矿井提升机的制动力应根据重载下放最大载荷时确定的制动安全系数进行选择。但是从矿井提升机安全运转观点看,在大多数提升工况下,快速过力施闸是不允许的,因为斜井重载上提时,会造成容器冲击钢丝绳,而对摩擦轮提升机,则将导致钢丝绳沿摩擦轮滑动。完全靠司机的熟练操作来消除安全制动和工作制动中的容器冲击钢丝绳或摩擦提升钢丝绳的滑动是不可能的,因为在司机误操作时(猛烈地施闸),必然发生上述两种险情。很显然,这种由于司机操作失误引起的
The braking force of the mine hoist should be selected according to the braking safety factor determined when the maximum load is released. However, from the mine hoist safe operation point of view, in most of the lifting conditions, the rapid force gate is not allowed, because the inclined shaft heavy load on time, will cause the container to impact the rope, and the friction wheel hoist, It will cause the rope to slide along the friction wheel. Completely rely on the driver’s proficiency in the operation to eliminate safety Braking and working Braking in the impact of the rope or friction rope slippage is impossible, because the driver misoperation (violent gate), the inevitable occurrence of the above two kinds of dangerous . Obviously, this due to driver error caused
