【说明书】千斤顶课程设计

【关键字】说明书千斤顶设计说明书院系班级学号设计人指导教师完成日期螺旋千斤顶设计过程千斤顶一般由底座1,螺杆4、螺母5、托杯10,手柄7等零件所组成(见图1―1)。
螺杆在固定螺母中旋转,并上下升降,把托杯上的重物举起或放落。
设计时某些零件的主要尺寸是通过理论计算确定的,其它结构尺寸则是根据经验公式或制造工艺决定的,必要时才进行强度验算。
设计的原始数据是:最大起重量F=20KN和最大提升高度H=.1.5结构(见图1―2)螺杆上端用于支承托杯10并在其中插装手柄7,因此需要加大直径。
手柄孔径d k的大小根据手柄直径d p决定,d k≥d p十0.5mm。
由后面的计算可知手柄的直径pd=25mm,所以mmdk8.268.026=+=。
为了便于切制螺纹,螺纹上端应设有退刀槽。
退刀槽的直径d4应比螺杆小径d1约小0.2~0.5mm。
mmdd6.204.014=-=。
退刀槽的宽度可取为1.5P=15mm。
为了便于螺杆旋入螺母,螺杆下端应有倒角或制成稍小于d1的圆柱体。
为了防止工作时螺杆从螺母中脱出,在螺杆下端必须安置钢制挡圈(GB/T891-1986)mmHmmD5,45==,挡圈用紧定螺钉(GB/T68-2000)166⨯M固定在螺杆端部。
1.5P=15mm计算项目计算及说明计算结果(1)螺母与底座的配合常用或等;(2)为防止螺母转动,应设紧定螺钉,直径常取M6~M12,根据起重大小决定;(3)为防止托杯脱落和螺杆旋出螺母,在螺杆上下两端安装安全挡圈;(4)连接螺钉,挡圈,挡环的规格尺寸按结构需要选取或设计;(5)为减少摩揩、磨损及托杯工作时不转动,螺旋副及托杯与螺杆的接触面均需润滑;(6)装配图尺寸标注应包括特性尺寸(如最大起落高度)、安装尺寸、外形尺寸(总厂、总宽、总高)和派和尺寸等;(7)图面应注明技术特性及技术要求;(8)图纸规格应符合之徒规定,绘图要按国家标准,标题栏和明细表的格式应符合要求,详见课程设计教材,或采用学生用标题栏及明细表格式;(9)设计计算说明书应在全部计算及图纸完成后进行整理编写。
YN4000千斤顶说明书

YDC4000N-100千斤顶使用说明书四平市欧维姆机械有限公司一、用途YDC4000N-100型千斤顶是一种内卡式张拉群锚的穿心式千斤顶,可配19孔及19孔以下的锚具进行张拉,广泛适用于先张、后张拉法的预应力混凝土结构、构件、桥梁、水工结构、核电站安全壳、岩石锚固、坝基锚固等工程。
二、型号及技术参数型号:YDC4000N-100公称张拉力:4000KN张拉面积:7.693X10-2m2额定油压:52MPa张拉行程:100mm三、构造及工作原理该千斤顶的缸体与缸盖采用螺纹连接,动密封采用格莱圈密封,固定密封采用两道O形密封圈,千斤顶内有前置锚具、限位板、导向杆、弹簧、挡板等,张拉不同孔数锚具时,更换相应孔数的内卡装置即可。
使用前,工具锚锚环锥孔全部涂石蜡。
在张拉过程中,重复使用一段时间后应对工具锚夹片进行检查,如发现有损伤,应及时更换夹片。
图1千斤顶结构示意图四、使用方法1、安装好工作锚具后,千斤顶回程到底升压至5MPa后,再穿入钢绞线,用磨好端头的钢绞线试插千斤顶里的夹片,使之完全归位。
安装好即可开始张拉。
2、按图1所示,将B路截止阀和节流阀打开,使B路处于回油状态,关闭A路使之处于进油状态,调整A路节流阀控制A路油速度和升压,张拉开始。
3、在活塞外伸时,工具锚夹具可自行夹紧钢绞线,工作锚中的夹片此时因受限位套的支托,退出不会太多。
4、当张拉完毕即可停止向A路供油,打开A路节流阀,同时转回截止阀,A路压力至零点,由于钢绞线束的回缩,活塞回程到若干毫米,工作锚的夹片被连动带入锚板内部自行夹紧。
5、B路关闭截止阀调整节流阀,控制流量和升压,活塞回程到底,起压小于20MPa停泵,此时完成一次张拉循环。
五、注意事项使用本千斤顶时,除应遵守一般预应力施工操作的有关规范外,还应注意以下问题。
1、千斤顶应采用优质矿物油,油内不含水及其它混合物,在通常温度下不分解、不变质,油液应严格保持清洁,经常过滤、定期更换,建议冬季用YC-N15号液压油,夏季用YB-N32号液压油。

起重量为6.6t(约66000N),起重高度为180mm,间歇工作,可用于比较狭窄的工作场合。
1.2设计要求螺旋千斤顶是用人力转动手柄来举升重物的机械,它应有以下几个要求:a.能满足将5.5t重物举起180mm的功能,并能平稳的下降且具有足够的使用寿命。
b.在上升及下降过程中,可以停在任意位置而不自行下滑。
c.人手推力不可以过大,防止人产生过度疲劳。
d.千斤顶的支承面与重物之间不能有相对滑动,千斤顶与地面有足够的接触面积。
e.除以上要求外,还应保证工作可靠,操作安全,加工经济等。
1.3主要零件的常用材料螺杆:45螺母:ZQSn10-1底座:HT150托杯:Q235手柄:A31.4千斤顶结构示意图第二章 主要零件受力分析图1和图2分别表示螺杆和螺母的受力情况。
螺杆除受压力Q 外,还受转矩,即螺母的摩擦力矩T 1和推力轴承的摩擦力矩T 2。
其中T 2由以下公式求得F d T 22μ= (1) 其中:μ——滚动轴承的摩擦系数,对单向推力轴承μ=0.0013~0.0020d ——轴承内径,mmF ——轴承负荷,对推力轴承是轴向负荷,NT 1和压力Q第三章 螺杆的设计计算3.1螺杆牙型选择考虑到螺旋千斤顶要求在上升及下降过程中,可以停在任意位置而不自行下滑(即有自锁能力),又要使结构简单,故采用滑动螺旋,并选用梯形螺纹,牙型角α=30°,梯形螺纹内外螺纹以锥面相结合,不易松动,牙形可按照GB5796.1—86的规定。

千斤顶是由底座、螺套、绞杠、螺旋杆、顶垫和两枚规格不同的螺钉装配而成。装配的过程从底座开始,螺套嵌压底座中,一边用螺钉固定以防止螺套和底座之间的相对运动。螺旋杆的球面形顶部套上一个顶垫,用螺钉连接,以防止顶垫脱落或随螺旋杆一起旋转。
五、千斤顶的工作原理
千斤顶是简单起重工具,在工作时,用可调节力臂长度的绞杠带动螺旋杆在螺套中作旋转运动,螺旋作用螺栓杆上升,装在螺栓杆头部的顶垫顶起重物。骑缝安装的螺钉M10阻止螺套回转,顶垫与螺旋杆头部以球面接触,其内径与螺栓杆有较大间隙,即可减小摩擦力不使顶垫随同螺栓杆回转,又可自调心使顶垫上平面与重物贴平;螺钉M8可防止顶垫脱出。
