Abstract

The invention discloses coal roadway rapid tunneling equipment and relates to the technical field of a coal mine roadway. The coal roadway rapid tunneling equipment comprises a collection box; the topend of the collection box is fixedly connected to an equipment platform; the top end of the equipment platform is fixedly connected to an equipment box; one end of the equipment box is fixedly connected to a fixing base; one end, away from the equipment box, of the fixing base is fixedly connected to a fixing column; one end, away from the fixing base, of the fixing column is rotatably connectedto a rotating base; the rotating base is fixedly connected to a driving rod; a telescopic end of the driving rod is rotatably connected to a main tunneling head; a crushing cutter head is arranged onthe main tunneling head; and the top end and the bottom end of the rotating base are fixedly connected to side fixing rods. Through the main tunneling head, the tunneling function can be realized; through a secondary tunnel head, the tunneling work can be assisted; through a collection device, coal briquettes generated in the tunneling process can be conveyed; and through a supporting device, thetop of the roadway generated by tunnel can be shoveled flatly and supported, and the safety of the tunneling work can be improved.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway construction, in particular to a coal roadway rapid driving equipment. Background technique [0002] The roadway excavation operation is the prerequisite for all other mining operations in coal mine production. With the substantial improvement of the working efficiency of the mining face, the contradiction that the roadway excavation speed cannot keep up with the mining demand has become more and more prominent in many mining areas. Safe, rapid and efficient roadway excavation and support technology is a necessary condition to ensure high production and high efficiency in coal mines. At present, there are three main methods for the mechanized rapid excavation of coal mine underground roadways: the first is the traditional single-lane excavation, and the main equipment on the working face is a roadheader and bolter; the second is double-lane excavation, which uses continuous coal mining m...
