Pipeline defect ultrasonic detection device

Abstract

A pipeline defect ultrasonic detection device provided by the present invention comprises an ultrasonic detection device main body, an auxiliary detection device and a detection head, the auxiliary detection device comprises a mounting seat and a rubber sheath, and the rubber sheath is fixedly mounted at the bottom of the mounting seat. The pipeline defect ultrasonic detection device is reasonable in design, a plurality of left convex linkage rods and a plurality of right convex linkage rods are mounted at the bottom of the mounting seat of the auxiliary detection device, the left convex linkage rods and the right convex linkage rods are connected with the left convex linkage rods and the right convex linkage rods, and the left convex linkage rods and the right convex linkage rods are connected with the left convex linkage rods and the right convex linkage rods through the left convex linkage rods and the right convex linkage rods. During detection, in the process that the auxiliary detection device is attached to the surface of a pipeline, the left convex linkage rods and the right convex linkage rods can be attached to the surface of the pipeline in a self-adaptive mode, and the rubber leather sheath is stretched and shaped at the same time, so that the detected position and the detection head are completely isolated from the outside, external sound waves are prevented from influencing detection, and the detection accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection equipment production, in particular to an ultrasonic detection device for pipeline defects. Background technique [0002] During the long-term use of the pipeline, defects such as cracks may occur, which need to be inspected for maintenance. It is difficult to find defects inside the pipeline. Ultrasonic testing is an effective method. When testing, it is necessary to avoid external The interference of sound waves, so as not to affect the accuracy of detection, and the surface of the pipe is curved, the detection head cannot be completely attached to the pipe, and the detection head needs to be perpendicular to the pipe to ensure the accuracy of detection. It is difficult to hold the detection head However, the existing ultrasonic detection device for pipeline defects cannot solve the above problems, and the detection accuracy can be further improved. Therefore, the present invention pr...
