Description

TECHNICAL FIELD The present invention relates to a carrier device used for carrying a large article such as an automobile.

[Conventional technology]

With the increasing density of buildings and houses in cities, various technical studies are being made today on methods for securing traffic such as roads and railroads in deep underground. In this case, for example, when constructing a parking lot in a deep underground, it is necessary to provide a gentle large diagonal road or a loop type tunnel for connection to the ground, which is one of the entrances and exits. If the loop type tunnel is not used in this way, the conventional elevators and escalators are enlarged,
It is also possible to speed up and transport cars etc. underground.

[Problems to be Solved by the Invention]

However, in the conventional method of providing an oblique road to secure a connection path between the underground structure and the ground, even if the average climbing slope is 10% for safe driving of the vehicle, a distance of 500 m or more is required as an exit from the underground. It is difficult to secure the site and treat the exhaust gas because it is extremely difficult. In addition, if a loop type tunnel is used, it has the advantage of being able to use a narrow site three-dimensionally, but since cars passing through this tunnel must be driven to rotate in the same direction, it may lead to a rear-end collision accident due to paralysis of driving sensation. There is a problem that it becomes easy and it is necessary to fully consider exhaust gas treatment.

On the other hand, even if the conventional elevator or escalator is improved, there is a practical problem that the carrying capacity is smaller than the size and the carrying speed is constant and the carrying capacity is limited.

The present invention has been made by paying attention to the above-mentioned conventional problems, and uses a transporting means centering on a spiral drive body to rapidly and mass-transport a large amount of material in a relatively small underground space. An object of the present invention is to provide a transfer device that can safely move an object up and down with respect to the ground.

[Means for solving the problem]

The transfer device according to the present invention is provided with a spiral drive member on the rotary shaft, the wheels of the carriage are rotatably mounted on the drive member, and the carriage is guided vertically by a guide, When the rotary shaft is rotationally driven by a drive device, the cart is guided in the vertical direction. As another invention, the spiral upper part is provided with an entrance leading to the ground, and the lower part is provided with an entrance leading to the underground, making the upper and lower spiral pitches dense and setting an intermediate pitch. Roughing makes the upper and lower transport inlets move up and down slower than the central lifting unit, thus speeding up and ensuring safety.

Further, as another invention, two or more spiral drive bodies installed on a rotary shaft that is rotationally driven by a drive device are arranged side by side, and each drive body is provided with a trolley that is in contact with each other via wheels, and each trolley is moved up and down. There is a transfer device that is provided with a guide that guides each direction, and a connection guide that connects the upper and lower parts of each guide and guides the carriage in the horizontal direction, thereby improving the transfer capacity and the transfer efficiency. be able to.

Furthermore, as another invention, there is a transporting device in which at least one driving body among two or more driving bodies arranged in a spiral shape in the opposite direction to the other driving bodies is formed. When driven to rotate in the direction, at least one carriage can be guided upward and the other carriages can be guided downward in the opposite direction.

[Action]

In the spiral drive body according to the present invention, the height position of each part changes due to the rotation of the rotating shaft, while the trolley mounted on the drive body via the wheels moves only in the vertical direction by the guide. It is possible to be guided. Therefore, when the rotary shaft rotates, the drive body also rotates, the height of the place on which the carriage is mounted changes, and the carriage receives a force in the direction normal to the upper surface of the drive body. The dolly will simply move up or down along the guide. Therefore, articles such as automobiles placed on the dolly are transported in a small space between the deep underground structure and the ground.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
In FIG. 1, reference numeral 1 is a structure main body of a carrier, which is provided in a large-diameter installation hole vertically excavated deep underground. Reference numeral 2 denotes an inner wall made of concrete or iron in the structure main body 1. A space inside the inner wall 2 is provided with a rotary shaft 3 extending in a vertical direction at a central portion thereof, and the rotary shaft 3 is driven by an upper drive device 4. It is installed horizontally. If necessary, the drive device 4 may be connected to the lower part of the rotary shaft 3 to give a larger rotary drive force to the rotary shaft 3. Reference numeral 5 denotes a spiral-shaped driving body provided around the rotary shaft 3, and has a form in which the belt-like body is wound around the rotary shaft 3 so as to form a gradually rising horizontal plane. In this case, the winding pitch is partially changed, and in this part,
It is possible to increase or decrease the moving speed of the carriage as described later. 6 is a carriage mounted on a plurality of positions of the driving body 5, and these carriages 6 are
As shown in FIG. 2, a plurality of wheels 7 are provided in the lower part, and these wheels are on the driving body 5 and are rotatable. In this case, the length of the bracket 8 to which the wheel 7 is attached is set so that the carriage 6 is horizontally mounted on the driving body 5. Reference numeral 9 denotes a guide which is arranged close to the driving body 5 and which has a plurality of elevating members 10 extending vertically and supporting the carriage 6 and moving up and down. In addition, entrances and exits 11 and 12 for articles placed on the carriage 6 are provided at upper and lower portions of the inner wall 2. In addition,
The entrances and exits 11 and 12 lead to a ground road and an underground road, respectively, and in this embodiment, they serve as entrances and exits of an automobile 13 as the article to be placed.

 Next, the operation will be described.

For example, when the automobile 13 is transported from the above-ground parking lot to the ground, first, the automobile 13 is run through an auxiliary plate or the like from the above-mentioned entrance / exit 12 leading to the underground road to the carriage 6 below the guide 9, Further stop this. At this time, the driving body 5 is not driven yet or is driven very slowly. On the other hand, as above
The carriage 6 carrying 13 is on the drive body 5 via the wheels 7,
Here, the drive shaft 4 is driven to rotate the rotary shaft 3 counterclockwise (in the direction of arrow P). Then, the carriage 6 on the driving body 5 provided so as to turn to the right is
The dolly 6 which receives a force in the normal direction of the upper surface and at which the movement in the horizontal direction is restricted rotates the wheels 7 while being supported by the elevating member 10, and is guided by the guide 9 to rise. . In this way, when the dolly that rises while rotating the wheels 7 reaches the vicinity of the entrance / exit 11, the rotation speed of the rotary shaft 3 by the drive unit 4 decreases, the dolly slowly rises, and stops as necessary. Be punished. Therefore, the vehicle 13 on the dolly 6 passes through an auxiliary plate (not shown)
You can now drive to 11
You can get out of the road on the other side. In this case, by disposing a plurality of carriages 6 under the guide 9 and mounting the automobiles 13 one after another on them, these can be sequentially moved toward the upper entrance / exit 11. On the other hand, in the carrying device, the driving device 4 is driven in the opposite direction to the above, and the rotating shaft 3 is rotated in the reverse direction,

It can be moved to the lower entrance / exit 12 along and the car can be transported to the underground parking lot. In this way, by alternately repeating the normal rotation and the reverse rotation of the rotating shaft 3, it is possible to continuously enter and exit the underground parking lot. If the carrier is used only for moving the vehicle 13 to the ground, after the vehicle 13 is unloaded at the entrance / exit 11, the truck is moved to the lower part of the guide 9 by a recovery device (not shown). Become.

Further, by arbitrarily setting the pitch interval of the spiral-shaped driving body 5 on which the dolly 6 is placed, the dolly 6 is slowly moved in a place where the pitch is narrow and the dolly 6 is moved at a high speed in a place where the pitch is wide. Can be made. For example, the pitch between the loading and unloading sections near the upper and lower entrances 11 and 12 is made dense, and the pitch between the central elevating and lowering sections sandwiched between the loading and unloading sections is made coarse so that the former moves slower and the latter moves faster . By doing so, it is possible to safely and swiftly enter / exit the deep underground structure without traveling the vehicle 13 itself, and the carrying capacity becomes extremely high.

FIG. 3 shows another embodiment of the present invention. In this embodiment, the structure body 1A of the descending transfer device is arranged in parallel to the structure body 1 of the ascending transfer device. In this case, the spiral-shaped drive body 5A on the structure body 1A side is provided on the rotary shaft 3A at a pitch in the opposite direction to the one drive body 5, and the rotary shafts 3 and 3A are connected to the drive device 4 respectively. , 4A rotate in the same direction. In addition, the reference numeral A is attached to the other portions corresponding to those shown in FIG.

According to this embodiment, the pitches of the driving bodies 5A, 5 are opposite to each other. Therefore, by rotating the rotary shafts 3, 3A by the driving devices 4, 4A in the same direction (arrow P direction), the driving bodies 5A, 5A are rotated. Can raise the vehicle 13 along the guide 9, and the driving body 5A can lower the vehicle 13 along the guide 9A. In this case, the upper and lower parts of the guides 9 and 9A are connected horizontally as shown in the drawing.
By connecting 5 and 16, respectively, the carriage 6 can be moved while circulating these guides 9, 9A, 15, 16 and the vehicle 13 can be transported more efficiently. Further, in this embodiment, the pitch of the driving bodies 5A is set in the same direction as that of the driving bodies 5, and the driving device 4A is connected to the driving device 4A.
The same action and effect can be obtained by driving in the opposite direction. In the above description, the case where the drive devices 4 and 4A are individually provided has been described, but one of these may be shared for rotational drive of the rotary shafts 3 and 3A, and the installation space can be narrowed. . Further, when necessary, it is easy to drive both of the driving bodies 5 and 5A in the direction in which the dolly 6 is raised, and it is possible to cope with an emergency evacuation from the underground.

In the above embodiment, the driving bodies 5 and 5A are provided by providing the belt-shaped body in a spiral shape around the rotary shafts 3 and 3A. However, in order to reduce the weight, it is easy to guide each wheel 7. It can also be a rail body.
