The sides of the lifting mechanisms are connected to lifting frames for lifting and repairing the chassis of new energy vehicles. Auxiliary stabilizing plates are set in the two lifting frames on one side. The sides of the auxiliary stabilizing plates are detachably connected to L-shaped assembly plates. The sides of the assembly plates are rotatably connected to the first push plates that facilitate the movement of the auxiliary stabilizing plates. The sides of the first push plates are rotatably connected to the second push plates.

[0009] A plurality of adjusting parts are connected between the two counterweight frames on the same side, and the side surfaces of the two adjacent transverse stabilizing plates are connected with C-shaped buckling plates for buckling and fixing.

[0033] See also Figures 1 to 4 As shown, a lifting device for repairing the chassis of a new energy vehicle, this embodiment includes:

[0034] Four counterweight frames 1, the bottom end of the counterweight frame 1 is connected to a plurality of brake casters 2, and a lateral stabilizing plate 3 is provided inside the counterweight frame 1. According to the size of the new energy vehicle chassis, the distance between the lateral stabilizing plate 3 and the counterweight frame 1 is pre-adjusted, and fixed with a fixed threaded rod 103. The sides of the two adjacent lateral stabilizing plates 3 are connected with a C-shaped snap-fit ​​plate 11 for fastening and fixing. The side of the snap-fit ​​plate 11 is constructed as an arc surface for easy fastening. Two staff members push the counterweight frames 1 on both sides to the bottom of the new energy vehicle chassis and snap the two adjacent snap-fit ​​plates 11 together;

[0035] Four lifting mechanisms 4 are respectively connected and fixed to four counterweight frames 1. The side of the lifting mechanism 4 is connected with a lifting frame 5 for lifting and repairing the chassis of the new energy vehicle. An auxiliary stabilizing plate 6 is provided in each of the two lifting frames 5 on one side. The side of the auxiliary stabilizing plate 6 is detachably connected with an L-shaped assembly plate 7. The side of the assembly plate 7 is rotatably connected with a first push plate 8 that is convenient for pushing the auxiliary stabilizing plate 6 to move. The side of the first push plate 8 is rotatably connected with a second push plate 9. The side of the lifting frame 5 is connected with a storage frame 12 for storing the assembly plate 7, the first push plate 8 and the second push plate 9. The side of the first push plate 8 is fixedly connected with a storage frame 12 for limiting the second push plate 8. The limiting plate 13 of the pushing plate 9 and the side surface of the auxiliary stabilizing plate 6 away from the second pushing plate 9 are constructed as an arc-shaped surface for easy passage. Pushing the second pushing plate 9 drives the first pushing plate 8 to move, and indirectly drives the auxiliary assembly plate 6 to be inserted into another lifting frame 5. When the first pushing plate 8, the second pushing plate 9, the assembly plate 7 and the auxiliary stabilizing plate 6 are in the same flush cross-section, under the interaction of forces, when the second pushing plate 9 is pushed, the auxiliary stabilizing plate 6 can be indirectly pushed. The limiting of the limiting plate 13 and the assembly plate 7 can ensure that the first pushing plate 8 and the second pushing plate 9 will not rotate to one side, but when rotating toward the other side, it can reduce the space occupied.

[0036] A plurality of adjusting parts 10 are connected between the two counterweight frames 1 on the same side. The adjusting parts 10 include two hollow plates 101 respectively connected to the two lifting mechanisms 4 and a movable plate 102 jointly arranged in the inner cavity of the two hollow plates 101. Threaded holes are provided on the sides of the two hollow plates 101 and the sides of the four counterweight frames 1. The threaded holes are threadedly connected with fixed threaded rods 103 for fixing. By adjusting the distance between the two counterweight frames 1 on one side in advance and fixing the movable plate 102 with the fixed threaded rods 103, the relative positions of the two lifting frames 5 and the chassis of the new energy vehicle can be changed.

[0037] The lifting mechanism 4 includes a C-shaped vertical support plate 41 and a linear motor 42 connected to the inner wall of the vertical support plate 41. The four linear motors 42 are controlled to synchronously drive the lifting frame 5 to move upward to lift the chassis of the new energy vehicle. The linear motor 42 can also be replaced with other lifting equipment with a certain load-bearing capacity, such as a hydraulic cylinder.

[0038] How it works

[0039] The lifting device for repairing the chassis of new energy vehicles pre-adjusts the distance between the lateral stabilizing plate 3 and the counterweight frame 1 according to the size of the chassis of the new energy vehicle, and fixes them with a fixed threaded rod 103. Two workers push the counterweight frames 1 on both sides to the bottom of the chassis of the new energy vehicle, fasten the two adjacent snap-fit ​​plates 11, and then push the second push plate 9 to drive the first push plate 8 to move, indirectly driving the auxiliary assembly plate 6 to insert into another lifting frame 5, adjust the distance between the two counterweight frames 1 on one side, and fix the movable plate 102 with the fixed threaded rod 103, and control the four linear motors 42 to synchronously drive the lifting frame 5 to move upward, so as to lift the chassis of the new energy vehicle.
