[0021] Please refer to the following for details. Figures 1-5 A passive advanced pressurized water reactor ring hoisting and installation platform includes a platform body 1. The platform body 1 has an overall arc-shaped structure that can be adapted to the ring hoisting track 7. The platform body 1 includes 5 hangers 2 and 4 ramps 3. The hangers 2 are arranged at equal intervals. Each hanger 2 consists of a first support part 21 and a second support part 22 that are perpendicular to each other. The connection point between the first support part 21 and the second support part 22 is far from the center of the first support part 21. The ramps 3 are installed on the first support part 21 to provide workers with a safe and spacious construction platform.

[0022] Furthermore, the platform body 1 also includes four guardrails 4, which are installed on the first support part 21, providing safety for the staff.

[0023] Furthermore, the first support part 21 has a first mounting part 23 at the end away from the second support part 22, and the guardrail 4 is connected to the first mounting part 23.

[0024] In this embodiment, the first mounting part 23 is a large hollow square tube, which is welded to the first support part 21. The guardrail 4 is made of several small hollow square tubes welded together. The lower end of the guardrail 4 is inserted into the first mounting part 23 and has bolt holes, and is connected and fixed by bolt groups.

[0025] Furthermore, the platform body 1 also includes four reinforcing rods 5, which are installed on two adjacent brackets 2. One end of the reinforcing rod 5 is connected to one bracket 2, and the other end is connected to the other bracket 2. The reinforcing rods 5 serve to limit left and right movement and prevent the brackets 2 from swaying. The reinforcing rods 5 only bear axial tensile or compressive forces and do not bear bending moments or torques, and are not considered major load-bearing components.

[0026] Furthermore, a connecting rod 24 is provided at the upper end of the second support part 22, and a second mounting part 25 is provided on each side of the connecting rod 24, and the reinforcing rod 5 is connected to the second mounting part 25.

[0027] In this embodiment, the second mounting part 25 is an angle steel, which is welded to the connecting rod 24. The connecting rod 24 is welded to the second support part 22. The reinforcing rod 5 is a long angle steel of the same specification. Bolt holes are drilled on the second mounting part 25 and the reinforcing rod 5. The reinforcing rod 5 is connected and fixed to the second mounting part 25 with bolts.

[0028] Furthermore, the first support 21 has two web plates 26 located below the end near the second support 22. These web plates 26 engage with the vertical stiffeners of the ring track 7, limiting the left and right movement of the platform body 1. Below the connecting rod 24, two anti-slip plates 327 are located, engaging with the transverse stiffeners of the ring track 7, limiting the up and down movement of the platform body 1. The cooperation of the web plates 26 and the anti-slip plates 327 enhances the stability of the platform body 1.

[0029] Furthermore, the main body of the platform 1 also includes a ladder 6, which is installed on the bracket 2. The ladder 6 is a cage-type ladder. Workers can climb to the next floor via the ladder 6.

[0030] Furthermore, a third support 28 is provided on a bracket 2, the third support 28 is connected to the first support 21, and the third support 28 is welded and fixed to the first support 21. The ladder 6 is connected to the second support 22 and the third support 28, and the ladder 6 is welded and fixed to the second support 22 and the third support 28.

[0031] In this embodiment, multiple platform bodies 1 can be used together to connect into a whole, hooking onto the reinforcing plates of the ring-shaped track 7 to form a ring platform, thereby further preventing the platform bodies 1 from shaking and ensuring the stability of the platform bodies 1.

[0032] In other feasible embodiments, the outer side of the platform body 1 should be enclosed with a close-mesh safety net as needed. The close-mesh safety net should be firmly tied to the guardrail 4, and the color should meet the environmental effect requirements, with green being selected and flame-retardant.

[0033] like Figure 6As shown, the hanger 2 receives a weight of 330 N from itself and an external load of 2750 N. Therefore, F1y = G1 + G2 = 3180 N and F1x = F2 = (G1x280 + G2x1030) / 1945 = 1504 N, which meets the force requirements.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
