Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge surface construction leveling device. Background Art

[0002] A bridge is a structure that connects two banks or crosses obstacles (such as rivers, canyons, roads, etc.). It is mainly used for transportation. The leveling device in the construction of the bridge surface is an important tool to ensure the flatness and uniform thickness of the bridge surface.

[0003] In order to enable the leveling device to adapt to the slope and curvature of the bridge deck, the bridge construction leveling device generally adopts a roller structure, and the concrete of the bridge deck is compacted and leveled by rolling the roller back and forth on the bridge deck. However, the length of the roller of the existing leveling device is fixed. In actual use, the length of the roller cannot be adjusted according to the construction width of the bridge deck, resulting in poor adaptability of the leveling device and low flexibility in use.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A bridge surface construction leveling device comprises a U-shaped load-bearing bracket, a leveling roller is rotatably installed on the inner side of the U-shaped load-bearing bracket, two connecting plates are fixedly installed on the surface of one side of the U-shaped load-bearing bracket, a hollow cylinder penetrating the connecting plates is fixedly installed between the surfaces of the two opposite sides of the two connecting plates, two internal threaded cylinders are fixedly installed inside the hollow cylinder, a threaded rod extending to the outside of the hollow cylinder is threadedly connected to the internal thread of the internal threaded cylinder, a mounting shaft is fixedly installed on one end of the threaded rod extending to the outside of the hollow cylinder, and an auxiliary extension roller is rotatably installed on the outer surface of the mounting shaft.

[0007] Furthermore, a limiting circular block is fixedly mounted on one end of the threaded rod away from the mounting shaft, and the limiting circular block is slidably arranged inside the hollow cylinder.

[0008] Furthermore, circular holes are formed at both ends of the hollow cylinder, the threaded rod is located inside the circular holes, and the diameter of the circular holes is larger than the outer diameter of the threaded rod.

[0009] Furthermore, a rubber telescopic dust cover is rotatably mounted between the surface of the hollow cylinder and the auxiliary extension roller on one side opposite to the auxiliary extension roller, and the threaded rod and the round hole are both located on the inner side of the rubber telescopic dust cover.

[0010] Furthermore, a rotating block with anti-slip grooves engraved on its side surface is fixedly installed at one end of the installation shaft away from the threaded rod, and the rotating block is rotatably connected to one end of the auxiliary extension roller away from the threaded rod.

[0011] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0012] In this bridge surface construction leveling device, an auxiliary extension roller adjusted by a threaded rod and an internal thread cylinder is provided on the U-shaped bearing bracket. During use, the overall length sum between the two auxiliary extension rollers and the leveling roller can be adjusted according to the specific width of the bridge deck, so that the overall length sum between the two auxiliary extension rollers and the leveling roller is adapted to the width of the bridge deck. Furthermore, the leveling device can be adapted to bridge decks of different widths, solving the problem that the lengths of the rollers of the existing leveling devices are fixed and the lengths of the rollers cannot be adjusted according to the construction width of the bridge deck during actual use, resulting in poor adaptability of the leveling device and low flexibility in use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] 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.

[0018] Please refer to Figures 1 to 3, A bridge surface construction leveling device in this embodiment includes a U-shaped bearing bracket 1. A leveling roller 2 is rotatably installed inside the U-shaped bearing bracket 1. On one side surface of the U-shaped bearing bracket 1, two connecting plates 3 are fixedly installed. Between the opposite side surfaces of the two connecting plates 3, a hollow cylinder 4 penetrating through the connecting plates 3 is fixedly installed. Inside the hollow cylinder 4, two internal thread cylinders 5 are fixedly installed. A threaded rod 6 extending to the outside of the hollow cylinder 4 is threadedly connected inside the internal thread cylinder 5. One end of the threaded rod 6 extending to the outside of the hollow cylinder 4 is fixedly installed with a mounting shaft 7. An auxiliary extension roller 8 is rotatably installed on the outer surface of the mounting shaft 7. One end of the mounting shaft 7 away from the threaded rod 6 is fixedly installed with a rotating block 12 with anti-slip grooves engraved on its side surface. The rotating block 12 is rotatably connected to one end of the auxiliary extension roller 8 away from the threaded rod 6. By setting the rotating block 12, it is convenient to rotate the threaded rod 6 and the mounting shaft 7, and it is convenient to adjust the length of the threaded rod 6 inside the hollow cylinder 4.

[0019] Specifically, one end of the threaded rod 6 away from the mounting shaft 7 is fixedly installed with a limiting circular block 9, and the limiting circular block 9 is slidably arranged inside the hollow cylinder 4. By setting the limiting circular block 9 on the threaded rod 6, the separation between the threaded rod 6 and the internal thread cylinder 5 can be prevented.

[0020] Specifically, circular holes 10 are opened at both ends of the hollow cylinder 4. The threaded rod 6 is located inside the circular holes 10. The diameter of the circular holes 10 is larger than the outer diameter of the threaded rod 6. By providing the circular holes 10 on the surface of the hollow cylinder 4, the threaded rod 6 can rotate more smoothly during the rotation process, which is convenient for the threaded rod 6 to expand and contract and move on the hollow cylinder 4. A rubber telescopic dust-proof sleeve 11 is rotatably installed between the opposite side surfaces of the hollow cylinder 4 and the auxiliary extension roller 8. The threaded rod 6 and the circular holes 10 are both located inside the rubber telescopic dust-proof sleeve 11. By setting the rubber telescopic dust-proof sleeve 11, the part of the threaded rod 6 extending to the outside of the hollow cylinder 4 can be protected, the surface of the threaded rod 6 can be prevented from being contaminated with impurities, and at the same time, the circular holes 10 can be closed, which is beneficial to preventing sundries from entering the hollow cylinder 4 through the circular holes 10.

[0021] The working principle of the above embodiment is as follows:

[0022] When in use, the mounting shaft 7 and the threaded rod 6 are rotated through the rotating block 12, so that the threaded rod 6 rotates inside the internal thread cylinder 5. When the threaded rod 6 moves towards the outside of the hollow cylinder 4, the auxiliary extension roller 8 moves towards the end away from the hollow cylinder 4 following the threaded rod 6. Furthermore, the distance between the ends of the two auxiliary extension rollers 8 away from the hollow cylinder 4 and the end of the leveling roller 2 increases, and thus the leveling width of the leveling device can be increased.
