit 47 directly above the pit 20. The tray 5B is mounted.

When the second tray 5B is installed, a work scaffold for the worker is formed by the trays 5A and 5B juxtaposed in the vicinity directly above the pit 20. That is, a relatively large scaffolding for work can be obtained in the vicinity of the upper part of the pit 20 by the trays 5A and 5B which are the components for the main installation.

The carrying-in work of the remaining trays may be performed after that in the same manner as the trays 5A and 5B, and then the installation work thereof may be performed, but for the time being, only the two trays 5A and the tray 5B are carried in and described later. It may be performed at an appropriate timing until the work shown in FIG.

Next, in step S6 shown in FIG. 1, the assembly lifting device is carried onto the tray through the lift opening 4, and then the assembly lifting device is used to be on the floor side of the upper floor parking portion 17. The upper floor fixed side drive unit 16 is attached. The upper floor fixed side drive unit is carried in and installed.

Here, step S6 is a step of carrying the assembly lifting device onto the tray 5B as step S6A, and a step of establishing a frame pillar on the floor side of the lower floor parking portion 15 using the assembly lifting device as step S6B. The steps S6C will be described separately for the step S6C of carrying in and installing the upper floor fixed side drive unit 16 to which the upper floor fixed side drive unit 16 on the floor side of the upper floor parking portion 17 is attached by using the assembly lifting device.

FIG. 10 is a perspective view of the vicinity of the pit showing the loading state of the lifting device for assembly.

First, in step S6A, the operator suspends the assembly lifting device 51 temporarily placed in the vicinity of the lift opening 4 by the electric chain block device 23 as in the past, and is on the tray 5B of the lower floor parking portion 15. To be installed in. Here, the configuration of the assembly lifting device 51 will be described.

FIG. 11 is a perspective view showing an assembly lifting device 51.

The assembly lifting device 51 is for use in subsequent work processes, and is configured on a base 76 at a fixed frame portion 52 composed of a frame body and at four corners of the fixed frame portion 52, respectively. A plurality of holding arm portions 53 configured to hold the fixed side drive unit for the upper floor, which will be described later, when extended to the upper part, and both sides of the fixed frame portion 52, that is, the tray 5B as shown in FIG. Two foldable crane devices 54 and 55 mounted so as to be positioned in the longitudinal direction of the above, and a fixed side drive unit for the upper floor, which will be described later, mounted on the upper part of the fixed frame 52. It is configured to have a lifting device 56 such as a push-up type lifting device configured so that it can be held.

As shown in FIG. 10, the operator suspends the assembly lifting device 51 in which the crane devices 54 and 55 are folded on the tray 5B of the lower floor parking portion 15 by the electric chain block device 23. At this time, since the worker who carries in and assembles the assembly lifting device 51 can perform the process on the main trays 5A and 5B as shown in FIG. 10, a temporary work table is installed. It can be done easily without any need. Further, since the movable side trays 5A and 5B for the main installation have a quadrangular plate shape, the operator can safely perform the work as if he / she were on the floor. After that, the operator performs a step of establishing a frame pillar on the floor side of the lower floor parking portion 15 by using the assembly lifting device 51 carried in as step S6B.

FIG. 12 is a perspective view of the vicinity of the pit showing the loading state of the frame pillars.

After lowering the assembly lifting device 51 onto the main trays 5A and 5B as shown in FIG. 12, the operator uses the electric chain block device 23 to form the upper floor parking portion 17. A plurality of frame pillars 19 to be used in the above are carried in, and each frame pillar 19 is lowered onto the tray 5A. At this time, the operator uses the above-mentioned simple operation device for work to replace the tray 5B and the tray 5A located directly above the pit 20, or uses the crane devices 54 and 55 in the assembly lifting device 51. Then, a plurality of frame columns 19 are placed on the tray 5A and temporarily placed. After that, the operator performs the installation step of the frame pillar 19 while using the assembly lifting device 51 at the lower floor parking portion 15.

13 and 14 are perspective views of the assembly lifting device 51 showing the installation work start state and the installation work state of the frame pillar 19.

In the lower floor parking portion 15, as shown in FIG. 13, the operator can operate the tray 5B on which the assembly lifting device 51 is mounted and the tray 5A on which each frame pillar 19 is mounted for the above-mentioned simple operation for work. The device is used to move it to a suitable installation position in the lower floor parking section 15. After that, as shown in FIG. 14, the operator extends the crane devices 54 and 55 of the assembly lifting device 51, and while lifting the frame pillar 19 by the crane devices 54 and 55, the lower floor fixed side drive unit 14 The lower ends of the frame columns 19 are fixed to the mounting bases 18 fixed near the four corners.

By repeating this work, frame pillars 19 are established near the four corners of all the fixed-side drive unit 14s for the lower floors arranged in the parking lot portion 15 on the lower floors. During step S6, that is, when the fixing work of the frame pillar 19 shown in FIG. 14 is performed at the lower floor parking portion 15 away from the vicinity of the pit 20, or when the assembly lifting device 51 is used as step S6C. Before the step of carrying in and installing the upper floor fixed side drive unit 16 for attaching the upper floor fixed side drive unit 16 on the floor side of the upper floor parking portion 17, step S7 described below is performed.

In step S7 shown in FIG. 3, the third-stage additional vertical column unit is suspended from the lift opening 4, and the third-stage additional vertical column is hung from the additional vertical column units 41A and 41B already installed in the pit 20. Weld the unit and perform the vertical column expansion process.

FIG. 15 is a perspective view of the vicinity of the pit showing a state after the vertical column expansion work.

In step S7, which is performed in parallel with step S6 described above, the third-stage expansion column unit 58A, which will be coupled to the upper portions of the expansion column units 41A and 41B, respectively, by using the electric chain block device 23, The carry-in work of 58B is carried out.

The third-stage additional vertical column unit 58A is the third-stage vertical column 59A, 60A and the third-stage vertical column 59A, 60A to be connected to the second-stage vertical columns 42A, 43A of the additional vertical column unit 41A shown in FIG. It has a third-stage connecting cross beam 61A that connects the vertical columns 59A and 60A. The same applies to the third-stage vertical column unit 58B, and the third-stage vertical columns 59B and 60B and the third-stage vertical columns 59B, which will be connected to the second-stage vertical columns 42B and 43B of the additional vertical column unit 41B, It has a third-stage connecting cross beam 61B and the like that are connected between 60B.

Next, the operator joins the upper ends of the second-stage vertical columns 42A and 43A and the lower ends of the third-stage vertical columns 59A and 60A by welding, and similarly, the second-stage vertical columns 42B and 43B. The upper end and the lower ends of the third vertical columns 59B and 60B are joined by welding. At this time, the upper ends of the third-stage vertical columns 59A and 60A and the upper ends of the third-stage vertical columns 59B and 60B are formed by the upper-floor fixed-side drive unit 16 in the upper-floor parking portion 17. The length is preset so that it is located slightly above the floor surface.

In the following step S6C, the upper floor fixed side drive unit 16 is suspended from the lift opening 4 and received by the assembly lifting device 51, and then the upper floor fixed side drive unit 16 is moved to four frames while moving the tray 5B. The carry-in and installation process of the fixed side drive unit for the upper floor to be fixed on the pillar 19 is performed. The upper floor fixed side drive unit 16 has the same configuration as the lower floor fixed side drive unit 14 described with reference to FIG.

First, the operator carries in the fixed-side drive unit 16 for the upper floor from the doorway 3 of the parking device building 1 and temporarily places it in the vicinity of the lift opening 4. After that, as in the case of the previous work process, the worker slings the electric chain block device 23 on one of the fixed-side drive unit 16 for the upper floor in the temporarily placed state.

On the other hand, another worker folded the arms of the crane devices 54 and 55 of the assembly lifting device 51 mounted on the tray 5B from the extended state shown in FIG. 14 as shown in FIG. After returning to the state, the tray 5B is moved to a position directly above the pit 20 while the assembly lifting device 51 is mounted by using the above-mentioned simple operation device for work. After that, the operator extends the four holding arm portions 53 formed at the four corners of the fixed frame portion 52 shown in FIG. 14 upward, and the lifting device 56 configured on the upper part of the assembling lifting device 51. Is lifted upward so that the fixed-side drive unit 16 for the upper floor, which is subsequently carried in, can be received at a predetermined height. At this time, the fixed-side drive unit 16 for the upper floor is held at a height at which the tray 5B can be easily horizontally moved by the parking portion 15 on the lower floor without contacting the frame pillar 19.

Next, the operator suspends the fixed-side drive unit 16 for the upper floor on the holding arm 53 and the lifting device 56 of the assembling lifting device 51 while operating the electric chain block device 23, and then suspends the electric chain block. The device 23 is disconnected. Next, a moving step is performed in which the tray 5B on which the assembly lifting device 51 and the fixed-side drive unit 16 for the upper floor are mounted is moved by the parking portion 15 on the lower floor.

16 and 17 are perspective views showing a moving state of the tray 5B in the lower floor parking portion 15 and a working state of fixing the tray 5B on the frame pillar.

In the state shown in FIG. 16, the operator moves the tray 5B from the position directly above the pit 20 to another position of the lower floor parking portion 15 by using the above-mentioned simple operation device for work. At this time, since the upper floor fixed side drive unit 16 lifted upward by the four holding arms 53 and the lifting device 56 is held at a predetermined height, it is moved up as shown in FIG. It is held at a height that does not come into contact with the upper end of the frame pillar 19 that has already been erected to form the floor parking portion 17.
When the tray 5B reaches a predetermined position, the operator lowers each holding arm 53 of the assembly lifting device 51 to return it to the stored state as shown in FIG. 17, and the upper floor fixed side drive unit 16 Is supported only by the lifting device 56. After that, the operator operates the lifting device 56 to slowly lower the upper floor fixed side drive unit 16 and hold it at a position corresponding to the upper fixed portion 62 of the frame pillar 19, and in this state, the two are combined. To do. After that, the worker repeats the work described with reference to FIGS. 15 to 17 according to the number of other fixed-side drive unit 16 for the upper floor to be arranged in the upper floor parking portion 17 of the parking space.

After that, the operator uses the control panel or the simple operation device connected to the control panel by this point, as in the case of the fixed side drive unit 14 for the lower floor arranged in the lower floor parking portion 15. Then, while driving and controlling the drive motor of the upper floor fixed side drive unit 16, the tray arranged thereafter on the upper floor fixed side drive unit 16 can be circulated and moved.

As described above, the assembling lifting device 51 is configured as an integrated type having the crane devices 54 and 55 and the lifting device 56, and is mounted on the tray 5B for use. Therefore, the tray 5B is pitted. A plurality of fixed-side drive unit 16s for the upper floor can be fixed to the frame pillar 19 to form the upper floor parking portion 17 of the parking space while moving between the directly above the 20 and the lower floor parking portion 15. Moreover, during the assembly process of the upper floor parking portion 17 shown in step S6, the assembly lifting device 51 is not disassembled and is not replaced with another work table, so that the work is simple and can be performed in a short time. be able to.

Next, in step S8 shown in FIG. 3, a step of arranging the tray carried into the upper floor parking portion 17 through the lift opening 4 so as to be movable on the upper floor fixed side drive unit 16 and using the tray as a work scaffold is performed. Do.

FIG. 18 is a perspective view of the vicinity of the pit showing a working state prior to loading the tray.

While operating the electric chain block device 23, the operator lifts the used assembly lifting device 51 and collects it from the lift opening 4. After that, the operator changes the position of the lift drive unit 47 used in FIG. First, the operator lifts the lift drive unit 47 from the lower floor parking portion 15 directly above the pit 20 while operating the electric chain block device 23, and is already installed on both sides in the width direction in the upper floor parking portion 17. The fixed side drive units 16A and 16B for the upper floors are fixed so that they are at almost the same level.

When the movement of the lift drive unit 47 is completed, the space between the upper floor fixed side drive units 16A and 16B is almost covered by the lift drive unit 47. Moreover, since the lift drive unit 47 and the upper floor fixed side drive unit units 16A and 16B are arranged at the same level, the tray that is later carried into the upper floor parking portion 17 is the lift drive unit 47. It is possible to move between the fixed side drive units 16A and 16B for the upper floor. Further, as described above, although there are drive motors and the like on the upper surface side of the lift drive unit 47 and the upper floor fixed side drive unit units 16A and 16B, the operator can use them like scaffolding. It becomes.

Next, the operator makes use of the structural features of the third-stage additional vertical column units 58A and 58B protruding above the lift drive unit 47, and takes advantage of the structural features of the third-stage vertical columns 59A and 59B and the third-stage vertical columns 59A and 59B. The main rope 63 is fixed between the vertical columns 60A and 60B, respectively. Further, after the safety rope 64 of the work vehicle is slidably tied to the main rope 63, the subsequent work on the fixed side drive unit 16 for the upper floor, that is, the loading and installation of the tray to the parking portion 17 on the upper floor. Do the work.

As described above, the upper ends of the third-stage vertical columns 59A to 60B in the third-stage additional vertical column units 58A and 58B are slightly smaller than the upper-floor fixed-side drive unit units 16A and 16B constituting the upper-floor parking portion 17. It extends upward. Therefore, the main rope 63 can be fixed by utilizing the third-stage additional vertical column units 58A and 58B that protrude from the fixed-side drive unit units 16A and 16B for the upper floor. At this time, there is no need to build a scaffold for complicated work or add a new strong structure to stretch the main rope 63, so the work is easy and the time required for the entire installation work is shortened. can do.

FIG. 19 is a perspective view of the vicinity of the pit showing the loading and installing state of the tray.

The operator temporarily places a plurality of trays to be installed in the upper floor parking portion 17 in the vicinity of the lift opening 4 as in each work so far. By this point, the control panel or the simple operation device for work connected to the control panel is used to drive the drive motors 25 of the upper floor fixed side drive unit 16A and 16B while driving the upper floor fixed side drive. The trays to be arranged on the unit 16A can be circulated and moved.

As shown in FIG. 19, the operator uses the hanging tool 48 attached to the electric chain block device 23 to carry in the trays 5L and 5M in order to arrange the trays 5L and 5M in the parking portion 17 on the upper floor. First, the tray 5L is lifted and carried in by the electric chain block device 23 prior to the tray 5M shown in FIG. 19, and then the lift located at the lower part of the tray 5L using the above-mentioned simple operation device for work. The drive motor of the drive unit 47 is driven, and the tray 5L is moved from directly above the pit 20 onto the fixed-side drive unit 16A for the upper floor.

Next, while using the tray 5L as a scaffolding for work, the worker hangs and carries in the next tray 5M by using the hanging tool 48 attached to the electric chain block device 23 again, and the pit 20 is true. The tray 5M is mounted on the lift drive unit 47 arranged above, and then the tray 5M is installed on the lift drive unit 47 and on the upper floor fixed side drive unit 16B.

After that, the worker fixed the stand 66 to the upper end of each frame pillar 19 already established in the vicinity while using the trays 5L and 5M as a scaffold for work, and the main rope 63 between the stands 66. Is replaced, and the safety rope 64 of the work vehicle is slidably tied to the main rope 63, and then the subsequent work is performed.

After taking this safety measure, the operator uses the tray 5L as a scaffolding for work, and also uses the hanging tool 48 attached to the electric chain block device 23 again to suspend and carry in the next tray 5N. Then, the tray 5M is mounted on the lift drive unit 47 arranged directly above the pit 20.

When the three trays 5L to 5N are installed, the work scaffolding for the worker is formed by the trays 5L to 5N juxtaposed in the vicinity directly above the pit 20. That is, a relatively large scaffolding for work can be obtained in the vicinity directly above the pit 20 by the trays 5L to 5N, which are the components for the main installation.

The remaining trays may be carried in in the same manner as the trays 5L to 5N, and then the installation work thereof may be carried out. However, for the time being, only the three trays 5L to 5N are carried in and shown in FIG. 21 described later. It may be performed at an appropriate timing until the work of step S9 shown. These operations complete the process of using the tray as a work scaffold.

Subsequently, in step S9 shown in FIG. 3, the uppermost vertical column unit for completing each of the vertical columns 7A to 8B is carried in from the lift opening 4, and is joined on the already expanded portion to be predetermined. An expansion process is performed to complete the four vertical columns 7A to 8B of height.

20 and 21 are perspective views in the vicinity of the pit showing the initial loading state and the intermediate installation state of the uppermost vertical column unit.

In this step, the operator first temporarily places the uppermost vertical column units 67A and 67B in the vicinity of the lift opening 4, slings the uppermost vertical column units 67B, and then slings the uppermost vertical column units 67B, and then, as shown in FIG. 20, the electric chain. While operating the block device 23, the uppermost vertical column unit 67B is temporarily placed on the tray 5N.

The uppermost vertical column unit 67B is the uppermost vertical column 68B, 69B and the uppermost vertical column 68B, 69B to be connected to the third vertical column 59B, 60B of the third additional vertical column unit 58B shown in FIG. Between the uppermost connecting cross beam 70B connecting the columns 68B and 69B, the pair of sprockets 71B rotatably attached to the uppermost connecting cross beam 70B, and each sprocket 71B and each sprocket 34B shown in FIG. It has a chain 72 and the like that can be hung. The uppermost vertical column unit 67A shown in FIG. 21 has the same configuration, and detailed description thereof will be omitted here.

Next, the operator hangs the chain 72 on the sprocket 71B of the uppermost vertical column unit 67B temporarily placed on the tray 5M to hold the chain 72, and as shown in FIG. 21, the uppermost stage while using the electric chain block device 23. Lift the vertical column unit 67B. After that, the operator puts the uppermost vertical column unit 67B on the third vertical column unit 58B, and puts the upper ends of the third vertical columns 59B and 60B in the third vertical column unit 58B and the uppermost vertical column. The lower ends of the uppermost vertical columns 68B and 69B in the unit 67B are joined by welding. As a result, the vertical columns 7A to 8B shown in FIGS. 1 and 2 have a predetermined axial length. The operator performs the same work on the uppermost vertical column unit 67A shown in FIG. 21.

Finally, as step S10, the remaining other steps are performed.

After that, the operator uses the electric chain block device 23 to hold the lift stand 46 temporarily placed on the bottom surface of the pit in a state of being lifted to a predetermined height, and the lift stand 46 is completed from the vertical columns 7A to 7A. It is attached to 8B and one end of the chain 72 is connected. Next, the operator connects the other end of the chain 72 to the temporarily placed weight. Further, when the main rope 63 and the like shown in FIG. 21 are carried out, the installation of the parking device is completed.

As can be seen from the above detailed explanation, when the four vertical columns 7A to 8B are configured to have a predetermined length from the beginning, the lift opening 4 leads to the inside of the pit 20, the lower floor parking portion 15 and the upper floor parking portion 17. And narrows the space when carrying in the components. However, as described above, if the four vertical columns 7A to 8B are divided under predetermined conditions and they are added while being carried in at an appropriate timing, a sufficient carrying-in space can be obtained without narrowing the space from the lift opening 4. It can be secured, and without constructing a scaffolding for large-scale work, an efficient installation process procedure can be established, and the installation work time can be shortened as a whole.

Although the above-described embodiment shows an example of a parking device installed underground, it can also be applied to a parking device installed above ground or both underground and above ground. Further, in the above-described embodiment, the storage space is formed by the second floors of the lower floor parking portion 15 and the upper floor parking portion 17, but there is also a configuration in which a third storage space is provided above the upper floor parking portion 17. Can be applied.

Further, the trays 5A, 5B, 5L to 5N used for carrying in the assembly lifting device 51 and the frame pillar 19 are not necessarily for the main installation, and a movable side tray for work having a similar shape may be used. .. When the work tray is used, first, the used work tray is carried out, and then the corresponding number of main work trays are carried in.

Further, in the above-described embodiment, the fixed side drive unit 14B for the lower floor, the fixed side drive unit 16B for the upper floor, and the tray 5M are arranged on the back side of the pit 20, but the back side of the pit 20 is installed. The present invention can also be applied to parking devices that are not used for the purpose.
