The invention discloses an auxiliary limiting device for a rotary lazy arm. The auxiliary limiting device comprises a stand column, the transverse lazy arm is arranged at the upper end of the stand column, the left end of the lazy arm is rotationally connected with the stand column, a driving mechanism for driving the lazy arm to rotate is arranged on the portion, close to the left end, of the upper surface of the lazy arm, a hoisting mechanism capable of walking left and right is arranged on the lazy arm, the hoisting mechanism comprises a support walking on the lazy arm, an electric hoist isfixedly arranged at the lower end of the support, a vertical plate extending downwards vertically is arranged at the lower right end of the support, a limiting plate extending towards the left side is arranged at the lower end of the vertical plate, and the right end of the limiting plate is rotationally connected with the vertical plate. Limiting to a lifting hook during ascending is achieved through the limiting plate, when the lifting hook ascends to the position of the limiting plate, the limiting plate is driven to rotate upwards, the right end of the limiting plate rotates downwards todrive a touch support to move downwards to touch a limiting switch, and the limiting switch controls the electric hoist to be closed to prevent the lifting hook from ascending continuously to damage the electric hoist.

    本发明公开了一种旋转吊臂用辅助限位装置,包括立柱,立柱的上端设置有横向的吊臂,且吊臂的左端与立柱转动连接,吊臂的上表面靠近左端设置有驱动吊臂转动的驱动机构,吊臂上设置有可左右行走移动的起吊机构,起吊机构在吊臂上行走的支架,支架的下端固定设置有电葫芦,且支架的右下端设置有竖直向下的竖板,竖板的下端设置有向左侧延伸限位板,且限位板的右端与竖板转动连接,通过设置的限位板实现对吊钩上升时的限位,在吊钩上升到限位板位置时带动限位板向上转动,此时限位板的右端向下转动从而带动触碰支架向下移动触碰到限位开关,限位开关则控制电葫芦关闭防止吊钩继续上升造成电葫芦损坏。
