它具有结构紧凑、操作方便、工作安全可靠、维修简单、运转平稳、无 级变速等优点作为防爆牵引，提升动力装置，特别适用于船舶、油田、地质钻井、矿山开采及易爆、易 燃气体等场所图1 JQHS系列风动绞车（高底座）外形图The Series Of JQHS Pneumatic Winches Outline Drawing For High Seat正确安装使用和认真维护保养，是使气动绞车正常可靠的工作，延长其使用寿 命的重要保证用户应仔细阅读本说明书，以便正确的掌握风动绞车的安装、使用和保养方法，充分 发挥气动绞车的功能根据用户使用意见和科学技术的发展，本气动绞车也将不断进行改进提高，本 说明书所述某些内容，可能会有些改动，说明书不可能随时变动，敬请用户注意Chapter 1:Brief introductionAdopting pneumatic motor as power, Pneumatic winch model JQHS series can tow and lift heavy goods through speed-reducing gearbox to drive roll. It has the advantages of compact structure,, convenient operation, safety and reliable operating, simple maintenance, smoothly running and stepless speed - changing etc. It is suitablyused in oil field, well-drilling in oil field, mine-exploiting and other place with inflammable or easy exploding air.To ensure the pneumatic winch works normally, make best use of it and prolong its working life, it is very important for users to install, operate and maintain it correctly and carefully. It is advisable thatthe consumers should read the manual book carefully before using it. 第二章主要结构及工作原理一、主要结构 气动绞车的主要结构见图2。

本绞车的气动马达本身具有一定的自锁功能，当操纵手柄回复中位时，进、排 气腔均封闭如果此时绞车处于吊重状态，重物基本不下降，或有缓慢下滑为保证用户使用的绝对 安全，绞车还设计有制动系统 本系统的制动系统按数量可分为单刹、双刹，按类型可分为手刹、盘刹用户 可根据不同习惯和使用场合选用Chapter 2:Main structure and Principle of Work 1. Main structure(Fig 2)2. Principle of WorkWhen move handle lever(3) to staring position, the distributingvalve(2) opens and the compressed air entersdistributing valve filter(1) and makes it turn. With the turning of filter, the compressed air will be sent into the fivecylinders(6) in proper order. The air in cylinders will expand, it can drive piston (4),connecting rod(5) andcrankshaft(7) turn. When the piston(4) turn to “B.T.D” position, the filter(1) turns to the exhaust position at the3same time. The expanded air will discharge through exhaust hole directly, the other air in cylinder also dischargethrough the exhaust hole of filter(1) and distributing valve(2).Circulating like this, the crankshaft(7) turnscontinuously which drives reel(8) turn through transmission shaft and gears.The pneumatic motor has self-lock function. When the handle lever is in neutral position, All the inlets andoutlets close. At this time, if the winch is lifting goods, the goods will not fall or fall very slowly. In addition, toensure that users work safely, the winch also adopts brake system. according to the quantity of brake ,the systemis classified into single-brake, double-brake, according to brake types, it is classified into hand-brake, foot-brake,hydraulic-brake and pneumatic brake .第三章主要技术参数项目规格及参数型号 JQHS-20X24额定牵引力 20KN额定 绳速 24m/min额定 功率 17KW进气压力 0.5-0.7MPa耗气量 12.7m?/min容 绳 量 200m钢丝绳直径 14mm外形尺寸 1160X500X790mm重 量 420kgCHAPTER 3:MAIN TECHNICAL DATAItem SpecificationJQHS-20X24 ModelMax. lifting force 20KNMax. lifting speed 24m/minRated power 17KWAir intake pressure 0.5-0.7MPa12.7m?/min Rated air consumptionWire capacity 200mDiameter of wire 14mm1160X500X790mm Base connec ting dimensionNet weight 420kg第四章 吊运及安装一、吊运气动绞车吊运中。
