Description

Technical Field

[0001] This invention relates to the field of nuclear power equipment technology, and more specifically, to a support for transporting and rotating nuclear power plant guide columns. Background Technology

[0002] Guide columns are crucial components of nuclear power reactor pressure vessels. Long guide columns are approximately 9 meters in length, while short guide columns are approximately 4 meters. In current technologies, guide columns are transported by connecting them to bolts at both ends of the column, securing them within a transport frame in groups of three. During lifting and tilting, the bolts must be removed from each end individually, and one end of the guide column must be lifted off the ground at a certain height using slings before connecting the lifting lugs and finally lifting it. This method of securing and lifting requires multiple bolt removals and reassemblies, making it cumbersome. Furthermore, when one end of the guide column is tilted to a certain angle during lifting, uncontrollable swaying under gravity can easily damage the surface of the guide column and injure operators, posing a significant operational safety hazard.

Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1 to 5 As shown, the support for transporting and flipping the nuclear power plant guide column 8 in this embodiment of the invention includes a base plate 1, a support frame 2, a fixing component 3, and a flipping component 4. The length direction of the base plate 1 is defined as the left-right direction, the width direction of the base plate 1 is defined as the front-back direction, and the thickness direction of the base plate 1 is defined as the up-down direction.

[0027] The top surface of the base plate 1 is provided with a first frame 5. For example, the first frame 5 includes two first rods and a second rod. The two first rods are spaced apart in the front-back direction and extend in the left-right direction. The second rod is fixed above the two first rods and located on the right side.

[0028] Two second frames 6 are spaced apart on the left side of the first frame 5 in the front-to-back direction. The support frame 2 is rotatably mounted on the two second frames 6 about an axis extending in the front-to-back direction. For example, the second frame 6 is a plate-shaped structure. A first lug is provided on the top of the second frame 6. The support frame 2 is rotated and fixedly engaged with the second frame 6 through the two first lugs.

[0029] The fixing component 3 is located above the support frame 2. The fixing component 3 is used to fix the guide column 8 to the support frame 2. The flipping component 4 is located on the base plate 1. The flipping component 4 is rotatably connected to the support frame 2 and is used to drive the support frame 2 to rotate. The support frame 2 has a transportation position and a hoisting position. In the transportation position, the support frame 2 is supported on the first frame 5. In the hoisting position, the support frame 2 is set vertically or inclined to form an angle with the base plate 1, and the angle is not greater than 90°.

[0030] The support frame for transporting and flipping the nuclear power plant guide column 8 according to this embodiment of the invention, in use, drives the support frame 2 to move to the transport position through the flipping component 4. In the transport position, the support frame 2 is set horizontally, and the bottom of the support frame 2 abuts against the first frame 5 to ensure the stability and reliability of the support frame 2 in supporting the guide column 8 and during the transport process. The guide column 8 is placed on the support frame 2 and fixed by the fixing component 3 on the support frame 2, which further improves the stability and safety of the guide column 8 during the transport process. When the support frame is transported to the installation position of the guide column 8, the support plate can be adjusted to the hoisting position through the flipping component 4, so that the guide column 8 is vertical, which facilitates the hoisting operation. After the guide column 8 is connected to the hoisting component, the fixing component 3 is released from fixing the guide column 8.

[0031] The support for transporting and flipping the nuclear power plant guide column 8 in this embodiment of the invention has a transport position and a hoisting position on the support plate by rotating the support frame 2 relative to the second frame 6, which facilitates the transport and flipping of the guide column 8. By setting the flipping component 4, it is convenient to perform the flipping operation when installing the guide column 8, which saves time and effort and is easy to operate. Furthermore, the fixing component 3 improves the stability and safety of the guide column 8 during transport and flipping, making it safe and reliable.

[0032] Optionally, in the hoisting position, the angle between the support frame 2 and the base plate 1 is 60°, 70°, 80°, or 90°. Preferably, the angle is 90°. When the guide column 8 is vertically set in the hoisting position, it facilitates hoisting and reduces swaying during hoisting, further improving the safety of the operation.

[0033] In some embodiments, such as Figures 1 to 4 As shown, the bottom surface of the support frame 2 is provided with a first rotating shaft 21 and a second rotating shaft 22. The support frame 2 is rotatably connected to the second frame 6 through the first rotating shaft 21, and the second rotating shaft 22 is connected to the flipping assembly 4. The flipping assembly 4 is used to drive the support frame 2 to rotate through the second rotating shaft 22.

[0034] In this embodiment, the first rotating shaft 21 is used as the rotating shaft of the support frame 2. The second rotating shaft 22 is driven to rotate around the axis of the first rotating shaft 21 by the flipping component 4. The operation is convenient, the driving process is smooth, and the stability is strong.

[0035] Specifically, the first rotating shaft 21 is rotatably mounted on two first lugs, and a second lug is provided below the support frame 2. The second lug is located to the right of the first lugs, and the second rotating shaft 22 is rotatably mounted on the second lug. Optionally, multiple second lugs are provided at intervals in the front-back direction on the support frame 2.

[0036] In some embodiments, such as Figure 1 and Figure 3 As shown, the flipping assembly 4 includes a drive motor 41, a first drive rod 42, and a second drive rod 43. The drive motor 41 is fixedly mounted on the base plate 1, the first drive rod 42 is fixedly mounted on the output shaft of the drive motor 41, and the second drive rod 43 is rotatably mounted on the first drive rod 42, with the other end of the second drive rod 43 rotatably connected to the second rotating shaft 22.

[0037] In this embodiment, the first drive rod 42 is driven to rotate by the drive motor 41, and the first drive rod 42 drives the second drive rod 43 to rotate. The second drive rod 43 is rotatably connected to the second rotating shaft 22, thereby driving the second rotating shaft 22 and the support frame 2 to rotate around the first rotating shaft 21. The operation is convenient, stable, safe and reliable.

[0038] Optionally, the drive motor 41 is a dual-axis output motor, that is, the drive shaft of the drive motor 41 passes through both sides of the housing, and the two ends of the drive shaft are respectively provided with a first drive rod 42, and a second drive rod 43 with the other end rotatably connected to the two first drive rods 42.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the base plate 1 is provided with mounting holes 11, which are used to connect with the transport platform or support platform. By setting the mounting holes 11, it is easy to fix the base plate 1, thereby moving and fixing the entire bracket to adapt to different working environments and with strong stability.

[0040] Optionally, mounting holes 11 are provided in multiples, such as two, three, or four.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple support columns 12 are provided between the first frame 5 and the base plate 1, and there is a set distance between the first frame 5 and the base plate 1.

[0042] In this embodiment, by setting multiple support columns 12 on the base plate 1, a set distance is created between the first frame 5 and the base plate 1, which facilitates the installation of the flipping component 4. When the support frame 2 is in the transport position, a receiving cavity for the flipping component 4 can be formed between the support frame 2, the first frame 5 and the base plate 1, which facilitates overall storage and simplifies the overall structure of the bracket.

[0043] In some embodiments, such as Figure 1 and Figure 5 As shown, the fixing component 3 includes a fixing half-ring 31, one end of which is detachably connected to the support frame 2, and the other end of which is detachably connected to or rotatably engaged with the support frame 2.

[0044] In this embodiment, by setting a fixed half-ring 31, it is easy to fix the guide column 8 on the support frame 2, thereby improving the safety and stability during transportation and flipping.

[0045] Specifically, during installation, both ends of the fixed half-ring 31 are detachably connected to the support frame 2, or one end of the fixed half-ring 31 is detachably connected to the support frame 2, and the other end is rotatably engaged with the support frame 2.

[0046] When the end of the fixed half ring 31 is detachably connected to the support frame 2, a through hole can be provided on the support frame 2, and a connecting plate segment can be provided at the end of the fixed half ring 31. By inserting fixing bolts through the connecting plate segment and the through hole, the support frame 2 and the fixed half ring 31 can be connected together.

[0047] When the end of the fixed half-ring 31 is rotatably connected to the support frame 2, connecting lugs can be provided at the ends of the support and fixed plate sections, and connecting shafts can be inserted at the two connecting lug positions to achieve rotational engagement between the end of the fixed half-ring 31 and the support frame 2.

[0048] In some embodiments, such as Figure 1 and Figure 5 As shown, the fixing component 3 includes an elastic buffer half-ring 32, which is disposed inside the fixing half-ring 31. The two ends of the buffer half-ring 32 are rotatably connected to the fixing half-ring 31, and a buffer cavity is restricted between the buffer half-ring 32 and the fixing half-ring 31.

[0049] In this embodiment, by setting a buffer semi-ring 32, the fixed semi-ring 31 increases the fixing effect on the guide post 8, thereby improving the safety and stability of the bracket during transportation and flipping.

[0050] In some embodiments, such as Figure 1 and Figure 5 As shown, the fixing component 3 includes an elastic element 33, which is disposed in the buffer cavity and fixedly connected to at least one of the buffer half ring 32 and the fixed half ring 31. The elastic element 33 is used to drive the buffer half ring 32 to move away from the fixed half ring 31 in the radial direction of the fixed half ring 31 when the buffer half ring 32 is in contact with the guide post 8.

[0051] In this embodiment, by setting an elastic element 33, when the guide post 8 is fixed, the elastic element 33 can support the buffer half-ring 32 and provide buffering when the plate segment of the buffer half-ring 32 undergoes elastic deformation towards the fixed plate segment. This provides a reverse force to the buffer half-ring 32, further improving the fixing effect of the fixed half-ring 31 and the buffer half-ring 32 on the guide post 8, thereby improving the safety and stability of the bracket during transportation and flipping.

[0052] Specifically, the elastic element 33 is a top support spring. The two ends of the top support spring are fixedly connected to the buffer half ring 32 and the fixed half ring 31, respectively. When the buffer half ring 32 undergoes elastic deformation, the top support spring is compressed, providing a reverse support force for the buffer half ring 32, thereby improving the fixing effect on the guide post 8.

[0053] In some embodiments, the top surface of the support frame 2 is provided with a limiting part 23, which is used to support the column and partially fits the column. By providing the limiting part 23, it is easy to fix the guide column 8, thereby improving the stability and reliability of the guide column 8 during transportation and flipping.

[0054] Optionally, the limiting part 23 is a plate with a limiting groove, and the limiting part 23 is provided at least two at intervals along the left and right direction.

[0055] In some embodiments, such as Figures 1 to 4 As shown, the top surface of the support frame 2 is provided with a stop plate 24. The stop plate 24 extends in the front-back direction and is located on the side of the support frame 2 near the second frame 6. By setting the stop plate, when the guide column 8 is flipped, the stop plate 24 can provide support for the guide column 8, thereby preventing the guide column 8 from sliding relative to the support frame 2 and improving the reliability and stability of the guide column 8 during transportation and flipping.

[0056] Optionally, two stop plates 24 are provided at intervals along the front-rear direction. While maintaining the same stopping effect on the guide column 8, the size of the stop plates 24 is reduced, thereby reducing the weight of the bracket itself and facilitating transportation.

[0057] In some embodiments, such as Figures 1 to 4 As shown, the stop plate 24 is provided with an anti-slip part 241, which is used to fit against the end face of the column. By setting the anti-slip part 241, the support and limiting effect of the stop plate 24 on the guide column 8 is further improved, making it safe and reliable.

[0058] In some embodiments, such as Figures 1 to 4 As shown, the stop plate 24 is provided with an arc-shaped limiting plate segment 25. The limiting plate segment 25, the stop plate 24 and the support frame 2 form a limiting cavity for placing one end of the guide column 8. By setting the limiting plate segment 25, the support and limiting of one end of the guide column 8 are further realized, thereby improving the stability and reliability during the flipping operation.

[0059] In some embodiments, such as Figures 1 to 4 As shown, the second frame 6 is provided with an arc-shaped guide rail 61, and the first rotating shaft 21 is provided with a guide rod 7 that is fixedly connected to the support frame 2. The other end of the guide rod 7 is slidably engaged with the guide rail 61.

[0060] In this embodiment, by setting guide rod 7 and guide rail, the rotation direction of support frame 2 is further constrained, thereby improving the stability and safety of support frame 2 during rotation.

[0061] Optionally, one end of the guide rod 7 is rotatably mounted on the first rotating shaft 21 and fixedly connected to the support frame 2.
