Full-face rectangular hard rock tunneling and anchoring integrated machine

Abstract

The invention relates to a machine for tunneling a coal mine roadway, in particular to a full-face rectangular hard rock tunneling and anchoring integrated machine. The full-face rectangular hard rock tunneling and anchoring integrated machine comprises a machine frame which is sequentially provided with a cutting device, a support device, a propelling mechanism, a side supporting mechanism, a rear supporting mechanism and a ventilation dust removal device from front to back; a deslagging mechanism is arranged in the middle of the machine frame in the horizontal direction; the front end of the propelling mechanism is fixed on the machine frame, and the rear end of the propelling mechanism is fixed on the side supporting mechanism; the cutting device consists of a cutterhead, a cutterhead supporting frame and a cutterhead driving mechanism; the cutterhead supporting frame is fixedly connected with the front end of the machine frame; the cutterhead comprises a combined cutterhead frame consisting of a conical top and a cylindrical bottom; a plurality of disc cutters are arranged at the peripheries of the conical top and the cylindrical bottom of the cutterhead frame; and the cone angle alpha of the conical top of the cutterhead is 140 to 160 degrees. By the full-face rectangular hard rock tunneling and anchoring integrated machine, the problems that the conventional tunneling machine is not suitable for full-face hard rock quick tunneling work, cutting teeth are high in wear speed when cutting hard rock, a machine body vibrates greatly, and reliability is low can be solved, the tunneling working efficiency of the full-face rectangular roadways can be improved greatly, labor intensity of workers can be reduced, and working environment and equipment reliability can be improved.

Description

technical field

[0001] The invention relates to coal mine roadway excavation machinery, in particular to a full-section rectangular hard rock bolting integrated machine, especially suitable for excavating semi-coal rocks, coal rocks and hard rock roadways whose end faces are rectangular in shape of 4<f<10, or f Tunneling operations in hard rock rectangular roadways >10. Background technique

[0002] Since the early 1990s, with the development of the national economy and the integration of national coal resources, there have been more and more mine roadways. The geological conditions of the roadways are complex and changeable, and the rock hardness has increased. Light-duty and medium-duty roadheaders can no longer meet the needs, so a new type of roadheader is needed.

[0003] In the past few years, the number and types of roadway boring machines in my country have been increasing, but they all belong to semi-coal and rock partial-section roadheaders and cantilever...
