Description
Technical Field
[0001] The utility model belongs to the technical field of flange steel pipe clamps, and more specifically, particularly relates to a steel pipe clamp used for flange welding. Background Art
[0002] Flange welding is a common method of connecting steel pipes, which uses steel flanges to fix the ends of steel pipes together. The steel pipe clamp is used to hold the steel pipe in place during flange welding, but the existing traditional clamp fixing method may not be strong enough, which may easily cause the workpiece to shake or shift during welding, affecting the welding quality. Without a separate steel pipe clamp, it is difficult to accurately position the workpiece, resulting in inaccurate welding positions. In addition, due to the lack of structural designs such as reinforced side rods, the overall rigidity of the clamp may not be strong enough, and it is easy to deform or bend, affecting the service life of the clamp, and the connection of pipes that are usually suitable for specific specifications during welding. When the pipe specifications do not match, the clamp needs to be replaced, which increases the complexity and time cost of the operation.
[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a steel pipe clamp for flange welding is provided, in order to achieve a more practical purpose. Utility Model Content

[0007] According to a further technical solution, a fastening bolt is threadedly connected to the middle of the surface of the annular clamping portion, and a terminal end of the fastening bolt is threadedly connected to the connecting base.
[0008] According to a further technical solution, a plurality of threaded through holes are arranged in an annular array on the surface of the fixed disc, and a protruding auxiliary column is welded in the middle of the surface of the fixed disc.
[0009] According to a further technical solution, a card slot is provided in the middle of the surface of the transverse card plate, and a mounting through hole is provided on the surface of the transverse card plate, and the mounting through hole can form a threaded fixed connection with the rear side clamp.
[0010] According to a further technical solution, the symmetrically arranged steel pipe clamping pieces form a steel pipe placement groove, an external steel pipe is arranged inside the steel pipe placement groove, a circular through hole is arranged on the front end surface of the steel pipe clamping piece, and an auxiliary rod is inserted into the circular through hole.
[0011] In a further technical solution, an external flange is threadedly fixed on the surface of the fixed disc, and the external flange provided on the surface of the fixed disc can be bolted via flange fixing bolts.
[0012] A further technical solution is that three sleeve placing rods are provided in a fixed array on the upper surface of the operating platform, and a large sleeve, a medium sleeve, and a small sleeve are respectively installed on the surface of the sleeve placing rods. The large sleeve, the medium sleeve, and the small sleeve can all be sleeved on the surface of the protruding auxiliary column to provide internal support for the external steel pipe.
[0013] According to a further technical solution, the box body includes a bottom box, a plurality of universal wheels are arranged in a rectangular array on the lower surface of the bottom box, a rotating base is connected to the upper surface of the bottom box, and the rotating base is fixedly connected to the lower end surface of the operating platform.
[0014] According to a further technical solution, the auxiliary rod can pass through the fixed disc and the external flange to form a connection with the steel pipe clamping plate.
[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] The surface of the fixing disc is provided with a plurality of threaded through holes, which can be threadedly fixed with the through holes of the external flange to ensure the precise positioning and alignment of the workpiece during the welding process. This is essential for the accuracy and quality of the welding operation, avoiding the deviation or instability of the workpiece, and can enhance the stability and rigidity of the steel pipe. This helps to prevent the workpiece from vibrating or deforming during the welding process, ensuring the firmness and reliability of the welded joint, and this fastening method can be achieved with non-scratch materials that will not cause damage to the workpiece surface, such as rubber gaskets or special coatings. This can effectively protect the workpiece surface from scratches, wear or other damage, ensuring the quality of the workpiece after welding.
[0017] A separate ring clamp provides stable support to ensure that the steel pipe does not move or shake during welding. This can help welders achieve higher quality weld joints, reduce the risk of welding defects caused by steel pipe movement, and welders can weld more safely without worrying about the steel pipe moving or tilting, and the ring clamp ensures that the position and angle of the steel pipe are accurate. This is especially important for welding tasks that require high precision, such as maintaining the correct position and angle of butt joints.
[0018] The auxiliary rod provided on the front side of the steel pipe clamping piece can be connected to the fixed disc and the external flange through the hole to increase the stability and rigidity of the entire system, ensuring that the clamp and the steel pipe will not loosen or deform during the welding process. This helps to ensure the quality of welding and the stability of the process. The welding process will generate stress caused by thermal stress and cooling shrinkage, which will cause the clamp and the steel pipe to deform. By using the auxiliary rod to provide additional support, the welding stress can be shared and the risk of deformation can be reduced. The auxiliary rod can effectively fix the clamp and the steel pipe, reducing the risk of accidental loosening or falling off. This is very important for the safety of the welding operator, and it also helps to ensure the quality and consistency of welding. By using the auxiliary rod, the adjustment and fixing process of the clamp can be simplified, thereby improving work efficiency. In this way, the welding operator can complete the welding task more quickly and reduce the production cycle. BRIEF DESCRIPTION OF THE DRAWINGS
