The driving shaft is fixedly connected to the transmission rod 38 through a flange, and a driving motor 37 is fixedly installed on the front of the reference seat 31. The output shaft of the driving motor 37 is fixedly connected to the driving shaft of the worm gear screw lift 35 located on the front through a flange. The worm gear screw lift 35 is an existing structure, and the model of the worm gear screw lift 35 can be set to JWM002-1000. Through the design of the transmission rod 38, the driving shafts of the three worm gear screw lifts 35 are connected together. The control of the driving motor 37 can drive the driving shafts of the three worm gear screw lifts 35 to rotate, and then the three screw bodies 36 can be synchronously rotated and lifted, so as to adjust the height of the lifting platform 34, so that the workers on the lifting platform 34 can weld the tops of the carriages at different heights, thereby improving the welding efficiency of the carriages.

[0028] As an implementation method in this embodiment, Figure 3 、 Figure 4 As shown, a protrusion block 321 is fixedly installed on the outer wall of the limiting cylinder 32, and the inner side of the protrusion block 321 is rotatably connected to a rotating member 322.

[0029] As an implementation method in this embodiment, Figure 1 、 Figure 2As shown, the spacing adjustment mechanism 2 includes an I-shaped base 21, which is fixedly mounted on the top of the base 1, and a sliding frame 22 is slidably connected to the outer wall of the I-shaped base 21.

The limiting bar 25 is used to limit the sliding of the sliding frame 22. After the sliding frame 22 slides to the specified position, the rotating positioning bolt 224 is rotated to cause its threaded end to close to the top of the I-type base 21, thereby completing the positioning of the sliding frame 22.

[0030] Working principle: First, clamp the bottom plate of the car on the inner side of the limit clamp 24, then hoist the side plate of the car so that the side plate of the car moves to the top of the bottom plate, then weld the bottom plate and side plate of the car, and then hoist the top plate of the car on the top of the side plate. Then the worker can move to the top of the lifting platform 34 by climbing the ladder and weld the top plate. Before welding, control the drive motor 37 to work, which can prompt the three screw rod bodies 36 to rotate and lift synchronously to adjust the height of the lifting platform 34.
