[0002] Due to the advantages of high strength, light self-weight, and convenient construction, steel structures are widely used in many fields such as buildings, bridges, and industrial factories. Welding, as a key process for steel structure connection, its quality is directly related to the overall stability and safety of the steel structure. During the welding process, in order to ensure the precise alignment of the welding parts and the smooth progress of the welding operation, welding stability, positioning, and clamping equipment play a crucial role.

[0003] At present, most steel structure projects adopt the construction method of factory prefabrication and on-site welding. After each beam and column component is hoisted to the designated position on-site by a tower crane, it is positioned by construction workers, and then the construction workers hold an electric welding gun to weld the connection. During welding, the workpiece is easily displaced or deformed due to heat deformation and welding stress. During the welding process, adjustment cannot be carried out in a timely manner, resulting in low welding stability and prone to the phenomenon of insecure welding. Summary of the Invention

[0023] Embodiment

[0024] A steel structure butt welding adjustment device includes a main control body 1. The left wing connection block 2 and the right wing connection block 3 are rotatably connected to both sides of the main control body 1. Hydraulic fixed shells 4 are provided on the opposite surfaces of the left wing connection block 2 and the right wing connection block 3. A transverse hydraulic telescopic rod 6 is provided inside the hydraulic fixed shell 4. The output end of the transverse hydraulic telescopic rod 6 is fixedly connected to a longitudinal connection structure 5. A liquid crystal control panel 7 is provided on the upper surface of the main control body 1. The left wing connection block 2 and the right wing connection block 3 are used to fix the steel structure already fixed on the main beam, so that the left wing connection block 2 and the right wing connection block 3 wrap and hold the steel structure. Then, through the transverse hydraulic telescopic rod 6, the longitudinal connection structure 5 is extended towards the steel structure to be butt welded, and the longitudinal connection structure 5 is used to fix the position of the steel structure on the other side. During the welding process, the transverse hydraulic telescopic rod 6 can be used to adjust the distance between the butt joints of the two steel structures to ensure that the distance between them does not change during welding. And during welding, the upper surface and the lower surface of the butt joint of the steel structure can be welded first, and then the transverse hydraulic telescopic rods 6 on the left wing connection block 2 or the right wing connection block 3 are extended and retracted in turn to expose the welding position on one side, ensuring that there is an external force supporting the steel structure at all times during welding, effectively avoiding deformation during the welding process.

[0025] The left wing connection block 2 includes a side column 21. A semi-base 22 is provided below the side column 21. The semi-bases 22 on the left wing connection block 2 and the right wing connection block 3 can be closed to clamp and fix the steel structure between the semi-bases 22 to ensure stability. The side column 21 and the semi-base 22 are integrally cast, and the overall stability of the integral casting is higher. A number of ball shaft holes 23 are provided on the side surface of the side column 21. The side column 21 is symmetrically provided with sliding grooves 24. A connecting seat 25 is slidably connected in the sliding grooves 24. An electromagnetic slide rail 26 is embedded on the side column 21. The slider of the electromagnetic slide rail 26 is fixedly connected to the hydraulic fixed shell 4. The height of the hydraulic fixed shell 4 can be adjusted through the electromagnetic slide rail 26, which is convenient for adjustment according to the groove position of the steel structure, and has a wider application range.

[0026] The main control body 1 includes a box body 11. Ball shafts 12 are provided on the surfaces of the box body 11 opposite to the left wing connection block 2 and the right wing connection block 3. Hydraulic telescopic rods 13 are symmetrically provided on the side surface of the box body 11. The output ends of the hydraulic telescopic rods 13 are fixedly provided with connecting blocks 14. As the hydraulic telescopic rods 13 extend, the connecting seat 25 will be driven to move, and the left wing connection block 2 will be driven to expand, which is convenient for the user to use from above the steel structure, improving safety and the convenience of use. Similarly, when the hydraulic telescopic rods 13 on the right wing connection block 3 extend, the right wing connection block 3 will also be driven to expand. When the hydraulic telescopic rods 13 contract, the left wing connection block 2 and the right wing connection block 3 will be driven to close to clamp the steel structure.

[0027] The longitudinal connection structure 5 includes a longitudinal hydraulic telescopic rod 51. A rubber layer 52 is provided on the longitudinal hydraulic telescopic rod 51. The longitudinal hydraulic telescopic rods 51 are symmetrically arranged on the upper and lower surfaces of the longitudinal connection structure 5. The longitudinal hydraulic telescopic rods 51 will enter the grooves of the butt-jointed steel structure, and the steel structure is fixed by the longitudinal hydraulic telescopic rods 51.

[0028] The left-wing connection block 2 and the right-wing connection block 3 have the same structure. The longitudinal hydraulic telescopic rods 51 on the left-wing connection block 2 and the longitudinal hydraulic telescopic rods 51 on the right-wing connection block 3 can be selected to synchronously expand and contract or expand and contract on one side alone through the liquid crystal control panel 7. Taking the longitudinal hydraulic telescopic rod 51 on the left-wing connection block 2 as an example, the longitudinal hydraulic telescopic rods 51 are arranged on the upper and lower surfaces of the longitudinal connection structure 5, so there are two longitudinal hydraulic telescopic rods 51 on both sides, temporarily called the first side (upper surface) and the second side (lower surface). The longitudinal hydraulic telescopic rods 51 on the first side and the second side can expand and contract synchronously on both sides and with the longitudinal hydraulic telescopic rods 51 on the right-wing connection block 3, or the longitudinal hydraulic telescopic rods 51 on the first side can be expanded and contracted alone or the longitudinal hydraulic telescopic rods 51 on the second side can be expanded and contracted alone. Similarly, the longitudinal hydraulic telescopic rods 51 on the right-wing connection block 3 can also perform the same operations through the liquid crystal control panel 7. The longitudinal hydraulic telescopic rods 51 on the four sides can be expanded and contracted synchronously or alone. By controlling the expansion and contraction of the longitudinal hydraulic telescopic rods 51 on the four sides, the fixation of the steel structure and the left-right height fine adjustment can be achieved.

[0029] The connecting block 14 is connected to the connecting seat 25 by a pin connection, and the ball shaft 12 is rotatably connected to the ball shaft hole 23, which facilitates the rotation of the left-wing connection block 2 and the right-wing connection block 3 relative to the main control body 1 to achieve the clamping action.

[0030] A control circuit, a power supply and a CPU processing center are provided inside the main control body 1. A power charging port is provided on the side surface of the main control body 1. The hydraulic telescopic rod 13, the transverse hydraulic telescopic rod 6, the electromagnetic slide rail 26 and the longitudinal hydraulic telescopic rod 51 are all electrically connected to the control circuit for easy control.

[0031] Working principle:

[0032] Start the hydraulic telescopic rod 13 through the liquid crystal control panel 7 to extend the hydraulic telescopic rod 13, drive the left wing connecting block 2 and the right wing connecting block 3 to unfold. After unfolding, horizontally place the main control body 1 on the steel structure that has been fixed to the main beam. Then start the hydraulic telescopic rod 13 through the liquid crystal control panel 7 to contract the hydraulic telescopic rod 13 until the semi-base 22 is located below the steel structure and clamps the steel structure stably to complete the fixation of the fixed end of the steel structure. During the fixation process, the electromagnetic slide rail 26 can be started to adjust the position of the hydraulic fixing housing 4 to ensure that the hydraulic fixing housing 4 is located in the groove of the steel structure. Then start the horizontal hydraulic telescopic rod 6 through the liquid crystal control panel 7 to extend the horizontal hydraulic telescopic rod 6, insert the longitudinal connection structure 5 into the groove of the steel structure to be docked, and then synchronously start the longitudinal hydraulic telescopic rods 51 on the four sides to fix and support the steel structure. After completion, the horizontal hydraulic telescopic rod 6 contracts to dock the two steel structures. After the docking position is determined, first weld the upper surface and the lower surface of the docking part, and then sequentially extend and contract the horizontal hydraulic telescopic rod 6 on the left wing connecting block 2 or the right wing connecting block 3 to expose the welding position on one side and weld the position on the side of the docking part. Ensure that during the welding process, there is always a longitudinal hydraulic telescopic rod 51 on one side that has a supporting force on the steel structure to ensure the fixation of the position during the welding process. When welding the upper and lower two surfaces, if the docking surfaces are uneven in height, the left and right height can be adjusted by separately controlling the longitudinal hydraulic telescopic rods 51 on each surface to ensure the flatness of the welding surface.

[0033] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
