Embodiment 1

[0028] refer to Figure 1-5 , a weld detection device for pipeline welding, comprising a base 1, the upper surface of the base 1 is provided with a support frame 21 in an arcuate structure near both ends, and the opposite sides of the vertical columns on both sides of the two support frames 21 are respectively C-shaped steel columns 10 with openings opposite to each other are provided, and slide blocks 6 are provided in the slide grooves of the two C-shaped steel columns 10 near both ends, and the two sliders in the same C-shaped steel column 10 are rotatably connected with The same two-way screw 501, the surface of the two sliders 6 in the same C-shaped steel column 10 is fixed with two mutually symmetrical clamping blocks 7, and the opposite side of the clamping blocks 7 is reserved with the outer diameter of the welded pipe body 8 A matching arc surface, and the arc surface is clamped with balls 9 equidistantly distributed, the bottom end of the two-way screw 501 is fixed w...

Embodiment 2

[0036] refer to Figure 1-3 , a weld detection device for pipeline welding. Compared with Embodiment 1, this embodiment also includes a mounting hole 101 in the middle of the upper surface of the base 1, and a hydraulic ejector rod 20 is clamped in the mounting hole 101, and the hydraulic ejector The top end of the rod 20 is fixed with a supporting plate 19 by bolts.

[0037] Wherein, the upper surface of the supporting plate 19 is provided with limiting clamping plates 2 close to both ends, and the upper surface of the limiting clamping plates 2 is provided with arc-shaped limiting grooves.

[0038]Wherein, the inner wall of the arc-shaped limiting groove is provided with grooves distributed equidistantly, and balls 201 are embedded in the grooves.

[0039] Working principle: When in use, put the welded pipe body 8 on top of the two limit clamps 2, and then slowly push it until the other end of the limit clamp 2 enters the clamping range of the next set of clamping blocks 7 ...

Abstract

The invention belongs to the technical field of pipeline weld joint detection, in particular relates to a weld joint detection device for pipeline welding. Aiming at the problems that an existing flawdetector needs to be held by hands to detect the S-shaped weld joints on a pipeline in the detection process, and the labor intensity is high, the weld joint detection device according to the schemecomprises a base, supporting frames of arch structures are arranged at the positions, close to the two ends, of the upper surface of the base, C-shaped steel stand columns with opposite openings are arranged at the opposite sides, perpendicular to stand columns, of the two sides of the two supporting frames respectively, and sliding blocks are slidably connected to the positions, close to the twoends, in the sliding grooves of the two C-shaped steel stand columns. When the weld joint detection device is used, and a welding pipe body needs to be clamped, the four clamping blocks can slowly move towards the middle only by rotating the two two-way screws in the same direction till the first balls on the arc-shaped faces make contact with the outer wall of the welded pipe body, and at the moment, the flaw detector can walk along the weld joint by rotating the welded pipe body and pushing the welded pipe body forwards at the same time.

Description

technical field [0001] The invention relates to the technical field of pipeline weld detection, in particular to a weld detection device for pipeline welding. Background technique [0002] The weld detector is a portable ultrasonic weld defect detector, which can quickly, conveniently, non-destructively and accurately detect and locate various defects (cracks, inclusions, pores, incomplete penetration, incomplete fusion, etc.) inside the workpiece , assessment and diagnosis. It is not only used in the laboratory, but also used in engineering field testing. It is widely used in weld detection in boiler and pressure vessel manufacturing, weld quality assessment in construction machinery manufacturing, iron and steel metallurgy, steel structure manufacturing, shipbuilding, oil and gas equipment manufacturing and other fields that require defect detection and quality control. [0003] When the detector on the weld detector detects the weld on the steel structure, when it is ne...
