DETAILED DESCRIPTION

[0013] In the following, exemplary embodiments of the present application will be described with reference to the drawings. In the description, not all the features of the actual embodiments are described for the sake of clarity and conciseness. It should be appreciated, however, that many embodiment-specific decisions must be made in developing any such actual embodiment to achieve the specific goals of the developer, such as compliance with system- and business-related constraints, which can vary from one embodiment to another. Moreover, it should be appreciated that, while the development work can potentially be very complex and time-consuming, it would be a routine undertaking for those with ordinary skill in the art having the benefit of this disclosure.

[0014] It should also be noted here that, in order not to obscure the present application with unnecessary detail, only the device structures and / or processing steps closely related to the solution according to the present application are shown in the drawings, while other details less relevant to the present application are omitted.

[0015] It should be noted that the technical or scientific terms used in the present application should be understood as having their usual meaning for a person with ordinary skills in the art, unless otherwise defined.

[0016] In the description of embodiments of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly and specifically limited.

[0017] Traditional hoisting equipment typically requires moving the overhead crane hook to select lifting points during the hoisting of fuel rod assemblies. Then, slings are manually attached to the fuel rod assemblies. This method cannot automatically grip and unload the fuel rod assemblies, necessitating repeated manual adjustments to the sling positions. This not only increases operating time and labor costs but also increases the risk of safety hazards due to human error. For example, heavy fuel rod assemblies are prone to bending and deformation during horizontal hoisting, affecting the structural integrity of the fuel rod assembly and its subsequent safety.

[0018] In related technologies, some hoisting equipment is equipped with multi-point fixing or auxiliary support structures, but this increases the operational complexity of the hoisting equipment and is not suitable for remote operation in hot chambers or high-radiation environments.

[0019] To address the aforementioned technical problems, embodiments of this application provide a hoisting device suitable for fuel rod assemblies. Figure 1 This is a structural schematic diagram of the hoisting device according to an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the lifting device after omitting the part of the structure that houses the components. Figure 3 This is a schematic diagram of the cooperation structure between the hoisting device and the fuel rod assembly according to an embodiment of this application, as shown below. Figures 1 to 3 As shown, the hoisting device may include at least a receiving assembly 10, a clamping assembly 20, and a hoisting assembly 30. The receiving assembly 10 is configured to receive the fuel rod assembly 50 and the clamping assembly 20; the clamping assembly 20 is configured to move relative to the receiving assembly 10, allowing the fuel rod assembly 50 to enter the receiving assembly 10 when the clamping assembly 20 moves to a first state, and clamping the fuel rod assembly 50 when the clamping assembly 20 moves to a second state; the hoisting assembly 30 is configured to lift the receiving assembly 10 and the clamping assembly 20 to transfer the fuel rod assembly 50 clamped by the clamping assembly 20 to the next work station.

[0020] The hoisting device provided in the embodiments of this application configures the clamping component 20 to move relative to the receiving component 10, allowing the fuel rod assembly 50 to enter or leave the receiving component 10. This allows for automatic clamping or release of the fuel rod assembly 50 through the cooperation between the clamping component 20 and the receiving component 10, eliminating the need for manual intervention in hoisting the fuel rod assembly 50. Furthermore, the hoisting device of this application has a relatively simple structure and operation process, facilitating stable gripping and unloading of the fuel rod assembly 50. It is suitable for remote operation in hot chambers or high-radioactive environments. Simultaneously, the cooperation between the hoisting component 30, the receiving component 10, and the clamping component 20 enables vertical hoisting of the fuel assembly, which helps prevent deformation of the fuel rod assembly 50 during hoisting, ensuring the structural integrity of the fuel rod assembly 50 and its safety in subsequent use.

[0021] In some embodiments, the lifting assembly 30 can cooperate with a transfer device to lift the lifting assembly 30 after the fuel rod assembly 50 is held by the clamping assembly 20, thereby transferring the fuel rod assembly 50.

[0022] In some embodiments, Figure 4 yes Figure 1 The sectional view of the hoisting device shown is as follows: Figure 4 As shown, the hoisting assembly 30 may include a hoisting fitting 31 and a hoisting support 32. The hoisting fitting 31 is used to cooperate with the transfer equipment, and the hoisting support 32 is fixedly connected to the hoisting fitting 31 to support the receiving assembly 10, the clamping assembly 20, and the fuel rod assembly 50 clamped by the clamping assembly 20, so as to realize the transfer of the fuel rod assembly 50.

[0023] In some embodiments, the clamping assembly 20 includes a rotating assembly 21, a guide member 22, and a clamping member 23. The receiving assembly 10 has a first guide groove 111. The rotating assembly 21 is disposed within the receiving assembly 10 and is configured to move along the axial direction of the receiving assembly 10. The guide member 22 is disposed within the first guide groove 111 and is detachably connected to the rotating assembly 21, and is used to provide guidance for the rotating assembly 21 when it moves along the axial direction of the receiving assembly 10. The rotating assembly 21 is also configured to rotate relative to the receiving assembly 10 when it moves along the axial direction of the receiving assembly 10, so as to drive the clamping member 23 to move during the rotation, so that the clamping member 23 moves to a first state and a second state.

[0024] The hoisting device provided in the embodiments of this application sets the clamping component 20 into a structure including a rotating component 21, a guide member 22 and a clamping member 23. The guide member 22 and the first guide groove 111 of the receiving component 10 are used to guide the rotating component 21 in motion, ensuring that the movement trajectory of the rotating component 21 can meet the requirements and that the movement of the rotating component 21 is stable.

[0025] In some embodiments, such as Figures 1 to 4 As shown, a plurality of first guide grooves 111 can be formed on the receiving component 10, and each first guide groove 111 is configured to extend along the axial direction of the receiving component 10, so as to enable movement along the axial direction of the receiving component 10, while further improving the smoothness of the movement of the rotating component 21.

[0026] In some embodiments, such as Figures 1 to 4As shown, the rotating assembly 21 includes a support member 211 and a rotating member 212. The receiving assembly 10 has a rotating guide portion 112. The support member 211 and the guide member 22 are detachably connected and configured to move along the axial direction of the receiving assembly 10. The rotating member 212 is sleeved on the support member 211 and has a second guide groove 2121. The rotating guide portion 112 is disposed in the second guide groove 2121. During the movement of the rotating guide portion 112 along the second guide groove 2121, the rotating member 212 can rotate relative to the receiving assembly 10. The rotating member 212 forms a third guide groove 2122. The clamping member 23 is disposed in the third guide groove 2122 and configured to move along the third guide groove 2122 during the rotation of the rotating member 212 relative to the receiving assembly 10.

[0027] The hoisting device provided in the embodiments of this application has a rotating member 212 disposed outside the support member 211. When the support member 211 moves along the axial direction of the receiving assembly 10, the rotating guide part 112 on the receiving assembly 10 can move along the second guide groove 2121, thereby driving the rotating member 212 to rotate. When the rotating member 212 rotates, the clamping member 23 disposed in the third guide groove 2122 on the rotating member 212 can move along the third guide groove 2122 as the rotating member 212 rotates, thereby achieving the purpose of the clamping member 23 automatically clamping or releasing the fuel rod assembly 50.

[0028] In some embodiments, Figure 5 This is a cross-sectional structural schematic diagram of a hoisting device according to an embodiment of this application. Figure 6 This is a cross-sectional structural schematic diagram of a hoisting device according to another embodiment of this application, as shown below. Figure 5 and Figure 6 As shown, the clamping member 23 includes multiple elastic parts 231 and multiple clamping parts 232. The third guide groove 2122 consists of multiple recesses formed by the inner wall of the rotating member 212 recessed outwards. The elastic parts 231, clamping parts 232, and recesses are arranged in a one-to-one correspondence. The clamping part 232 is disposed in the recess, and the elastic part 231 is sleeved on the clamping part 232. During the rotation of the rotating member 212, the clamping part 232 can enter or leave the recess under the drive of the elastic part 231. When the clamping part 232 enters the recess, the clamping part 232 is in a first state, and when the clamping part 232 leaves the recess, the clamping part 232 is in a second state.

[0029] The hoisting device provided in the embodiments of this application sets the third guide groove 2122 into a plurality of recesses formed by the inner wall of the rotating member 212 recessed outwards. Then, the clamping member 23 is set into a structure including an elastic part 231 and a clamping part 232. During the rotation of the rotating member 212, the elastic force of the elastic part 231 can be used to drive the clamping part 232 to move inside or outside the recess, thereby realizing the switching between the first state and the second state. Without the need for a complex drive structure, the clamping member 23 can automatically clamp or release the fuel rod assembly 50.

[0030] In some embodiments, Figure 7 This is a schematic diagram of the rotating component according to an embodiment of this application, as shown below. Figure 7 As shown, the second guide groove 2121 includes a plurality of first guide portions 21211, a plurality of second guide portions 21212, and a plurality of third guide portions 21213. Each first guide portion 21211 has a first end connected to a second end of a third guide portion 21213, forming a first positioning portion 21214. The second end of each first guide portion 21211 is connected to the first end of a second guide portion 21212 and the first end of a third guide portion 21213. The second guide portion 21212 has a predetermined angle between its two ends and the first end of the third guide portion 21213. The second guide portion 21212 extends along the axial direction of the rotating member 212, and the second end of the second guide portion 21212 forms the second positioning portion 21215. When the rotating guide portion 112 moves from the first positioning portion 21214 to the second positioning portion 21215, the clamping portion 232 enters the recess. When the rotating guide portion 112 moves from the second positioning portion 21215 to the first positioning portion 21214, the clamping portion 232 leaves the recess.

[0031] The hoisting device provided in the embodiments of this application has a structure in which the second guide groove 2121 is connected to the first guide part 21211, the second guide part 21212 and the third guide part 21213, which can realize the circumferential rotation of the rotating member 212. The second end of the first guide part 21211 and the first end of the third guide part 21213 are set to have a predetermined angle. When the rotating guide part 112 rotates from the previous first positioning part 21214 to the next first positioning part 21214, the rotation angle of the rotating member 212 is fixed, thereby realizing the positioning rotation of the rotating member 212.

[0032] In some embodiments, such as Figure 7 As shown, the multiple second guide sections 21212 are not interconnected.

[0033] In some embodiments, the support member 211 includes a support connection portion and a support body. Figure 8This is a schematic diagram of the structure of the support body according to an embodiment of this application. Figure 9 yes Figure 8 The cross-sectional view of the supporting body shown. Figure 10 This is a structural schematic diagram of the support connection portion according to an embodiment of this application, as shown below. Figure 4 , Figures 8 to 10 As shown, the support connection 2111 is detachably connected to the guide member 22, and the support body 2112 is detachably connected to the support connection 2111. The support body 2112 has a plurality of through grooves 21121, and the through grooves 21121 and the third guide groove 2122 are arranged in a one-to-one correspondence.

[0034] The hoisting device provided in the embodiments of this application has a plurality of through slots 21121 formed on the support body 2112 of the support member 211. The clamping part 232 can enter the accommodating space 110 through the through slots and then clamp the fuel rod assembly 50 in the accommodating space 110.

[0035] In some embodiments, the support body 2112 further forms a limiting engagement portion 21122, and the rotating assembly 21 further includes a limiting member 24. The limiting member 24 is disposed above the clamping portion 232 through the limiting engagement portion 21122 to limit the clamping portion 232 and prevent the clamping portion 232 from rotating during movement.

[0036] In some embodiments, Figure 11 This is a schematic diagram of the clamping part according to an embodiment of this application, as shown below. Figure 11 As shown, one end of the clamping part 232 used to clamp the fuel rod assembly 50 can be configured in a wedge shape to facilitate clamping the fuel rod assembly 50.

[0037] In some embodiments, the clamping part 232 is formed with a clamping limiting part 2321, and the limiting member 24 may be disposed in the limiting part to prevent the clamping part 232 from rotating during movement.

[0038] In some embodiments, a connection positioning groove 21111 is formed at the bottom of the support connection portion 2111, which is used to position the support body 2112 when it is connected to the support body 2112, so as to facilitate the connection between the support body 2112 and the support connection portion 2111.

[0039] In some embodiments, a rotation positioning groove 21112 is also formed at the bottom of the support connection part 2111. The rotation positioning groove 21112 is used to position the rotating part and limit the rotating part during the rotation process to ensure that the rotating part can rotate stably.

[0040] In some embodiments, the rotation positioning groove 21112 can be a V-shaped groove to ensure the limiting effect on the rotating part.

[0041] In some embodiments, the receiving assembly 10 includes a receiving body 11 and a lifting connector 12. The receiving body 11 forms a receiving space 110 for receiving the fuel rod assembly 50 and the clamping assembly 20. The receiving body 11 is detachably connected to the lifting assembly 30 via the lifting connector 12. The clamping assembly 20 is configured to move relative to the receiving body 11.

[0042] The hoisting device provided in the embodiments of this application uses the receiving space 110 formed by the receiving body 11 to receive the fuel rod assembly 50 and the clamping assembly 20, which can provide support for the clamping assembly 20 and at the same time prevent the clamping assembly 20 and the fuel rod assembly 50 from being damaged.

[0043] In some embodiments, a rotation guide 112 may be formed on the receiving body 11. For example, a screw may be detachably connected to the receiving body 11 to form the rotation guide 112.

[0044] In some embodiments, the receiving body 11 forms a first guide groove 111 for guiding the clamping assembly 20 as it moves relative to the receiving body 11.

[0045] The hoisting device provided in the embodiments of this application uses the receiving component 10 to guide the moving clamping component 20, ensuring that the movement trajectory of the clamping component 20 meets the requirements and that the movement of the clamping component 20 is stable.

[0046] In some embodiments, the hoisting device may further include a motion mating member 40, which is disposed at the bottom of the clamping assembly 20 and is used to reduce the resistance experienced by the clamping assembly 20 during the movement of the clamping assembly 20 relative to the receiving assembly 10, so as to ensure that the clamping assembly 20 can rotate smoothly and stably.

[0047] In some embodiments, the hoisting device may further include a mating support member disposed below the movable mating member 40, and the mating support member having a stepped surface. The stepped surface of the mating support member is used to limit the movable mating member 40, thereby restricting the movable mating member 40 to a defined position and preventing the movable mating member 40 from sliding.

[0048] The process of lifting fuel assemblies using the hoisting device of this application is described in detail below through specific embodiments.

[0049] Example First, the rotating device drives the rotating component 21 in the clamping assembly 20 to approach the mushroom head of the fuel rod assembly 50. When the mushroom head continues to enter the rotating part 212 of the rotating component 21, the rotating part 212 begins to move upward along the axial direction of the receiving body 11 and begins to rotate relative to the receiving body 11.

[0050] Then, when the guide member 22 moves to the top of the first guide groove 111, the rotating guide portion 112 on the receiving body 11 moves from the first positioning portion 21214 to the second positioning portion 21215, and the clamping portion 232 of the clamping member 23 enters the recess, providing space for the mushroom head of the fuel rod assembly 50, so that the mushroom head of the fuel rod assembly 50 can continue to extend into the rotating member 212.

[0051] Then, the drive rotating member 212 continues to rotate, the rotating guide part 112 moves from the second positioning part 21215 to the first positioning part 21214, the clamping part 232 leaves the recess and moves closer to each other, thereby clamping the mushroom head of the fuel rod assembly 50.

[0052] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0053] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
