Description

Technical Field

[0001] The utility model relates to the technical field of municipal highways, in particular to a municipal highway guardrail anti-collision device. Background Art

[0002] Municipal highway guardrails are facilities used to separate roads and protect the safety of pedestrians and vehicles. They are usually installed in urban roads, highways, bridges, tunnels, etc., and are of great significance for road driving.

[0003] Most of the existing railings are installed directly without adding some protective structures, which can easily lead to serious damage to the internal structure of the railing when a car collides with the railing, causing personnel to reinstall it, which is time-consuming and labor-intensive. In addition, the damaged railing will also affect the normal driving of the road. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a municipal highway guardrail anti-collision device.

[0005] The utility model is implemented by the following technical scheme: a municipal highway guardrail anti-collision device, comprising a base frame, a guardrail is inserted into the upper surface of the base frame, a protective component is fixedly connected to the outer surface of the guardrail, and both sides of the upper surface of the base frame are fixedly connected to connecting blocks;

[0006] The protection component includes an upper base, the lower surface of which is fixedly connected to an upper bearing, the interior of the upper bearing is fixedly connected to a shock-absorbing cylinder, the bottom of the shock-absorbing cylinder is fixedly connected to a lower bearing, the surface of the lower bearing is fixedly connected to a lower base, and the upper base and the lower base are fixedly connected to both sides of the middle of the outer surface of the railing.

[0007] Through the above technical solution, through the protective component, when encountering external force impact, since the surface of the shock-absorbing tube is relatively convex, the external force first hits the surface of the shock-absorbing tube. At this time, the shock-absorbing tube will rotate along the upper bearing and the lower bearing after being hit. The rotation can help the railing to disperse the impact force and reduce the damage to the railing structure. The transmission direction of the external force is changed by rotation, thereby achieving the effect of unloading force and shock reduction.

[0008] As a further improvement of the above solution, the top of the connecting support block is fixedly connected to a top plate, the top of the railing is inserted into the top plate, and the top of the railing is threadedly connected to a first nut.

[0009] Through the above technical solution, the top of the railing is fixed to the surface of the top plate by the first nut, which improves the stability of the railing installation and fixation, prevents the railing from being impacted by external force, causing the two ends to loosen and shift, and provides relatively firm protection for the top of the railing.

[0010] As a further improvement of the above solution, a mounting groove is provided in the middle of the front side of the base frame, and a reflective strip is fixedly connected inside the mounting groove.

[0011] Through the above technical solution, the reflective strips can reflect the light from the vehicle's headlights, making it easier for the driver to see the road conditions and the surrounding environment, improving the safety of driving at night. The reflective strips can also be used to warn the driver of dangerous sections, construction areas, accident scenes, etc. ahead, reminding the driver to slow down and drive carefully to ensure safety.

[0012] As a further improvement of the above solution, shock absorbing blocks are fixedly connected to both sides of the bottom of the base frame, and the bottom of the shock absorbing blocks is fixedly connected to a magnetic base.

[0013] Through the above technical solution, the magnetic base has strong fastness, which can ensure that the equipment or items will not fall off easily during the installation process, improve the stability of the overall device when placed, and the magnetic base can be quickly adsorbed and disassembled, which is convenient for users to install and use equipment or items in different locations, saving time and energy.

[0014] As a further improvement of the above solution, an extension plate is fixedly connected to one side of the magnetic base, and the bottom end of the railing is inserted into the interior of the extension plate.

[0015] Through the above technical solution, the bottom end of the railing is inserted into the inside of the extension plate, the bottom end of the railing is fixed for a second time, and the top and bottom ends of the railing are fixed at the same time, which can ensure that the railing will not easily loosen or shift when impacted.

[0016] As a further improvement of the above solution, lateral support rods are fixedly connected to both sides of the upper surface of the extension plate, and semicircular clamps are fixedly connected to the top ends of the lateral support rods.

[0017] Through the above technical solution, the lateral support rod can provide lateral support force, and at the same time drive the semicircular clamp to clamp and fix the bottom end of the railing, thereby preventing the railing from being subjected to lateral support force and being prone to tilting.

[0018] As a further improvement of the above solution, both sides of the semicircular clamp are fixedly connected with raised plates, and the internal threads of the raised plates are connected with limiting bolts.

[0019] Through the above technical solution, the two sides of the semicircular clamp are fixed by limiting bolts, which can improve the stability of the semicircular clamp when it is fixed, and at the same time facilitate personnel to disassemble and install it, and the operation is simple and convenient.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model provides a protective component. When encountering an external force impact, the external force first impacts the surface of the shock-absorbing cylinder because the surface of the shock-absorbing cylinder is relatively convex. The shock-absorbing cylinder rotates along the upper bearing and the lower bearing after the impact. The rotation can help the railing to disperse the impact force and reduce damage to the railing structure. The transmission direction of the external force is changed by rotation, thereby achieving the effect of unloading and shock reduction. At the same time, the top end of the railing is fixed to the surface of the top plate by a first nut, and the lateral support rod drives the semicircular clamp to clamp the bottom end of the railing, thereby improving the stability of the railing during installation and avoiding the phenomenon that the two ends of the railing are loosened and shifted due to the impact of external force.
