[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, a concrete pavement leveling device includes a support template 1, which is disposed on both sides of the concrete pavement. It also includes: a positioning mechanism 2 slidably connected to the support template 1; a height adjustment mechanism 3 disposed on the top of the positioning mechanism 2; a height limiting rod 4 detachably connected to the top of the height adjustment mechanism 3; a mover 5 slidably connected to the height limiting rod 4; and a vibrating leveling ruler 6 fixedly connected to the mover 5.

[0024] The preferred support template 1 is an aluminum film. If the aluminum film is insufficient, a wooden template can also be selected. The top thickness of the support template 1 is required to be greater than 10cm. The elevation of the top surface of the support template 1 is measured and recorded after it is erected.

[0025] like Figure 2 As shown, the positioning mechanism 2 includes a horizontal plate 21 and a vertical plate 22. The top of the vertical plate 22 passes through the horizontal plate 21. The vertical plate 22 is slidably connected to the rear of the horizontal plate 21. A reaction plate 211 is provided on the horizontal plate 211. A spring 23 is provided on the reaction plate 211. The other end of the spring 23 is fixed to the top of the horizontal plate 21. The spring 23 pulls the vertical plate 22 to move towards the reaction plate 211, thereby making the vertical plate 22 tend to move closer to the support template 1.

[0026] The horizontal plate 21 is equipped with two first rollers 212, which, under the action of gravity, are in contact with the top surface of the support template 1 and move on the top of the support template 1. The vertical plate 22 is equipped with two second rollers 221, which move along the side wall of the support template 1. Due to the pull of the spring 23, the vertical plate 22 moves towards the support template 1, and the second rollers 221 are in contact with the side of the support template 1. The low friction between the first rollers 212 and the second rollers 221 facilitates the movement of the horizontal plate 21 and the vertical plate 22 on the support template 1.

[0027] The height adjustment mechanism 3 includes a hollow threaded column 31, a sliding rod 32, and a positioning nut 33. The outer wall of the hollow threaded column 31 is provided with external threads. The sliding rod 32 is slidably connected to the hollow threaded column 31. The positioning nut 33 is screwed to the hollow threaded column 31 and is located below the sliding rod 32. The top of the sliding rod 32 is provided with a support block 321, which is used to support the height limiting rod 4 and fix the height limiting rod 4 at a predetermined height.

[0028] The hollow threaded column 31 has a vertical slide rail 311 on its side wall, which penetrates the side wall of the hollow threaded column 31, thereby connecting the inside and outside of the hollow threaded column 31. A limiting rod 322 is fixedly connected to the bottom of the sliding rod 32. The limiting rod 322 is perpendicular to the sliding rod 32, with the sliding rod 32 pointing vertically and the limiting rod 322 pointing horizontally. The limiting rod 322 passes through the vertical slide rail 311, and its outer end is outside the hollow threaded column 31. A positioning nut 33 supports the limiting rod 322 and prevents the limiting rod 322 from sliding downward. By rotating the positioning nut 33, its height can be changed, thereby adjusting the height of the sliding rod 32 and the height limiting rod 4. There are two positioning nuts 33, which fit together. The lower positioning nut 33 further stabilizes the position of the upper positioning nut 33.

[0029] like Figure 3 As shown, the height restriction pole 4 includes an end pole 41, a middle pole 42, and a splicing pole 43. A sliding rod 32 passes through the end pole 41, and the end of the end pole 41 is attached to the support block 321. Multiple splicing poles 43 are detachably connected. The overall length of the height restriction pole 4 can be changed by connecting multiple splicing poles 43, thereby allowing the height restriction pole 4 to adapt to the width of the concrete pavement. The splicing pole 43 is located between the middle pole 42 and the end pole 41, and splicing poles 43 can be connected to both sides of the middle pole 42.

[0030] One end of the splicing rod 43 is provided with a insertion hole 45, and the other end of the splicing rod 43 is provided with a insertion block 44. The insertion block 44 can be inserted into the insertion hole 45 of the adjacent splicing rod 43. A positioning pin 46 can be inserted into the insertion hole 45. The positioning pin 46 can vertically penetrate the insertion block 44, thereby preventing the insertion block 44 from detaching from the insertion hole 45. The two ends of the positioning pin 46 do not protrude from the surface of the height limiting rod 4, and do not affect the sliding of the mover 5. The end of the end rod 41 is provided with an insertion block 44, and the two ends of the middle rod 42 are provided with insertion holes 45. When the end rod 41 is connected to the splicing rod 43, the insertion block 44 of the end rod 41 is inserted into the insertion hole 45 of the splicing rod 43. When the middle rod 42 is connected to the splicing rod 43, the insertion block 44 of the splicing rod 43 is inserted into the insertion hole 45 of the middle rod 42.

[0031] like Figure 4 As shown, the mover 5 moves on the height-limiting rod 4. The mover 5 includes a C-shaped shell 51, a pin 52, and a third roller 53. The height-limiting rod 4 passes through the C-shaped shell 51. The third roller 53 is located on the inner wall of the rear end of the C-shaped shell 51 and fits against the side wall of the height-limiting rod 4. The pin 52 passes through the front end of the C-shaped shell 51. When installing the height-limiting rod 4, the pin 52 is removed, creating an opening in the side wall of the C-shaped shell 51. The height-limiting rod 4 is then inserted into the C-shaped shell 51 through the opening, ensuring that the side wall of the height-limiting rod 4 is tightly fitted against the third roller 53. Afterward, the pin 52 is inserted into the front end of the C-shaped shell 51, thereby preventing the C-shaped shell 51 from detaching from the height-limiting rod 4.

[0032] Two movers 5 are provided, and a connecting rod 7 is fixed between the side walls of the two C-shaped shells 51. The two movers 5 move synchronously.

[0033] The vibratory leveling ruler 6 is fixedly connected to the C-shaped shell 51 and fits against the concrete pavement. The bottom height of the vibratory leveling ruler 6 is adjusted by the height adjustment mechanism 3. The bottom height of the vibratory leveling ruler 6 is the design elevation of the pavement. After the vibratory leveling ruler 6 is activated, it can push the concrete that is higher than the design elevation to a place lower than the design elevation, thus leveling the concrete pavement. The vibratory leveling ruler 6 can be moved left and right by the height limit bar 4 and moved back and forth by pushing the positioning mechanism 2, thereby enabling the vibratory leveling ruler 6 to move at the same elevation, improving the leveling efficiency and eliminating the need for real-time measurement and control during the leveling process.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
