The invention discloses a liftable transverse beam for a bridge crane and an operation method. The liftable transverse beam comprises two bottom plates, wherein supporting mechanisms are arranged on the outer walls of the tops of the two bottom plates. Each supporting mechanism comprises two supporting plates, wherein the two supporting plates of each supporting mechanism are welded to the outer walls of the two ends of the top of the corresponding bottom plate, a transverse plate is arranged above each bottom plate, the two ends of each transverse plate are welded to the outer walls of the tops of the two corresponding supporting plates, and lifting mechanisms are arranged on the outer walls of the tops of the two transverse plates correspondingly. Each lifting mechanism comprises a supporting frame, wherein the bottom of each supporting frame is welded to the outer wall of the top of the corresponding transverse plate, a sliding plate is installed in each supporting frame in a sliding mode, a supporting column is welded to the outer wall of the top of each sliding plate, and a limiting frame is welded to the inner wall of the top end of each supporting frame. According to the liftable transverse beam for the bridge crane and the operation method, the stability is improved, the overall supporting strength of a device is improved, the height of a guide rail can be adjusted, the bridge crane can be suitable for hoisting occasions with different heights, the flexibility is improved, fixing blocks and the guide rail can be supported, the guide rail is prevented from being inclined, and the safety is improved.

    本发明公开了一种桥式起重机用可升降横梁及操作方法,包括两个底板,两个所述底板顶部外壁上均设有支撑机构,所述支撑机构包括两个支撑板,两个所述支撑板分别焊接于底板顶部两端外壁上,所述底板上方设有横板,且横板两端分别焊接于两个支撑板顶部外壁上,两个所述横板顶部外壁上均设有升降机构,所述升降机构包括支撑框,所述支撑框底部焊接于横板顶部外壁上,支撑框内滑动安装有滑板,所述滑板顶部外壁上焊接有支撑柱,所述支撑框顶端内壁上焊接有限位框。本发明提高了稳定性,提高了装置的整体的支撑强度,能够调节导轨的高度,能够适用于不同高度起重场合,提高了灵活性,能够对固定块和导轨进行支撑,防止导轨倾斜,提高了安全性。
