Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the right view (concealing longitudinal oil cylinder) of Fig. 1.
Specific embodiment
As shown in Figure 1, 2, bracket is packed in high-speed rail Bridge Erector transition described in the utility model, including along beam car vehicle frame 1
Width direction is fixed thereon the lower beam assembly 2 on surface, and lower beam assembly 2 is spirally connected by high-strength bolt is fixed on beam car vehicle
1 upper surface of frame；A pair of telescopic lifting column 3, the spacing between two lifting columns 3 are arranged at intervals on lower beam assembly 2
Depending on the width of the width of Bridge Erector 13 and beam car vehicle frame 1, generally 2.38m, the upper bush upper end of two lifting columns 3
It is linked together by the upper beam assembly 4 that level is set up；A pair of of phase is provided at two close end in the upper surface of upper beam assembly 4
Mutually symmetrical rubber cushion blocks 5,5 upper supporting frame bridge machine 13 of rubber cushion blocks, increasing friction force enhance stability.To further prevent
Lateral sliding during transition of Bridge Erector 13 falls, and 4 upper surface of upper beam assembly on the outside of two rubber cushion blocks 5 is along its width
Direction is provided with Bridge Erector blend stop 12, and two Bridge Erector blend stops 12 are located at the upper surface both ends of upper beam assembly 4.
Uniform intervals offer several pairs of pin holes 6, each pair of pin hole along longitudinal direction on the lower sleeve lateral wall of two lifting columns 3
6 two holes are in same horizontal line；There is oil cylinder joist by 7 horizontal connection of connecting pin being arranged in a pair of of pin hole 6
8, a pair of longitudinal oil cylinder 9, the upper end of longitudinal oil cylinder 9 and the upper bush outer wall phase of lifting column 3 are arranged at intervals on oil cylinder joist 8
It is hinged, longitudinal oil cylinder 9 is driven by the pumping plant 14 being arranged on beam car vehicle frame 1, and the upper bush of lifting column 3 is driven to transport above and below
It is dynamic, to complete the adjustment to 13 height of Bridge Erector；In addition, stability when adjusting 13 height of Bridge Erector above and below to improve, two
Longitudinal oil cylinder 9 is respectively arranged at the front and rear sides of lifting column 3 (before the direction of advance of beam car is, direction of retreat is rear).
Two lifting columns 3 upper bush at lower end level be equipped with and be adapted to the shop bolt 10 of grafting with pin hole 6,
Shop bolt 10 is used to fix the upper bush and upper beam assembly 4 of lifting column 3；In addition, being carried on the back to further increase lifting column 3
Stability when fortune is hinged with the telescopic auxiliary branch tilted down in the upper bush of two lifting columns 3 respectively at upper end
Strut 11, auxiliary support bar 11 are located at the rear side of lifting column, and lower end is mutually hinged with 1 upper surface of beam car vehicle frame.
For the height for being adapted to Bridge Erector 13, prop up convenient for Bridge Erector 13 on upper beam assembly 4, lifting column 3 is trapped
Cylinder height is 4m, and pin hole 6 opens up 13 pairs along the lower sleeve short transverse uniform intervals of lifting column 3, between adjacent two pairs of pin holes 6
Distance of center circle be 300mm, i.e. each regulated quantity of oil cylinder joist 8 is 300mm, and the upper bush of lifting column 3 is then by longitudinal oil
Cylinder 9 drives it to carry out height fine tuning；Upper beam assembly is adjusted by the fixation position of longitudinal oil cylinder 9 and transformation oil cylinder joist 8
Height, achieve the purpose that adjust pack 13 height of Bridge Erector.
In actual use, it is respectively provided at forward and backward two sections in the upper surface of beam car vehicle frame 1 and packs bracket, two groups are carried on the back
The common support Bridge Erector 13 of bracket is transported, according to circumstances adjusts the height of Bridge Erector 13, concrete operations are first by shop bolt 10
Insertion, and connecting pin 7 is extracted out, the upper end of longitudinal oil cylinder 9 is fixed together in company with the upper bush of lifting column 3 at this time, at lower end
In release conditions；Then longitudinal oil cylinder 9 is adjusted by pumping plant 14 and extends 300mm or 600mm, is i.e. oil cylinder joist 8 moves down
300mm or 600mm；The fixed oil cylinder joist 8 of insertion connecting pin 7 later extracts shop bolt 10 and discharges the upper of longitudinal oil cylinder 9
End；Control longitudinal oil cylinder 9 again by pumping plant 14 later and shrink 300mm or 600mm, upper beam assembly 4 and Bridge Erector 13 also with
Longitudinal oil cylinder 9 declines 300mm or 600mm together；By multiple above-mentioned repetitive operation, can reach reduces by 13 height of Bridge Erector
Purpose, when raising, are operated in the reverse procedure, minimum the height of Bridge Erector 13 to be reduced 1.8m, facilitate transition
And u-turn, it is ensured that stability when packing and passability when crossing tunnel, the peace for reducing Bridge Erector 13 are torn workload open, saved big
Human and material resources are measured, efficiency of setting a roof beam in place is improved.
