The utility model discloses public road bridge for roof beam scour protection hit telescoping device utilizes the device to absorb lorry striking energy, conducts to the viscoelastic attenuator on through blocking the cable, introduces the earth with kinetic energy, and the rapid fast car kinetic energy of reduceeing makes the car stagnation of movement, avoids the superelevation car to the impact damage of public road bridge roof beam, and fundamentally guarantees the safety of bridge.
Description
Technical field
This utility model relates to Anti-knocking telescopic equipment field, is specially a kind of highway bridge Anti-knocking retractor device.
Background technology
When on highway by superelevation (exceeding height at the bottom of overpass beam beam) automobile, the major accident that automobile bumps against with bridge often occurs, highway bridge beam body is damaged, bridge collapse is caused time serious, jeopardize the traffic safety of highway, at present, bridge protective frame, mostly adopt rigid structure, make with shaped steel or steel-pipe welding, when automobile bumps against with bridge protective frame, the enormous impact power that moment produces makes protective frame damage, automobile under the effect of inertia it is possible to strike beam body, the safety of bridge can not be guaranteed, protective frame is frequently bad by damage, repairing recovers to need substantial amounts of manpower and materials.
Utility model content
The purpose of this utility model is in that to provide a kind of highway bridge Anti-knocking retractor device, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of highway bridge Anti-knocking retractor device, including viscoelastic damper, buffing pad, A-frame, intercept cable wire, suspension cable, bridge and bridge pier, described viscoelastic damper is arranged on the left side bottom bridge, described buffing pad is arranged on bridge two bottom sides, described A-frame is arranged on buffing pad, described viscoelastic damper is connected with bridge pier through A-frame by intercepting cable wire, described A-frame top is connected with intercepting cable wire by suspension cable, described bridge pier is arranged on the right side bottom bridge.
Preferably, described viscoelastic damper by viscoelastic body, back-moving spring, buckle and form with shell, and viscoelastic body is arranged on the inwall of shell, and back-moving spring is arranged on enclosure, buckles and is connected with back-moving spring by cover top portion.
Preferably, described A-frame is fixed on buffing pad by high-strength bolt.
Preferably, described viscoelastic damper is fixed in concrete foundation by anchoring bolt, is fixed in concrete foundation by anchoring bolt bottom buffing pad.
Compared with prior art, the beneficial effects of the utility model are: this highway bridge Anti-knocking retractor device, viscoelastic damper is installed bottom bridge, A-frame is fixed on bridge by high-strength bolt, viscoelastic damper is fixed in concrete foundation by anchoring bolt, it is fixed in concrete foundation by anchoring bolt bottom buffing pad, play fixing supporting role, viscoelastic damper is by absorbing truck Impact energy, by blocking rope conduction to viscoelastic damper, kinetic energy is introduced the earth, rapid speed cuts down automobile kinetic energy, make automobile stagnation of movement, avoid the superelevation automobile impact damage to highway bridge, fundamentally ensure the safety of bridge.
Accompanying drawing explanation

In figure: 1, viscoelastic damper, 2, buffing pad, 3, A-frame, 4, intercept cable wire, 5, suspension cable, 6, bridge, 7, concrete foundation, 8, bridge pier, 9, viscoelastic body, 10, back-moving spring, 11, buckle, 12, shell.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1 and Fig. 2, this utility model provides a kind of technical scheme: a kind of highway bridge Anti-knocking retractor device, including viscoelastic damper 1, buffing pad 2, A-frame 3, intercept cable wire 4, suspension cable 5, bridge 6, concrete foundation 7, bridge pier 8, viscoelastic body 9, back-moving spring 10, buckling 11 and shell 12, viscoelastic damper 1 is arranged on the left side bottom bridge 6, and viscoelastic damper 1 is by viscoelastic body 9, back-moving spring 10, buckle 11 and shell 12 form, and viscoelastic body 9 is arranged on the inwall of shell 12, it is internal that back-moving spring 10 is arranged on shell 12, buckle 11 to be connected with back-moving spring 10 by shell 12 top, buffing pad 2 is arranged on bridge 6 two bottom sides, A-frame 3 is arranged on buffing pad 2, viscoelastic damper 1 is connected with bridge pier 8 through A-frame 3 by intercepting cable wire 4, A-frame 3 top is connected with intercepting cable wire 4 by suspension cable 5, bridge pier 8 is arranged on the right side bottom bridge 6, viscoelastic damper 1 is fixed in concrete foundation 7 by anchoring bolt, is fixed in concrete foundation 7 by anchoring bolt bottom buffing pad 2.
Operation principle: when superelevation car crass intercepts cable wire 4, impact load can cause interception cable wire 4 to deform, load force is along intercepting cable wire 4 center conductive to viscoelastic damper 1, viscoelastic body 9 in viscoelastic damper 1 can produce a viscosity and elastic reaction, both interact, bump stroke disappears under the effect of viscoelastic damper 1 counter-force, reach to block and stop automobile and avoid the purpose of car crass overpass beam, after automobile exits, intercept the memory that cable wire 4 utilizes the elastic force of spring and viscoelastic body 9 itself to have, interception cable wire 4 is driven to reset, recover to protecting state normally.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; it is equal to replacement according to the technical solution of the utility model and improvement design thereof or is changed, all should be encompassed in protection domain of the present utility model.
