Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of filling and compaction devices, specifically a dam filling and compaction device. Background Technology
[0002] In the construction of dam projects, various types of vibratory rollers or compactors are widely used for compacting soil and rock materials. Existing compaction equipment typically consists of a large roller body and a traction device. However, in practical applications, this type of equipment has some obvious limitations: "soft edges" easily form on both sides of the roller, causing the roller to compress and loosen at the edges. The horizontally positioned roller body cannot effectively compress the loose material at the edges, resulting in insufficient compaction and affecting the overall project quality. Utility Model Content
[0003] (a) Technical issues This utility model provides a dam filling and compaction device to solve the problem that the edge areas on both sides of the roller of the existing compaction equipment are prone to forming "soft edges" and the compaction is not in place.
[0004] (II) Technical Content To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a dam filling and compaction device, including a pressure roller body and a traction frame. The pressure roller body is rotatably disposed inside the traction frame, and the other end of the traction frame is connected to a traction device. Edge expansion compaction mechanisms are hinged at both ends of the traction frame and located outside the pressure roller body. An electric push rod for driving the edge expansion compaction mechanism to adjust its angle is hinged to each edge expansion compaction mechanism on the outside of the traction frame. The expansion compaction mechanism includes a U-shaped frame hinged to the outside of the traction frame, and an expansion pressure roller rotatably disposed inside the U-shaped frame. The piston end of the electric push rod is hinged to the upper end of the U-shaped frame. A scraper is fixedly disposed inside the traction frame and located in front of the pressure roller body by bolts. The cutting edge of the scraper is in contact with the outer surface of the pressure roller body. An adjustable counterweight box is fixed inside the traction frame, and the box contains counterweight blocks that can be added or removed.
[0005] Furthermore, the extended pressure roller is a cylindrical smooth roller, the width of which is / to / of the width of the pressure roller body.
[0006] Furthermore, the mounting plates at both ends of the scraper blade are provided with elongated holes and are connected to the traction frame by bolts to adjust the clamping force between the scraper blade and the pressure roller body.
[0007] Furthermore, the adjustable counterweight box is provided with a door for adding or removing counterweights.
[0008] Furthermore, in the horizontal state, the bottom surface of the extended pressure roller is flush with the lowest point of the pressure roller body.
[0009] (III) Technical Effects The advantages of this utility model compared with the prior art are as follows: 1. By hinged edge-extending compaction mechanisms at both ends of the traction frame and adjusting the angle using an electric push rod, extended pressure rollers can be used to specifically compact the edge areas on both sides of the pressure roller body. Specifically, in a horizontal state, the bottom surface of the extended pressure roller is flush with the lowest point of the pressure roller body, and its width is 1 / 5 to 1 / 3 of the pressure roller body. This effectively covers loose edge areas, avoiding the "soft edge" problem caused by the pressure roller body's inability to tightly hold edge material, as is common in traditional equipment. This ensures uniform compaction of the dam fill surface from the center to the edge, significantly improving the overall project quality.
[0010] 2. A scraper blade is installed inside the traction frame in front of the pressure roller body. Its cutting edge is in contact with the outer surface of the pressure roller, which can scrape away mud, stone debris and other debris that adhere to the pressure roller during its rolling process. The adjustable counterweight box fixed inside the traction frame can adjust the overall weight of the equipment by adding or removing internal counterweights, thereby improving construction efficiency and adaptability.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] Combined with appendix Figure 1 To be continued Figure 6 A dam filling and compaction device includes a pressure roller body 1 and a traction frame 2. The pressure roller body 1 is rotatably disposed inside the traction frame 2, and the other end of the traction frame is connected to a traction device. Edge expansion compaction mechanisms 3 are hinged at both ends of the traction frame 2 and located outside the pressure roller body 1. An electric push rod 4 for driving the edge expansion compaction mechanism 3 to adjust its angle is hinged to each edge expansion compaction mechanism 3 on the outside of the traction frame 2. The expansion compaction mechanism 3 includes a U-shaped frame 31 hinged to the outside of the traction frame 2, and an expansion pressure roller 32 rotatably disposed inside the U-shaped frame 31. The piston end of the electric push rod 4 is hinged to the upper end of the U-shaped frame 31. A scraper 5 is fixedly disposed inside the traction frame 2 and in front of the pressure roller body 1 by bolts. The cutting edge of the scraper 5 is in contact with the outer surface of the pressure roller body 1. An adjustable counterweight box 6 is fixedly disposed inside the traction frame 2, and the box contains counterweight blocks that can be added or removed.
[0022] In this embodiment, as a preferred technical solution, the extended pressure roller 32 is a cylindrical smooth roller with a width of 1 / 5 to 1 / 3 of the width of the pressure roller body 1. In the horizontal state, the bottom surface of the extended pressure roller 32 is flush with the lowest point of the pressure roller body 1.
[0023] In this embodiment, as a preferred technical solution, the mounting plates at both ends of the scraper blade 5 are provided with elongated holes and are connected to the traction frame 2 by bolts to realize the adjustment of the clamping force between the scraper blade 5 and the pressure roller body 1.
[0024] In this embodiment, as a preferred technical solution, the adjustable counterweight box 6 is provided with a door 61 for adding or removing counterweight blocks.
[0025] The working principle of this utility model is as follows: 1. First, according to the particle size and compaction thickness requirements of the soil and rock materials in the dam filling area, add or remove counterweights into the adjustable counterweight box 6 to adjust the overall weight of the equipment to match the required compaction strength; then fix the traction frame 2 to the external traction equipment (such as an engineering tractor).
[0026] 2. After the traction equipment is started, it drives the traction frame 2 and the pressure roller body 1 to move forward. The pressure roller body 1 rolls on the soil and stone material of the filling surface and uses its own weight to perform core compaction of the soil and stone material.
[0027] 3. For areas on both sides of the pressure roller body 1 where "soft edges" are easily formed, the angle of the U-shaped frame 31 connected to its piston end is adjusted by controlling the electric push rod 4: when it is necessary to compact the loose material at the edge, the electric push rod 4 pushes the U-shaped frame 31 to rotate downward, so that the extended pressure roller 32, which is rotated inside the U-shaped frame 31, fits against the edge filling surface. The extended pressure roller 32 and the pressure roller body 1 roll synchronously to compact the edge area in a targeted manner and prevent the material from becoming loose.
[0028] 4. During the rolling and compaction process of the pressure roller body 1, the blade of the scraper 5 is always in contact with the outer surface of the pressure roller body 1 to scrape away the mud, stone debris and other impurities adhering to the surface of the pressure roller in real time.
[0029] 5. During the entire compaction process, the angle of the extended pressure roller 32 can be dynamically adjusted by the electric push rod 4 and the weight of the equipment can be adjusted by the adjustable counterweight box 6, so that the pressure roller body 1 and the extended pressure roller 32 work together to achieve continuous and uniform compaction from the center to the edge of the filling surface.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
