Abstract

本实用新型提供了一种棘轮止逆滑轮装置。该装置的棘轮用螺钉固定在滑轮上，棘轮和滑轮的中心装有滑轮轴，活动盖板和侧板通过滑轮轴与滑轮和棘轮相连接，侧板上装有棘爪，棘爪与棘轮的外圆周相接触，侧板的上部用穿心螺栓与吊环板相连接。该装置由于棘爪将棘轮卡住不能倒转，且吊绳靠摩擦力与滑轮相对静止，因此牵引人员只需使用较小的力，就能使上吊重物稳定的悬停不致下落或抖动，同时降低了工作人员的劳动强度。

Description

棘轮止逆滑轮装置
技术领域
本实用新型涉及到机械领域，特别涉及到一种棘轮止逆滑轮装置。
背景技术
目前高处作业需要吊起100kg左右重物时，一般采用定滑轮、纤维绳由下方人员牵拽将重物提升。特别在起吊过程中需要停止或到达指定位置时，人力牵引力不能停，此时人力牵引不稳定、上下抖动不稳定，而且工作人员持续受力劳动强度较大。
发明内容
本实用新型的目的在于提供一种利用棘轮单向止逆的作用，使起吊重物只能单向上升不能下落的棘轮止逆滑轮装置。
为实现上述目的，本实用新型的技术方案为：
一种棘轮止逆滑轮装置，包括吊环板、活动盖板、滑轮轴、滑轮、棘轮、棘爪和侧板，该装置的棘轮用螺钉固定在滑轮上，棘轮和滑轮的中心装有滑轮轴，活动盖板和侧板通过滑轮轴与滑轮和棘轮相连接，侧板上装有棘爪，棘爪与棘轮的外圆周相接触，侧板的上部用穿心螺栓与吊环板相连接。
本实用新型的积极效果为：该装置由于棘爪将棘轮卡住不能倒转，且吊绳靠摩擦力与滑轮相对静止，因此牵引人员只需使用较小的力，就能使上吊重物稳定的悬停不致下落或抖动，同时降低了工作人员的劳动强度。
附图说明
图1、棘轮止逆滑轮装置主视图；
图2、棘轮止逆滑轮装置侧视图。
具体实施方式
下面结合附图1和2进一步说明本实用新型的具体实施方式。
参见图1、图2，将由穿心螺栓2相连接的吊环板1固定，使整个装置固定在指定的位置，打开活动盖板3，将吊绳通过活动盖板3穿入滑轮5内，在滑轮5上吊绳至少绕一圈以上，吊绳的一端吊上重物，另一端由操作人员牵引。
当操作人员向下拉吊绳时，吊绳会带动滑轮5绕滑轮轴4转动，同时用螺钉7固定在滑轮5上的棘轮6也一同转动，重物会被吊起。当中途停止或重物到达指定位置时，滑轮5和棘轮6同时停止转动，此时装在侧板9上的棘爪8将棘轮6卡住，使滑轮5和棘轮6不能倒转，同时吊绳靠摩擦力使滑轮5相对静止，此时操作人员只需使用较小的力，就能使上吊的重物悬停不致下落或抖动。
