DETAILED DESCRIPTION

[0024] The following will be described in detail in combination with the accompanying drawings. Figures 1-6 The application is further described in detail.

[0025] The embodiment of the application discloses a large-area concrete pouring precision leveling device, which comprises a multi-dimensional vibration mechanism 30, and the multi-dimensional vibration mechanism 30 comprises a pneumatic pump 31, a pneumatic conveying pipe 32, a seven-way air pipe joint one 33, a seven-way air pipe joint two 34, two groups of three-way air pipe joints 35, two groups of vibration pipes 36, two linkage plates 38, a plurality of butt joint connecting pipes 314 and two electric cylinders 311.

[0026] The pneumatic output end of the pneumatic pump 31 is fixedly connected in communication with one end of the pneumatic conveying pipe 32, and the other end of the pneumatic conveying pipe 32 is a two-port, the two ports of the pneumatic conveying pipe 32 are respectively in threaded communication with each one-way pipe of the seven-way air pipe joint one 33 and the seven-way air pipe joint two 34, each of the other six-way pipes of the seven-way air pipe joint one 33 and the seven-way air pipe joint two 34 is in threaded communication with the pneumatic connecting pipe 313, the other end of the pneumatic connecting pipe 313 in communication with the seven-way air pipe joint one 33 and the seven-way air pipe joint two 34 is respectively in threaded communication with one-way pipes in the two groups of three-way air pipe joints 35, the two-way pipes in the two groups of three-way air pipe joints 35 are butt jointed in communication through the plurality of butt joint connecting pipes 314, the three-way pipes in the two groups of three-way air pipe joints 35 are respectively fixedly connected with the two groups of vibration pipes 36, the two groups of vibration pipes 36 are respectively fixedly connected to the two linkage plates 38, the outer walls of the two groups of vibration pipes 36 are annularly fixedly connected with a plurality of vibration claws 37, the outer walls of the vibration claws 37 are conically arranged, the output shafts of the two electric cylinders 311 are fixedly connected with the supporting plates 312, and the other sides of the two supporting plates 312 are respectively fixed to the two linkage plates 38.

[0027] The stepped vibration mechanism 40 is installed on the two sides and the middle part of the multi-dimensional vibration mechanism 30.

[0028] As Figure 3 shown in the figure, the stepped vibration mechanism 40 comprises a narrow leveling vibration table one 41, a narrow leveling vibration table two 42, three groups of small vibrators 43, two fixed plates one 44, a wide leveling vibration table 45, four groups of large vibrators 46, a fixed plate two 47 and a leveling fixed table 48;

[0029] The leveling fixed table 48 is provided with a through groove 49 on both sides, and the two linkage plates 38 are respectively slidingly connected to the inside of the through groove 49. The narrow leveling vibration table one 41 and the narrow leveling vibration table two 42 are arranged on both sides of the wide leveling vibration table 45. The inner bottom wall of the narrow leveling vibration table one 41 and the narrow leveling vibration table two 42 is uniformly and equidistantly bolted with three groups of small vibrators 43. The bottom of the two electric cylinders 311 is symmetrically bolted to the top of the leveling fixed table 48. The inner bottom wall of the wide leveling vibration table 45 is uniformly and equidistantly bolted with four groups of large vibrators 46. By starting the small vibrators 43 and the large vibrators 46, which are respectively located on the narrow leveling vibration table one 41, the narrow leveling vibration table two 42 and the wide leveling vibration table 45, the vibrator starts to generate vibration force, which is transmitted to the concrete surface through the narrow leveling vibration table one 41, the narrow leveling vibration table two 42 and the wide leveling vibration table 45. In the beginning and ending sections, the narrow leveling vibration table one 41 and the narrow leveling vibration table two 42 generate relatively small vibration to ensure the flatness of the concrete surface. In the middle, the wide leveling vibration table 45 generates greater vibration force to penetrate into the concrete interior and improve the vibration effect. The stepped vibration mechanism 40 generates a layered vibration effect through different parts of the vibrator and the vibration table, and ensures that the entire surface is properly vibrated.

[0030] As Figure 3 shown in the figure, the two fixed plates one 44 are respectively fixedly connected to the top middle part of the narrow leveling vibration table one 41 and the narrow leveling vibration table two 42. The narrow leveling vibration table one 41 and the narrow leveling vibration table two 42 are respectively fixedly connected to the bottom two sides of the leveling fixed table 48 through the two fixed plates one 44. The fixed plate two 47 is fixedly connected to the top middle part of the wide leveling vibration table 45. The wide leveling vibration table 45 is fixedly connected to the bottom middle part of the leveling fixed table 48 through the fixed plate two 47. The narrow leveling vibration table one 41, one group of vibration pipes 36, the wide leveling vibration table 45, another group of vibration pipes 36 and the narrow leveling vibration table two 42 are sequentially installed on the bottom of the leveling fixed table 48.

[0031] As Figure 2As shown, the top side of the leveling fixing table 48 is provided with a lifting mechanism 20, which comprises two vertical columns 21, a cross beam 22, a lifting cylinder 23, a lifting slide 24, a base 25 and a linkage fixing table 26. The top of the two vertical columns 21 is fixedly connected with the cross beam 22, and the bottom of the two vertical columns 21 is fixedly connected to the top of the base 25. The cylinder barrel of the lifting cylinder 23 is installed at the bottom of the cross beam 22, and the output shaft of the lifting cylinder 23 is fixedly connected to the top of the lifting slide 24. The lifting slide 24 is slidingly connected to the outer wall of the two vertical columns 21. One side of the linkage fixing table 26 is bolted to the adjacent side of the lifting slide 24, and the bottom of the linkage fixing table 26 is fixedly connected to the top middle part of the leveling fixing table 48. The operator can control the extension and retraction of the lifting cylinder 23. When the lifting cylinder 23 extends and retracts, the lifting slide 24 moves up and down. The movement of the lifting slide 24 synchronizes the position of the linkage fixing table 26, and then drives the lifting movement of the leveling fixing table 48 through the up and down movement of the lifting slide 24.

[0032] As shown in Figure 1 The side of the lifting mechanism 20 is provided with a driving vehicle body 10, and the bottom of the base 25 in the lifting mechanism 20 is fixedly installed on the rear side of the driving vehicle body 10. The control console of the driving vehicle body 10 is provided with a controller 11. The driving vehicle body 10 is located on one side of the lifting mechanism 20, which is used to provide additional stability and balance, and helps to ensure the stable operation of the lifting mechanism 20. At the same time, the controller 11 is integrated into the control console of the driving vehicle body 10, so as to facilitate the operator to control.

[0033] The implementation principle of the large-area concrete pouring precision leveling device according to the embodiment of the present application is as follows:

[0034] Through the controller 11, the operator can control the extension and retraction of the lifting cylinder 23, drive the lifting slide 24 to move up and down when the lifting cylinder 23 extends and retracts, the movement of the lifting slide 24 will synchronize the position of the linkage fixed platform 26, and then drive the leveling fixed platform 48 to move up and down through the up and down movement of the lifting slide 24, when it is needed to go deep into the concrete, the operator will extend and retract the lifting cylinder 23 to make the leveling fixed platform 48 sink; on the contrary, when it is needed to vibrate shallowly, the leveling fixed platform 48 can be lifted, the multi-dimensional vibration mechanism 30 is placed in the engineering area where concrete pouring and leveling is needed, the ladder vibration mechanism 40 at the bottom of the leveler is in the position of contacting the surface of the concrete, and the position of the multi-dimensional vibration mechanism 30 and the ladder vibration mechanism 40 and the concrete leveling plane is controlled through the lifting mechanism 20;Specifically, the air pressure of the pneumatic pump 31 is controlled by the controller 11 to control the vibration intensity. Increasing the air pressure will increase the vibration intensity, and decreasing the air pressure will decrease the vibration intensity. The pneumatic pump 31 is started to generate air pressure, which is transmitted to the seven-way air joint one 33 and the seven-way air joint two 34 through the pneumatic conveying pipe 32. The air pressure is redistributed to the two sets of three-way air joints 35 through the seven-way air joint one 33 and the seven-way air joint two 34. The two sets of three-way air joints 35 are symmetrically arranged and maintain the stability of the air pressure through the arc-shaped delivery pipe 314. The air pressure is transmitted to the vibration pipe 36, while maintaining the uniformity of the vibration. The vibration of the vibration pipe 36 can deeply penetrate the vibration force into the concrete, not only acting on the surface, but also affecting the deeper layer of the concrete, which helps to remove the bubbles in the concrete, improve the compactness, and improve the overall uniformity. The vibration force generated by the vibration of the vibration pipe 36 is transmitted to the surrounding vibration claws 37. The vibration claws 37 are protruding structures on the outer wall of the vibration pipe 36. When the vibration force is transmitted to the vibration claws 37, the vibration claws 37 vibrate. The outer wall of the vibration claws 37 is in the shape of a tapered vibration. The vibration force around the vibration claws 37 causes the surface of the concrete and the surrounding area to be uniformly vibrated, which helps to ensure that the entire concrete surface is uniformly vibrated, reducing unevenness and surface defects. The extension and retraction of the two electric cylinders 311 are controlled by the controller 11, and the supporting plate 312 can move up and down. This movement is transmitted to the linkage plate 38, thereby driving the vibration pipe 36 and the vibration claws 37 to move up and down. This up-and-down reciprocating motion enables the vibration force to deeply penetrate into the concrete, which helps to remove bubbles, improve compactness, and improve uniformity. By starting the small vibrator 43 and the large vibrator 46, which are respectively located on the narrow leveling vibration table one 41, the narrow leveling vibration table two 42, and the wide leveling vibration table 45, the vibrator starts to generate vibration force, which is transmitted to the surface of the concrete through the narrow leveling vibration table one 41, the narrow leveling vibration table two 42, and the wide leveling vibration table 45. In the beginning and ending sections, the narrow leveling vibration table one 41 and the narrow leveling vibration table two 42 generate relatively small vibrations to ensure the smoothness of the concrete surface. In the middle, the wide leveling vibration table 45 generates greater vibration force to deeply penetrate into the concrete and improve the vibration effect. The stepped vibration mechanism 40 generates a layered vibration effect through different parts of the vibrator and the vibration table, and ensures that the entire surface is properly vibrated without excessive or insufficient vibration, which helps to deeply penetrate into the concrete and improve the compactness. The work of the multi-dimensional vibration mechanism 30 is also carried out simultaneously to provide vibration in different directions. The two linkage plates 38 are respectively slidably connected in the through slot 49 of the leveling fixed table 48, which can ensure that the vibration screed moves smoothly during operation.

[0035] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Any equivalent changes made according to the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
