Abstract

The invention discloses an inner diameter detection device, which belongs to the technical field of machinery. The inner diameter detection device comprises a main body cylinder, and a steel brush assembly, a geometric probe assembly and an odometer assembly located on the outer wall of the main body cylinder, wherein the steel brush assembly is used for supporting the inner wall of a to-be-detected pipeline, the geometric probe assembly is used for detecting the inner diameter of the to-be-detected pipeline, and the odometer assembly is used for detecting the moving distance of the inner diameter detection device in the to-be-detected pipeline. The device solves the problem that the accuracy of the inner diameter of the pipeline detected by the geometric probe is affected due to the factthat the whole inner diameter detection device vibrates when the inner diameter detection device passes through the circumferential weld of the pipeline in the prior art, and is used for detecting theinner diameter of the pipeline.

Description

technical field [0001] The present application relates to the field of mechanical technology, in particular to an inner diameter detection device. Background technique [0002] An oil and gas transmission pipeline usually consists of multiple pipeline sections, and every two pipeline sections are connected by welding. After connecting multiple pipeline sections, it is necessary to use an inner diameter detection device to detect the inner diameter of the oil and gas transportation pipeline, so as to find out the geometrically deformed pipeline sections among the multiple pipeline sections in time, and then timely detect the geometrically deformed pipeline sections. segment to replace. [0003] In the related art, the inner diameter detection device may include a support tube, a support plate and a geometric probe located on the outer wall of the support tube, and the material of the support plate is rigid polycarbonate. The support plate is used to support the inner wall o...
