Description

Technical Field

[0001] This utility model belongs to the field of pumped storage power station construction technology, and in particular, it is a compaction device for the construction of asphalt concrete panels in pumped storage power stations. Background Technology

[0002] In modern infrastructure construction, road rollers, as a commonly used engineering machinery, are widely used in the compaction of asphalt concrete or soil layers in roads, bridges, airport runways, and water conservancy projects. With the continuous development of pumped storage power station projects, higher requirements are being placed on construction quality and efficiency. Especially during the construction of asphalt concrete panels, surface cleanliness directly affects the subsequent compaction effect and the stability and durability of the overall structure. Therefore, a device capable of efficiently removing dust particles and solid impurities from the construction surface and immediately performing high-quality compaction after cleaning is particularly important. This invention proposes a "compacting device for asphalt concrete panel construction in pumped storage power stations," designed precisely based on this need.

[0003] Currently, the following problems are common in the construction of asphalt concrete panels for pumped storage power stations: On the one hand, traditional road rollers focus on compaction and lack effective pre-cleaning structures, resulting in dust, gravel, and other impurities being compacted and embedded in the concrete before being removed in time, causing quality problems such as hollowing, cracking, and even leakage; on the other hand, some construction sites rely on manual cleaning or additional single cleaning equipment, which is not only inefficient but also makes it difficult to ensure continuity and consistency, affecting the overall construction progress and quality control. Utility Model Content

[0004] The purpose of this invention is to provide a compaction device for the construction of asphalt concrete panels in pumped storage power stations, 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 device for asphalt concrete panel construction in a pumped storage power station, comprising a roller body, an installation frame at the forward end of the roller body, a compaction roller rotatably mounted in the installation frame, connecting rods fixed to the outer walls on both sides of the forward end of the installation frame, an extension plate welded between the ends of the two connecting rods away from the installation frame, the extension plate being located in front of the compaction roller, a front cleaning component provided on the bottom surface of the extension plate, the front cleaning component including cleaning parts symmetrically arranged on the bottom surface of the extension plate for cleaning dust particles one in front and one behind, and a solid impurity removal part for removing protruding particles and stones on the asphalt concrete panel of the pumped storage power station being provided in the middle of the cleaning parts and on the bottom surface of the extension plate.

[0006] In a preferred embodiment, two first body supports are symmetrically welded to the bottom surface of the extension frame plate, and a second body support is welded between the two first body supports and located on the bottom surface of the extension frame plate.

[0007] In a preferred embodiment, the two ends of the first strip support are integrally connected with a first side edge dust pusher plate, and the two ends of the second strip support are integrally connected with a second side edge dust pusher plate.

[0008] In this preferred embodiment, the first side edge dust pusher plate and the second side edge dust pusher plate on the same side are arranged in parallel, and the included angle between the first side edge dust pusher plate and the first strip support is 90°-180°, and the included angle between the second side edge dust pusher plate and the second strip support is also 90°-180°.

[0009] In a preferred embodiment, the cleaning component includes a first cleaning brush fixed to the bottom surface of the first side edge dust pusher plate on the front side and a second cleaning brush fixed to the bottom surface of the first side edge dust pusher plate on the rear side.

[0010] In a preferred embodiment of this solution, the solid impurity removal component includes a cleaning scraper fixed to the bottom surface of the second body support and the second side edge dust pusher, wherein the bottom end of the cleaning scraper is integrally formed with a sharp scraping tip.

[0011] In this preferred embodiment, the first cleaning brush, the second cleaning brush, and the sharp scraping tip all make frictional contact with the surface of the asphalt concrete panel of the pumped storage power station.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] The compaction device used for asphalt concrete panel construction in this pumped storage power station features a pre-cleaning component added in front of the compaction roller. This component includes a symmetrically arranged front and rear cleaning part and a solid impurity removal part in the middle. This enables a step-by-step and phased efficient cleaning process. The first cleaning brush on the front side sweeps away loose dust, while the cleaning scraper and sharp scraper in the middle powerfully remove adhering particles and stones. The second cleaning brush on the rear side sweeps away residual dust again, effectively removing impurities of various shapes and significantly improving the cleanliness of the base surface, thus providing a good foundation for subsequent compaction.

[0014] The pre-cleaning structure design ensures that impurities are removed before compaction. The sharp scraping tip of the cleaning scraper can remove highly adhesive or protruding particles. As the scraper moves forward with the vehicle, it directly contacts the asphalt concrete surface to thoroughly remove impurities. The brush further assists in removing fine particles to prevent omissions and avoids impurities from embedding in the compacted layer, reducing construction defects and improving the overall strength and durability of the asphalt panel.

[0015] The cleaning design adopts a "three-stage cleaning + compaction" approach. The first round of cleaning is for initial dust removal and solid removal, which powerfully scrapes off attached particles. The second round of cleaning is for fine treatment of residues. Finally, compaction is achieved by completing high-quality compaction in a state free of impurities. This is significantly better than the traditional single-sweep method or the method of simply crushing with compaction rollers, resulting in higher surface cleanliness and better compaction uniformity.

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] This embodiment provides, for example Figures 1 to 4 The compaction device shown is used for the construction of asphalt concrete panels for pumped storage power stations. It includes a roller body 1, an installation frame 2 at the forward end of the roller body 1, a compaction roller 3 rotatably installed in the installation frame 2, connecting rods 5 fixed on both outer walls of the forward end of the installation frame 2, an extension plate 4 welded between the ends of the two connecting rods 5 away from the installation frame 2, the extension plate 4 being located in front of the compaction roller 3, and a front cleaning component 6 provided on the bottom surface of the extension plate 4. The front cleaning component 6 includes cleaning parts symmetrically arranged on the bottom surface of the extension plate 4 for cleaning dust particles one in front and one behind, and a solid impurity removal part for removing protruding particles and stones on the asphalt concrete panels of the pumped storage power station located in the middle of the cleaning parts and on the bottom surface of the extension plate 4. The design of the front and rear cleaning components allows for the first push-and-sweep cleaning of dust particles on the surface of the asphalt concrete panel. Then, the solid impurity removal component removes solid impurities, including protruding particles and stones, that were not removed from the surface of the asphalt concrete panel in the first round of cleaning. Finally, the second round of cleaning removes the dust remaining after removing the protruding particles. After the pre-cleaning is completed, the compaction roller 3 begins to compact the asphalt concrete panel, thereby improving the cleaning effect and preventing impurities from adhering to the surface of the asphalt concrete panel.

[0026] In this embodiment, two first body supports 11 are symmetrically welded to the bottom surface of the extension frame plate 4, and a second body support 12 is welded between the two first body supports 11 and located on the bottom surface of the extension frame plate 4.

[0027] In this embodiment, the two ends of the two first body supports 11 are integrally connected to the first side edge dust pusher plates 10, and the two ends of the second body supports 12 are integrally connected to the second side edge dust pusher plates 13. The design of the first side edge dust pusher plates 10 and the second side edge dust pusher plates 13 can push dust particles or solid impurities during the cleaning process to both sides, preventing dust particles or solid impurities from escaping and being compacted and embedded into the asphalt concrete panel by the compaction roller 3.

[0028] In this embodiment, the first side edge dust pusher plate 10 and the second side edge dust pusher plate 13 on the same side are arranged in parallel, and the included angle between the first side edge dust pusher plate 10 and the first strip support 11 is 90°-180°, and the included angle between the second side edge dust pusher plate 13 and the second strip support 12 is also 90°-180°.

[0029] In this embodiment, the cleaning component includes a first cleaning brush 7 fixed to the bottom surface of the first strip support 11 and the first side edge dust pusher 10 on the front side, and a second cleaning brush 9 fixed to the bottom surface of the first strip support 11 and the first side edge dust pusher 10 on the rear side.

[0030] In this embodiment, the solid impurity removal component includes a cleaning scraper 8 fixed to the bottom surface of the second strip support 12 and the second side edge dust pusher 13. The bottom end of the cleaning scraper 8 is integrally formed with a sharp scraping end 14.

[0031] In this embodiment, the first cleaning brush 7, the second cleaning brush 9, and the sharp scraping end 14 all come into frictional contact with the surface of the asphalt concrete panel of the pumped storage power station.

[0032] Working principle

[0033] The compaction device used for the construction of asphalt concrete panels in this pumped storage power station involves the roller vehicle 1 moving forward after starting and entering the area of ​​the asphalt concrete panel to be compacted. The mounting frame 2 is fixed to the front end of the vehicle, which drives the entire front cleaning assembly to move forward synchronously with the vehicle.

[0034] The front cleaning component starts working, and the first round of cleaning (front side cleaning) begins: the first cleaning brush 7 is located at the bottom of the first front support 11 and the first side edge dust pusher 10. As the vehicle moves forward, it contacts the ground and performs a preliminary cleaning of the asphalt concrete panel surface, mainly removing loose dust particles to prepare for subsequent treatment. After the first round of cleaning, the cleaning scraper 8 and its sharp scraping end 14 begin to work. The scraper uses its sharp end to forcefully scrape off larger impurities such as protruding particles and gravel attached to the asphalt concrete panel. The scraped impurities are concentrated in the middle area or on both sides.

[0035] Second round of cleaning (rear side cleaning): The second cleaning brush 9 is located at the bottom of the first strip support 11 and the first side edge dust pusher 10 on the rear side, and performs a second cleaning of the residual dust left after scraping to ensure that the surface is clean and free of impurities.

[0036] The first side edge dust pusher 10 and the second side edge dust pusher 13 are respectively fixed to the two ends of the first body support 11 and the second body support 12. As the vehicle moves forward, the dust pusher pushes the dust and particles generated during the sweeping process to the left and right sides to prevent these impurities from being stuck in the middle area. The angle of the dust pusher is designed to be between 90° and 180° to ensure that impurities will not flow back or leak through the net.

[0037] After the pre-cleaning components have completed all sweeping and impurity removal, the compaction roller 3 begins to compact the cleaned asphalt concrete panel. Because the surface has been cleaned, the compaction effect is better, avoiding problems such as uneven road surface or insufficient strength caused by embedded impurities. The roller continues to move forward, repeating the above cleaning and compaction process, gradually covering the entire asphalt concrete panel construction area. The operator can adjust parameters such as vehicle speed, cleaning angle, and scraper pressure according to actual construction needs to adapt to different working conditions.

[0038] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
