The middle-size and small-size vehicle multilayer lifting work of this perpendicular elevating gear of self-adjusting:
the lifting mechanism 22 drives the carrier plate 3 of the first layer 101 to lift between the first layer 101, the second layer 102 and the other layers 103, and the lifting mechanism 22 drives the carrier plate 3 of the second layer 102 to lift between the first layer 101 and the second layer 102.
When the middle-small vehicle carries out multi-layer lifting operation on the first layer 101, the second layer 102 and the other layers 103 of the platform model 1, the lifting mechanism 22 drives the corresponding carrier plate 3 to move up and down, so that the carrier plate 3 is aligned with the moving slope 8, and then a driver can drive the middle-small vehicle to directly climb into the carrier plate 3 through the moving slope 8.
After the driver drives the small and medium-sized vehicle to mount the carrier plate 3, when one side wheel of the small and medium-sized vehicle is pressed on the rear pressure sensor 31 on the carrier plate 3, the rear pressure sensor 31 is triggered, and meanwhile, the other side wheel of the small and medium-sized vehicle is pressed on the front pressure sensor 53 of the guide plate 52, the front pressure sensor 53 is triggered, and then the carrier plate 3 is driven by the lifting mechanism 22 to move up and down, so that the carrier plate 3 is lifted and moved into the second layer 102 or the other layers 103.
When the small and medium-sized vehicles on the carrier plate 3 enter other layers 103 and need to leave the carrier plate 3, the telescopic ends of the electric push rods 41 actively push the guardrails 4, so that the guardrails 4 are turned backwards around the axes of the rotating shafts connected with the other carrier plates 3, the guardrails 4 are turned backwards and downwards to be in a transverse state, and a driver can smoothly drive the small and medium-sized vehicles to press the guardrails 4 to leave the carrier plate 3 and drive the small and medium-sized vehicles into other layers 103.
The middle-large-sized vehicle multilayer lifting work of the self-adjusting vertical lifting device:
in order to save the occupied space of the self-adjusting vertical lifting device, the length of the carrier plate 3 is defaulted to be suitable for medium and small-sized vehicles, and when the carrier plate 3 needs to lift the medium and large-sized vehicles, the default length of the carrier plate 3 is not used for the medium and large-sized vehicles.
Firstly, the lifting mechanism 22 drives the carrier plate 3 to move up and down, the carrier plate 3 is aligned with the moving slope 8, then a driver drives a middle-large vehicle to directly ascend into the carrier plate 3 through the moving slope 8, when one side wheel of the middle-large vehicle is pressed on the rear pressure sensor 31 on the carrier plate 3, the rear pressure sensor 31 is triggered, the other side wheel of the middle-large vehicle is positioned forwards and is not successfully pressed on the front pressure sensor 53 of the guide plate 52, the front pressure sensor 53 is not triggered, the electric control screw 62 actively drives the sliding connection block 61 to move forwards, the sliding connection block 61 pushes the guide slide block 51 and the guide plate 52 to move forwards through the connecting rod 63, meanwhile, the telescopic end of the electric control hydraulic cylinder 81 pulls the moving slope 8 to move forwards along with the guide plate 52, and the guide plate 52 drives the wheel contacted by the wheel to rotate, so that the vehicle keeps static relative to the carrier plate 3 until the other side wheel of the middle-large vehicle is smoothly pressed on the front pressure sensor 53 of the guide plate 52, so that the front pressure sensor 53 is triggered, and the active adaptation of the middle-large vehicle is realized.
Then the lifting mechanism 22 drives the carrier plate 3 to lift the middle and large vehicle, at this time, wheels on two sides of the middle and large vehicle are respectively positioned in the concave structures of the rear pressure sensor 31 and the front pressure sensor 53, and the center of gravity of the whole middle and large vehicle is positioned in the middle area between the carrier plate 3 and the guide plate 52, so that the middle and large vehicle is stably parked on the carrier plate 3, and the phenomenon that the middle and large vehicle slides forward due to the fact that the center of gravity is forward or violent shake generated when the carrier plate 3 is lifted is avoided in the lifting process of the carrier plate 3 driven by the lifting mechanism 22.

When the vehicle on the carrier plate 3 enters the other layer 103 and needs to leave the carrier plate 3, the electromagnet 47 actively and magnetically attracts the buffer plate 44 close to the guardrail 4, the telescopic end of the electric push rod 41 actively pushes the guardrail 4 to turn backwards, the guardrail 4 is turned backwards down, a driver can smoothly drive a small and medium-sized vehicle to press the guardrail 4 to leave the carrier plate 3 and drive the carrier plate 3 into the other layer 103, and at the moment, the buffer plate 44 actively and magnetically attracted by the electromagnet 47 is lower than the chassis height of the vehicle, so that the vehicle can leave the carrier plate 3 without being blocked by the buffer plate 44.
