Problems solved by technology

[0002] At present, square-top pipe construction machinery uses four circular cutterheads to form an approximate square cutterhead. The section excavated by this cutterhead has many places that cannot be excavated by a circular cutterhead, and the resistance during pipe jacking is particularly high. large, difficult to construct

Abstract

A square jacking pipe comprises an outside shell and a bin plate which partitions a slurry bin and an equipment bin. A gearbox is mounted in the middle of the jacking pipe, a transmission shaft is arranged at the left end of the gear box, and a circular cutter disc is arranged at the left end of the transmission shaft. A plurality of cutters are arranged on the circular cutter disc, and a square cutter disc is arranged between the circular cutter disc and the gearbox. The middle of the square cutter disc is fixed at the left end of a big arm, a bearing is hinged to the right end of the big arm, and the bearing is fixed on the gearbox. A base is fixedly connected to the upper portion of the square cutter disc, and the left end of a drive arm is hinged to the base. An eccentric bearing is mounted at the right end of the drive arm, a shaft hole of the eccentric bearing is formed in a rotating shaft, and the rotating shaft is driven by the gearbox.

Description

technical field [0001] The invention relates to a pipe jacking, in particular to a square pipe jacking construction machine for pipe jacking. Background technique [0002] At present, square-top pipe construction machines use four circular cutterheads to form an approximate square cutterhead. The section excavated by this cutterhead has many places that cannot be excavated by circular cutterheads. The resistance is particularly high when jacking pipes. Big and difficult to construct. Contents of the invention [0003] The invention makes up for the above shortcomings of pipe jacking, and provides a square pipe jacking capable of full-section excavation. [0004] The present invention is achieved through the following technical solutions: [0005] A square jacking pipe, including an external shell, a bin plate separating the mud tank and the equipment bin, a gearbox installed in the middle of the jacking pipe, a transmission shaft at the left end of the gearbox, and a cir...
