兖州矿业(集团)公司济宁二号煤矿23上11综采工作面运输顺槽长1 420 m,落差47 m,坡度2～10°,平均6°。在接面生产调试过程中,发现运输顺槽输送带多处跑偏严重,掉煤较多。对该顺槽带式输送机综合治理后,运行状况明显好转。①调整H架及托辊、滚筒。重新拉线调整与输送带中心线不垂直的H架,垫挖整平阴阳部H架,保证机头、机身与机尾平、直、稳,在中间部分巷道变坡点处对H架加高,增大曲线半径,使输送带与托辊良好接触。调整中间部分托辊手把,使上托辊手把全部打
Yanzhou Mining (Group) Company Jining No.2 Coal Mine 23 to 11 fully mechanized mining face transport slot length of 1420 m, a drop of 47 m, the slope of 2 ~ 10 °, an average of 6 °. In the junction of the production and commissioning process, found that transport along the conveyor belt more serious deviation, out of coal more. The comprehensive management of the slot conveyor belt, the operating conditions improved significantly. ① adjust the H-frame and roller, roller. Reinforce the H-frame that is not perpendicular to the center line of the conveyor belt and dig the flat H-section of the yin-yang to ensure that the nose, the fuselage and the tail are flat, straight and steady, and the height of the H-frame is increased at the transitional point of the middle part of the roadway , Increase the radius of the curve so that the conveyor belt and the idler good contact. Adjust the middle part of the roller handle, so that the roller handle all hit
