Description

Technical Field

[0001] The utility model discloses a small pneumatic walking device suitable for a light monorail suspended pipeline, belonging to the technical field of auxiliary equipment in coal mines. Background Art

[0002] When the fully mechanized mining face in an underground coal mine is advanced, a large number of cables and hydraulic pipes must be withdrawn synchronously with the withdrawal of fully mechanized mining equipment such as shearers, transfer machines, and scraper conveyors. A large proportion of coal mine units suspend these power cables and hydraulic pipes on pulley assemblies. The pulley assemblies, which use lightweight I-beam monorails as tracks, are pulled back simultaneously with the mining face under the drag of the unit. However, due to the lack of an independent power source, the pulley assemblies cannot actively move along the I-beam monorail tracks. This is especially prone to siltation and even runaway in roadways with uphill and downhill slopes, making it difficult for the fully mechanized mining equipment to move forward. In the event of overload, the pipelines may break, posing a significant safety hazard and seriously affecting production efficiency. There are some existing electro-hydraulic power cable and hydraulic pipe devices, but they are large in size, heavy in weight, and have complex electro-hydraulic systems. They cannot meet the technical requirements of lightweight I-beam suspension equipment. Furthermore, multi-point suspended pipelines are more suitable for synchronous or asynchronous power assistance of many units and cannot utilize compressed air power sources, which have lower safety requirements, are more convenient, and have lower power requirements in underground coal mines. Therefore, a pneumatic walking device suitable for lightweight monorail suspended pipelines is needed. Utility Model Content
