Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering construction technology, and in particular, it is a compaction auxiliary device for dam body filling in water conservancy projects. Background Technology

[0002] In the construction of water conservancy projects, dam filling is a crucial step in ensuring the stability of the engineering structure and its flood control capabilities. To improve the density and bearing capacity of the fill soil layer, a compaction vehicle typically drives a compaction wheel to repeatedly compact the fill material. Existing compaction equipment generally consists of a vehicle body, an extension beam, and a compaction wheel, achieving the compaction of the dam body through gravity and rolling action during construction.

[0003] However, in actual operation, due to the complex environment of the construction site, soil particles, dust and other impurities easily adhere to the surface of the compaction wheel. As the operation time increases, these deposits gradually accumulate and affect the compaction effect, leading to uneven compaction and reduced construction quality. To solve this problem, some equipment has attempted to install simple scrapers to remove the deposits, but due to the lack of an effective collection structure, the cleaned dust particles are easily scattered again, causing secondary pollution or equipment wear, resulting in low cleaning efficiency and high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a compaction auxiliary device for dam construction in water conservancy projects, so as to solve the problems mentioned in the background art.

[0005] 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, which is installed on the compaction vehicle body and has a compaction wheel installed at the forward end of the compaction vehicle body through a beam; the beam is a U-shaped extension beam.

[0006] An impurity collection and cleaning component is provided on the upper side of the side of the roller facing away from the roller body for scraping and collecting dust particles attached to the surface of the roller.

[0007] The impurity collection and cleaning assembly includes a scraping tongue that rubs against the outer wall of the rolling wheel, and an attachment collection box that communicates with the scraping tongue.

[0008] Both the scraping tongue and the attachment collection box are mounted on the U-shaped extension beam.

[0009] In a preferred embodiment, the attachment collection box has a collection chamber on the side facing the rolling wheel; the bottom surface of the attachment collection box and the end closest to the rolling wheel are integrally formed with an arc-shaped slope that matches the shape of the rolling wheel and has a gap with the rolling wheel.

[0010] In this preferred embodiment, the scraping tongue is integrally connected with the attachment collection box, and the scraping tongue extends from the attachment collection box.

[0011] In this preferred embodiment, the scraping tongue plate specifically makes frictional contact with the outer wall of the rolling wheel through its sharp scraping end;

[0012] The sharp scraping end is located at the end of the scraping tongue that is away from the attachment collection box, and is integrally connected to the scraping tongue.

[0013] In this preferred embodiment, the sharp scraping end and the back of the scraping tongue plate are in frictional contact with the outer wall of the rolling wheel.

[0014] In this preferred embodiment, both ends of the scraping tongue are integrally connected to the outer wall of the attachment collection box, and the two side baffles are integrally connected to the two ends of the sharp scraping end.

[0015] In this preferred embodiment, a support frame plate is bolted to the inner wall of the end of the U-shaped extension beam away from the compaction vehicle body, and an installation space for installing an attachment collection box is formed between the top of the support frame plate and the compaction wheel.

[0016] In this preferred embodiment, the attachment collection box fits into the installation space, and both sides of the U-shaped extension beam are fixedly connected to the attachment collection box by locking pins, so that the attachment collection box is fixed in the installation space.

[0017] In a preferred embodiment of this design, the top surface of the attachment collection box is fitted with a handle.

[0018] In this preferred embodiment, the outer walls of both sides of the attachment collection box are provided with pin holes for locking pin connection.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0020] This compaction auxiliary device for dam filling in water conservancy projects has a debris collection and cleaning component located on the upper side of the compaction wheel facing away from the compaction vehicle. The bottom of the attachment collection box, near the compaction wheel, has an integrally formed arc-shaped slope. This slope makes frictional contact with the outer wall of the compaction wheel. When the compaction wheel rolls in the U-shaped extension beam, the dust particles attached to its outer wall are scraped off by the attachment collection box and guided to fall into the collection box by the arc-shaped slope. This avoids the problem of uneven compaction caused by dust and soil adhesion in traditional compaction equipment during continuous operation, reduces the frequency of manual periodic shutdowns to clean the compaction wheel, and improves the overall construction efficiency. The collected dust particles can be uniformly disposed of to avoid polluting the construction site environment. This device achieves automatic scraping and collection of dust particles on the surface of the compaction wheel, improving construction efficiency.

[0021] The curved slope design conforms to the curvature of the roller's outer wall, making scraping more thorough. The collection chamber is located inside the attachment collection box, which can effectively hold the scraped dust particles and prevent secondary pollution. The entire cleaning process is synchronized with the rolling of the roller, requiring no additional power drive, making it energy-efficient. The roller is always kept clean, ensuring that each roll is uniform and powerful, which helps to improve the consistency of the dam's compaction density, thereby improving the quality of the project.

Detailed Implementation

[0033] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0034] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0035] This embodiment provides, for example Figures 1 to 8 The illustrated compaction auxiliary device for dam construction in a water conservancy project includes a dam body 1 constructed at the dam site. A compaction vehicle 2 is mounted on the dam body 1. A U-shaped extension beam 6 is provided at the forward end of the compaction vehicle 2. A compaction wheel 3 is rotatably mounted within the U-shaped extension beam 6. An impurity collection and cleaning component 5 is located above the side of the compaction wheel 3 facing away from the compaction vehicle 2. This component scrapes away dust particles adhering to the surface of the compaction wheel 3 after compacting the dam body and collects these adhering dust particles. The impurity collection and cleaning component 5 includes components related to the compaction vehicle 2. The attachment collection box 4 is in frictional contact with the outer wall of the roller 3, and the collection chamber 13 is provided on the side of the attachment collection box 4 facing the roller 3. The bottom surface of the attachment collection box 4 and the end near the roller 3 are integrally formed with an arc-shaped slope 11. The arc-shaped slope 11 is in frictional contact with the outer wall of the roller 3. When the roller 3 advances and rolls in the U-shaped extension beam 6 to compact the filling dam body 1, the dust particles attached to the outer wall of the roller 3 are scraped off by the attachment collection box 4 and fall into the collection chamber 13, thereby cleaning the dust particles on the outer wall of the roller 3 and collecting these dust particles.

[0036] In this embodiment, a scraping tongue 14 is integrally connected to one side of the collection chamber 13 and the end of the attachment collection box 4 near the rolling wheel 3. The scraping tongue 14 extends from the attachment collection box 4 and is responsible for receiving dust particles that slide into the collection chamber 13.

[0037] In this embodiment, a sharp scraping end 15 is integrally connected to one end of the scraping tongue plate 14 away from the attachment collection box 4. The sharp scraping end 15 is used to scrape off the dust particles attached to the outer wall of the rolling wheel 3. After the dust particles are scraped off, they enter the collection chamber 13 through the scraping tongue plate 14.

[0038] In this embodiment, the back of the sharp scraping end 15 and the scraping tongue 14 are in frictional contact with the outer wall of the rolling wheel 3.

[0039] In this embodiment, side baffles 16 are integrally connected between both ends of the scraping tongue plate 14 and the outer wall of the attachment collection box 4, and the two side baffles 16 are integrally connected to both ends of the sharp scraping end 15.

[0040] The length of the sharp scraping end 15 should be the same as, or at least not less than, the length of the roller. This ensures that dust particles can be scraped from all areas of the roller surface.

[0041] The size of the collection chamber 13 determines the number of dust particles that can be collected. A larger collection chamber 13 can avoid frequent dust particle handling, which would affect construction efficiency. Therefore, one example is to use the horizontal plane tangent to the roller above the roller as the upper tangent plane. The scraping tongue 14 is placed as close as possible to the upper tangent plane, but not beyond it, leaving a larger space between the upper tangent plane and the support frame plate 8 as the space for the collection chamber 13. The bottom surface of the attachment collection box is adapted to the shape of the roller and leaves a certain gap with the roller. This allows for better and more complete utilization of the installation space 9, resulting in a larger collection chamber 13.

[0042] In this embodiment, a support frame plate 8 is bolted to the inner wall of the U-shaped extension beam 6 away from the rolling wheel 2, and an installation space 9 is formed between the top of the support frame plate 8 and the rolling wheel 3 for installing the attachment collection box 4.

[0043] In this embodiment, the attachment collection box 4 fits into the installation space 9, and both sides of the U-shaped extension beam 6 are fixedly connected to the attachment collection box 4 by locking pins 7, so that the attachment collection box 4 is fixed in the installation space 9.

[0044] In this embodiment, a handle 10 is bolted to the top surface of the attachment collection box 4. The handle 10 is designed to facilitate the installation and removal of the attachment collection box 4 by hand.

[0045] In this embodiment, the outer walls of both sides of the attachment collection box 4 are provided with pin holes 12 for connecting the locking pin 7. The locking pin 7 can be a bolt, and the pin hole can be a screw hole, meaning the attachment collection box 4 is fixed to the U-shaped extension beam by bolts. However, screw installation and removal are relatively slow and inconvenient. Therefore, another example is that the locking pin can be a quick-release spring pin as disclosed in patent CN112727884A. This spring pin has a through hole perpendicular to the pin body axis at the head end, with a pull ring fitted in the through hole. The tail end of the pin has a pre-reserved cavity, and the tail end also has a clearance hole communicating with the cavity. An elastic spring piece is provided inside the cavity, located at the top of the cavity. One end of the spring piece is fixed to the side of the cavity away from the clearance hole, and the other end of the spring piece has a hemispherical protrusion that passes through the clearance hole and is located outside the cavity. This structure improves the convenience of inserting or removing the pin. In this patent, the attachment collection box 4 can be fixed to the U-shaped extension beam by simply inserting the pin hole.

[0046] In this device, except for the sharp scraping end 15, all other components can be made of lightweight, low-cost materials such as plastic or aluminum plates; however, the sharp scraping end should be made of wear-resistant metal materials (such as steel or manganese steel). Of course, the scraping tongue and side baffles should also be made of wear-resistant metal materials as much as possible.

[0047] This hydraulic engineering dam filling and compaction auxiliary device, when the compaction vehicle 2 begins to compact the dam body 1, the U-shaped extension beam 6 drives the compaction wheel 3 to roll forward. During the compaction process, due to soil particles, dust, and other factors, a large amount of dust particles gradually adhere to the outer wall of the compaction wheel 3, affecting the subsequent compaction effect. As the compaction wheel 3 continues to rotate, the impurity collection and cleaning component 5 located on the side above the side facing away from the compaction vehicle 2 begins to function. Specifically, the sharp scraping end 15 is in close contact with the outer wall of the compaction wheel 3, using its sharp edge to scrape off the dust particles adhering to the surface of the compaction wheel 3; the scraped dust particles then fall onto the scraping tongue 14 below and slide into the attachment collection box 4 through the tongue.

[0048] The curved slope 11 is located at the bottom of the attachment collection box 4 near the end of the roller. Its function is to further guide the scraped dust particles to fall smoothly into the collection box. At the same time, the tilt angle design of the scraping tongue 14 can effectively prevent dust particles from flying or falling into the external environment. The side baffles 16 are set on both sides of the scraping tongue to prevent dust particles from leaking from both sides.

[0049] All scraped dust particles eventually fall into the collection chamber 13 inside the attachment collection box 4 for centralized storage. The collection chamber has a certain volume to hold a certain amount of dust particles, avoiding frequent cleaning that affects construction efficiency. The attachment collection box 4 is fixed in the installation space 9 formed by the top of the U-shaped extension beam 6 by the support frame plate 8. The attachment collection box 4 can be quickly installed and removed by the locking pin 7 cooperating with the pin hole 12. When the amount of dust particles in the collection chamber reaches a certain amount, the operator can easily remove the attachment collection box 4 through the handle 10 to empty it or replace it with a new collection box.

[0050] After cleaning, the residue collection box 4 can be reinstalled in its original position for continued use.
