Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, and in particular to a wheeled belt winding and cutting device. Background Technology

[0002] Coal, as a vital energy resource, plays a crucial role in industries such as power, steel, and chemicals. In coal mining and transportation, belt conveyors are the core equipment for material transport, offering advantages such as long conveying distances, large capacity, and high continuity. However, with the expansion of coal mining scale, the length and width of conveyor belts are constantly increasing. Traditional manual winding and belt breakage methods are no longer efficient enough to meet the demands and pose significant safety hazards.

[0003] Currently, conveyor belt winding operations in coal mines mainly rely on manual labor or semi-mechanized equipment, resulting in low efficiency. Traditional winding methods are labor-intensive, especially when handling large, wide conveyor belts, where insufficient winding capacity is a common problem. Furthermore, they are prone to damaging the conveyor belt, posing safety hazards. In addition, belt cutting operations typically employ manual cutting or fixed cutting machines, which are ill-suited for conveyor belts of varying thicknesses, leading to poor cutting accuracy. Moreover, existing winding equipment is mostly fixedly installed or requires additional traction devices, lacking flexibility and unable to adapt to complex working conditions.

[0004] Therefore, there is an urgent need to develop an efficient, safe, and mobile integrated belt winding and breaking equipment to improve the maintenance efficiency of coal mine transportation systems, while reducing labor costs and safety risks, and enhancing the economic benefits of coal production.
