试论发展我国刮板运输机的技术途径

Technical Approaches for Developing the AFC in China

刮板运输机是机械化工作面的关键设备之一,特别是在综合机械化工作面,它除了完成运煤和清理机道浮煤外,还是采煤机运行的轨道,液压支架前移的基点。在运输机上还设有卷放电缆、水管装置和采煤机牵引链张紧装置或无链牵引的齿轨,有的还安设通迅控制系统及照明装置等。通过刮板运输机将采煤机、刮板运输机和液压支架组成一个整体,使采煤工艺过程全部实行机械化。因此,刮板运输机质量的优劣、服务年限的长短和性能的好坏,对机械化工作面的主要技术经济指标都有很大影响。

This Paper reviews briefly the research and development of AFC in China. It is considered that attention should be paid to the following three aspects: 1. R & D of single, twin inboard chain AFC. 2. R & D of more powerful, high strength and capacity AFC, and 3. Improving the quality and service life of the components. Finally, some suggestions on the R & D of AFC in China are proposed. The author holds that the tendency of paying attention only to the design and not to the development of AFC should be overcome; that professional cooperation between manufacturing factories should be promoted and that specialized fabricating factories should be set up.
