Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a steel structure welding fixture. Background Art

[0002] In order to fix and connect two sections of steel structure, or in the process of repairing and renovating steel structure in the case of pipeline leakage, welding is usually required. The patent with publication number "CN221159458U" and titled "A Steel Pipe Clamp" discloses a two-arc clamp that wraps the steel pipe. Although it can increase the contact area with the steel pipe, this solution places the steel pipe on the lower arc clamp, and then gradually moves the upper arc clamp closer to the lower arc clamp to clamp the steel pipe. However, this mechanism can only move the upper clamp and cannot move and adjust the lower clamp. The function is single, which leads to the use limitations of the steel pipe welding clamp equipment.

[0005] A support, wherein the clamping mechanism is connected to the support and is symmetrically arranged along the center line of the support;

[0006] The clamping mechanism includes a splint, a screw, a connecting rod, a crank and a through hole. The crank is arranged on the outer wall of the support, and the crank is connected to the screw. The end of the screw is connected to the splint. When the crank rotates, it drives the screw to rotate, and the screw gradually moves to drive the splint to move. Two placement grooves are respectively provided on the side walls at both ends of the support for placing the steel structure.

[0007] Furthermore, the clamping plate is an L-shaped clamping plate for clamping square steel pipes.

[0008] Furthermore, the clamping plate is an arc-shaped clamping plate for clamping a circular steel pipe.

[0009] Furthermore, connecting rods parallel to the lead screw are provided on the left and right sides of the lead screw, one end of the connecting rod is detachably connected to the splint, and the other end of the connecting rod passes through a through hole opened on the support, driving the connecting rod to move when the lead screw moves.

[0010] The above technical solution has the following beneficial effects:

[0011] The utility model is symmetrically provided with a clamping mechanism on both sides of the support. The clamping mechanism includes a clamping plate, a screw, a connecting rod, a crank, and a through hole. The clamping plate is driven to move by the cooperation of the clamping plate, the screw, the connecting rod, the crank, etc., and the two clamping plates are driven to move relative to each other and close together, thereby clamping the steel structure. When clamping is not required, the crank of one of the clamping mechanisms is rotated in the opposite direction, and the screw moves outward, thereby removing the steel structure from above the clamping plate. The two clamping mechanisms of the utility model are both movable and adjustable, and the steel structure can be placed in the groove of the bracket without the need for hand-holding. The placement groove is provided with two or even multiple coaxially arranged slots, so that the steel structure is not easily tipped over, thereby improving the stability of the steel structure placement.
