Description

Connecting assembly of anti-collision road rotary guardrail and rotary guardrail

Technical Field

The utility model belongs to the technical field of road traffic equipment, concretely relates to anticollision road rotary guardrail's coupling assembling and rotary guardrail.

Background

The urban traffic environment of China is more complex and various than other countries, the traffic flow mixing phenomenon is particularly prominent, the traffic flow mixing phenomenon is mainly represented as the mixed running of right-turning vehicles, non-motor vehicles and pedestrians, the phenomenon mostly appears at the intersection of urban roads, and the phenomenon is specifically reflected as two types of conflicts: the first type of conflict is the conflict between the right-turning motor vehicles and the side pedestrians, and the second type of conflict is the conflict between the right-turning motor vehicles and the same-direction street-crossing pedestrians. The urban road intersections are provided with signal lamps for separating traffic flows, reducing conflict points and improving the safety of the intersections. However, in China, most of right-turning motor vehicles at intersections are not controlled by signal lamps, and conflict with pedestrians cannot be avoided. Although the right-turning motor vehicles need to give way to pedestrians, in actual life, the right-turning motor vehicles frequently rush to the road, so that the passing of the pedestrians is delayed and the right-turning motor vehicles stay on a pedestrian crosswalk, the safety of the pedestrians is endangered, the passing of the motor vehicles is also blocked, and particularly in a time period with low road flow, the speed of the motor vehicles is high, and the safety of the pedestrians is endangered due to the fact that the right-turning motor vehicles are not timely avoided and collide or scratch with the pedestrians.

The safety island is a safety device installed on a zebra crossing, the length of the safety island is equivalent to that of the zebra crossing, two ends of the safety island are respectively provided with a 'reflecting warning pile', and the safety island can emit light under the shining of a car lamp at night to remind a driver of avoiding. The safety island is set up to enable people to form a habit of crossing streets for the second time, namely, the people arrive at the safety island of the pedestrian in the center of the road at the first green light time, and the people walk the rest of the road after the green light is turned on for the second time.

To solve the above problem, chinese patent CN201820162098.4 discloses an assembly and a security island having the same. The assembly includes: a circular tube upright post, on which a chassis is arranged; and the elastic rotating body is sleeved on the circular tube upright post, and the lower end surface of the elastic rotating body is abutted against the chassis. The assembly consists of a circular tube upright post and an elastic rotating body, when an automobile impacts the elastic rotating body, the impact force of the automobile is effectively absorbed by the elastic rotating body and reduced, the automobile is effectively prevented from rushing into a facing lane to collide or flying out of the lane, and the automobile is kept to run on a correct lane. The safety island is fixed on the ground by adopting the mode that the stand columns are fixed on the ground, and for some traffic intersections, the safety island needs to be flexibly arranged.

Detailed Description

The detailed description and exemplary embodiments of the invention may be better understood when read in conjunction with the following drawings, where the elements and features of the invention are identified by reference numerals.

As shown in fig. 1 to 3, the anti-collision road rotation fence of the present embodiment includes a connection assembly and an elastic rotator 30, wherein the connection assembly includes a base 10 and a pillar 20. When a vehicle impacts the guardrail, in order to avoid rigid collision, the upright post 20 is rotatably sleeved with an elastic rotating body 30. In some embodiments, the elastic rotating body 30 is made of polyurethane foam, for example, as disclosed in 201710519425.7, a reflective layer integrated with the elastic rotating body 30 is compounded on the surface of the elastic rotating body 30, so as to play a certain reflective warning role, and meanwhile, the reflective warning role also conforms to the relevant regulations of the national road traffic law. The compound mode of the reflective layer can be painting, penetrating, sputtering, etc., and is determined according to the selected material, and the technology is the existing public technology at present and is not described herein again. Has better elastic deformation and can absorb the impact force of the vehicle.

As can be seen from fig. 1, the base 10 is cylindrical and is provided with at least one pair of clamping rods 11, and the clamping rods 11 can be located at the outer side or the inner side; the upright post 20 is provided with an inner cavity 21 capable of being sleeved with the base 10, a stop ring 22 is arranged on the body of the upright post 20, a bayonet 23 is formed at the lower end of the body and matched with the clamping rod 11, and the upright post 20 is positioned and fixed through the clamping rod 11; the bayonet 23 comprises an inlet 231, a turning cavity 232 and a containing cavity 233 which are sequentially connected, the width of the inlet 231 and the width of the turning cavity 232 are larger than the width or the diameter of the clamping rod 11, and the width of the containing cavity 233 is equal to or slightly smaller than the width or the diameter of the clamping rod 11.

During the use, with base 10 pre-buried to the road bed in, and the upper end flushes with the road surface, under general conditions, kelly 11 is located the inside of base 10, just to kelly 11 and rotation with the bayonet socket of stand 20, by the clearance fit who holds chamber 233 and kelly 11, has improved the steadiness.

In some embodiments, it can be seen that the two ends of the turning cavity 232 extend horizontally to join the inlet cavity 231 and the accommodating cavity 233. Further, the center line of the inlet chamber 231 and the center line of the receiving chamber 233 are located in the vertical direction, so that the quick butt joint during the plugging process is facilitated, and the resistance is reduced as little as possible. The centerline of the inlet chamber 231 is in the same vertical plane as the centerline of the upright 20. The upper end contour line that holds chamber 233 matches with the up end contour line of kelly 11 for kelly 11 forms the face contact with holding chamber 233, and increase frictional force further improves the steadiness.

The elastic rotating body 30 is sleeved on the upright post 20 and is positioned and stopped by the stop ring 22, and the stop ring 22 is integrated with the upright post 20; or the stop collar 22 is welded to the upright 20. The material of the stop ring 22 is the same as or different from that of the upright column 20, for example, 45# steel is used for both the stop ring 22 and the upright column 20, or 45# steel is used for the stop ring 22, and Q235 material is used for the upright column 20.

Further, an end cover 24 is provided on the upright post 20, and the end cover 24 is fixed on the top of the upright post 20 by screws, or the end cover 24 and the upright post 20 are integrated. The end cover 24 comprises a shell, a solar cell panel, a storage battery, a chip and a diode, wherein the solar cell panel is connected with the storage battery, and the storage battery is electrically connected with the chip and the diode. On one hand, the end cover 24 seals the top of the upright post 20, so that the corrosion speed of the upright post 20 can be reduced; on the other hand, the end cover 24 can emit light to play a certain warning role.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
