Embodiment Construction

[0038] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the examples. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0039] The embodiment of the present invention discloses an automatic deployment device for microseismic sensors mounted on a TBM to solve the technical problem in the prior art that the advancement of sensor arrays requires manual disassembly and assembly of sensors, which seriously affects personnel safety and full-time monitoring.

[0040] like Figure 1-Figure 7 As shown, the automatic deployment device 3 of the embodiment of the present invention is installed on the H-shaped steel rail 4, and its anti-skid pad 13 is close to the rock wall 1. The H-shaped steel rail is welded o...

Abstract

The invention discloses an automatic deployment device for a TBM equipped with a microseismic sensor, which includes a sliding-reset mechanism, a rock wall coupling mechanism, a drilling mechanism and a clamping mechanism. The drilling mechanism includes a drilling motor 24, a drilling motor gearbox, a drilling The threaded rod, the tapping drill bit and the main body of the microseismic sensor can realize automatic microseismic monitoring, improve the mechanization and automation of TBM construction operations; can keep relatively static with the hole wall during the TBM excavation process, and automatically reset when the displacement reaches the maximum ; It can realize the automatic tightening of the microseismic sensor body when it is installed, and the automatic loosening of the microseismic sensor body when it is working, so as to ensure the smooth installation of the microseismic sensor body and block the conduction of TBM vibration.

Description

technical field [0001] The invention relates to the field of microseismic monitoring, and more particularly relates to an automatic deployment device for microseismic sensors mounted on a TBM. [0002] technical background [0003] Full-face tunnel boring machine (Tunnel Boring Machine, TBM) is a highly integrated and mechanized rock tunneling equipment. TBM can realize a series of processes such as cutter head cutting face rock, belt conveying crushed stone, rock bolt anchoring rock mass, steel arch installer assembling steel arch support, shotcrete bridge shotcrete, etc., to ensure the rapid and safe operation of rock tunnels , high-quality construction, is an important tunnel construction method widely used at home and abroad. [0004] With the development of economy and society, TBM construction more and more frequently encounters engineering environments with poor rock quality, high buried depth, and high ground stress. Under such occurrence conditions, the stress redi...
