The invention relates to the field of cranes, in particular to a bridge crane beam structure which comprises a main beam structure, an end beam structure, a lubricating structure, a limiting structure and a supporting structure. The main beam structure is fixedly connected with the middle part of the end beam structure through the limiting structure; the two ends of the end beam structure are each provided with a lubricating structure and a supporting structure. The lubricating structure comprises a mounting frame, and the mounting frame is fixedly connected with the inner wall of an end beam body in the end beam structure. When a crane lifts a heavy object, the acting force of the main beam structure on the end beam structure is increased, the main beam structure and the end beam structure can move downwards by a certain distance by using the supporting structure when the crane lifts the heavy object, the supporting structure makes contact with a rail, the stability of the end beam structure in the moving process is improved, and damage caused by too large stress on the rail is avoided; by using the lubricating structure, when the crane lifts a heavy object, the driving wheel and the driven wheel in the end beam structure and the first supporting roller and the second supporting roller in the supporting structure can be lubricated.

    本发明涉及起重机领域,具体的说是一种桥式起重机梁结构,包括主梁结构、端梁结构、润滑结构、限位结构和支撑结构;所述主梁结构通过限位结构与端梁结构的中部固定连接;所述端梁结构的两端均设置有润滑结构和支撑结构;所述润滑结构包括安装架,所述安装架与端梁结构中端梁本体的内壁固定连接;在起重机吊起重物,主梁结构对端梁结构的作用力增大,支撑结构的使用使得主梁结构和端梁结构在起重机吊起重物时能够向下移动一端距离,支撑结构与轨道接触,提高了端梁结构移动时的稳定性,避免轨道受力过大造成损伤,润滑结构的使用,在起重机吊起重物时能够对端梁结构中的主动轮、从动轮和支撑结构中的第一支撑滚轮和第二支撑滚轮进行润滑。
