Square cross-section jacking-pipe tunneling machine

Abstract

The invention relates to a square cross-section jacking-pipe tunneling machine, which comprises a square shell of a square cross-section jacking pipe. The jacking pipe is divided into an operation cabin and a mud cabin by a cabin separating plate; a main motor and an auxiliary motor are arranged in the operation cabin; cutting mechanisms such as a main cutter disc, auxiliary cutters and a cutter are arranged in the mud cabin; the main motor is connected with the main cutter disc through a main shaft; the auxiliary motor is hinged to the left end of a connecting rod B through a crank throw and a connecting rod C; the left end of the connecting rod B is hinged with a support base A; the middle of the connecting rod B is hinged to a support rod which is fixed on the cabin separating plate; the left end of a connecting plate A is hinged to the cabin separating plate; the right end of the connecting plate A is hinged to a support base B; the support bases A and B are fixed on the auxiliary cutter body; two groups of auxiliary cutters and the drive mechanisms of the auxiliary cutters are respectively positioned on two sides of the mud cabin; and the cutter is arranged on the auxiliary cutters. With the adoption of the square cross-section jacking-pipe tunneling machine, a majority of soils are cut by the main cutter disc and the remained soils are cut by the auxiliary cutters, and a cutting surface is a regular square cross-section.

Description

1. Technical field [0001] The invention relates to a tunneling machine for pipe jacking, in particular to a tunneling machine for pipe jacking with a square section of a pipe jacking construction machine. 2. Background technology: [0002] At present, the roadheaders of square-section pipe jacking construction machinery use a plurality of circular drill bits to form an approximate square cutter head. When the cutter head cuts the square cutting surface of the square pipe jacking, there are many things that the cutter head cannot cut. In some places, the resistance during pipe jacking is particularly large, making construction difficult. 3. Contents of the invention: [0003] The present invention makes up for the shortcomings of the above pipe jacking equipment, and provides a square section pipe jacking machine capable of full section cutting. [0004] The present invention is achieved through the following technical solutions: [0005] A pipe jacking machine with a squ...
