[0019] The beneficial effects of adopting the above technical solution are:

[0020] The invention has a simple structure and is driven by a reduction motor to convert the circular motion of the leveling positioning gear into the linear motion of the leveling positioning rack. The leveling positioning rack transmits power to the leveling positioning telescopic plate, and a roller is installed at the end of the leveling positioning telescopic plate, so that the roller at the end of the leveling positioning telescopic plate fits with the leveling positioning block, thereby playing a leveling positioning role. The roller reduces the resistance between the leveling positioning telescopic plate and the leveling positioning block, and the leveling positioning telescopic plate is more easily fitted with the inclined surface of the V-shaped groove on the leveling positioning block. The V-shaped groove plays the function of automatically correcting the height, thereby ensuring the accuracy of the leveling positioning. The gear rack structure ensures the synchronization of the operation of the leveling positioning telescopic plates on both sides of the elevator, and the structure has a large output torque and runs smoothly. The noise generated when the vehicle loading plate is running due to inaccurate leveling positioning of the elevator is reduced. The original traditional action of "elevator slightly rises-telescopic rod opens-elevator falls" is changed to "telescopic rod opens-leveling height automatic correction", thereby shortening the time for picking up the vehicle.

[0021] The locking hook in the vehicle plate locking hook mechanism uses a tensioning spring to lock the hook, and the hook hooks the hook fixing shaft on the vehicle loading plate to achieve the function of locking the vehicle loading plate. The locking plate is designed as a vertical steel plate, which increases the contact area between the vehicle plate locking telescopic plate and the locking plate, ensuring that it is not affected by the height during the leveling positioning. The vehicle plate locking device adopts a gear rack to ensure the stability of the equipment operation, and the leveling positioning device and the vehicle plate locking device adopt a driving linkage device to achieve linkage control, ensuring that after the elevator is leveled and positioned, the vehicle plate locking device is also in the open state at the same time, and the vehicle loading plate can be smoothly picked up by the picking device, ensuring the safe operation of the equipment.

[0022] The picking device picks up the carrier plate through a sprocket chain, a picking pin is arranged on the picking chain, and a corresponding picking block is designed on the carrier plate, thereby realizing the picking function of the carrier plate. The picking devices on both sides of the lifting frame realize synchronous operation through the transmission shaft five and the universal coupling, and realize the precise positioning function of the carrier plate through the absolute encoder.

[0023] In addition, the rope pulley device adopts the movable pulley principle, and the output torque of the servo motor is saved by one time. BRIEF DESCRIPTION OF THE DRAWINGS
