Description

Technical Field

[0001] This utility model relates to waterproofing construction, specifically a rolling device for waterproofing pipelines. Background Technology

[0002] During pipeline waterproofing and anti-corrosion construction, adhesive is brushed onto the pipeline surface, and then reinforcing mesh is wrapped around it. After wrapping, the reinforcing mesh is manually pressed with a pressure roller to remove internal air bubbles and ensure full contact between the reinforcing mesh and the adhesive. After the adhesive cures, an integrated waterproof and anti-corrosion layer is formed. In the entire construction process, the manual operation of pressing the reinforcing mesh and adhesive is labor-intensive, resulting in a longer work cycle. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a rolling device for pipe waterproofing construction. By mechanically rolling and reinforcing the mesh, it not only improves work efficiency but also achieves a more uniform and stable compaction and curing effect.

[0004] The technical solution of this utility model is: a rolling device for pipeline waterproofing construction, including a base, on which two sets of rolling drive mechanisms are symmetrically arranged;

[0005] Each set of rolling drive mechanisms includes a telescopic bracket. The telescopic bracket has a rotating ring on the inner side of its top. A coaxially arranged gear ring is fixedly connected to the side of the rotating ring near the bracket. Two rollers that roll in contact with the inner circumference of the gear ring are rotatably connected to the bracket. The bracket also has a motor. A gear that meshes with the gear ring is connected to the motor. The gear and the two rollers are arranged in an equilateral triangle.

[0006] A crossbeam is connected between the two rotating rings of the rolling drive mechanism. A set of guide rods is slidably connected to the crossbeam along the radial direction of the rotating rings. One end of the set of guide rods is mounted with a roller shaft through a roller frame, and the other end is connected to a limit rod. A set of support springs is provided between the roller frame and the crossbeam.

[0007] Preferably, the base is a pallet cart.

[0008] Preferably, the swivel ring is detachably assembled from two semi-ring structures with lugs, and the gear ring is assembled from two semi-ring structures.

[0009] Preferably, the crossbeam is provided with an electrically operated telescopic rod for supporting the crossbeam after extension.

[0010] Preferably, the number of support springs is the same as the number of guide rods, and they are fitted onto the guide rods in a one-to-one correspondence.

[0011] Compared with the prior art, this utility model has the following advantages: This utility model can drive the crossbeam, roller frame and roller shaft to rotate along the outer circumference of the construction pipeline through the rolling drive mechanism, and use the roller shaft to roll the outer circumference of the construction pipeline, thereby rolling and reinforcing the mesh cloth in a mechanized way, reducing the labor intensity, shortening the construction cycle and improving the work efficiency. Moreover, after mechanized compaction and curing, the thickness of the cured layer is more uniform and stable. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0016] like Figure 1 and Figure 2 A rolling device for pipeline waterproofing construction includes a base 2, on which two sets of rolling drive mechanisms 1 are symmetrically arranged. The base 2 is a pallet truck for easy movement along the axis of the construction pipeline.

[0017] Each set of rolling drive mechanisms 1 includes a telescopic bracket 7. The inner side of the top of the telescopic bracket 7 is provided with a rotating ring 3. A coaxially arranged gear ring 4 is fixedly connected to the side of the rotating ring 3 near the bracket.

[0018] Two rollers 5 are rotatably connected to the bracket and roll in contact with the inner circumference of the gear ring 4. The bracket is also equipped with a motor 6, and a gear 8 that meshes with the gear ring 4 is connected to the motor 6. The gear 8 and the two rollers 5 are arranged in an equilateral triangle. The gear ring 4 is rotatably installed in the gap between the gear ring 8 and the two rollers 5.

[0019] A crossbeam 16 is connected between the rotating rings 3 of the two rolling drive mechanisms 1. Two guide rods 11 are slidably connected on the crossbeam 16 along the radial direction of the rotating rings 3. One end of the two guide rods 11 is mounted with a roller shaft 12 through a roller frame 13, and the other end is connected to a limit rod 9.

[0020] Two support springs 14 are provided between the roller frame 13 and the crossbeam 16, and the two support springs 14 are respectively mounted on the two guide rods 11.

[0021] Working principle: When in use, first adjust the height of the telescopic bracket 7 so that the rotating ring 3 is roughly coaxial with the construction pipeline. Then, put the rotating ring 3 on the outside of the construction pipeline, and the roller 12 is pressed on the reinforcing mesh cloth wrapped around the outer wall of the construction pipeline under the action of the support spring 14.

[0022] The starting motor 6 drives the gear 8 to rotate, and the gear 8 drives the rotating ring 3 to rotate through the gear ring 4. The rotating ring 3 drives the crossbeam 16, roller frame 13 and roller shaft 12 to rotate along the outer circumference of the construction pipeline. The roller shaft 12 is used to roll and press the outer circumference of the construction pipeline, thereby reinforcing the mesh cloth by mechanized rolling, reducing the labor intensity, shortening the construction cycle, improving the work efficiency, and after mechanized compaction and curing, the formed cured layer is more uniform and stable in thickness. Example 2

[0023] This embodiment is a further optimization based on the above embodiment, specifically:

[0024] like Figure 1 and Figure 2 This embodiment is applied to the construction of conveying pipelines that cannot be stopped and emptied. Because the pipeline is filled with conveying liquid during the production and conveying process, the pipeline cannot be cut or disassembled to fit the rotating ring 3. Therefore, the rotating ring 3 and the toothed ring 4 are designed as an assembly structure.

[0025] The swivel ring 3 is composed of two detachable semi-ring structures with lugs 15. The toothed ring 4 is also composed of two semi-ring structures. The toothed ring 4 and the swivel ring 3 are matched in their splicing positions. When in use, they are first disassembled into two semi-ring structures, which are then fastened to the outside of the construction pipe and assembled into a complete ring structure.

[0026] As a further optimization, the crossbeam 16 is equipped with an electric telescopic rod 10 for supporting the crossbeam 16 after extension.

[0027] The main application scenario of this solution is that after the roller pressing is completed on the current area of ​​the construction pipeline, it is necessary to move the pallet truck a certain distance to press the next part of the construction pipeline. At this time, the pallet truck is directly driven to move. Because the roller 12 is elastically pressed on the outer circumference of the construction pipeline, the friction is large, resulting in slow movement.

[0028] After the improvement, by controlling the extension of the electric telescopic rod 10, the supporting end of the electric telescopic rod 10 first contacts the crossbeam 16, and then supports the crossbeam 16 to move, thereby increasing the distance between the limiting rod 9 and the crossbeam 16, thereby compressing the supporting spring 14, and separating the roller 12 from the construction pipeline, which facilitates the movement of the pallet truck.

[0029] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
