Abstract

The invention provides an integrally well forming type shaft tunneling machine which comprises overground equipment fixed on the ground and an in-shaft host machine tunneling underground, wherein theoverground equipment comprises a support structural frame and a propelling system; the support structural frame is fixed on the ground plane; the propelling system is mounted on the support structuralframe; the in-shaft host machine comprises a cutterhead, a masterdrive, a steel pipe ring and a support unit; a flange on the cutterhead is connected with the flange on the masterdrive through a high-strength bolt; the masterdrive provides torque for the cutterhead during the tunneling process; one end of the steel pipe ring is connected with the flange on the masterdrive; the other end of the steel pipe ring is connected with the support unit; and a piton rod in the propelling system directly faces the support unit area. The integrally well forming type shaft tunneling machine is high in degree of mechanization of overall structure, greatly lowers the labor intensity, adopts a steel pipe piece for supporting, is wide in geological adaptation, can be used for shaft tunneling in soft soil,pebble gravel, soft rock and hard rock stratums, integrates excavation, deslagging, and initial support, realizes seamless connection of all procedures and is high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of shaft construction, in particular to an integral well-forming shaft boring machine. Background technique [0002] With the increasing demand for underground engineering, the application range of shafts is becoming wider and wider. At present, the ordinary sinking method is used in many shaft constructions. This method has a slow excavation speed, a low degree of mechanization, a high risk to the safety of construction personnel, and high construction costs. Shaft boring machine is a kind of construction machinery for fast tunnel excavation, which can realize intelligent and unmanned underground construction. [0003] Invention patent CN108756888A "A Small-diameter Hard Rock Shaft Tunneling Machine" discloses a small-diameter hard rock shaft boring machine, which includes a shaft excavation host and a derrick installed on the ground, and the shaft excavation host is connected to the derrick through a lift...
