[0034] When in use, the front wheel pushing positioning device 102 and the rear wheel pushing positioning device 103 work synchronously to center the left and right directions of the vehicle body. When working, the front wheel pushing positioning device 102 and the rear wheel pushing positioning device 103 work synchronously. At this time, the pushing cylinder 112 works to extend its telescopic end, and the pushing cylinder 112 pushes the sliding plate 108 to drive the nylon push plate 111 to move.

[0049] The lifting platform 3 includes a base 303 , which is fixedly mounted on the traveling frame 203 . A lifting platform 301 is disposed above the base 303 , and a lifting driving component is disposed between the lifting platform 301 and the base 303 .

[0050] The lifting drive assembly is used to drive the lifting platform 301 to move upward or downward, so as to adjust the height position of the lifting platform 301.

[0051] The lifting drive assembly includes two sets of scissor fork frames 302 , and the two sets of scissor fork frames 302 are arranged in parallel and at intervals.

When the belt take-up shaft 307 rewinds the belt, the belt drives the belt shaft 306 to move toward the side close to the belt take-up shaft 307. At this time, the two connecting rods 308 of the scissors fork frame 302 rotate around the hinge shaft, thereby driving the lifting platform 301 to move upward.

[0056] When the belt take-up shaft 307 unwinds the belt, the gravity on the lifting platform 301 acts on the scissor fork frame 302, causing the two connecting rods 308 of the scissor fork frame 302 to rotate around the hinge axis, thereby moving the belt shaft 306 to the side away from the belt take-up shaft 307, causing the lifting platform 301 to move downward.

[0066] When the adjustable lifting assembly needs to be installed on the mounting frame 402 , the support cross bar 404 and the hinged support seat 408 are both fixedly installed on the mounting frame 402 .

[0067] When in use, the initial state is: the telescopic end of the swing cylinder 407 is in a retracted state, at this time, the telescopic end of the swing cylinder 407 drives the corresponding articulated arm 405 to rotate along the hinge between the articulated arm 405 and the supporting cross bar 404, so that the articulated arms 405 at both ends of the supporting cross bar 404 are arranged in parallel. At this time, the maximum distance between the two support blocks 406 is smaller than the width of the lifting platform 301.

[0068] When the vehicle body needs to be lifted, the telescopic end of the swing cylinder 407 is extended. At this time, the telescopic end of the swing cylinder 407 drives the corresponding articulated arm 405 to rotate along the hinge between the articulated arm 405 and the supporting cross bar 404, so that the articulated arms 405 at both ends of the supporting cross bar 404 are coaxially arranged. At this time, the maximum distance between the two support blocks 406 is greater than the width of the lifting platform 301.

[0071] The driving screw 410 is threadedly connected with a driving nut, and the driving nut is fixedly installed below the T-shaped frame 401 .

[0072] With this design, the servo motor 409 is used to drive the driving screw 410 to rotate. The driving screw 410 is threadedly connected to the driving nut, and then the T-shaped frame 401 can be driven to move on the second slide rail 403 through the driving nut, thereby adjusting the distance between the two adjustable lifting components for easy use.

[0073] When in use, the fully automatic distance-adjustable walking lifting vehicle transfer device can perform vehicle transfer actions and vehicle transfer actions.

[0074] When the vehicle delivery action is executed, the vehicle body to be transported is transported to the area of ​​the straightening and centering device 1. At this time, the two front wheels of the vehicle body are located on the front wheel positioning rollers 105 on the two support plates 101. The front wheel positioning rollers 105 can be used to position the front and rear positions of the vehicle body, thereby achieving a preliminary limitation of the front and rear positions of the vehicle body; the front wheel positioning rollers 105 and the rear wheel positioning rollers 106 cooperate to support the vehicle body to move left and right, and the front wheel pushing positioning device 102 and the rear wheel pushing positioning device 103 work synchronously to make the nylon push plate 111 contact with the front and rear wheels of the corresponding vehicle body, thereby pushing the vehicle body to move left and right, thereby achieving a center positioning of the left and right directions of the vehicle body, thereby completing the positioning work before the vehicle body is transported, which is convenient for use.

[0075] Then, the automatic distance-adjusting support mechanism 4 adjusts the distance between the two adjustable lifting assemblies front and back according to the type of the vehicle body to be transported. The servo motor 409 in the servo drive device is used to drive the driving screw 410 to rotate. The driving screw 410 rotates through the driving nut to drive the T-shaped frame 401 to move on the second slide rail 403, thereby adjusting the distance between the two adjustable lifting assemblies for easy use.

[0076] After the distance between the two adjustable lifting assemblies is adjusted, the telescopic end of the swing cylinder 407 of the adjustable lifting assembly extends out to drive the corresponding articulated arm 405 to rotate, so that the articulated arms 405 at both ends of the supporting cross bar 404 are coaxially arranged. At this time, the maximum distance between the two support blocks 406 is greater than the width of the lifting platform 301, thereby making the two support blocks 406 reach the desired position.

[0077] Then the driving assembly 304 of the lifting platform 3 is used to drive the scissor fork frame 302 to work, and the scissor fork frame 302 drives the lifting platform 301 to move up and down. When the lifting platform 301 moves up, the supporting block 406 contacts the corresponding top contact position on the vehicle body chassis. The lifting platform 301 continues to rise to lift the vehicle body, so that the wheels of the vehicle body rise and move away from the straightening and centering device 1.

[0078] Then the reciprocating device 2 works to move the traveling frame 203, thereby driving the lifting platform 3 to move, so as to transport the vehicle body forward to the elevator area. The lifting platform 3 continues to work to drive the vehicle body to the height of the hoisting device position, the hoist is closed, and the lifting platform 3 descends to a certain height to achieve the separation of the whole vehicle and the automatic distance adjustment support mechanism 4, and then the swing cylinder 407 performs the resetting work to reset each support block 406; the lifting platform 3 continues to descend to the low position, and the reciprocating device 2 is activated to make the lifting platform 3 return to the area of ​​the straightening and centering device 1. This process realizes the vehicle delivery action of the whole vehicle.

[0079] When the vehicle receiving action is executed, the whole vehicle is transported to the lower position of the elevator through the lifting device driven by the elevator. At this time, the lifting platform 3 is parked at the bottom of the elevator area, and the swing cylinder 407 and the support block 406 are in the initial position state; then the lifting platform 3 works to drive the automatic distance adjustment support mechanism 4 to rise to a height position a certain distance away from the whole vehicle, and the automatic distance adjustment support mechanism 4 adjusts the distance between the two adjustable lifting components front and back according to the vehicle model. After the adjustment is completed, the swing cylinder 407 works to drive the support block 406 to swing to the required position; then the lifting platform 3 continues to rise, so that the whole vehicle and the support block 406 of the automatic distance adjustment support mechanism 4 are in contact and lifted up a certain distance, and then the lifting device is opened, so that the whole vehicle is stably placed on the automatic distance adjustment support mechanism 4.

[0080] Then the lifting platform 3 drives the whole vehicle to descend to the middle position, and the reciprocating movement device 2 works to drive the lifting platform 3 to move, so that the whole vehicle is transported out of the elevator area to the lower part area of ​​the straightening and centering device 1, and the lifting platform 3 drives the whole vehicle to continue to descend, so that the tires of the whole vehicle contact the support plate 101 in the straightening and centering device 1, and then the lifting platform 3 continues to descend, so that the whole vehicle and the automatic distance adjustment support mechanism 4 are separated, and then the swing cylinder 407 performs the resetting work to reset each support block 406; then the reciprocating movement device 2 works to drive the lifting platform 3 to return to the bottom area of ​​the elevator. This process completes the vehicle receiving action.

[0081] For those skilled in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
