The invention discloses a quay crane gap bridge mechanism, which relates to the technical field of hoisting machinery, and comprises a rear girder and a front girder, the rear girder is provided with a sea side upper cross beam I, the land side surface of the sea side upper cross beam I is provided with a winch and a sea side trapezoidal frame, and the land side surface of the top cross beam of the sea side trapezoidal frame is provided with a pulley block II; when the head of the front girder and the seaside trapezoidal frame are located at the same horizontal position, the quay crane reaches a bridge crossing state, and after bridge crossing or the loading and unloading ship arrives at a target port wharf, a steel wire rope is reversely released through a winch to place the seaside trapezoidal frame and the front girder in place; after the whole quay crane upper structure is placed in place, the winch and the whole winding system are disassembled, the bridge crossing process is completed, the height limiting problem of small quay crane bridge crossing is mainly solved, the influence on the quay crane crossing cycle is small, bridge crossing tools are easy to arrange, a tool supporting rod does not need to be arranged independently, and cost is greatly reduced.

    本发明公开了一种岸桥过桥机构,涉及起重机械技术领域,包括后大梁和前大梁,所述后大梁上设置有海侧上横梁一,所述海侧上横梁一陆侧面布置有卷扬机和海侧梯形架,在海侧梯形架顶部横梁陆侧面布置有滑轮组二,前大梁绕着后大梁铰点逐渐扬起,当前大梁头部和海侧梯形架处于同一水平位置时,岸桥达到过桥状态,待过桥后或装卸船抵达目的港码头后再通过卷扬机反向放钢丝绳将海侧梯形架及前大梁放置到位,整个岸桥上部结构放到位后拆除卷扬机和整个缠绕系统,完成过桥工序,该机构主要解决小型岸桥过桥的限高问题,对岸桥交机周期影响小,过桥工装布置简单,无需单独设置工装撑杆,成本大幅降低。
