摘要
煤矿井下开采过程中,架空乘人装置是常用的作业人员输送装置,能够提高人员的输送效率及安全性.为提高架空乘人装置的安全性,避免钢丝绳断裂造成的危险,设计了楔形结构的断绳抓捕装置.依据楔形滑块的自锁性实现对断裂钢丝绳的抓捕制动,经过计算可知,楔形滑块的倾角在小于13.6°时能够实现自锁.在此条件下,对不同倾角的楔形断绳抓捕装置的性能进行仿真分析,结果表明,楔形倾角越大则产生的应力值越小,有利于断绳抓捕装置的使用.
Abstract
In the process of underground coal mining,the overhead travelling device is a commonly used personnel transport device,which can improve the efficiency and safety of personnel transport.In order to improve the safety of the overhead travelling device and avoid the danger caused by wire rope breakage,a wedge-shaped structure of rope breakage catching device is designed.According to the self-locking of the wedge-shaped slider to achieve the broken wire rope catching brake,after calculation,it can be seen that the inclination angle of the wedge-shaped slider can achieve self-locking when the angle of inclination is less than 13.6 °.Under this condition,the performance of wedge-shaped broken rope catching device with different inclination angles is simulated and analysed,and the results show that the larger the inclination angle of the wedge is,the smaller the value of the resulting stress is,which is conducive to the use of broken rope catching device.
