[0003] Existing bridge guardrails, when in use, usually provide direct rigid protection when a vehicle collides, i.e., a rigid collision is performed to reduce vehicle speed. This setting is likely to increase injuries to passengers and may cause the guardrail to break directly, posing a risk of vehicle falling, making it less practical. In addition, the guardrail takes a long time to repair after a collision, and its economy and safety are also poor.

[0004] Therefore, in response to the above problems, a road bridge guardrail is proposed to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown, the utility model provides a technical solution:

[0024] A road bridge guardrail includes a guardrail body 1, which includes at least two guardrail bodies 1. The two guardrail bodies 1 are arranged parallel to each other on both sides or in the middle of the road along the length direction of the road bridge. A mounting assembly is detachably arranged on the guardrail body 1, a buffer assembly is arranged on the mounting assembly, and a guide protection assembly is arranged on the buffer assembly. The mounting assembly, the buffer assembly and the guide protection assembly are arranged in multiple groups corresponding to each other and are evenly arranged on the guardrail body 1, and the guide protection assembly is located on the side of the guardrail body 1 close to the road vehicle. The guide protection assembly includes a rotating drum 2, which is rotatably arranged on the buffer assembly, and the axis of the rotating drum 2 is perpendicular to the ground, which is used to guide the rotation and unload force.

[0025] In this embodiment, a card slot 3 is provided on the guardrail body 1, and the card slot 3 is a non-through dovetail groove. The mounting assembly includes a mounting block 4, and a card block 5 is provided on the mounting block 4 at one end close to the guardrail body 1. The card block 5 corresponds to the shape and size of the card slot 3, and the card block 5 can be clamped on the card slot 3, and is used to detachably connect the mounting block 4 and the guardrail body 1, so that after a collision, only the damaged part can be quickly replaced and repaired, thereby improving the economy of maintenance and the safety of maintenance personnel; in another embodiment, threaded holes can also be provided on the card block 5 and the card slot 3, and the card block 5 and the card slot 3 can be connected by connecting bolts to strengthen the connection between the card block 5 and the card slot 3, thereby improving stability and preventing damage to the device by others, thereby improving the stability of the device.

[0026] In this embodiment, a slide groove 6 is provided on the mounting block 4, the length direction of the slide groove 6 is perpendicular to the length direction of the guardrail body 1, and the slide groove 6 of the mounting block 4 connected to the upper guardrail body 1 can be set as a through groove, and the slide groove 6 of the mounting block 4 connected to the lower guardrail body 1 is set as a groove with a bottom, that is, a groove with an opening upward; the buffer assembly includes a slider 7 and an elastic member 8, the slider 7 is slidably set in the slide groove 6, the sliding direction of the slider 7 is perpendicular to the length direction of the road and the axis of the drum 2 at the same time, and the slider 7 in the slide groove 6 on the mounting block 4 on the lower side cooperates with the slide groove 6 is used to support the rotating drum 2. The elastic member 8 can be a spring. The spring is arranged in the chute 6 along the length direction of the chute 6. One end of the elastic member 8 is arranged on the slider 7, and the other end of the elastic member 8 is arranged in the chute 6 close to the guardrail body 1. When a collision occurs, the rotating drum 2 drives the slider 7 to compress the elastic member 8, so that the rotating drum 2 will not produce a direct hard collision with the guardrail body 1, and the energy of the guardrail body 1 will be buffered, protecting the guardrail body 1 from deformation within a certain limit. The degree of protection depends on the elastic potential energy of the elastic member 8, thereby improving the practicality of the device.

[0027] In another embodiment, the slide groove 6 of the mounting block 4 connected to the upper guardrail body 1 can also be set as a groove opening downward to protect the elastic member 8 from damage by wind and rain, thereby improving the service life and economy of the device.

[0028] In this embodiment, the rotating drum 2 includes a rotating rod 21 and a rubber tube 22. The rotating rod 21 can be rotatably set on the slider 7 through a bearing. The rubber tube 22 is coaxially sleeved on the outside of the rotating rod 21. The inside of the rubber tube 22 is hollow and is used to place the buffer material 9. The flexible properties of the rubber tube 22 can squeeze the internal buffer material 9 when the rotating drum 2 is hit to release the impact energy and reduce possible damage.

[0029] In this embodiment, the buffer material 9 can be liquid water, which is a common material and has good economic efficiency. In another embodiment, in order to avoid evaporation or leakage of liquid water during long-term use, the buffer material 9 can be fine sand or other fluid materials without daily loss, thereby extending the service life of the device, reducing maintenance, and improving economic efficiency.

[0030] In this embodiment, a plug 10 is further included. An extrusion hole 11 is opened on the rubber tube 22, and the plug 10 is set at the extrusion hole 11. The plug 10 covers the extrusion hole 11 tightly. After the rubber tube 22 is deformed to a certain extent, in order to prevent the buffer material 9 in the rubber tube 22 from squeezing the rubber tube 22 and bursting it, the plug 10 pops out to release the buffer material 9, thereby avoiding possible damage to the rubber tube 22, and having good economic efficiency. At the same time, the plug 10 can be connected to the rotating drum 2 by a connecting rope to avoid the plug 10 popping out and causing harm to others, thereby improving safety.

[0031] In this embodiment, connecting rods 12 are further included. The connecting rods 12 are evenly arranged on the guardrail body 1 and are used to connect the guardrail bodies 1 on the upper and lower sides, thereby improving the stability of the guardrail body 1.

[0032] Working principle: First, at least two guardrail bodies 1 are set up along the length direction of the road bridge, and the two guardrail bodies 1 are set parallel to each other on both sides or in the middle of the road without affecting the normal traffic of the road; then the mounting block 4 is installed on the guardrail body 1, and the slider 7 is set on the mounting block 4, and the slider 7 is connected to the inner side of the slide groove 6 on the mounting block 4 through the elastic member 8; then the rotating drum 2 is installed on the slider 7, so that the rotating rod 21 of the rotating drum 2 is rotatably set on the slider 7; the plug 10 of the rubber tube 22 is opened, the buffer material 9 is added to the rubber tube 22, and the plug 10 is covered; when the guardrail is collided, the rotating drum 2 rotates for bias guidance, and at the same time the rotating drum 2 drives the slider 7 to compress the elastic member 8 to buffer the energy of the collision on the guardrail body 1; the collision squeezes the rubber tube 22, so that the buffer material 9 rushes out of the rubber tube 22, releasing the impact energy and reducing the damage caused by the collision; during subsequent maintenance, only the mounting assembly, buffer assembly or guide protection assembly of the damaged part needs to be quickly replaced and can be continued to be used, which is more economical.
