[0013] Example 1

[0014] like Figure 1 and Figure 2 As shown, an anti-sway device for assembling a sleeve chimney includes rolling components. Multiple sets of rolling components are installed on the outer wall of the inner chimney 1 along its own axial direction. The rolling components include multiple bullseye bearings 2, which are evenly distributed around the circumference of the inner chimney 1. The universal balls 3 of the bullseye bearings 2 are used to contact the inner wall of the outer chimney 4 to provide support. The bullseye bearings 2 are installed on the inner chimney 1, and then the inner chimney 1 is hoisted for assembly. The inner chimney 1 is supported by the bullseye bearings 2 and installed into the outer chimney 4. The inner chimney 1 is moved by contacting the inner wall of the outer chimney 4 with the universal balls 3. This greatly reduces the friction between the inner chimney 1 and the outer chimney 4. One worker can easily push the inner chimney 1 into the outer chimney 4 without damaging the anti-corrosion, without increasing safety risks, reducing labor costs, and reducing assembly difficulty.

[0015] Example 2

[0016] Based on Example 1, such as Figure 1 and Figure 2 As shown, the rolling assembly also includes a welding base plate 5 and an adjusting shim 6. The welding base plate 5 is welded to the inner cylinder 1 of the chimney, and the adjusting shim 6 is fixed to the welding base plate 5. The end of the bullseye bearing 2 away from the universal ball bearing 3 is detachably connected to the adjusting shim 6. Several adjusting shims 6 are arranged between the welding base plate 5 and the bullseye bearing 2. By changing the number of adjusting shims 6, the installation height of the bullseye bearing 2 can be adjusted to adapt to the assembly dimensions between the inner cylinder 1 and the outer cylinder 4 of the chimney, so that the universal ball bearing 3 of the bullseye bearing 2 contacts the outer cylinder 4 of the chimney to provide support, and complete the rapid assembly of the inner cylinder 1 of the chimney.

[0017] Example 3

[0018] Based on Example 2, such as Figure 2As shown, the adjusting shim 6 has a through hole 7, and the welding base plate 5 has a threaded hole 8 corresponding to the through hole 7. The base plate of the bullseye bearing 2 has a mounting through hole 10. The long bolt 9 passes through the mounting through hole 10 and the through hole 7 in sequence and is threaded into the threaded hole 8. Both the adjusting shim 6 and the bullseye bearing 2 can be detached for easy adjustment of the number of adjusting shims 6 installed. Specifically, the bullseye bearing 2 is removed by removing the long bolt 9, and then the corresponding number of adjusting shims 6 is configured according to the design dimensions. Then, the tail of the long bolt 9 is passed through the mounting through hole 10 and the through hole 7 in sequence, and finally the bolt is fitted into the threaded hole 8 to complete the assembly of the rolling assembly. It can adapt to the assembly of chimneys of various sizes and has a wider range of applications.
