Description

A kind of debounce comb teeth shape bridge extension joint
Technical field
The utility model relates to a kind of bridge extension joint, relates in particular to a kind of comb teeth shape bridge extension joint that prevents tooth plate knock-on.
Background technology
At present, because comb plate type stretching device has the advantages such as driving is smooth-going, impact force is little, noise is little and fitting depth is more shallow, at highway bridge, find broad application.But traditional comb plate type stretching device, vehicle mobile load passes to tooth plate by tire, and tooth plate passes to beam basis by holder and bolt, and bolt bears fluctuating load, and being prone to fatigue failure affects traffic safety; When vehicle front-wheel passes through fast, load removal, stress sudden outburst, lift in tooth plate generation reflex action distortion, easily occurs puncturing rear tyre, affects traffic safety simultaneously.
Utility model content
The purpose of this utility model is: provide a kind of structure of tooth plate reflex action distortion while preventing from unloading, for comb-type telescoping device.
The purpose of this utility model realizes by following technical proposals:
A debounce comb teeth shape bridge extension joint, comprises holder, and is fixed on the folding tooth plate on described holder, between described folding tooth plate and holder, is provided with vibration isolation plate.
In such scheme, between holder and folding tooth plate, vibration isolation plate is set, when folding tooth plate is stressed, vibration isolation plate produces distortion, absorbs energy, reduce the impact stress of wheel mobile load to holder, Condition of Sudden Unloading restores after vibration plate, and folding tooth plate stress release, due to the damping action of vibration isolation plate, the distortion of folding tooth plate is little, prevents from lifting in reflex action distortion.
As selecting 1, between described folding tooth plate afterbody and holder, be also provided with the position-limit mechanism of coupling.
In such scheme, by position-limit mechanism, limit moving up and down of the relative holder of folding tooth plate, bear the moment of flexure of wheel load to tooth plate, avoid moment of flexure to pass to fixedly set bolt and the beam basis of driving tooth plate and holder, reduce the fatigue load on bolt and beam basis, prevent coming off, damage and basic destruction of bolt.Position-limit mechanism those skilled in the art are known various implementations, as long as can realize aforementioned spacing all in the protection domain of the technical program.
As the further selection 2 of selecting 1, described position-limit mechanism is notch and the boss structure matching.
As the further selection 3 of selecting 2, the corresponding folding tooth plate of described holder tail position is provided with notch, and described folding tooth plate afterbody is a boss structure, and this boss structure stretches in described holder notch and with its size and mates.
In such scheme, as exemplifying, preferred notch and boss structure, notch and boss structure are feasible too at holder and the exchange of folding tooth plate tail position simultaneously.
As the further selection 4 of selecting 1, described position-limit mechanism is spacing hole and the pin shaft structure matching.
As the further selection 5 of selecting 1, the corresponding folding tooth plate of described holder tail position is provided with some spacing holes, and described folding tooth plate afterbody correspondence is provided with some pin shaft structures, and this pin shaft structure correspondence stretches in described holder spacing hole and with its size mates.
In such scheme, as exemplifying, preferred spacing hole and pin shaft structure, spacing hole and pin shaft structure are feasible too at holder and the exchange of folding tooth plate tail position simultaneously.
As selecting 6, described vibration isolation plate is rubber tile.
The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form a plurality of schemes; be the utility model and can adopt also claimed scheme: as the utility model; each selects to select any combination with other; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program; be the claimed technical scheme of the utility model, at this, do not do exhaustive.
The beneficial effects of the utility model:
1, can effectively prevent that vehicle from passing through fast, the tooth plate reflex action distortion that stress sudden outburst causes.
2, fixedly the set bolt of holder and folding tooth plate does not bear fluctuating load, can not produce fatigue failure and causes bolt looseness or break, and the life-span is long.
When 3, vehicle passes through, impact force is little, and steadily, noise is little in driving.
