吊桥与卷扬机电气联锁 我矿东采场付斜井卷扬机是混合提升系统,斜井通过吊桥与井口水平相连接。往往人车由下面的中段运行快到井口位置时,而井口吊桥尚未吊起。对运送人员的安全造成威胁。为此,我们将吊桥与卷扬机的电气控制之间增设联锁装置,即不论是人车或矿车在斜井内运行时,只要吊桥没有吊起来,卷扬机就不能开动,同时还向并口信号工发出报警信号。电控原理见图1。
Suspension bridge and winch electrical interlock I mine East stope paid inclined shaft winch is a hybrid lifting system, inclined shaft through the suspension bridge connected with the horizontal wellhead. Often people and vehicles from the middle of the following run to the wellhead location, while the wellhead suspension bridge has not yet been hoisted. Threatening the safety of transporting personnel. To this end, we have added an interlock between the electrical control of the drawbridge and the winch. That is, no winch can be started as long as the man or the car runs in the inclined well, as long as the drawbridge is not hoisted, and the parallel signal generator is also issued Alarm. Electronic control principle shown in Figure 1.
