本装置是用来保护单绳双容器提升机容器卡在井筒任一点而引起松绳危险的,在松绳的同时,可在运行的罐笼中沿监视钢丝绳向提升机司机发出松绳危险信号。此装置既可用于深度300m,工作间断面2.1m~2的竖井,也可用于深度500m 以上、工作间断面3m~2以上的竖井。此装置系由张力传感器和监视钢丝绳组成。张力传感器安装在矿井提升机的井架上,绳轮1和2固定在井架上的一个金属架上(见图),而装有配重4的绳轮3则安装在导轨5上。绳轮上备有监视钢丝绳6(绳径4～10mm),其两端分别连接到各自的
The device is used to protect the single-rope double container hoist container stuck at any point of the wellbore and cause the risk of slack rope. At the same time of the slack rope, the danger signal of slack rope can be sent to the driver of the hoisting machine along the monitoring wire rope in the running cage. The device can be used for the depth of 300m, the cross-section 2.1m ~ 2 vertical shaft can also be used for more than 500m depth, the workroom section 3m ~ 2 above the shaft. This device is composed of tension sensor and monitoring wire rope. The tension sensor is installed on the derrick of the mine hoist. The sheaves 1 and 2 are fixed on a metal frame on the derrick (see the figure), and the sheave 3 with the counterweight 4 is mounted on the guide rail 5. The rope wheel is equipped with a monitoring wire rope 6 (rope diameter 4 ~ 10mm), the two ends of which are respectively connected to the respective
