Sample:

1: drum diameter of single drum brake type 2.5m, width of 2.0m single rope winding mine hoist type: JK2.5 * 2;

2: drum diameter is 3.5m, width of double drum disc brake type 2.1m single rope winding mine hoist type: JK3.5 * 2.1;

First, the main purpose and scope

JK series mine hoist is the basis of the people's Republic of China security industry standard AQ 1035-2007 the coal mine single rope winding hoist machine safety inspection standards "and the people's Republic of China National Standard GB / T 20961-2007 design and manufacture products. The product is suitable for coal, metal ore, non-metallic mine shaft or shaft lifting personnel, materials and equipment.

Hoist working conditions

Hoist installation in the air temperature of 0 DEG to 40 DEG C, relative humidity of not more than 85% (ambient temperature is 20 DEG C plus or minus 5 DEG C), altitude: not more than 1000m in the engine room, can prevent the liquid immersed inside the electrical appliances, no violent vibration, the bumps along the way, no corrosive gas environment. When altitude over 1000m, need to take into account the decline in air cooling effect and dielectric strength, the selection of electrical equipment should be design or using the drum winding wire rope layers according to the manufactory and user agreement

No more than the following provisions:

(1) the vertical lifting or lifting personnel and materials, 1 layers; designed for lifting materials, 2; DIV>

(2) inclined lifting personnel or lifting personnel in mine material, 2 layers; the 3 layer of material lifting. DIV>

(3) wire rope from the lower transferred to the upper threshold (equivalent to loop 1 / 4 length) must always check and wire rope mobile 1 / 4 loop position on a quarterly basis.

Warning:

(1) the hoist is used for gas, coal dust and other flammable and explosive gas!

(2) the hoist overload operation is strictly prohibited!

(3) forbidden overspeed, rolling blackouts!

Two, the structure characteristics and working principle

Lifting machine is mainly composed of the components of main shaft device, adjusting rope device (binocular), disc brake device, depth indicator, reducer, lubricating station, tachometer generator device, a shaft coupling, a motor, a control table, hydraulic system and electric control system etc..

Working principle: when to start the main motor, by the motor rotor low-speed coupling power will be transmitted to the gearbox high-speed shaft, through two-stage gear reduction, by the reducer of the driven shaft through the coupling transfer to the spindle apparatus. If changing the turning of the motor, the drum winding or loosen the wire rope, and lifting up and down from the container in the wellbore, periodic motion.
