Tunnel header main driving omnibearing direction adjusting device

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.
