多绳摩擦式提升机设计

多绳摩擦式提升机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小、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。关键词：提升机；多绳摩擦；制动器；设计；液压传动。Abstract Currentlymanyofourcoalminehasturnedtodeepmining.Minecoalupgradingequipmentasthekeyequipmentholdsanimportantpositioninmechanizedproductionofthemine.ThebrakesareoneoftheimportantcomponentsofadirectbearingonHoistthesafeoperationofequipment.Multi-ropefrictionhoistwithsmallsize,lightweight,safe,reliable,andstrongabilitytoupgradeapplytothedeeperminehoist.Inthispaper,thebrakingsystemforfour-ropefrictionroundhoisthavebeendesigned.Inthehoistbrakeselectionprocess,becauseinrecentyearsdiscbrakeisusedinthenewbrakesIt'suniquestrengthsandgoodsafetyperformancerecognizedbythemajorityofusers.EspeciallyinthelightofthehydrauliccontrolsystemandthePLC,HydraulicSystemandPLCsuperperformanceofthediscbrakeprovidesatremendousplatformforthework.BrakediscbrakingforceandrelyonthefueltankfilledwithoilthatdrivesthepistontocompressspringtoachieveDisc.Hydraulicdiscbrakesasthelatestdevelopmentofabrake,whichhasmanyadvantages.Thereforeitinamodernaircrafttypestoupgradegainwiderapplication.Itisthebrakingforce,flexibilitystability,highsensitivity;onproductionsafetyisofgreatsignificance.Keywords: Hoist; Multi­rope friction; Brake; Design; Hydraulic drive.目录摘要.............................................................................................................1 Abstract........................................................................................................2 前言.............................................................................................................7 第一章提升机的概述................................................................................9 1.1提升机的简介................................................................................9 1.2提升机的用途和发展概况...........................................................10 1.3提升机的工作原理.......................................................................13 第二章提升机的组成.............................................................................15 2.1 工作机构.....................................................................................15 2.2 制动系统.....................................................................................17 2.3 机械传动系统..............................................................................17 2.4润滑系统......................................................................................18 2.5观察和操纵系统...........................................................................18 2.6拖动，控制和自动保护系统.......................................................19 2.7辅助部分......................................................................................20 第三章提升机的选型计算.......................................................................21 3．1设计依据...................................................................................21 3.2提升容器选择..............................................................................21 3.3钢丝绳及提升机选择...................................................................223.4．提升机的选择............................................................................24 3.5．电机的选择...............................................................................25 3.6．提升机的校核............................................................................25 3.7 提升系统计算............................................................................26 第四章提升机卷筒的设计.....................................................................29 4.1卷筒的分类..................................................................................29 4.2 卷筒绳槽的确定..........................................................................29 4.3卷筒的确定..................................................................................30 4.4 卷筒强度计算..............................................................................32 第五章卷筒主轴的设计.........................................................................34 5.1 卷筒轴的受力分析与工作应力分析...........................................34 5.2 轴的设计计算............................................................................35 5.3.确定各段轴的直径和长度...........................................................36 5.4轴的校核......................................................................................36 第六章提升机的制动系统.....................................................................38 6.1 盘式制动器.................................................................................38 6.2盘式制动器的设计计算 ............................................................41 6.3 盘式制动器的调整和维护..........................................................49 第七章提升机的液压站.........................................................................51 7.1 液压站的功用........................
