[0036] See also Figures 1 to 3 In one embodiment of the present invention, the unloading platform for the construction of the nuclear island 100 is formed with a floor 110 and a ceiling layer 120 located above the floor 110. The unloading platform includes:

[0037] The platform structure 200 has a connecting end 210 and a cantilevered end 220 at either end. The connecting end 210 is detachably connected to the floor 110, and the cantilevered end 220 cantilevers outward and extends away from the nuclear island 100.

[0038] an anti-overturning assembly 300, one end of which is detachably connected to the ceiling, and the other end of which is connected to the cantilever end 220; and

[0039] The detection mechanism 400 is installed on the anti-overturning component 300 to detect the anti-overturning load data.

[0040] It should be particularly and clearly stated that in this embodiment, during the specific implementation, the unloading platform exemplified in this embodiment is a prefabricated part. During the specific implementation, the prefabricated part can be prefabricated and assembled on the ground in the construction area of ​​the nuclear island 100. After the prefabricated assembly is completed, the completed prefabricated part will be hoisted to the construction area to complete the installation.

[0041] In this embodiment, by providing a platform structure 200, an anti-overturning assembly 300, and a detection mechanism 400, when in use, the platform structure 200 is cantilevered and installed on the floor 110 of the nuclear island 100, and the anti-overturning assembly 300 is used to detachably connect the cantilevered end 220 of the platform structure 200 to the ceiling layer 120 of the nuclear island 100. At the same time, the detection mechanism 400 is installed on the anti-overturning assembly 300, and the detection mechanism 400 is used to perform real-time detection of the load data borne by the anti-overturning assembly 300. This allows the utility model to use the provided nuclear island 100 platform to provide a construction channel for the construction of the nuclear island 100, eliminating the need to set up scaffolding during the main construction of the nuclear island 100, thereby reducing the difficulty of construction. At the same time, in actual use, since the nuclear island 100 platform can be provided as a prefabricated structure, the utility model can directly hoist and install the nuclear island 100 platform on the floor 110 structure of the nuclear island 100 when in use, reducing the consumption of manpower and material resources and improving construction efficiency.

[0042] In some embodiments, the anti-overturning assembly 300 includes:

[0043] A first mounting ear 310 , the first mounting ear 310 being mounted on the ceiling layer 120 ; and

[0047] It should be specifically and clearly stated that in this embodiment, the connection between the illustrated first mounting ear 310 and the ceiling floor can be achieved by pre-embedding the first mounting ear 310 in the ceiling floor, or by drilling holes in the ceiling floor and then securing the first mounting ear 310 to the floor with bolts. Of course, to minimize damage to the floor, the preferred method for pre-embedding the first mounting ear 310 is in this embodiment. It should be clarified that when pre-embedding the first mounting ear 310, the first mounting ear 310 should be connected to a load-bearing structure, such as structural reinforcement, in the ceiling floor to enhance the structural stability of the first mounting ear 310. It should also be noted that in this embodiment, the illustrated connecting rope 320 should be a steel rope 235.

At the same time, due to the increase in the number of first mounting ears 310 and connecting ropes 320, the platform structure 200 can also withstand a larger load.

[0050] In some specific embodiments, there are two connecting ropes 320 connected to the same first mounting ear 310, and a detection mechanism 400 is installed on each connecting rope 320.

[0051] In this embodiment, two connecting ropes 320 are provided on the same first mounting ear 310 , and the two connecting ropes 320 are connected at different positions, so that the present invention has a stronger load capacity when in use.

[0052] In some preferred embodiments, the anti-overturning assembly 300 further includes a connecting plate 330 , the first mounting ear 310 is mounted on the connecting plate 330 , and the first mounting ear 310 is pre-buried in the ceiling layer 120 through the connecting plate 330 .

[0053] In this embodiment, the connection plate 330 is provided, so that the present invention has stronger connection stability when in use.

[0054] In one embodiment, the detection mechanism 400 includes:

[0055] a strain measurement sensor 410 , which is mounted on the connecting rope 320 to measure the instantaneous load of the connecting rope 320 ; and

[0056] The alarm terminal 420 is in communication with the deformation measurement sensor 410 , and the alarm terminal 420 can sound an alarm when the platform structure 200 is overloaded.

[0057] In this embodiment, by setting up a deformation measurement sensor 410 and an alarm terminal 420, the utility model can use the set deformation measurement sensor 410 to instantly measure the real-time deformation data of the connecting rope 320 when in use, thereby realizing the function of real-time detection of the instantaneous load of the connecting rope 320.

[0058] It should be particularly and clearly stated that, in this embodiment, the exemplary deformation measurement sensor 410 and the alarm terminal 420 both use existing technologies, and no improvement or design is made thereto in this embodiment. Therefore, they will not be described in detail here.

[0059] In one embodiment, the platform structure 200 includes:

[0060] A table top 230, with two ends of the table top 230 forming a connecting end 210 and a cantilevered end 220, respectively. The connecting end 210 is detachably mounted on the floor 110 through a plurality of buckles; and

[0061] The fence 240 is installed on the table 230 , and the fence 240 is arranged around the position from the cantilever end 220 to the connecting end 210 .

[0062] In this embodiment, by providing the tabletop 230 and the fence 240 , the utility model can ensure the safety and stability of the overall structure when in use.

[0063] In some exemplary embodiments, the table 230 includes:

[0064] A main frame 231, wherein the main frame 231 has a connecting end 210 and a cantilevered end 220 at both ends along its length direction; and

[0065] The cover plate 232 is disposed on the cantilevered end 220 and extends from the cantilevered end 220 to the connecting end 210 .

[0066] A plurality of second mounting ears 233 are respectively provided on both sides of the main frame 231 along the length direction. The second mounting ears 233 are spaced apart along the length direction of the main frame 231 . The connecting rope 320 can be connected to any second mounting ear 233 .

[0067] In this embodiment, by providing the second mounting ear 233 , the second mounting ear 233 can be disassembled and assembled during use, thereby improving the stability of the overall structure.

[0068] Of course, in some feasible embodiments, in order to avoid the hidden danger of the connecting rope 320 breaking when the unloading platform is overloaded, the platform structure 200 of the example of the present invention also includes a sliding base 234. The sliding base 234 of the example can be slidably installed on the main frame 231, and the cover 232 and the fence 240 of the example can be set on the sliding base 234. The sliding base 234 is used to carry materials. At the same time, the sliding base 234 should be connected to the winch 236 installed on the floor 110 where the fixed main frame 231 is located through a steel rope 235. When the load on the unloading platform is overloaded and there is no person standing on the platform, the winch 236 can be operated to pull the sliding base 234 into the floor 110, so that the utility model reduces the hidden danger of safety accidents caused by the breaking of the connecting rope 320 due to overloading.
