Problems solved by technology

However, when faced with hard rock with good integrity and high strength, the rock mass cannot be cut quickly only by the mechanical effects of wedge, cutting, and pressure of the cutter head, and the rock mass is often ground into rock powder. Engineering Phenomena Caused by Reduced Driving Speed ​​of Roadheader

Abstract

The invention discloses a tunneling device with the drilling distance being adjustable and a tunneling machine. The tunneling device comprises a cutterhead, multiple heads, a fixing mechanism and drilling mechanisms, and the heads are vertically arranged on the cutterhead and slidably connected with the cutterhead. The fixing mechanism is used for fixing the heads sliding on the cutterhead onto the cutterhead so as to adjust the positions of the heads on the cutterhead. The drilling mechanisms are arranged on the cutterhead and comprise drill rods capable of stretching out and drawing back inthe axial direction on the cutterhead. The drilling mechanisms are arranged on the cutterhead, drilling pre-breaking to to-be-excavated rock mass is completed through the drilling mechanisms, then theheads are arranged on the cutterhead and slidably connected with the cutterhead, the positions of the heads on the cutterhead are adjusted, finally the to-be-excavated rock mass is tunneled through the cutterhead with the positions of the heads adjusted, the mechanical property of the heads can be better exerted, and therefore the aim of efficiently tunneling the to-be-excavated rock mass is achieved.

Description

technical field [0001] The invention belongs to the technical field of roadheaders, and in particular relates to a roadheader and a roadheader with adjustable drilling distances. Background technique [0002] The tunneling efficiency of tunnel boring machine (TBM) depends on the electromechanical and hydraulic performance of the tunnel boring machine itself, and also depends on the physical and mechanical properties of the rock mass to be excavated. In the case of complete hard rock excavation (cracks are not developed, rock mass integrity is high, and the uniaxial compressive strength of rock is greater than 150MPa), the roadheader in the prior art has poor adaptability and cannot fully exert the mechanical performance of the roadheader, resulting in engineering The excavation efficiency is low, which delays the progress and cycle of the project. [0003] And the existing tunneling device that is used for tunneling of roadheader is generally fixedly arranged at the positio...
