[0049] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0050] Embodiment 1

[0051] Figures 1-5 The structural diagram of a leveling device 100 for an airport prefabricated pavement slab 101 according to an embodiment of the present application is shown. As Figures 1-5 shown, the leveling device 100 may include:

[0052] A sleeve assembly 110. There are several through holes 111 at the edge of the pavement slab 101, and the sleeve assembly 110 is inserted into the through holes 111;

[0053] A collar assembly 120. The collar assembly 120 is arranged on the sleeve assembly 110. The collar assembly 120 is movable relative to the sleeve assembly 110. There is a spacing between the collar assemblies 120, and the spacing between the collar assemblies 120 is the same as the thickness of the pavement slab 101;

[0054] A limiting assembly 130. The limiting assembly 130 is arranged on the sleeve assembly 110 to fix the position of the collar assembly 120 relative to the sleeve assembly 110;

[0055] A support assembly 140. The support assembly 140 is adjustably arranged at the bottom of the sleeve assembly 110, and the support assembly 140 supports the bottom of the pavement slab 101.

[0056] In this embodiment, according to the thickness of the pavement slab 101, the position of the collar assembly 120 relative to the sleeve assembly 110 is adjusted so that the distance between the collar assemblies 120 is the same as the thickness of the pavement slab 101. After the adjustment is completed, the position of the collar assembly 120 is fixed relative to the sleeve assembly 110 through the limiting assembly 130. The support assembly 140 is installed at the lower part of the sleeve assembly 110. After the installation is completed, the sleeve assembly 110 is installed in the through hole 111 so that the support assembly 140 supports the pavement slab 101. When the surface of the pavement slab 101 is inclined, a screwdriver is inserted through different sleeve assemblies 110 to adjust the position of the support assembly 140 relative to the sleeve assembly 110 so that the surface of the pavement slab 101 is horizontal. After the adjustment is completed, grout is poured into the sleeve assembly 110 to fill the hollow part at the bottom of the pavement slab 101;

[0057] By movably arranging the collar assembly 120 on the sleeve assembly 110, the collar assembly 120 can be adjusted according to the thickness of the road slab 101, so that the leveling device 100 can adapt to more road slabs 101 with different thicknesses, saving costs and improving the adaptability of the leveling device 100. By adjusting the distances between the support assemblies 140 at different positions and the road slab 101, the road slab 101 to be leveled can be leveled, avoiding tilting when the road slab 101 is placed due to ground unevenness, and ensuring that the flatness of the road slab 101 after assembly meets the design requirements.

[0058] As Figure 1 and Figure 5 shown, in one embodiment,

[0059] The sleeve assembly 110 includes:

[0060] The upper sleeve 112 has a first groove 114 and a plurality of second grooves 115 thereon. The first groove 114 is vertically arranged on the upper sleeve 112, and the second grooves 115 are vertically arranged on the upper sleeve 112. A plurality of second grooves 115 are all communicated with the first groove 114;

[0061] The lower sleeve 113 is threadedly connected to the upper sleeve 112. When the upper sleeve 112 and the lower sleeve 113 are connected, the upper sleeve 112 and the lower sleeve 113 are inserted into the through hole 111. Part of the collar assembly 120 is provided on both the upper sleeve 112 and the lower sleeve 113.

[0062] In this embodiment, the arrangement shape of the first groove 114 and the plurality of second grooves 115 is similar to an "E" shape. Both the upper sleeve 112 and the lower sleeve 113 have threads, and the upper sleeve 112 and the lower sleeve 113 are threadedly connected. After the collar assembly 120 on the upper sleeve 112 is adjusted, the upper sleeve 112 and the lower sleeve 113 are respectively inserted into the through hole 111, and the upper sleeve 112 and the lower sleeve 113 are connected through the threads on the upper sleeve 112 and the lower sleeve 113, which is convenient for the installation of the upper sleeve 112 and the lower sleeve 113. When the upper sleeve 112 and the lower sleeve 113 are connected, the collar assembly 120 on the upper sleeve 112 fits with the surface of the road slab 101 and remains flush with the surface of the road slab 101, and the collar assembly 120 on the lower sleeve 113 fits with the bottom surface of the road slab 101 and remains flush with the bottom surface of the road slab 101;

[0063] Further, when the part of the collar assembly 120 located on the upper sleeve 112 is in contact with the road panel 101, and the part of the collar assembly 120 located on the lower sleeve 113 is in contact with the road panel 101, if the threaded connection between the upper sleeve 112 and the lower sleeve 113 has not reached the limit at this time, the rotation of the upper sleeve 112 or the lower sleeve 113 can be stopped. Taking the surface contact between the collar assembly 120 and the road panel 101 as the final installation reference, the distance between the collar assemblies 120 can also be finely adjusted.

[0064] As Figures 1-3 shown, in one embodiment,

[0065] The limiting component 130 includes:

[0066] A plurality of limiting marbles 131, and the plurality of limiting marbles 131 are all arranged on the upper sleeve 112, and at least two limiting marbles 131 are arranged in each second groove 115.

[0067] In this embodiment, the limiting marbles 131 are arranged on the upper sleeve 112, and the collar assembly 120 is limited by the limiting marbles 131 so that the position of the collar assembly 120 relative to the upper sleeve 112 is fixed.

[0068] As Figures 1-3 and Figure 5 shown, in one embodiment,

[0069] The collar assembly 120 includes:

[0070] An upper collar 121, which is movably arranged on the upper sleeve 112, the upper collar 121 is in contact with the surface of the road panel 101, the upper collar 121 has a first state and a second state. When the upper collar 121 is in the first state, the upper collar 121 is located in the first groove 114. When the upper collar 121 is in the second state, the upper collar 121 is located in any one of the second grooves 115;

[0071] A lower collar 122, which is fixedly connected to the lower sleeve 113, and the lower collar 122 is in contact with the road panel 101.

[0072] In this embodiment, the upper collar 121 has a convex block 123. The first state of the upper sleeve 112 is the adjustment state, at this time the upper sleeve 112 slides in the first groove 114. The second state of the upper sleeve 112 is the fixed state, at this time the convex block 123 on the upper sleeve 112 is located in one of the second grooves 115. By switching the upper collar 121 in the second grooves 115 at different heights, the distance between the upper collar 121 and the lower collar 122 is changed, so that the upper sleeve and the lower sleeve can be matched with road panels 101 of different thicknesses;

[0073] The width of the first groove 114 is adapted to the width of the bump 123, and the second groove 115 is adapted to the shape of the bump 123.

[0074] As Figures 1-3 shown, in one embodiment,

[0075] The upper collar 121 has a bump 123, and the bump 123 has a card slot 124 adapted to the shape of the limit marble 131. When the upper collar 121 is in the second state, the limit marble 131 is located in the card slot 124 to fix the position of the upper collar 121.

[0076] In this embodiment, when the upper collar 121 is located in the second groove 115, the limit marble 131 is located in the card slot 124 on the bump 123 to fix the position of the upper collar 121 relative to the upper sleeve 112. When the upper collar 121 needs to be adjusted again, just rotate the upper collar 121 in the reverse direction to make the limit marble 131 escape from the card slot 124, and the upper collar 121 can be reset from the second groove 115 back to the first groove 114.

[0077] As Figure 1 and Figure 5 shown, in one embodiment,

[0078] The support assembly 140 includes:

[0079] A support column 141, which is threadedly connected to the lower sleeve 113;

[0080] A base 142, which is located at one end of the support column 141 away from the lower sleeve 113. By rotating the support column 141, the distance between the base 142 and the road surface panel 101 can be changed to keep the surface of the road surface panel 101 horizontal.

[0081] In this embodiment, the surface of the support column 141 has an external thread, and the inner wall of the lower collar 122 has an internal thread adapted to the external thread. When the road surface panel 101 is placed on an uneven ground, it is easy for the surface of the road surface panel 101 to be inclined when it fits with the base layer by its own gravity. Through the arrangement of the upper sleeve 112 and the lower sleeve 113, when the support column 141 jacks up the lower sleeve 113, the diameter of the lower collar 122 is greater than the diameter of the through hole 111, so that the lower collar 122 lifts the road surface panel 101. By changing the distance between the support column 141 and the lower collar 122, the base 142 can adjust different positions of the road surface panel 101 to make the surface flatness (horizontal) of the road surface panel 101.

[0082] As Figure 1 shown, in one embodiment,

[0083] One end of the support column 141 located inside the lower sleeve 113 has a cross groove 143.

[0084] In this embodiment, a cross groove 143 is provided on the support column 141, which facilitates adjusting the position of the support column 141 relative to the lower sleeve 113 by an electric screwdriver, thereby changing the length of the support column 141 extending out of the lower sleeve 113, so as to support the road surface slab 101 at different sunken positions and ensure the flatness (horizontal) of the surface of the road surface slab 101.

[0085] As Figure 1 and Figure 5 shown, in one implementation,

[0086] The support column 141 has a grouting hole; the upper sleeve 112 has a grouting hole to facilitate grouting between the upper sleeve 112, the lower sleeve 113 and the through hole 111.

[0087] In this embodiment, after the adjustment is completed, the upper sleeve 112 is removed, and grouting is carried out into the lower sleeve 112 from the through hole 111. The grout enters between the lower sleeve 113 and the through hole 111, and at the same time enters the bottom of the road surface slab 101 through the grouting hole on the support column 141 to fill the uneven ground, so that the bottom of the road surface slab 101 is filled to ensure that the road surface slab 101 will not sink during subsequent use;

[0088] Removing the upper sleeve 112 for grouting can ensure the flatness of the surface of the road surface slab 101;

[0089] When needed, grouting can also be carried out on the upper sleeve 112 at the same time.

[0090] Embodiment 2

[0091] The difference compared with Embodiment 1 is that

[0092] In this embodiment, the first groove 114 and several second grooves 115 are both provided on the lower sleeve 113. The lower collar 122 is movably arranged on the lower sleeve 113. The lower sleeve 113 has a first groove 114 and several second grooves 115. The lower collar 122 has a convex block 123. The lower sleeve 113 has a first state and a second state.

[0093] For the functions of the modules in each device in the embodiments of the present utility model, reference can be made to the corresponding descriptions in the above methods, which will not be elaborated here.

[0094] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present application.
