Problems solved by technology

The tunnel boring machine currently used in the field of tunnel boring machine cannot complete the steering function of the main drive through the existing equipment, and can only adjust the orientation of the main drive manually. The workload is large, the adjustment range is limited, and the adjustment is difficult Obviously solve the problems of machine jamming and keeping the head of the roadheader up and digging, so that there is a huge risk in the construction of the roadheader

Abstract

A tunnel header main driving omnibearing direction adjusting device used in the field of tunnel headers comprises a main driving shell body, a pushing oil cylinder, an upper left side torque oil cylinder, an upper right side torque oil cylinder, a bottom left side torque oil cylinder, a bottom right side torque oil cylinder, a left side upper end torque oil cylinder, a left side lower end torque oil cylinder, a right side upper end torque oil cylinder and a right side lower end torque oil cylinder. The main driving shell body is arranged in a front shield shell body. The front end of the pushing oil cylinder and the main driving shell body are fixed. The tail is fixedly connected with a supporting shield. The upper left side torque oil cylinder and the upper right side torque oil cylinder are fixed on the upper portion of the main driving shell body. The bottom left side torque oil cylinder and the bottom right side torque oil cylinder are fixed on the lower portion of the main driving shell body. A telescopic end is supported on the front shield shell body. The device is novel in structure and high in practicability, during a tunnel header construction process, header blocking risks can be lowered, direction adjusting is convenient, and the fact that a header carries out upward heading at any time can be kept at any time.

Description

Technical field [0001] The invention relates to an omnidirectional direction adjustment device for a main drive of a tunnel boring machine in the field of tunnel boring machine. Background technique [0002] At present, when the tunnel boring machine is in the construction process, it is very important to be able to tunnel smoothly in the complex and changeable geology. Under the surrounding rock conditions such as weak and high convergence, there are greater risks of jamming and low head tunneling. The main drive of the tunnel boring machine has a certain function of direction adjustment, which has always been a new issue to be solved in the construction process of the tunnel boring machine. The tunnel boring machine currently used in the field of tunnel boring machines cannot complete the main drive direction adjustment function through the existing equipment. It can only adjust the main drive position manually. The workload is large, the adjustment range is limited, and the ad...
