Product features, main uses and scope of application:
2JK series mine hoist It is designed and manufactured according to the safety production industry standard AQ 1035-2007 safety inspection specification for single rope winding mine hoist, GB / t20961-2007 single rope winding mine hoist and enterprise standard Q / hbwf003-2016 single rope winding mine hoist.
It is suitable for coal mine, metal mine and non-metallic mine ground or underground inclined roadway and shaft as lifting material and personnel.
When starting the main motor, the motor rotor transmits the power to the high-speed shaft of the reducer through the elastic coupling. After being driven and decelerated by the reducer, the passive shaft of the reducer is transmitted to the main shaft device through the gear coupling. If the rotation direction of the motor is changed continuously, the drum can be wound or the wire rope can be loosened, so that the hoisting container can go up and down periodically in the shaft Sports.
The single rope winding mine hoist takes the electric motor as the power source, transmits the power to the winding drum of the steel wire rope through the reducer to realize the lifting and lowering of the container, realizes the speed regulation through the electric drive, the disc brake is braked by hydraulic and electrical control, the depth indication of the container is realized through the position indication system, and the control elements of various sensors and speed measuring generators are used, Constitute a security protection system.
Representation of product model:
The indication method of hoist model shall comply with the provisions of MT / T 154.8-1996 "preparation method of coal mine machinery product model".
The lower safety factor of steel wire rope is as follows:
1. 9 times for lifting personnel; 2. Lifting personnel and materials (9 times for lifting personnel, 9 times for mixed lifting, 7.5 times for lifting materials); 3. 6.5 times for lifting materials.
2. The ratio of the diameter of the drum to the diameter of the steel wire rope of the mine hoist in the mine shall not be less than 80 times; the ratio of the diameter of the drum to the diameter of the steel wire rope of the hoist in the underground mine shall not be less than 60 times.
III. The number of winding layers of wire rope on the drum shall meet the following requirements:
1. Floor 1 for lifting personnel or lifting personnel and materials in the shaft; floor 2 for lifting materials;
2. There are 2 floors for lifting personnel and materials in inclined shafts; 3. For lifting personnel and materials during well construction, 2 floors.
