In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, comes for those of ordinary skill in the art
Say, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A direction view of Fig. 1；
Fig. 3 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is carried out clear, complete
Ground describes, it is clear that described embodiment is only a part of embodiment of this utility model rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creation
Property work premise under the every other embodiment that obtained, broadly fall into the scope of this utility model protection.
Shown in Fig. 1-3, bridge telescopic unit component, including portable plate 1 and fixed plate 2, portable plate
One end is nose of comb 3, and fixed plate 1 is connected by comb structure with portable plate 2.Comb structure entirety strides across beam
End gap so that it is structure stress is reasonable, and durable in use.Comb end forms domatic, the rubbish between comb
Released by force by domatic comb, and taken away by driving, beam-ends gap will not be entered.The most interspersed cloth between comb
Put, each comb 6～8cm width, intersect all the time when being subjected to displacement without departing from.Comb structure direction and vehicle lead to
Line direction is consistent, reduces impulsive force during wheel transition, makes driving smooth out.Centre bolt 4 sequentially passes through work
Dynamic plate 1, bolt support 5 and displacement column assembly 6, live with portable plate, bolt support and displacement column assembly
It is dynamically connected.Centre bolt 4 and bolt support 5 are played a protective role by displacement column assembly 6, it is to avoid in
The material contacts such as heart bolt 4 or bolt support 5 and cement, reduce abrasion and make the overall structure can be suitable
Freely complete rotational action.Both ends of the surface can be descended thereon rotation layer 7 to be set or appoints up and down at bolt support 5
End face arranges rotation layer 7, is preferably respectively provided with rotation layer 7 in upper and lower both ends of the surface.The material rotating layer 7 is
Politef, when portable plate 1 extruding rotates layer 7, nose of comb 3 can be with centre bolt 4 as the center of circle
Produce level angle.Thus adapt to the change of bridge upper lateral rotation displacement.Further at displacement column assembly 6
Vertical rotating packing ring 8 is set with portable plate 1 junction.When displacement column assembly 6 extrudes vertical rotating packing ring 8,
Vertical rotating packing ring 8 deformation, thus meet nose of comb and produce vertical corner.When there is distortion, by squeezing
Pressure vertical rotating packing ring and rotation layer, can meet the torsion of nose of comb.Employing metal material can also be set
The displacement protective housing of matter, covers the swing system that centre bolt, bolt support and displacement column assembly form
Protect so that it is independently separate with concrete support system, make both stress independent of one another, be independent of each other.
By bolt, portable plate 1 being installed on bridge movable part 101, fixed plate 2 is bolted to bridge
Beam fixed part 102.Wherein, bolt is preferably L-type bolt.Bridge movable part 101 and bridge fixed part
102 match.Lower surface at portable plate 1 arranges rubber sheet gasket 9 with bridge movable part 101 junction.Live
The side surface of dynamic plate 102 arranges rubber strip 10 with described bridge movable part 102 junction.When vehicle is with flexible
Between device, when colliding between the internal each parts of retractor device, it is possible to play good damping effect,
Reduce vehicle by time noise；
And by vertical rotating packing ring and rubber sheet gasket etc. design so that device and beam body for flexibly connecting, lotus
Carry impulsive force absorbed by elastomeric material and transmit, significantly weaken beam body vibration, deformation to retractor device
Destroying, anti-fatigue performance is substantially superior to other structures.
In fixed plate 2 lower end, arranging steel plate 11, steel plate 11 uses rustless steel.Arrange in steel plate 11 lower floor
Canvas rubber slab 12, canvas rubber slab 12 lower surface is fitted with bridge fixed part 102.The upper table of steel plate 11
Face and the lower surface laminating of comb structure, make bridge telescopic unit component and steel plate be close to continuously, will not be by rubbish
Rubbish invades.
Bridge fixed part 102 and bridge movable part 101 connect and arrange waterstop 13 at gap, waterstop 13 material
Matter selects canvas rubber 12.Rainwater is automatically imported waterstop 13 by device after bridge floor spilled water hole is drained and discharges,
Water resistance is preferable.Waterstop uses canvas rubber, is difficult to aging breakage.And it is positioned at gap, it is to avoid sun
Light irradiates aging.
Bridge extension joint is to use above-mentioned bridge telescopic unit component to assemble.During assembling, along bridge to peace
Dress, the width of each bridge telescopic unit component is 1m, can also design other width according to demand.Wherein,
Bridge movable part can be beam-ends, and bridge fixed part can be another corresponding beam-ends.Or bridge is movable
Portion can be beam-ends, and bridge fixed part is abutment, is installed on relevant position according to demand.Make level angle
It is evenly distributed in each bridge telescopic unit component with torsional deflection, actively adapts to the displacement of bridge,
Guaranteed that device runs well.When retractor device needs to repair due to the reason such as aging, the most individually dismount
Change and damage bridge telescopic unit component.The scope of operation of one lane width is set at direction across bridge,
Modular repair in the case of uninterrupted traffic so that operation cost reduces, remarkable benefit.And with modulus
Formula device is installed with the same Life Calculation of valency, and operation cost is only the 1/5 of modulus type.Bridge after installing is stretched
Maximum horizontal frictional resistance≤5kN/m when the performance parameter of compression apparatus is for stretching, compressing.Stroke be 80mm～
During 720mm, stretch, maximum vertical deviation is≤1.0mm when compressing, when stroke is 800～1440mm,
When stretching, compression, maximum vertical deviation is≤1.3mm, when stroke is 1520～2240mm, stretches, presses
During contracting, maximum vertical deviation is≤1.6mm, when stroke is 2320～3000mm, stretches, maximum when compressing
Vertical deviation is≤1.9mm.Allow corner deviation, vertical corner≤0.005rad, level angle≤0.005
rad。
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is also
Be not limited to this, any those familiar with the art in the technical scope that this utility model discloses,
Change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Therefore, this reality
Should described be as the criterion with scope of the claims with novel protection domain.
