The invention discloses a double-beam grab bridge crane, which belongs to the technical field of cranes, and comprises two end beams, main beams are arranged on two sides between the two end beams, a trolley is arranged at the upper end between the two main beams, a hook is arranged on the lower side of the trolley, and the hook is connected with the trolley through a lifting device. Through the arrangement of the buffer protection assemblies, when the trolley moves to the end of the main beam, the trolley makes contact with a buffer plate, the buffer plate pushes a sliding base to slide on a fixing rod through a rotating rod, the rotating rod rotates between the sliding base and the buffer plate, the sliding base moves to compress a spring, and the trolley moves to the end of the main beam; and meanwhile, the damping rods contract, the buffer plates can be buffered through the springs and the damping rods, and therefore the buffering effect on the trolley is achieved, the trolley and the end beam can be protected by arranging the buffer protection assembly, and the situation that the trolley moves to the end of the main beam and collides with the end beam, and consequently the trolley and the end beam are damaged is avoided.
本发明公开了一种双梁抓斗桥式起重机,属于起重机技术领域,包括两个端梁,两个所述端梁之间两侧设置有主梁,两个主梁之间上端设置有小车,小车下侧设置有挂钩,挂钩与小车之间通过起升装置连接,两个端梁一端与小车对应的位置设置有缓冲防护组件,本发明通过设置缓冲防护组件,当小车移动到主梁尽头时,小车接触到缓冲板,缓冲板通过转杆推动滑座在固定杆上滑动,转杆在滑座与缓冲板之间转动,滑座移动压缩弹簧,同时阻尼杆收缩,利用弹簧和阻尼杆可对缓冲板起到缓冲,从而达到对小车进行缓冲效果,通过设置缓冲防护组件可对小车和端梁起到防护作用,避免小车移动到主梁尽头与端梁发生碰撞造成小车和端梁损坏。
