In order to achieve the purpose of the invention, the technical scheme adopted by the invention is as follows:
the utility model provides a detection device for municipal pipeline, includes a pair of annular skeleton of joint respectively at the pipe fitting both ends that await measuring, be provided with on the annular skeleton terminal surface with the joint boss of the pipe fitting inner wall or the outer wall joint that awaits measuring, the outer anchor ring of annular skeleton all is equipped with a plurality of connecting portions that are used for fixed tensioning rope with interior anchor ring, the connecting portion of one side annular skeleton is connected through the tensioning rope with the corresponding connecting portion of opposite side annular skeleton, be connected with the probe that is used for detecting pipe fitting performance through the slider on the tensioning rope, the probe is arranged the performance that the direction detected the pipe fitting along the tensioning rope.
When the device works, firstly, the two annular frameworks are respectively arranged at the two ends of the pipe fitting to be detected, the clamping bosses of the annular frameworks are abutted against the pipe wall of the pipe fitting to be detected, then the two ends of the tensioning rope inserted with the sliding piece are respectively connected with the connecting parts at the two ends of the two annular frameworks, the tensioning rope is ensured to be parallel to the axis of the pipe fitting, and finally, a probe for detecting the quality of the pipe fitting is fixed on the sliding piece, so that the sliding piece moves along the tensioning rope, and the probe detects the quality of the pipe fitting.
In order to ensure that annular skeleton firmly joint is at the both ends of the pipe fitting that awaits measuring to ensure that the probe detects the pipe fitting quality reliably, the joint boss includes that concentric interval sets up interior joint boss and the outer joint boss on the same terminal surface of annular skeleton, interior joint boss and the pipe fitting inner wall joint that awaits measuring, outer joint boss and the pipe fitting outer wall joint that awaits measuring.
In order to ensure that the annular framework is firmly clamped at the two ends of the pipe fitting to be detected, the quality of the probe detection pipe fitting is ensured to be reliable, and the clamping boss is an annular boss.
Install on the pipe fitting of different wall thicknesses in order to guarantee annular skeleton, be equipped with a plurality of independent conflict parts on the joint boss face in opposite directions with the pipe fitting wall that awaits measuring, conflict part including setting up the guide slot on the joint boss, the guide slot in peg graft have the pressure spring, the one end of pressure spring is contradicted in the guide slot bottom, the other end overlap joint has the ball, the free end of guide slot is provided with the fender ring of restriction ball stroke.
In order to ensure that the tensioning rope is tightened and facilitate the movement of the probe along the arrangement direction of the tensioning rope, a supporting part for tightening the tensioning rope is arranged on the clamping boss.
Compared with the prior art, the invention has the beneficial effects that: because the tensioning rope cooperatees with a pair of annular skeleton respectively, again because a pair of annular skeleton cooperatees with the pipe fitting that awaits measuring to guarantee the probe and detect the pipe fitting quality along the length direction of the pipe fitting that awaits measuring, the device can detect the outer wall and the inner wall quality of certain department of pipe fitting simultaneously, thereby improves the accuracy of detecting, and this detection device is quick detachable simultaneously, and the transportation is carried.
