Abstract

A supporting boot of a propelling device of a shield tunneling machine comprises a gland (1), a propelling seat (2), a connection plate (3), a top plate (4), a supporting plate (5), a supporting block(6), first bolts (7), a main propelling oil cylinder (8), a ball head (9), second bolts (10 and 11), a connection screw rod and nuts (13 and 14); the ball head (9) is a part of the main propelling oil cylinder (8) and is arranged at one end of the main propelling oil cylinder (8); the gland (1) is provided with an inner hole matched with the ball head (9), and the inner hole is provided with thespherical surface; the propelling seat (2) comprises a ball socket; the propelling seat (2) and the gland (1) are attached to the ball head (9); the ball socket of the propelling seat (2) makes spherical contact with the ball head (9); the gland (1) is fixedly connected with one end of the propelling seat (2) through the second bolts (10 and 11); one end of the connection plate (3) is fixedly connected with the other end of the propelling seat (2) through the connection screw rod and the nuts (13 and 14), and the other end of the connection plate (3) is connected with the supporting plate (5)through the first bolts (7); and the top plate (4) is fixedly connected with the connection plate (3). The supporting boot can conduct automatic adjusting steering so as to be closely attached to a pipe segment.

Description

technical field [0001] The present application relates to a shoe for a propulsion device of a shield machine. Background technique [0002] The shield machine excavates the tunnel and moves forward continuously. The support shoe is in direct contact with the surface of the segment. Ideally, it is completely fitted, and the overall stress effect on the shield body is the most ideal. The support shoe is an important force transmission device of the propulsion device of the shield machine, which requires the ability of automatic adjustment and adaptation, which has higher requirements for its fixing method, so the use of spherical contact and spring compression is an important measure. The existing main thrust cylinders often bear additional loads during actual use, which will generate bending moments, making the cylinders unable to work at their best. Contents of the invention [0003] The purpose of this application is to solve the problem that the main push cylinder does ...
