铁法矿务局晓明矿新建副井JKM3.25×4(Ⅱ型)多绳摩擦轮式提升机,在1983年7月安装后,提升机的制动装置一直处于故障状态,工作制动闸动作时,受到多方面的阻力,使闸瓦与制动轮不能及时分离。提升机在施闸状态下起动运行,大大增加了提升机的运行阻力,使闸瓦和制动轮产生过热和磨损。为了改善上述情况,晓明矿将提升机制动系统的工作油压以12kg/cm~2提高到15kg/cm~2,效果并不明显,而且制动器的主要构件受力超过了图纸设计要求,直接威胁提升机的安全运行,影响了提升机早日投入正式运行使用。为了解决这个问题,我们经
Iron Law Mining Bureau Xiaoming new auxiliary shaft JKM3.25 × 4 (Ⅱ type) multi-rope friction wheel elevator, installed in July 1983, the hoist brake has been in a fault state, work brake Gate action, subject to a wide range of resistance so that brake shoes and brake wheel can not be separated in time. The hoisting machine starts running under the state of opening sluice, which greatly increases the operational resistance of the hoisting machine, causing overheating and wearing of the brake shoe and brake wheel. In order to improve the above situation, Xiao Ming mine hoist hydraulic brake system to 12kg / cm ~ 2 to 15kg / cm ~ 2, the effect is not obvious, and the main components of the brake force exceeds the design requirements of the drawings, direct Threatening the safe operation of the hoist, affecting the hoist put into operation as soon as possible to use. In order to solve this problem, we have
