铜川矿务局某矿主绞,系2JK-2/20型提升机,电动机串电阻减速方式,液压盘形闸制动。绞车道长度600m,坡度20°。绞车道上部距正常停车位置0.5m处,安装有防止过卷的开关,此开关距天轮45m,坡度5°,在深度指示器上还装有一套防止过卷的开关、减速警铃及2m/s的限速保护装置。正常提升是将下车场的煤车经绞车道拉到上车场,同时把上车场的空车下放到下车场。每钩正常提升载重量1吨的矿车8辆,绞车所用提升钢丝绳为6×7+1-26的绳。更新时间不到2个月,断绳部位在断绳前已查出在一个捻距内断2根丝,其断丝数未超过铜川矿务局某矿主绞,系2JK-2/20型提升机,电动机串电阻减速方式,液压盘形闸制动。绞车道长度600m,坡度20°。绞车道上部距正常停车位置0.5m处,安装有防止过卷的开关,此开关距天轮45m,坡度5°,在深度指示器上还装有一套防止过卷的开关、减速警铃及2m/s的限速保护装置。正常提升是将下车场的煤车经绞车道拉到上车场,同时把上车场的空车下放到下车场。每钩正常提升载重量1吨的矿车8辆,绞车所用提升钢丝绳为6×7+1-26的绳。更新时间不到2个月,断绳部位在断绳前已查出在一个捻距内断2根丝,其断丝数未超过《煤矿安全规程》?
Tongchuan Mining Bureau, a mine main stranding, the Department 2JK-2/20 hoist, the motor resistance reduction mode, hydraulic brake disc brakes. Winch driveway length 600m, slope 20 °. The upper part of the winch is 0.5m away from the normal parking position. A switch is installed to prevent over-rolling. The switch is 45m away from the steamer and has a grade of 5 °. The depth indicator is also equipped with a switch to prevent over-rolling, 2m / s speed limit protection device. The normal improvement is to get off the coal car through the winch to get on the yard, while the empty car on the yard to the next yard. 8 hooks for normal loading capacity of 1 tonne per hook, 6 × 7 + 1-26 rope for lifting winch. The renewal time is less than 2 months. The broken part of the rope has been found out in front of the broken rope with 2 pieces of wire cut in one twist. The number of broken wires does not exceed that of a mine of Tongchuan Mining Bureau, type 2JK-2/20 Hoist, motor series resistance deceleration mode, hydraulic brake disk brake.
