Long-distance large-burial-depth pipe jacking auxiliary installation device

The embodiment of the utility model discloses a long-distance large-burial-depth jacking pipe auxiliary installation device, a clamping device comprises a driving assembly used for rotating, and a first clamping assembly used for moving left and right to clamp and fix a jacking pipe is arranged on the front side of the driving assembly. A second clamping assembly used for being matched with the first clamping assembly to clamp and fix the jacking pipe is arranged on the rear side of the driving assembly. When the jacking pipe needs to be clamped and fixed, a rotary knob can be rotated to drive a transmission shaft to rotate, under the meshing connection effect of a second bevel gear and a first bevel gear, a gear is made to rotate, a first clamping plate and a second clamping plate are driven to move oppositely, the jacking pipe is clamped and fixed, and then lifting operation on the jacking pipe is achieved through a lifting device; therefore, the angle of the jacking pipe can be finely adjusted, and the jac
