Description

Technical Field

[0001] This utility model relates to the field of road paving technology, specifically a road paving device for municipal engineering construction. Background Technology

[0002] Municipal roads refer to roads within a city that are used by vehicles and pedestrians and have certain technical conditions and facilities. They are an important part of urban infrastructure. The construction of municipal roads can improve urban functions, optimize urban spatial layout, and promote the effective functioning of the city as a whole. In the construction of long-distance, multi-segment roads, it is often necessary to use paving devices to level the road surface to improve the speed of road construction and the appearance of the road.

[0003] An investigation revealed that Chinese utility model patent CN218090374U discloses a ground paving device for municipal road construction, comprising two bases and a movable box. Four first fixing plates are fixedly welded to the bottom side of the movable box, and a common rotating shaft is rotatably arranged between corresponding pairs of first fixing plates. Two rollers are fixedly sleeved on the rotating shaft, and the rollers roll with their corresponding bases. This utility model has a reasonable design, effectively removing air bubbles from concrete during ground paving, reducing gaps between concrete particles, ensuring the quality of the paved concrete, and providing good performance.

[0004] Although the aforementioned patent utilizes components such as a moving box and base, and employs rollers to move the moving box, and through the coordination of a vibrating motor, rake, paving roller, and servo motor, the continuous vibration of the rake within the concrete can expel air bubbles during concrete pouring and improve the smoothness of the concrete surface, the small size of the rake results in a small contact area with the concrete. If the concrete needs to be made denser through vibration, repeated vibration is required. However, due to the characteristics of concrete materials, repeated vibration is prone to segregation, which is not conducive to improving the overall strength of the concrete. At the same time, the small contact area is also not conducive to improving the efficiency of road paving.

[0005] Therefore, this utility model provides a road paving device for municipal engineering construction to solve the above problems. Utility Model Content

[0018] (III) Beneficial Effects

[0019] By setting up a leveling component, concrete pavement can be vibrated quickly and efficiently, improving concrete density, reducing air bubbles during concrete pouring, and improving the appearance quality of the concrete. Utilizing the cooperation of a vibrating motor, sliding rod, sliding plate, abutment rod, and blades, the high-speed rotation of the vibrating motor drives the abutment rod to slide continuously inside the sliding sleeve. During retraction, the blades rotate in conjunction with the motor and are then limited by the limit seat, reducing the contact area during withdrawal. When released, the blades expand the material properties of the compressed spring, thereby increasing the contact area with the concrete and improving the effect of a single vibration. This avoids prolonged vibration in the same spot, which can cause segregation in the concrete. Through continuous cyclic vibration, air bubbles in the concrete are eliminated, improving the strength of the concrete pavement. Attached Figure Description

[0027] 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.

[0028] This utility model provides a paving device for municipal engineering road construction, such as... Figures 1-5 As shown, the municipal engineering road construction paving device includes a paving machine 1, a drive roller 2 is fixedly connected to the bottom end of the paving machine 1, a drive wheel 3 is rotatably connected to the side wall of the drive roller 2, and a paving component is provided at the bottom end of the paving machine 1.

[0029] The paving assembly includes a vibrating motor 4 fixedly connected to the bottom of the paving machine 1. A slide rod 5 is fixedly connected to the bottom of the paving machine 1. A slide plate 6 is slidably connected to the outer wall of the slide rod 5. The output end of the vibrating motor 4 is fixedly connected to the top of the slide plate 6. A support plate 7 is fixedly connected to the end of the slide rod 5. A sliding sleeve 8 is fixedly connected to the inner wall of the support plate 7. A stop rod 9 is slidably connected to the inner wall of the sliding sleeve 8. A rotating shaft 10 is fixedly connected to the bottom of the stop rod 9. A blade 11 is rotatably connected to the outer wall of the rotating shaft 10. A limit seat 12 is fixedly connected to the bottom of the sliding sleeve 8. A compression spring is fixedly connected to the top of the blade 11.

[0030] A drive motor 13 is fixedly connected to the inner bottom end of the paving machine 1, and a cam 14 is fixedly sleeved on the output end of the drive motor 13.

[0031] A sliding rod 15 is slidably connected to the side wall of the leveling machine 1, and a screw 16 is threadedly connected to the inner wall of the sliding rod 15. A cam 14 abuts against the lower end of the sliding rod 15, and a rotating seat 17 is fixedly connected to the lower end of the screw 16. A leveling roller 18 is rotatably connected to the inner wall of the rotating seat 17.

[0032] Specifically, by setting a drive roller 2 and a drive wheel 3 at the bottom of the paving machine 1, the paving machine 1 can move more easily, improving the work of long-line paving. Using the paving components, high-speed vibration can improve the density of concrete, reduce the air bubble rate generated during concrete pouring, and improve the appearance of the concrete pavement. By starting the vibration motor 4, the slide plate 6, which is fixedly connected to its output end, continuously moves longitudinally against the outer wall of the slide rod 5, and continuously abuts against the abutment rod 9, causing the abutment rod 9 to continuously slide longitudinally inside the sliding sleeve 8. Since the bottom end of the abutment rod 9 is fixedly connected to a rotating shaft 10, and the outer wall of the rotating shaft 10 is rotatably connected to a blade 11, the upper top of the blade 11 is connected to the support plate 7 through a compression spring. Therefore, the blade 11 will move synchronously with the upward movement of the abutment rod 9. However, since the bottom end of the sliding sleeve 8 is fixedly connected to a limiting seat 12, when the blade 11 moves upward, it will be limited by the limiting seat 12, thus retracting inward and reducing contact with the concrete. When the abutment rod 9 moves downward, the blade 11 leaves the limit seat 12 and reopens under the tension of the compression spring, making contact with the concrete during downward pressure, increasing the contact area and enhancing the vibration effect. Through continuous cyclic vibration, air bubbles generated during concrete pouring are eliminated, improving the durability of the concrete. The drive motor 13 is then activated, and the cam 14 at the output end of the drive motor 13 continuously abuts against the sliding rod 15, causing the sliding rod 15 to move longitudinally along the side wall of the paving machine 1. This drives the leveling roller 18 on the inner wall of the rotating seat 17 to continuously flatten the concrete surface. The smooth outer wall of the leveling roller 18 can be used to flatten and smooth the air bubbles that have risen to the concrete surface due to vibration. When the concrete pavement height is different, the screw 16 can be rotated to drive the rotating seat 17 to rise or fall to conform to the concrete pavement. This component has a simple structure, is highly practical, and can effectively reduce air bubbles generated during concrete pouring, improving the efficiency of concrete paving.

[0033] A water tank 19 is fixedly connected to the side wall of the paving machine 1. A water outlet seat 20 is slidably connected to the bottom end of the water tank 19. A nozzle is rotatably connected to the bottom end of the water outlet seat 20.

[0034] The paving machine 1 has bases 21 on both sides, and soil-breaking cones are fixedly connected to the side walls of the bases 21. A hydraulic seat 22 is fixedly connected to the top of the bases 21.

[0035] The upper top of the hydraulic base 22 is fixedly connected to the rail 23, and the end of the hydraulic base 22 is fixedly connected to the oil inlet.

[0036] An operation panel 24 is fixedly connected to the side wall of the paving machine 1, and a heat dissipation fin is fixedly connected to the top of the paving machine 1.

[0037] Specifically, after the paving is completed, the blades 11 and the leveling rollers 18 can be cleaned with water in the water tank 19 to avoid the concrete drying out and becoming difficult to clean. When encountering road surfaces of different heights, the height of the track 23 can be adjusted by the hydraulic seat 22 at the top of the base 21, which facilitates the movement of the drive wheels 3.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
