You can

However, when the turn device is mounted on the lift device, it is convenient for the turn device to support the center of the pallet at a single point in order to swing the pallet in the horizontal direction. When riding and loading the car on the lift device, or when starting the car from the pallet and leaving the car, the weight of the car acts only on one end side of the pallet, so the stability of the pallet cannot be maintained. The problem is unavoidable.

Therefore, in view of the problems of the prior art, an object of the present invention is to mount a pallet support device on both left and right sides of a turn device so that the weight of the vehicle acts only on one end side of the pallet when loading and starting the vehicle. Even if there is no possibility that the pallet will tilt, it is to provide a lift device for an underground parking device that can keep the pallet stable.

Means for Solving the Problems The structure of the present invention for achieving such an object is to provide an elevator platform for loading an automobile through a pallet, a turn device mounted on the elevator platform, and a pair of left and right units mounted on the elevator platform. The pallet support device comprises a pallet support device, the pallet support device operating at a specific height position of the lifting platform, and extending upward through the cam mechanism to support the end of the pallet on the turn device. The turning device is composed of a support body, and the gist of the turning device is to rotate the pallet when the pallet supporting device is in the inoperative state.

Action According to the configuration of the invention, the lifting platform has a pair of left and right pallet supporting devices mounted thereon, and the pallet supporting device is
It is composed of a cam mechanism that operates at a specific height position of the lifting platform, and a support body that extends upward through the cam mechanism and that supports the end portion of the pallet on the turn device. That is, the pallet support device raises and lowers the lifting platform, and when the pallet on the turn device is at the loading level on the ground surface or at a level below the loading level on the ground surface, the pallet support device moves the pallet through the support body. Both ends can be supported. Therefore, at the boarding level, even if a car is loaded onto the pallet from one end of the pallet or the car is started from one end of the pallet, there is no risk of the pallet tilting. Without, it can be kept stable enough. That is, the specific height position of the lifting platform here means the height position of the lifting platform when the pallet on the turn device is at the loading level on the ground surface or at a level below the loading level. Say.

When the pallet is lifted by driving the lifting platform to exceed the loading level on the surface of the earth, the support of the pallet support device shortens and moves away from the bottom surface of the pallet. You can
