Soil bin monitoring device for shield machine

Abstract

The invention discloses a soil bin monitoring device for a shield machine. The soil bin monitoring device comprises a soil bin monitoring body, a mounting base and a gate structure. The mounting baseis a fixing part of the soil bin monitoring body, is of a hollow cylindrical structure and is provided with a first telescopic mechanism. The soil bin monitoring body is mounted in the hollow cylindrical structure of the mounting seat in a front-back moving manner through the first telescopic mechanism. The gate structure is fixedly mounted between the outer side of a soil bin wall plate and the mounting seat, and is provided with a second telescopic mechanism and a gate. When the soil bin monitoring body retracts for maintenance or replacement, the gate structure is closed so as to prevent muck in the soil bin from rushing out through the soil bin monitoring body mounting seat and a mounting hole under the action of pressure. In order to ensure that the soil bin monitoring body can conveniently extend into the soil bin, the gate structure is of a push-pull structure. A through hole is formed in the position, corresponding to a drift diameter of the gate structure, of the soil bin wallboard.

Description

technical field [0001] The invention relates to a monitoring device for an earth bin of a shield machine, in particular to a telescopic earth bin monitoring device for a shield machine. Background technique [0002] At present, in the prior art of the shield machine, the soil bin monitoring device is usually directly fixed and installed in the soil bin, which is used to monitor or observe the flow of muck in the soil bin, the excavation surface and the wear of the tool during the excavation construction of the equipment. However, in the actual excavation construction of the shield machine, due to the splash of muck in the earth bin, the monitoring device of the earth bin is often damaged or the surface is attached by muck, which makes the monitoring device unable to effectively and normally collect relevant image information. In order to restore the effectiveness of the soil bin monitoring device, this prior art generally uses high-pressure water flow or air jet spraying on ...

Problems solved by technology

This treatment method often leads to the phenomenon that the slag will condense at the water and air nozzles, and then block the pipeline, and even cause the pipeline equipment to accumulate too much pressure and rupture

In view of the damage defect of the soil bin monitoring device, it is necessary for the operator to enter the soil bin to replace it.

Therefore, the existing technology of directly fixing and installing the soil bin monitoring device in the soil bin has high maintenance and repair costs in use, and is very inconvenient, which is not conducive to the improvement of the economic benefits of the enterprise.
