Abstract

The invention provides a tube socket detection scanning frame and a tube socket detection scanning device. The tube socket detection scanning frame includes a main frame vehicle, a curved rod assembly and a probe fixing frame. The main frame vehicle can be mounted on the outer wall of the tube base Moving upward, one end of the curved rod assembly is connected with the main frame, and the curved rod assembly can rotate around one end of the curved rod assembly relative to the main frame, and the other end of the curved rod assembly is connected with the probe fixed frame, and the probe fixed frame can be opposite Sliding on the other end of the curved rod assembly, one end of the probe fixing frame is provided with a probe fixing base for fixing the probe. The tube seat detection scanning device containing the tube seat detection scanning frame enables the sound beam to be pointed in a certain direction stably; the detection process is semi-automatic, which reduces the influence of human factors on the detection results and can obtain good repeatability detection Results; The detection position is recorded by the encoder, and the traceability of the detection result is realized.

Description

technical field [0001] The invention relates to a device for detecting the fillet weld of a pipe seat, in particular to a pipe seat detection and scanning frame and a pipe seat detection and scanning device. Background technique [0002] The fillet weld of the pipe seat is a common structure, which is prone to stress concentration. Welding defects tend to expand during use and lead to crack failure. Therefore, it is necessary to detect the defects inside the weld during use. [0003] At present, the internal defects of the fillet weld of the pipe seat are mainly detected by ultrasonic testing. During the detection process, the probe is moved on the surface of the branch pipe or the main pipe by hand to detect the fillet weld. When the branch pipe cannot place or move the probe due to structural reasons, the probe can only be moved on the surface of the main pipe. Since the tube base is a cylindrical structure, it is difficult to ensure that the sound beam is always pointed...
