AI Technical Summary

Problems solved by technology

The reaming bit uses an insert hob to break rock, and the hob usually loses its ability to break rock due to hob seal failure, bearing failure, shell or cutter shaft damage, and tool holder breakage;
[0010] (2) The drill pipe breaks
The fracture position of the drill pipe is mostly in the stress concentration area at the root of the threaded thread. Fatigue damage occurs after the threaded thread of the drill pipe is worn. When the torque and tension exceed the bearing capacity, the drill pipe is prone to breakage
[0011] During the construction process of the raising drilling rig, the drill pipe and the reaming bit are all underground, and it is impossible to observe and detect them intuitively; the operation status and maintenance of the drilling rig mainly rely on the experience of the construction personnel, and rely on the traditional listening, touching, and seeing. Analyzing and judging by means, the reliability is poor, and misjudgment is prone to occur, especially in the stage of reaming construction, which may easily lead to accidents

Abstract

The embodiment of the invention provides a raise boring machine cutterhead and drill rod vibration monitoring method, system and device and a computer readable storage medium. The method comprises thesteps that drill rod vibration signals are collected; the collected drill rod vibration signals are preprocessed; signal characteristics of the preprocessed drill rod vibration signals are extracted;and the signal characteristics are put into a pre-trained neural network model to obtain an output corresponding classification result. According to the method, in this way, manual experience judgment is not needed, the influence of background noise in an actual engineering environment is eliminated, the distinction degree of vibration signals of the raise boring machine under different working conditions is enhanced through extraction of various characteristics, the fault diagnosis accuracy and feasibility are improved, the working safety of the raise boring machine is guaranteed, the shutdown inspection frequency is reduced, and the working efficiency is improved.

Description

technical field [0001] Embodiments of the present disclosure relate generally to the field of raiseboring rig fault detection, and more particularly, to a method, system, apparatus, and computer-readable storage medium for monitoring vibration of a raiseboring rig cutterhead and drill pipe. Background technique [0002] The raise drilling rig drives the hydraulic motor through the motor of the drilling rig, the hydraulic motor drives the faucet, and uses the hydraulic power to transmit the torque to the drilling tool system, driving the drill pipe and the drill bit to rotate, and the hob on the pilot hole drill bit or the reaming bit is under drilling pressure. Under the action of the rock working face at the bottom of the well, it will do pure rolling or slight sliding. At the same time, the axial tension and pressure generated by the oil cylinder of the main engine also act on the pilot hole drill bit or the reaming drill bit through the power head and drill rod, so that t...
