Description

The present invention relates to mechanical parking installation comprising a vehicle lifting equipment for lifting the pallet equipped with the vehicle in a parking tower.

  Conventionally, a multi-level parking shelf is provided in the vertical direction of the parking tower, and the pallet on which the vehicle is mounted is moved up and down by a vehicle lifting device that moves up and down in the vertical direction of the parking tower, and the pallet is loaded into an empty parking shelf. Alternatively, there is a mechanical parking facility configured to unload the pallet from the parking shelf.

  This mechanical parking facility is a so-called elevator parking facility, and in this elevator parking facility, the vertical position of the vehicle lifting device suspended is controlled by the drive control of the elevator lifting drive device provided at the upper part of the parking tower. In addition, entry on the ground entry floor, pallet loading to a predetermined parking rack, or pallet unloading are performed.

As a conventional technique related to this type of elevator parking apparatus, as shown in FIGS. 16 (a) to 16 (c), a vehicle elevating apparatus 100 that elevates and lowers the inside of a parking tower as shown in longitudinal sectional views at the time of each operation. There is a parking device in which the revolving frame 104 on which the pallet 103 is placed is supported by a vertically moving guide leg 102 suspended from four corners so as to be movable up and down (see, for example, Patent Document 1). In this parking apparatus, the lower end of the guide leg 102 of the turning frame 104 serves as a seat plate 105, and the pallet 103 is turned and the vehicle is loaded and unloaded while the seat plate 105 is seated on the pit floor surface 106. Is called.
Japanese Patent Laying-Open No. 2003-49555 (page 6-7, FIGS. 7, 8, and 11)

  However, in the case of the aforementioned Patent Document 1, when the pallet 103 is turned, the lifting frame 101 reaches the loading / unloading floor, and the seat plate 105 of the turning frame 104 is landed on the pit floor surface 106 as shown in FIG. The pallet 103 on which the vehicle is mounted is further lowered from the state shown in FIG. 16 to the revolving frame 104 from the elevating frame 101 to the state shown in FIG. Therefore, when the pallet 103 is swung, it is necessary to provide the boarding deck 107 at a position retracted downward from the pallet 103 so that the pallet can be swung.

  For this reason, when the vehicle enters and exits in the state shown in FIG. 16 (c), it is inevitably between the road surface 108 of the pallet 103 and the upper surface of the boarding deck 107 and between the boarding floor 109 and the boarding board 107. A step h is formed between the upper surface and the upper surface of the door, making it difficult for the user to get on and off.

  In order to solve this structure that is difficult to get on and off, for example, it is conceivable that the boarding deck is configured as a lifting deck and the deck is raised to the pallet road surface so as to eliminate the level difference only when boarding and lowering. Is complicated and requires a large amount of equipment cost, and the work steps for loading and unloading the deck are increased and the loading / unloading time is prolonged.

  In addition, the fine movement control (for example, the position control between the vehicle entry level, the pallet turning level, and the pallet lateral feed direction switching level) of the relative elevation between the lifting frame 101 and the turning frame 104 is all performed by the elevator lifting drive device. Since it is performed by drive control, complicated drive control of the suspended vehicle lifting apparatus 100 is required.

  In addition, since the seat plate 105 is landed on the pit floor surface 106 every time it enters and leaves, an impact sound may be accompanied each time, resulting in a noise problem.

When the revolving frame 25 is revolving, the revolving frame 25 is revolved by engaging the engaging protrusion 43 of the first arm 35 with the longitudinal groove member 45 of the revolving frame 25 and revolving the first arm 35.

  On the other hand, as shown in FIGS. 4 and 7, an engagement mechanism 46 that prevents the turning frame 25 from turning is provided between the elevating frame 23 and the turning frame 25. The engaging mechanism 46 includes a longitudinal groove member 47 provided on the inner side of the elevating frame 23 and an engaging piece 48 provided on the outer side of the turning frame 25.

  Therefore, by extending the piston cylinder 53, the connecting member 51 protrudes toward the parking shelf 7, and the elevating frame 23 is connected to the parking shelf 7 side by engaging the connecting member 51 with the engaging member 52. By contracting the piston cylinder 53, the connection of the elevating frame 23 is released.

  FIG. 8 is a schematic diagram of a hydraulic circuit provided in the vehicle lifting apparatus shown in FIG. As shown in the figure, the elevating frame 23 is provided with a hydraulic unit 55 that drives a ram cylinder 26 that supports the revolving frame 25 and a piston cylinder 53 of the locking device 50. The hydraulic unit 55 includes a pump 56 provided in a hydraulic pressure source 71 (tank), a turning frame circuit 57 that drives the ram cylinder 26 with pressure oil discharged from the pump 56, and a piston cylinder 53. A locking device circuit 58 is provided. In this example, the locking device circuit 58 includes the configuration of the pump 56 and the like common to the turning frame circuit 57, but the common configuration is configured as a separate circuit regardless of which circuit is included.

These switching valves 60 and 61 open and close the piping 59. A check valve 72 is provided in the supply path from the pump 56, and the discharge is performed via the electromagnetic switching valve 61. Reference numeral 62 denotes a throttle that adjusts the amount of oil discharged from the ram cylinder 26, thereby adjusting the lowering speed of the ram cylinder 26. 63 is a safety valve that allows pressure oil to escape when the pressure in the pipe 59 rises. The electromagnetic switching valve 61, the throttle 62, the safety valve 63, and the check valve 72 constitute a lift valve portion 76. Further, the pipe 59 to each ram cylinder 26 is a pipe branched from the electromagnetic switching valve 60, and is configured to raise the elevating frame 23 in a well-balanced manner by connecting all of them. The electromagnetic switching valve 60 and the base portion of the pipe 59 constitute a branching portion 77.

  The locking device circuit 58 includes a pipe 64 for supplying pressure oil to the piston side of the piston cylinder 53, a pipe 65 for supplying pressure oil to the rod side, and pressure oil to these pipes 64, 65, or Electromagnetic switching valves 66 and 67 for switching so that the pressure oil is discharged from these pipes 64 and 65 are provided. The electromagnetic switching valve 66 is a four-port switching valve that supplies and discharges pressure oil to and from the piston side and the rod side of the piston cylinder 53. The electromagnetic switching valve 67 is a poppet valve and supplies and shuts off the pressure oil to the pipes 64 and 65. The pipe 64 is provided with a throttle 68 for adjusting the speed when the piston cylinder 53 is extended. Reference numeral 69 denotes a safety valve that allows pressure oil to escape when the pressure in the pipes 64 and 65 rises, and reference numeral 70 denotes a filter. Such a hydraulic unit 55 is configured to expand and contract the piston cylinder 53 of the locking device 50 and extend the ram cylinder 26 of the revolving frame 25.

  Thus, the ram cylinder 26 for raising and lowering the turning frame 25 and the piston cylinder 53 of the locking device 50 are driven by a common hydraulic unit 55, and the hydraulic unit 55 is provided on the elevating frame 23, whereby the vehicle elevating device 13. Can be formed compactly.

  9 is a drawing of an embodiment in which pressure detection means is added to the hydraulic circuit shown in FIG. 8, (a) is a hydraulic circuit diagram in which a pressure sensor is added as pressure detection means, and (b) is a pressure switch as pressure detection means. It is a hydraulic circuit diagram to which is added. In these examples shown in FIGS. 9A and 9B, the pressure of the hydraulic oil supplied to the elevating hydraulic cylinder 26 (FIG. 8) indicates that an overweight vehicle M is mounted on the pallet 9 (FIG. 4). It is designed to detect changes. In these drawings, the components shown in FIG. 8 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 9A, the pressure sensor 73 is provided between the electromagnetic switching valve 60 and the pipe 59 of the branching portion 77 in the turning frame circuit 57. The pressure sensor 73 detects the pressure of the pressure oil in the pipe 59 supplied to the ram cylinder 26 (FIG. 8), and the detected pressure signal is transmitted to the control device (not shown) of the parking facility 1 via the wiring 74. It is configured to be entered. It is determined whether or not the pressure signal input to the control device exceeds a settable weight value that can be stored in the control device in advance. This determination is made by preliminarily registering a weight that can be stored in the parking facility 1 as a set value in the control device and comparing it with the set value. And when it exceeds the set value, it is determined that “no warehousing due to excess weight”, and the subsequent driving of the parking facility 1 is not permitted. As described above, when the pressure oil pressure supplied to the ram cylinder 26 is detected by the pressure sensor 73, the pressure change can be accurately detected by the pressure sensor 73, so that it is possible to accurately detect the excess weight.

  As shown in FIG. 9B, the pressure switch 75 is also provided between the electromagnetic switching valve 60 and the pipe 59 of the branching portion 77 in the turning frame circuit 57. The pressure switch 75 is switched when the pressure of the pressure oil supplied to the ram cylinder 26 (FIG. 8) exceeds a preset value set in the pressure switch 75, and the switched signal is transmitted via the wiring 74. And input to a control device (not shown). When it is input that the pressure switch 75 has been switched to the control device, it is determined that “the vehicle cannot be stored due to excess weight”, and the subsequent driving of the parking facility 1 is not permitted. In this way, when the pressure oil pressure supplied to the ram cylinder 26 is detected by the pressure switch 75, the pressure oil pressure is detected by mechanically adjusting the set pressure of the pressure switch 75, so that pressure detection accuracy is required. The pressure sensor 73 is more preferable.

  As described above, in the example shown in FIGS. 9 (a) and 9 (b), the pressure detection means for detecting the pressure of the pressure oil supplied to the ram cylinder 26 is provided, and the vehicle is mounted on the pallet 9 (FIG. 4). When the weight of M (FIG. 4) increases, the pressure oil pressure supplied to the ram cylinder 26 is detected by the pressure detecting means using the fact that the pressure of the pressure oil supplied to the ram cylinder 26 (FIG. 8) increases. From this detected value, it is possible to quickly prevent a vehicle having a weight that cannot be mounted from being stored. The pressure sensor 73 and the pressure switch 75 in this embodiment are examples of pressure detection means, and may have other configurations.

  In addition, when it is detected that the weight of the vehicle M exceeds the storable weight, a control signal for disabling the driving of the parking facility 1 is issued to stop the storage of the vehicle. A warning “excessive vehicle weight” may be issued to a display (not shown) or the like to notify the operator of this.

  By the way, in the hydraulic circuit shown in FIGS. 8 and 9, the pressure of each ram cylinder 26 is applied to four pipes 59 provided in parallel from the lift valve portion 76 through the electromagnetic switching valve 60 (poppet valve) of the branching portion 77. Oil is supplied. However, the load distribution of the mounted vehicle is various, and it is inevitable that an uneven load (uneven load) acts on the pallet 9 supported by the four ram cylinders 26 via the turning frame 25. For example, in general automobiles, the load on the front part of the vehicle on which the engine is mounted is generally larger than the load on the rear part of the vehicle. Uneven load is applied. Depending on the magnitude of the unbalanced load, it may be difficult to mount the vehicle.

  Therefore, the structure for supporting the pallet 9 (in this embodiment, the turning frame 25) and the upper ends of the rods of the four ram cylinders 26 are mechanically coupled, and the four ram cylinders 26 are connected by a kind of tuning means. It is also possible to support it as it was done. However, even if the upper ends of the ram cylinders 26 are mechanically coupled in this way, the ram cylinders 26 are connected in parallel in the hydraulic circuit shown in FIG. A large amount of the supplied pressure oil flows toward the ram cylinder (in the above description, the vehicle rear side) with a small acting load (load), and it may be difficult to keep the pallet 9 horizontal.

  In such a case, the hydraulic pressure is synchronized between the plurality of lifting hydraulic cylinders 26 by configuring the hydraulic circuit as shown in a schematic diagram of another example of the hydraulic circuit of FIG. 8 shown in FIG. Thus, the pallet 9 may be kept horizontal. 10, the same components as those in the hydraulic circuit shown in FIG. 8 are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in FIG. 10, in this hydraulic circuit, a hydraulic tuning circuit unit having a shunt collecting valve 78 and an electromagnetic switching valve (poppet valve) 79 instead of the branching unit 77 in the turning frame circuit 57 shown in FIG. 80 is provided. In the hydraulic tuning circuit unit 80, a pipe 81 is branched into two systems by a diversion collecting valve 78, and an electromagnetic switching valve 79 is provided in each pipe 81.
On the other hand, the elevating hydraulic cylinder 26 (FIG. 8) that supports the pallet 9 from below through the revolving frame 25 moves up and down at the left and right positions at the front and rear positions of the elevating frame 23 that elevates the revolving frame 25 that supports the pallet 9. One of the hydraulic cylinders 26 is a parent cylinder 26a (piston cylinder) and the other is a child cylinder 26b (ram cylinder), and is connected in series so as to supply pressure oil from the rod side of the parent cylinder 26a to the piston side of the child cylinder 26b. ing. That is, among the four lifting hydraulic cylinders 26 in FIG. 8, the left and right cylinders 26 (for example, two on the left side in FIG. 8) provided on the front side of the lifting frame 23 are referred to as a parent cylinder 26a and a child cylinder 26b. The left and right cylinders 26 (for example, two on the right side shown in FIG. 8) provided on the rear side are used as a parent cylinder 26a and a child cylinder 26b, so that each pair forms a pair (parent cylinder 26a). Piston cylinder + child cylinder 26b; ram cylinder), and two sets are connected in series (the rod side of the piston cylinder 26a and the piston side of the ram cylinder 26b are connected). A pipe 81 branched by the branch flow collecting valve 78 of the hydraulic tuning circuit 80 is connected to the piston side of each parent cylinder 26a at the front and rear positions of the lifting frame 23 via an electromagnetic switching valve 79. Further, the rod side of each parent / child cylinder 26a is connected to the piston side of each child cylinder 26b. Thus, the pressure oil is supplied to the piston side of each parent cylinder 26a via the electromagnetic switching valve 79, and the pressure oil is supplied from the rod side of each parent cylinder 26a to the piston side of each child cylinder 26b. Yes.

  Further, the hydraulic tuning circuit unit 80 is provided with a bypass circuit 82 for connecting the piston side of each child cylinder 26b and the pipe 81 on the downstream side of the diversion collecting valve 78 for each group. This bypass circuit 82 is provided with an electromagnetic switching valve 83. The electromagnetic switching valve 83 is normally closed. By opening and closing the electromagnetic switching valve 83, the amount of oil in the closed circuit in which the parent cylinder 26a and the child cylinder 26b are provided can be adjusted.

  In this embodiment, the bypass circuit 82 is provided in the hydraulic tuning circuit unit 80, but the bypass circuit 82 is not necessarily provided. Further, in place of the bypass circuit 82, a coupler socket or the like may be provided on the side of the child cylinder 26b, and oil replacement or refilling may be performed manually during periodic maintenance inspections. This configuration can be applied even when all of the lifting hydraulic cylinders are composed of ram cylinders 26 as shown in FIG.

  According to such a configuration, by opening and closing the electromagnetic switching valve 79 with the electromagnetic switching valve 83 of the bypass circuit 82 closed, the parent cylinder 26a and the child cylinder 26b at the front and rear positions of the lifting frame 23 are Since the pressure oil pressure distributed and supplied by the branch flow collecting valve 78 is synchronized, the pressure oil pressure can be synchronized with each other at the front and rear positions of the lift frame 23. Therefore, even when storing vehicles with significantly different front and rear weights, the weight difference between the front and rear of the pallet 9 can be reduced by appropriately setting the distribution ratio by the diverting collecting valve 78 to the front and rear of the pallet 9. Stable support can be achieved by synchronizing the pressure oil pressure between the cylinder 26b and the cylinder 26b.

  In this embodiment, since the bypass circuit 82 is provided as described above, the oil in the closed circuit in which the parent cylinder 26a and the child cylinder 26b are provided leaks from the seal portion or the like, and the amount of oil needs to be adjusted. Even if this occurs, the amount of oil (hydraulic pressure) in the closed circuit can be easily adjusted by opening / closing the electromagnetic switching valve 83 of the bypass circuit 82. Furthermore, by opening only the electromagnetic switching valve 83, only the ram cylinder 26 at that position can be operated. For example, when it becomes necessary to adjust the horizontal state of the pallet 9, the electromagnetic switching valve 83 By opening and closing 83, the cylinder position can be adjusted and the pallet 9 can be brought into a horizontal state.

  11 is a schematic diagram showing a connection example of the lifting hydraulic cylinder in the hydraulic circuit shown in FIG. 10, (a) is a schematic diagram of the connection example of FIG. 10, and (b) is a schematic diagram of another connection example. . In these drawings, description will be made using reference numerals of the configuration in FIG. In addition, description of the electromagnetic switching valve 79 is omitted.

  As shown in the schematic diagram of FIG. 11 (a), in the hydraulic tuning circuit section 80 shown in FIG. 10, the left and right cylinders 26a at the front and rear positions of the pipe 81 and the pallet 9 divided into two systems by the diversion collecting valve 78, 26b is connected in series, and the pallet 9 is supported from below by two sets of parent and child cylinders 26a and 26b provided before and after the pallet 9, so that the weight balance of the pallet 9 is maintained. I have to.

  On the other hand, in an elevator parking facility to which the present invention is applied, the pallet 9 may be turned to change the direction of the mounted vehicle. When the pallet 9 turns, the load (load) applied to the two sets of parent and child cylinders 26a and 26b may be reversed depending on the turning angle. For example, even if a pair of parent and child cylinders 26a and 26b is arranged separately for the front part and the rear part in the vehicle entry direction, if the pallet 9 carrying a vehicle with greatly different front and rear weights is turned 180 °, The front and rear positions and the left and right positions of the pallet 9 are reversed, and the load position is also reversed. Even if the pallet 9 is turned 90 °, the load position changes. Therefore, an unbalanced load is generated due to a weight difference due to a change in the load position. That is, when the pallet 9 does not turn, the set pressure of the shunt collecting valve 78 is appropriately set so that, for example, the cylinder set pressure on the heavy vehicle front side is increased and the cylinder set pressure on the light vehicle rear side is reduced. The optimum value may be set. However, in the case of a configuration in which the pallet 9 is swung, an unbalanced load is applied to the parent and child cylinders 26a and 26b. It becomes difficult to tune alone.

  Therefore, as shown in a schematic diagram of another connection example in FIG. 11 (b), a total of 2 cylinders each consisting of two cylinders, each consisting of a parent cylinder 26a (piston cylinder) and a child cylinder 26b (ram cylinder). These parent and child cylinders 26a and 26b are connected in a diagonal manner so that one of the front and rear parent cylinders 26a at the left and right positions of the pallet 9 and the other front and rear child cylinders 26b at the left and right positions are connected. , 26b. The rod side of the diagonally connected parent cylinder 26a and the piston side of the child cylinder 26b are connected in series, and the pressure oil distributed by the flow dividing valve 78 is supplied to the respective parent-child cylinders 26a and 26b. Constitute. In the case of this configuration, when pressure oil is supplied to the piston side of each parent cylinder 26a via the electromagnetic switching valve 79 (FIG. 10), the pressure oil flows from the rod side of this parent / child cylinder 26a to the piston side of the child cylinder 26b. Thus, the child cylinder 26b at the diagonal position can be hydraulically tuned. In the case of this configuration, even if the distribution ratio of the diversion collecting valve 78 is appropriately set to be large before and after the pallet 9, the weight balance at the left and right positions of the pallet 9 and the weight balance at the front and rear positions can be maintained.

  That is, in the case of diagonal connection, the parent and child cylinders 26a and 26b are synchronized with each other as a combination of a large load and a small load at the diagonal position of the pallet 9. The unbalanced load applied to the cylinder is moderately distributed so that a large variation in the load (load) difference between the two cylinders 26a and 26b does not occur at any angle turning (non-turning, 90 ° turning, 180 ° turning). Can be. In other words, the center of gravity of the vehicle mounted by turning the pallet 9 is changed in the front-rear direction and the left-right direction on the pallet 9 by connecting the two parent-child cylinders 26a and 26b diagonally in this way. Even if the load acting on each cylinder 26 changes, the hydraulic pressures of the cylinders 26 arranged in the front-rear position can be synchronized to support the vehicle in a favorable weight balance. In addition, with such a configuration, it is possible to use an electromagnetic switching valve 26 (poppet electromagnetic valve) having a sensitive switching response.

  Therefore, with the configuration as shown in FIG. 11 (b), even when a vehicle having a significantly different front and rear weight is stored, even if a difference in weight between the front and rear of the pallet 9 and a change in the load application position due to turning or the like occur. Stable support can be achieved by synchronizing the pressure oil pressures of the parent and child cylinders 26a and 26b arranged at the front and rear positions and the left and right positions.

  The pallet 9 is supported by the parent and child cylinders 26a and 26b divided into two systems by the diversion collecting valve 78, and the upper ends of the rods of the parent and child cylinders 26a and 26b and the lower surface of the swivel frame 25 (FIG. 8) for supporting the pallet 9. May be mechanically coupled. Moreover, what is necessary is just to set these as preferable structures according to conditions, such as the length of the pallet 9, arrangement | positioning of the parent-child cylinders 26a and 26b for raising / lowering, and the vehicle weight which can be stored.

  12 (a) to 12 (c) are schematic views in plan view showing the lateral feeding operation of the pallet to the parking rack by the vehicle lifting device, and FIGS. 13 (a) to 13 (c) are the operating states of the locking device. It is a schematic diagram of the side view which shows. The traversing drive operation of the pallet by the above-described turning drive device 30 and the locking device 50 will be described with reference to these drawings. Since the carrying-in (storing) operation of the pallet 9 and the carrying-out (receiving) operation (transverse operation) are the same, the carrying-in operation of the pallet 9 will be described as an example.

  As shown in FIG. 12 (a), the first arm 35 is moved in a predetermined direction so that the angle formed by the first and second arms 35 and 36 is not changed by the two motors 33 and 34 (FIG. 5) of the turning drive device 30. And the engaging roller 44 is engaged with the engaging groove 49. Before the pallet 9 is traversed, the connecting member 51 is parked by extending the piston cylinder 53 as shown in FIG. 13 (b) from the standby state of the locking device 50 shown in FIG. 13 (a). It protrudes in the direction of the shelf 7 and is engaged with the engaging member 52 of the parking shelf 7. Thereby, the vehicle elevating device 13 and the parking rack 7 are connected.

  Next, as shown in FIG. 12B, the two motors 33 and 34 are appropriately driven so that the engaging roller 44 moves the pallet 9 in the width direction. Thereby, the wheel 11 of the pallet 9 moves along the rails 27, 8, and the pallet 9 is caused to traverse toward the parking rack 7. At this time, since the vehicle elevating device 13 is connected to the parking shelf 7 by the locking device 50, the pallet 9 can be transported with a stable traversing motion.

  Then, as shown in FIG. 12 (c), when the pallet 9 is placed in the parking rack 7, the second arm 36 is turned so that the first arm 35 does not rotate, and the engagement roller 44 is detached from the engagement groove 49. (Shown with a two-dot chain line). Thereby, carrying in of the pallet 9 is completed. At this time, as shown in FIG. 13 (c), the piston cylinder 53 is also contracted, and the connection of the engagement member 52 of the parking rack 7 by the connection member 51 is released.

  As described above, the carrying-in operation has been described in this description. However, when the pallet 9 is carried out from the parking shelf 7, both arms 35 and 36 are operated in the reverse procedure. Note that Japanese Patent Application No. 2001-239116 relating to the applicant's application is detailed regarding the driving of the first and second arms 35 and 36.

  Next, the operation in the pit by the vehicle lifting / lowering device 13 configured as described above will be described. 14 is a longitudinal sectional view showing a state in which the turning frame of the vehicle lifting apparatus shown in FIG. 4 is in the turning position, and FIG. 15 is a longitudinal sectional view showing a state of the vehicle lifting apparatus shown in FIG. FIG. In these figures, the hydraulic circuit shown in FIG. 8 will be described as an example.

  First, the state shown in FIG. 4 described above is a state in which the vehicle M is loaded and unloaded at the loading / unloading unit 20 (FIG. 1), and the vehicle lifting and lowering device 13 is lifted as it is, and the pallet 9 is placed on any parking shelf 7. In a state where the pallet 9 can be stored. In this state, the road surface 10 of the pallet 9 is formed flush with the upper surface (entrance floor surface) of the entry / exit deck 22.

  Therefore, the pallet vehicle road surface 10 is at the same level as the boarding / alighting deck 22 on the loading / unloading floor, so that the user can easily get on and off. Moreover, when the vehicle elevating device 13 reaches the entry / exit floor, the elevating frame 23, the turning frame 25, and the like carry the vehicle M and lift the pallet 9 while floating from the floor of the pit 21, so the entry / exit floor There is no pit floor landing impact or landing noise every time it reaches. In addition, the piston cylinder 53 is employed as the actuator of the locking device 50, and the ram cylinder 26 is employed as the lifting drive for the swivel frame 25 so that these are driven by the common hydraulic unit 55. Can be made compact.

  Further, in this state, the piston rod 28 of the ram cylinder 26 that raises and lowers the revolving frame 25 is at the lower end position, and the pallet 9 is in a state where the wheels 11 are placed on the transverse rail 27. Moreover, since the turning of the engaging piece 48 is prevented by the longitudinal groove member 47, the turning frame 25 is in a non-turning state and keeps the pallet 9 carrying the vehicle M stably held. Can do. When the pallet 9 is stored in the parking shelf 7 from this state, since the engaging roller 44 is engaged with the engaging groove 49 provided on the right side of the pallet 9, the pallet 9 is moved up to a predetermined parking shelf 7 position, The pallet is stored in the parking shelf 7 provided on the left side of the hoistway 12 in FIG.

  The state shown in FIG. 14 shows a state where the pallet 9 is turned. As shown in the figure, when the pallet 9 is turned, the pallet 9 is lifted by a predetermined amount by the turning frame 25. This lifting is performed by extending a ram cylinder 26 provided on the lifting frame 23. In this example, by extending the ram cylinder 26, the turning frame 25 is lifted up to the level c at the time of lifting and turning in FIG. 7, and the pallet 9 and the vehicle M together with the turning frame 25 are lifted upward from the lifting frame 23. It is done. As a result, the engagement piece 48 provided in the turning frame 25 is disengaged from the longitudinal groove member 47 provided in the elevating frame 23, and the first arm 35 of the turning drive device 30 provided in the turning frame 25. It will be in the state engaged with the engagement protrusion 43 provided in the front-end | tip. In this state, the lowermost surface of the pallet 9 is slightly higher than the upper surface of the boarding deck 22.

  Then, the first arm 35 and the second arm 36 of the turning drive device 30 are integrally turned by the first motor 33, whereby the turning frame 25 supported by the turning bearing 29 is turned to turn the pallet 9. Is done. This turning is performed at a predetermined angle (for example, 90 °, 180 °) by controlling the rotation angle of the first motor 33.

  Thus, by setting the turning level of the pallet 9 on the entry / exit floor above the entry floor, the entry floor (the entry / exit deck 22) is at the same level as the pallet vehicle road surface 10 when getting on / off as described above. I have to.

  FIG. 15 is a longitudinal sectional view showing a state when the pallet transverse feed direction of the vehicle elevating device shown in FIG. 4 is switched. In the state shown in FIG. 4, the pallet 9 is stored in the parking shelf 7 provided on the left side of the hoistway 12, but the pallet 9 is stored in the parking shelf 7 provided on the right side of the hoistway 12. The switching operation will be described below.

  As shown in the drawing, when the pallet 9 is moved laterally to the right parking shelf 7, the turning frame 25 is slightly lifted by the ram cylinder 26. The amount of lifting of the swivel frame 25 is such that the engagement piece 48 provided on the swivel frame 25 is engaged with the longitudinal groove member 47 provided on the elevating frame 23 and the engagement roller of the second arm is maintained. 43 is disengaged downward from the engagement groove 49 of the pallet 9, and the engagement protrusion 43 provided at the tip of the first arm 35 of the turning drive device 30 is in a state of disengagement from the longitudinal groove member 45. It is lifted by an amount corresponding to the transverse feed direction switching level b in FIG.

  In this state, if the first arm 35 and the second arm 36 are integrally rotated leftward by the turning drive device 30, the turning frame 25 is prevented from turning by the longitudinal groove member 47 provided in the lifting frame 23. In this state, only the arms 35 and 36 can be moved to the left side. Thereafter, when the pressure oil in the ram cylinder 26 is removed, the turning frame 25 is lowered by its own weight, and the wheels 11 of the pallet 9 are placed on the transverse rails 27 of the elevating frame 23. If it will be in this state, the engagement roller 44 of the turning drive device 30 will be engaged with the engagement groove 49 provided in the lower left side surface of the pallet 9. As a result, the first arm 35 and the second arm 36 in FIG. 4 are moved to the left in the drawing.

  When the pallet 9 is stored in the parking shelf 7 from this state, the engagement roller 44 is engaged with the engagement groove 49 provided on the left side of the pallet 9 (engagement in the left-right reverse market in FIG. 4). After raising to the predetermined parking shelf 7 position, the pallet is stored in the parking shelf 7 provided on the right side of the hoistway 12. Since this storage is the same as the reverse operation of the turning drive device 30 having the function of the traverse drive device shown in FIGS. 12 and 13 and the operation of the locking device 50, the description thereof is omitted.

  In the above-described embodiment, the ram cylinder 26, which is an elevator, and the piston cylinder 53 of the locking device 50 are driven by the same hydraulic unit 55. However, the present invention is not limited to the above-described embodiment.

  Furthermore, the above-described embodiment shows an example, and various modifications can be made without departing from the spirit of the present invention, and the present invention is not limited to the above-described embodiment.
