Description

Technical Field

[0001] This invention relates to the field of construction machinery technology, and in particular to an intelligent road compaction device for large-area concrete pavement construction. Background Technology

[0002] Concrete is a general term for engineering composite materials made by binding aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in construction processes and always requires pouring. Because concrete is a solid-liquid mixture, unevenness can easily occur during pouring. Therefore, compaction equipment is generally needed to compact the concrete, ensuring a uniform and smooth pour. Only by fully compacting the concrete pavement can its strength, stiffness, stability, and smoothness be guaranteed, thereby extending its service life.

[0003] CN214091045U discloses a portable concrete compaction device, including a base plate and a top plate. A rotating wheel is fixedly installed at the bottom of the base plate, and a fixed bracket is fixedly connected to the top of the base plate. A rainproof baffle is fixed to the top of the fixed bracket, and a support rod is fixedly installed to the top of the base plate, with a handle fixedly connected to its side. The patent describes a device where a slider moves within a groove on the top of the base plate, moving the entire concrete compaction device outside the rainproof baffle. The rainproof baffle on top of the device helps prevent rainwater from damaging it when not in use. Then, an electric pusher descends, causing the top plate to descend, which in turn causes the support column to descend, allowing the fixed block to compact the concrete. The electric pusher ensures that the fixed block can compact the concrete at a uniform and stable speed. However, it relies on manual pushing for movement. When compacting large areas of concrete pavement, the weight of the compaction device necessitates significant manpower. Summary of the Invention

[0004] To address the shortcomings of the existing technologies, an intelligent road compaction device for large-area concrete road construction is provided. When compacting large-area concrete roads, no manual pushing is required, which greatly reduces the physical exertion of construction workers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is an intelligent road compaction device for large-area concrete pavement construction, including a first compaction block and a second compaction block. A rotating plate is respectively provided on both sides of the first compaction block and the second compaction block. A first driving mechanism and a second driving mechanism connected to the rotating plate are respectively provided inside the first compaction block and the second compaction block for driving the second compaction block and the first compaction block to move forward alternately for compaction. The device also includes a controller connected to the first driving mechanism and the second driving mechanism by signal. The controller sends a signal to the first driving mechanism to drive the second compaction block to move forward for compaction. After the second compaction block has moved forward for compaction, the controller sends a stop signal to the first driving mechanism and a start signal to the second driving mechanism to drive the first compaction block to move forward for compaction.

[0006] The aforementioned intelligent road compaction device for large-area concrete road construction includes a first drive mechanism comprising a first drive shaft located inside a first compaction block and fixedly connected to a rotating plate at both ends. First fixed cavities are provided on both sides of the first compaction block. A first bearing with an inner ring connected to the first drive shaft is provided in each fixed cavity. A first positioning bearing is provided inside the first compaction block. A first drive gear is provided on the inner ring of the first positioning bearing. A first drive plate is provided on the inner wall of the first drive gear. A first driven plate is provided on the first drive shaft. A first drive motor is provided below the first drive gear. A first driving gear for meshing with the first drive gear is provided on the first drive motor. The first drive motor is signal-connected to a controller.

[0007] The aforementioned intelligent road compaction device for large-area concrete road construction includes a second drive mechanism comprising a second drive shaft located inside the second compaction block and fixedly connected to a rotating plate at both ends. Second fixed cavities are provided on both sides of the second compaction block. A second bearing with an inner ring connected to the second drive shaft is provided in each of the second fixed cavities. A second positioning bearing is provided inside the second compaction block. A second drive gear is provided on the inner ring of the second positioning bearing. A second drive plate is provided on the inner wall of the second drive gear. A second driven plate is provided on the second drive shaft. A second drive motor is provided below the second drive gear. A second driving gear for meshing with the second drive gear is provided on the second drive motor. The second drive motor is signal-connected to the controller.

[0008] The aforementioned intelligent road compaction device for large-area concrete road construction has a first elastic scraping mechanism on the top surface of the first compaction block that scrapes off the adhesive material on the bottom surface of the second compaction block when the second compaction block moves forward, and a second elastic scraping mechanism on the top surface of the second compaction block that scrapes off the adhesive material on the bottom surface of the first compaction block when the first compaction block moves forward.

[0009] The aforementioned intelligent road compaction device for large-area concrete road construction includes a first elastic scraping mechanism comprising a first fixed plate correspondingly disposed on the top surface of the first compaction block, and a first fixed bearing disposed on the first fixed plate. A first rotating rod is disposed on the inner ring of the first fixed bearing, and a first scraper connecting the two first rotating rods is disposed between the two first rotating rods. A first spring connecting the two is disposed between the first scraper and the top surface of the first compaction block.

[0010] The above-mentioned intelligent road compaction device for large-area concrete road construction includes a second elastic scraping mechanism comprising a second fixed plate correspondingly disposed on the top surface of the second compaction block, and a second fixed bearing disposed on the second fixed plate. A second rotating rod is disposed on the inner ring of the second fixed bearing, and a second scraper is disposed between the two second rotating rods to connect the two. A second spring is disposed between the second scraper and the top surface of the second compaction block to connect the two.

[0011] The beneficial effect of the intelligent road compaction device for large-area concrete road construction of the present invention is that by setting a first compaction block, a second compaction block, a rotating plate, and a first drive mechanism and a second drive mechanism connected to the controller signal, the first compaction block and the second compaction block have both compaction function and self-propelled function. When compacting large-area concrete roads, no manual pushing is required, which greatly reduces the physical exertion of construction personnel.

[0012] The structural design of the first and second drive mechanisms allows the first and second compaction blocks to have both compaction and self-propelled functions. During compaction, the first and second compaction blocks are in a rapid, automatic falling state, which improves the compaction effect. Furthermore, when the first and second compaction blocks are self-propelled, if the first compaction block is above the second compaction block, or vice versa, the two compaction blocks have a compaction effect, meaning that during self-propelled movement, the two compaction blocks also have a compaction effect on the ground.

[0013] Because concrete easily adheres to the bottom surfaces of the first and second compacted blocks during operation, if not cleaned in time, the concrete will solidify on the bottom surfaces of the first and second compacted blocks, resulting in unevenness. By setting up the first and second elastic scraping mechanisms, the concrete that easily adheres to the bottom surfaces of the first and second compacted blocks during operation can be scraped off in real time, improving the flatness of the compaction.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1-4 As shown, an intelligent road compaction device for large-area concrete pavement construction includes a first compaction block 1 and a second compaction block 2. A rotating plate 3 is respectively provided on both sides of the first compaction block 1 and the second compaction block 2. A first drive mechanism and a second drive mechanism, connected to the rotating plate 3, are respectively provided inside the first compaction block 1 and the second compaction block 2 to drive the second compaction block 2 and the first compaction block 1 to move forward alternately for compaction. The device also includes a controller, which is a PLC, connected to the first drive mechanism and signal-connected to the second drive mechanism. The controller sends signals to the first drive mechanism to drive the second compaction block 2 to move forward for compaction. After the second compaction block 2 has moved forward for compaction, the controller sends a stop signal to the first drive mechanism and a start signal to the second drive mechanism to drive the first compaction block 1 to move forward for compaction.

[0023] The first driving mechanism includes a first driving shaft 4 located inside the first compaction block 1 and fixedly connected to the rotating plate 3 at both ends. First fixed cavities are respectively provided on both sides of the first compaction block 1. A first bearing 5 with an inner ring connected to the first driving shaft 4 is provided in the first fixed cavity. A first positioning bearing 6 is provided inside the first compaction block 1. A first driving gear 7 is provided on the inner ring of the first positioning bearing 6. A first driving plate 8 is provided on the inner wall of the first driving gear 7. A first driven plate 9 is provided on the first driving shaft 4. A first driving motor 10 is provided below the first driving gear 7. A first driving gear 11 for meshing with the first driving gear 7 is provided on the first driving motor 10. The first driving motor 10 is signal-connected to the controller.

[0024] The second drive mechanism includes a second drive shaft located inside the second compaction block and fixedly connected to a rotating plate at both ends. Second fixed cavities are respectively provided on both sides of the second compaction block. A second bearing with an inner ring connected to the second drive shaft is provided in each of the second fixed cavities. A second positioning bearing is provided inside the second compaction block. A second drive gear is provided on the inner ring of the second positioning bearing. A second drive plate is provided on the inner wall of the second drive gear. A second driven plate is provided on the second drive shaft. A second drive motor is provided below the second drive gear. A second driving gear for meshing with the second drive gear is provided on the second drive motor. The second drive motor is signal-connected to a controller. The second drive mechanism has the same structure as the first drive mechanism and is therefore not shown in the figure.

[0025] By setting up a first compaction block, a second compaction block, a rotating plate, and a first drive mechanism and a second drive mechanism connected to the controller signal, the first and second compaction blocks have both compaction and self-propelled functions. When compacting large areas of concrete pavement, no manual pushing is required, which greatly reduces the physical exertion of construction workers.

[0026] The structural design of the first and second drive mechanisms allows the first and second compaction blocks to have both compaction and self-propelled functions. During compaction, the first and second compaction blocks are in a rapid, automatic falling state, which improves the compaction effect. Furthermore, when the first and second compaction blocks are self-propelled, if the first compaction block is above the second compaction block, or vice versa, the two compaction blocks have a compaction effect, meaning that during self-propelled movement, the two compaction blocks also have a compaction effect on the ground.

[0027] Example 2

[0028] The parts that are the same as in Example 1 will not be repeated here. The difference is that: Figure 5-6 As shown, a first elastic scraping mechanism is provided on the top surface of the first compaction block 1 to scrape off the adhesive on the bottom surface of the second compaction block 2 when the second compaction block 2 moves forward, and a second elastic scraping mechanism is provided on the top surface of the second compaction block 2 to scrape off the adhesive on the bottom surface of the first compaction block 1 when the first compaction block 1 moves forward.

[0029] The first elastic scraping mechanism includes a first fixed plate 12 correspondingly disposed on the top surface of the first compaction block 1, and a first fixed bearing disposed on the first fixed plate 12. A first rotating rod 13 is disposed on the inner ring of the first fixed bearing. A first scraper 14 connecting the two first rotating rods 13 is disposed between the two first rotating rods 13. A first spring 15 for connecting the two is disposed between the first scraper 14 and the top surface of the first compaction block 1.

[0030] The second elastic scraping mechanism includes a second fixed plate correspondingly disposed on the top surface of the second compacted block, and a second fixed bearing disposed on the second fixed plate. A second rotating rod is disposed on the inner ring of the second fixed bearing, and a second scraper connecting the two second rotating rods is disposed between the two second rotating rods. A second spring connecting the two is disposed between the second scraper and the top surface of the second compacted block. The first elastic scraping mechanism and the second elastic scraping mechanism have the same structure, so they are not shown in the figure.

[0031] Because concrete easily adheres to the bottom surfaces of the first and second compacted blocks during operation, if not cleaned promptly, the concrete will solidify on these surfaces, resulting in unevenness. By incorporating a first and a second elastic scraping mechanism, concrete adhering to the bottom surfaces of the first and second compacted blocks can be scraped away in real time, improving the flatness of the compaction. The first spring ensures that the first scraper is in constant contact with the bottom surface of the second compacted block, and their opposing directions of movement allow for the removal of adhering material from the bottom surface of the second compacted block. Furthermore, after the first scraper detaches from the bottom surface of the second compacted block, it can swing back and forth under the elastic action of the first spring, further reducing the adhesion of adhering material to the first scraper. The second spring, which causes the second scraper to remove adhering material from the bottom surface of the first compacted block and reduce its adhesion to the second scraper, operates on the same principle as the first spring and will not be elaborated further here.

[0032] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
