摘　　要：为了防止带式输送机发生纵向撕裂,满足煤矿的多搭接点应用需求并适应斜井和平巷胶带机的2种布置方式,设计了一种新型的带式输送机“T”字型纵撕保护装置。通过分析“L”型纵撕保护的动作原理和实际应用中的缺点,结合斜井布置胶带机安装纵撕保护后频繁误动作的现场实际情况,设计出“T”字型的结构配合使用双点动作传感器,同时满足承接2种落料效果和触发方式,从结构上和动作方式上提高胶带机纵撕保护的可靠性、稳定性、灵敏性,有效降低保护的误动作率,不仅可以提高胶带机开机率也可有效减少带面发生纵向撕裂后造成的损失。该装置在神东煤炭集团石圪台煤矿主斜井胶带机投入使用后,保护效果能够满足设计预期和应用需求。In order to prevent the belt conveyor from longitudinally tearing,especially to meet the needs of the application of multi-lap points in coal mines,and to adapt to two layout of the inclined shaft and roadway belt conveyor,a reliable protection against longitudinally-tearing of the belt surface is required.This paper introduces a new type of belt conveyor’s longitudinally-tearing prevention device.Through analyzing the“L”-typed longitudinally-tearing prevention action principle and practical application shortcomings,based on the analysis of the actual situation of frequent misoperation after longitudinally-tearing prevention is installed on the inclined shaft belt conveyor,a“T”-typed structure with the use of double-point motion sensor is designed to meet the requirements of two kinds of blanking effect and initiation mode,improve the reliability,stability and sensitivity of longitudinally-tearing prevention of belt conveyor from structure and action mode,and effectively reduce the false operation rate of prevention.The device can not only improve the startup rate of the belt conveyor,but also effectively reduce the losses caused by the longitudinally-tearing of the belt surface.
