Abstract

The invention discloses a cantilever type tunnel boring machine. A cable drum is connected with a machine tail of a machine body, and a wire inlet hole of an electric control box is opposite to the cable drum, so that the cable drum can move along with the machine body while winding a cable extending out of the wire inlet hole of the electric control box; an air cooling radiator is connected with the machine tail and is arranged close to a pump station, so that the air cooling radiator can cool the pump station, and the temperature of hydraulic oil in the pump station is prevented from being too high; meanwhile, the air cooling radiator can move along with the machine body; and the cable drum and the air cooling radiator are arranged at the machine tail, so that the overall weight of the tunnel boring machine can be increased, and the operation of the tunnel boring machine is more stable.

Description

technical field [0001] The invention belongs to the technical field of boring machines, and in particular relates to a cantilever type tunnel boring machine. Background technique [0002] Tunnel construction is mainly based on gun excavation and shield tunneling. Construction near existing lines and urban underground pipe corridors are not suitable for gun excavation construction. The one-time investment cost of using shield construction is too high, and it is not suitable to use shield construction in tunnels with variable diameter sections and tunnels with small turning radii. Therefore, the cantilever tunnel boring machine has obvious advantages in the excavation of medium and short-distance tunnels, the construction of variable diameter sections, and the disassembly and assembly of equipment. [0003] And the cantilever type tunnel boring machine in the prior art generally all needs to place cable reel and air-cooled radiator near the complete machine, and when the cant...
