Planing and transporting beam structure and machine group type coal mining unit

Abstract

The invention provides a planing and transporting beam structure and a machine group type coal mining unit, and relates to the technical field of coal mining machinery. The planing and transporting beam structure comprises a planing and transporting beam body; a plurality of coal mining units are arranged on the planing and transporting beam body; each coal mining unit comprises a first chain wheel, a second chain wheel and a chain used for connecting the first chain wheel and the second chain wheel; and a plurality of planing heads are arranged on the chain at intervals. The plurality of coal mining units are arranged on the planing and transporting beam body, so that the planing heads arranged on the chain of each coal mining unit rotate between the first chain wheel and the second chain wheel to realize coal mining operation; compared with the prior art, the plurality of coal mining units replace an original integral coal mining unit, an original chain is divided into a plurality of chains, the probability of chain breakage is reduced, and the safety of a working face is improved; and after the chain of a certain coal mining unit is broken, maintenance is convenient, other coal mining units do not need to be disassembled and assembled, meanwhile, the unit power can be properly improved, and the coal mining cutting capacity can be improved.

Description

Technical field [0001] The present invention relates to the field of coal mining machinery, in particular, involving a planing beam structure and a charter coal mining unit. Background technique [0002] The acute inclined coal seam refers to a coal seam of coal seam, and the mechanized mining of coal seam tilt angle is greater than 45 °, and the mechanization mining of medium and thick coal seams has always been a problem that plagues domestic and foreign mining. [0003] At present, the long-walled planing collection unit that has been exploited in China has been developed. The two ends of the entire unit's granted beam are set separately, and two sprockets are connected, and the planer is set by a chain. On the chain, coal is carried out through the rotation motion of the planer. Because the overall length of the planing beam is very large, the chain hazard of the single chain transfer power is high, and the chain is harmful to the working face. After the chain is broken, the ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a planing and transporting beam structure and a cluster-type coal mining unit, so as to alleviate the chain breaking risk of the existing planing and transporting fully mechanized mining unit due to the large overall length of the planing and transporting beam and the long-distance single chain transmission power The probability is high, the broken chain will cause harm to the personnel on the working face, it is inconvenient to maintain after the broken chain occurs, and the power of the unit does not exceed 200Kw, and the technical problem of limited coal cutting capacity
