The invention discloses a large-span bridge crane, and relates to the technical field of bridge cranes, the large-span bridge crane comprises a sliding plate, one end of the top surface of the sliding plate is slidably clamped with a maintenance platform, one end in the maintenance platform is fixedly connected with a cross beam, one side of the cross beam is fixedly connected with a first rack, and the outer side of the first rack is engaged with a first gear. The horizontal position of the lifting box is adjusted through the cooperation effect of the first driving assembly and the first rack, when the lifting box breaks down, only the first driving assembly fixedly connected with the fault lifting box needs to be driven to move into the maintenance table, and the fault lifting box is maintained; at the moment, other lifting boxes on the cross beam can still work normally, and a worker adjusts the fixed position of the lifting hook, so that the large-span bridge crane can still carry goods, the maintenance cost of the large-span bridge crane is reduced, and the maintenance efficiency is improved. And meanwhile, the situation that the large-span bridge crane cannot work due to the fact that part of the sub-lifting mechanisms break down is avoided.
本发明公开了一种大跨度桥式起重机,涉及桥式起重机技术领域,包括滑动板,所述滑动板顶面的一端滑动卡接有维修台,所述维修台内部的一端固定连接有横梁,所述横梁的一侧固定连接有一号齿条,所述一号齿条的外侧啮合有一号齿轮。本发明,通过一号驱动组件与一号齿条的配合作用来调节升降箱的水平位置,当升降箱出现故障时,仅需将驱动固定连接有故障升降箱的一号驱动组件运动到维修台的内部,对故障的升降箱进行维修,而此时横梁上的其他升降箱仍可正常工作,工人调节吊钩的固定位置,使得该大跨度桥式起重机仍可搬运货物,降低了维修该大跨度桥式起重机的维修成本,同时避免出现部分子升降机构出现故障导致该大跨度桥式起重机无法工作的情况。
