Abstract

The invention discloses a stabilizer. The stabilizer comprises a support shell, an abutting shoe and a telescopic driving portion. The first end of the support shell is fixedly connected with a steelpipe ring. The abutting shoe is nested with an opening in the second end of the support shell. The telescopic driving portion is arranged between the support shell and the abutting shoe. When the telescopic driving portion is activated, the telescopic driving portion drives the abutting shoe to press against the well wall relative to the support shell till the abutting shoe abuts against the wellwall, so that the steel pipe ring is fixed relative to the well wall, the fixing of the steel pipe ring is achieved, the risk that rotation is generated due to reverse torque of the steel pipe ring isreduced, the risk of vibration of the shaft boring machine is further lowered, and the safety is naturally improved. Therefore, the stabilizer has the beneficial effects of improving the safety of the shaft boring machine. The invention further discloses the shaft boring machine including the 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...
