[0002] Municipal refers to the management activities and processes of various administrative affairs and social public affairs within the jurisdiction of a city. Road anti-collision guardrails are the most important traffic infrastructure, usually made of common steel materials such as round steel pipes, square steel pipes or profiled steel plates. The columns of the anti-collision guardrails are fixed to the ground through expansion bolts, usually installed on both sides of the road passage. The anti-collision guardrails can effectively reduce the degree of accident collision.

[0003] When the existing anti-collision guardrails are actually impacted by vehicles, the anti-collision effect is poor. When the vehicle impacts the guardrail, it may not be effectively buffered, and it is easy to break through the guardrail, thus triggering traffic accidents such as vehicle rollover and running off the road, with high danger.

[0004] In view of the above problems, the utility model proposes a road anti-collision guardrail for municipal design. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , in order to solve the problem that the existing anti-collision guardrail has a poor anti-collision effect when actually impacted by a vehicle, the vehicle may not be effectively buffered when hitting the guardrail, and it is easy to break through the guardrail, thereby triggering traffic accidents, such as vehicle rollover, running off the road, etc., with high danger, the following preferred technical solutions are provided:

[0022] A road anti-collision guardrail for municipal design, including a guardrail main body 1. A plurality of connecting rods 2 are fixedly connected to the lower end of the guardrail main body 1. An installation disc 3 is arranged at the lower end of each group of connecting rods 2. An installation sleeve 4 is arranged at the upper end of the installation disc 3. A concave installation block 5 is installed on the inner bottom plate of the cavity of the installation sleeve 4. The inner wall of the concave installation block 5 is movably connected to the connecting rod 2. An elastic column 6 is fixedly connected to the outer wall at the connection between the connecting rod 2 and the concave installation block 5. Buffer components 7 are arranged on both sides of the connecting rod 2. The elastic column 6 is inclined, and the lower end of the elastic column 6 is fixedly connected to the inner wall of the concave installation block 5.

[0023] The buffer component 7 includes a buffer block 71 that fits the connecting rod 2. An inner rod main body 72 is fixedly connected to the inner wall of the buffer block 71. The buffer component 7 further includes a moving groove 73 opened on the inner wall of the installation sleeve 4. The inner wall of the moving groove 73 is slidably connected to the inner rod main body 72. A buffer spring 74 is sleeved on the outer wall of the inner rod main body 72. One end of the buffer spring 74 is fixedly connected to the buffer block 71, and the other end thereof is fixedly connected to the inner wall of the installation sleeve 4.

[0024] A reinforcement component 8 is arranged at the edge of the installation disc 3. The reinforcement component 8 includes a reinforcement rod 81 that penetrates the installation disc 3. An installation channel 82 that penetrates the outer wall is opened inside the reinforcement rod 81. A middle partition block 83 is fixedly connected to the inner wall of the installation channel 82. Outer support rods 84 are arranged on both sides of the middle partition block 83. The end of the outer support rod 84 away from the middle partition block 83 is fixedly connected to a reinforcement block 85. An elastic element 86 is fixedly connected between the outer support rod 84 and the middle partition block 83. When the elastic element 86 is in a relaxed state, the reinforcement block 85 protrudes from the opening of the installation channel 82.

[0025] Specifically, after the guardrail main body 1 and the connecting rod 2 are impacted, the connecting rod 2 will tilt on the inner wall of the concave mounting block 5, thereby squeezing the buffer block 71. The buffer block 71 is compressed and deformed, and its outer wall sinks inward, driving the inner rod main body 72 to move into the cavity of the movable groove 73, thereby squeezing the buffer spring 74. Through the action of the buffer spring 74 and the cooperation of the elastic force column 6, the impact force can be greatly buffered, improving safety. This solves the problem that the existing anti-collision guardrail has a poor anti-collision effect when actually impacted by a vehicle. When the vehicle impacts the guardrail, it may not be effectively buffered, easily break through the guardrail, and then trigger traffic accidents such as vehicle rollover and running off the road, with high danger.

[0026] The reinforcing rod 81 passes through the mounting plate 3 and inserts into the soil. At this time, the reinforcing block 85 will be compressed to drive the outer support rod 84 to cooperate with the middle partition block 83 to squeeze the elastic element 86. After the elastic element 86 is compressed, it will give a reaction force to the outer support rod 84, causing the reinforcing block 85 to expand outward, thereby increasing the overall friction force of the reinforcing block 85 and improving the overall installation stability.

[0027] To sum up: after the guardrail main body 1 and the connecting rod 2 are impacted, the connecting rod 2 will tilt on the inner wall of the concave mounting block 5, thereby squeezing the buffer block 71. The buffer block 71 is compressed and deformed, and its outer wall sinks inward, driving the inner rod main body 72 to move into the cavity of the movable groove 73, thereby squeezing the buffer spring 74. Through the action of the buffer spring 74 and the cooperation of the elastic force column 6, the impact force can be greatly buffered, improving safety. The reinforcing rod 81 passes through the mounting plate 3 and inserts into the soil. At this time, the reinforcing block 85 will be compressed to drive the outer support rod 84 to cooperate with the middle partition block 83 to squeeze the elastic element 86. After the elastic element 86 is compressed, it will give a reaction force to the outer support rod 84, causing the reinforcing block 85 to expand outward, thereby increasing the overall friction force of the reinforcing block 85 and improving the overall installation stability.
