Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art in the technical field without creative work shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-6 , the anti-collision grading warning device of the highway maintenance vehicle in this embodiment includes a counterweight base 1. The upper surface of the counterweight base 1 is provided with a support rod 2. The lower end of the support rod 2 is located in the middle of the counterweight base 1. The upper end of the support rod 2 is provided with a warning sign 3. A warning slogan is printed on the warning sign 3, and the warning slogan is printed with a reflective material. A reflective strip 12 is attached to the outer wall edge of the warning sign 3. A vibration marking plate 4 is movably installed on one side of the counterweight base 1. A deceleration rib 5 is movably installed on the upper surface of the vibration marking plate 4. The outer wall of the deceleration rib 5 is coated with a reflective warning coating 11 in multiple places.

[0025] Such as Figure 1 、 2As shown, the highway maintenance warning device in the present utility model is similar to the existing highway maintenance warning devices. The main improvement of the present utility model lies in carrying out warnings at different levels according to the content of highway maintenance to ensure that drivers are reminded and reduce the possibility of car accidents. When highway maintenance is required in the present utility model, if the degree of highway maintenance is small, such as little or no occupation of the road, the warning sign 3 can be directly erected behind the highway at the maintenance location. The warning sign 3 is supported by the support rod 2 in cooperation with the counterweight base 1, and the driver is reminded through the warning slogan on the warning sign 3. The reflective strips 12 on the warning sign 3 cooperate with the reflective warning slogan to facilitate the driver to see the reminder at night. The number of warning signs 3 is not limited. If the highway maintenance is at a medium level, such as occupying part of the road, the warning sign 3 can be erected behind the highway at the maintenance location, and the vibrating marker board 4 can be laid on one side of the counterweight base 1 so that the vibrating marker board 4 is laid on the highway. At this time, when the vehicle is driving on the highway, a certain vibration is generated through the vibrating marker board 4, and then the warning slogan on the warning sign 3 is used to warn the driver of the highway maintenance ahead. The number of warning signs 3 and vibrating marker boards 4 is not limited. If the highway is under high-level maintenance, such as occupying most of the road or having a certain stepped road repair for all roads, the warning sign 3 can be erected behind the highway at the maintenance location, and the vibrating marker board 4 can be laid on one side of the counterweight base 1 so that the vibrating marker board 4 is laid on the highway. Then the deceleration convex strips 5 are installed on the vibrating marker board 4. The height of the protrusion of the deceleration convex strips 5 is relatively high, so that the vehicle needs to decelerate to drive stably when passing over the deceleration convex strips 5. Then the warning slogan on the warning sign 3 is used to warn the driver, so that the vehicle decelerates and passes through the maintenance section. The number of warning signs 3, vibrating marker boards 4 and deceleration convex strips 5 is not limited. The reflective warning coating 11 sprayed on the outer wall of the deceleration convex strips 5 enables the driver to see the deceleration convex strips 5 at night, reducing the occurrence of car accidents. By carrying out warnings at different levels according to different degrees of highway maintenance, the smoothness of the road is not affected during minor maintenance of the highway, and the driver can be actively warned during major repairs of the highway, reducing the occurrence of car accidents.

[0026] As Figure 1 , 5 As shown, the number of vibrating marker boards 4 is multiple. One of the vibrating marker boards 4 is installed on the side wall of the counterweight base 1, and one side of two adjacent vibrating marker boards 4 is in contact. The length of the deceleration convex strips 5 is equal to the length of the vibrating marker board 4. When using the vibrating marker board 4, according to the length required to be laid on the highway, single or multiple vibrating marker boards 4 are selected for placement, and the combined vibrating structure facilitates the transportation and use of the vibrating marker board 4.

[0027] As Figure 2 , 3As shown in the figure, the support rod 2 includes an outer sleeve rod 21 installed on the upper surface of the counterweight base 1. The inner wall of the outer sleeve rod 21 is slidably connected with an inner sliding rod 22. The outer sleeve rod 21 is slidably connected to the outer wall of the inner sliding rod 22. The outer wall of the outer sleeve rod 21 is threadedly connected with a first bolt 23. One end of the first bolt 23 abuts against the outer wall of the inner sliding rod 22. A fixing sleeve 25 is movably sleeved on the outer wall of the upper end of the inner sliding rod 22. The outer wall of the fixing sleeve 25 is threadedly connected with a second bolt 26. One end of the second bolt 26 abuts against the outer wall of the inner sliding rod 22. The warning sign 3 is fixedly connected to the side wall of the fixing sleeve 25. The inner sliding rod 22 can slide in the outer sleeve rod 21, and the inner sliding rod 22 is fixed by the first bolt 23. With the cooperation of the fixing sleeve 25, it is convenient to adjust the height of the warning sign 3. At the same time, when not in use, the height can be reduced, which is convenient for transportation. The warning sign 3 is installed at the upper end of the inner sliding rod 22 through the fixing sleeve 25. The fixing sleeve 25 can rotate on the outer wall of the inner sliding rod 22 and is fixed by the second bolt 26. Thus, the warning sign 3 and the inner sliding rod 22 can be disassembled and assembled, reducing the transportation space. At the same time, the angle of the warning sign 3 can be adjusted to meet different warning requirements.

[0028] As Figure 2 shown in the figure, the support rod 2 further includes a threaded column 24 fixedly connected to the lower end surface of the outer sleeve rod 21. A threaded groove 6 is opened on the upper surface of the counterweight base 1. The threaded column 24 is threadedly connected with the threaded groove 6. The outer sleeve rod 21 is threadedly connected with the threaded groove 6 through the threaded column 24 at its bottom surface, realizing the installation of the outer sleeve rod 21 and the counterweight base 1. The outer sleeve rod 21 and the counterweight base 1 can be disassembled, reducing the transportation space and being convenient to carry.

[0029] As Figure 3 、 4 shown in the figure, a round hole 13 is opened on the side wall of the warning sign 3. A speed limit sign 14 is movably placed in the round hole 13. Different speed limit values are provided on both sides of the speed limit sign 14. One end of the warning sign 3 is threadedly connected with a third bolt 15. A jack 16 is opened on the edge of the speed limit sign 14. One end of the third bolt 15 is movably inserted into the jack 16. The speed limit sign 14 rotates in the round hole 13 through the cooperation of the third bolt 15 and the jack 16. The speed limit sign 14, in cooperation with the warning slogan on the warning sign 3, can prompt the driver of the driving speed. And the speed limit sign 14 rotates in the round hole 13 through the support of the jack 16 on its outer wall in cooperation with the third bolt 15. The speed limit values on both sides of the speed limit sign 14 are different. According to the different degrees of highway maintenance, different speed limit values are shown on the outside to prompt the driver. After the third bolt 15 is tightened, it abuts against one end of the inner wall of the round hole 13, thus restricting the speed limit sign 14 and making it unable to rotate. At the same time, after the third bolt 15 is removed from the warning sign 3, the speed limit sign 14 can be taken out of the round hole 13 for replacement. Thus, multiple different speed limit values can be prompted without replacing the entire warning sign 3, reducing costs and at the same time adapting to different degrees of highway maintenance.

[0030] AsFigure 1 , 2 As shown in Fig. 5, limiting card slots 7 are provided on the upper surface of the counterweight base 1 and the upper surface of one end of the vibration marking plate 4. Limiting blocks 8 are fixedly connected to one end of a plurality of vibration marking plates 4. Adjacent two vibration marking plates 4 are movably clamped through the cooperation of the limiting blocks 8 and the limiting card slots 7. The limiting block 8 at the end of one of the vibration marking plates 4 close to the counterweight base 1 is movably clamped with the limiting card slot 7 on the counterweight base 1; the vibration marking plate 4 is connected to the counterweight base 1 and a plurality of vibration marking plates 4 by inserting the limiting block 8 at its end into the limiting card slot 7 on the counterweight base 1 or the limiting card slot 7 on the adjacent vibration marking plate 4, so that the vibration marking plate 4 is stably placed on the road.

[0031] As Figure 5 , 6 shown, vibration grooves 9 are longitudinally and transversely provided on the upper surface of the vibration marking plate 4. A grid clamping plate 10 corresponding to the vibration grooves 9 is fixedly connected to the bottom surface of the deceleration convex strip 5. The grid clamping plate 10 is movably clamped with the vibration grooves 9; when a vehicle passes by, the vibration grooves 9 provided on the vibration marking plate 4 enhance the vibration feeling of the vehicle, thereby warning the driver. When the deceleration convex strip 5 is installed with the vibration marking plate 4, the grid clamping plate 10 at the bottom surface of the deceleration convex strip 5 is inserted into the vibration grooves 9, and the vibration grooves 9 cooperate with the grid clamping plate 10 to limit the deceleration convex strip 5, so that the deceleration convex strip 5 cannot move horizontally. Furthermore, when the vehicle travels onto the deceleration convex strip 5, the deceleration convex strip 5 will not move out of the vibration marking plate 4, ensuring stability.

[0032] Implementation steps in this embodiment: When highway maintenance is required, if the degree of highway maintenance is low, such as little or no occupation of the road, the warning sign 3 can be directly erected behind the highway at the maintenance location. The warning sign 3 is supported by the support rod 2 and the counterweight base 1. The driver is prompted by the warning slogan and speed limit sign 14 on the warning sign 3. The number of warning signs 3 is not limited. If the highway maintenance is at a medium level, such as when part of the road is occupied, the warning sign 3 can be erected behind the highway at the maintenance location, and the vibration marking plate 4 is laid on one side of the counterweight base 1. The vibration marking plate 4 is connected to the counterweight base 1 and multiple vibration marking plates 4 are connected by inserting the limit block 8 at its end into the limit slot 7 on the counterweight base 1 or the limit slot 7 on the adjacent vibration marking plate 4, so that the vibration marking plate 4 is laid on the highway. At this time, when the vehicle is driving on the highway, a certain vibration is generated by the vibration marking plate 4 and the vibration groove 9, and then the warning slogan and speed limit sign 14 on the warning sign 3 are used to warn the driver that the highway ahead is under maintenance. The number of warning signs 3 and vibration marking plates 4 is not limited. If the highway is under high-level maintenance, such as when most of the road is occupied or there is a certain stepped road repair for all roads, the warning sign 3 can be erected behind the highway at the maintenance location, and the vibration marking plate 4 is laid on one side of the counterweight base 1, so that the vibration marking plate 4 is laid on the highway. The grid card plate 10 at the bottom of the deceleration rib 5 is inserted into the vibration groove 9, and the vibration groove 9 cooperates with the grid card plate 10 to limit the deceleration rib 5, so that the deceleration rib 5 cannot move horizontally. The height of the convex part of the deceleration rib 5 is relatively high, so that the vehicle needs to decelerate when driving over the deceleration rib 5 to drive stably, and then the warning slogan on the warning sign 3 is used to warn the driver, so that the vehicle decelerates through the maintenance section. The number of warning signs 3, vibration marking plates 4 and deceleration ribs 5 is not limited. By making different levels of warnings according to different degrees of highway maintenance, the smoothness of the road is not affected during minor highway maintenance, and the driver can be actively warned during major highway repairs, reducing the occurrence of traffic accidents.
