JKM Multi-Rope Mine Hoist Explosion-Proof High Quality Support Customization
Adopting various types of drums, including integral, two-piece, and four piece types;
1.The drum rope groove adopts processed spiral rope groove, folded line rope groove, or spiral rope groove pressed with wood lining and plastic lining, and a steel rope transition device is set between the ropes;
2.Adopting a rear mounted disc brake with oil cylinder and electric hydraulic joint control; Hydraulic stations are divided into two types: medium low pressure and medium high pressure. There are two types of medium and low pressure hydraulic stations: constant braking force electrical delay and hydraulic delay two-stage braking; There are two forms of medium and high pressure hydraulic stations: constant deceleration and constant braking torque two-stage braking. The hydraulic station can be equipped with pressure sensors and pressure relays;
3.The spindle and drum are connected by flat high torque friction connection;
4.A signal monitoring device composed of a photoelectric encoder, a self aligning machine, and a low-speed Chilean speed measuring generator, with complete monitoring and protection functions such as overspeed, over winding, depth indication failure, brake shoe wear, spring fatigue, etc.
Advantages
Lifting height is not limited: The lifting height of the multi-rope friction hoist is not limited by the width of the drum, and is suitable for deep well hoisting.
Equipment size and weight reduction: Since multiple wire ropes bear the terminal load together, the diameter of the wire rope can be reduced, which leads to a significant reduction in the diameter of the friction wheel, and the size and weight of the entire hoist will be reduced.
Improved safety: Multiple wire ropes bear the load at the same time, which improves the overall safety; and the possibility of multiple wire ropes being broken at the same time is extremely small, so no fall arrester is required.
Disadvantages of multi-rope friction mine hoists include:
Complex maintenance: The suspension, replacement, adjustment and maintenance and overhaul of multiple wire ropes are complicated. When one wire rope is damaged, all wire ropes need to be replaced.
