Mine Hoist Disc brake


Hoist plays an important role in lifting personnel, materials and coal. The safe operation of the hoist directly affects the safety of underground personnel and coal production. The working reliability of the mechanism is an important link to ensure the safe operation of the hoist.

Disc brake is the hydraulic actuator applied in mine hoist brake system, mainly used for JTP single cylinder 1.2m, 1.6m, 2m, 2.5m, 3M mine hoist brake device. In the elevator when starting the hydraulic station output pressure oil on the brakes, lifting machine to work, work brake, hydraulic station according to the condition of increasing or decreasing pressure, brake will provide braking force on the contrary, in the case of accidents, the hydraulic pressure station to residual pressure, actuator with maximum braking force in the shortest time to hoist parking
The hydraulic station is safe and control unit of mine hoist important, it and the disc brake has a complete set of braking system, provide pressure oil can be adjusted for disc brake, the braking torque for different hoist, hoist the normal operation, adjustable speed, parking mine. In any state of the accident, the disc brake can quickly reduce the oil pressure to a predetermined value, after the delay, the disc brake all the oil pressure quickly return to zero. Make the hoist system in full braking state.

The lifting mechanism has two main types
1 block brake: mainly used for the old KJ and KJA series hoist, according to its structure is divided into angular, translational, integrated and so on
2) disc brake: nearly 20 years transplanted to the mine hoist brake machine, with small inertia, quick action, high sensitivity, braking torque advantage of good regulation, at present most of the disc brake, especially in multi rope friction hoist, almost all using disc brakes.

The Working principle of disc brake

The disc brake is produced by the disc spring, and the brake is pressed by the hydraulic pressure. When the braking state is used, the spring force of the disc spring group is used for the brake. When the oil pressure is reduced to zero (the gate process), the spring force generated by the compact disc spring pre mid shaft and disc spring push studs to the brake shoe wear compensation effect, positive spring force is applied the brake shoe and the brake disc brake is attached to pressure, thereby restricting the brake disc rotation trend. The cylinder pressure chamber filled with oil (boost brake process), when the oil pressure is gradually increased to the working pressure, the piston and the brake shoe connected by oil pressure, overcome the pretightening force of disc spring and spring compression caused the rearward displacement of piston, through a large hollow stud, drive shaft, brake disc spring set wear compensation stud and drives the brake shoe after the shift, a gap is formed between the brake shoe and the brake disc, thereby lifting the braking effect on the positive pressure of the brake disc

The Main features of disc brakes

1) the effective area of hydraulic pressure is large, and the pressure of the hydraulic system is medium and high pressure.
2) of the hydraulic cylinder piston and the brake shoe is not rigid connection.
3) compensation adjustment of brake shoe and brake disc clearance convenient, only by screwing the brake wear compensation stud can be realized, and will not change the initial preload disc spring, brake shoe replacement is also very convenient.
4) brake materials with high friction coefficient, good wear resistance.
5 brake pairs of symmetrical use, the brake disc and drum will not produce additional lateral load.
6 in normal braking, the brake can be divided into two groups, first put into a group of work, after a certain interval of time, and then put into the second group, to achieve a two brake.

The advantages of the rear cylinder disc brake are: compact structure, small size, adjustable performance, sensitive action, light weight, small inertia, high safety, good versatility and so on. When used in pairs, the main shaft does not bear the additional axial force, but also can be used in classification
