Pipe detecting system

Abstract

The invention provides a pipe detecting system which comprises a signal acquisition device and a signal processing device, wherein the signal acquisition device comprises a transmission structure and an acquisition structure which are fixedly connected with each other through a fixing bracket; the acquisition structure comprises a sealed cabin and a rotary transformer fixedly mounted in the sealed cabin; the rotor shaft of the rotary transformer penetrates out of the side wall of the sealed cabin; the transmission structure comprises a transmission main shaft and a transmission auxiliary shaft which are mounted on one support frame in parallel; the distance between the transmission main shaft and the transmission auxiliary shaft can be adjusted through a fine adjustment component arranged on the support frame; one end of the transmission main shaft is connected with the rotor shaft of the rotary transformer through a flexible coupler; the output end of the rotary transformer is connected with the signal processing device; one end of the fixing bracket is fixedly connected with the sealed cabin; the other end of the fixing bracket is fixedly connected with the support frame. The pipe detecting system can be used in harsh environments, and can obtain accurate and reliable pipe axial position information.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing and automatic flaw detection, in particular to a pipe material testing system. Background technique [0002] In the process of inspecting the pipe, it is necessary to locate the acquired detection signal in the axial direction. Once a defect is found on the pipe, the position of the defect in the axial direction of the pipe should be quickly determined. [0003] In the prior art, the positioning of the axial position of the pipe is obtained by transmitting the collected axial position signal to the interface of the detector through an optical encoder, and then processing and analyzing it through the detector. However, optical encoders have poor radiation resistance, are easily damaged, have short service life, and are unsatisfactory in stability and reliability in underwater high-radioactive environments. [0004] Moreover, the signal transmitted from the optical encoder to the de...
