Rear scraper conveyor tail drive transmission

Abstract

The invention relates to a tail of a scraper conveyor at the rear part of a working face, and particularly relates to a tail drive transmission device for rear scraper conveyors. The tail drive transmission device comprises a motor (1), a speed reducer (2) and a tail sprocket shaft set (4) which are sequentially rotatablely connected, wherein the tail sprocket shaft set (4) is arranged on a tail (5); and the tail drive transmission device is characterized in that the motor (1), the speed reducer (2) and the tail (5) are basically arranged in a same straight line. After the tail drive transmission device is used, the problem that parallelly-arranged power parts of the tail of a rear scraper conveyor occupy a shoring space at the rear part of a transition support is solved, so that the transition support and a middle support can be designed to supports in a unified model, thereby simplifying the technological procedures of support increasing and decreasing implemented due to the length change of a working face; meanwhile, the end coal-placing effect is improved, the coal-placing capacity is improved, and the recovery rate of coal resources is further improved; and the distance between the centers of tails of front and rear scraper conveyors is consistent with the distance between the centers of the middle sections of the front and rear scraper conveyors, thereby reducing the hysteresis phenomenon of the tail of the rear scraper conveyor, and improving operating situation of the tail of the rear scraper conveyor.

Description

technical field [0001] The invention relates to the tail of the scraper conveyor at the rear of the working face, in particular to the driving transmission device for the tail of the scraper conveyor at the rear. Background technique [0002] Fully mechanized top-coal caving mining technology is one of the important and efficient mining methods for raw coal mining in thick coal seams in my country at present. , "Unstable" coal seams have obvious advantages in efficient mining. [0003] Such as figure 1 As shown, the arrangement of the tail power section of the scraper conveyor at the rear of the existing fully mechanized caving face is mainly parallel arrangement. There are many problems in the parallel arrangement that have not been fully resolved in the existing equipment matching, mainly in the following aspects: 1. The tail power part of the rear scraper conveyor is arranged in parallel, which occupies a large space at the rear of the hydraulic support, resulting in Th...

Problems solved by technology

There are many problems in the parallel arrangement that have not been fully resolved in the existing equipment matching, mainly in the following aspects: 1. The tail power part of the rear scraper conveyor is arranged in parallel, which occupies a large space at the rear of the hydraulic support, resulting in The structure of the tail support hydraulic support is different from that of the middle frame, forming a special transition frame; 2. The tail power part of the rear scraper conveyor is arranged in parallel, which is affected by the layout position and space of the tail drive part, resulting in the rear scraper conveyor When the actual arrangement is in operation, the tail of the machine is bent, which increases the running resistance of the rear scraper conveyor to a certain extent; 3. The tail power part of the rear scraper conveyor is arranged in parallel. When the working face is advancing, when the length of the working face When changes occur, the process of adding and reducing racks is complicated, the labor intensity of workers is high, and there are certain safety hazards at the same time
