Abstract
Description
Technical Field
[0001] The utility model relates to the field of road facilities, in particular to a road deviation correction and energy absorption anti-collision guardrail. Background Technique
[0002] The guardrail mentioned here refers to an industrial guardrail for anti-collision. The guardrail is mainly used to protect the safety of vehicles and personnel on the road. The hollow rubber is an integrally formed rubber, produced in the factory according to a template, similar to tire rubber. During daily use, the road guardrail is easily impacted by vehicles. When a vehicle slightly impacts the guardrail, the outer rubber layer deforms and corrects the driving direction of the vehicle by rebounding, enabling the vehicle to return to normal driving, and the small hollow tube inside the column does not deform. When a vehicle impacts the guardrail too heavily, the small hollow tube inside the column is impacted and deformed to absorb energy, reducing the damage caused by the vehicle impact. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a road deviation correction and energy absorption anti-collision guardrail, which reduces the damage caused by vehicle impact through deviation correction and energy absorption.
[0004] In order to achieve the purpose of the utility model, the technical scheme adopted by the utility model is as follows:
[0005] The utility model discloses a road deviation correction and energy absorption anti-collision guardrail, which includes a protection frame, a base, an anti-collision guard cylinder main body and a bottom rod. The protection frame is in a reverse U-shaped structure. Bases are fixed at both ends of the protection frame. An anti-collision guard cylinder main body is installed between the protection frame and the bottom rod. The anti-collision guard cylinder main body includes a rubber sleeve, a large hollow tube, a small hollow tube and a column. The anti-collision guard cylinder main body presents a four-layer structure. The outermost layer is the rubber sleeve, the second layer is the large hollow tube, the third layer is the small hollow tube, and the innermost layer is the column. Fixing holes for fixing the anti-collision guard cylinder main body are opened on the inner sides of the protection frame and the bottom rod. The large hollow tube, the small hollow tube and the column are all fixed in the fixing holes.
[0006] The rubber sleeve is composed of elastic rubber sheets and presents a hollow shape.
[0007] A small hollow tube is wound around one circle between the large hollow tube and the column.
[0008] Both the protection frame and the bottom rod are coated with fluorescent paint.
[0009] The beneficial effects of the utility model are as follows:
[0010] The anti-collision guardrail structure for roads designed by the present utility model is novel and ingenious, which can achieve hierarchical deviation correction, reduce the damage caused by impact force, and has a low construction cost. When installing the anti-collision guardrail for roads on the road, the guardrail is placed on the road through the base to complete the installation of the guardrail. When a vehicle slightly impacts the guardrail, the outer rubber layer deforms and corrects the driving direction of the vehicle through rebound, making the vehicle return to normal driving, and the small hollow tube inside the column does not deform. When the vehicle impacts the guardrail too heavily, the small hollow tube inside the column is impacted and deformed to absorb energy, reducing the damage caused by the vehicle impact.

[0017] The present utility model will be further described below in conjunction with the drawings and embodiments:
[0018] Refer to Figures 1-5 .
[0019] The present utility model discloses an anti-collision guardrail for road deviation correction and energy absorption, which includes a protection frame 1, a base 2, a main body 3 of the anti-collision cylinder and a bottom rod 4. The protection frame 1 has a U-shaped structure. The two ends of the protection frame 1 are fixed with bases 1. An anti-collision cylinder main body 3 is installed between the protection frame 1 and the bottom rod 4. The anti-collision cylinder main body 3 includes a rubber sleeve 301, a large hollow tube 302, a small hollow tube 303 and a column 304. The anti-collision cylinder main body 3 presents a four-layer structure. The outermost layer is the rubber sleeve 301, the second layer is the large hollow tube 302, the third layer is the small hollow tube 303, and the innermost layer is the column 304. Fixing holes 401 for fixing the anti-collision cylinder main body 3 are provided inside the protection frame 1 and the bottom rod 4. The large hollow tube 302, the small hollow tube 303 and the column 304 are all fixed in the fixing holes 401.
[0020] The rubber sleeve 301 is composed of elastic rubber sheets. The rubber sleeve 301 presents a hollow shape, and the hollow design of the rubber sleeve can play a good buffering role.
[0021] A small hollow tube 303 is wound around between the large hollow tube 302 and the column 304. Through these three-layer designs, it can play a role in energy absorption and deviation correction when being hit.
[0022] Both the protection frame 1 and the bottom rod 4 are coated with fluorescent paint, which can play a guiding role at night.
[0023] Working principle:
[0024] When installing the anti-collision, grading, deviation-correcting and energy-absorbing guardrail for roads on the road, the guardrail is placed on the road through the base to complete the installation of the guardrail. When a vehicle slightly hits the guardrail, the outer rubber layer deforms and corrects the driving direction of the vehicle through rebound, so that the vehicle returns to normal driving, and the small hollow tube inside the column does not deform. When the vehicle hits the guardrail too hard, the small hollow tube inside the column is deformed by the impact to absorb energy and reduce the damage caused by the vehicle impact.
[0025] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are equally included in the patent protection scope of the present invention.
