Description

液压切断器
技术领域
本实用新型涉及一种液压切断工具,尤其是一种可实现对钢绞线、钢索、钢筋等切断的液压切断器。
背景技术
目前,在液压切断领域所采用的切断器多为结构复杂,零件较多,尤其是对钢绞线、钢索、钢筋进行切断的装备,其重量较大,搬运使用极为不方便,因此,其使用受到局限,且制造成本较高,制造工序较为复杂,不便于维修,不能得到很好的推广使用。目前,对该类简单切断器的研究也有相关记载,但其效果没有大的改进,因此,随着人类社会的进步及该领域的强烈需求,对液压切断器进行结构简单化、功能齐全化、成本较低化的研究越来越引起人们的关注。
实用新型内容
为解决现有技术中存在的不足,本实用新型提供了一种机构简单、使用方便、方便维修的液压切断器。
本实用新型要解决上述的技术问题是通过以下的技术方案实现的:
本实用新型的液压切断器包括带有进油口的油缸,在油缸的内部设置有带有回位弹簧的活塞,弹簧安装在衬套和油缸之间,所述的活塞通过装配在油缸内部的衬套定位在油缸的内部,并在衬套与进油口之间的油缸本体上形成液压腔;在液压腔的左部设有固定安装在油缸上的定刀架,动刀设置在定刀架内部且尾部与活塞的自由端固连,动刀与定刀架内壁滑动配合;在定刀架的左部上方设有安全管,所述的安全管与定刀架内腔相连通;在定刀架左部下方、与安全管对应位置上设有耐磨套,所述的耐磨套与定刀架内腔相连通。
作为本实用新型方案的更进一步改进,所述的安全管轴线与耐磨套的轴线重合。
由于采用了上述技术方案,本实用新型取得的进步在于:
采用上述技术方案,钢筋或钢索经耐磨套、安全管穿过切断器,液压油经进油口进入液压腔,驱动活塞,活塞带动动刀沿定刀架轨道一同前进,同时把弹簧压缩,动刀把钢筋或钢索顶紧后,停止前进,油缸内的压力持续升高,直至把钢筋或钢索切断,停止给切断器供油,并泄压,回位弹簧的弹力作用在活塞上,实现活塞及动刀的复位,同时把液压油经油管送回油箱,把切断的钢筋或钢索取走,完成一次工作过程。因此,其结构简单,使用方便,制造成本低。
附图说明
图1是本实用新型的整体结构示意图。
其中,1、进油口,2、油缸,3、活塞,4、回位弹簧,5、衬套,6、定刀架,7、耐磨套,8、动刀,9、安全管,10、液压腔。
具体实施方式
下面将结合说明书附图对本实用新型做进一步说明。
该液压切断器包括带有进油口1的油缸2,在油缸2的内部设置有带有回位弹簧4的活塞3,回位弹簧4位于衬套5和油缸2之间,所述的活塞3通过装配在油缸2内部的衬套5定位在油缸2的内部,并在衬套5与进油口1之间的油缸2本体上形成液压腔10,在液压腔10的左部设有固定安装在油缸2上的定刀架6,动刀8设置在定刀架6内部且尾部与活塞3的自由端固连,动刀8与定刀架6内壁滑动配合;在定刀架6的左部上方设有安全管9,所述的安全管9与定刀架6内腔相连通;在定刀架6左部下方、与安全管9对应位置上设有耐磨套7,所述的耐磨套7与定刀架6内腔相连通。安全管9轴线与耐磨套7的轴线重合。
在装配时,活塞3上装回位弹簧4及衬套5,装入油缸2,定刀架6与油缸2连接,把动刀8固定在活塞3上,安全管9、耐磨套7分别固定在定刀架6上,完成组装。其使用方便,便于维修。
