Opening type circular-pipe crawling detection device

Abstract

The invention relates to an opening type circular-pipe crawling detection device. The opening type circular-pipe crawling detection device comprises a driving mechanism, a track clamping mechanism and a detecting mechanism, wherein the track clamping mechanism is opening-ring-shaped, the two ends of the track clamping mechanism are respectively provided with a set of driving mechanism, and the detecting mechanism is fixed at the inner side of the track clamping mechanism; the track clamping mechanism is a circumferential and telescopic articulated structure formed by connecting rings and sleeve rings which are arranged at intervals, and the connecting rings extend into the adjacent sleeve rings and are connected with the sleeve rings by connecting ring racks; an inner rack track of the detecting mechanism is a blocking type track and is provided with a sliding clamping seat; the sliding clamping seat is in sliding connection with the inner rack track; a detecting motor drives a driving wheel which is meshed with the inner rack track; and an ultrasonic wheel type probe is arranged at the outer side of the inner rack track. The opening type circular-pipe crawling detection device has the advantages that the detection range can be changed in a freely-telescopic manner, and the quantity of the connecting rings and the quantity of the sleeve rings can be increased according to the need so as to adapt to different pipe diameters, and the pipeline can be detected comprehensively.

Description

technical field [0001] The invention relates to a detection device for corrosion defects on the outer wall of a pipeline, in particular to an open loop pipe crawling detection device. Background technique [0002] A large number of pipes are used in modern industrial and agricultural production and daily life, such as steam generator heat transfer tubes in chemical plants, industrial pipes and gas pipes in petroleum, electric power, refrigeration industries, etc. Most of the pipes are used all year round and require less maintenance. The environment cannot be directly reached by people or does not allow people to directly intervene. In order to carry out quality inspection and fault diagnosis, the traditional manual inspection method, random sampling method or SCADA system method is used, which requires a large amount of work and low accuracy. Therefore, it is necessary to develop pipeline robots to solve these practical issues. Contents of the invention [0003] The obje...
