Description

Technical Field

[0001] This utility model belongs to the field of leveling technology and relates to a dam paving and leveling machine. Background Technology

[0002] In water conservancy projects, dam concrete construction is a crucial step, as its quality directly affects the structural safety and service life of the dam. During construction, concrete paving and leveling are typically done manually; however, this method presents numerous problems. Workers must walk on the uncured concrete surface to perform the paving work, which is not only inefficient but also prone to slips and falls, causing serious safety issues. Dam paving and leveling machines, as specialized engineering machinery for dam concrete construction, still require manual assistance during actual construction. Existing equipment lacks height adjustment capabilities, potentially leading to quality problems such as waves, segregation, or cracks in the paved layer. To compensate for insufficient height, workers may over-pave concrete, increasing material costs and significantly increasing subsequent finishing work, further raising construction costs. Utility Model Content

[0003] The purpose of this invention is to provide a dam paving and leveling machine, which solves the problem that existing devices cannot adjust the height.

[0004] The technical solution adopted by this utility model is a dam paving and leveling machine, which includes two support components. The bottom inner cavity of each of the two support components is rotatably connected to a moving component. An adjusting component is fixedly connected between the two support components. A leveling component is slidably connected to the bottom of the inner cavity of the adjusting component. A lifting component is fixedly connected to the top of the adjusting component. The lifting component is also connected to two support components.

[0005] The features of this utility model also include:

[0006] The support assembly includes a first fixing frame, which is a hollow structure, and two sliding plates are arranged in the inner cavities of the first fixing frames along the horizontal direction.

[0007] The moving component includes rotating wheels. Two rotating wheels are rotatably connected to the bottom inner cavity of each first fixed frame. The rotating wheels are located at both ends of the first fixed frame. A first pulley is fixedly connected to the corresponding position on the side of the rotating shaft away from the adjustment component of each rotating wheel. A first belt is wound around the outer surface of the two rotating wheels on each first fixed frame. A first motor is set at the corresponding position on one end of the two first belts. The output end of the first motor is fixedly connected to the rotating shaft of the first pulley. A fixed plate is fixedly connected to the top of each of the two first motors.

[0008] The adjustment assembly includes a second fixed frame, with two ends of the second fixed frame fixedly connected to two sliding plates respectively. A threaded rod is rotatably connected to one side of the inner cavity of the second fixed frame along the direction perpendicular to the sliding plates, and a scraper is fixedly connected to the bottom of the second fixed frame near the threaded rod.

[0009] A guide rod is fixedly connected to the inner cavity of the second fixed bracket on the side away from the threaded rod.

[0010] The leveling assembly includes a sliding shell. One side of the sliding shell has a through hole through which a guide rod passes. The other side of the sliding shell has a threaded hole through which a matching threaded rod passes. The sliding shell is slidably connected to the threaded rod and the guide rod.

[0011] A second motor is fixedly connected to the top wall of the inner cavity of the sliding housing. A first bevel gear is fixedly connected to the output end of the second motor via a coupling.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model of a dam paving and leveling machine, through its set moving components, can continuously advance along the dam slope or plane, reducing downtime and accelerating the overall construction progress. At the same time, the uniform vibration during movement prevents concrete stratification or air bubble accumulation, ensuring uniform density. Furthermore, traditional manual leveling requires workers to walk on uncured concrete surfaces, while mechanical operation keeps personnel away from dangerous areas, reducing the risk of falls and slips. In addition, the device can quickly level the surface, which can shorten the construction period and indirectly reduce financial costs.

[0017] 2. This utility model of a dam paving and leveling machine, through the setting of adjustment components, leveling components and lifting components, can adjust the height of the scraper of the leveling machine to ensure that the concrete paving thickness is consistent with the design value, adapt to the thickness requirements of different areas of the dam, and the operator does not need to stop the machine to manually adjust the height, thus improving the continuity of construction. At the same time, the automated height adjustment reduces the risk of operators entering uncompacted areas, and significantly reduces the rate of work-related accidents. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Dam paving and leveling machine, such as Figure 1 As shown, it includes two support components 1.

[0026] like Figure 2 As shown, the support assembly 1 includes a first fixing frame 11, which is a hollow structure, and two sliding plates 12 are arranged in the inner cavities of the first fixing frames 11 along the horizontal direction.

[0027] like Figure 3 As shown, the moving component 2 includes rotating wheels 21. Two rotating wheels 21 are rotatably connected to the bottom inner cavity of each first fixed frame 11. The rotating wheels 21 are located at both ends of the first fixed frame 11. A first pulley 22 is fixedly connected to the corresponding position on the side of the rotating shaft of each rotating wheel 21 away from the adjusting component 3. A first belt 23 is wound around the outer surface of the two rotating wheels 21 on each first fixed frame 11. A first motor 25 is set at the corresponding position on one end of the two first belts 23. The output end of the first motor 25 is fixedly connected to the rotating shaft of the first pulley 22. A fixed plate 24 is fixedly connected to the top of each of the two first motors 25.

[0028] like Figure 2 As shown, the adjusting assembly 3 includes a second fixed frame 31, with both ends of the second fixed frame 31 fixedly connected to two sliding plates 12 respectively. A threaded rod 32 is rotatably connected to one side of the inner cavity of the second fixed frame 31 along the direction perpendicular to the sliding plates 12. A scraper 34 is fixedly connected to the bottom of the second fixed frame 31 near the threaded rod 32. A guide rod 33 is fixedly connected to the inner cavity of the second fixed frame 31 away from the threaded rod 32.

[0029] like Figure 4 As shown, the leveling assembly 4 includes a sliding shell 41. A through hole is formed on one side of the sliding shell 41, through which a guide rod 33 passes. A threaded hole is formed on the other side of the sliding shell 41, through which a mating threaded rod 32 passes. The sliding shell 41 is slidably connected to the threaded rod 32 and the guide rod 33. A second motor 42 is fixedly connected to the top wall of the inner cavity of the sliding shell 41. A first bevel gear 43 is fixedly connected to the output end of the second motor 42 via a coupling. A leveling plate 44 is fixedly connected to the end of the first bevel gear 43 away from the second motor 42. A second bevel gear 45 is meshed with the outer surface of the first bevel gear 43. A second pulley 46 is fixedly connected to the end of the second bevel gear 45 away from the first bevel gear 43. A third pulley 47 is rotatably connected to the inner cavity of the sliding shell 41 away from the second pulley 46. A second belt 48 is wound around the outer surfaces of the second pulley 46 and the third pulley 47. The inner surface of the third pulley 47 meshes with the outer surface of the threaded rod 32.

[0030] like Figure 5As shown, the lifting assembly 5 includes a dual-axis motor 51. The bottom of the dual-axis motor 51 is fixedly connected to the second fixed frame 31. First recovery rollers 52 are fixedly connected to the output ends on both sides of the dual-axis motor 51. Each of the two first recovery rollers 52, at the end furthest from the dual-axis motor 51, is fixedly connected to a second recovery roller 54 via a coupling. First steel wire ropes 53 are wound around the outer surfaces of both first recovery rollers 52, and second steel wire ropes 55 are wound around the outer surfaces of both second recovery rollers 54. The two first steel wire ropes 53 are jointly fixedly connected to one of the sliding plates 12, and the two second steel wire ropes 55 are jointly fixedly connected to the other sliding plate 12.

[0031] The working principle of this dam paving and leveling machine is as follows: The first motor 25 is started, driving the first pulley 22, which is fixedly connected to the output end of the first motor 25, to rotate. Simultaneously, the rotating wheel 21, fixedly connected to the pulley 22, rotates, thereby driving the first belt 23 to rotate. The first belt 23 then drives the other end of the first pulley 22 and the rotating wheel 21 to rotate, thus moving the dam paving and leveling machine to the position on the dam that needs leveling. Subsequently, the second motor 42 is started, driving the first bevel gear 43. The first bevel gear 43 drives the second bevel gear 45 to rotate, thereby driving the second pulley 46 to rotate. The second pulley 46 drives the second belt 48, which in turn drives the third pulley 47 to rotate, thereby driving the leveling plate 44 and the threaded rod 32 to rotate. This causes the sliding shell 41 to move up and down on the dam's slope, moving the leveling plate 44 and leveling the dam. Once the leveling plate 44 has leveled this area of ​​the dam, the first motor 25 is started. As the moving components move, the scraper 34 will also simply scrape the dam flat, moving excess concrete to the next area.

[0032] When the leveling depth needs to be adjusted, the dual-axis motor 51 is started. The dual-axis motor 51 drives the first recovery roller 52 and the second recovery roller 54 to rotate, thereby causing the first recovery roller 52 and the second recovery roller 54 to pull back the first wire rope 53 and the second wire rope 55, which in turn pulls the sliding plate 12 up, thereby driving the first fixed frame 11 to pull the second fixed frame 31 and the leveling plate 44 up, thereby adjusting the leveling depth.

The lifting component 5 is also connected to two support components 1.

[0035] In this embodiment, during implementation, the operator first activates the moving component 2 to move the device to the position where leveling is required. Then, the operator activates the leveling component 4, which rotates and moves up and down simultaneously to level the dam. When the leveling depth needs to be adjusted, the operator activates the lifting component 5 to rotate, which in turn pulls the support component 1 to move up and down. This, in turn, allows the support component 1 to pull the adjusting component 3 and the leveling component 4 to move up and down, thus adjusting the leveling depth.
