摘　　要：对大块物料或长条形异物卡压引起带式输送机纵撕事故机理进行了分析,设计了一种新型超前防压卡纵撕保护装置,该装置采用双作用综合判定,选用的关键器件简单、可靠,当发生压卡输送带条件时便立刻停机保护,避免了发生撕带引起的损失,可起到超前保护作用。Analyses the mechanism of longitudinal tip of the belt conveyors. A new leading protection device was designed for the anti - longitudinal tips belt caused by the press and jam of big material. The device has double- acting decision and its main components are simple and reliable. The leading protection can be put into effect when the press and jam of big material takes place.
