Abstract

The invention relates to a coal mine shaft inspection device and a laser scanning defect detection method, and the device comprises: an inspection device body which is arranged in a shaft and moves up and down in the shaft; an external driving device which is used for driving the inspection device body to move up and down; a guide steel wire rope which is vertically erected between the two corresponding tensioning devices; body guide devices which are uniformly distributed and fixed on the side wall of the inspection device body in the circumferential direction, wherein the guide steel wire ropes penetrate through the body guide devices in a sliding manner; a positioning system which comprises a plurality of UWB nodes arranged on the inner wall of the shaft and a UWB node arranged on the inspection device body. An energy supply battery pack, a wireless communication module, a laser radar and the image acquisition platform which are mounted on the inspection device body; the energy supply battery pack is used for supplying power to the wireless communication module, the laser radar and the image acquisition platform; and the wireless communication module has a wireless communication function and a UWB node-based positioning function. According to the invention, the current situation that the existing manual inspection efficiency is low and potential safety hazards exist can be effectively changed.

Description

technical field [0001] The invention belongs to the technical field of mine safety, and in particular relates to a coal mine shaft inspection device and a laser scanning defect detection method. Background technique [0002] In the process of coal mining, the shaft is one of the most important parts. The shaft undertakes a number of different tasks, including picking up and sending underground workers, driving and mining equipment and materials up and down the shaft, and transportation of raw coal, etc. . Potential problems such as cracking, deformation, and local concrete spalling on the inner wall of the shaft that have been working under complex ground stress conditions for a long time are in urgent need of effective detection methods. At present, most of the inspections on shaft shafts are done manually, specifically by arranging special personnel to conduct inspections. This manual inspection method is inefficient, prone to missing inspections, and has various safety ...
