Description

Continuous-mining and continuous-transporting cooperative conveying system

Technical Field

The utility model relates to a colliery is tunnelling in the pit and is transported technical field, especially relates to a continuous production and continuous transportation are conveying system in coordination.

Background

Along with the rapid development of automation and intellectualization of coal mines, the flexible and movable reversed loader and the carrying conveyor are more and more widely applied to a matched conveying system after tunneling, the moving distance and flexibility of the reversed loader, the moving flexibility of the tail of the carrying conveyor and the length of a storage belt directly influence the tunneling distance and efficiency of the mining all-in-one machine, and further the production capacity and efficiency of a coal face are determined to a great extent.

The working mode of the mining working face commonly used at present is that the mining integrated machine, the reversed loader and the crossheading belt conveyor are sequentially overlapped and matched with each other. The reversed loader after the mining all-in-one machine mostly adopts a scraper conveyor or a cantilever lapping truss type transfer conveyor; the components of the scraper conveyor are heavy, time and labor are wasted in carrying and installation, the running resistance of the scraper conveyor is large, the noise is large, the consumed power is large, and the electric energy loss is serious; cantilever overlap joint truss-like transport conveyer afterbody and the connection of encorbelmenting of mining all-in-one, fuselage section part is encorbelmented, because receive the section bar and bear the holding power restriction, 36 meters of maximum length, and the freight volume is less, can't satisfy the all-in-one large distance of mining and tunnelling requirement, and truss occupation space is big, the single section weight is big, narrow and small space installation transport in the pit of being not convenient for, and above-mentioned two kinds of elevating conveyor all can't realize the autonomous movement of whole belt feeder, all need artificially or external force traction can realize removing.

The other type is that the self-moving tail is adopted, and the tail part is moved through a complex hydraulic device, so that the device has the advantages of large volume, large dead weight, complex control system, large installation and maintenance workload, low moving speed and the like, and the working efficiency of the fully mechanized coal face is also influenced. Tradition cisoid belt feeder stores up device tow frame and adopts the tow car structure, and whole tow car weight is supported by bottom wheel frame, therefore tow car weight receives the restriction, and the tow car height is shorter, and the sticky tape number of piles that can the bearing is less, causes to store up to take length and receives the restriction, and general cisoid conveyor stores up takes length about 200 meters, stores up to take length shorter, can't satisfy the requirement of high-efficient tunnelling in the pit.
