[0024] 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.

[0025] like Figure 1 , Figure 2 As shown, an automatic flag-waving device for highway maintenance construction includes: an equipment platform 1; a gear assembly 2 mounted on the equipment platform 1, the gear assembly 2 including a driving gear 21 and two driven gears 22; an eccentric rod 3 mounted on the driven gears 22; a swing arm 4 rotatably connected to the equipment platform 1, the eccentric rod 3 passing through the rear end of the swing arm 4; a warning sign 5 mounted on the front end of the swing arm 4; a warning flag 6 detachably connected to the swing arm 4; a lifting base 7 mounted at the bottom of the equipment platform 1; and a monitor 8 mounted on the top of the equipment platform 1.

[0026] like Figure 3 As shown, the top of the equipment platform 1 is provided with a connecting plate 11. There are three connecting plates 11. The connecting plates 11 are respectively located behind the two driven gears 22 and the driving gear 21. The driven gears 22 are rotatably connected to the connecting plate 11. The output end of the motor 12 is fixedly connected to the rear end of the driving gear 21. The fixed end of the motor 12 is fixedly connected to the connecting plate 11. Both driven gears 22 mesh with the driving gear 21. When in use, the motor 12 is started, and the motor 12 drives the driving gear 21 to rotate. The driving gear 21 drives the driven gears 22 to rotate.

[0027] When the driven gear 22 rotates, it drives the eccentric rod 3 to rotate. The eccentric rods 3 on the two driven gears 22 face opposite directions, making the flag-waving range wider and making the device easier for vehicles to spot, thus enhancing the warning effect.

[0028] The front end of the eccentric rod 3 is provided with a pendulum ball 31. The diameter of the pendulum ball 31 is larger than the diameter of the eccentric rod 3. The outer wall of the pendulum ball 31 is smooth, making the rotation of the pendulum rod 4 smoother.

[0029] The rear end of the pendulum rod 4 is a perforated plate 41 with an elongated hole 411. The size of the elongated hole 411 is larger than the size of the pendulum ball 31, and the vertical height of the elongated hole 411 is smaller than the rotation range of the pendulum ball 31. When the driven gear 22 drives the pendulum ball 31 to rotate within the elongated hole 411, the pendulum ball 31 contacts the inner wall of the elongated hole 411, causing the perforated plate 41 to move up and down, thus achieving the oscillating effect. The driving gear 21 drives the two driven gears 22 to rotate together, causing the perforated plates 41 on both sides to rotate simultaneously.

[0030] The front end of the swing arm 4 is a rod body 42, which is perpendicularly fixed to the perforated plate 41. The front end of the rod body 42 faces outward from the device and is positioned within the visibility range of the traveling vehicle. A rotating shaft 13 is provided on the equipment platform 1, and the rod body 42 is rotatably connected to the rotating shaft 13. When the perforated plate 41 moves up and down, it is driven to rotate up and down around the rotating shaft 13, achieving a rocking effect.

[0031] Both pole 42 and warning sign 5 are equipped with light strips 9. At night or in weather with poor visibility, the light strips 9 can increase the warning range. The warning sign 5 has a large area, and together with the light strips 9, it can be more easily spotted when it is shaken. Both pole 42 and warning sign 5 are equipped with light strips 9 on both sides, which can remind oncoming vehicles on one side and provide lighting for construction and maintenance on the other side, facilitating the construction and maintenance work.

[0032] A threaded sleeve 421 is provided on the pole 42, located inside the warning disc. The pole of the warning flag 6 is threaded, and the warning flag 6 is screwed onto the threaded sleeve 421. In clear weather with good visibility, the pole of the warning flag 6 is screwed into the threaded sleeve 421 to provide a speed reduction warning. The lights on the light strip 9 can be turned off in good visibility to save energy. The warning flag 6 uses a bright color such as red or orange-yellow to make it easy for drivers to spot the device. The warning flag 6 is easily damaged; the threaded connection facilitates disassembly. Removing and storing the warning flag 6 when not in use increases its lifespan and makes it easier to replace when damaged.

[0033] The lifting mechanism is used to adjust the height of the flag, making the device more noticeable to drivers. The lifting base 7 includes a bracket 71, an electric telescopic rod 72, and a limiting rod 73. The limiting rod 73 is fixed to the side wall of the equipment platform 1 and slidably connected to the bracket 71. The limiting rod 73 restricts the equipment platform 1 to move only vertically, reducing the swaying of the equipment platform 1 and mitigating the airflow generated when cars pass by at high speeds. The fixed end of the electric telescopic rod 72 is fixed to the bracket 71, and the telescopic end of the electric telescopic rod 72 is fixed to the bottom of the equipment platform 1. When it is necessary to adjust the height of the flag, the height is adjusted by telescopically extending the electric telescopic rod 72, thereby making the flag more conspicuous.

[0034] The lower part of the side wall of the bracket 71 is equipped with a set of casters 711, and the upper part of the side wall of the bracket 71 is equipped with a handle 712. During normal flag waving, the bottom surface of the bracket 71 is in contact with the ground, and the casters 711 are not in contact with the ground. The device is kept stable on the ground by the friction of the bottom surface of the bracket 71. When it is necessary to move the device, the handle 712 is pulled by hand to tilt the device. At this time, the casters 711 are in contact with the ground, the friction is small and it is easy to move.

[0035] Monitor 8 is oriented towards the direction of oncoming traffic. Monitor 8 is used to record oncoming traffic data, and in the event of a collision, it is easy to retrieve relevant video information.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
