Abstract

The utility model discloses a truss type electric single-beam crane main beam which has a triangular truss structure. The truss type electric single-beam crane main beam is formed by an I beam, a bottom horizontal truss sheet, a middle vertical truss sheet and inclined web pipes on two sides which are welded with one another, wherein vertical web members and inclined web members of the bottom horizontal truss sheet are welded on web members of the I beam through node plates, and the outer ends of the vertical web members and the inclined web members of the bottom horizontal truss sheet are welded on a lower chord member; vertical web members and inclined web members of the middle vertical truss sheet are welded on an upper cover plate of the I beam through node plates, and the upper ends of the vertical web members and the inclined web members of the middle vertical truss sheet are welded on an upper chord member; the inclined web pipes on two sides are connected end to end and arranged in a W shape; and the two ends of each inclined web pipe are respectively welded with the upper chord member and the lower chord member. The truss type electric single-beam crane main beam reduces the weight of an electric single-beam crane, enhances the whole stability and lateral bending resistance of the electric single-beam crane, improves the safety performance of the crane, has a larger bearing capacity than the bearing capacity of a welding box-shaped main beam, is smooth and beautiful in appearance, and is particularly applicable to the conditions with small hoisting weight and large span.

Description

Truss-like mono beam overhead crane girder
One, technical field
The utility model belongs to the crane structure designing technique, is specifically related to a kind of mono beam overhead crane girder.
Two, background technology
The girder form of the mono beam overhead crane of domestic production at present adopts the welding box type construction usually.The advantage of the girder of this kind form is easy to process, and production efficiency is high.But it is bigger to conduct oneself with dignity, and is prone to the forfeiture resistance to overturning, particularly for high and narrow beam, in case it in the distortion of horizontal plane generation lateral buckling, then can lose load-carrying capacity.
Three, summary of the invention
The purpose of the utility model provides a kind of truss-like mono beam overhead crane girder, to improve the resistance to overturning of mono beam overhead crane.Truss-like mono beam overhead crane girder adopts the triangular truss structure; Constitute by H-girder, bottom level truss sheet, middle vertically truss sheet and the welding of two skew back cornicals; The straight web member of bottom level truss sheet and diagonal web member are welded on through gusset plate on the web of H-girder, and the outer end of straight web member and diagonal web member is welded on the lower boom; The middle vertically straight web member and the diagonal web member lower end of truss sheet are welded on through gusset plate on the upper cover plate of H-girder, and straight web member and diagonal web member upper end are welded on the top boom; The end to end W of the being shape of two skew back cornicals is arranged, and weld with top boom and lower boom respectively at every oblique cornical two ends.
Contrast welding box girder formula mono beam overhead crane girder the utlity model has following advantage:
1, adopts the truss-like girder, reduced the deadweight of mono beam overhead crane;
2, the triangular structure of girder has been strengthened the resistance to overturning and the side direction flexing resistance of mono beam overhead crane, has improved the safety performance of hoisting crane;
3, the mono beam overhead crane under the equivalent weight, the truss-like girder is bigger than the bearing capacity of welding box girder;
4, the truss-like mono beam overhead crane is particularly useful for the situation that hoisting capacity is little, span is big;
5, truss-like mono beam overhead crane profile is smooth, attractive in appearance.
The utility model all shows outstanding preceence from economy, safety and appearance design aspect.
