Abstract: With the development of science and technology, the endless rope winch and related supporting facilities have been continuously improved, and the technical level has been greatly improved, however, the endless rope winch still needs to solve the problems of elastic rope and detachment. This paper first explained the problems existing in the rope pressing device of the endless rope winch, and then analyzed the force of the original rope pressing device of the endless rope winch, and on this basis, proposed measures to solve the disadvantages of the rope pressing device. Studies have shown that the new rope pressing device effectively reduces the phenomenon of rope winches and other phenomena, improves transportation efficiency and the service life of the device, and is worthy of popularization and application in mines.

現阶段,工作面产能持续提高,很多综采装置应运而生,其中,无极绳绞车在辅助矿井运输方面起到重要作用[1-2]。众所周知,矿井环境恶劣,作业条件具有很大的不确定性,虽然无极绳绞车的相关参数能够满足运输要求,但在实际工作中受限于巷道没有较大的竖曲线,运输时,钢丝绳张紧力较大,这样就容易把钢丝绳弹出,对工作人员的安全造成威胁。如果钢丝绳被弹出很高,对顶板也会造成损坏,既增加了磨损程度,又加大了摩擦系数。如果压绳轮转轴失稳,也很容易致使压绳轮弹出,进而引发风险。因此,对矿井无极绳绞车压绳装置进行改进成为当务之急。
1 无极绳绞车压绳装置存在的问题
无极绳绞车是一种辅助运输系统,组成部分较多,主要有绞车、张紧装置、平拖轮组、主副压绳轮组和牵引钢丝绳等[3-5]。主压绳轮借助拉紧弹簧压紧,受到外力作用,弹簧会松开,使得主压绳轮组绳轮张开,副压绳轮组则不同,其在安装完后是固定的。……
