Abstract
The utility model discloses a girder for an explosion-proof suspension crane which relates to a crane. The utility model aims to provide a girder for a flameproof suspended crane with large lifting tonnage. The utility model adopts the technical proposal that: the girder for the flameproof suspended crane is formed by two flange beams being connected in parallel and welded into a whole, and a cover plate is respectively welded on the upper surface and the lower surface of the two parallel flange beams. The utility model is applied to explosion-proof cranes.
Description
Technical field:
The utility model relates to the girder of a kind of hoisting crane, particularly a kind of explosion-proof overhang crane.
Background technology:
Along with the technical development overhang crane is used more and more widely, this hoisting crane is specially adapted to the maintenance of the coal mill of power plant, steel mill, because the scale of power plant, steel mill constantly enlarges in recent years, the mill weight of coal mill has reached 28 tons, the hoisting capacity of existing overhang crane has only 5 tons, can not meet requirements.The subject matter that restricts this hoisting crane tonnage is the structure of crane girder, and existing girder is welding one channel-section steel on a H-girder, and this structure bearing capacity is less.
Summary of the invention:
The purpose of this utility model provides the girder of the big explosion-proof overhang crane of a kind of lifting tonnage.The technical solution of the utility model is that a kind of girder of explosion-proof overhang crane is characterized in that: girder is that two I-beam section parallel connections are integrally welded, is welded with a cover plate respectively on the upper and lower surface of two I-beam sections of parallel connection.The utility model has the big advantage of lifting tonnage compared with the prior art.
Description of drawings:
Accompanying drawing is the end face structure scheme drawing of the utility model explosion-proof crane girder.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, in order to improve the tonnage of hoisting crane, the utility model adopts two I-beam sections 1 and connects integrally weldedly, and respectively welds a cover plate 2,3 on the upper and lower surface of two I-beam sections.
Claims (1)
1. the girder of an explosion-proof overhang crane, it is characterized in that: girder is that two I-beam section parallel connections are integrally welded, is welded with a cover plate respectively on the upper and lower surface of two I-beam sections of parallel connection.
