JKMD-3.5X4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JKMD—3.5×4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。

Abstract
Currently many of our coal mine has turned to deep mining. Mine coal upgrading equipment as the key equipment holds an important position in mechanized production of the mine. The brakes are one of the important components of a direct bearing on Hoist the safe operation of equipment.
Multi-rope friction hoistwith small size, lightweight, safe, reliable, and strong ability to upgrade apply to the deeper mine hoist. In this paper, the braking system for four-rope friction round hoist have been designed.
In the hoist brake selection process, because in recentyears disc brake is used in the new brakes It's unique strengths and good safety performance recognized by the majority of users. Especially in the light of the hydraulic control system and the PLC, Hydraulic System and PLC super performance of the disc brake provides a tremendous platform for thework. Brake disc braking force and rely on the fuel tank filledwith oil that drives the piston to compress spring to achieve Disc.
Hydraulic disc brakes as the latest development of a brake,which has many advantages. Therefore it in a modern aircraft types to upgrade gainwider application. It is the braking force,flexibility stability,high sensitivity; on production safety is of great significance.Multi-rope friction hoist take use of friction to bringwire-rope alongwith leading-wheel turning,which is caused by the effect ofwire-rope and the friction liner in the leading-wheel, so as to achieve containers to upgrade and descending. The design is the JKMD-3.5×4 friction hoist, and the features are: spindle device structure design,strength and rigidityverification& calculation; calculation ofwire Rope choice; decision of transmission parameters and the main motor choice& calculation; raising height calculation andverification; checking of anti-skid conditions.
Key Words:Hoist; Multirope friction; Brake; Anti-skid conditions; Hydraulic drive
