[0020] 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.

[0021] Example:

[0022] Please see Figure 1 - Figure 4 This embodiment of a highway construction and maintenance device includes a left side plate 1, a right side plate 2, and a middle plate 3. The left side plate 1 and the right side plate 2 are hinged to the middle plate 3. The left side plate 1 and the right side plate 2 are rotatable relative to the middle plate 3. A lifting assembly 4 is connected to the back of the middle plate 3 to drive the middle plate 3, the left side plate 1, and the right side plate 2 to move up and down as a whole. At the same time, a second telescopic rod 5 is rotatably connected to each side of the back of the middle plate 3. The other ends of the two second telescopic rods 5 are rotatably connected to the left side plate 1 and the right side plate 2, respectively. The function of the second telescopic rods 5 is to adjust the relative angle between the left side plate 1, the right side plate 2, and the middle plate 3. Spray heads 6 are connected to the bottom of side panel 1, right side panel 2, and middle panel 3. Spray heads 6 are used for direct water spraying and maintenance. When the second telescopic rod 5 is extended to its longest length, the left side panel 1, right side panel 2, and middle panel 3 are parallel, thus spraying and maintaining adjacent lanes. When the second telescopic rod 5 is at its shortest length, the left side panel 1 and right side panel 2 are perpendicular to the middle panel 3. At this time, the left side panel 1 and right side panel 2 are located on both sides inside the truck bed, storing the equipment. By adjusting the extension and retraction of the second telescopic rod 5, and coordinating with the lifting action of the lifting component 4, the effect of watering and maintaining multiple lanes can be achieved, and the equipment can be stored in the truck bed for easy transportation when not in use.

[0023] Furthermore, rotating rods 10 are rotatably connected to the bottom of the left side plate 1, the right side plate 2, and the middle plate 3. Multiple spray heads 6 are fixedly connected to the outer side of the rotating rods 10. An adjusting ring 11 is fixedly connected to one end of the rotating rod 10 near the rotating support. Rotating the adjusting ring 11 can adjust the angle of the multiple spray heads 6. The rotating rod 10 can drive the spray heads 6 to rotate. Multiple positioning holes 12 are evenly opened on the surface of the adjusting ring 11. A spring pin 13 is installed on the surface of the rotating support near the adjusting ring 11. The spring pin 13 contains a spring. Pressing the spring pin 13 causes one end of the spring pin 13 to disengage from the positioning hole 12. Then, rotating the adjusting ring 11 can adjust the angle of the spray head 6.

[0024] Striped warning boards 16 are fixedly connected to the top of the left side panel 1 and the right side panel 2, making the equipment more conspicuous and warning vehicles and pedestrians behind, thus improving safety during construction. At the same time, the bottom of the fixed seat 8 is connected to the inner side of the carriage, and a water tank 14 is installed inside the carriage. Diverter 15 is fixedly installed on the back of the left side panel 1, the right side panel 2 and the middle panel 3. The upper end of the diverter 15 is connected to the water tank 14 through a water pump. The bottom of the diverter 15 has multiple interfaces, and multiple spray heads 6 are connected to the bottom of the diverter 15 through pipes.

[0025] The lifting assembly 4 includes a first telescopic rod 401, two first connecting rods 402, and two second connecting rods 403. A connecting rod 7 is fixedly connected between the two first connecting rods 402. One end of the first telescopic rod 401 is rotatably connected to the connecting rod 7, and the other end of the first telescopic rod 401 is rotatably connected to a fixed base 8. A mounting plate 9 is fixedly connected to the back of the intermediate plate 3. The first connecting rods 402 and the second connecting rods 403 are parallel. One end of both the first connecting rod 402 and the second connecting rod 403 is rotatably connected to the mounting plate 9, and the other end of both the first connecting rod 402 and the second connecting rod 403 is rotatably connected to the fixed base 8. Next, the sides of the first telescopic rod 401, the first connecting rod 402, and the fixed seat 8 are triangular. When the first telescopic rod 401 is shortened, it drives the first connecting rod 402 to rotate around the connection point near the fixed seat 8. Since the first connecting rod 402 is parallel to the second connecting rod 403, and the line connecting the rotation points on the same side of the two connecting rods is perpendicular to the bottom surface of the carriage, the mounting plate 9 remains vertical while moving upward. When the mounting plate 9 moves upward, it drives the middle plate 3, the left plate 1, and the right plate 2 to move upward. If the mounting plate 9 does not remain vertical, the left plate 1 and the right plate 2 will tilt after folding.

[0026] The working principle of the above embodiment is as follows: the relative angle between the left side plate 1, the right side plate 2, and the middle plate 3 is adjusted by the extension and retraction of the second telescopic rod 5. At the same time, the extension and retraction of the first telescopic rod 401 in the lifting assembly 4 drives the first connecting rod 402 and the second connecting rod 403 to move, so that the mounting plate 9 moves the middle plate 3, the left side plate 1, and the right side plate 2 up and down while keeping them vertical. The rotating rod 10, the adjusting ring 11, and the spring pin 13 work together to adjust the angle of the spray head 6. The water tank 14, the water pump, the diverter 15, and the pipes form a water supply system to supply water to the spray head 6. The striped warning plate 16 serves as a warning. In use, the angle of the spray head 6 is first adjusted by the extension and retraction of the second telescopic rod 5. Component 4 lowers the device to a suitable height, then extends the second telescopic rod 5 to make the left side panel 1, right side panel 2, and middle panel 3 parallel. Next, press the spring pin 13 to adjust and fix the angle of the spray head 6. Then, start the water pump. Water in the water tank 14 is sprayed from the spray head 6 through the diverter 15 and pipes to maintain the multi-lane road. After use, turn off the water pump, raise the device above the bottom of the vehicle body using the lifting component 4, and then shorten the second telescopic rod 5 to make the left side panel 1, right side panel 2, and middle panel 3 perpendicular. At this time, the left side panel 1, right side panel 2, and middle panel 3 are all within the bottom range of the vehicle body. Then, fold up the side panels of the vehicle body to complete the storage.
