Description
Technical field
The invention belongs to crane field, and in particular to a kind of crane girder, more particularly to a kind of light crane
Girder.
Background technology
Girder is one of most important part of crane complete machine structure, and main beam structure form mainly has box beam, girder truss, honeybee
Nest beam, box beam mainly carry out the case structure of welding processing by steel plate or I-shaped steel raw material, and it has safe and reliable
Property high, the advantageous feature such as rigidity is big, but the crane of box-beam structure exists relatively costly, from great, wind resistance is relatively poor
Weak point, Honeycomb Beam main side face be isosceles triangle, have honeycomb hole, top and the bottom to have chord member on two skew back waists, adopt
Steel plate is welded, and deadweight and cost are all higher, and girder truss is generally processed by welding procedure using angle steel or I-steel,
Because having low cost, from heavy and light, the advantage such as wind resistance is good and be widely applied, but girder frame structure have rigidity little,
The shortcoming of stability difference is to adapt to across huge, lifting is high, large-tonnage crane use occasion, there is provided a kind of lightweight, rigidity
Greatly, the girder truss of good stability is necessary.
Content of the invention
The invention aims to overcoming the deficiencies in the prior art, and a kind of simple structure is provided, lightweight, operation is steady
Fixed, rigidity is big, easy to process, crane girder with low cost.
The object of the present invention is achieved like this：A kind of light crane girder, it include upper side, described upside
Face is made up of chord member A, chord member B, cross bar and support bar, and described chord member A and chord member B be arranged in parallel, and described upper side is distinguished
Downside is connected to by prism A, prism B, described downside is made up of chord member C, chord member D, cross bar and support bar, institute
The chord member C and chord member D for stating be arranged in parallel, and each parallel to chord member A and chord member B, described prism A is by cross bar A, cross bar B, web member
A and web member B is constituted, and described cross bar A is located in upper side, and described cross bar A two ends are respectively perpendicular and are connected to chord member A and chord member
B, described cross bar B are located in downside, and described cross bar B two ends are respectively perpendicular and are connected to chord member C and chord member D, and described is oblique
Side B is made up of cross bar A, cross bar C, web member C and web member D, and described cross bar C is located in downside, described cross bar C two ends point
Chord member C and chord member D is not vertically connected to, it is be arranged in parallel with cross bar B, described prism A, prism B and downside are constituted
Equilateral triangle structure, the bottom surface of described equilateral triangle structure is by cross bar B, cross bar C, cross bar D, support bar A and support bar B structures
Into described cross bar D is located in downside, and described cross bar D two ends are respectively perpendicular and are connected to chord member C and chord member D, and described props up
Strut A and support bar B are located in downside respectively, and one end of described support bar A is connected on chord member C, is connected to cross bar B
One end, the other end of described support bar A are connected on chord member D, are connected to one end of cross bar D, one end of described support bar B
It is connected on chord member C, is connected to one end of cross bar C, the other end of described support bar B is connected on chord member D, is connected to cross bar
One end of D, described support bar A, support bar B and chord member C constitute isosceles triangle, and described cross bar D one end is connected to this etc.
The top of lumbar triangle shape, its other end are connected to the midpoint on the isosceles triangle base, described equilateral triangle inside configuration
Hound B is provided with, one end of described hound B is connected on chord member B, is connected to one end of cross bar A, described hound
The other end of B is connected on chord member D, is connected to one end of cross bar D, and the equilateral triangle adjacent with described equilateral triangle structure is tied
Hound A is provided with inside structure, and described hound A and hound B is vertically arranged.
Described chord member A, chord member B, chord member C and chord member D are rectangular steel tube.
Described cross bar, web member and support bar are I-steel.
Described hound is angle steel.
Described cross bar, web member, the connected mode of hound and support bar and chord member are welding.
Beneficial effects of the present invention：The present invention adopts four rectangular steel tubes as the basic framework of chord member trussed girder,
Two support bars for intersecting that cross bar connected with cross bar are respectively adopted in the upper and lower side of girder truss framework is connected to chord member, front
Two intersecting web members being respectively adopted on trailing flank and being connected to chord member, cross bar, web member and chord member constitute equilateral triangle structure, overall
From the point of view of, girder truss is made up of a series of equilateral triangle structures, increased the stability of girder truss, and in each positive triangle
One hound is set inside shape, and the setting direction of the hound of the adjacent equilateral triangle in left and right is different, and this design more increases
The rigidity of girder truss and stability, in addition, chord member is higher using square bar stability, web member, support bar, cross bar adopt I-shaped
Steel, hound are designed using angle steel, can be mitigated the weight of whole girder, can be lifted more large-tonnage weight, cross bar, abdomen
