Description

气动液压千斤顶
技术领域
本发明涉及液压千斤顶,尤其涉及自动液压千斤顶。
背景技术
目前,一般液压千斤顶都是人工压动摇杆使其顶起重物,只能手动操作,劳动强度较大。
发明内容
本发明的目的是为了提供气动液压千斤顶,可以自动顶起重物,同时使用压缩空气,系统简单,只需按动按钮阀就可自动顶起重物。
    本发明的技术方案是:
1.气动液压千斤顶,包括摇杆和小活塞,其特征在于:还包括气缸、气管、机动换向阀、按钮阀和以及用于固定气缸的固定支座;所述气缸包括缸体、弹簧、活塞和活塞杆,所述活塞位于活塞杆的端部,所述弹簧套于活塞杆上,所述活塞和活塞杆位于缸体内,所述活塞可在缸体的内腔中相对于缸体做往复运动,且所述弹簧的一端顶于活塞上,另一端则顶于缸体的缸盖,所述活塞杆与摇杆为铰链连接,所述摇杆顶住小活塞的活塞杆,所述所气管一端接于缸体的内腔中,另一端接至机动换向阀,所述机动换向阀通过气管与按钮阀连接,在所述机动换向阀上有压块,当摇杆到达水平位置时压动机动换向阀的压块。
有益效果
本发明由于采用气动装置,系统简单,操作方便,自动化程度高。
附图说明
图1为本发明气动液压千斤顶的结构示意图。
1、摇杆;2、小油缸;3、小活塞;4、第一单向阀;5、进油管;6、油管;7、第二单向阀;8、大活塞;9、大油缸;10回油管;11、截止阀;12、油箱;13、气缸;14、固定支座;15气管;16、机动换向阀;17、按钮阀。
具体实施方式
如图1所示,气动液压千斤顶,包括摇杆和小活塞,其特征在于:还包括气缸、气管、机动换向阀、按钮阀和以及用于固定气缸的固定支座;所述气缸包括缸体、弹簧、活塞和活塞杆,所述活塞位于活塞杆的端部,所述弹簧套于活塞杆上,所述活塞和活塞杆位于缸体内,所述活塞可在缸体的内腔中相对于缸体做往复运动,且所述弹簧的一端顶于活塞上,另一端则顶于缸体的缸盖,所述活塞杆与摇杆为铰链连接,所述摇杆顶住小活塞的活塞杆,所述所气管一端接于缸体的内腔中,另一端接至机动换向阀,所述机动换向阀通过气管与按钮阀连接,在所述机动换向阀上有压块,当摇杆到达水平位置时压动机动换向阀的压块,使机动换向阀换向。
所述气动液压千斤顶的工作过程如下:当按下按钮阀17时,压缩气体通过气管15、机动换向阀16进入气缸13的上部,压动气缸的活塞与活塞杆下行,通过铰链带动摇杆1下压小活塞3,小活塞3下移,小活塞3下腔压力升高,第一单向阀4关闭,第二单向阀7打开,下腔的油液经管道6输入大油缸9的下腔,迫使大活塞8向上移动,顶起重物;当摇杆到达水平位置时压动机动换向阀16的压块,使机动换向阀16换向,此时气缸13不进气而放气,活塞与活塞杆在弹簧的作用下上行,同时使摇杆1带动活塞杆使小活塞3向上移动,小活塞3下端油腔容积增大,形成局部真空,这时第一单向阀4打开,通过吸油管5从油箱12中吸油,通过气缸不断地往复带动摇杆,就能不断地把油液压入大油缸9下腔,使重物逐渐地升起。当重物升至合适的位置时,松开按钮阀的按钮,气缸不进气,摇杆不移动,在两单向阀的作用下,使重物停留在指定的位置。如果打开截止阀11,大油缸9下腔的油液通过管道10、截止阀11流回油箱,重物就向下移动。
