Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to a municipal road maintenance device. Background Technology

[0002] Municipal roads refer to public roads within a city for vehicles and pedestrians. They are a crucial component of urban infrastructure, serving as vital links for traffic flow within and between the city and the outside world, and significantly impacting urban economic development and residents' lives. Maintenance is paramount during the construction and use of municipal roads. This is because, over long-term use, roads are subjected to repeated vehicle loads and the natural environment, making them prone to cracks and potholes. Without timely maintenance, the lifespan of the road and traffic safety will be affected. Maintenance allows for the timely repair of road defects, maintaining the road's good condition and ensuring smooth and safe traffic flow.

[0003] In existing technologies, the water sprayers of municipal maintenance devices are mostly fixed in position, and the water spraying coverage is limited, making it difficult to spray the entire road surface. As a result, some roads are difficult to maintain, resulting in insufficient road maintenance. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a municipal road maintenance device, which aims to improve the problem that the limited coverage of water spraying makes it difficult to spray the entire road surface, resulting in some roads being difficult to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal road maintenance device, comprising a fixed shell, a motor fixedly connected to the outer wall of the fixed shell, a rotating block fixedly disposed at the output end of the motor, a U-shaped frame slidably connected to the outer wall of the rotating block, a crossbar fixedly connected to the outer wall of the U-shaped frame, a rack fixedly connected to the outer end of the crossbar, a rack slidably connected to the inner wall of the fixed shell, a limit post slidably connected to the inner wall of the rack, a limit post fixedly connected to the inner wall of the fixed shell, a gear meshing with the outer wall of the rack, a gear rotatably connected to the outer wall of the gear on the inner wall of the fixed shell, and a water spraying assembly disposed on the inner wall of the fixed shell.

[0007] Preferably, a water sprayer is provided at one end of the water pipe, the outer wall of the water sprayer is fixedly connected to the outer wall of the rack, and the outer wall of the water sprayer is slidably connected to the outer wall of the fixed shell.

[0008] Preferably, a shell is fixedly connected to the lower surface of the fixed shell, and a hydraulic cylinder is fixedly connected to the outer wall of the shell.

[0009] Preferably, a slider is fixedly provided at the output end of the hydraulic cylinder, a U-shaped block is slidably connected to the outer wall of the slider, the upper surface of the slider is slidably connected to the inner wall of the outer shell, and a cross rod is rotatably connected to the outer wall of the slider.

[0010] Preferably, a central column is rotatably connected to the inner wall of the cross rod, and a fixed column is rotatably connected to the inner wall of the cross rod.

[0011] Preferably, a positioning plate is fixedly connected to the lower surface of the fixed column, a U-shaped block II is fixedly connected to the upper surface of the positioning plate, and a horizontal column is slidably connected to the inner wall of the U-shaped block II.

[0012] Preferably, the outer wall of the horizontal column is rotatably connected to the inner wall of the crossbar, the lower surface of the horizontal column is slidably connected to the upper surface of the positioning plate, a roller is fixedly connected to the lower surface of the positioning plate, the outer wall of the positioning plate is slidably connected to the inner wall of the outer shell, and the outer wall of the slider is slidably connected to the inner wall of the second U-shaped block.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the motor drives the rotating block to rotate, which drives the return frame to move left and right, thereby driving the crossbar and rack to move along the inner wall of the fixed shell. The movement of the rack causes the gear to rotate, which drives another rack to move along the outer wall of the limiting post, and finally drives the water sprayer to move left and right. This device achieves the effect of the water sprayer moving left and right back and forth, expanding the water spray coverage area.

[0015] 2. In this utility model, when the device is moved, the hydraulic cylinder is activated to push the slider to move under the restriction of the outer shell and the first U-shaped block, which drives the cross rod to rotate around the central column, causing the lower slider to move left and right. At the same time, it drives the fixed column to move down, driving the second U-shaped block and the positioning plate to move along the inner wall of the outer shell, causing the roller to move down to contact the ground. This device achieves the effect of adapting to the maintenance needs of different road conditions by switching between stable support and movement, thus improving the adaptability of the device.

Detailed Implementation

[0022] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a municipal road maintenance device, including a fixed shell 1, a motor 2 fixedly connected to the outer wall of the fixed shell 1, a rotating block 3 fixedly installed at the output end of the motor 2, a spiral frame 4 slidably connected to the outer wall of the rotating block 3, a crossbar 5 fixedly connected to the outer wall of the spiral frame 4, a rack 6 fixedly connected to the outer end of the crossbar 5, a rack 6 slidably connected to the inner wall of the fixed shell 1, a limit post 7 slidably connected to the inner wall of the rack 6, a limit post 7 fixedly connected to the outer wall of the fixed shell 1, a gear 8 meshingly connected to the outer wall of the rack 6, a gear 8 rotatably connected to the outer wall of the fixed shell 1, and a water spraying assembly installed on the inner wall of the fixed shell 1.

[0024] Specifically, the entire road surface is sprayed, and the motor 2 is turned on to drive the rotating block 3 to rotate. The rotation of the rotating block 3 causes the ring frame 4 to move left and right. The ring frame 4 acts as a limiter for the rotating block 3, so that the rotating block 3 will not deviate and damage the motor 2 when it rotates. The movement of the ring frame 4 causes the crossbar 5 to move. The movement of the crossbar 5 in turn causes the rack 6 to move on the inner wall of the fixed shell 1. The limiting post 7 acts as a limiter for the rack 6, so that the rack 6 will not deviate when it moves on the outer wall of the limiting post 7. In turn, the movement of the rack 6 drives the gear 8 to rotate on the inner wall of the fixed shell 1, ensuring the stable rotation of the gear 8.

[0025] Reference Figure 2 The water spray assembly includes a water tank 9, the lower surface of which is fixedly connected to the inner wall of the fixed shell 1, and a water pipe 10 is provided at the top of the water tank 9.

[0026] Specifically, the fixed shell 1 supports the gear 8 and the water tank 9, and guides and limits the water pipe 10 to ensure that the water pipe 10 is not damaged during the extension and retraction process.

[0027] Reference Figure 2 , Figure 3 and Figure 4 A water sprayer 11 is installed at one end of the water pipe 10. The outer wall of the water sprayer 11 is fixedly connected to the outer wall of the rack 6. The outer wall of the water sprayer 11 is slidably connected to the outer wall of the fixed shell 1. An outer shell 12 is fixedly connected to the lower surface of the fixed shell 1. A hydraulic cylinder 13 is fixedly connected to the outer wall of the outer shell 12. A slider 14 is fixedly installed at the output end of the hydraulic cylinder 13. A U-shaped block 15 is slidably connected to the outer wall of the slider 14. The upper surface of the slider 14 is slidably connected to the inner wall of the outer shell 12. A cross rod 16 is rotatably connected to the outer wall of the slider 14. A central column is rotatably connected to the inner wall of the cross rod 16. 17. A fixed column 18 is rotatably connected to the inner wall of the cross bar 16. A positioning plate 19 is fixedly connected to the lower surface of the fixed column 18. A U-shaped block 20 is fixedly connected to the upper surface of the positioning plate 19. A horizontal column 22 is slidably connected to the inner wall of the U-shaped block 20. The outer wall of the horizontal column 22 is rotatably connected to the inner wall of the cross bar 16. The lower surface of the horizontal column 22 is slidably connected to the upper surface of the positioning plate 19. A roller 21 is fixedly connected to the lower surface of the positioning plate 19. The outer wall of the positioning plate 19 is slidably connected to the inner wall of the outer shell 12. The outer wall of the slider 14 is slidably connected to the inner wall of the U-shaped block 20.

[0028] Specifically, the rack 6 moves, causing the water sprayer 11 to move on the outer wall of the fixed shell 1. The rack 6 supports the water sprayer 11, ensuring that the horizontal position of the water sprayer 11 is relatively fixed during the movement. The outer shell 12 supports the hydraulic cylinder 13. The hydraulic cylinder 13 pushes the slider 14 to slide on the inner wall of the U-shaped block 15. The U-shaped block 15 limits the slider 14, ensuring that the slider 14 will not deviate during the movement, thus protecting the hydraulic cylinder 13. The movement of the slider 14 causes the cross rod 16 to rotate, which in turn causes the cross rod 16 to move the horizontal column 22 on the outer wall of the U-shaped block 20. The U-shaped block 20 limits the horizontal column 22, ensuring that the position of the horizontal column 22 will not deviate during the movement. The movement of the horizontal column 22 causes the positioning plate 19 and the roller 21 to move downward. The outer shell 12 limits the positioning plate 19, ensuring the stability of the positioning plate 19 when it moves downward. The positioning plate 19 supports the roller 21, ensuring the stability of the roller 21 when it contacts the ground.

[0029] Working principle: When the motor 2 is turned on, the rotating block 3 rotates, which in turn moves the reciprocating frame 4 left and right. The movement of the reciprocating frame 4 moves the crossbar 5 and the rack 6 on the inner wall of the fixed shell 1. The rack 6 moves and the bottom gear 8 rotates. The rotation of the gear 8 causes the rack 6 above the bottom to move on the outer wall of the limiting post 7. The movement of the rack 6 drives the water sprayer 11 to move, so that the water sprayer 11 moves left and right. This device achieves the effect of the water sprayer 11 moving back and forth left and right, thus expanding the water spray coverage area.

[0030] When the device is moved, the hydraulic cylinder 13 is activated to push the slider 14 to move under the constraint of the outer shell 12 and the U-shaped block 15. The movement of the slider 14 causes the cross rod 16 to rotate on the outer wall of the central column 17, which in turn drives the lower slider 14 to move left and right. When the cross rod 16 rotates, it causes the fixed column 18 to move downward. The movement of the fixed column 18 causes the U-shaped block 20 and the positioning plate 19 to move on the inner wall of the outer shell 12. The movement of the positioning plate 19 causes the roller 21 to move downward. This device achieves the effect of adapting to the maintenance needs of different road conditions by switching between stable support and movement, thus improving the adaptability of the device.

[0031] This device not only achieves the effect of reciprocating the water sprayer 11 to expand the water spray coverage, but also achieves the effect of adapting to the maintenance needs of different road conditions through stable support and movement switching, thus improving the adaptability of the device.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
