[0045] According to an embodiment of the present application, with reference to Figure 1 and Figure 2As shown in the figure, the present application provides an overhaul platform, including: a frame structure 1 and an operation platform 2. Among them, X, Y, and Z respectively represent the length direction, width direction, and height direction of the frame structure 1. The frame structure 1 includes a first side frame 11, a second side frame 12, and a folding frame 13. The first side frame 11 and the second side frame 12 are arranged at intervals along the length direction X of the frame structure 1, located on the left and right sides of the frame structure 1 along the length direction X. The opposite sides of the folding frame 13 are respectively connected to the first side frame 11 and the second side frame 12, and the folding frame 13 can be folded in the length direction X of the frame structure 1 to adjust the length of the frame structure 1; the operation platform 2 is detachably connected to the same side end of the first side frame 11 and the second side frame 12. In this example, this side end can be the top end.

[0046] During installation, the first side frame 11 and the second side frame 12 are arranged at intervals left and right, then the folding frame 13 is connected between the first side frame 11 and the second side frame 12, and then the folding frame 13 is adjusted to make the overhaul platform adapt to the working site. Finally, the operation platform 2 with a suitable size is connected to the tops of the first side frame 11 and the second side frame 12 to complete the assembly.

[0047] In this embodiment of the present application, the overhaul platform is divided into multiple modules such as the first side frame 11, the second side frame 12, the folding frame 13, and the operation platform 2. This modular design is conducive to rapid on-site assembly and disassembly, improves work efficiency, and reduces potential safety hazards caused by complex construction.

[0048] Compared with the traditional scaffolding that requires one-by-one installation of numerous components, the modular and foldable characteristics of the overhaul platform of the present application significantly simplify the installation process, reduce the construction time, and enable the overhaul work to be carried out more flexibly and efficiently. Moreover, it can be easily disassembled and stored when not in use, occupying little space and being convenient for storage and transportation.

[0049] In addition, the folding frame 13 can be folded in the length direction, which means that the overhaul platform can be adjusted according to the size of the actual working space, greatly enhancing its adaptability. This is particularly important for the environment with variable space and strict restrictions in nuclear power plants, and can ensure the smooth progress of overhaul work under various conditions.

[0050] According to an embodiment of the present application, with reference to Figure 2As shown in the figure, the first side frame 11 includes: a first vertical rod 111, a second vertical rod 112, and a first cross rod 113. The first vertical rod 111 and the second vertical rod 112 are located on the front and rear sides of the frame structure 1 along the width direction Y. A folding frame 13 is connected between the second side frame 12 and the first vertical rod 111 and / or the second vertical rod 112; the first cross rod 113 is connected between the first vertical rod 111 and the second vertical rod 112. The working platform 2 has a first side 21, and the first side 21 of the working platform 2 is detachably connected to the first cross rod 113. In this example, the first side 21 of the working platform 2 is the left side.

[0051] Moreover, the second side frame 12 includes: a third vertical rod 121, a fourth vertical rod 122, and a second cross rod 123. The third vertical rod 121 and the fourth vertical rod 122 are located on the front and rear sides of the frame structure 1 along the width direction Y, and the third vertical rod 121 is aligned with the first vertical rod 111, and the fourth vertical rod 122 is aligned with the second vertical rod 112. A folding frame 13 is connected between the third vertical rod 121 and the first vertical rod 111 and / or between the fourth vertical rod 122 and the second vertical rod 112; the second cross rod 123 is connected between the third vertical rod 121 and the fourth vertical rod 122, and is arranged opposite to the first cross rod 113 to achieve alignment. The working platform 2 has a second side 22, and the second side 22 of the working platform 2 is detachably connected to the second cross rod 123. In this example, the second side 22 of the working platform 2 is the right side.

[0052] In addition, the first side frame 11 further includes a third cross rod 114, and the third cross rod 114 is connected between the first vertical rod 111 and the second vertical rod 112, and is arranged at an upper and lower interval with the first cross rod 113 along the height direction Z of the frame structure 1; and / or, the second side frame 12 further includes a fourth cross rod 124, and the fourth cross rod 124 is connected between the third vertical rod 121 and the fourth vertical rod 122, and is arranged at an upper and lower interval with the second cross rod 123 along the height direction Z of the frame structure 1.

[0053] In this embodiment of the present application, the four vertical rods of the frame structure 1 are the main load-bearing rods, mainly playing a supporting role. They bear the loads transmitted by the four cross rods and are important load-bearing components. Their stability determines the bearing capacity and safety of the frame structure 1. For example, the four vertical rods of the maintenance platform can be made of aluminum alloy pipes with a diameter of 60 mm to ensure the overall stability and safety of the frame structure 1. Moreover, the aluminum alloy material not only has good corrosion resistance and is suitable for the chemical corrosion environment in the nuclear power plant, but also has a low density and high strength, can effectively support the weight of the maintenance platform and the load of the operators and equipment, and at the same time keep the overall structure lightweight, which is convenient for handling and erection.

[0054] By ensuring the alignment between the third vertical rod 121 and the first vertical rod 111, and between the fourth vertical rod 122 and the second vertical rod 112, not only the aesthetic appearance of the maintenance platform is improved, but more importantly, the smooth operation of the folding mechanism is guaranteed. When unfolding or folding, each component can be accurately docked, reducing misalignment or jamming phenomena, and ensuring the convenience and safety of the operation.

[0055] The four crossbars and vertical rods of the frame structure 1 are welded into side frames, which can effectively transfer and disperse the acting force of the load on the maintenance platform. The crossbars not only serve as components connecting the vertical rods, playing a key role in fixing the shape of the frame structure 1, but also are firmly combined with the vertical rods by welding, enhancing the rigidity and stability of the overall frame. The layout of the four crossbars ensures that both sides of the working platform 2 can be evenly supported. At the same time, their design can adapt to the needs of different maintenance operations. By reasonably distributing the load, the safety risks caused by local overload are effectively avoided. In addition, the crossbars can also adjust the shape and size of the structure to make it more in line with the design requirements of special maintenance platforms.

[0056] Both sides of the working platform 2 are detachably connected to the first crossbar 113 and the second crossbar 123 respectively. Such a design facilitates adjusting the position of the working platform 2 according to actual needs, providing flexibility for maintenance operations. At the same time, it also simplifies the maintenance and replacement process of the working platform 2. When the working platform 2 itself needs to be inspected or replaced, it can be quickly completed without affecting the structural stability of the entire frame.

[0057] According to an embodiment of the present application, the first vertical rod 111, the second vertical rod 112, the third vertical rod 121 and the fourth vertical rod 122 can all be telescoped along the height direction Z of the frame structure 1, and / or, the first crossbar 113 and the second crossbar 123 can be telescoped along the width direction Y of the frame structure 1.

[0058] Moreover, when designing the third crossbar 114 and the fourth crossbar 124, they can also be telescoped synchronously with the first crossbar 113 and the second crossbar 123.

[0059] Taking the telescopic structure of the first vertical rod 111 as an example, the first vertical rod 111 includes: a first rod body and a second rod body. A slideway is provided inside the first rod body, and the top end of the second rod body can telescopically slide in the slideway of the first rod body. And a plurality of first locking holes are arranged at intervals along the length direction on the first rod body. Correspondingly, a plurality of second locking holes are arranged at intervals along the length direction on the second rod body. After adjusting the height of the first vertical rod 111, the first locking hole and the second locking hole can be connected by fasteners such as bolts to achieve locking.

[0060] The telescopic structures of other vertical rods and crossbars are similar to this, and will not be elaborated here. Of course, the vertical rods and crossbars can also adopt other commonly used telescopic rod structures.

[0061] In this embodiment of the present application, by introducing the telescopic function of the vertical poles and horizontal bars, the maintenance platform can more precisely match various complex and special working environments. Specifically:

[0062] Telescopic design of the vertical poles: These four vertical poles can telescope along the height direction Z of the frame structure 1, which means that the maintenance platform can be adjusted according to the actual working height without affecting its stability. This design is particularly useful for the maintenance of regulating valves at different positions and heights in nuclear power plants. For example, some valves are located at higher positions, and it is difficult for traditional fixed-height platforms to reach the ideal working position, while the telescopic vertical poles can easily adapt, improving the accessibility and efficiency of maintenance.

[0063] Telescopic design of the horizontal bars: The telescopic ability of the horizontal bars in the width direction further expands the applicable range of the platform. It allows the platform to adjust its size in the horizontal direction and is suitable for working areas with different widths. This is particularly crucial for situations where the space is narrow or a large maintenance area needs to be covered. By simple adjustment, it can ensure that the working platform 2 meets the working area, improving the safety and efficiency of the operation.

[0064] Therefore, through the integration of the above telescopic functions in the present application, the maintenance platform can adapt to working environments of any size. Whether it is a narrow passage or a maintenance area that needs to cover a large area, the best match can be achieved through simple adjustment.

[0065] Moreover, there is no need to build multiple platforms of different sizes or carry out complex on-site modifications. One platform can meet various operation requirements, shortening the preparation time and improving the smoothness and efficiency of the overall maintenance process.

[0066] According to an embodiment of the present application, with reference to Figure 1 、 Figure 2 and Figure 4 shown, the third cross bar 114 and the fourth cross bar 124 are oppositely arranged to achieve alignment. The frame structure 1 further includes a reinforcing bar 14, and both ends of the reinforcing bar 14 are respectively clamped with the third cross bar 114 and the fourth cross bar 124.

[0067] Specifically, both ends of the reinforcing bar 14 are respectively provided with buckles 141, and the buckles 141 are formed with clamping grooves 142. During installation, after adjusting the folding frame 13, the reinforcing bar 14 with a suitable size is placed on the third cross bar 114 and the fourth cross bar 124, and the clamping grooves 142 of the buckles 141 at both ends of the reinforcing bar 14 are clamped with the third cross bar 114 and the fourth cross bar 124.

[0068] In this embodiment of the present application, the third cross bar 114 and the fourth cross bar 124 are oppositely arranged and aligned. Such a layout design adds additional support points in the horizontal direction of the frame structure 1, which helps to balance the load distribution on the working platform 2.

[0069] Both ends of the reinforcing rod 14 are clamped with the third cross bar 114 and the fourth cross bar 124 respectively. This design not only simplifies the reinforcement process, but also ensures the firm and reliable connection between the reinforcing rod 14 and the cross bar. The function of the reinforcing rod 14 can be understood as similar to the cable in a bridge. Through its own tension, it provides additional stability for the entire frame structure 1. Especially when the maintenance platform is unfolded and bears heavy objects, it can significantly reduce the bending or shaking of the frame and improve the safety during operation.

[0070] Through the combined design of the reinforcing rod 14 with the third cross bar 114 and the fourth cross bar 124, the original two-side frame structures are effectively connected and strengthened in the middle, forming a more solid overall frame. This structural integration not only improves the wind resistance and seismic performance of the maintenance platform under various working conditions, but also ensures the stability of the platform structure in the folded and unfolded states, avoiding potential safety hazards caused by structural looseness.

[0071] According to an embodiment of the present application, the reinforcing rod 14 can be telescoped along the length direction X of the frame structure 1. The telescopic structure of the reinforcing rod 14 can be similar to the above-mentioned first vertical rod 111 or other common telescopic rod structures, which will not be elaborated here.

[0072] With such a design, the reinforcing rod 14 can adjust its length synchronously with the folding of the folding frame 13, ensuring that during the process of changing the overall size of the maintenance platform, the reinforcing rod 14 always remains adapted to the frame structure 1. This design avoids the reinforcing rod 14 becoming a limiting factor when adjusting the platform size, making the platform size adjustment process smoother, and at the same time ensuring the overall stability of the platform structure at any set size.

[0073] According to an embodiment of the present application, referring to Figure 2 As shown, at least one group among the two ends of the first cross bar 113 between the first vertical rod 111 and the second vertical rod 112, the two ends of the third cross bar 114 between the first vertical rod 111 and the second vertical rod 112, the two ends of the second cross bar 123 between the third vertical rod 121 and the fourth vertical rod 122, and the two ends of the fourth cross bar 124 between the third vertical rod 121 and the fourth vertical rod 122 is provided with an inclined support rod 15.

[0074] In this example, the two ends of the first cross bar 113 between the first vertical rod 111 and the second vertical rod 112, the two ends of the third cross bar 114 between the first vertical rod 111 and the second vertical rod 112, the two ends of the second cross bar 123 between the third vertical rod 121 and the fourth vertical rod 122, and the two ends of the fourth cross bar 124 between the third vertical rod 121 and the fourth vertical rod 122 are all provided with inclined support rods 15.

[0075] In this embodiment of the present application, by adding diagonal support rods 15 at key positions of the frame structure 1, the overall structural stability and safety of the maintenance platform are further enhanced. Specifically, the introduction of the diagonal support rods 15 brings the following effects:

[0076] 1. Force balance and pressure dispersion

[0077] The diagonal support rods 15 form a triangular structure with the corresponding crossbars and vertical poles, which can effectively balance the stress states among various components. Especially under heavy loads or non-uniform loads, the diagonal support rods 15 can disperse the pressure, reduce the stress concentration of a single component, and thus protect the entire structure from excessive local stress damage.

[0078] 2. Effective connection between components and load transfer

[0079] The diagonal support rods 15 are not only a mechanical support but also a bridge connecting the crossbars and vertical poles. It ensures the integrity of the platform structure as a whole, enables the load to be effectively transferred and dispersed along multiple paths, avoids the risk of single-point failure, and improves the overall reliability of the structure.

[0080] 3. Controlling structural deformation and improving stiffness

[0081] The high stiffness characteristics of the diagonal support rods 15 can effectively restrain the lateral deformation of the frame. Especially when the platform is expanded to the maximum size or under extreme conditions, it can significantly inhibit the twisting or bending of the frame, and maintain the flatness of the platform and the geometric stability of the structure.

[0082] 4. Improvement of seismic performance

[0083] Under the action of earthquakes or other dynamic loads, the diagonal support rods 15 can significantly improve the seismic capacity of the entire structure. They absorb and dissipate energy, reduce the vibration response of the structure, enable the platform to maintain good stability during earthquakes, reduce potential damage, and ensure the safety of personnel.

[0084] According to an embodiment of the present application, referring to Figure 2 and Figure 3 as shown, the folding frame 13 includes: a first connecting rod 131 and a second connecting rod 132. The first end of the first connecting rod 131 is hinged to the first side frame 11; the first end of the second connecting rod 132 is hinged to the second end of the first connecting rod 131, the second end of the second connecting rod 132 is hinged to the second side frame 12, and the first end of the second connecting rod 132 is fixedly connected to the second end of the first connecting rod 131 through a fastener 133.

[0085] In this embodiment of the present application, this double-link hinge structure is the key to realizing the folding of the platform. It allows the platform to perform flexible opening and closing actions, thus adapting to different space requirements. Moreover, the first end of the second link 132 is fixedly connected to the second end of the first link 131 through fasteners 133 such as bolts and pins. This is not only part of the hinge structure but also ensures the stability and safety when the platform is unfolded for use.

[0086] In one example, as Figure 1 and Figure 2 shown, two folding frames 13 arranged horizontally one above the other are respectively connected between the first vertical rod 111 and the third vertical rod 121 on the front side of the frame structure 1. Multiple diagonal support rods 15 can be connected at intervals between the two folding frames 13, and the reinforcing rod 14 is located at the rear side of the frame structure 1. Designed in this way, the stability of the frame structure 1 can be further improved.

[0087] U-shaped ear seats 16 are provided on both the first vertical rod 111 and the third vertical rod 121. The first end of the first link 131 and the second end of the second link 132 of the folding frame 13 are respectively hinged within the U-shaped ear seats 16 through connecting parts such as screws and pin shafts, so as to facilitate the unfolding and folding of the folding frame 13.

[0088] According to an embodiment of the present application, referring to Figure 2 shown, the first vertical rod 111, the second vertical rod 112, the third vertical rod 121, and the fourth vertical rod 122 are all hollow tubes, and a plug plate 17 is provided at the top of the hollow tube, and an anti-slip pad 18 is provided at the bottom of the hollow tube.

[0089] In this embodiment of the present application, by designing the vertical rods as hollow tubes, the weight of the overall structure can be reduced, which is convenient for handling and assembly; the plug plate 17 is used to block the four hollow vertical rods to prevent foreign objects from entering the vertical rods; the anti-slip pad 18 is a kind of pad for preventing sliding, and its main function is to increase the friction between the object and the ground to prevent movement. The four anti-slip pads 18 are installed at the bottoms of the four vertical rods, which can enhance the stability of the maintenance platform.

[0090] According to an embodiment of the present application, referring to Figure 1 and Figure 2 shown, the frame structure 1 further includes a ladder 19, and the ladder 19 is connected to the first side frame 11 and / or the second side frame 12.

[0091] Specifically, to facilitate the maintenance personnel to get on and off the working platform 2, by designing the ladder 19, the maintenance personnel can climb onto the working platform 2 safely and easily, which is convenient and fast, and effectively improves the work efficiency.

[0092] According to an embodiment of the present application, referring to Figure 1 and Figure 5As shown, the working platform 2 includes: a platform frame 23 and grab fasteners 24. A number of grab fasteners 24 are provided on both sides of the platform frame 23.

[0093] Among them, the platform frame 23 can adopt a non-slip plate design to provide anti-slip performance and prevent maintenance personnel from sliding or falling when working on the platform frame 23. This design mainly considers the stability of placing maintenance tools and the safety of maintenance personnel.

[0094] The four corners of the platform frame 23 adopt a common hook-shaped grab fastener 24 design. The hook-shaped grab fastener 24 can be firmly fixed on two cross bars of the frame structure 1, connecting the working platform 2 and the frame structure 1 into a stable whole.

[0095] According to an embodiment of the present application, the platform frame 23 of the working platform 2 can be telescoped along the length direction X of the frame structure 1.

[0096] With such a design, the working platform 2 can adjust its length synchronously with the folding of the folding frame 13, ensuring that the working platform 2 always remains adapted to the frame structure 1 during the process of changing the overall size of the maintenance platform.

[0097] For example, the platform frame 23 includes a first frame and a second frame that are slidably connected to each other, and a plurality of fastening holes are provided on both the first frame and the second frame corresponding to each other along the length direction. When adjusting the folding frame 13, the first frame and the second frame slide relative to each other. After the adjustment is completed, the fastening holes are locked by fasteners such as screws to complete the fixation.
