[0002] In welding operations, especially in the welding process of large structural parts, welding personnel and equipment need to work on a higher platform. The scissor structure of the traditional welding lifting platform is composed of multiple parts, and the parts are loosely connected. Therefore, the lifting platform often swings greatly during use, which directly affects the welding quality and threatens the safety of people and machines. Utility Model Content

[0003] In view of the above problems, the utility model aims to provide a lifting platform for anti-swing welding.

[0004] The technical solution of the utility model is: the utility model is a lifting platform for anti-swing welding, including a top cover and a base connected to each other, a plurality of groups of scissor structures are arranged between the top cover and the base, and the top cover and the base together form a lifting platform through the arranged plurality of groups of scissor structures.

[0005] Furthermore, the scissor structure includes an inner frame and an outer frame, and the inner frame and the outer frame are movably connected via a through-arranged knob;

[0006] The positions of the holes for inserting the knobs on the inner frame and the outer frame are matched.

[0007] Furthermore, one side of the inner frame and the outer frame arranged at the bottom is movably connected to the side walls of the base via the arranged knobs;

[0008] One side of the inner frame and the outer frame arranged at the top is movably connected to the side walls of the top cover via the arranged knobs;

[0009] The holes provided at one side of the inner frame and the outer frame at the bottom are matched with the positions of the holes provided at the side walls of the base;

[0010] The holes arranged at one side of the inner frame and the outer frame at the top are matched with the positions where the holes are opened on the side wall of the top cover.

[0011] Furthermore, the inner frame and the outer frame are both an integrated rigid frame, and the cross-sectional shapes of the four arms constituting the rigid frame are different.

[0012] The four arms making up the rigid frame are of different lengths.

[0013] Furthermore, one or more power units are arranged on the scissor structure, and the power units are composed of one or more hydraulic cylinders.

[0014] Furthermore, the volumes of the top cover and the base are equal, and the outer diameter of the scissor structure is smaller than the inner diameters of the top cover and the base.

[0015] Furthermore, the number of groups of the inner frame and the outer frame is at least 5;

[0016] The outer diameter of the inner frame is smaller than the inner diameter of the outer frame.

[0017] The beneficial effects of the utility model are: 1. The inner frame and the outer frame constituting the scissor structure are both composed of a four-arm integrated rigid structure, and the single frame itself has anti-swing characteristics; 2. Since the inner frame and the outer frame are an integrated rigid structure, a very small gap can be achieved between the inner frame and the outer frame, and the frames are anti-swing; 3. Since the anti-swing principle of the elevator does not rely on a bulky frame, the volume of the elevator in the retracted state is smaller. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific technical scheme of the utility model is further described in detail below with reference to specific examples.

[0026] As shown in the figure, the anti-swing welding lifting platform described in the utility model includes a top cover 1 and a base 2, and the top cover 1 and the base 2 are connected by a plurality of scissor structures;

[0027] Furthermore, the scissor structure is composed of an inner frame 3 and an outer frame 4, and the inner frame 3 and the outer frame 4 are both integral rigid frames.

[0028] Furthermore, the cross-sectional shapes of the four arms constituting the rigid frame are not completely the same.

[0029] Furthermore, the four arms constituting the rigid frame are not completely equal in length.

[0030] Furthermore, one or more power parts 5 are arranged on the scissor structure.

[0031] Furthermore, the power unit 5 is composed of one or more hydraulic cylinders.

[0032] The steps of using the utility model are explained as follows: when raising the platform, the cylinder of the power unit 5 rebounds, driving the bearing element inside the base 2 to slide, and at the same time the inner frame 3 in the scissor-type structure connected to the bearing shaft begins to move upward, and the outer frame 4 and the inner frame 3 in the remaining scissor-type structure begin to cooperate with each other, and the lifting platform is adjusted to a suitable welding position for welding, at which time the power unit 5 is automatically locked; when lowering the platform, the cylinder of the power unit 5 contracts, and the outer frame 4 and the inner frame 3 in the scissor-type structure move simultaneously in a direction parallel to the ground, so that the top cover 1 and the base 2 can be closed without a gap.
