These machines typically use a single compaction wheel, whose weight and compaction effect cannot be flexibly adjusted, resulting in poor adaptability to different types of dam filling environments. Furthermore, traditional compaction machinery often fails to achieve ideal compaction results when dealing with complex terrain and varying soil conditions, easily leading to dam structural instability and affecting project quality and safety. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compaction auxiliary device for dam body filling in water conservancy projects, comprising a mobile frame, a main compaction wheel, and a secondary compaction wheel. The mobile frame has an opening 1 on its inner side. The main compaction wheel is located in the middle of the opening 1, and a central shaft runs through the center of the main compaction wheel. The two ends of the central shaft are connected to the inner walls of both sides of the opening 1 via bearings. The main compaction wheel contains, sequentially, water tanks 1, 2, 3, and 4, each with uniformly alternating reinforcing inner columns. An opening 2 is also provided on the mobile frame on one side of the opening 1. A crossbeam is also provided on the mobile frame above the opening 2. A U-shaped frame is provided below the crossbeam via a shock-absorbing component.

[0012] Compared with existing technologies, this utility model, "A compaction auxiliary device for dam body filling in water conservancy projects," has significant technical advantages and positive effects, specifically reflected in the following aspects:

[0013] 1. Precise weight adjustment capability:

[0014] The core design of this invention lies in the main compaction roller's bucket-like structure, incorporating multiple independent water chambers. Each chamber can be independently filled and drained, allowing for precise control of the water volume and thus enabling fine-tuning of the roller's weight. This design overcomes the limitations of existing technologies where the compaction roller's weight is fixed and its adjustment range is limited. This allows the device to adapt to the needs of different dam construction environments, ensuring structural stability and durability during compaction. Precise weight adjustment not only improves compaction efficiency but also reduces repetitive work due to unsuitable weight, thereby increasing construction efficiency.

[0015] 2. Enhanced soil compaction effect:

[0016] This invention features a vibratory motor mounted on the top of the U-shaped frame of the auxiliary compaction roller. Through controllable vibration frequency and amplitude, it significantly improves soil compaction. The vibratory motor causes soil particles to rearrange during vibration, expelling air and moisture, thereby enhancing soil density and stability. Compared to traditional compaction methods, this device achieves higher compaction results with the same number of compaction passes, reducing the number of passes and construction time, and lowering construction costs.

[0017] 3. Improve construction efficiency and safety:

[0018] Because this device enables precise weight adjustment and efficient soil compaction, frequent equipment replacement or adjustment is unnecessary during construction, reducing equipment change and debugging time and improving construction efficiency. Simultaneously, the use of a vibratory motor makes the compaction process smoother, reducing the risk of dam structural instability caused by uneven compaction and improving construction safety.

[0019] 4. Enhanced applicability and flexibility:

[0020] This invention features a flexible design, making it suitable for various dam filling environments. Whether it's a clay dam, a concrete dam, or an earth-rock dam, ideal compaction results can be achieved by adjusting the water volume of the main compactor wheel and the vibration parameters of the auxiliary compactor wheel. This wide applicability makes this device highly flexible and practical in actual engineering applications.

[0021] 5. Significant environmental protection and energy-saving effects:

[0022] This device reduces energy consumption and material waste during construction through precise adjustment and efficient compaction. Precise weight adjustment avoids resource waste caused by excessive rolling, while the efficient compaction by the vibratory motor reduces the number of rolling passes, lowering the frequency of equipment use and energy consumption, thus meeting the requirements of green construction and energy conservation and emission reduction.

[0023] 6. Improved structural stability and durability:

[0024] The multi-layered independent water tank design of the main compaction wheel not only achieves weight adjustment but also improves the overall stability and durability of the device through a reasonable structural layout and material selection. The independent design of each water tank avoids the risk of overall failure due to damage to a single water tank, thus extending the service life of the device.

[0025] In summary, this utility model, "A compaction auxiliary device for dam body filling in water conservancy projects," significantly improves compaction effect, construction efficiency, and safety through innovative design concepts and advanced technical means, enhances applicability and flexibility, and also has significant environmental protection and energy-saving effects, providing an efficient and reliable technical solution for dam body filling in water conservancy projects.

[0034] like Figure 1 As shown, the overall structure of the mobile frame 2 is made of high-strength steel to ensure its stability and durability during use. A traction block 1 is located at the middle of one end of the mobile frame 2, and this traction block 1 is fixed to the mobile frame 2 by welding or bolting. The design of the traction block 1 enables it to withstand large traction forces, ensuring that the mobile frame 2 will not fall off or be damaged during dragging.

[0035] The towing block 1 is equipped with a towing hole, the diameter and shape of which are designed according to the connection device of the external trailer equipment to ensure a smooth connection. The inner wall of the towing hole is specially treated, such as by adding a wear-resistant coating, to extend its service life. The towing block 1 is made of high-strength alloy steel to ensure that it is not easily deformed or broken during long-term use.

[0036] An opening 3 is provided on the inner side of the movable frame 2. The size and shape of the opening 3 are designed according to the size of the main roller 4 to ensure that the main roller 4 can be installed and operated smoothly. The edges of the opening 3 are smoothed to prevent damage to the main roller 4 during use.

[0037] The main rolling roller 4 is located in the middle of the opening 3. The main rolling roller 4 is made of high-strength rubber or polyurethane material to ensure good elasticity and wear resistance during rolling. A central shaft 9 is passed through the center of the main rolling roller 4. The central shaft 9 is made of high-strength stainless steel to ensure that it is not easily bent or broken during long-term use.

[0038] Both ends of the central shaft 9 are connected to the inner walls of the opening 3 via bearings 10. The bearings 10 are high-precision rolling bearings to ensure that the main rolling roller 4 has low frictional resistance and high rotational accuracy during operation. The outer ring of the bearing 10 is fixed to the inner wall of the opening 3 by bolts or clamping devices, while the inner ring is tightly fitted with the central shaft 9 to ensure that it will not loosen or fall off during operation.

[0039] The main rolling roller 4 has water tank 1 5, water tank 2 6, water tank 3 7 and water tank 4 8 arranged sequentially inside. Reinforcing inner columns 21 are evenly and alternately arranged inside the water tank 1 5, water tank 2 6, water tank 3 7 and water tank 4 8. The water tank 1 5, water tank 2 6, water tank 3 7 and water tank 4 8 are arranged in a ring from the outside to the inside.

[0040] Both ends of the main roller 4 are provided with grooves 20. One of the grooves 20 has a strip groove 22 inside. Water inlets 19 are arranged side by side inside the strip groove 22. Each water inlet 19 is detachably provided with a sealing cap.

[0041] Each water inlet 19 corresponds one-to-one with water tank 1 5, water tank 2 6, water tank 3 7, and water tank 4 8.

[0042] Main rolling roller 4: As the core component of the entire device, the main rolling roller 4 is cylindrical in shape with a smooth surface, making it suitable for rolling operations.

[0043] Water tank 5: Located on the outermost side of the main roller 4, it is arranged in a ring.

[0044] Water tank 2 6: Located inside water tank 1 5, it is also arranged in a ring.

[0045] Water tank 3 7: Located inside water tank 2 6, it continues to be arranged in a ring.

[0046] Water tank 48: Located inside water tank 37, the innermost annular water tank.

[0047] Each water tank (water tank 1, water tank 2, water tank 3, water tank 4, water tank 8) has reinforced inner columns 21 evenly and alternately arranged inside. The function of these reinforced inner columns 21 is to enhance the structural strength of the water tank and prevent deformation under high pressure water.

[0048] Water inlet 19: Multiple water inlets 19 are arranged side by side inside the strip groove 22, and each water inlet 19 is equipped with a detachable sealing cap. The number of water inlets 19 corresponds to the number of water tanks, that is, each water inlet 19 corresponds to water tank 1 5, water tank 2 6, water tank 3 7 and water tank 4 8 respectively.

[0049] Water Injection Process: When water needs to be injected into the water tanks, first open the sealing cap on each water inlet 19. Water is then injected into water tanks 1-5, 2-6, 3-7, and 4-8 through the water inlets 19. Since each water inlet 19 corresponds to a specific water tank, water is evenly distributed throughout the tanks. The reinforcing inner columns 21 inside the water tanks play a crucial role in the water injection process. They not only enhance the structural strength of the water tanks but also prevent deformation under high-pressure water, ensuring the overall stability of the main compaction wheel 4. When the water tanks are full, the overall weight of the main compaction wheel 4 increases, enhancing the compaction effect.

[0050] An opening 13 is also provided on the movable frame 2 on one side of the opening 13. A crossbeam frame 11 is also provided on the movable frame 2 above the opening 13. A U-shaped frame 14 is provided below the crossbeam frame 11 via a shock-absorbing component 12. The shock-absorbing component 12 includes two mounting plates 1203 connected to the crossbeam frame 11 and the U-shaped frame 14. Two rigid springs 1201 are arranged side by side between the two mounting plates 1203. Damping rubber columns 1202 are fixed between the two mounting plates 1203 inside the two rigid springs 1201. A vibration motor 16 is installed in the middle of the top of the U-shaped frame 14, and a secondary rolling wheel 15 is provided on the inner side of the U-shaped frame 14.

[0051] The main roller 4 and the auxiliary roller 15 are of equal length.

[0052] The inner walls on both sides of the opening 13 are provided with sliding grooves 18, and the outer walls on both sides of the U-shaped frame 14 are provided with sliders 17 extending into the inner side of the sliding grooves 18.

[0053] The function of the crossbeam frame 11 is to support the structure below it, ensuring the stability and strength of the overall device. A U-shaped frame 14 is connected to the bottom of the crossbeam frame 11 via a vibration damping assembly 12. The vibration damping assembly 12 is designed to reduce vibration and impact, improving the service life and stability of the device.

[0054] The specific structure of the vibration damping assembly 12 is as follows: it includes two mounting plates 1203 connected to the crossbeam frame 11 and the U-shaped frame 14. Two rigid springs 1201 are arranged side-by-side between the two mounting plates 1203. The main function of the rigid springs 1201 is to provide elastic support and absorb and buffer vibrations. Damping rubber posts 1202 are fixed between the two mounting plates 1203 on the inner sides of the two rigid springs 1201. The function of the damping rubber posts 1202 is to further reduce vibration, provide a damping effect, and ensure the stability of the device during operation.

[0055] A vibratory motor 16 is installed at the top center of the U-shaped frame 14. The function of the vibratory motor 16 is to generate vibration, making the material more uniform and efficient during processing. A secondary compaction roller 15 is provided on the inner side of the U-shaped frame 14. The secondary compaction roller 15 is designed to assist the main compaction roller 4 in compacting and processing the material.

[0056] It is worth noting that the main roller 4 and the auxiliary roller 15 are of equal length. This design ensures the uniformity and consistency of the material during the rolling process and improves the rolling effect.

[0057] The inner walls on both sides of opening 13 are provided with grooves 18. The main function of the grooves 18 is to provide a sliding channel for the slider 17, ensuring the stability and accuracy of the slider 17 during movement. The outer walls on both sides of the U-shaped frame 14 are provided with sliders 17 extending into the inner side of the grooves 18. The function of the sliders 17 is to connect the U-shaped frame 14 and the grooves 18, allowing the U-shaped frame 14 to move smoothly within the grooves 18.

[0058] In this embodiment, the connecting device of the external trailer equipment is first inserted into the traction hole of the traction block 1 and fixed by the locking device to ensure that the moving frame 2 is firmly connected to the trailer equipment. Then, the trailer equipment is started, and the moving frame 2 is moved by the traction block 1. When the moving frame 2 reaches the predetermined position, water is injected into the water tanks 5, 6, 7, and 8 through the water inlet 19 as needed. Since the volumes of the water tanks are known, it is easy to control the overall weight of the main compaction wheel 4. The external trailer is started, pulling the moving frame 2 forward, causing the main compaction wheel 4 to rotate in the opening 3, thereby compacting the ground. The rotation is achieved through the cooperation of the central shaft 9 and the bearing 10, ensuring smooth and efficient operation during compaction. When the vibratory motor 16 is started, due to the setting of the shock absorption component 12, the entire crossbeam frame 11 and the moving frame 2 can maintain relative stability during the operation of the vibratory motor 16. Under the action of the vibratory motor 16, the U-shaped frame 14 drives the auxiliary compaction wheel 15 to further compact the road surface, thereby enhancing the soil density and stability, achieving a higher compaction effect, reducing the number of compaction cycles and construction time, and reducing construction costs.
