Mine hoists are widely used in the hoisting systems of shafts and inclined shafts in mines such as coal, non-ferrous metals, ferrous metals, non-metals, chemicals, etc. They are used to lift minerals, lift personnel, materials and equipment, etc. They are the throat of mine system equipment. It can also be used as other traction and transportation equipment.

The mine hoist is one of the leading products of our company. It has experienced more than 40 years of continuous exploration and research in the hoist industry and has achieved fruitful results. Zhongshi Luoyang Heavy Machinery Co., Ltd. (formerly Luoyang Mining Machinery Factory) has relatively complete testing equipment and means, and a group of highly skilled scientific research and technical personnel, including engineers, professors and provincial-level cross-century technical talents, specializing in single rope winding. Research and new product development on equipment technologies such as hoists, multi-rope friction hoists, dam-crossing hoists, well-drilling hoists, tension winches, and explosion-proof winches. The company has obtained the applicable scope of coal safety certification for single rope and multi-rope mine hoists with a diameter of 2m-5m.

working principle

A closed steel wire rope with a container hanging in the middle is wrapped around the drum. When the TV drives the drum to rotate, the container is lifted and lowered through the friction between the wire rope and the drum. Speed ​​regulation is achieved through electrical transmission. The disc brake is controlled hydraulically and electrically. Realize braking; realize the depth indication of the container through various position indication systems; monitor and protect the entire machine through a mechanical, electrical, and hydraulic combined system composed of various sensors and control components; realize lifting inside the machine through computer and network technology , external information transmission.

Technical Parameters

Friction well tower elevator

Friction floor hoist

main feature

1. According to the performance parameter requirements of the elevator, it can be configured with single or double disc friction wheels. The friction lining of the floor-standing friction elevator is a double rope groove and is equipped with a rope pulling device. The shaft tower type is a single rope groove;

2. Under oil-free, water-spraying or special grease conditions, the friction lining can be made of Nissan GM-3 or GDM-326 high-performance materials, with friction coefficients ≥0.25;

3. The crown wheel and guide wheel device are arranged eccentrically, and the rim is equipped with a polymer wear-resistant material liner. Reduce the wear of wire rope;

4. It adopts a rear disc brake of the oil cylinder, combined with electric and hydraulic control. The hydraulic station is divided into two types: medium pressure, medium pressure and high pressure. The medium-pressure hydraulic station has two modes of constant braking torque, electrical delay and hydraulic delay secondary braking; the medium and high-pressure hydraulic station has two modes of constant deceleration and constant braking torque, two-level braking, and can be equipped with pressure relays and pressure sensors. and pressure transmitters;

5. Speed ​​measurement transmission and backup protection, supporting components such as brake disc deflection monitoring device, wire rope sliding monitoring device, car slot device, special tools, etc.;

6. There are four types of consoles to choose from, all of which use integrated signal lights. Two are table-type, equipped with a new integrated operating handle, one of which has a computer with its own LCD display; two are split-type consoles, equipped with There is a digital depth indicator. All have special countertops for industrial TVs or computers, printers, etc.;

7. Equipped with mine hoist network control and remote diagnosis system;

8. The WSM-3 new environmentally friendly asbestos-free brake shoe is used. Its superior performance ensures the safety of the disc brake.
