Bridge crane beam structure and bridge crane
The crane beam needs to bear a lot of pressure. In order to meet the lifting needs, the structural design requirements of the crane beam are very high. In the prior art, the common practice is to use large-size crane beam when the lifting tonnage is large, and small-size crane beam when the lifting tonnage is small. Even in order to meet the national standards, excessive size is used to meet the lifting requirements and improve the safety factor. This is a rough design concept, resulting in a lot of waste of materials and energy. Especially when there is a large-span lifting demand, the large-scale crane beam will bring great difficulties to transportation and installation.
Therefore, it is necessary to design a scientific and reasonable crane beam structure, so that the crane beam can meet higher lifting requirements under the same size and weight.
Contents of the utility model:
In order to make the crane beam meet higher lifting requirements under the same size and weight, the utility model provides a crane beam structure.
The bridge crane beam structure provided by the utility model comprises: a rectangular box body, which is surrounded by a top plate, a bottom plate, two side plates and two sealing plates, the top plate is fixed above the two side plates, the bottom plate is fixed below the two side plates, the two sealing plates are fixed at both ends of the two side plates, and a number of stiffeners are evenly distributed horizontally and vertically on the inner wall of the two side plates; Two rollers fixed at both ends of the bottom plate.
By adopting the above technical scheme, the crane beam can meet higher requirements under the same size and weight
The lifting demand reduces the production cost, facilitates the transportation and installation, reduces the requirements for the crane beam support structure, and realizes the intensive, scientific and reasonable design of the crane beam structure, which has a wide application prospect.
The utility model also provides a bridge crane, which comprises a bridge crane described in any of the above technical schemes
Machine beam structure.
The bridge crane provided by the utility model also has the above beneficial effects.
