Problems solved by technology

[0003] The length of the support arm on the multi-section flaw detection machine for the existing bridge pipeline welded joints is fixed, so that only one diameter of pipeline can be used for flaw detection, and the scope of use is small. When there is an obstacle, it is impossible to pass through, which reduces work efficiency. The cameras on the multi-section flaw detection machine used for the welded joints of bridges and pipelines are all fixed by bolts, which often makes the camera appear dead angle, and cannot fully record the positional relationship between the radiation source and the weld seam, reducing the flaw detection. quality

Abstract

The invention provides a multi-joint flaw detecting and positioning device for bridge pipeline welding joints. The device comprises multi-joint telescopic rods, U-shaped mounting frames, pulleys, springs, slide rods, a stud, an electric telescoping cylinder, a moving rod, an annular gear, a rotating rod and a transmission gear. The pulleys are arranged in the U-shaped mounting frames which are arranged at outer ends of the multi-joint telescopic rods, and the springs are mounted on the slide rods which are arranged at inner ends of the pulleys. Extension length of the pulleys can be adjusted, a telescoping function is achieved, and crossing over weld joints or obstacles can be realized. The rotating rod is arranged at the right end of the moving rod which is arranged at the right end of the stud, the transmission gear is arranged at the upper end of the annular gear which is mounted on the rotating rod, and the electric telescoping cylinder is arranged at the front end of the moving rod. A camera is rotational and can be conveniently adjusted in angle. The multi-joint flaw detecting and positioning device has advantages of convenience in use, expansion of an application range, improvement of flaw detection quality and high reliability.

Description

technical field [0001] The invention relates to a multi-section flaw detection and positioning device for welded joints of bridge pipelines, which belongs to the technical field of bridge construction. Background technique [0002] A bridge refers to a building erected on rivers, lakes and seas to enable the smooth passage of vehicles and pedestrians. It is called a bridge. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head plate, conical slope protection, revetment, diversion works, etc. During the bridge construction process, it is often necessary to bury the relevant pipelines. [0003] The length of the support ...
