The invention discloses a safe and anti-collision bridge crane. The safe and anti-collision bridge crane comprises a load-bearing cross beam, a mounting shell is fixedly connected to one end of the top of the load-bearing cross beam, a movable rod is movably connected to one end of the mounting shell, the movable rod movably penetrates through and extends into the mounting shell, and a stop block is fixedly connected to the end, away from the mounting shell, of the movable rod. According to the safe and anti-collision bridge crane, a running trolley is matched with a first air bag to drive the stop block and the movable rod to move towards one end of the mounting shell, so that a first movable plate extrudes air in a corrugated pipe and drives a piston to move to the position of a second communicating hole; and at the moment, air in the corrugated pipe rushes into the first air bag and a second air bag through the second communicating hole, the movable pipe and a first communicating hole, the first air bag and the second air bag are made to expand instantly to generate force resisting the running trolley, the impact force of the running trolley is weakened, and therefore the purpose of preventing the running trolley from being collided and damaged is achieved.
本发明公开了一种可安全防撞的桥架式起重机,包括承重横梁,所述承重横梁顶部的一端固定连接有安装壳,所述安装壳的一端活动连接有活动杆,且活动杆活动贯穿并延伸至安装壳的内部,所述活动杆远离安装壳位置的一端固定连接有阻挡块。本发明通过运行小车配合第一气囊带动阻挡块和活动杆向安装壳一端位置移动,会使得第一活动板挤压波纹管内部的空气,并带动活塞移动至第二连通孔位置时,此时波纹管内部的空气通过第二连通孔、活动管和第一连通孔冲向第一气囊和第二气囊的内部,并使得第一气囊和第二气囊瞬间膨胀产生与运行小车相抵抗地力,并对运行小车的冲击力进行削弱,从而起到防止运行小车碰撞损坏的目的。
