Problems solved by technology

[0003] However, due to the different geology in the process of excavation, the above-mentioned technical solutions require operators to have rich experience and be able to cope with various situations of geology and equipment. Therefore, long-term training is required, which increases the consumption of manpower and material resources, and the original The operation of the equipment is relatively high, requiring the operator to concentrate for a long time, increasing the labor intensity of the operator, and the efficiency of the excavation will also be reduced. Therefore, we have improved this and proposed a TBM automatic excavation. method

Embodiment

[0036] Such as figure 1 As shown, the embodiment of the present invention provides a method for realizing automatic tunneling of TBM, specifically according to the following operation steps;

[0037] S1: Automatic step change, during the step change process, the way of step change will affect the cutting tool and the speed of excavation;

[0038] S2: automatic excavation, excavating the excavation tunnel;

[0039] S3: Automatic shutdown, providing emergency stop for unexpected accidents, and providing normal stop when workers need to rest;

[0040] S101: confirm the position, confirm the falling position of the support; confirm the next position of the brace; confirm the return position of the bolter and confirm the next position;

[0041] S102: Change steps, tighten the shield cylinder, stretch out the back support and tighten it, retract the shoe cylinder and put it in place, retract the pusher cylinder, put the shoe mechanism in place, extend the shoe and tighten it, retr...

Abstract

The invention provides a method for realizing automatic tunneling of a TBM (Tunnel Boring Machine), and relates to the technical field of automatic tunneling of the TBM. S1; the method comprises the following steps: S101, automatically changing steps; the position is confirmed, S102; step changing action is carried out, and S103; s2, performing alarm prompt; the method comprises the following steps: S201, automatically tunneling; in an empty pushing mode, S202; in a tunneling mode, S203; s3, a direction adjusting mode; the method comprises the following steps: S301, automatically stopping; emergency shutdown is carried out, and S302; according to the TBM tunnel boring machine, automatic operation, fault action and parameter selection are achieved during use, the equipment performance is played to the maximum extent, an operator mainly conducts equipment monitoring, the ability requirement of the operator and the working intensity are lowered, and the tunneling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of TBM automatic excavation, in particular to a method for realizing automatic TBM excavation. Background technique [0002] With the development of cities, tunnels in my country, especially large-diameter TBM tunnels, have developed rapidly in recent years, such as a composite micro-TBM construction method and micro-TBM with application number CN202011392103.9. The method includes the following steps: Excavation The starting hole; the miniature TBM will be assembled; the cutter head will be excavated, the cylinder will be pushed to push the TBM head; , repeat the steps for TBM method construction. Wherein, the miniature TBM includes a TBM head and a trolley mechanism, a propulsion support mechanism is arranged between the TBM head and the trolley mechanism, and the front end of the propulsion support mechanism pushes against the rear end of the TBM head. Adopting this invention can realize TBM excavation of...
