[0002] In highway bridge construction, the roadbed and pavement are the most important components. The roadbed is the foundation of the pavement structure. A solid and stable roadbed provides an important guarantee for the pavement structure to withstand vehicle loads for a long time. The existence of the pavement structure layer protects the roadbed, preventing it from being directly damaged by vehicles and the atmosphere, and keeping it in a stable state for a long time. During the construction of the highway roadbed, auxiliary devices are needed to protect and warn the construction workers.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention describes an auxiliary construction device for roadbed and pavement of highway bridges.

[0026] In one embodiment, a road bridge subgrade and pavement auxiliary construction device includes: a sign body 100, with multiple flash lamp beads 200 evenly distributed on the front side of the sign body 100, a solar panel 300 folded onto the top of the sign body 100, and a folding mechanism 400 installed on the sign body 100; the folding mechanism 400 includes an unfolding frame 410 rotatably connected to both sides of the sign body 100, the two unfolding frames 410 being fixedly connected by a connecting rod penetrating the interior of the sign body 100, a shrinkage groove 420 being provided on the side of the unfolding frame 410 near the sign body 100, a stabilizing frame 430 being rotatably connected to the shrinkage groove 420 towards the side of the sign body 100, a connecting hole penetrating the surface of the stabilizing frame 430, and locking holes 440 corresponding to the connecting holes being provided on the lower sides of both sides of the sign body 100, with locking bolts 450 threadedly connected to the connecting holes and the locking holes 440.

[0027] like Figure 2 , Figure 4 and Figure 5As shown, the surface of the unfolding frame 410 has shrink holes 460 corresponding to the connecting holes, and the sides of the sign body 100 have fixing holes 470 corresponding to the shrink holes 460. The shrink holes 460, fixing holes 470, locking holes 440, and connecting holes are all threaded holes of the same diameter. The surface of the sign body 100 has ventilation holes 490 evenly spaced from the flash lamp beads 200. The surface of the stabilizer 430 has vertically arranged insertion holes 480.

[0028] In this embodiment, when the sign 100 is unfolded, the unfolding frame 410 is rotated to form a certain angle with the sign 100, and the stabilizing frame 430 is rotated out of the shrinkage groove 420. The stabilizing frame 430 is then fixed in a supported state by passing the locking bolt 450 through the connecting hole of the stabilizing frame 430 and the locking hole 440 of the sign 100. For storage, the locking bolt 450 is unscrewed to retract the stabilizing frame 430 into the shrinkage groove 420. The unfolding frame 410 is rotated to fit against the sign 100, aligning the shrinkage hole 460, fixing hole 470, and connecting hole, and then fixed with the locking bolt 450. This significantly reduces the size of the device, facilitating transportation. The ventilation hole 490 reduces the impact of strong winds on the sign 100, and the insertion hole 480 on the stabilizing frame 430 allows for the insertion of ground stakes or support rods, further enhancing the stability of the device on complex road surfaces and improving the warning effect and stability in adverse weather conditions.

[0029] like Figure 1 and Figure 3 As shown, a ring-shaped reflective strip is fixedly connected to the outer side of the sign body 100, and the flash LEDs 200 are configured as red, blue, and yellow LEDs. An angle adjustment assembly is provided at the folding connection between the solar panel 300 and the sign body 100, including a damping pivot and a limit latch. A battery electrically connected to the solar panel 300 is installed in the lower part of the interior of the sign body 100, and an ambient light sensor electrically connected to the flash LEDs 200 is installed on the front side of the sign body 100. An anti-slip pad is provided at the bottom of the stabilizer 430.

[0030] In this embodiment, the ring-shaped reflective strip of the sign body 100 and the red, blue, and yellow tri-color flashing LED beads 200 form a dual warning system. During the day, the reflective strip enhances visibility, while at night or in low-visibility environments, the flashing LED beads 200 dynamically flash to alert passing vehicles. The solar panel 300 can be tilted at an adjustable angle to ensure efficient absorption of light energy and conversion into electrical energy stored in the battery, powering the flashing LED beads 200 and the ambient light sensor. The ambient light sensor can monitor the light intensity in real time and automatically adjust the brightness and flashing frequency of the flashing LED beads 200 to achieve a balance between energy saving and warning effect. The anti-slip pad at the bottom of the stabilizer 430 increases the friction with the ground, preventing the device from slipping on smooth or sloping surfaces.

[0031] Working principle: Construction personnel can release the lock by moving the limit buckle according to the change of solar altitude angle at different times. By rotating the damping shaft, the tilt angle of the solar panel 300 is adjusted so that the maximum area of ​​the panel faces the sunlight. Then the buckle is released to complete the fixation. The light energy is converted into electrical energy and transmitted to the built-in battery for storage. The battery provides continuous power to electrical components such as the flash lamp 200 and the ambient light sensor. No external power supply is required, which is convenient for auxiliary construction.

[0032] An ambient light sensor monitors the light intensity of the construction area in real time: when the light is sufficient, the ring-shaped reflective strip on the outside of the sign 100 reflects light to enhance recognition; when the light is weak, the sensor triggers the flashing LED 200, which flashes red, blue, and yellow lights alternately, using dynamic light sources to remind passersby to avoid the construction area. The brightness and frequency automatically adjust according to changes in light intensity, balancing energy saving and warning effectiveness. The battery is located inside the lower part of the sign 100, lowering the center of the sign 100 and improving stability.

[0033] The unfolding frame 410 and the stabilizing frame 430 are pulled out and fixed with locking bolts 450 to form a triangular support structure. The anti-slip pads, insertion holes 480, and positioning pins at the bottom of the stabilizing frame 430 further enhance stability, ensuring the device stands stably in strong winds and on slopes. Ventilation holes 490 reduce wind resistance and further improve stability. For storage, the folding mechanism 400 retracts the device. Unscrewing the locking bolts 450 retracts the stabilizing frame 430 into the shrinkage slot 420. The unfolding frame 410 is rotated to fit against the plate body 100, aligning the shrinkage holes 460, fixing holes 470, and connecting holes before securing with locking bolts 450. This reduces the footprint and prevents the device from unfolding on its own during storage, facilitating transportation and storage.

[0034] It should be noted that the solar panel 300, flash LED 200, reflector strip, battery, etc. mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the flash LED 200 can be powered by the built-in power supply. The specific power supply method can be selected according to the situation, which will not be elaborated here.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
