JKMD4×4多绳摩擦式提升机的设计
摘要
目前我国许多煤矿矿井已经转向中、深部开采,矿井提升设备作为煤矿的关键设备,在矿井机械化生产中占有重要地位。制动器是提升的重要组成部分之一,直接关系着提升机设备的安全运行。
多绳摩擦提升机具有体积孝质量轻、安全可靠、提升能力强等优点,适用于较深的矿井提升。本文利用大学期间所学课程针对多绳摩擦轮提升机,对其滚筒和制动系统进行设计。
在对提升机的制动器选型过程中,因盘式制动器是近年来应用较多的一种新型制动器,它以其独特的优点及良好的安全性能被广大用户认可,特别是在结合了液压系统和PLC控制之后,液压系统和PLC超强的控制性能为盘式制动器的应用提供了巨大的工作平台。制动盘的制动力,靠油缸内充入油液而推动活塞来压缩盘式弹簧来实现。
液压盘式制动器作为最新一种制动器,具有许多优点,所以它在现代多种类型提升机中获得广泛的应用。它具有制动力大、工作灵活性稳定、敏感度高等特点,对生产安全具有重要意义。
多绳摩擦提升机是利用钢丝绳与主导轮上的摩擦衬垫之间的摩擦力带动钢丝绳随着主导轮一起转动,从而实现容器的提升和下放。本次设计为JKMD4×4多绳摩擦提升机的设计,设计内容主要有:主轴装置的结构设计和强度及刚度较核计算;钢丝绳的选择计算;传动系统参数确定及主电动机的选择计算;提升高度的计算及校核;防滑条件等验算。
