Abstract

本实用新型涉及一种液压支柱,尤其是一种柱塞悬浮式矿用单体液压支柱。包括:顶盖、上封堵、手把体、三用阀、活柱筒、油缸、底座,该油缸内套装有活柱筒,其顶端设置有顶盖,其下端设置有底座,其中部套装有手把体,所述底座通过圆柱销与油缸固接,该油缸底端焊接有堵板,该堵板上设置有安装孔,该安装孔内安装有下封堵,该下封堵的挂环上固接有复位弹簧。本实用新型的有益效果是该液压支柱代替了原有的套管式底座,使底座从整个支撑过程中脱离出来,保证在偏载受力过程中不会变形,从而防止泄露。

Description

柱塞悬浮式矿用单体液压支柱
技术领域
    本实用新型涉及一种液压支柱,尤其是一种柱塞悬浮式矿用单体液压支柱。
背景技术
目前,现有单体液压支柱的底座均采用油缸孔与底座轴配合密封或油缸外(轴)与底座孔配合密封,但在液压支柱在使用过程中,支柱轴向中心与底板很难达到绝对垂直,从而在每一次支撑过程就是一偏载受力过程,并且每一次支撑底座受力点不断变化导致底座与油缸配合面不断磨损造成间隙逐渐增大直至密封失效造成泄漏,进而导致矿山顶板事故频繁发生。
发明内容
    本实用新型要解决的技术问题是:提供一种结构新颖,密封性好,防偏载的柱塞悬浮式矿用单体液压支柱。
解决其技术问题采用的技术方案是一种柱塞悬浮式矿用单体液压支柱,包括:顶盖、上封堵、手把体、三用阀、活柱筒、油缸、底座,该油缸内套装有活柱筒,其顶端设置有顶盖,其下端设置有底座,其中部套装有手把体,所述底座通过圆柱销与油缸固接,该油缸底端焊接有堵板,该堵板上设置有安装孔,该安装孔内安装有下封堵,该下封堵的挂环上固接有复位弹簧。
本实用新型的有益效果是该液压支柱代替了原有的套管式底座,使底座从整个支撑过程中脱离出来,保证在偏载受力过程中不会变形,从而防止泄露。
附图说明
    图1为本实用新型结构示意图。
    图2为本实用新型A-A断面示意图。
图中:底座1,下封堵2,堵板3,O型密封圈4,挡圈5,油缸6,挂环7,复位弹簧8,活柱筒9,三用阀10,三用阀座11,手把体12,上封堵13,顶盖14。
具体实施方式
    以下结合附图及实施例对本实用新型进一步说明:一种柱塞悬浮式矿用单体液压支柱,包括:顶盖14、上封堵13、手把体12、三用阀10、活柱筒9、油缸6、底座1,该油缸6内套装有活柱筒9,其顶端设置有顶盖14,其下端设置有底座1,其中部套装有手把体12,所述底座1通过圆柱销与油缸6固接,该油缸6底端焊接有堵板3,该堵板3上设置有安装孔,该安装孔内安装有下封堵2,该下封堵2的挂环7上固接有复位弹簧8。
作为本实用新型的一种优选方案,所述堵板3与下封堵2之间嵌装有O型密封圈4和挡圈5。
当通过三用阀注入工作介质时,支柱内腔液体逐渐膨胀活柱筒9随之逐渐上升直至与顶板接触,支柱需移动时打开三用阀10的泄压阀支柱泄压,活柱复位原初始状。
