[0002] Warning devices for road and bridge construction refer to information display devices used to indicate failures, accidents or dangerous situations during road and bridge construction. Such devices usually include but are not limited to warning signs, warning lights, guardrails, etc. They can not only remind passing vehicles and pedestrians to pay attention to the construction area through obvious warning signs and lights, avoid entering or approaching the construction area, and ensure construction safety, but also effectively prevent construction machinery and personnel from operating incorrectly, reduce safety accidents caused by incorrect operation, and improve the safety of the construction site. Warning devices for road and bridge construction are widely used in various infrastructure construction projects such as roads, bridges, tunnels, etc.

[0003] Chinese patent announcement number CN215758659U discloses a warning device for road and bridge engineering construction, which relates to the technical field of road and bridge construction, and in particular to a warning device for road and bridge engineering construction, comprising a shell, wherein the inner bottom of the shell is symmetrically protruding upward, the bottom of the shell is provided with a supporting mechanism, and the supporting mechanism is used to support the bottom of the shell, a mounting shell with a shell opening is fixedly installed on the top of the shell, a plurality of reflective strips are fixedly bonded in the mounting shell, a perspective plate is fixedly installed at the shell opening of the mounting shell, a motor is fixedly installed on one side of the outer wall of the shell, one end of the output shaft of the motor penetrates the shell and extends to the inside thereof, and then a screw is fixedly connected, and one end of the screw away from the motor is rotatably connected to the inner wall of the shell; the motor is started, and under the transmission of the rack and the convex gear, a brush installed on one side of the mounting plate is conveniently driven to swing forward, and then the brush is conveniently wiped off the dust attached to the surface of the perspective plate under the spraying of the spraying mechanism.

[0004] In actual use, the utility model is usually deployed at a construction site to serve as a warning. However, the floor space of existing warning devices is usually fixed. When encountering external forces such as wind and passing vehicles, they are prone to shaking or tipping over due to insufficient stability, which will affect their warning effect. If the floor space of the warning device is expanded simply to increase stability, it will not only increase the difficulty of transportation and handling, but also take up more space during storage, making the warning device for road and bridge construction less practical.

[0027] Embodiment 1:

[0028] See also Figure 1-4 The utility model provides a warning device for road and bridge engineering construction, comprising:

[0029] A base plate 1 and two support plates 2;

[0030] The warning plate 3 is arranged between the two support plates 2. A fixing plate 4 is arranged between the two support plates 2. The fixing plate 4 is penetrated by fixing holes.

[0031] A threaded rod 5 is inserted into the fixing hole, and external threads on both sides of the threaded rod 5 are arranged in opposite directions. The bottom ends of the two support plates 2 are provided with a same adjustment plate 6;

[0032] A rectangular groove is provided through the base plate 1 , and matching extension plates 7 are provided on both sides of the rectangular groove. The ends of the two extension plates 7 respectively pass through the two ends of the rectangular groove and extend to the outside.

[0033] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a servo motor 8 is provided on one side of the upper end of the fixed plate 4. The servo motor 8 is a prior art and will not be described in detail here. A first bevel gear 9 is provided on the outer side of the threaded rod 5, and a second bevel gear 10 meshing with the first bevel gear 9 is provided on the output end of the servo motor 8. When the servo motor 8 is started, its output end will drive the second bevel gear 10 to rotate, thereby driving the first bevel gear 9 and the threaded rod 5.

[0034] Specifically, Figure 2 , Figure 3 and Figure 4 As shown, a limiting groove is provided on the side wall of the fixing hole, and a limiting ring 11 matching the limiting groove is provided on the outer side of the threaded rod 5. The limiting ring 11 is located in the limiting groove and is slidably connected to the side wall of the limiting groove.

The two guide grooves can limit the moving position of the adjustment plate 6 to prevent it from rotating with the threaded rod 5.

[0039] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, both sides of the adjustment plate 6 are rotatably connected with multiple connecting rods 13, and the other ends of the multiple connecting rods 13 are respectively rotatably connected to one side of the upper ends of the two extension plates 7. When the adjustment plate 6 moves, the two extension plates 7 can be driven to move by the multiple connecting rods 13 respectively. One end of the two extension plates 7 is rotatably connected with multiple moving wheels 14, and the multiple moving wheels 14 can make the two extension plates 7 move more smoothly.

[0040] See also Figure 1-4 When using the warning device for road and bridge engineering construction, it is necessary to start the servo motor 8 first. The output end of the servo motor 8 will drive the second bevel gear 10 to rotate, and the second bevel gear 10 will drive the first bevel gear 9 and the threaded rod 5 to rotate. The threaded rod 5 will drive the warning plate 3 to move upward to achieve a warning effect. When the threaded rod 5 rotates, it will also drive the adjustment plate 6 to move downward. The adjustment plate 6 will drive multiple connecting rods 13 to move, and the multiple connecting rods 13 will respectively drive the two extension plates 7 to move outward, thereby increasing the footprint of the warning device for road and bridge engineering construction, ensuring its stability during use, and preventing it from shaking or tipping over.
