  It is an object of the present invention to provide a mechanical parking device that can greatly reduce the weight of a frame.

  As a result of intensive studies on a mechanical parking device having a configuration that can greatly reduce the weight of the frame, the present inventors have newly found the following facts.

  When raising and lowering the lifting pallet, the drive motor has a driving force or holding force to lift the lifting pallet against the lifting load of the lifting pallet (including the vehicle when the vehicle is on the lifting pallet). Is generated. When lowering the lifting pallet, the drive motor applies driving force to lower the lifting pallet while holding the lifting load of the lifting pallet (including the vehicle when a vehicle is on the lifting pallet). Is generated. Further, when the lifting pallet is kept at the stop position, the drive motor generates a driving force that balances the lifting load of the lifting pallet (including the vehicle when the vehicle is on the lifting pallet). . Therefore, the torsional torque acts on the beam provided with the drive motor due to the drive reaction force according to the drive force of the drive motor, and the specifications such as the size and strength of the beam provided with each drive motor are as described above. It must be set in consideration of torsional torque.

  In order to reduce the weight of the frame, the first drive motor and the second drive motor may be provided on the same beam, and one beam provided with the first drive motor and the second drive motor may be considered. However, it is necessary to increase the size and strength of the beam in consideration of receiving the driving reaction force from the two drive motors. For this reason, the merit of weight reduction by providing the 1st drive motor and the 2nd drive motor in the same beam will reduce. Therefore, if the drive reaction force acting on the beam from the two drive motors can be reduced, an increase in the size and required strength of the beam in which the first drive motor and the second drive motor are provided can be suppressed. It becomes possible to greatly reduce the weight of the body.

Based on such research results, the mechanical parking device according to the present invention includes a frame including a plurality of support columns and a beam laid between the plurality of support columns, and a lower stage provided to be movable up and down with respect to the frame member.

The first drive motor and the second drive motor rotate in such a way that the drive reaction forces acting on the beams are in opposite directions.

  In the mechanical parking apparatus according to the present invention, since the first drive motor and the second drive motor are provided on the same beam, the frame body is significantly lighter than the configuration provided on different beams. Can be realized.

  In the present invention, the first drive motor and the second drive motor are set to rotate in such a way that the drive reaction forces acting on the beams are opposite to each other. The reaction force acts on the beam in the opposite direction, and torsional torque is prevented from being added (doubled) to the beam. Therefore, an increase in the size and required strength of the beam provided with the first drive motor and the second drive motor can be suppressed.

In such a configuration, even in a configuration in which the first drive motor and the second drive motor are provided on the same beam, a mechanism for raising and lowering the corresponding lifting pallet by rotation of each drive motor is provided in a compact and simple manner. be able to.

  Moreover, it is preferable that the beam provided with the first drive motor and the second drive motor is disposed in the vicinity of the stop position above the upper lift pallet. When configured in this way, when configured in this way, the chain drawn in by the rotation of the second drive motor can be arranged in the upper space of the lower lift pallet. As a result, the arrangement space for the chain drawn in by the rotation of the second drive motor, which has been conventionally required, is reduced, and the installation space for the parking device can be reduced.
