An all-round direction adjustment device for the main drive of a tunnel boring machine

Abstract

A tunnel boring machine main drive all-round direction adjustment device applied in the field of tunnel boring machines, including a main drive housing, a propulsion cylinder, an upper left torque cylinder, an upper right torque cylinder, a bottom left torque cylinder, a bottom right Side torque oil cylinder, left upper end torque oil cylinder, left lower end torque oil cylinder, right upper end torque oil cylinder, right lower end torque oil cylinder, the main drive shell is installed inside the front shield shell, and the front end of the propulsion cylinder is fixed to the main drive shell. The tail part is fixedly connected with the tension shield, the upper left torque cylinder and the upper right torque cylinder are fixed on the upper part of the main drive shell, the bottom left torque cylinder and the bottom right torque cylinder are fixed on the lower part of the main drive shell, and the telescopic end Supported on the front shield shell. The invention has a novel structure and strong practicability, can reduce the risk of the boring machine jamming during the construction process of the tunnel boring machine, is convenient for direction adjustment, and can keep the boring machine driving upward at any time.

Description

technical field [0001] The invention relates to a tunnel boring machine main drive omnidirectional steering device in the field of tunnel boring machines. Background technique [0002] At present, when the tunnel boring machine is in the construction process, it is very important to be able to excavate smoothly in complex and changeable geology. Under weak and highly convergent surrounding rock conditions, there are greater risks of machine jamming and head-down excavation. The main drive of the roadheader has a certain direction adjustment function, 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 machine cannot complete the direction adjustment 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 diffic...
