The invention belongs to the technical field of overload limiters, and discloses an overload limiter structure of a bridge crane, which comprises an over-limit device body, a connecting disc is mounted in the center of the top of the over-limit device body, and hoisting cables are arranged on two sides of the over-limit device body in a penetrating manner. The movable cavities, the alarm cavities and the adjusting cavities are formed in the overrun device body, the two movable cavities, the two alarm cavities and the two adjusting cavities are symmetrically arranged in the overrun device body, and the movable assemblies are arranged in the movable cavities in a sliding mode and used for being connected with a hoisting cable. The alarm assembly is arranged in the alarm cavity in a sliding mode and used for triggering overload alarm, and the adjusting assembly is arranged in the adjusting cavity and used for adjusting stress of the two ends of the overrun device body during hoisting. The overload limiter solves the problems that when an existing bridge crane hoists heavy objects storing liquid inside a storage tank or an oil drum, the heavy objects are moved, so that the weight distribution at the two ends of internal liquid flowing is not uniform, and normal work of the overload limiter is affected.

    本发明属于超载限制器技术领域,且公开了一种桥式起重机的超载限制器结构,包括超限器本体,所述超限器本体顶部中心位置安装有连接盘,所述超限器本体的两侧均穿设有吊装索,还包括:分别开设于超限器本体内部的活动腔、报警腔以及调节腔,且所述活动腔、报警腔以及调节腔均设有两个,并在超限器本体内部互相对称设置,滑动设置于活动腔内用于与吊装索相连的活动组件,以及滑动设置于报警腔内用于触发超载报警的警报组件,设置于调节腔内用于调节吊装时超限器本体两端受力的调节组件。本发明解决了目前桥式起重机在吊装储罐或油桶等内部存储液体的重物时,因移动重物,导致内部液体流动两端重量分布不均,影响超载限制器正常工作的问题。
