Auxiliary balance propelling device for shield construction

Abstract

The invention discloses an auxiliary balance propelling device for shield construction, and relates to the technical field of shield construction. A steering wheel angle monitoring assembly is arranged between a steering wheel and an installation driving device. The steering wheel angle monitoring assembly can detect the steering angle of the steering wheel to facilitate control on the steering tunneling angle of the steering wheel. According to the invention, the angle detection is accurate and reliable, the rotation angle of the steering wheel can be adjusted in space, the shield tunneling direction can be controlled conveniently, the tunneling precision is guaranteed, and meanwhile the balance in the tunneling process can be guaranteed in horizontal linear tunneling. The balance counterweight assembly can balance the unbalanced force on the installation driving device caused by the inclination angle of the steering wheel, the auxiliary balance propelling device is simple and convenient, can guarantee the balance of rapid tunneling, and prevent the problem that the shield is damaged or an accident occurs due to the fact that the unbalanced force is too large in the shield construction tunneling process.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to an auxiliary balanced propulsion device for shield tunneling. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of shield tunneling is the "shield" (referring to the supporting segment) of the tunnel constructed (laid) by the roadheader while excavating, which is different from the open construction method. Internationally, the generalized shield machine can also be used in rock formations, but it is different from the open (non-shield method) tunnel boring machine. In our country, it is customary to call the tunnel boring machine used in soft ground as (narrowly defined) shield machine. [0003] At present, most of the shield machines on the market use the hydraulic drive column to realize steering and propulsion. When in use, due to the low underground temperature, the hydraulic pipe is easy...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the shield machines on the market use the hydraulic drive column to realize steering and propulsion. When in use, due to the low underground temperature, the hydraulic pipe is easy to solidify during transportation, which leads to failure of the hydraulic drive column. At the same time, due to thermal expansion and contraction, in low temperature environment, it will lead to insufficient oil supply, which will lead to direction deviation

Moreover, it is difficult to accurately control the direction of excavation, and in the process of non-linear excavation, the unbalanced force at the front end of the excavation often causes deflection at the rear of the shield machine, which in turn aggravates the error of the excavation direction and reduces the service life
