Description

The equipped buffer device for collision of expressway guardrail

Technical field

The utility model is related to the buffer device for collision that a kind of expressway guardrail is equipped with.

Background technology

It is currently at the road traffic great development stage, 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 centrifugation force effect bump against expressway protective fence on the outside of road when, easily cause and turn over Vehicle, goes out the problems such as protective fence at a chain of collision, currently, expressway protective fence is mostly cement or metal material, elasticity it is poor and at Originally 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, a kind of we devise elasticity is higher, lower-cost expressway guardrail is equipped buffer device for collision.

Utility model content

The purpose of this utility model is to provide the crusherbull zone that a kind of elasticity is higher, lower-cost expressway guardrail is equipped Device.

The utility model technical solution used for the above purpose is：A kind of collision that expressway guardrail is equipped is slow Flushing device, including fixture, supporting rod, nylon rod inner core, the golden cartridge type rubber crust of rolling and sliding bearing, the fixture fixed clamp On the guardrail of expressway, the supporting rod is mounted on in-core in nylon rod, and the golden cartridge type rubber crust of the rolling is sleeved on nylon rod On inner core, the supporting rod, nylon rod inner core and the golden cartridge type rubber crust of rolling are commonly mounted on fixture, the sliding bearing peace 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 the rolling is inverted round stage structure.

A kind of equipped buffer device for collision of expressway guardrail of the utility model, simple in structure, weight is light, is readily disassembled Assembling, 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 be high Sliding friction when fast road vehicles collision becomes rolling friction, effectively plays buffer protection effect, and expressway guardrail is equipped to be touched It hits buffer unit and is internally provided with sliding bearing, further function as guiding role, surface is bright yellow, may also function as road and warns work With.

Specific implementation mode

As shown in Figures 1 to 5, the equipped buffer device for collision of expressway guardrail, 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, rolls 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 are the anti-skid chequer for increasing frictional force, supporting rod that T7 steel, structure is used to have screw thread similar to bolt, one end, play 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 Staple fiber is formed and be added, and is inverted round stage structure, surface is that bright yellow plays the role of warning, when being covered with point increase contact Frictional force and elastic buffer.

The equipped buffer device for collision of expressway guardrail by fixture fixed clamp on the guardrail of expressway, in Frequent Accidents Duan Jia great installs number, and outside is that inverted round stage structure rolls golden cartridge type rubber crust, 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 adds the fiber crops on 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；Sliding Bearing is standard component, is mounted on inside the buffer device for collision that expressway guardrail is equipped with, and is located at close to each one of top and bottom, When the equipped buffer device for collision of guardrail is collided in expressway, 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 equipped crusherbull zone of expressway guardrail can be also played in vehicle collision Device collides for vehicle or on a highway since the too fast sideways inclined of speed is slided to by centrifugation force effect on the outside of road The traffic problems such as expressway protective fence are bumped against, effective safeguard procedures are provided.
