A welding quality detection device for natural gas distributed energy pipeline network

Abstract

The application relates to a welding quality detection device for natural gas distributed energy pipeline network, which belongs to the field of non-destructive detection technology of pipe welds, including a track surrounding the outer wall of the pipeline, a movable seat is slidably connected to the track, and a movable seat is installed on the movable seat. X-ray emission source, a groove is arranged on the side of the movable seat close to the track, and a driving wheel is arranged in the groove, and the driving wheel rolls on the track. The two ends of the shaft of the driving wheel are respectively connected with a telescopic rod, The other end is fixed on the inner wall of the groove, the telescopic rod is covered with a first spring, and a sliding cavity connected with the groove is also arranged in the movable seat, and an abutment plate is elastically connected in the sliding cavity, and the abutment plate is close to the drive One side of the wheel is fixed with an abutting block extending into the groove. The present application has the effect of enhancing the stability of the detection device during detection.

Description

technical field [0001] The present application relates to the field of non-destructive testing technology for welded seams of pipe fittings, in particular to a welding quality testing device for natural gas distributed energy pipeline networks. Background technique [0002] When the natural gas pipelines in the natural gas distributed energy pipeline network are in use or when laying natural gas pipelines, the weld seam inspection of the pipeline must be carried out, so as to detect the problem of weld seam leakage in time, avoid major losses, and enhance safety. [0003] At present, the Chinese utility model patent with the authorized notification number CN211697581U discloses a natural gas pipeline weld seam detection device, which includes a track and a clamp. The side edges of one end close to each other on the clamp are fixedly threaded and connected with fastening bolts. The fixed connection has rails. A movable seat is slidably connected to the track, a connecting se...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, since the end-to-end connection of the clamp is fixed, and the track is set on the clamp, there may be a seam at the end-to-end connection of the track. The inventor believes that the movable seat slides on the track through the track joint When in place, there may be bumps, affecting the stability of the detection device
