摘要
针对煤矿刮板输送机经常出现断链事故,为高效、便捷的完成接链工作,本文提出建立专门的接链装置。论文首先对刮板输送机链条的预紧力和负载张力进行了理论计算分析,为后续的设计提供基础;接着针对掘进工作面常用的SGB-40T刮板输送机,本文提出液压式和机械式两种接链装置,并分别对各自的结构和工作原理进行了介绍。
In view of the broken chain accident in coal mine scraper conveyor and aimed to finish the chain work efficiently and conveniently, the paper proposes the establishment of special chain device. Firstly, the theory of pre-tightening force of scraper conveyor chain tension and load are calculated and analyzed to provide the basis for the subsequent design, then it proposes the hydraulic and mechanical type chain de- vice in connection with SGB-40T scraper conveyor, and the structure and working principle of the resnective are introduced..
