Description
Technical field
The utility model is related to shield machine technical fields, and in particular to a kind of shield machine normal pressure tool changing knife lid, knife cylinder.
Background technology
With the continuous expansion of subway construction scale, shield-tunneling construction is answered extensively with its safe, fast, efficient feature
For in all kinds of underground engineering constructions such as city underground, municipal public use pipeline, oil transportation underground piping, coal mining.Shield is applied
Engineering method is the supportive section of jurisdiction that development machine builds tunnel while driving, and this Large-Scale Equipment of shield machine is used to carry out tunnel
Digging operation, shield machine can realize automated job, and construction personnel's labor intensity is low, and does not influence traffic above-ground and facility.
While shield machine tunneling, the cutter of shield machine can be constantly worn, if tool wear excessively and
It does not replace in time, then can destroy cutter head structure, cause shield-tunneling construction production that cannot be smoothed out, it is therefore desirable to periodically to shield
The cutter of machine is checked, is replaced.
The replacement of shield machine cutter is divided into tool changing scheme with pressure and normal pressure tool changing scheme, and tool changing scheme with pressure is needed to Tu Cang
Interior inflation takes other measures to reinforce stratum, to ensure soil stabilization in tunnel, prevents dregs, muddy water etc. from pouring into soil
Storehouse, tool changing scheme inspection with pressure, the enforcement difficulty for replacing cutter is big, the time is long, costly, many shield engineerings pass through it is important
Building and it is excessively extra large, when crossing river, the unfavorable geological conditions such as great burying, high hydraulic pressure bring the inspection and replacement of cutter very big
Risk and difficulty, part location does not have the condition of implementation even, if operating pressure is excessively high, no longer suitable for using tool changing with pressure
Technology.Normal pressure tool changing scheme can adapt to various bad working environments, and tool change time is short, exchanging knives process is safer, does not influence to apply
Work progress, therefore, normal pressure tool changing scheme are the developing direction that shield machine manufactures and designs.When designing shield machine, by by cutterhead
It carries out closed design and is capable of providing normal pressure tool changing environment, meet the requirement of normal pressure tool changing scheme, further, by by cutter
It is mounted on cutterhead in knife cylinder, then by knife cylinder, can realize the closed design of cutterhead, be changed for normal pressure can be carried out
For the shield machine of knife, knife cylinder is equivalent to the carrier of shield cutter, and cutter is pre-installed on knife cylinder, when normal pressure tool changing, passes through
More tool changing cylinder come achieve the purpose that replace cutter.
Currently, for existing knife cylinder, shield machine in normal tunneling process, muddy water and dregs can by cutter with
Gap between knife cylinder, which enters inside knife cylinder, to be made to be full of dregs inside entire knife cylinder, and is mounted with to monitor cutter in real time inside knife cylinder
The sensor and cable and knife cylinder hydraulic pressure abrasion detection pipe of rotation support the needs of pressure because of cutter head of shield machine, in entire knife cylinder
Portion is in high hydraulic pressure environment, and along with shield driving, dregs can constantly flow into knife cylinder collection slag, and then lead to the cable of sensor
Line is deformed or even is broken, and the extruding of hydraulic pressure abrasion detection pipe is made to touch cutter and pressure release occurs, and causes to make knife
The operation conditions of cutter cannot be accurately judged to by having real-time monitoring signals interruption and the alarm of hydraulic pressure abrasion detection, staff,
It can only finally stop tunneling, split out knife cylinder, delay construction.
