Vertical shaft shield tunneling machine and cutterhead system thereof

Abstract

The invention discloses a vertical shaft shield tunneling machine and a cutterhead system thereof, and belongs to the technical field of vertical shaft construction. The vertical shaft shield tunneling machine comprises a working platform, an operation room is fixedly mounted at the top of the working platform, a platform plate is fixedly connected to the top of the operation room, and an equipment mounting room is fixedly mounted at the top of the platform plate; a main beam is fixedly connected to the bottom of the working platform, an expanding and pushing mechanism is fixedly mounted at the upper end of the outer side of the main beam, a segment erector is fixedly mounted at the middle end of the outer side of the main beam, and a driving device is fixedly mounted at the lower end of the outer side of the main beam; and a mounting seat is fixedly connected to the bottom of the driving device, a cutter mechanism is fixedly mounted in the mounting seat, a muck discharging mechanism is fixedly mounted in the center of the interior of the cutter mechanism, and a slurry mechanism is fixedly mounted on the right side of the mounting seat. The expanding and pushing mechanism is arranged and used for supporting the well wall and adjusting the running direction of the equipment.

Description

technical field [0001] The invention relates to the technical field of shaft construction, and more specifically, relates to a shaft shield machine and a cutterhead system thereof. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield tunneling machine is the "shield" of the tunnel built by the roadheader while digging, which is different from the open construction method. Internationally, the generalized shield machine can also be used in rock formations, but it is different from the open tunnel boring machine. In my country, tunnel boring machines used in soft ground are customarily called shield machines. According to the working principle, shield machines are generally divided into manual shield tunneling, extrusion shield tunneling, semi-mechanical tunnel tunneling, and mechanical tunnel tunneling.

Problems solved by technology

Whether it is the ordinary sinking method or the current mechanized excavation, workers need to go down the well and operate in a small space in the formation. This method has a slow excavation speed, low degree of mechanization, great safety risks for construction personnel, and high construction costs. Moreover, the slag removal method commonly used by shaft shield machines on the market today is mainly the downward slag removal method, but the downward slag removal method needs to excavate a slag transport channel at the bottom of the cave to transport the discharged slag, so that other The use conditions are very limited; it is not suitable for rock formation geology, which brings harsh requirements to the construction and is not conducive to use
