摘要
为适应倾斜煤层开采的需要,结合淮南谢一煤矿巷道布置,研制了一台大倾角下运花纹带式输送机。该机有如下特点:(1) 为适应±25°左右的输送倾角,采用了人字花纹输送带及四节深槽承载托辊组;(2) 为防止下运飞车事故,研制了用电液比例阀控制的液压盘式制动器;(3) 为降低带强要求,合理布置了传动滚筒及中间直线摩擦驱动装置。
A steeply inclined downward running ribbed belt conveyor is developed according to the funnel layout at Xieyi coal mine in Huainan to meet the demand in coal mining with inclined coal bed. The conveyor features:1) application of herrinbone ribbed belt and deep troughing idler sets with 4 idlers to adapt to the conveying angle about ±25.2) hydraulic disc brake controlled by an electrohydraulic proportional valve to prevent overspeed accident during downward running3) rational layout of driving pulleys and intermediat friction driving unit to meet the needs of lower belt strength.
