断绳防坠器是竖井单绳提升罐笼最重要的安全保护装置。
In order to theoretically resolve the problem of safety and reliability of the rope parachute gear in the mine hoisting,the mechanical models of the brake-rope\'s states(tensioning and relaxation) were established,considering the buffer rope\'s states of hauling out or not.
为了从理论上解决罐笼因坠落而被绳式防坠器制动过程时的安全可靠性问题,针对防坠器缓冲绳未被抽出及被抽出2种情况,建立了制动绳张紧及松弛力学模型,给出了缓冲绳被抽出的条件、罐笼被抓捕到制动绳处的制动减速度和制动绳动张力表达式。
