近年来,出现了通过提高罐笼提升速度、增加罐笼和矿车载重量、以及增大矿车换车频度来提高罐笼提升能力的稳定发展趋势。与此同时,在矿车-阻车器-罐笼的狭窄范围内,时而发生罐笼提升事故,其原因之一是缺乏对罐笼中矿车阻车器的可靠监控装置。通过对许多矿山和矿井生产情况的研究确实可以看到提升设备都没有装设有效的联锁装置,从而导致在提升工作中哪怕出现不很严重的事故,也要给查找和分析事故带来困难。例如,使用由乌苏利斯基矿山设备制造厂成批生产的CA型阻车机构,由操作工在车场水平处以目视法观测矿车后轮组通过后阻爪向上凸出的情况来对罐笼中的矿车阻
In recent years, there has been a steady development trend of improving the cage lifting capacity by increasing the cage lifting speed, increasing the weight of the cage and the mine car, and increasing the frequency of changing the car. In the meantime, one of the reasons that cage crashes sometimes occur in the narrow range of tubs - car stoppers - cages is the lack of reliable monitoring of the car stop in the cages. Through the study of many mine and mine production conditions, it is indeed possible to see that lifting equipment is not equipped with effective interlocking devices, resulting in difficulties in locating and analyzing accidents even in the unlikely event of an uplift. . For example, using the CA-type stop-and-go mechanism mass-produced by the plant of Wusouli Mining Equipment Factory, the operator visually observed at the level of the yard visually the situation that the rear wheelset protrudes upward after the passage of the rear wheelset Cages in the car resistance
