由于KJ型、仿苏БМ型旧式提升机的制动系统为单缸制动,制动力矩不足,又无二级制动,所以常发生制动闸失灵造成重大设备和人身事故。为弥补上述旧式提升机制动系统的缺陷,确保矿井提升安全,现已有些局矿为副井旧式提升机加装了小抱闸,用作大闸的后备闸。徐州局1986年大部分矿加装了小抱闸,我局1986年已全部到货,1986年底已有三个矿的副井提升机加装了小抱闸。安装使用小抱闸存在一个共同的问题是制动系统油路控制不理想。采用原生
Due to the KJ type, the brake system of the old Soviet-like БМ hoist is a single-cylinder brake with insufficient braking torque and no secondary brake, so frequent brake failure causes major equipment and personal accidents. In order to make up for the shortcomings of the braking system of the old hoist and ensure the safety of the mine, some local mines have installed a small brake for the old hoister of the auxiliary shaft to serve as a backup brake of the brake. Xuzhou Bureau 1986 most of the mine to install a small brake, our bureau has all arrived in 1986, by the end of 1986 has three mine auxiliary shaft hoist equipped with a small brake. A common problem with the installation of a small brake is that brake system oil circuit control is not ideal. Native
