After weight pound plate 101 and the first hanger 102 are welded in place, bore hole processing need to be carried out to perforate, and open up chamfering.The bottom of girder 103
Portion sets several second hangers 104, the second hanger 104 connection steel box-girder.In the illustrated embodiment, in the bottom of girder 103
There is provided four the second hangers 104.Four the second hangers 104 are matched by combination of two, can make up with different spacing
Combination.These have the steel box-girder that the combination of different spacing can adapt to different length.With continued reference to shown in Fig. 1, each
Two hangers 104 include two shackle plates be arrangeding in parallel, have weight pound plate on shackle plate.Lifting equalizer bar 111 is connected to second
On hanger 104.Fig. 3 discloses the structure that equalizer bar is lifted by crane in the hanging beam according to the steel box-girder of an embodiment of the present utility model
Figure.As shown in figure 3, the tabular that lifting equalizer bar 111 is triangular in shape, top have connecting hole, bottom has lifting eye.Illustrating
Embodiment in, lifting equalizer bar 111 bottom is provided with two groups of lifting eyes, and the quantity of each group of lifting eye is two.So exist
The bottom of each lifting equalizer bar 111 has four lifting eyes.Two groups of four lifting eyes enable lifting equalizer bar 111 more
Various sizes of steel box-girder is adapted to well.In one embodiment, lift by crane and all pacify on connecting hole and lifting eye on equalizer bar 111
Equipped with weight pound plate, and carry out Boring.Fig. 1 is returned to, the connecting hole of lifting equalizer bar 111 passes through pivot pin 107, the and of axle sleeve 106
Bolt 108 is connected between two shackle plates be arrangeding in parallel so that lifting equalizer bar 111 is connected on the second hanger 104.Pin
Axle 107, axle sleeve 108 are finished, and ensure the fit tolerance with the hole on the second hanger 104 and lifting equalizer bar 111.Together
When, according to strength analysis calculation, bearing pin need to carry out surface hardening with proof strength.To ensure that each second hanger is being grouped
Concentricity during installation, after bearing pin 107 being inserted to the second hanger 102, then to the welding of the second hanger 102.
With reference to shown in figure 2, Fig. 2 discloses the plan structure of the hanging beam of the steel box-girder according to an embodiment of the present utility model
Figure.The hanging beam of the steel box-girder also includes auxiliary balance beam 109, and auxiliary balance beam 109 is connected to the side of girder 103.At one

The hanging beam of steel box-girder of the present utility model has the advantages of following：
1) using after hanging beam of the present utility model, by being changed to vertical pulling force by oblique pulling force when steel box-girder lifts by crane, reduce
Steel box-girder hanger reduces the generation of internal stress, steel box-girder overall structure is protected in side force caused by lifting.
2) steel box-girder is lifted by crane except internal field and also needs to consider outfield lifting, and using driving work compound, outfield is often adopted in internal field
Lifting operation is carried out with gantry crane.Vehicling operation is generally double hook or four hook operations, and gantry crane is often made for single hook
Industry.Hanging beam of the present utility model is suitable for different work requirement by adjusting intermediate equilibria beam.
3) different type steel box-girder length is inconsistent in same seat steel bridge.Hanger in girder lower end is two groups four altogether,
It is suitable for the steel box-girder of different length.Different steel box-girder hanger groups can be adapted to by adjusting hanger position of opening on small equalizer bar
Spacing.
4) the linkage operation of duplicate rows car is both needed to when being lifted by crane in steel box-girder workshop, safe spacing between driving be present, reference is existing
Conventional travelling data, the hanger spacing of girder upper surface two are arranged to 11 meters, meet the existing spacing requirement mainly driven a vehicle.
5) it is bolt connection between girder and equalizer bar, convenient disassembly.It is four rod members after the completion of dismounting, can conveniently adopts
Transported with fork truck.
Above-described embodiment, which is available to, is familiar with person in the art to realize or using of the present utility model, be familiar with ability
The personnel in domain can in the case where not departing from utility model thought of the present utility model, above-described embodiment is made various modifications or
Change, thus the scope of protection of the utility model is not limited by above-described embodiment, and should meet claims to mention
