Abstract

A bridge buffering anti-collision device comprises a protecting plate, a fixed plate, buffering blocks and a supporting base, the buffering blocks are arranged between the protecting plate and the fixed plate through bolts, the fixed plate is of a trapezoidal structure, two sides of the fixed plate are fixed on the protecting plate through bolts, and the supporting bases are arranged on two sides of the protecting plate. According to the bridge buffering anti-collision device, when the protecting plate deforms by being impacted, the buffering blocks can play a role in absorbing energy and relieving impact force; the fixed plate has a certain distance from a boundary bam of a bridge, so that a certain buffering deformation space is formed between the whole fixed plate and the boundary beam of the bridge. When the bridge buffering anti-collision device is implemented, the vehicle facing surface of the protecting plate is coated with yellow and black reflecting marks, height limit and speed limit signs are arranged on the upper side of the protecting plate, ground speed brakes and other ancillary facilities are arranged, and therefore drivers are reminded to slow down and drive slowly beneficially, losses are avoided or reduced, and benefits are brought to vehicles, people, the anti-collision device and the bridge.

Description

A kind of bridge buffering anti-collision device
Technical field
The utility model belongs to highway traffic safety facility technology field, especially relates to a kind of bridge buffering anti-collision device.
Background technology
Along with socioeconomic fast development, vehicle on secondary highway (county road, backroad) is more and more, and vehicle develops into truck gradually by tricycle, agricultural vehicle, the speed of a motor vehicle also from slow to fast, vehicle body by short to height.Vehicle on secondary highway under while wearing Trunk highway highway bridge, under-clearance can not meet current requirement, cause vehicle cannot get through, not pre-decelerating of some vehicle, vehicle smashes the Frequent Accidents of bridge, and Trunk highway highway (particularly speedway) bridge main beam is by traffick scratch phenomenon is very general below at present.General way is that tens meters of of distance bridge arrange height-limiting gantry on secondary highway at present; known height-limiting gantry generally adopts rigid structures; vehicle knocks rear vehicle and receives damage together with portal frame; once portal frame is damaged; bridge just loses protection; cart afterwards will directly bump against on bridge, jeopardizes bridge health safety.
Utility model content
The utility model has designed a kind of bridge buffering anti-collision device in order to address the above problem; its object is: provide a kind of simple in structure; maintenance and installation is easy to use, has both protected to a certain extent bridge not smashed, and can alleviate again the bridge buffering anti-collision device of amount of vehicle damage.
The utility model technical solution:
A kind of bridge buffering anti-collision device, comprise protected apron, fixed head, buffer stopper and supporting seat, it is characterized in that: described buffer stopper is arranged between protected apron and fixed head by bolt, fixed head is trapezium structure, fixed head both sides are bolted on protected apron, and described supporting seat is arranged on protected apron both sides.
8~20 buffer stoppers are installed between described protected apron and fixed head.
On described protected apron, be coated with yellow black alternate reflecting marking, protected apron top is provided with limit for height, speed(-)limit sign.
Described protected apron adopts No. 40 channel-section steels, and described fixed head material is steel plate.
Described supporting seat is made up of cross bar, large flange and small flange plate, cross bar one end is connected with small flange plate, and the other end is connected with large flange, is provided with rectangle bolt hole on described small flange plate, and be connected with protected apron by bolt, large flange is bolted on bridge pier (platform) cap.
Between described cross bar and horizontal plane, angle is 0~30 degree.
The beneficial effects of the utility model:
The utility model is in the time that protected apron is subject to collision deformation, buffer stopper can play absorption energy, alleviate impact force action, between fixed head and bridge side bar, also leave certain spacing, make between whole fixed head and bridge side bar, also to there is certain buffering deformation space, when fixed head touches bridge side bar, obtain the support of side bar, buffer is unlikely and is knocked down, and supporting seat connects the non-perfect rigidity connected mode of employing, rectangle bolt hole about 2.5cm more than needed gap also after erection bolt, in the time that protected apron is subject to collision deformation, supporting seat can produce relative sliding motion, after the non-perfect rigidity opposing that subtracts energy and supporting seat through the buffering of buffer stopper, the strength being delivered on bridge side bar just diminishes, thereby reach the object of protection bridge, vehicle loss simultaneously also reduces greatly.
When the utility model is implemented, above protected apron is met the yellow black alternate reflecting marking of car face spraying, protected apron, limit for height, speed(-)limit sign are installed, and the ancillary facilities such as speed brake are set, contribute to point out driver to slow down and go slowly, avoid and mitigation, all helpful to vehicle, personnel, anticollision device, collision-prevention device and bridge.

The specific embodiment
Illustrate the utility model below in conjunction with accompanying drawing.
As shown in Fig. 1~4, a kind of bridge buffering anti-collision device, comprises protected apron 1, fixed head 2, buffer stopper 3, supporting seat 4, cross bar 5, small flange plate 6, large flange 7, bridge pier cap 8, bridge side bar 9.Buffer stopper 3 is arranged between protected apron 1 and fixed head 2 by bolt, between protected apron 1 and fixed head 2, be provided with 8~20 buffer stoppers 3, the about 300mm of spacing left and right between every two buffer stoppers, fixed head 2 is trapezium structure, fixed head 2 both sides are bolted on protected apron 1, on protected apron 1, be coated with yellow black alternate reflecting marking, its top is provided with limit for height, speed(-)limit sign, and supporting seat 4 is arranged on protected apron 1 both sides.
As shown in Figure 5, supporting seat 4 is made up of cross bar 5, small flange plate 6 and large flange 7, cross bar 5 one end are connected with small flange plate 6, the other end is connected with large flange 7, on small flange plate 6, be provided with rectangle bolt hole, and be connected with protected apron 1 by bolt, large flange 7 is bolted on bridge pier (platform) cap 8.
