In-service drill rod detection device and method

Abstract

The invention provides an in-service drill rod detection device which comprises a magnetic flux leakage detection module and a frame. The frame is circumferential, and the magnetic flux leakage detection module is installed on the frame. The in-service drill rod detection device is characterized in that the in-service drill rod detection device further comprises a cleaning and purging module, an outer diameter measurement module and a marking module; the cleaning and purging module, the outer diameter measurement module and the marking module are all installed on the frame; a crawler executingmechanism on the cleaning and purging module can drive the whole device to advance; the cleaning and purging module cleans the surface of the drill rod in the advancing process; the magnetic flux leakage detection module detects magnetic flux leakage, and the outer diameter measurement module measures the outer diameter; and abnormal parts are marked through the marking module. The device can automatically and simultaneously clean and derust the surface of the drill rod, detect magnetic flux leakage, measure the pipe diameter, mark and the like, and solves the problems of tedious manual operation steps, low precision, time waste and labor waste.

Description

technical field [0001] The invention relates to an in-service drill pipe detection device and a detection method. Background technique [0002] In-service drill pipes need to be inspected after being used for a period of time. The inspection items include magnetic flux leakage inspection, pipe outer diameter measurement, etc. Through inspection, unqualified drill pipes can be found in time to avoid drill pipe breakage and leakage accidents during drilling operations and reduce property. Losses, to ensure operational safety. [0003] In the actual detection process, for the magnetic flux leakage detection project, the magnetic flux leakage detection trolley walks on the suspended drill pipe. The magnetic flux leakage detection trolley is equipped with an excitation coil and a magnetic flux leakage signal probe. The excitation coil applies a longitudinal magnetic field to the drill pipe. The magnetic flux leakage signal probe detects the magnetic flux leakage signal on the su...
