Description

A collision avoidance device for road engineering Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically to an anti-collision device for road engineering. Background Technology

[0002] Currently, as a road safety protection measure, guardrails are used on both sides and in the middle of highways and expressways in my country and other countries. Bridges and tunnels generally use cement stepped protective piers, and handrails are usually added to bridges, which have a certain protective effect on out-of-control vehicles traveling at low speeds.

[0003] Patent CN219808306U discloses a municipal road guardrail. The guardrail, composed of horizontal bars, multiple vertical bars, a horizontal tube, and two vertical tubes, can divide municipal roads. Two legs allow the guardrail to be installed at appropriate locations on the road. Two lifting and moving mechanisms facilitate the movement of the guardrail without affecting its installation, thus simplifying installation and disassembly. A horizontal and vertical transmission mechanism drives two screws to rotate. Multiple casters are housed in clearance grooves. The screws rotate on the inner wall of the threaded sleeve, causing the casters to move up and down. Multiple limiting grooves and blocks limit the movement of the threaded sleeve. A transmission rod and multiple bevel gears drive the two screws to rotate, and a worm gear and worm wheel drive the transmission rod to rotate.

[0004] However, the above technology still has the following problems:

[0005] Composed of horizontal bars, multiple vertical bars, horizontal tubes, and two vertical tubes, the structure is simple. However, when subjected to external impact loads, its own shock absorption effect is often insufficient to cope with high-load impacts, resulting in the guardrail not being able to effectively reduce the injury to occupants. Rigid guardrails are prone to causing serious damage to vehicles during collisions, and may even trigger secondary accidents (such as vehicle rollovers). Summary of the Invention

[0006] In view of the shortcomings of the existing technology, this utility model provides a collision avoidance device for road engineering, which can play a role in buffering and steering.

[0007] This utility model provides the following technical solution: a collision avoidance device for road engineering, comprising two bases, each base having a support rod fixedly connected to it, and two mutually symmetrical fixed seats connected between the two support rods, with a reinforcing plate fixedly connected between the two mutually symmetrical fixed seats, the fixed seats having a plurality of threaded holes, and a plurality of connecting seats detachably connected to the fixed seats, the connecting seats having a plurality of round holes matching the threaded holes, and a buffer mechanism rotatably connected to the connecting seats, the fixed seats and the connecting seats being fixed together by a plurality of hexagonal bolts.

[0008] Furthermore, the support rod has a second circular hole that penetrates the lower surface of the base.

[0009] Furthermore, the fixing base includes an L-shaped support plate fixedly connected between two support rods. The L-shaped support plate has several equally spaced slots, and threaded holes are located on both sides of the slots.

[0010] Furthermore, the connecting seat includes a locking block that is adapted to the two locking slots. Side plates are fixedly connected to both sides of the two locking blocks, and a round hole is opened on the side plate. A rotating shaft is fixedly connected between the two locking blocks.

[0011] Furthermore, the buffer mechanism includes a roller rotatably connected to a rotating shaft, with a buffer pad installed on the outer wall of the roller, and reflective markings provided on the buffer pad.

[0012] Furthermore, the inside of the roller is provided with a cavity, and a reinforcing rod is fixedly connected to the inner wall of the cavity.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of road engineering anti-collision device, through the design of a buffer mechanism, can buffer and reduce shock when a vehicle hits the guardrail, reducing damage to the vehicle and people. At the same time, after the buffer mechanism is installed, the vehicle's driving direction can be adjusted so that it moves along the surface of the buffer mechanism, reducing the probability of secondary accidents. Furthermore, this device can be installed on one side of the road or offset in the median of two-way lanes. It is simple, quick and convenient to operate. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please refer to Figures 1 to 3. A road engineering anti-collision device includes two bases 1, each with a support rod 2 fixedly connected to it. The two support rods 2 are connected together by two mutually symmetrical fixed seats 3. A reinforcing plate 8 is fixedly connected between the two mutually symmetrical fixed seats 3. The fixed seats 3 have several threaded holes 4. Several connecting seats 5 are detachably connected to the fixed seats 3. The connecting seats 5 have several round holes 6 that match the threaded holes 4. A buffer mechanism is rotatably connected to the connecting seats 5. The fixed seats 3 and the connecting seats 5 are fixed together by several hexagonal bolts 7.

[0021] The anti-collision device for road engineering in this utility model is similar in structure to the existing municipal road guardrail. For example, the patent with announcement number CN219808306U discloses a municipal road guardrail. The main improvement of this utility model is that, through the design of the buffer mechanism, it can play a role in buffering and shock absorption when a vehicle hits the guardrail, reducing the damage to the vehicle and people. At the same time, after installing the buffer mechanism, it can adjust the driving direction of the vehicle and reduce the probability of secondary accidents. As shown in Figures 1 to 3, the anti-collision device for road engineering of this utility model is used by first installing two bases 1 on the road, then snapping the connecting seat 5 onto the fixing seat 3, and using hexagonal bolts 7 to threadedly connect with the threaded holes 4 to fix the buffer mechanism. This facilitates the installation and replacement of the buffer mechanism. When a vehicle hits the guardrail, it will make contact with the buffer mechanism first, thereby buffering and shock-absorbing the vehicle and reducing the damage to the vehicle and people. Furthermore, the buffer mechanism can rotate with the connecting seat 5 to adjust the direction of the vehicle, so that the vehicle gradually moves along the surface of multiple buffer mechanisms instead of immediately bouncing back at a reversing angle or rolling after the impact. This device can be set on one side of the road or staggered in the middle of the divider of two-way lanes. It is simple, quick and convenient to operate.

[0022] As shown in Figures 1 to 3, the support rod 2 has a second circular hole 9, which penetrates the lower surface of the base 1.

[0023] Specifically, before installing this guardrail, pre-embedded holes can be drilled in the road. A rod can be inserted through the round hole 29 and into the ground. After the guardrail is hit by a vehicle, the rod inserted into the ground can enhance the stability of the guardrail and further reduce the possibility of it falling over.

[0024] As shown in Figure 3, the fixed base 3 includes an L-shaped support plate 301 fixedly connected between two support rods 2. The L-shaped support plate 301 has several equally spaced slots 302, and threaded holes 4 are located on both sides of the slots 302.

[0025] Specifically, the L-shaped support plates 301 on the two fixed seats 3 are used to support the connecting seat 5, while the slots 302 are used to limit the position of the connecting seat 5.

[0026] As shown in Figure 3, the connecting seat 5 includes a locking block 501 that is adapted to the two locking slots 302. Side plates 502 are fixedly connected to both sides of the two locking blocks 501. A circular hole 6 is opened on the side plate 502. A rotating shaft 503 is fixedly connected between the two locking blocks 501.

[0027] Specifically, the two locking blocks 501 at the upper and lower ends of the rotating shaft 503 are respectively locked into the two symmetrical locking slots 302. At this time, the round hole 6 on the side plate 502 and the threaded hole 4 on the L-shaped support plate 301 are aligned, which makes it easy to use hex bolts 7 to fix the side plate 502, thereby fixing the entire connecting seat 5. This completes the installation of the connecting seat 5 and the buffer mechanism. Similarly, by performing the opposite operation, the damaged buffer mechanism can be removed for repair and replacement.

[0028] As shown in Figure 3, the buffer mechanism includes a roller 10 rotatably connected to a rotating shaft 503, a buffer pad 11 installed on the outer wall of the roller 10, and reflective markings provided on the buffer pad 11.

[0029] Specifically, the buffer pad 11 can buffer and absorb shocks, reducing damage to vehicles and people. The roller 10 can rotate with the rotating shaft 503, so that when the vehicle hits the buffer pad 11, the roller 10 will also be rotated under force, causing the impact part of the vehicle to gradually move along the direction of multiple buffer mechanisms, instead of the vehicle being directly bounced up and turned around to move in other directions. This can reduce the probability of the vehicle rolling over after the impact, further protecting the safety of the vehicle and people. The reflective markings can also help the driver to see the presence of the guardrail at night.

[0030] As shown in Figure 3, the inside of the roller 10 is provided with a cavity 12, and a reinforcing rod 13 is fixedly connected to the inner wall of the cavity 12.

[0031] Specifically, by using the cavity 12 and the reinforcing rod 13, the strength of the roller 10 is ensured while its weight is reduced, thus facilitating daily maintenance and replacement.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
