At present, all bridge cranes have a certain height. The upper and lower cover plates of the end beam structure are parallel horizontal rails. The structure is limited by the height of the plant structure. When the lifting equipment needs to be lifted, it cannot touch the roof of the factory. Therefore, the horizontal rails of the end beam of the crane need to be changed accordingly.
The utility model discloses an end beam structure of a bridge crane, which comprises an upper cover plate (1), a lower cover plate (2), a web plate (3), a bending plate (4), the web plate (3) is connected with the upper cover plate (1) and the lower cover plate (2) by welding, the upper cover plate (1) and the lower cover plate (2) are connected by a stop frame (5), and the bending plate is arranged at both ends of the lower cover plate. It is characterized in that the surface of the upper cover plate (1) is provided with a strip groove, that is, its section is a trapezoidal notch (6). Through the strip groove on the surface of the upper cover plate of the crane end beam, that is, the sinking structure of the trapezoidal notch, the whole height of the crane is reduced, which is not limited by the height of the plant structure. It can not only meet the lifting height of the equipment, but also meet the overall dimensions of the lifting equipment.
1. An end beam structure of bridge crane, comprising an upper cover plate (1), a lower cover plate (2), a web plate (3), a bending plate (4) and a web plate
(3) The utility model is connected with the upper cover plate (1) and the lower cover plate (2) by welding, the upper cover plate (1) and the lower cover plate (2) are connected by a stop frame (5), and the bending plates are arranged at both ends of the lower cover plate. It is characterized in that the surface of the upper cover plate (1) is provided with a strip groove, that is, its broken surface is a trapezoidal notch (6).
2. The end beam structure according to claim 1, which is characterized in that the strip groove, that is, the trapezoidal notch (6) on the section is arranged in the middle of the upper cover plate of the end beam.
