Description

Novel flexible anticollision barrier
Technical field
The present invention relates to municipal guard bar technique fields, and in particular to a kind of novel flexible anticollision barrier.
Background technique
Safety protection facility of the highway anti-collision guardrail as highway side can be motor vehicle during highway driving Safety guarantee is provided.Highway barrier and other warning, prompt etc. safety devices the difference is that, guardrail is the bullet by itself Plastic deformation, friction, car body deformation etc. absorb impact energy to reduce the severity of accident, protect occupant, road The safety of road building and other outer things of road.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of novel flexible anticollision barriers, reduce shock and make to guardrail At destruction and damage.
In order to solve the above technical problems, the present invention adopts the following technical scheme that: novel flexible anticollision barrier, including column column Body, internal high strong spring, locking device, high-strength steel cord, bottom linker, middle part activity boss and bottom nozzle mounts;It is described Column cylinder, middle part activity boss and bottom nozzle mounts set gradually from top to bottom, and connected by high-strength steel cord;It is described The bottom of high-strength steel cord is fixed on bottom nozzle mounts, and top passes through middle part activity boss and protrudes into column cylinder and lock dress It sets and is fixedly connected;The locking device is slidably connected with the column cylinder;The high-strength steel cord is in place in locking Part between device and middle part activity boss is arranged internal high strong spring;The bottom nozzle mounts are located at the bottom and connect In fitting, fixed by pre-embedded bolt.
Further, balance weight is provided in the column cylinder;The balance weight is located at the lower part of column cylinder.
Further, the middle part activity boss is provided centrally with steel-cable channel;Middle part activity boss includes top Sphere and lower part cube.
Further, the periphery of the column cylinder is provided with anti-collision beam;The anti-collision beam passes through beam connection It is fixed on column cylinder.
Further, the section of the anti-collision beam is " bow " word structure.
Further, the column cylinder is hollow structure, and bottom opening, upright column cover cap is arranged in top.
Further, guide groove is opened up on the inside of the column cylinder, guide pad is set on locking device;Described leads Ball assembly is set on block.
Beneficial effects of the present invention: the present invention is combined into flexible steel using the elasticity of spring and the ductility of steel itself and protects Column greatly reduces shock to destruction caused by guardrail and damages.
Detailed description of the invention
It, below will be to needed in the embodiment in order to more clearly illustrate the technical solution in the embodiment of the present invention Attached drawing is simply introduced, it should be apparent that, the accompanying drawings in the following description is only some embodiments recorded in the present invention, for For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other Attached drawing.
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the status diagram that guardrail of the invention is hit.
Specific embodiment
Technical solution of the present invention will be clearly and completely described by specific embodiment below.
It as depicted in figs. 1 and 2, is novel flexible anticollision barrier of the invention, including upright column cover cap 1, anti-collision beam 2, vertical Column cylinder 3, internal high strong spring 4, crossbeam connector 5, locking device 6, high-strength steel cord 7, balance weight 8, bottom linker 9, Middle part activity boss 10 and bottom nozzle mounts 11.
Column cylinder 3, middle part activity boss 10 and bottom linker 9 of the invention is set gradually from top to bottom.The present invention Bottom linker 9 be hollow structure, be provided with bottom nozzle mounts 11 in the cavity of bottom linker 9, bottom nozzle mounts 11 Effect is fixed high-strength steel cord 7.Bottom linker 9 and bottom nozzle mounts 11 are fixed by pre-embedded bolt.Bottom of the invention The top of portion's connector 9 is provided with wirerope perforation, and middle part activity boss 10 is provided centrally with steel-cable channel.Middle part activity Boss 10 includes the sphere 101 on top and the cube 102 of lower part;The length of cube 102 and the wide outer diameter for being all larger than column cylinder 3. Column cylinder 3 is hollow cylinder, can be square tube or round tube.Upright column cover cap is arranged in the lower opening of column cylinder, top 1.The diameter of cube 102 is equal to the internal diameter of column cylinder 3, and sphere 101 is actively socketed on the bottom of column cylinder 3.
7 bottom of high-strength steel cord of the invention is fixed on bottom nozzle mounts 11, and top sequentially passes through on bottom linker 9 Wirerope perforation, the inside of column cylinder 3 is protruded into after the steel-cable channel in middle part activity boss 10, pushed up with column cylinder 3 Portion's locking device 6 is fixedly connected.Locking device 6 of the invention can be to be various forms of for fixing high tensile steel wire rope end portion Locking device.Locking device 6 is slidably connected with column cylinder 3, and locking device 6 can move up and down inside column cylinder 3.In order to The stability moved up and down is kept, guide groove can be opened up on the inside of column cylinder, guide pad is set on locking device 6.
Of the invention is arranged with internal high-strength bullet in part of the high-strength steel cord 7 between locking device 6 and sphere 101 Spring 4.Locking device 6 moves down the internal high strong spring 4 of compression, the locking device 6 under the rebound effect of internal high-strength spring 4 Move up reset.
The present invention carries out effective protection for the outer wall of column cylinder 3, and anti-collision beam is arranged in the outer wall of column cylinder 3 2.Anti-collision beam 2 can be square tube, round tube, rectangular tube etc..Anti-collision beam 2 is connect by crossbeam connector 5 with column cylinder 3, horizontal The both ends of beam connection 5 are connected by bolt respectively at column cylinder 3 and anti-collision beam 2.
Anti-collision beam 2 of the invention generally " bends " word structure, when anti-collision beam 2 is hit, the anticollision of " bow " type Crossbeam 2 is that deformation occurs, absorbs a part from extraneous kinetic energy, while column cylinder 3 is effectively protected.
When anti-collision upright post or crossbeam are by external collision, column cylinder 3 is because by crossbeam stretching or direct collision, column column Body 3 and middle part activity boss 10 will appear it is irregular topple over phenomenon, because column cylinder 3 and middle part activity boss 10 are loose joint, It is as shown in Figure 2 to tighten internal high strong spring 4(for built-in high-strength steel cord 7 when column is toppled over), at this time at internal high strong spring 4 In pressured state, the constraint that get rid of stress of internal high strong spring 4 must open, so that the column cylinder 3 toppled over has one A time positive trend, in order to guarantee that column cylinder 3 can return just, column cylinder 3 is internally provided with balance weight 8, and balance weight 8 is most The lower part of column cylinder is set well, and balance weight 8 is generally circular or rectangular.Mistake of the internal high strong spring 4 in one bullet of pressure It effectively absorbs in journey from extraneous kinetic energy, to reduce destruction and degree of injury.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to design of the invention It is defined with range, without departing from the design concept of the invention, ordinary engineering and technical personnel is to this hair in this field The all variations and modifications that bright technical solution is made should all fall into protection scope of the present invention, claimed skill of the invention Art content is all documented in technical requirements book.
