DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 1-2 As shown, the utility model provides a civil engineering construction leveling device, which includes a support frame 1, which is arranged in a rectangular frame. Connecting plates 2 are fixedly connected to both sides of the support frame 1 for dragging and connecting the two sides of the support frame 1. The utility model also includes a leveling mechanism 3, an adjustable separation mechanism 4 and a rolling assembly 5. The leveling mechanism 3 is fixedly connected to the middle of the relative inner walls of the support frame 1 for filling and vibration leveling. The adjustable separation mechanism 4 is arranged on both sides of the support frame 1. The adjustable separation mechanism 4 is symmetrically arranged with the leveling mechanism 3 as the center for pushing and leveling the mud potholes. The rolling assembly 5 is arranged on one side of the interior of the support frame 1. The rolling assembly is located between the leveling mechanism 3 and the adjustable separation mechanism 4 on one side for slow rolling leveling.
[0021] like Figure 1-3As shown, in order to initially flatten the poured concrete and make the uneven concrete surface flat, the adjustable partition mechanism 4 includes a positioning plate 12, a stud 13, a cross plate 14 and a partition plate 15. The positioning plate 12 is fixedly connected to the inner wall of one side of the support frame 1 close to the connecting plate 2. The positioning plate 12 is symmetrically arranged with the vibration shell 6 as the center. One end of the stud 13 penetrates the positioning plate 12 and is threadedly connected to the bottom of the positioning plate 12. Limit rods 16 are penetrated on both sides of the positioning plate 12. The limit rods 16 are arranged with the stud 13 as the center. The center is symmetrically arranged, the cross plate 14 is rotatably connected to the bottom wall of the stud 13 and fixedly connected to the limiting rod 16, the partition plate 15 is fixedly connected to the bottom wall of the cross plate 14, and the partition plates 15 are evenly spaced along the length direction of the cross plate 14. The height of the cross plate 14 is adjusted by rotating the stud 13. The limiting rod 16 is used to increase the connection stability of the cross plate 14, so that the evenly spaced partition plates 15 are in contact with the concrete and push the concrete along the moving direction of the device. The partition plates 15 are inserted into the concrete to flatten the concrete.
[0022] like Figure 1-4 As shown, in order to increase the leveling effect of concrete, the internal compaction of concrete is increased by vibration, and the missing parts are filled. The leveling mechanism 3 includes a vibration shell 6, a partition 7, a baffle 8 and a mud pump 9. The vibration shell 6 is arranged in a rectangular hollow cavity with an opening at the bottom. The vibration shell 6 is fixedly connected to the middle of the opposite inner wall of the support frame 1. The partition 7 is arranged in the vibration shell 6. The partition 7 is inclined. The baffle 8 is fixedly connected to the middle of the symmetrical partition 7. A storage cavity 10 is formed between the baffle 8 and the inner upper wall of the vibration shell 6. The mud pump 9 is arranged on the upper part of the vibration shell 6 and is connected to the storage cavity 10. A feed pipe 11 runs through the middle of the plate 8, and the storage chamber 10 is connected to the bottom opening of the vibration shell 6 through the feed pipe 11. The device as a whole keeps a horizontal moving state with the ground. During the movement, the arc-shaped edges on both sides of the bottom of the vibration shell 6 push the concrete surface. At the same time, the vibration motor 21 vibrates in the vibration shell 6 to vibrate the concrete to make its inside tight. The mud pump 9 draws external concrete and pumps it into the storage chamber 10, and discharges it from the middle of the bottom of the vibration shell 6 through the feed pipe 11, and vibrates again to fill the missing parts of the concrete surface, and then further rotates and contacts and smoothes it through the rolling component 5.
[0023] like Figure 2 and Figure 3As shown, in order to increase the flatness of the concrete surface and make the surface smooth after smoothing, the rolling assembly 5 includes a limit plate 17, a rotating roller 18 and a rotating motor 19. The limit plate 17 is fixedly connected to the bottom wall of the support frame 1, and the limit plate 17 is symmetrically arranged and distributed between the vibration shell 6 and the positioning plate 12 on one side. The rotating roller 18 is rotatably connected to the relatively inner wall of the symmetrical limit plate 17, and the rotating motor 19 is installed on the outer wall of the limit plate 17 on one side. The output end of the rotating motor 19 is connected to one end of the rotating roller 18. The rotating motor 19 drives the rotating roller 18 to rotate, so that the outer wall of the rotating roller 18 slowly rotates to contact the concrete surface, and rotates and rubs with the moisture on the concrete surface to make the concrete surface smoother.
[0024] Among them, the outer side wall of the support frame 1 is provided with a vertical pole 20, which is arranged in an N shape and is used for device hoisting and is also used for routing support of the mud pump 9 and the power line.
[0025] When in use, the operator connects the device to the rear of the mobile device through the connecting plate 2, rotates the stud 13, adjusts the height of the horizontal plate 14, and inserts the partition plate 15 into the concrete. When the device moves, the concrete is flattened;
[0026] After the initial flattening, the concrete interior and surface are further smoothed. The arc-shaped edges on both sides of the bottom of the vibration shell 6 are in contact with the concrete surface. The vibration motor 21 is started to vibrate inside the vibration shell 6 to vibrate the concrete at the bottom of the vibration shell 6 to make the inside compact. The mud pump 9 extracts the external concrete and pumps it into the storage chamber 10. The concrete is discharged from the middle of the bottom of the vibration shell 6 through the discharge pipe 11 and vibrates again to fill the missing parts of the concrete surface. Subsequently, the rolling assembly 5 is further rotated to contact and smoothen.
[0027] Finally, the rotating motor 19 is driven to drive the rotating roller 18 to rotate, so that the outer wall of the rotating roller 18 rotates slowly to contact the concrete surface, and rotates and rubs with the moisture on the concrete surface to make the concrete surface smoother.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
