Description
Technical field
The present invention relates to the buffer device for collision that a kind of expressway guardrail is equipped with.
Background technology
The road traffic great development stage is currently at, with the sustained economic development in China, people, vehicle, road remain on height
Fast momentum of development, accident incidents frequently occur, especially on the faster expressway of speed, when vehicle occurs on a highway
Collision or due to the too fast sideways inclined of speed slided to by centrifugal force effect bump against expressway protective fence on the outside of road when, easily cause and turn over
Vehicle, is gone out the problems such as protective fence at a chain of collision, and at present, expressway protective fence is mostly cement or metal material, elasticity it is poor and into
Originally it is higher that cushioning effect cannot be effectively provided or even secondary injury can be caused to vehicle, more serious traffic accident is caused, in view of before
The problem of described, a kind of we devise elasticity is higher, lower-cost expressway guardrail is equipped with buffer device for collision.
Invention content
The object of the present invention is to provide the crusherbull zone dresses that a kind of elasticity is higher, lower-cost expressway guardrail is equipped with
It puts.
Present invention technical solution used for the above purpose is：The crusherbull zone dress that a kind of expressway guardrail is equipped with
It puts, including fixture, supporting rod, nylon rod inner core, the golden cartridge type rubber crust of rolling and sliding bearing, the fixture fixed clamp is in height
On fast road guardrail, the supporting rod is mounted on in-core in nylon rod, and the golden cartridge type rubber crust of rolling is sleeved on nylon rod inner core
On, the supporting rod, nylon rod inner core and the golden cartridge type rubber crust of rolling are commonly mounted on fixture, and the sliding bearing is mounted on
Each one of upper and lower part between supporting rod and nylon rod core.
The fixture is made of two parts, and left end is square, and right end is the bending of 60 ° of bending angle.
The left end of the fixture and right end lower part are equipped with the anti-skid chequer for increasing frictional force.
One end of the supporting rod is equipped with screw thread.
The golden cartridge type rubber crust of rolling is inverted round stage structure.
The buffer device for collision that a kind of expressway guardrail of the present invention is equipped with, simple in structure, weight is light, is readily disassembled group
Dress, is suitable for different kinds of roads, of low cost using isoprene rubber crust, secondary can also be turned waste into wealth using old tire, will at a high speed
Sliding friction when road vehicles collide becomes rolling friction, effectively plays buffer protection effect, the collision that expressway guardrail is equipped with
Buffer unit is internally provided with sliding bearing, further functions as guiding role, and surface is bright yellow, may also function as road and warns work
With.

Specific embodiment
As shown in Figures 1 to 5, the buffer device for collision that expressway guardrail is equipped with, including fixture 1, supporting rod 2, nylon rod
Inner core 3, the golden cartridge type rubber crust 4 of rolling and sliding bearing, for 1 fixed clamp of fixture on the guardrail of expressway, supporting rod 2 is mounted on Buddhist nun
In imperial stick inner core 3, roll golden cartridge type rubber crust 4 and be sleeved on nylon rod inner core 3, supporting rod 2, nylon rod inner core 3 and the golden cylinder of rolling
Formula rubber crust 4 is commonly mounted on fixture, and the upper and lower part that sliding bearing is mounted between supporting rod and nylon rod core is each
One, fixture uses T7 steel, is made of two parts, and left end is square, and right end bending angle is 60 degree, and both ends lower part is all
There is the anti-skid chequer for increasing frictional force, supporting rod uses T7 steel, and structure has screw thread similar to bolt, one end, plays the role of revolving support,
Nylon rod inner core is made of nylon rod, and there is through-hole in centre, for installing supporting rod, rolls golden cartridge type rubber crust by isoprene rubber system
It forms and adds in staple fiber, and be inverted round stage structure, surface plays the role of warning for bright yellow, when being covered with point increase contact
Frictional force and elastic buffer.
The buffer device for collision that expressway guardrail is equipped with by fixture fixed clamp on the guardrail of expressway, in Frequent Accidents
Duan Jia great installs number, and golden cartridge type rubber crust is rolled in outside for inverted round stage structure, the golden cartridge type rubber crust of inverted round stage structure rolling by
Isoprene rubber, which is made, higher rigidity and elasticity, and when being collided, plastic deformation is small, and can using inverted round stage structure
The power rolled to the reaction force and the golden cylinder of promotion rolling on ground is provided, a component can prevent from overturning, and a component is plus surface
Sliding friction when colliding can be become rolling friction protection vehicle by point, due to adding staple fiber, thus rolling resistance compared with
It is low, rolling frictional resistance is further reduced, reduction speed can be played significantly, improves safe effect, surface is designed as bright Huang
Color may also function as the effect of warning；Nylon rod inner core is made of nylon rod, and good toughness, tear resistance is strong, oil resistant, antidetonation, stretches, bending
Intensity is good, and larger reaction force can be provided when being collided and wearability is good, of low cost, can mould Dai Gang；It slides
Bearing is standard component, inside the buffer device for collision that guardrail is equipped with mounted on expressway, positioned at close to each one of top and bottom,
When the buffer device for collision that guardrail is equipped in expressway is collided, with one same-action of component, provides rolling for the golden cylinder of rolling and be oriented to
Power strengthens rolling friction；The golden cartridge type rubber crust of they sup-port inverted round stage structure rolling and nylon rod inner core, due to the use of
T7 steel toughness is preferable, therefore, certain cushioning effect, the crusherbull zone that expressway guardrail is equipped with can be also played in vehicle collision
Device for vehicle collides or is slided on the outside of road since the too fast sideways inclined of speed is acted on by centrifugal force on a highway
The traffic problems such as expressway protective fence are bumped against, provide effective safeguard procedures.
