Description

Technical Field

[0001] The utility model relates to the technical field of hoists, in particular to a multi-rope friction type mine hoist. Background Art

[0002] Mine hoist is the throat equipment of mine and occupies an extremely important position in mine transportation. Multi-rope friction hoist refers to mining machinery equipment used to lift minerals, personnel and materials. It is suitable for the hoisting system of vertical and inclined shafts in coal, non-ferrous metals, ferrous metals, non-metallic, chemical and other mines. It consists of a reducer, a main pulley device, an engine and other parts.

[0003] The reference patent (publication number: CN219860036U; publication date: 2023-10-20) discloses a multi-rope friction mine hoist, including a mounting base, an adjustment cavity and a reinforcement seat. The top of the mounting base is provided with an adjustment cavity, and a movable groove is provided on the inner wall of the adjustment cavity. A threaded rod is installed on the inner side of the adjustment cavity, and a movable block is sleeved on the outer side of the threaded rod, and the movable block is embedded in the inner side of the movable groove. A reinforcement seat is installed on the top of the movable block.

[0004] In the existing multi-rope friction mine hoist technology, a fixed friction wheel is usually used to directly contact the rope to achieve the lifting and lowering of heavy objects. However, after long-term operation, the traditional design often causes increased rope wear due to the direct contact between the rope and the friction wheel. Moreover, due to the limited contact area and insufficient friction, it is easy to cause sliding or deviation during the lifting process, affecting the stability and safety of the hoist. In addition, when the friction wheel is severely worn and needs to be replaced, the entire hoist usually needs to be disassembled on a large scale, which is not only time-consuming and labor-intensive, but also increases maintenance costs and downtime. At the same time, the rope layout in the traditional design is relatively messy and easily entangled with each other, further increasing the difficulty of maintenance and safety hazards. For this reason, the present utility model provides a multi-rope friction mine hoist. Utility Model Content
