以前的斜井提升机松绳信号是采用拉簧信号器作开关元件,安装情况如图1所示。这种松绳保护装置,很不适应斜井提升机的需要,因为斜井提升机在甩车过程中,尤其是在上部甩车场甩车时,卷筒上的钢丝绳都程度不同的存在松绳现象。当卷筒上的钢丝绳松到一定程度时,松下的钢丝绳就会压在拉簧信号器的牵引钢丝绳上,几乎每次 Previous incline elevator slack rope signal is the use of tension spring signal for switching components, the installation shown in Figure 1. This slack rope protection device is not suited to the needs of inclined shaft hoist, because the inclined shaft hoist in the process of turning off the car, especially in the upper rejection yard rejection car, the wire rope on the drum are different levels of loose rope phenomenon. When the reel on the loose rope to a certain extent, the Panasonic rope will be pressed on the tension spring signal traction rope, almost every time
