Description

Technical Field

[0001] This utility model relates to the technical field of foundation leveling equipment, specifically to a foundation leveling equipment for building engineering. Background Technology

[0002] Foundation refers to the soil or rock mass supporting a building. Soil layers used as building foundations are classified as rock, gravelly soil, sandy soil, silty soil, clayey soil, and artificial fill. Foundations are divided into natural foundations and artificial foundations. Natural foundations are natural soil layers that do not require reinforcement, while artificial foundations require reinforcement treatment, commonly including stone chip cushion layers, sand cushion layers, and mixed lime-soil backfill followed by compaction. Therefore, foundation leveling equipment is frequently used on construction sites. Foundation leveling equipment for building engineering is an indispensable tool in construction. It is mainly used to adjust the soil surface to meet the design requirements for flatness and density, so that it can be used for subsequent construction or crop growth. This foundation leveling equipment is widely used in road construction, urban construction, agricultural production, and other fields. The following problems exist with existing technologies:

[0003] Existing foundation leveling equipment for construction projects lacks a loosening tooth adjustment component. When facing foundations of varying hardness, the loosening effect of the equipment is significantly reduced. Because the loosening teeth in the existing device can only be inserted into the soil at a fixed angle and depth, it cannot effectively cope with different foundation hardnesses, nor can it be flexibly adjusted according to specific soil conditions and construction requirements, thus reducing the equipment's versatility. In addition, the existing device lacks a scraper height and angle adjustment component, making it difficult to effectively handle complex situations such as protrusions, depressions, and slopes on the foundation surface. Furthermore, the lack of precise angle may cause soil to accumulate in inappropriate places, or local unevenness may require repeated work, further reducing the equipment's leveling efficiency.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 , Figure 2 As shown, this utility model provides a foundation leveling device for construction engineering, including a grader body 10. First wheel mechanisms 12 are provided on both the left and right sides of the grader body 10. An L-shaped frame 11 is fixedly connected to the front side of the grader body 10. Two left-right symmetrical second wheel mechanisms 14 are provided at the end of the L-shaped frame 11 away from the grader body 10. A soil loosening tooth adjustment component 2 and a scraper height and angle adjustment component 3 are provided on the inner wall of the front side of the L-shaped frame 11. A second scraper angle adjustment component 4 is provided at the bottom of the scraper height and angle adjustment component 3. A leveling scraper 13 is provided on the front side of the second scraper angle adjustment component 4.

[0023] The equipment mainly relies on the first wheel mechanism 12 on both sides of the grader body 10 and the two left-right symmetrical second wheel mechanisms 14 at the front end of the L-shaped frame 11 to move. The first wheel mechanism 12 and the second wheel mechanism 14 together support the entire equipment, enabling the equipment to move smoothly on the foundation of the construction project for subsequent leveling operations. The loosening tooth adjustment component 2 is mainly used to adjust the position of the loosening tooth to adapt to different foundation loosening needs. The scraper height and angle adjustment component 3 can flexibly adjust the height and angle of the scraper. It should be noted that the grader body 10, the first wheel mechanism 12, and the second wheel mechanism 14 are all existing technologies and will not be described in detail here.

[0024] like Figure 3As shown, the soil loosening tooth adjustment assembly 2 includes a cylinder 20. The top of the cylinder 20 is rotatably connected to the front side of the inner top wall of the L-shaped frame 11. Fixing plates 26 are fixedly connected to the front of both the left and right side walls of the L-shaped frame 11. L-shaped fixing rods 25 are rotatably connected to the upper side of the opposite sides of the two fixing plates 26. Soil loosening teeth 27 are fixedly connected to the ends of the two L-shaped fixing rods 25 away from the fixing plates 26. Two symmetrical side plates 21 are fixedly connected to the front side of the inner top wall of the L-shaped frame 11. Rotating rods 22 are rotatably connected to the opposite sides of the two side plates 21. The left and right ends of the rotating rods 22 pass through to the opposite sides of the two side plates 21 and are fixedly connected to L-shaped connecting rods 23. The ends of the two L-shaped connecting rods 23 away from the rotating rods 22 are rotatably connected to the bends of the two L-shaped fixing rods 25. An adjustment block 24 is fixedly connected to the middle of the outer wall of the rotating rod 22. The output end of the cylinder 20 is rotatably connected to the adjustment block 24.

[0025] When the position of the loosening tooth 27 needs to be adjusted, cylinder 20 is activated. The output end of cylinder 20 extends and retracts. Since cylinder 20 is rotatably connected to the adjusting block 24, the extension and retraction of cylinder 20 will drive the rotating rod 22 to rotate. When the rotating rod 22 rotates, it drives the L-shaped fixed rod 25 to rotate around its connection point with the fixed plate 26 through the L-shaped connecting rod 23, thereby realizing the adjustment of the up and down position of the loosening tooth 27. When working on a relatively hard foundation, the loosening tooth 27 can be adjusted downward by cylinder 20 so that it can be inserted deeper into the soil for loosening operations. Through the set loosening tooth adjustment component 2, the position of the loosening tooth 27 can be flexibly adjusted according to the actual hardness of the foundation, so that its insertion depth into the soil is more reasonable, improving the loosening effect, thereby more effectively breaking and loosening hard soil layers, preparing for subsequent leveling operations, and also better adapting to various different site conditions, greatly improving the versatility of the equipment.

[0026] like Figure 4 , Figure 5 As shown, the scraper height and angle adjustment assembly 3 includes a rotating horizontal plate 30. The front end of the rotating horizontal plate 30 is rotatably connected to the middle of the front inner wall of the L-shaped frame 11. A triangular plate 31 is fixedly connected to the rear side of the rotating horizontal plate 30. A cylinder 32 is provided on the top of the triangular plate 31 and is rotatably connected to the inner top wall of the L-shaped frame 11. The output end of the cylinder 32 is rotatably connected to the rear top of the triangular plate 31.

[0027] like Figure 4 , Figure 5As shown, a motor 33 is fixedly connected to the top front side of the triangle plate 31. The output end of the motor 33 extends through to the bottom of the triangle plate 31 and is fixedly connected to a main gear 34. A driven gear 35 is meshed with the rear side of the main gear 34. The top of the driven gear 35 is rotatably connected to the bottom of the triangle plate 31. An arc-shaped fixing frame 36 is fixedly connected to the bottom of the driven gear 35.

[0028] When the height of the scraper needs to be adjusted, cylinder 2 32 is activated. The output end of cylinder 2 32 extends and retracts, pushing the triangular plate 31 to rotate around the connection point between the rotating horizontal plate 30 and the inner top wall of the L-shaped frame 11. This causes the entire scraper height and angle adjustment assembly 3 to move up and down, thereby adjusting the height of the leveling scraper 13. For example, when there are large protrusions or depressions on the foundation surface, the height of the leveling scraper 13 can be adjusted to better fit the foundation surface for leveling operations. When the angle of the scraper needs to be adjusted, motor 1 33 is activated. Motor 1 33 drives the main gear 34 to rotate. The main gear 34 drives the driven gear 35 to rotate through meshing, thereby causing the arc-shaped fixed frame 36 to rotate around its connection point with the triangular plate 31, achieving the initial adjustment of the scraper angle.

[0029] like Figure 6 As shown, the second scraper angle adjustment assembly 4 includes a hollow fixed column 40. The left and right ends of the hollow fixed column 40 are fixedly connected to the bottom of the arc-shaped fixed frame 36. A first fixed rod 41 is rotatably connected inside the hollow fixed column 40. A connecting plate 47, which is fixedly connected to the rear side wall of the leveling scraper 13, is fixedly connected to both sides of the first fixed rod 41. A second fixed rod 42 is fixedly connected to the top of the opposite side of the connecting plate 47. A second motor 45 is fixedly connected to the bottom of the inner walls of both sides of the arc-shaped fixed frame 36. The output ends of the two second motors 45 pass through to the outer walls of the left and right sides of the arc-shaped fixed frame 36 and are fixedly connected to rotating blocks 46. A fixed column 44 is rotatably connected above the two rotating blocks 46. An adjusting rod 43 is fixedly connected to the end of the two fixed columns 44 that is close to each other. The ends of the two adjusting rods 43 that are away from the fixed column 44 are rotatably connected to the left and right sides of the outer wall of the second fixed rod 42.

[0030] When further precise adjustment of the leveling scraper 13 angle is required, the two motors 45 are activated. Motors 45 drive the rotating block 46 to rotate. As the rotating block 46 rotates, the linkage between the fixed column 44 and the adjusting rod 43 pushes the fixed rod 42 to rotate around the fixed rod 41, thereby causing the connecting plate 47 and the leveling scraper 13 connected to the connecting plate 47 to make fine adjustments to the angle, achieving a more ideal foundation leveling effect. When leveling some corner areas or areas requiring higher flatness, fine adjustments are made through the second scraper angle adjustment component 4. The function allows the leveling scraper 13 to better conform to the foundation surface for operation. Through the set scraper height and angle adjustment component 3 and the second scraper angle adjustment component 4, the height and angle of the scraper can be finely adjusted, thereby achieving precise control of the foundation leveling effect. This avoids uneven accumulation or undesirable flow of soil during the leveling process, making the leveled foundation surface flatter and smoother, meeting the strict requirements of building engineering for foundation flatness. At the same time, it reduces the number of repeated operations required due to local unevenness, improving construction quality and efficiency.

[0031] The working principle of the foundation leveling equipment used in this construction project will be explained in detail below.

[0032] like Figure 1-6 As shown, when the position of the loosening tooth 27 needs to be adjusted, cylinder 20 is activated, and the output end of cylinder 20 extends and retracts. Since cylinder 20 is rotatably connected to the adjusting block 24, the extension and retraction of cylinder 20 will drive the rotating rod 22 to rotate. When the rotating rod 22 rotates, it drives the L-shaped fixed rod 25 to rotate around its connection point with the fixed plate 26 through the L-shaped connecting rod 23, thereby realizing the adjustment of the up and down position of the loosening tooth 27. When working on a relatively hard foundation, the loosening tooth 27 can be adjusted downward by cylinder 20 so that it can be inserted deeper into the soil for loosening operations. Through the set loosening tooth adjustment component 2, the position of the loosening tooth 27 can be flexibly adjusted according to the actual hardness of the foundation, so that the depth of insertion into the soil is more reasonable, improving the loosening effect, thereby more effectively breaking and loosening the hard soil layer, preparing for subsequent leveling operations, and also better adapting to various different site conditions, greatly improving the versatility of the equipment.

[0033] When the height of the scraper needs to be adjusted, cylinder 2 32 is activated. The output end of cylinder 2 32 extends and retracts, pushing the triangular plate 31 to rotate around the connection point between the rotating horizontal plate 30 and the inner top wall of the L-shaped frame 11. This causes the entire scraper height and angle adjustment assembly 3 to move up and down, thereby adjusting the height of the leveling scraper 13. For example, when there are large protrusions or depressions on the foundation surface, the height of the leveling scraper 13 can be adjusted to better fit the foundation surface for leveling operations. When the angle of the scraper needs to be adjusted, motor 1 33 is activated. Motor 1 33 drives the main gear 34 to rotate. The main gear 34 drives the driven gear 35 to rotate through meshing, thereby causing the arc-shaped fixed frame 36 to rotate around its connection point with the triangular plate 31, achieving the initial adjustment of the scraper angle.

[0034] When further precise adjustment of the leveling scraper 13 angle is required, the two motors 45 are activated. Motors 45 drive the rotating block 46 to rotate. As the rotating block 46 rotates, the linkage between the fixed column 44 and the adjusting rod 43 pushes the fixed rod 42 to rotate around the fixed rod 41, thereby causing the connecting plate 47 and the leveling scraper 13 connected to the connecting plate 47 to make fine adjustments to the angle, achieving a more ideal foundation leveling effect. When leveling some corner areas or areas requiring higher flatness, fine adjustments are made through the second scraper angle adjustment component 4. The function allows the leveling scraper 13 to better conform to the foundation surface for operation. Through the set scraper height and angle adjustment component 3 and the second scraper angle adjustment component 4, the height and angle of the scraper can be finely adjusted, thereby achieving precise control of the foundation leveling effect. This avoids uneven accumulation or undesirable flow of soil during the leveling process, making the leveled foundation surface flatter and smoother, meeting the strict requirements of building engineering for foundation flatness. At the same time, it reduces the number of repeated operations required due to local unevenness, improving construction quality and efficiency.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
