Description

带连接套的单体液压支柱
技术领域
本实用新型涉及一种主要用于煤矿井下采煤工作面顶板支护用的带连接套的单体液压支柱。
背景技术
在已有技术中，单体液压支柱它由底座、套在底座内的加长段、套在加长段上外端且横穿插有三用阀的连接套、套在连接套上内端的油缸、套在油缸上外端且穿插有活柱的手把体和套在活柱外上端的柱帽构成，连接套采用卡腰套，即缩径结构，其缺点是连接套卡腰处强度底，受力不均，易折损；连接套与油缸、加长段采用焊接，维修不方便、效率低。
发明内容
本实用新型的目是针对上述不足而提供一种使用效果更好的带连接套的单体液压支柱。
本实用新型的目的是这样实现的：带连接套的单体液压支柱，它由底座、套在底座内的加长段、套在加长段上外端且横穿插有三用阀的连接套、套在连接套上内端的油缸、套在油缸上外端且穿插有活柱的手把体和套在活柱外上端的柱帽构成，连接套为直套。连接套与油缸、加长段采用穿钢丝和穿销钉连接。
本实用新型的优点是：连接套为直套，该处的连接结构强度不降低，不易折损，使用更加安全。连接套与油缸、加长段采用穿钢丝和穿销钉连接，维修维护方便、效率高。
下面将结合附图对本实用新型作进一步详细描述：
附图说明
附图是本实用新型结构简图。
具体实施方式
