Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically to a rammer for road leveling. Background Technology

[0002] In infrastructure construction such as buildings, roads, and water conservancy, soil compaction is a crucial step in ensuring project quality. As a commonly used compaction device, the performance of rammers directly affects the compaction effect and project progress. With the acceleration of urbanization, various construction projects have increasingly stringent requirements for site leveling and foundation compaction. In urban infrastructure construction, different regions have significantly different requirements for foundation bearing capacity.

[0003] As a core piece of equipment for soil compaction in engineering construction, the rammer acts on the soil through mechanical force or vibration energy, changing the soil particle structure and density, and providing stable foundation support for various infrastructures. Its role runs through the entire construction process in multiple fields such as building, road and water conservancy.

[0004] When using existing rammers, the centrifugal rotation of the eccentric wheel drives the rammer plate to vibrate and level the land, which facilitates the uniform leveling of the land. However, the length of the eccentric wheel is fixed when dealing with different soil types, which makes it inconvenient for workers to adjust the length of the eccentric wheel according to the soil type. This can easily affect the compaction effect of the soil, the uniform leveling effect of the soil, and consequently the adaptability and construction efficiency of the rammer. Utility Model Content

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3As shown, this utility model is a tamping machine for road leveling, including a plate body 1. Two symmetrical support frames 2 are provided at one end of the plate body 1. One end of the plate body 1 is arc-shaped. A rotating column 3 is rotatably connected to the support frame 2. Two symmetrical eccentric wheels 4 are provided on one side of the rotating column 3. An adjustment mechanism is provided between the eccentric wheels 4 and the plate body 1 to adjust the length of the eccentric wheels 4 according to the soil type. The adjustment mechanism includes two symmetrical fixed plates 5 fixed to the rotating column 3. The rotating column 3 passes through the fixed plates 5. A hydraulic telescopic rod 6 is fixed inside one of the fixed plates 5. The telescopic end of the hydraulic telescopic rod 6 extends out of the fixed plate 5 and is fixedly connected to the eccentric wheel 4. A limiting component is provided between the eccentric wheel 4 and the fixed plate 5. The limiting component includes a limiting telescopic plate 8 fixed inside the other fixed plate 5. The limiting telescopic plate 8 extends out of the fixed plate 5 and is fixedly connected to the eccentric wheel 4. A connecting plate 7 is fixed between the two eccentric wheels 4. A limiting element is provided between the support frame 2 and the plate body 1. The limiting components include two symmetrical limiting telescopic columns 9 hinged to the plate 1. The upper end of the limiting telescopic columns 9 is hinged to the support frame 2. Springs 10 are sleeved on the limiting telescopic columns 9, and the ends of the springs 10 are hinged to the support frame 2 and the plate 1. The motor 18 is a variable frequency motor 18. A controller 19 is fixed on one side of the plate 1, and the controller 19 is electrically connected to the motor 18.

[0026] Specifically, workers transport the slab 1 to the road surface requiring leveling. The vibration generated by the centrifugal rotation of the eccentric wheel 4 causes the support frame 2 to level the road. When the length of the eccentric wheel 4 needs adjustment, the hydraulic telescopic rod 6 is operated, causing the eccentric wheel 4 to move, which in turn moves the connecting plate 7 and extends / retracts the limiting telescopic plate 8, thus restricting the eccentric wheel 4. This allows workers to adjust the length of the eccentric wheel 4 according to the type of road soil, adjusting the leveling force and improving the adaptability of the rammer. Simultaneously, the support frame 2 rotates, causing the limiting telescopic column 9 to extend and retract, and the spring 10 to extend and retract. When the eccentric wheel 4 raises the support frame 2 to its maximum angle, the spring force of the spring 10 applies force to the support frame 2, promoting soil leveling and adjusting the falling rhythm for uniform compaction. The controller 19 adjusts the rotation speed of the motor 18 to regulate the striking rhythm of the support frame 2, further facilitating road leveling. The adjustment mechanism allows workers to adjust the length of the eccentric wheel 4 according to the type of road soil, improving the adaptability of the rammer, ensuring uniform road leveling, and minimizing the impact on construction efficiency.

[0027] In this embodiment, refer to Figure 1 - Figure 2As shown, a water tank 11 is fixed on the plate 1, and a cover plate 12 is hinged to the water tank 11. A water pump 14 is installed on one side of the water tank 11, and the water pump 14's suction end is fixedly connected to the water tank 11. A fixed pipe 13 is fixedly connected to the water pump 14's outlet end. Two symmetrical connecting pipes 15 are fixed to one side of the fixed pipe 13. A nozzle 16 is fixed to the end of the connecting pipe 15 away from the fixed pipe 13. The nozzle 16 is trumpet-shaped and corresponds to the support frame 2. Two symmetrical support rods 17 are fixed on the plate 1, and the support rods 17 are fixedly connected to the connecting pipes 15.

[0028] Specifically, the staff opens the cover plate 12 and adds an appropriate amount of water to the water tank 11. They then operate the water pump 14, which draws water from the water tank 11 through the pump's suction end and enters the fixed pipe 13 through the outlet end. The water then enters the two connecting pipes 15 and is sprayed out through the nozzle 16 to remove dust from the road during leveling, reducing dust scattering and pollution. The nozzle 16 is connected to the horn pipe to increase the spraying range of the nozzle 16. Together with the support frame 2, it facilitates the leveling of the road and improves the leveling effect.

[0029] In this embodiment, refer to Figure 3 - Figure 4 As shown, a motor 18 is fixed on the plate 1, and a transmission column 20 is rotatably connected to the plate 1. One end of the transmission column 20 and the output end of the motor 18 are both fixed with pulleys. The two pulleys are connected by a transmission belt. The transmission column 20 is rotatably connected to the support frame 2. The transmission column 20 and the rotating column 3 are connected by two transmission belts. A flat plate is fixed at the lower end of the support frame 2.

[0030] An inclined limiting frame 21 is fixed to one end of the plate 1 away from the eccentric wheel 4. A handle 22 is slidably mounted on the limiting frame 21, and the handle 22 is fixed to the limiting frame 21 by bolts.

[0031] Specifically, the workers connect the rammer to an external circuit. During rammering, the motor 18 is turned on. The motor 18 drives the transmission column 20 to rotate via the first transmission belt. The transmission column 20 drives the rotating column 3 to rotate via the second transmission belt, which in turn drives the eccentric wheel 4 to rotate. This causes the support frame 2 to rotate on the transmission column 20, allowing the leveling plate to vibrate and level the road. The curved shape of one end of the plate body 1 enhances the leveling effect. Then, the bolts on the limiting frame 21 are tightened, allowing the handle 22 to slide within the limiting frame 21. The handle is then fixed in place by the bolts to accommodate operators of different heights, facilitating the leveling of the road.

[0032] The working principle of this utility model is as follows: The rammer is transported to the designated location, and the staff connects to the rammer through an external circuit. During rammering, the motor 18 is operated. The motor 18 causes the transmission column 20 to rotate through the first transmission belt. The transmission column 20 causes the rotating column 3 to rotate through the second transmission belt, which in turn causes the eccentric wheel 4 to rotate. This drives the support frame 2 to rotate on the transmission column 20, so that the leveling plate vibrates and levels the road. The fact that one end of the plate 1 is arc-shaped improves the leveling effect on the road.

[0033] Then, when it is necessary to adjust the length of the eccentric wheel 4, the hydraulic telescopic rod 6 is operated, causing the eccentric wheel 4 to move, the connecting plate 7 to move, and the limiting telescopic plate 8 to extend and retract, thus restricting the eccentric wheel 4. This allows the staff to adjust the length of the eccentric wheel 4 according to the type of road soil, adjust the leveling force on the road, and improve the adaptability of the tamping machine. At the same time, the support frame 2 rotates, causing the limiting telescopic column 9 to extend and retract, and the spring 10 to extend and retract. When the eccentric wheel 4 raises the support frame 2 to its maximum angle, the elastic force of the spring 10 causes the support frame 2 to be stressed, promoting the leveling of the soil, adjusting the falling rhythm, and facilitating the uniformity of the compaction. The rotation speed of the motor 18 is adjusted by the controller 19, which facilitates the adjustment of the striking rhythm of the support frame 2.

[0034] Then, the staff opened the cover plate 12 and added an appropriate amount of water into the water tank 11. They then operated the water pump 14, which drew water from the water tank 11 through the pump's suction end and into the fixed pipe 13 through the outlet end. The water then entered the two connecting pipes 15 and was sprayed out through the nozzles 16 to remove dust from the smooth road surface, reducing dust scattering and pollution. The nozzles 16 also served as a horn pipe to increase the spraying range of the nozzles 16. Together with the support frame 2, this facilitated the smoothing of the road surface and improved the smoothing effect.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
