Abstract
The invention discloses a safety height limiting rod. The safety height limiting rod is characterized by comprising two rigid stand columns (1) and two elastic cross beams, wherein each elastic cross beam is connected with the top of each rigid stand column (1) through a flange (2) and a sleeve (7); the main bodies of the elastic cross beams consist of strong springs (3) and are externally wrapped by rubber sleeves (4); the other ends of the elastic cross beams are provided with magnets (5-1, 5-2). After the height limiting rod is collided, the cross beam part of the height limiting rod deforms elastically under the action of impact force, and the maximum deformation angle can reach 90 degrees, so that a part of impact energy is absorbed to reduce the collision force stressed by vehicles and drivers and passengers thereof during collision of the vehicles and the height limiting rod, and besides the cross beams of the height limiting rod are not damaged after the elastic deformation, are convenient to maintain, can be repeatedly used and are safe to use and low in cost.
Description
Technical field
The present invention relates to road safety facility technology field, particularly, relate to a kind of safety height-limiting bar.
Background technology
In daily road traffic, often need to limit by height limiter the traffic safety that the height of traffick or loading height ensure highway, ring road, culvert, bridge etc.Along with the continuous increase of vehicle fleet size, original height-limiting bar can not meet the demands, lance accident is original more, because height-limiting bar intensity is too large, height-limiting bar that is that cause collapses and the accident of vehicle damage constantly increases, due to height-limiting bar fracture, ascendant trend is also become to other vehicles and the phenomenon that pedestrian damages, result in great property and the loss of personnel.
Summary of the invention
The technical problem to be solved in the present invention is, during for height-limiting bar in road traffic and vehicle rigid collision, damaged vehicle and the serious phenomenon of injury to personnel, provide a kind of safety height-limiting bar.
The technical solution used in the present invention comprises:
A kind of safety height-limiting bar, is characterized in that, comprise two rigid posts 1 and two there is flexible crossbeam, wherein, every root Spring beams is connected with the top of sleeve 7 with rigid posts 1 by flange 2; The main body of described Spring beams is made up of brute spring 3; The body exterior of described Spring beams is wrapped up by rubber sleeve 4; The other end of described Spring beams is provided with magnet 5-1 and 5-2.
Particularly, the main body of every root rigid posts 1 is the rectangular structure of hollow, and rectangular structure is provided with circular hole 8 near the position at top, and the center line of circular hole 8 is consistent with the center line of sleeve 7, and sleeve 7 and rigid posts 1 are rigidly connected; Every root rigid posts 1 is connected with brute spring 3 respectively by flange 2.
Particularly, the main body of every root rigid posts 1 is the rectangular structure of hollow, and the main part of Spring beams is brute spring 3, and brute spring 3 passes the top of rigid posts 1 by sleeve 7 and circular hole 8, is connected with rigid posts 1 by flange 2.
Particularly, the main part of Spring beams is brute spring 3, and profile is cylindrical, and one end of brute spring 3 and magnet 5-1 and magnet 5-2 are rigidly connected, and the outside of brute spring 3 is wrapped up by rubber sleeve 4, and wherein one end is connected with sleeve 7 by rivet 6.
Particularly, described flange 2 is rigidly connected with brute spring 3, and flange 2 is connected with rigid posts 1 by bolt 9.
The present invention's advantage is compared with prior art:
1. effectively can reduce the injury of clashing into and vehicle itself being caused, due to the deformability characteristics of Spring beams, can bend to the direction of clashing into after Spring beams is clashed into, height-limiting bar can being avoided to cause accident vehicle when being subject to external impact load badly damaged, even fracture occurring and secondary injury is caused to other vehicles or pedestrians.
2., after clashing into, due to the deformability characteristics of Spring beams, Spring beams can rupture or damage to the direction of clashing in bending and unlikely generation, and be not easy to damage, be convenient to safeguard, use cost is cheap.

Detailed description of the invention
The invention discloses a kind of safety height-limiting bar, after height-limiting bar is hit, can there is elastic deformation in the header portion of height-limiting bar under impact force action, maximum distortion angle can reach 90 °, on the one hand absorb part impact energy, reduce vehicle and the impact suffered by driver and conductor thereof when vehicle and height-limiting bar collide; In addition, can not damage after height-limiting bar crossbeam generation elastic deformation, and easy to maintenance, can reuse, use safety, cost is low.
Composition graphs 1, Fig. 2 and Fig. 3, described safety height-limiting bar comprise two rigid posts 1 and two there is flexible crossbeam, wherein, every root Spring beams is connected with the top of sleeve 7 with rigid posts 1 by flange 2; The main body of described Spring beams is made up of brute spring 3; The body exterior of described Spring beams is wrapped up by rubber sleeve 4; The other end of described Spring beams is provided with magnet 5-1 and 5-2.
In the preferred embodiment, safety height-limiting bar comprise two rigid posts 1 and two there is flexible crossbeam, wherein, every root Spring beams is connected with the top of sleeve 7 with rigid posts 1 by flange 2; The main body of described Spring beams is made up of brute spring 3; The body exterior of described Spring beams is wrapped up by rubber sleeve 4; The other end of described Spring beams is provided with magnet 5-1 and 5-2.Under normal circumstances, two Spring beams are attached together by magnet 5-1 and magnet 5-2, form one whole crossbeam, after this Spring beams is subject to Overheight Vehicles shock, because Spring beams main body is brute spring 3, every root main body of cross-beam can bend towards crash direction, elastic deformation occurs, and now, height-limiting bar opens, avoid vehicle to be subject to rigid impact head-on, cause the tragedy of car crash; After vehicle is removed, Spring beams returns to normal condition again due to the effect of brute spring 3, can continue to use, simple and easy.
After this Spring beams clashes into, vehicle can be absorbed to the shock loading of crossbeam by the flexural deformation of self, avoid self and rupture, thus can avoid causing secondary injury to other vehicles and pedestrian.
The main part of Spring beams is columniform brute spring 3 structure, and its one end by circular hole 8 and sleeve 7, then is connected with rigid posts 1 by flange 2; Sleeve 7 can support brute spring 3, avoid brute spring 3 because of self gravitation effect sagging.
In addition, above-mentioned flange arrangement and bolt are the known technology of those skilled in the art.Wherein, flange is disk (or other shapes) structure, and it is provided with several through holes equably, for flange 2 and rigid posts 1 being coupled together by bolt.
At this, it should be noted that, the content do not described in detail in this manual, be that those skilled in the art can be realized by the description in this manual and prior art, therefore, do not repeat.
The foregoing is only the preferred embodiments of the present invention, be not used for limiting the scope of the invention.For a person skilled in the art, under the prerequisite not paying creative work, can make some amendments and replacement to the present invention, all such modifications and replacement all should be encompassed within protection scope of the present invention.
