Drilling rod magnetic memory online detection system

Abstract

The invention discloses a drill rod magnetic memory online detection system which comprises: a mounting bracket and a drill rod, wherein a flaw detection platform is arranged on one side of the mounting bracket; a stress concentration magnetic detector which is arranged above the flaw detection platform; bull eye wheel bolts, whereinfour bull eye wheel bolts are arranged on the outer portion of the stress concentration magnetic detector body, the bull eye wheel bolts are sequentially arranged on the outer portion of the stress concentration magnetic detector body, and the bull eye wheel bolts and the stress concentration magnetic detector body are connected into an integrated structure. and eight roller swing mechanism bodies which are arranged on the stress concentration magnetic detector, wherein magnetic memory on-line detection probes are arranged on the eight roller swing mechanism bodies. In the drill lifting process of a drilling machine, flaw detection operation is carried out on drill rods at the same time, and the original tedious process that the drill rods need to be transported to a detection manufacturer from a construction site and then detected one by one is omitted.

Description

Technical field [0001] The present invention relates to the field of drill rods, and more particularly to a diamond magnetic memory online detection system. Background technique [0002] Although the drill rod has been fully tested before the factory, because the drilling construction conditions are complex, the environment is more harsh, the drill pipe is used after use or when used to a certain extent, and its performance will necessarily decrease, and It is possible to generate stress concentration, defective zone, etc. In order to avoid these damage to subsequent drilling construction, a detailed requirement for the service life and use performance of the drill pipe in the relevant procedures of drilling construction. In order to grasp if its various performance indicators are qualified, under certain conditions, there is no damage to the drill pipe after use. [0003] At present, the entire detection process is more complicated. First, the construction team should be used, r...

AI Technical Summary

Problems solved by technology

[0003] At present, the entire inspection process is relatively complicated. First, the construction team has to load the drill pipes ready for inspection after use, and then transport them to manufacturers with inspection qualifications and inspection capabilities. The manufacturers then follow relevant regulations and standards in a certain space The drill pipe inspection tool and conventional detector are used to inspect the drill pipes one by one, and then transported to the construction unit after completion

This will not only consume a lot of manpower, material resources and financial resources, but also affect the work efficiency of the construction team.
