Pilot-tunneling roadway belt conveyor continuous gangue removing device for large-curvature-radius winding roadway construction

Abstract

The invention discloses a pilot-tunneling roadway belt conveyor continuous gangue removing device for large-curvature-radius winding roadway construction, and belongs to the field of coal mining equipment. The pilot-tunneling roadway belt conveyor continuous gangue removing device for large-curvature-radius winding roadway construction comprises a pilot-tunneling roadway, wherein a belt conveyor is arranged on an upper track and a lower track so as to be used for conveying raw coal and gangue; one end of a large-curvature roadway is connected onto the lower track; the other end of the large-curvature roadway is connected onto the upper track; the pilot-tunneling roadway is arranged on the outer side face of a curved face of the large-curvature roadway; one end of the pilot-tunneling roadway is connected onto the lower track; and the other end of the pilot-tunneling roadway is connected onto the upper track. According to the pilot-tunneling roadway belt conveyor continuous gangue removing device for large-curvature-radius winding roadway construction, the roadway design is optimized, the posterior gangue removing efficiency is improved, the equipment maintenance labor is reduced, and the pilot-tunneling roadway belt conveyor continuous gangue removing device for large-curvature-radius winding roadway construction can be widely applied to large-curvature-radius winding roadways such as a mine lot track car field and can solve the problem that the belt conveyor is off-tracking caused by the excessive belt turning radius of the belt conveyor, so that the belt conveyor can be continuously used.

Description

technical field [0001] The invention relates to the field of coal mining equipment, in particular, the invention relates to a continuous gangue discharge device of a belt conveyor for the construction of a curved roadway with a large curvature radius. Background technique [0002] The garages of the main tracks and alleys in underground coal mines are all curved roadways with large curvature radius. It is impossible to install long-distance belt conveyors for back road gangue removal. The transportation capacity and safety distance of simple belt installations are relatively small. The size requirements are relatively high, and continuous turning will easily cause the belt conveyor to deviate or increase the transfer point. The construction of a large-section curved roadway is not conducive to the later maintenance of the roadway and the needs of safe transportation. Under the background of continuous gangue removal by belt conveyors, the continuous gangue removal by belt co...

[0002] The garages of the main tracks and alleys in underground coal mines are all curved roadways with large curvature radius. It is impossible to install long-distance belt conveyors for back road gangue removal. The transportation capacity and safety distance of simple belt installations are relatively small. The size requirements are relatively high, and continuous turning is likely to cause the belt conveyor to deviate or increase the transfer point. The construction of a large-section curved roadway is not conducive to the later maintenance of the roadway and the needs of safe transportation.
