Problems solved by technology

After the frame is moved, the filling material transfer machine needs to be connected to the end of the filling material conveyor in time. At this time, the maintenance workers at the end need to enter the gob area to work. The labor intensity is high and the work efficiency is low, which has a certain impact on the personal safety of the workers. security risks

Abstract

The invention relates to an end supporting, filling and transshipping system of a coal face. The system comprises an end hydraulic bracket body frame and end hydraulic bracket sub-frames, wherein the end hydraulic bracket sub-frames are arranged on the both sides of the end hydraulic bracket body frame and alternately move with the end hydraulic bracket body frame; a filling material conveyor anda filling material transshipping machine capable of moving along with the end hydraulic bracket body frame are arranged in the end hydraulic bracket body frame; the front part of the filling materialtransshipping machine is overlapped with a rubber belt conveyor arranged in a travelling roadway, and the material discharging end on the back part of the filling material transshipping machine is overlapped with the filling material conveyor; the bottom of the filling material transshipping machine is provided with a front adjusting oil cylinder and a back adjusting oil cylinder which are hingedto a base; and the filling material transshipping machine is provided with a telescopic transshipping machine inner frame and a telescopic winch for dragging the transshipping machine inner frame. The end supporting, filling and transshipping of the coal face are integrated to carry out the self-moving reinforcing and supporting, solid filling and synchronic transshipping on the end of the coal face so that the work amount and labor intensity of the supporting, filling and transshipping of workers on site are reduced, the working efficiency and the effect of filling and transshipping are enhanced, and the unsafe factors are reduced.

Description

technical field [0001] The invention relates to a support filling and reloading system, in particular to a coal mining face end support, filling and reloading system suitable for end support, end filling compaction and filler reloading of coal mining working faces in mines, belonging to coal mines field of mechanical technology. technical background [0002] In recent years, comprehensive mechanized filling mining technology has developed rapidly, and electro-hydraulic control hydraulic supports have been widely used, which has greatly improved the level of coal mining technology. However, the end of the coal mining face is still maintained with a cross top beam and a single pillar. During the process of feeding, pushing, and moving the end of the coal mining machine, the roof support work at the end of the working face is very cumbersome. The labor intensity is high, and the waiting time for the shearer to stop at the end is long. What is more serious is that the risk of m...
