[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-3It can be seen that the present invention requires the use of lifting equipment for installation, the use of professional technicians, and installation in a safe environment (such as weather). During installation, the first fixing ring 1 and the second fixing ring 2 are first fixed to the designated position on the cooling tower by the expansion nail 3. The installation is strong enough, and the first fixing ring 1 and the second fixing ring 2 can be left intact after subsequent use. The first fixing ring 1 and the second fixing ring 2 can be designed as an integral circle, or a multi-section design corresponding to the platform 6. The spacing between the first fixing ring 1 and the second fixing ring 2 is 1m-1.5m. This distance can provide a good support effect for the subsequent installation of the platform 6, and the distance is not too far, which is convenient for personnel to operate. The platform 6 is then connected to the first fixing ring 1 by inserting the rod 5 into the sleeve 4 to form a first connection. At least four sections of platform 6 form a ring around the cooling tower, and the gap between two adjacent platforms 6 is less than 5cm, ensuring that the gap will not affect people walking on it. The ends of the multiple support rods 7 are connected to the second fixing ring 2 and the lower surface of the platform 6 near the outer ring via fixing plates 8, forming a second connection. Fixing plates 8 can be secured with screws 9. Handrails 10 are provided on the platform 6 via first connecting rods 11. Two adjacent handrails 10 are connected by clamps 15, typically secured with bolts, forming a third connection. This triple connection improves the stability of the platform 6, thereby enhancing safety.

[0023] Among them, a threaded rod 12 is provided at one end of the multiple first connecting rods 11 connected to the platform 6, and a through hole is opened at the position of the platform 6 corresponding to the threaded rod 12. The threaded rod 12 passes through the through hole to the bottom of the platform 6 and is screwed and connected through a nut 13. The screw connection is fixed for easy disassembly and installation.

[0024] A triangle design is formed between two adjacent first connecting rods 11 and the handrail 10, and between two adjacent first connecting rods 11 and the platform 6; a triangle design is formed between two adjacent support rods 7 and the platform 6, and between two adjacent support rods 7 and the second fixing ring 2; and multiple second connecting rods 14 are provided between the first fixing ring 1 and the second fixing ring 2. These second connecting rods 14 can be welded to form a triangle design between two adjacent second connecting rods 14 and the first fixing ring 1, and between two adjacent second connecting rods 14 and the second fixing ring 2. The triangle design provides stability, increasing the stability of the circular scaffolding.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
