井下胶带输送机在运行中,常发生跑偏、堆机头、断带、撕带、断绳、打滑及零部件损坏等故障。尤其是胶带打滑不仅引起堆机头和损坏胶带,甚至酿成火灾。本文着重介绍几种易于推广使用的(均是通过鉴定的)胶带机保护装置。一、胶带机几种保护装置简介目前国产胶带机对撕带、断带(倾角较大飞速下滑)、断绳等事故还没有行之有效的保护办法。但对打滑、煤位、跑偏保护已通过鉴定,大致可分以下几个类型。 1.在JDB型电机综合保护器的基础上增 Downhole belt conveyor in operation, often deviation, heap head, broken belt, tear tape, broken rope, slipping and parts damage and other failures. In particular, tape slippage not only caused the stack head and damaged tape, and even caused a fire. This article focuses on several easy to promote the use of (both by identification) tape machine protection device. First, the introduction of several protective tape device At present, the domestic tape machine on the tear tape, broken belt (dip rapid decline), broken rope and other accidents there is no effective protection. However, slippery, coal, run-off protection has been identified, roughly divided into the following types. 1 in JDB motor protection based on the increase
