Abstract

The invention discloses a tunnel borer using high-pressure water to break rock. Thetunnel borercomprises a shield shell, wherein the shield shell is fixedly connected with a side plate, and a cutter disc is arranged on one side of the side plate, and the cutter disc is provided with a plurality of through holes;a plurality of storage slots are formed in the side, away from the side plate, of the cutter disc, a cutter is disposed in each storage slot, and a shield cover is fixed on the other side of the side plate; and a first gear is disposed between the shieldcover and the side plate, and a rotating shaft is fixed to the center of the first gear, and one end of the rotating shaft penetrates through the side plate and is fixedly connected with the center of the cutter disc, and two first servo motors are symmetrically arranged on the side, away from the side plate, of the shield cover. The tunnel boreris simple in structure, the water pressure and water spray quantity can beconveniently adjusted, andnozzles operate separately, work efficiency isimproved, and resources aresaved.

Description

technical field [0001] The invention belongs to the technical field of tunneling machine equipment, and in particular relates to a tunnel boring machine which utilizes high-pressure water to break rocks. Background technique [0002] There are many types of roadheaders, which can be divided into ordinary machines and tunnel boring machines according to the operation objects. According to the operation methods, they can be divided into open type roadheaders and shield type roadheaders. ; As the traveling mechanism advances, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. [0003] However, the high-pressure water gun of the existing tunnel boring machine is inconvenient to operate, and each nozzle cannot be adjusted conveniently, and the water pressure cannot be adjusted conveniently. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the high-pressure water gun of ...
