[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0027] Please refer to Figures 1 to 7 The above technical solutions will be described in detail by the following embodiments of the present utility model

[0028] A ground leveling device for concrete construction, comprising: a frame 1; a gearbox 2 is arranged inside the frame 1, a gantry 3 is fixedly connected to the top of the gearbox 2, the gantry 3 is slidably connected to the frame 1, and two vibration sleeves 4 are arranged at the bottom of the gearbox 2, and the vibration sleeves 4 are all threadedly connected to the gearbox 2; scraping plates 5 are fixedly connected to both sides of the bottom of the gearbox 2; a vibration mechanism 6 for discharging the air inside the concrete is arranged inside the vibration sleeve 4; a leveling mechanism 7 for controlling the reciprocating movement of the scraping plate 5 is arranged inside the gantry 3. The user can insert the vibration sleeve 4 into the concrete, and then control the gantry 3 to reciprocate horizontally through the leveling mechanism 7. While the gantry 3 moves, it drives the gearbox 2, and the gearbox 2 drives the scraping plate 5 to level the concrete. At the same time, the vibration mechanism 6 inside the vibration sleeve 4 generates high-frequency vibration, thereby improving the fluidity of the concrete. The vibration sleeve 4 can be inserted deep into the concrete while the device levels the concrete, and the fluidity of the concrete is improved by vibration, thereby discharging the air bubbles in the concrete, solving the problem that due to the poor fluidity of the concrete, there are a large number of air bubbles inside it, and the existing ground leveling devices for concrete construction cannot discharge the air bubbles inside the concrete, resulting in a large number of pores inside the concrete after solidification, making the ground strength low.

[0029] As Figure 3 and Figure 4 shown, the vibration mechanism 6 includes: an eccentric shaft 8 is arranged inside the vibration sleeve 4, a first limiting sleeve 9 is rotatably connected to the outer surface of the bottom end of the eccentric shaft 8, a second limiting sleeve 10 is rotatably connected to the outer surface of the top end of the eccentric shaft 8, and both the first limiting sleeve 9 and the second limiting sleeve 10 are fixedly connected to the vibration sleeve 4; a first rotating shaft 11 is fixedly connected to the top end of the eccentric shaft 8, and the top end of the first rotating shaft 11 penetrates through the vibration sleeve 4 and extends into the gearbox 2; speed increasing mechanisms 12 for controlling the high-speed rotation of the eccentric shaft 8 are arranged on the outer surface of the first rotating shaft 11 located inside the gearbox 2. The speed increasing mechanisms 12 control the high-speed rotation of the first rotating shaft 11. While the first rotating shaft 11 rotates, it drives the eccentric shaft 8, and the eccentric shaft 8 rotates at high speed through the cooperation of the first limiting sleeve 9 and the second limiting sleeve 10. While the eccentric shaft 8 rotates at high speed, the vibration sleeve 4 generates high-frequency vibration due to centrifugal force, thereby causing the vibration sleeve 4 to vibrate the concrete at high frequency.

[0030] As Figure 4As shown in the figure, the speed increasing mechanism 12 includes: on the outer surface of the top end of the first rotating shaft 11, first gears 13 are fixedly connected. Between the two first gears 13, a second gear 14 is arranged. At the center of the second gear 14, a second rotating shaft 15 is fixedly connected. The top end of the second rotating shaft 15 penetrates through the gear box 2 and extends to the outside of the gear box 2. The second rotating shaft 15 is rotatably connected with the gear box 2. The first gears 13 are all meshed with the second gear 14. On the outer surface of the top end of the second rotating shaft 15, a first synchronous pulley 16 is fixedly connected. On one side of the first synchronous pulley 16, a second synchronous pulley 17 is arranged. At the center of the second synchronous pulley 17, a third rotating shaft 18 is fixedly connected. The bottom end of the third rotating shaft 18 is rotatably connected with the gear box 2. At the top end of the third rotating shaft 18, a first motor 19 is arranged. The first motor 19 is fixedly connected with the gantry 3. The third rotating shaft 18 is fixedly connected with the output end of the first motor 19. The first synchronous pulley 16 and the second synchronous pulley 17 are connected by a synchronous belt 31. Start the first motor 19. The output end of the first motor 19 drives the third rotating shaft 18. The third rotating shaft 18 drives the second synchronous pulley 17. The second synchronous pulley 17 drives the first synchronous pulley 16 through the synchronous belt 31. While the first synchronous pulley 16 rotates, it drives the second rotating shaft 15. The second rotating shaft 15 drives the second gear 14. The second gear 14 simultaneously drives the first gears 13 on both sides. The first gears 13 drive the first rotating shaft 11 to rotate at a high speed.

[0031] As Figure 5 As shown in the figure, the leveling mechanism 7 includes: inside the gantry 3, a connecting frame 20 is fixedly connected. Inside the connecting frame 20, a reciprocating lead screw 21 is arranged. One end of the reciprocating lead screw 21 is rotatably connected with the frame 1. The other end of the reciprocating lead screw 21 penetrates through the frame 1 and extends to the second motor 22. The second motor 22 is fixedly connected with the frame 1. The reciprocating lead screw 21 is fixedly connected with the output end of the second motor 22. Near the reciprocating lead screw 21 of the connecting frame 20, a fourth rotating shaft 23 is rotatably connected. At the bottom end of the fourth rotating shaft 23, a rhombic block 24 is fixedly connected. The rhombic block 24 is adapted to the reciprocating lead screw 21. Start the second motor 22. The output end of the second motor 22 drives the reciprocating lead screw 21 to rotate. While the reciprocating lead screw 21 rotates, it pushes the rhombic block 24 through the reciprocating spiral groove on the surface. The rhombic block 24 moves horizontally through the cooperation of the fourth rotating shaft 23. While the rhombic block 24 moves, it drives the connecting frame 20 through the fourth rotating shaft 23. The connecting frame 20 drives the gantry 3. The gantry 3 drives the gear box 2, so that the gear box 2 makes a reciprocating horizontal movement inside the frame 1. While the gear box 2 moves, it drives the scraper 5. Furthermore, the scraper 5 levels the surface of the concrete multiple times reciprocally, which can level the surface of the concrete multiple times, improve the flatness of the surface of the concrete after leveling, and solve the problem that the existing ground leveling device for concrete construction cannot level the surface of the concrete reciprocally, resulting in poor flatness of the surface of the concrete after leveling.

[0032] AsFigure 3 As shown, limit sliders 25 are fixedly connected to both sides of the gantry 3. Slide bars 26 are slidably connected inside the limit sliders 25, and both ends of the slide bars 26 are fixedly connected to the frame 1, which can limit the gantry 3 and enable the gantry 3 to slide horizontally inside the frame 1.

[0033] As Figure 7 As shown, sleeves 27 are fixedly connected to the four corners of the bottom of the frame 1. Hydraulic cylinders 28 are fixedly connected inside the sleeves 27. The telescopic ends of the hydraulic cylinders 28 are fixedly connected with support blocks 29. When the hydraulic cylinders 28 are started, the overall height of the frame 1 is controlled through the cooperation of the support blocks 29 while the telescopic ends of the hydraulic cylinders 28 extend and retract, thereby achieving the control of the height of the scraper 5 to facilitate the scraping of the surface of the concrete by the scraper 5.

[0034] As Figure 7 As shown, damping pads 30 are arranged at the bottoms of the support blocks 29, and the damping pads 30 are fixedly connected to the support blocks 29 respectively, which increases the friction between the support blocks and the ground and thus improves the stability of the device.

[0035] Working principle: The user starts the hydraulic cylinder 28. While the telescopic end of the hydraulic cylinder 28 extends and retracts, the overall height of the frame 1 is controlled through the cooperation of the support block 29, thereby causing the scraper 5 to descend to the surface of the concrete. At the same time, the vibration sleeve 4 is inserted into the interior of the concrete. The first motor 19 is started. The output end of the first motor 19 is the third rotating shaft 18. The third rotating shaft 18 drives the second synchronous wheel 17. The second synchronous wheel 17 drives the first synchronous wheel 16 through the synchronous belt 31. While the first synchronous wheel 16 rotates, it drives the second rotating shaft 15. The second rotating shaft 15 drives the second gear 14. The second gear 14 simultaneously drives the first gears 13 on both sides. The first gears 13 drive the first rotating shaft 11 to rotate at a high speed. While the first rotating shaft 11 rotates, it drives the eccentric shaft 8. The eccentric shaft 8 rotates at a high speed through the cooperation of the first limit sleeve 9 and the second limit sleeve 10. While the eccentric shaft 8 rotates at a high speed, due to the centrifugal force, the vibration sleeve 4 generates high-frequency vibrations, thereby causing the vibration sleeve 4 to vibrate the concrete at a high frequency. It is possible to insert the vibration sleeve 4 deep into the concrete while the device levels the concrete. By vibrating, the fluidity of the concrete is improved, and thus the air bubbles in the concrete are discharged, solving the problem that due to the poor fluidity of the concrete, there are a large number of air bubbles inside it, and the existing ground leveling devices for concrete construction cannot discharge the air bubbles inside the concrete, resulting in a low ground strength after the concrete solidifies due to a large number of pores inside.

[0036] Start the second motor 22. The output end of the second motor 22 drives the reciprocating lead screw 21 to rotate. While the reciprocating lead screw 21 rotates, it pushes the diamond-shaped block 24 through the surface reciprocating spiral groove. The diamond-shaped block 24 moves horizontally through the cooperation of the fourth rotating shaft 23. While the diamond-shaped block 24 moves, it drives the connecting frame 20 through the fourth rotating shaft 23. The connecting frame 20 drives the gantry 3, and the gantry 3 drives the gearbox 2, so that the gearbox 2 makes a reciprocating horizontal movement inside the frame 1. While the gearbox 2 moves, it drives the scraper 5, and further makes the scraper 5 scrape the surface of the concrete repeatedly. The surface of the concrete can be scraped flat multiple times, improving the flatness of the surface of the concrete scraped, and solving the problem that the existing ground leveling device for concrete construction cannot reciprocally scrape the surface of the concrete, resulting in poor flatness of the surface of the concrete after scraping.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
