Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, also may be used
To obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention；
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 embodiments of the invention, technical scheme is clearly and completely described, it is clear that
Described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the enforcement in the present invention
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of protection of the invention.
Shown in Fig. 1-3, bridge telescopic unit component, including portable plate 1 and fixed plate 2, one end of portable plate is comb
Increment 3, fixed plate 1 is connected by comb structure with portable plate 2.Comb structure entirety strides across beam-ends gap so that it is structure stress
Rationally, and durable in use.Comb end forms domatic, and the rubbish between comb is released by force by domatic comb, and taken away by driving,
Beam-ends gap will not be entered.Mutually intert between comb and arrange that each comb 6～8cm width intersects all the time when being subjected to displacement and do not takes off
From.Comb structure direction is consistent with vehicle pass-through direction, reduces impulsive force during wheel transition, makes driving smooth out.
Also include, displacement post main body 401, displacement post column jacket 402, displacement post inner prop 403 and displacement column base plate 404；Described
The displacement vertical center being installed on described displacement column base plate 404 of post main body 401；Described displacement post column jacket 402 is sheathed on described
Outside displacement post main body 401, fix with described displacement column base plate 404 and be connected；Described displacement post inner prop 403 is arranged at outside displacement post
At gap between post 402 and described displacement post main body 401, fix with described displacement column base plate 404 and be connected；At the bottom of described displacement post
Plate 404 is connected by bolt 405 with described portable plate 1；When described portable plate is squeezed, make the nose of comb of portable plate with displacement
Post main body 401 produces level angle for the center of circle.
Further at displacement post column jacket 402, vertical rotating packing ring 8 is set with portable plate 1 junction.When displacement column assembly 6
Extruding 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 extruding vertical rotating packing ring, the torsion of nose of comb can be met.
By L-type shape bolt, portable plate 1 being installed on bridge movable part 101, fixed plate 2 is bolted to bridge by L-type
Beam fixed part 102.Bridge movable part 101 matches with bridge fixed part 102.Lower surface and bridge movable part at portable plate 1
101 junctions arrange rubber sheet gasket 9.The side surface of portable plate 102 and described bridge movable part 101 junction arrange rubber strip
10.Between vehicle and retractor device, when colliding between the internal each parts of retractor device, it is possible to play good vibration damping and make
With, reduce vehicle by time noise；
And designed by vertical rotating packing ring and rubber sheet gasket etc. so that device and beam body are for flexibly connecting, and load impacts
Power is absorbed by elastomeric material and transmits, and significantly weakens beam body vibration, the deformation destruction to retractor device, and anti-fatigue performance is bright
Show and be superior to other structures.
In fixed plate 2 lower end, arranging steel plate 11, steel plate 11 uses rustless steel.At steel plate 11, lower floor arranges canvas rubber slab
12, canvas rubber slab 12 lower surface is fitted with bridge fixed part 102.The upper surface of steel plate 11 pastes with the lower surface of comb structure
Close, make bridge telescopic unit component and steel plate be close to continuously, will not be invaded by rubbish.
Bridge fixed part 102 and bridge movable part 101 connect and arrange waterstop 13 at gap, waterstop 13 material selection sail
Cloth rubber.Rainwater is automatically imported waterstop 13 by device after bridge floor spilled water hole is drained and discharges, and water resistance is preferable.Waterstop
Use canvas rubber, be difficult to aging breakage.And it being positioned at gap, it is to avoid sunlight irradiates aging.
Bridge extension joint is to use above-mentioned bridge telescopic unit component to assemble.During assembling, along bridge to installation, each
The width of bridge telescopic unit component is 1m, can also design other width according to demand.Wherein, bridge movable part can be beam
End, bridge fixed part can be another corresponding beam-ends.Or bridge movable part can be beam-ends, bridge fixed part is bridge
Platform, is installed on relevant position according to demand.Level angle and torsional deflection is made to be evenly distributed to each bridge flexible single
In unit's component, actively adapt to the displacement of bridge, guaranteed that device runs well.Need due to the reason such as aging when retractor device
During reparation, only individually disassembling, assembling and replacing damages bridge telescopic unit component.The operation of one lane width is set at direction across bridge
Face, can modular repair in the case of uninterrupted traffic so that operation cost reduces, remarkable benefit.And fill with modulus type
Putting and install with the same Life Calculation of valency, operation cost is only the 1/5 of modulus type.The performance ginseng of the bridge extension joint after installing
Maximum horizontal frictional resistance≤5kN/m when number is for stretching, compressing.When stroke is 80mm～720mm, stretch, maximum when compressing
Vertical deviation be≤1.0mm, when stroke is 800～1440mm, stretches, maximum vertical deviation is≤1.3mm when compressing, and stretches
When amount is 1520～2240mm, stretch, maximum vertical deviation is≤1.6mm when compressing, and when stroke is 2320～3000mm, draws
Stretch, maximum vertical deviation is≤1.9mm when compressing.Allow corner deviation, vertical corner≤0.005rad, level angle≤
0.005rad。
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art, in the technical scope that the invention discloses, can readily occur in change or replace, should contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should described be as the criterion with scope of the claims.
