开滦唐山矿二号井提升机于1930年安装使用,采用双圆柱圆锥形滚筒,至今已运行80余年,制动系统老化严重,日常维修量大且困难。随着提升机自动化升级的要求,原制动系统达不到与之配套的要求,鉴于此井为区域唯一的交通井,为满足安全生产的需要,该矿决定对原有制动系统进行改造。1改造前状况该提升机为采用风动——重锤角移式制动系统,附带空压机供风,系统能耗高,噪声大;原制动器无二级制动功能,施闸时,一次将全部制动力矩施加在提升机上,对机械系统冲击较大,影响设备的使用寿命;传动系统为单线传动,传动机构为杠杆传动,任
Kailuan No. 2 Tangshan mine hoist installed in 1930, the use of double cylindrical conical drum, has been running for more than 80 years, severe aging braking system, the daily maintenance of large and difficult. With the upgrading of hoist automation requirements, the original braking system can not meet the requirements of the matching, in view of this well as the only traffic wells in the region, in order to meet the needs of production safety, the mine decided to transform the original brake system . 1 before the transformation The hoist is the use of wind - hammer angular displacement brake system, with air compressor for the wind, the system high energy consumption, noise; the original brake without secondary braking function, gate, Once all the braking torque applied to the elevator, the impact of mechanical systems larger, affecting the life of equipment; transmission system for the single-line transmission, the transmission mechanism for the lever drive, any
