Abstract

The invention relates to the technical field of roads, tunnels or mines, in particular to a rope saw tunneling device and tunneling method. The rope saw tunneling device includes a machine frame and tunneling components. The tunneling components each include a swing arm, a first pulley, a tunneling rod and a cutting rope. The swing arm can be disposed on the machine frame telescopically in a pivoted mode, the tunneling rod is fixedly disposed on the swing arm, the suspended end of the tunneling rod is provided with the first pulley, the plurality of tunneling components are disposed at intervals on the machine frame, the first pulleys in two adjacent tunneling components are matched with one cutting rope so that the two adjacent tunneling components and the cutting rope are matched to forma rope saw cutting component, which can adapt to constructions of tunnels of different diameters; and the application range is wide. The single cutting power needs are smaller, the control is easier,the efficiency is higher, and the cost is lower.

Description

technical field [0001] The invention relates to the technical field of roads, tunnels or mines, in particular to a wire saw tunneling device and a tunneling method. Background technique [0002] There have been some reports on the technology of cutting tunnels with wire saws. Disclosed a kind of pit tunnel boring machine as patent (CN105822316A). However, the disadvantages include: (1) only the periphery of the tunnel can be drilled, it is difficult to cut the center of the tunnel, it is difficult to adapt to tunnel sections of different sizes and shapes, and it is only suitable for small tunnels or tunnels. (2) One of its key technologies: when the roadheader is performing sawing work, the main motor 7 simultaneously drives the cutting wheels 6 in multiple sets of drilling and sawing mechanisms to rotate through the saw rope and multiple guide wheels 8, forming a wire saw cycle . The disadvantages are that the multi-set wire saws have long cutting lines and large frictio...
