Stabilizer and shaft boring machine

Abstract

The invention discloses a stabilizer, which comprises a supporting shell, an abutting shoe and a telescopic driving part. The first end of the supporting shell is fixedly connected with the steel pipe ring; the abutting shoe is nested with the opening provided at the second end of the supporting shell; the telescopic driving part is arranged between the supporting shell and the abutting shoe. When the telescopic driving part is activated, the telescopic driving part will drive the abutment shoe against the support shell to press against the well wall until the abutment shoe is against the well wall, so that the steel pipe ring is fixed relative to the well wall, realizing the fixation of the steel pipe ring and reducing the steel pipe ring The risk of reverse torque rotation will be reduced, thereby reducing the risk of vibration of the shaft boring machine, and the safety will naturally be improved. Therefore, the stabilizer provided by the present invention is beneficial to improving the safety of the shaft boring machine. The invention also discloses a shaft boring machine including a stabilizer.

Description

technical field [0001] The invention relates to the field of excavation equipment, in particular to a stabilizer. The invention also relates to a shaft boring machine comprising a stabilizer. Background technique [0002] With the acceleration of the urbanization process and the increasing demand for various urban lands, the development speed of urban rail transit and comprehensive pipe corridors has also accelerated. Shafts for infrastructure such as optical fibers are mostly obtained by vertical tunneling with shaft boring machines. Existing shaft boring machines usually include a cutter head, a main drive and a steel pipe ring. During the excavation process, the reverse thrust and reverse torque of the rock-soil medium on the cutter head are transmitted to the steel pipe ring through the main drive. However, the steel pipe ring is very easy to rotate under the action of the reverse torque, which will cause the vibration of the shaft boring machine, thereby destroying th...
