Abstract

The invention relates to the technical field of a shield tunneling machine, and discloses a shield tunneling machine for tunnel driving. The shield tunneling machine for tunnel driving comprises a shield tunneling machine body, a cutter head is arranged on the left side of the shield tunneling machine body, and a hob is arranged in the middle of the cutter head; the outer side of the cutter head is fixedly connected with a connecting circular rail, a driving steel sleeve is movably connected to the other side of the connecting circular rail, and a driving inclined ring is fixedly connected tothe left end of the driving steel sleeve; and a jack hydraulic pump is fixedly connected to the right side of the cutter head. According to the shield tunneling machine for tunnel driving, a rotatingmachine, the driving steel sleeve and the connecting circular rail are arranged, the rotating machine drives the driving steel sleeve to open a way at the front end of the outer side of the cutter head while the cutter head is in driving state, the uneven pressure on the cutter head in the process of driving is effectively reduced, the stable and efficient rotation of the hob are ensured, disturbance to the cutter head surface is avoided, the accuracy of the driving direction is ensured, the degree of abrasion of the hob is reduced, the service life of the device is prolonged, and the accuracyand reliability of the device are improved.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a shield machine for tunnel excavation. Background technique [0002] Shield tunnel boring machine, referred to as shield machine, is a kind of special engineering machinery for tunnel boring. Modern shield tunnel boring machine integrates light, mechanics, electricity, hydraulics, sensing and information technology. It has the functions of excavating and cutting soil, Functions such as conveying soil muck, assembling tunnel lining, and surveying and guiding deviation correction involve multiple disciplines and technologies such as geology, civil engineering, machinery, mechanics, hydraulics, electricity, control, and surveying, and require "tailor-made" design and manufacture according to different geology , Reliability requirements are extremely high. At present, shield boring machines have been widely used in tunnel projects such as subways, railways, highways, municip...
