Description

Be used for highway buffer stop

Technical Field

The utility model relates to a be used for highway buffer stop, especially a simple structure, the expense is low, is suitable for highway and highway median and roadside protecting band device.

Background

With the progress of the times, the development of roads in China also realizes the leap forward, which not only depends on the basic national conditions of China in modern times, but also explains the progress and innovation of civil engineering and public works in China.

The highway in China is approximately 400 kilometers by the end of 2010, and the road is increased by 47 times compared with the road construction period of 8.07 kilometers. Wherein, the highway mileage reaches 60302 kilometers, and 54216 kilometers are the first-class kilometers, and national highway network is built by 48896 kilometers, accounting for 56.5% of the planned mileage. Wherein, the national road trunk line with five longitudinal lines and seven transverse lines is constructed to be full-line through. The construction of rural highways is also a bright spot, the scheme of village traffic proposed by the center is also implemented, and the traffic rate of the village and the town reaches 100%.

The annual sales of the automobiles in China are the first in the world for 8 years, and at present, the automobiles in China keep 2 hundred million vehicles, the quantity of the automobiles in China accounts for 20 percent of the whole world, and the quantity of the automobiles in China accounts for 30 percent of the whole world. At present, thousands of automobiles in China hold 140 automobiles. Traffic accidents occur frequently. Especially, when the protection is lacked or the traditional rigid protection device is adopted, the vehicle is out of control or rushes out of the road, or the guardrail is collided to cause serious casualty, therefore, the novel anti-collision guardrail device is continued to ensure the safety of the vehicle and personnel.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that one kind is used for highway buffer stop, has avoided traditional highway protection to adopt the rigidity protection, easily causes the condition of vehicle casualties and the drawback that the preparation is wasted time and energy etc to this equipment simple structure, the expense is low, is suitable for highway and highway median and roadside protecting band.

In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the utility model provides a be used for highway buffer stop, includes the concrete base, fixes the stand on the base, the cover can the part rotatory anticollision bucket on the stand, sets up the rotatory recess in left side and the rotatory recess in right side on the anticollision bucket, is equipped with the middlings sand in the anticollision bucket, and high-strength steel strand wires link to each other with the stand.

The concrete base is fixed on the upright post on the base.

The anti-collision barrel 2 is provided with the left rotating groove 5 and the right rotating groove 6, so that the deflection angle of the anti-collision barrel 2 is not less than 45 degrees.

The utility model has the advantages that: the rigid protection adopted by the traditional highway protection is avoided, the condition of vehicle casualties is easily caused, and the defects of time and labor waste and the like in manufacturing are overcome, and the equipment is simple in structure, low in cost and suitable for highway, expressway isolation belts and roadside protection belts.

Drawings

Fig. 1 is a schematic structural view of the road anti-collision device of the present invention.

Detailed Description

The invention will be described in further detail with reference to the following drawings and embodiments:

as shown in fig. 1, the utility model discloses a be used for highway buffer stop, including concrete base 7, fix stand 1 on concrete base 7, the cover can partial rotation's on

stand

2, 2 surfaces of anticollision bucket set up left side rotary groove 5 and right side rotary groove 6, and the coarse sand 3 in the 2 intussuseptions of anticollision bucket, and high-strength steel strand wires 4 link to each other with stand 1. The utility model discloses avoided traditional highway protection to adopt the rigidity protection, easily caused the condition of vehicle casualties and the drawback that the preparation is wasted time and energy etc to this equipment structure is simple, and the expense is low, is suitable for highway and highway median and roadside protecting band.

The anti-collision barrel 2 is provided with the left rotating groove 5 and the right rotating groove 6, so that the anti-collision barrel 2 can deflect at an angle not smaller than 45 degrees when being impacted by a vehicle, and the effect of reducing impact energy is achieved.

The anti-collision barrel 2 is internally provided with the medium coarse sand 3, the upright post 1 is surrounded, when the anti-collision barrel is impacted by a vehicle, rigid impact is avoided, a buffering effect is achieved, and the safety of the vehicle and personnel is further protected.

The high-strength steel strand 4 belongs to a high-strength flexible structure, so that a collided vehicle is buffered, and the rigid collision is avoided, so that the vehicle and the casualties are avoided.

The above-mentioned embodiments are only used for illustrating the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, the scope of the present invention should not be limited by the embodiment, that is, all equivalent changes or modifications made by the spirit of the present invention should still fall within the scope of the present invention.
