Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a multi-story parking system in which a plurality of vehicle-mounted pallets hung on an endless chain are circulated vertically, and more specifically, a lateral sway of a vehicle-mounted pallet hung on an endless chain is prevented. It relates to the multi-level parking device.

[0002]

[Prior art]

 As shown in FIG. 4 and FIG. 5, the multi-level parking system that vertically circulates the vehicle mounting pallet has an endless chain 4 that is wound between the upper and lower sprockets 2 and 3 at the front and rear positions in the main frame 1. And 4 are provided so as to face each other, and a plurality of outwardly projecting support arms 5 are attached to both endless chains 4 and 4 at a constant pitch in the circumferential direction. The pallet 6 is attached in a suspended manner by the suspension shaft 7, and the vehicle mounting pallet 6 is circulated by the rotation of the endless chains 4, 4 by the motor 9 of the drive source 8 and is provided in the lower front portion of the main frame 1. At the entrance / exit 10, the vehicle can be loaded and unloaded from the vehicle-mounted pallet 6 that stops at the bottom.

In the above-described multi-level parking apparatus, the vehicle mounting pallet 6 has the gate-shaped suspension frames 12 and 12 standing up and down in front of and behind the bottom plate 11, and the suspension shaft 7 installed above the suspension frames 12 and 12. Since both ends of the suspension shaft 7 are formed and supported by the ends of the support arms 5 protruding from the endless chains 4, 4, the suspension shaft 7 is suspended so that it can be oscillated by the suspension shaft 7 as a fulcrum during circulating movement. This will occur.

For this reason, conventionally, as shown in FIG. 6, the guide rollers 13 and 13 are mounted at positions on both sides of the suspension frame 7 above the one-side suspension frame 12 in the vehicle mounting pallet 6, and the guide rollers 13 are also attached. A guide rail 14 that holds and guides the guide rollers 13 and 13 is fixedly arranged on the main frame 1 along the movement loci of the guide rollers 13 and 13, and is guided by the guide rollers 13 and 13 and the guide rails 14 of the vehicle mounting pallet 6. It was designed to prevent the occurrence of lateral shake during circular movement.

[0005]

[Problems to be solved by the device]

 However, since the conventional guide rollers 13, 13 are mounted on both sides of the suspension shaft 7 on substantially the same horizontal line as the suspension shaft 7 as shown in FIG. 3, they are generated around the suspension shaft 7. With respect to the lateral shake, the effect of suppressing the lateral shake is small, and there is a problem that the vehicle mount pallet 6 is laterally shaken due to the clearance required between the lateral rail and the guide rail 14.

In particular, when the vehicle mounting pallet 6 moves along the arcuate portions of the upper and lower ends of the endless chains 4, 4, the pallet 6 is moved vertically and laterally. In the arcuate portion, if the suspension shaft 7 and the guide roller 13 are in a horizontal positional relationship, the function of suppressing the lateral movement of the guide roller 13 is significantly deteriorated. It tends to occur. Therefore, an object of the present invention is to provide a multi-level parking device that can reliably prevent the lateral sway of a vehicle pallet from occurring.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a guide roller for steady rest mounted at a position lower than the suspension shaft of the vehicle mounting pallet, and the guide roller is provided on both sides of the main frame along the movement path of the guide roller. The guide rail for holding and guiding the roller is fixed and provided.

In this invention, the vehicle mounting pallet is formed by vertically arranging a gate-shaped suspension frame at the front and rear of the bottom plate, and suspending a suspension shaft between the front and rear suspension frames. The guide rails are installed on both sides of the outer surface of the main frame close to the bottom plate, or the guide rails are installed separately on both sides of the main frame so as to guide the part that moves outside the circulating guide roller. It is also possible to adopt a structure in which the upper and lower ends of the part are bent in an arc shape.

[0009]

[Action]

 When the vehicle-mounted pallet is circulated by the rotation of the endless chain by the drive source, the guide rollers provided on the pallet ascend or descend while being guided by the guide. Since the guide roller is mounted below the suspension shaft and close to the bottom plate, the guide roller is located below the suspension shaft that serves as a fulcrum against lateral shake that may occur on the vehicle mounting pallet. With the guide rails, it is possible to reliably prevent the occurrence of lateral shake.

Further, even when the vehicle mounting pallet passes through the upper and lower arcuate portions, the guide roller is located below the suspension shaft, so that the function of suppressing the lateral movement can be maintained and the occurrence of the lateral shake can be prevented. it can.
