Description

一种曳引机安全盘车保护装置
技术领域
本发明涉及一种曳引机紧急救援或检修时的盘车安全保护装置。 
背景技术
当电梯在运行过程中发生故障或者停电时，需要把被困人员救出轿厢，可通过盘车装置对曳引机进行手动盘车来实施救援，在实施救援前，要对曳引机的电源进行切断。目前应用比较广泛的一种曳引机盘车保护装置是在盘车支架6上安装一个带手动复位的盘车开关5，在实施救援时，盘车装置中的驱动齿轮10与小齿轮2完全啮合时（如图1），盘车手轮1才能完全接触到盘车开关5切断电源。以上的盘车装置虽然在功能上也能够实现盘车时的电源切断，但是由于齿轮具有一定的厚度，在两个齿轮开始啮合时，盘车开关未动作，如果此时曳引机电源仍未切断，存在很大的安全隐患。 
发明内容
本发明目的就是提供一种在盘车实施之前，能够彻底切断曳引机电源的盘车保护装置。 
本发明目的是这样实现的：包括带有盘车驱动齿轮的曳引机、带有盘车小齿轮的盘车手轮、带小齿轮定位孔的盘车支架、常开并带自复位弹簧电梯专用行程开关、开关固定板、盘车开关压板、调节螺钉、固定螺钉，盘车开关安装在盘车开关固定板上并固定在盘车支架上，盘车支架则固定在曳引机上，盘车开关压板通过螺钉固定在盘车开关固定板上。在非救援状态时，通过调节螺钉把盘车开关调节到闭合状态，此时曳引机处于通电状态，在此状态下，在盘车开关压板的阻挡下，无法实施盘车。在救援状态或检修时，通过松开螺钉取下盘车开关压板，盘车开关自复位到常开状态，实现盘车动作实施前即切断电源。 
    本实用新型与已有技术相比，具有在盘车实施之前，能够彻底切断曳引机电源的优点。 
附图说明
图1是已有技术的结构示意图。 
图2是本实用新型的结构图。 
图中序号说明：盘车手轮1、盘车小齿轮2、调节螺钉3、盘车开关固定板4、盘车开关5、盘车支架6、曳引机7、蝶形螺钉8、盘车开关压板9、驱动齿轮10。 
具体实施方式
下面结合附图对本实用新型作进一步描述： 
本实用新型是这样实现的，如图2所示，其结构包括盘车手轮1、盘车小齿轮2、调节螺钉3、盘车开关固定板4、盘车开关5、盘车支架6、曳引机7、蝶形的螺钉8、盘车开关压板9、驱动齿轮10，盘车开关5安装在盘车开关固定板4并固定在盘车支架6上，盘车支架6则固定在曳引机7上，盘车开关压板9通过两个蝶形的螺钉8固定在盘车开关固定板4上，通过调节螺钉3把盘车开关5调节到闭合状态。在非救援状态时，通过调节螺钉8把盘车开关5调节到闭合状态，此时曳引机7处于通电状态，在此状态下，无法实施盘车。在救援状态或检修时，通过松开蝶形螺钉8取下盘车开关压板9，盘车开关5自复位到常开状态，实现盘车动作实施前即切断电源，此时盘车小齿轮2与驱动齿轮10可以啮合并盘车。
