Grand bridge 2-90m superimposed arch in railway new construction Wild Goose and Reed Marsh Mountains, Zhejiang, Taiwan and Wenzhou is positioned at Wild Goose and Reed Marsh Mountains, national scenic spot, be bright spot engineering, key project and the Control Engineering of Zhejiang, Taiwan and Wenzhou railway, in speedway mileage DK215+200 position, Zhejiang, Taiwan and Wenzhou, on stride the Zhejiang, Taiwan and Wenzhou at a high speed, the right angle of cut is about 23.5 °.Steel case beam adopts single case nine Room equal altitudes box sections.The wide 14.8m of steel case end face, the wide 12.6m in bottom surface, part, central bearing point place is 13.1m, the high 2.2m of girder steel cross section midline case, case end face laterally establish two-way 2% sluicing slope; Steel case beam length overall 184m, heavily about 2400t.To how long and large steel box girder like this set up and to put in place, guarantee that it sets up precision, have higher requirement to guarantee workmanship.
By the linear control in steel box girder assembling, the pushing tow process, force-bearing situation are carried out labor, discovery is in loading process, owing to be subjected to the influence of glide path structure and temporary rest pier beam structure, four glide paths and a slideway length direction counter-force distributed pole on section are inhomogeneous, cause steel case beam local stress can not satisfy code requirement.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of adjustable synchronous hydraulic mount slideway is provided, at setting up of long and large steel box girder, on its glide path fulcrum, adopt the adjustable synchronous hydraulic mount, automatic adjusting by the hydraulic pressure top, the counter-force of cantilever end fulcrum is assigned on each glide path fulcrum more equably, and can be in the pushing tow process by regulating the fulcrum height downwards, thereby reduce local stress and horizontal force that support reaction reduces steel case beam, the safety of girder construction and the safety of temporary rest pier when guaranteeing pushing tow guarantee that steel case back pushes away that local stress satisfies code requirement in the process.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model adjustable synchronous hydraulic mount slideway is that the glide path fulcrum is set is hydraulic jack, the all hydraulic jack is provided with in parallel on each glide path in the same cross section, the parallel way of described hydraulic jack is that oil return opening parallel with one another with the oil-in of each hydraulic jack, each hydraulic jack is parallel with one another, shared same the oil pump that is used to control its counter-force of described each hydraulic jack; Setting forms a glide path fulcrum by glide path pallet of the common supporting of two hydraulic jack.
The design feature of the utility model adjustable synchronous hydraulic mount slideway also is:
Between described hydraulic jack and glide path pallet, adopt the globular hinge structure to connect; Glide path slide plate bearing is placed on the described glide path pallet and forms glide path.
In a described glide path fulcrum, be respectively arranged with articulated joint in the globular hinge structure between two hydraulic jack and the glide path pallet, the articulated joint of one of them is the anchor tip of fixedlying connected with the glide path pallet, another is to slide in the glide path pallet, and described slip is subjected to the spacing slip joint of both sides positive stop.
It is the hydraulic support jack that the utility model is provided with the glide path fulcrum, four all jack of glide path are controlled by same table oil pump on the same cross section, be arranged in parallel between all jack on the same cross section, realize that lotus, unified oil return are held in unified control, the unification of each jack on the same cross section of all glide paths, guarantee the stressed even of each glide path fulcrum, thereby the internal force of the steel case beam that evenly distributed effectively, and can be by reducing oil pressure to reduce support height, to reduce counter-force, thereby further reduce the internal force of steel case beam, guaranteed the quality of steel case beam.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, technical solutions of the utility model are practical, by on the glide path fulcrum, adopting the utility model hydraulic mount, make steel case stress beam be no more than code requirement, and, stressed even on four glide paths in same cross section, can also counter-force effectively be transmitted to the back-end by reducing the fulcrum height, play the effect that reduces the front end total reaction, reached the set goal.
2, the utility model does not increase ancillary method, does not need steel case beam is carried out reinforcement, can reduce steel case back effectively and push away internal force in the process, and constructing operation is simple, effect is higher.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 hydraulic jack, 2 glide path pallets, 3 globular hinge structures, 31 anchor tips, 32 slip joint, 4 glide path slide plate bearings, 5 pier roof rail, 6 positive stops.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, it is hydraulic jack 1 that the glide path fulcrum is set, all hydraulic jack 1 is provided with in parallel on each glide path in the same cross section, the parallel way of hydraulic jack 1 is that oil return opening parallel with one another with the oil-in of each hydraulic jack, each hydraulic jack is parallel with one another, each hydraulic jack 1 shared same control oil pump that is used to control its counter-force.
Shown in Figure 1, in the present embodiment, be provided with by glide path pallet 2 of two hydraulic jack, 1 common supporting and form a glide path fulcrum, between hydraulic jack 1 and glide path pallet 2, adopt globular hinge structure 3 to connect; Glide path slide plate bearing 4 is placed on the glide path pallet 2 and forms glide path.For such supporting form, four glide paths on the same cross section, promptly four glide path fulcrums need be provided with totally eight hydraulic jack altogether, and all these eight jack are connected in parallel, and are controlled by same table oil pump.
