Self-movable foot end of belt conveyer

Abstract

The invention relates to belt conveyer self moving discharge end. It includes middle frame, head end frame, tail end frame, float frame, walk dolly, hydraulic mechanism, maneuvering valve set, column oil cylinder, passage oil cylinder, level oil cylinder, float cylinder, carrying roller assembly, screw drum, slide shoe, slide seat, and base seat. The middle frame, head end frame, tail end frame, float frame, and the walk dolly are connected wholly. The float frame can make the self moving discharge end be transition join with the belt conveyer. The tail end frame adopts left-right screw drums to squeeze out the sewage. While self moving, the joint between the walk dolly and the lower of the loading mechanism end is used as fulcrum; the slide seat, base seat, column oil cylinder are used as support to process oil cylinder stretching to make whole machine move forward that once self moving travel can reach 2.7m. The column oil cylinder can adjust the height for the complete machine. Thus the invention has the advantages of compact structure, large force, safe flameproof, stable and reliable etc.

Description

technical field [0001] The invention relates to a self-moving tail of a belt conveyor, which belongs to the technical field of supporting devices for underground transportation equipment in coal mines. Background technique [0002] Belt conveyors have been widely used in large and medium-sized coal mines, especially in high-yield and high-efficiency working faces. The tail of the belt conveyor is connected with the trough loader. Because it is transported and reloaded in the narrow tunnel underground of the coal mine, the smooth connection and rapid relocation of the transfer machine have become a major problem. [0003] The coal mined by the shearer must be transferred to the belt conveyor through the trough bridge transfer machine before it can be transported out of the ground. The transfer machine and the belt conveyor must be connected through the tail, in order to better complete the belt conveyor. In order to ensure the smooth connection of the trough loader, a device...

AI Technical Summary

Problems solved by technology

At present, there are many disadvantages in the tail of the belt conveyor. The main frame of some tails adopts an integral welded structure. Mobile; the tail of some belt conveyors adopts a separate assembly structure of parts, which requires a large number of connecting parts, the structure is complex, the assembly requirements are high, and the coal mine is humid, the connecting parts are easy to rust, difficult to disassemble and assemble, and inconvenient to maintain; some The tail of the belt conveyor cannot be isolated from the upper and lower belts. When used in conjunction with a reloader, the coal leakage when the reloader unloads coal will fall to the lower belt, which is difficult to clean and has many safety hazards; some belt conveyor tails The bearing point is flat, and the coal material cannot be centered, which will easily cause the belt to deviate and cause abnormal wear of the belt; some belt conveyors cannot move their tails by themselves, and move by pulling, which is slow and difficult
