[0016] The traction and lifting mechanism of the present invention realizes the rise and fall of the lifting platform through a steel wire rope, a lifting motor, a traction wheel and a plurality of guide wheels. Compared with the lifting method of chain and sprocket drive in the prior art, it has the characteristics of large lifting height, safety and reliability, stable and reliable operation and low noise. The steel wire rope of the present invention is divided into two directions, front and back, after winding out of the traction wheel and the second guide wheel, and the forces on both sides are balanced, which reduces the force on the traction wheel seat and avoids the disadvantage that this part is easily damaged due to excessive force. The second guide wheel is arranged in the middle position of the top of the main frame, so the required lengths of the front and rear lifting steel wire ropes are equal. Under the load condition, the extended lengths of the steel wire ropes are also equal, which avoids the possibility of the lifting platform tilting forward and backward due to the different lengths of the steel wire ropes. The central placement of the traction mechanism has a reasonable structure, and the overall force is relatively dispersed, which improves the stability of the equipment.

[0017] The lifting platform mechanism of the present invention drives the connecting piece to rotate through the reduction motor, and when the connecting piece rotates, it pulls and pushes the connecting shaft to realize the plugging and unplugging action of the plug shaft pin, thereby improving the safety of the lifting frame and preventing the occurrence of falling accidents. The lifting guide mechanism includes a support tube fixedly connected to the lifting frame, and the upper and lower ends of the support tube are respectively provided with symmetrical pulley blocks. The lifting platform is slidably connected to the main frame through the lifting guide mechanism, thereby improving the stability and stability of the lifting frame when rising and falling.

[0018] The vehicle loading plate storage and retrieval mechanism of the present invention completes the storage and retrieval operation of the vehicle loading plate by means of a hook pull pin and a fork to cooperate with the transverse movement of the vehicle loading plate. This structure is simple, low in cost, quick in operation, stable in operation, and low in failure rate, thereby improving the efficiency of storing and retrieving vehicles in the garage. The lifting frame is provided with multiple rows of lateral pulley blocks arranged in parallel, and there are three lateral pulley blocks, which are equidistantly installed on the upper surface of the lifting frame. This structure can increase the contact area with the vehicle loading plate and improve the stability and stability of the vehicle loading plate when sliding transversely.

[0050] The working process of the present invention is as follows:

[0051] Before operation, the plug pin is in the retracted state.

The double-row transmission chain continues to drive and pushes the loading plate to the lifting frame. At this time, the hook pin moves out of the fork. When the loading plate moves, the lateral pulley group supports the loading plate while reducing the friction between the loading plate and the lifting platform mechanism. The locking reduction motor rotates in the opposite direction to drive the connecting piece to rotate in the opposite direction, the connecting piece drives the connecting shaft to retract, and the connecting shaft drives the plug pin to be pulled out of the plug pin hole on the main frame.

[0052] The lateral reduction motor starts to drive the two transmission shafts to rotate synchronously, the transmission shaft drives the active sprocket to rotate, the active sprocket drives the double-row transmission chain to transmit, and the hook pin is inserted into the fork on the left side of the vehicle loading plate during rotation, and the double-row transmission chain continues to transmit to push the vehicle loading plate to the parking position, at which time the hook pin is removed from the fork. The locking reduction motor rotates in the reverse direction to drive the connecting piece to rotate in the reverse direction, the connecting piece drives the connecting shaft to retract, and the connecting shaft drives the plug-in pin to be pulled out of the plug-in pin hole on the main frame. When the lifting platform needs to be lowered, the lifting motor starts in the reverse direction to drive the transmission shaft to rotate in the reverse direction, the transmission shaft drives the traction wheel to rotate in the reverse direction, and the traction wheel releases the 8 steel ropes synchronously, at which time the lifting platform slides down smoothly and horizontally along the guide rail.
