Detection device for acetylene gas supply connecting pipeline

The utility model discloses a detection device for an acetylene gas supply connecting pipeline, which comprises a hollow cylinder sleeved on the pipeline and provided with passages at two ends, and a plurality of self-propelled mechanisms and detection mechanisms are mounted on the inner wall of the cylinder in an annular array manner. The self-walking mechanism abuts against the surface of the pipeline and drives the whole device to move in a self-walking mode. The self-walking mechanism adapts to different pipe diameters through a self-adaption assembly and abuts against the pipe diameters. According to the technology provided by the utility model, a pipeline system can be fully covered through an automatic device, and continuous monitoring can be carried out to ensure that any potential leakage point cannot be missed. Therefore, the comprehensiveness and continuity of detection are improved, and compared with the traditional manual inspection, the problem is not easy to miss. According to the acetylene lea
