Abstract

The invention discloses a tunneling system which comprises a tunneling anchor machine, an anchor transporting all-in-one machine, a reversed loader, a self-moving machine tail and a rubber belt conveyor, the tunneling anchor machine comprises a rack, a cutting device and an anchor protection device, the anchor protection device comprises a lifting assembly, a working platform, a first drilling rig assembly and a stabilizing assembly, and the lifting assembly is arranged between the rack and the working platform; the first drilling rig assembly and the stabilizing assembly are arranged on the working platform, the working platform is telescopic, and the stabilizing assembly can be supported between the cutting device and a roadway top plate; the anchor transporting all-in-one machine is arranged behind the anchor digging machine, one end of the reversed loader is connected with the anchor transporting all-in-one machine, the reversed loader and the anchor transporting all-in-one machine can move synchronously, the reversed loader can be bent and arranged behind the anchor transporting all-in-one machine, the other end of the reversed loader is in lap joint with the self-moving machine tail, and the belt conveyor is arranged behind the self-moving machine tail. According to the tunneling system, the situation that a large empty roof distance exists at the head-on position is avoided, the risks of caving and large-amplitude bending and sinking at the tunneling head-on position are reduced, and safe production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of roadway excavation, in particular to an excavation system. Background technique [0002] The tunneling system is one of the six major systems in coal mines. The tunneling system is mainly used for tunneling and anchoring construction of underground roadways. The tunneling system includes roadheaders, transfer machines, belt conveyors and other equipment. The roadheaders cut the coal wall head-on, and the coal rocks produced by cutting need to be transported to the surface through subsequent transfer machines and belt conveyors to complete the tunneling. . In related technologies, the tunneling system has the risk of head-on falling and relatively large bending and sinking during the tunneling process, which is not conducive to the safe production of the mine. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain ex...
