The invention discloses a limiting and locking device of a bridge crane, and relates to the technical field of cranes. Comprising a middle block, an adjusting mechanism is arranged at the top end of the middle block and comprises two connecting blocks, two inclined plates distributed in a V shape are fixed to the top end of the topmost connecting block, a top limiting and triggering mechanism is arranged on one side of the bottom end of the middle block, and a bottom limiting mechanism is arranged on the other side of the bottom end of the middle block; the bottom limiting mechanism comprises a disc-shaped block. The device is provided with the inclined plate, the adjusting mechanism, the top limiting and triggering mechanism, the buffer assembly, the locking mechanism and the bottom limiting mechanism, under the elastic action of the top limiting and triggering mechanism, the limiting ruler is limited between the bottom limiting mechanism and the top limiting and triggering mechanism, and the bottom limiting mechanism is limited through the locking mechanism, so that the limiting ruler is not prone to falling off. During working, under the condition that the steel wire shakes, external force which is upwards generated and acts on the limiting ruler can be buffered by a spring of the top limiting and triggering mechanism.

    本发明公开了一种桥式起重机限位锁定装置,涉及起重机技术领域。包括中部块,所述中部块的顶端设置有调节机构,调节机构包括两个连接块,最顶部的连接块的顶端固定有两个呈V型分布的斜板,中部块的底端一侧设置有顶部限位及触发机构,中部块底端的另一侧设置有底部限位机构,底部限位机构包括盘型块。本发明设置有斜板、调节机构、顶部限位和触发机构、缓冲组件、锁定机构和底部限位机构,在顶部限位和触发机构的弹力作用下,限位尺被限位在底部限位机构和顶部限位和触发机构之间,并且通过锁定机构对底部限位机构进行限位,这样,工作时,钢丝晃动的情况下,向上产生作用在限位尺上的外力可以被顶部限位和触发机构的弹簧进行缓冲。
