Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, specifically a traffic safety guidance device for highway maintenance and construction. Background Technology

[0002] Highway maintenance and construction refers to the routine maintenance, repair, and upgrading of highways and their ancillary facilities through planned and organized technical means and management measures to ensure the continuity of road traffic capacity, safety, and service life. Its scope covers multiple aspects such as pavement repair, bridge and tunnel inspection, sign and marking updates, and drainage system cleaning, aiming to prevent and treat road defects and restore or improve the service performance of highways. Traffic safety refers to the comprehensive concept of preventing and reducing traffic accidents in the road traffic environment through multiple means such as scientific management, technology application, law enforcement, and education and publicity, ensuring the safety of people, vehicles, and road facilities, and achieving the efficient and orderly operation of the traffic system.

[0003] Based on existing highway traffic safety guidance devices, it has been found that during highway operation, the temporary work of maintenance vehicles is an important link in ensuring road safety and traffic efficiency. However, these vehicles and related facilities often become potential safety hazards in high-speed driving environments. In particular, during maintenance operations, traffic cones are usually used as warning facilities, but they have significant limitations in practical applications and are difficult to effectively meet the safety needs of high-speed driving environments.

[0004] Based on this, this utility model designs a traffic safety guidance device for highway maintenance construction to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model includes a guiding mechanism. Firstly, through the multi-level dynamic display of the first and second LED warning screens (such as progressively increasing flashing frequencies), a progressive visual warning is formed. Compared with traditional static signs, dynamic information is more likely to attract the driver's attention. Secondly, the adjustable warning reflective strip can be adjusted to a length of 100 meters via a roller, which can adapt to the needs of different lane widths and avoid the spatial compression of traffic flow by fixed guardrails. Thirdly, the combination of support rods and straps for fixing adopts a three-point anchoring structure, which greatly improves stability compared to traditional sandbag counterweights.

[0015] 2. In this utility model, a warning mechanism is provided, which uses a laser matrix composed of a first laser spotlight and a second laser spotlight to form a three-dimensional warning light network. The first laser spotlight and the second laser spotlight use 635nm wavelength laser, which can penetrate up to 800 meters in foggy weather, improving visibility several times over compared to ordinary LED warning lights. This laser warning mechanism can enable drivers to detect the construction area tens of seconds in advance, and its warning effect is superior to that of traditional cones.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 In this embodiment of the utility model, a traffic safety guidance device for highway maintenance construction includes a first counterweight platform 1, with a first roller 2 installed at the lower end of the first counterweight platform 1. A second counterweight platform 3 is arranged behind the first counterweight platform 1, with a second roller 4 installed at the lower end of the second counterweight platform 3. Guiding mechanisms 5 and warning mechanisms 6 are provided on both the first and second counterweight platforms 1 and 3. The guiding mechanism 5 includes a first electrical control box 501, a first LED warning screen 502, a first loudspeaker 503, a first roll hopper 504, and a warning reflective strip 507. The first electrical control box 501 is fixedly installed at the upper end of the first counterweight platform 1. The first LED warning screen 502 is installed at the front end of the first electrical control box 501. The first loudspeaker 503 is installed at the upper end of the first LED warning screen 502. The first roll hopper 504 is fixedly installed at the upper end of the first electrical control box 501. The interior of the first roll hopper 504... The guide mechanism 5 is equipped with a warning reflective strip 507 and includes a winding rod 505 and a rotating handle 506. The winding rod 505 is installed in the middle of the first winding compartment 504, and the rotating handle 506 is fixedly installed at the upper end of the winding rod 505. The warning reflective strip 507 is wound on the winding rod 505. The first power supply battery 508 is fixedly installed at the rear end of the first electrical control box 501. The second electrical control box 509 is fixedly installed at the upper end of the second counterweight 3. The second LED warning screen 510 is installed at the front end of the second electrical control box 509. The second loudspeaker 511 is installed at the upper end of the second LED warning screen 510. The second winding compartment 512 is fixedly installed at the upper end of the second electrical control box 509. The second power supply battery 513 is fixedly installed at the rear end of the second electrical control box 509. The support rods 514 are fixedly installed at the right ends of both the first electrical control box 501 and the second electrical control box 509. The straps 515 are installed on the support rods 514.

[0028] The guidance mechanism 5 combines a display component, a loudspeaker component, a guidance component, and a positioning component. The display component uses a first electrical control box 501 paired with a first LED warning screen 502, which can flash red and blue warning lights and display information such as construction ahead. The loudspeaker component uses a first high-volume speaker 503 to project warning sounds over a longer distance, ensuring that drivers at a distance are aware of the road construction situation ahead. The guidance component uses an adjustable reflective warning strip 507; extending a long reflective strip 507 along the roadside provides effective warning without obstructing the road frame or affecting traffic, thus enhancing safety. The positioning component uses a support rod 514 and straps 515 to secure the entire device to the guardrail on the side of the road, ensuring installation stability. Upon activation, it is essential to ensure that the first battery 508 and the second battery 513 are fully charged and that the first electrical control box 501 and the second electrical control box 509 are connected to the control terminal. During activation, the construction vehicle should place the device 150 meters behind the road construction area within the guidance mechanism 5. When placing the first counterweight platform 1, the first electrical control box 501, and the components on the first electrical control box 501, support rods 514 and straps 515 are needed to fix the first electrical control box 501 to the road guardrail. Then, the warning content of the first LED warning screen 502 and the broadcast content of the first loudspeaker 503 are adjusted through the control terminal and the first electrical control box 501. Subsequently, the staff adjusts the position of the second counterweight platform 3, the second electrical control box 509, and the components on the second electrical control box 509, which can be moved forward by fifty to one hundred meters. Following the method of controlling the first electrical control box 501, the second electrical control box 509, the second LED warning screen 510, and the second loudspeaker 511 are adjusted. The difference is that a warning reflective strip 507 is set between the first electrical control box 501 and the second electrical control box 509. The warning reflective strip 507 can be extended for tens or even nearly a hundred meters, which can play a very effective warning role. In summary, the guiding mechanism 5 integrates visual and auditory dual warning functions, which can effectively remind and guide the driver, and improve construction safety.

[0029] The warning mechanism 6 includes a first mounting platform 601, a first support frame 602, and a first laser spotlight 603. The first mounting platform 601 is fixedly installed on the left end of the first electrical control box 501. The first support frame 602 is fixedly installed on the first mounting platform 601, and the first laser spotlight 603 is installed on the first support frame 602. The warning mechanism 6 also includes a second mounting platform 604, a second support frame 605, and a second laser spotlight 606. The second mounting platform 604 is fixedly installed on the left end of the second electrical control box 509. The second support frame 605 is fixedly installed on the second mounting platform 604, and the second laser spotlight 606 is installed on the second support frame 605.

[0030] The warning mechanism 6 uses a high-penetration laser as a warning light. Unlike traditional traffic safety guidance devices, the lasers emitted by the first laser spotlight 603 and the second laser spotlight 606 have very strong penetrating power, allowing drivers on highways to see and notice the lasers from several kilometers away. The upward beams of the first laser spotlight 603 and the second laser spotlight 606 do not affect the driver's driving safety, but only serve as an early warning function. When the driver notices the laser, he can understand that there may be construction or other situations on the road ahead, thereby allowing the driver to concentrate on driving the vehicle and ensuring driving safety.

[0031] The working principle of this utility model is as follows: Through the coordinated operation of the guiding mechanism 5 and the warning mechanism 6, this device forms a multi-dimensional, long-distance composite warning system in the highway maintenance and construction area. The construction vehicle places the first counterweight platform 1 and the second counterweight platform 3 150 meters and 50-100 meters behind the construction area, respectively. The device is fixed to the road guardrail by the support rod 514 and the strap 515. When the guiding mechanism 5 is activated, the first LED warning screen 502 and the second LED warning screen 510 simultaneously display red and blue warning lights and the dynamic text "Construction Ahead" in conjunction with the first high-volume speaker 503 and the second high-volume speaker 511 playing in a loop. The system issues a warning voice (such as "Construction ahead, slow down"), creating a visual and auditory warning coverage within a range of hundreds of meters. Workers rotate the handle 506 to unfold the warning reflective tape 507 in the first roll 504 and the second roll 512. The length is adjusted by the rolling rod 505 to form a continuous reflective barrier. This avoids the problem of traditional cones occupying lanes and achieves all-weather reflective warning through high reflective materials. In the warning mechanism 6, the first laser spotlight 603 and the second laser spotlight 606 emit red laser beams upwards. Utilizing their strong penetrating power, they can still form a visible light curtain of more than 1 kilometer in rainy and foggy weather. The battery provides power to the entire system.
