Description

Technical Field

[0001] This utility model relates to the technical field of nuclear fuel element production equipment in the nuclear industry, specifically to a fluidization tube and gas distributor temporary storage device. Background Technology

[0002] In the production of nuclear fuel elements in the nuclear industry, fluidization tubes and gas distributors are currently stored on simple shelves or directly stacked. The storage process requires manual handling of the fluidization tubes and gas distributors to the storage area, and they are then manually retrieved when needed. Since the gas distributors are located at the ends of the fluidization tubes, they must be manually separated before storage. Improper handling during the manual handling of fluidization tubes and gas distributors, and during the separation of distributors, can easily lead to collisions, causing scratches on the equipment surface, loosening of parts, and other damage. Furthermore, manual handling is inefficient, especially when there are many pieces of equipment, consuming a significant amount of manpower and time, severely impacting production efficiency. Frequent manual handling is also physically demanding, easily leading to employee fatigue and further increasing the risk of operational errors. In addition, simple storage areas cannot provide adequate protection for the equipment; long-term exposure to the production environment makes the equipment susceptible to corrosion from dust and moisture, accelerating aging and damage. Therefore, how to conveniently store and separate fluidization tubes and gas distributors has become an urgent problem to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a fluidizing tube and gas distributor temporary storage device to solve at least one of the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fluidizing tube and gas distributor temporary storage device includes a housing with a door panel assembly on the front. Inside the housing are a turntable assembly and a clamping mechanism. The turntable assembly has multiple cylindrical temporary storage fixtures spaced circumferentially. These cylindrical temporary storage fixtures are used to hold the fluidizing tube and gas distributor, and their internal limiting height is higher than the height of the gas distributor. A cylindrical temporary storage fixture located at the loading station is a loading fixture. Both sides of the cylindrical temporary storage fixture have arc-shaped openings communicating with the interior. The clamping mechanism includes a left cylinder, a right cylinder, a left clamping arm, and a right clamping arm. The left and right cylinders respectively drive the left and right clamping arms to move, and the clamping portions of the left and right clamping arms pass through the arc-shaped openings to clamp the gas distributor located inside the loading fixture.

[0006] This technical solution relates to a temporary storage device used in the nuclear fuel element production process of the nuclear industry for storing fluidized bed tubes and gas distributors to be cleaned and after cleaning. Specifically, the front of the device shell is equipped with a door panel assembly, which facilitates loading and unloading by opening the door panel assembly. The loading and unloading operations are connected to external lifting equipment, which sequentially lifts the fluidized bed tubes and gas distributors into the loading fixture. Closing the door panel assembly provides good protection for the equipment. The turntable assembly has multiple cylindrical temporary storage fixtures spaced circumferentially. The shape of the cylindrical temporary storage fixtures is set according to the specific shape and size of the fluidized bed tubes and gas distributors. The cylindrical temporary storage fixtures are used to hold the fluidized bed tubes and gas distributors. During storage, the fluidized bed tubes and gas distributors are inserted vertically into the cylindrical temporary storage fixtures. The internal limiting height of the cylindrical temporary storage fixtures is higher than the height of the gas distributors. The portion of the cylindrical temporary storage fixtures extending beyond the gas distributors restricts the lower end of the fluidized bed tubes, improving the stability of the entire fluidized bed tube and gas distributor inserted into the cylindrical temporary storage fixtures. Furthermore, the clamping mechanism includes a left cylinder, a right cylinder, a left clamping arm, and a right clamping arm. The left and right cylinders drive the left and right clamping arms respectively. The clamping parts of the left and right clamping arms pass through the arc-shaped opening and clamp the gas distributor located inside the loading fixture. The clamping mechanism can fix the gas distributor inside the cylindrical temporary storage fixture. After the gas distributor is fixed, the external lifting equipment can extract the fluidizing tube, thereby achieving the separation of the fluidizing tube and the gas distributor. This technical solution can complete the separation of the fluidizing tube and the gas distributor within the cylindrical temporary storage fixture, facilitating the storage and separation of the fluidizing tube and the gas distributor before and after cleaning. It solves the problems of collision damage easily caused by traditional manual handling and the reliance on manual experience for separation in traditional equipment.

[0007] Furthermore, since the gas distributor is located inside the cylindrical temporary storage fixture, a gas distributor pick-and-place mechanism is also included to facilitate the removal of the gas distributor and avoid damage to it. This mechanism includes a rotating baffle, a rotating drive cylinder, an extraction cylinder, a vacuum suction cup, and the gas distributor temporary storage fixture. The equipment housing has a gas distributor inlet. The rotating baffle is rotatably connected to the gas distributor inlet. The rotating drive cylinder drives the rotating baffle to rotate, and the rotation axis of the rotating baffle is parallel to the rotation axis of the turntable. The extraction cylinder is mounted on the rotating baffle and drives the vacuum suction cup to rise and fall. The gas distributor temporary storage fixture is located outside the equipment housing. The cylindrical temporary storage fixture at the pick-up station is the pick-up fixture. After the vacuum suction cup picks up the gas distributor inside the pick-up fixture, it transfers the gas distributor to the gas distributor temporary storage fixture.

[0008] In practice, after the fluidizing tube is separated from the gas distributor, the cylindrical temporary storage fixture on the turntable rotates to the gas distributor's material handling position, which is close to the gas distributor's handling mechanism. At this point, the gas distributor's handling mechanism needs to complete the material handling operation. Specifically, the rotary drive cylinder drives the rotary baffle to rotate, and the extraction cylinder and vacuum suction cup move together with the rotary baffle to directly above the gas distributor's material handling position. The extraction cylinder drives the vacuum suction cup to descend until it approaches the gas distributor. After the vacuum suction cup adsorbs the gas distributor in the material handling fixture, it transfers the gas distributor to the gas distributor's temporary storage fixture. Subsequently, the gas distributor is transferred using external equipment. The vacuum suction cup uses the principle of negative pressure to adsorb the gas distributor, avoiding the scratches caused to the equipment surface by traditional gripping methods.

[0009] Furthermore, in order to adjust the height of the extraction cylinder as needed, the rotating baffle is provided with an adjusting cylinder and a vertical slide rail, and the adjusting cylinder drives the extraction cylinder to move along the vertical slide rail.

[0010] Furthermore, in order to better control the extension and retraction of the vacuum tube, the vacuum suction cup is connected to a spring suction tube, and the spring suction tube is provided with an air tube gauge tube.

[0011] Furthermore, during the feeding process, in order to detect whether there are any obstacles inside the cylindrical temporary storage fixture, a through-beam sensor is also included. The cylindrical temporary storage fixture is provided with a left-side through hole and a right-side through hole, and the through-beam sensor is located directly opposite the left-side through hole and the right-side through hole of the feeding fixture.

[0012] Furthermore, to achieve a small footprint, high stability, and good sealing effect when opening and closing the doors, the door panel assembly includes a left door and a right door, forming a double-door structure. Both the left and right doors are L-shaped door panels, which slide against the equipment housing. The upper end of the equipment housing is equipped with left-side door cylinders and right-side door cylinders, respectively, for driving the left and right doors. When the equipment is in storage mode, the double doors are closed, effectively preventing external dust and moisture from entering the storage area. When the equipment needs to be retrieved or placed, the cylinders drive the double doors to slide open along a linear guide rail.

[0013] Furthermore, in order to better drive the left and right clamping arms and achieve a better clamping effect, the left and right cylinders are fixed to the equipment housing. The left and right clamping arms are rotatably connected to the equipment housing through bearing seats and bearings. Both the left and right clamping arms are provided with strip-shaped holes. The ends of the piston rods of the left and right cylinders slide in cooperation with the strip-shaped holes through roller bearings. The clamping parts of the left and right clamping arms are both arc-shaped clamping parts.

[0014] Furthermore, the turntable assembly includes a turntable, a push cylinder assembly, and a positioning cylinder assembly. The push cylinder assembly drives the turntable to rotate, and the positioning cylinder assembly locks the rotation position of the turntable.

[0015] Because the positioning cylinder assembly locks the turntable's rotation position, the locked state of the turntable facilitates subsequent separation operations of the fluidizing tube and gas distributor. By driving the turntable to rotate using the cylinder assembly, multiple cylindrical temporary storage fixtures can be sequentially rotated to their corresponding positions during the part-picking and-placing process, thus providing convenience for subsequent part-picking and-placing operations.

[0016] Furthermore, to ensure the turntable remains stable during the loading and unloading process, thus facilitating smooth loading and unloading operations, the lower end face of the turntable is provided with multiple positioning posts. The pushing cylinder assembly and the positioning cylinder assembly are both located below the turntable. The pushing cylinder assembly includes a pushing cylinder, a fixed push plate, and an elastic push plate. The fixed push plate is mounted on the drive rod of the pushing cylinder. The fixed push plate has an opening slot on the side near the positioning post. The elastic push plate is rotatably mounted in the opening slot. The rotation axis of the elastic push plate is perpendicular to the extension direction of the drive rod. A limiting block is provided behind the opening slot. During the extension of the drive rod of the pushing cylinder, the elastic push plate pushes the positioning post in front of it. During the retraction of the drive rod of the pushing cylinder, the elastic push plate avoids the positioning post behind it.

[0017] The positioning cylinder assembly includes a positioning cylinder and a V-shaped positioning head disposed at the end of the positioning cylinder. When the positioning cylinder extends, it drives the V-shaped positioning head to move toward the corresponding positioning post until the V-shaped opening of the V-shaped positioning head abuts against the positioning post.

[0018] Furthermore, in order to better drive and lock the turntable, the angle between the first positioning post facing the positioning cylinder assembly and the second positioning post in front of the elastic push plate is 90 degrees.

[0019] The beneficial effects of this utility model are as follows: This technical solution relates to a temporary storage device used in the nuclear fuel element production process of the nuclear industry for storing fluidized bed tubes and gas distributors to be cleaned and after cleaning. Specifically, the front of the device shell is provided with a door panel assembly, which facilitates loading and unloading by opening the door panel assembly. Specifically, the loading and unloading operation can be connected with external lifting equipment. The external lifting equipment lifts the fluidized bed tubes and gas distributors into the loading fixture in sequence. By closing the door panel assembly, good protection can be provided for the equipment. Since the turntable assembly has multiple cylindrical temporary storage fixtures spaced circumferentially, the shape of the cylindrical temporary storage fixtures is set according to the specific shape and size of the fluidized bed tubes and gas distributors. The cylindrical temporary storage fixtures are used to place the fluidized bed tubes and gas distributors. Specifically, during storage, the fluidized bed tubes and gas distributors are inserted vertically into the cylindrical temporary storage fixtures. The internal limiting height of the cylindrical temporary storage fixtures is higher than the height of the gas distributors. The part of the cylindrical temporary storage fixtures that extends beyond the gas distributors can restrict the lower end of the fluidized bed tubes, improving the stability of the fluidized bed tubes and gas distributors when inserted into the cylindrical temporary storage fixtures. Furthermore, the clamping mechanism includes a left cylinder, a right cylinder, a left clamping arm, and a right clamping arm. The left and right cylinders drive the left and right clamping arms respectively. The clamping parts of the left and right clamping arms pass through the arc-shaped opening and clamp the gas distributor located inside the loading fixture. The clamping mechanism can fix the gas distributor inside the cylindrical temporary storage fixture. After the gas distributor is fixed, the external lifting equipment can extract the fluidizing tube, thereby achieving the separation of the fluidizing tube and the gas distributor. This technical solution can complete the separation of the fluidizing tube and the gas distributor within the cylindrical temporary storage fixture, facilitating the storage and separation of the fluidizing tube and the gas distributor before and after cleaning. It solves the problems of collision damage easily caused by traditional manual handling and the reliance on manual experience for separation in traditional equipment. Attached Figure Description

Detailed Implementation

[0033] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0034] Example 1:

[0035] like Figures 1-12 As shown, this embodiment provides a fluidizing tube and gas distributor temporary storage device, including a device housing 1. The front of the device housing 1 is provided with a door panel assembly. The inside of the device housing 1 is provided with a turntable assembly and a clamping mechanism. The turntable 2 of the turntable assembly is circumferentially spaced with multiple cylindrical temporary storage fixtures 3. The cylindrical temporary storage fixtures 3 are used to place the fluidizing tube 4 and the gas distributor 5. The internal limiting height of the cylindrical temporary storage fixtures 3 is higher than the height of the gas distributor 5. The cylindrical temporary storage fixture 3 located at the loading station is a loading fixture 6. The cylindrical temporary storage fixture 3 has arc-shaped openings 7 on both sides that communicate with the interior. The clamping mechanism includes a left cylinder 8, a right cylinder 9, a left clamping arm 10 and a right clamping arm 11. The left cylinder 8 and the right cylinder 9 drive the left clamping arm 10 and the right clamping arm 11 to move respectively. The clamping parts of the left clamping arm 10 and the right clamping arm 11 pass through the arc-shaped openings 7 to clamp the gas distributor 5 located in the loading fixture 6.

[0036] This technical solution relates to a temporary storage device used in the nuclear fuel element production process of the nuclear industry for storing fluidized pipes 4 to be cleaned and gas distributors 5 after cleaning. Specifically, the front of the equipment shell 1 is provided with a door panel assembly, which facilitates loading and unloading by opening the door panel assembly. Specifically, the loading and unloading operation can be connected with external lifting equipment. The external lifting equipment lifts the fluidized pipes 4 and gas distributors 5 into the loading fixture 6 in sequence. By closing the door panel assembly, good protection can be provided for the equipment. Because the turntable 2 of the turntable assembly is circumferentially spaced with multiple cylindrical temporary storage fixtures 3, the shape of the cylindrical temporary storage fixtures 3 is set according to the specific shape and size of the fluidizing tube 4 and the gas distributor 5. The cylindrical temporary storage fixtures 3 are used to place the fluidizing tube 4 and the gas distributor 5. When storing, the fluidizing tube 4 and the gas distributor 5 are inserted vertically into the cylindrical temporary storage fixtures 3. The internal limiting height of the cylindrical temporary storage fixtures 3 is higher than the height of the gas distributor 5. The part of the cylindrical temporary storage fixtures 3 that exceeds the gas distributor 5 can limit the lower end of the fluidizing tube 4, thereby improving the stability of the fluidizing tube 4 and the gas distributor 5 as a whole when inserted into the cylindrical temporary storage fixtures 3. Furthermore, since the clamping mechanism includes a left cylinder 8, a right cylinder 9, a left clamping arm 10, and a right clamping arm 11, the left cylinder 8 and the right cylinder 9 respectively drive the left clamping arm 10 and the right clamping arm 11 to move. The clamping parts of the left clamping arm 10 and the right clamping arm 11 pass through the arc-shaped opening 7 to clamp the gas distributor 5 located in the loading fixture 6. The clamping mechanism can fix the gas distributor 5 in the cylindrical temporary storage fixture 3. After the gas distributor 5 is fixed, the external lifting equipment can extract the fluidizing tube 4, thereby realizing the separation of the fluidizing tube 4 and the gas distributor 5. This technical solution can complete the separation of the fluidizing tube 4 and the gas distributor 5 in the cylindrical temporary storage fixture 3, which facilitates the storage and separation of the fluidizing tube 4 and the gas distributor 5 before and after cleaning, and solves the problems of collision damage caused by traditional manual handling and the reliance on manual experience for separation in traditional equipment.

[0037] Example 2:

[0038] This embodiment is an optimization based on the above embodiment 1.

[0039] Since the gas distributor 5 is located inside the cylindrical temporary storage fixture 3, a gas distributor pick-and-place mechanism is also included to facilitate the removal of the gas distributor 5 and avoid damage to it. This mechanism includes a rotating baffle 12, a rotating drive cylinder 13, an extraction cylinder 14, a vacuum suction cup 15, and a gas distributor temporary storage fixture 16. The external dimensions of the gas distributor temporary storage fixture 16 match the external dimensions of the gas distributor. A gas distributor inlet 17 is provided on the equipment housing 1. The rotating baffle 12 and the gas distributor inlet 17... The 7 parts are rotatably connected by bearing part 46. Rotary drive cylinder 13 drives rotating baffle 12 to rotate. The rotation axis of rotating baffle 12 is parallel to the rotation axis of turntable 2. Extraction cylinder 14 is set on rotating baffle 12. Extraction cylinder 14 drives vacuum suction cup 15 to rise and fall. Gas distributor temporary storage fixture 16 is set outside the equipment shell 1. The cylindrical temporary storage fixture 3 located at the material picking station is the material picking fixture 18. After vacuum suction cup 15 picks up gas distributor 5 in material picking fixture 18, it transfers gas distributor 5 to gas distributor temporary storage fixture 16.

[0040] In specific operation, after the fluidizing tube 4 is separated from the gas distributor 5, the cylindrical temporary storage fixture 3 on the turntable 2 rotates to the gas distributor picking position, which is close to the gas distributor picking and placing mechanism. At this time, the gas distributor picking and placing mechanism needs to complete the picking work. Specifically, the rotary drive cylinder 13 drives the rotary baffle 12 to rotate, and the extraction cylinder 14 and vacuum suction cup 15 move together with the rotary baffle 12 to directly above the gas distributor picking position. The extraction cylinder 14 drives the vacuum suction cup 15 to descend until the vacuum suction cup 15 is close to the gas distributor 5. After the vacuum suction cup 15 adsorbs the gas distributor 5 in the picking fixture 18, it transfers the gas distributor 5 to the gas distributor temporary storage fixture 16. Subsequently, the gas distributor 5 is transferred by external equipment. The vacuum suction cup 15 uses the principle of negative pressure to adsorb the gas distributor 5, avoiding the scratching of the equipment surface caused by traditional gripping methods. Preferably, in order to facilitate the connection with external equipment, the gas distributor picking and placing mechanism is set on the back of the equipment shell 1, that is, the side opposite to the door panel assembly.

[0041] Example 3:

[0042] This embodiment is an optimization based on the above embodiment 2.

[0043] In order to adjust the height of the extraction cylinder 14 as needed, the rotating baffle 12 is provided with an adjusting cylinder 19 and a vertical slide rail 20. The adjusting cylinder 19 drives the extraction cylinder 14 to move along the vertical slide rail 20.

[0044] Example 4:

[0045] This embodiment is an optimization based on the above embodiment 2.

[0046] In order to better control the extension and retraction of the vacuum tube, the vacuum suction cup 15 is connected to a spring suction tube 21, and the spring suction tube 21 is provided with an air tube gauge tube 22.

[0047] Example 5:

[0048] This embodiment is an optimization based on the above embodiment 1.

[0049] During material loading, in order to detect whether there are any obstacles inside the cylindrical temporary storage fixture 3, a through-beam sensor 23 is also included. The cylindrical temporary storage fixture 3 is provided with a left through hole 24 and a right through hole 25. The through-beam sensor 23 is located directly opposite the left through hole 24 and the right through hole 25 of the material loading fixture 6.

[0050] Example 6:

[0051] This embodiment is an optimization based on the above embodiment 1.

[0052] To achieve a small footprint, high stability, and good sealing effect when opening and closing the doors, the door assembly includes a left door 26 and a right door 27, forming a double-door structure. Both the left door 26 and the right door 27 are L-shaped door panels, which slide against the equipment housing 1. The upper end of the equipment housing 1 is equipped with a left door cylinder 28 and a right door cylinder 29, respectively, for driving the left door 26 and the right door 27. When the equipment is in storage mode, the double doors are closed, effectively preventing external dust and moisture from entering the storage area.

[0053] To improve the smoothness of opening and closing the doors, the upper part of the equipment housing 1 is provided with a top track 30 and a lower track 31. The upper end plates of the left door 26 and the right door 27 move along the top track 30, and the side end plates of the left door 26 and the right door 27 are provided with rollers 32, which move along the lower track 31. When it is necessary to pick up or put down the equipment, the cylinder drives the double doors to slide open along the guide rails.

[0054] Example 7:

[0055] This embodiment is an optimization based on the above embodiment 1.

[0056] To better drive the left clamping arm 10 and the right clamping arm 11 and achieve a better clamping effect, the left cylinder 8 and the right cylinder 9 are fixed on the equipment housing 1. The left clamping arm 10 and the right clamping arm 11 are rotatably connected to the equipment housing 1 through the bearing seat 33 and the bearing. Both the left clamping arm 10 and the right clamping arm 11 are provided with a strip hole 34. The end of the piston rod of the left cylinder 8 and the right cylinder 9 slides in cooperation with the strip hole 34 through the roller bearing 35. The clamping part of the left clamping arm 10 and the right clamping arm 11 is an arc-shaped clamping part 36.

[0057] Example 8:

[0058] This embodiment is an optimization based on the above embodiment 1.

[0059] The turntable assembly includes a turntable 2, a push cylinder assembly, and a positioning cylinder assembly. The push cylinder assembly drives the turntable 2 to rotate, and the positioning cylinder assembly locks the rotation position of the turntable 2.

[0060] Because the cylinder assembly drives the turntable 2 to rotate, multiple cylindrical temporary storage fixtures 3 can be rotated sequentially to their corresponding positions during the part picking and placing process, thus facilitating subsequent part picking and placing operations. Since the positioning cylinder assembly locks the rotation position of the turntable 2, the locked state of the turntable 2 facilitates subsequent separation operations of the fluidizing tube 4 and the gas distributor 5.

[0061] Example 9:

[0062] This embodiment is an optimization based on the above embodiment 8.

[0063] To ensure the stability of the turntable 2 during the loading and unloading process, thus facilitating the smooth operation of the loading and unloading work, the lower end face of the turntable 2 is provided with multiple positioning posts 37. The push cylinder assembly and the positioning cylinder assembly are both located below the turntable 2. The push cylinder assembly includes a push cylinder 38, a fixed push plate 39, and an elastic push plate 40. The fixed push plate 39 is mounted on the drive rod of the push cylinder 38. The fixed push plate 39 has an opening slot 41 on the side near the positioning post 37. The elastic push plate 40 is rotatably mounted in the opening slot 41. The rotation axis of the elastic push plate 40 is perpendicular to the extension direction of the drive rod. A limit block 42 is provided behind the opening slot 41. During the extension of the drive rod of the push cylinder 38, the elastic push plate 40 pushes the positioning post 37 located in front of it. During the retraction of the drive rod of the push cylinder 38, the elastic push plate 40 avoids the positioning post 37 located behind it.

[0064] The positioning cylinder assembly includes a positioning cylinder 43 and a V-shaped positioning head 44 disposed at the end of the positioning cylinder 43. When the positioning cylinder 43 extends, it drives the V-shaped positioning head 44 to move toward the corresponding positioning post 37 until the V-shaped opening of the V-shaped positioning head 44 abuts against the positioning post 37.

[0065] Specifically, the cylinder 38 drives the fixed push plate 39 to move forward. The elastic push plate 40 on the fixed push plate 39 pushes the positioning post 37 in front of it and drives the turntable 2 to rotate. In this step, the limiting block 42 set behind the opening slot 41 can keep the elastic push plate 40 stable during the process of pushing the positioning post 37 forward. After the turntable 2 completes one rotation (the positioning post 37 is located in the position directly opposite the V-shaped positioning head 44), the positioning cylinder 43 is started. The positioning cylinder 43 extends and drives the V-shaped positioning head 44 to move toward the corresponding positioning post 37 until the V-shaped opening of the V-shaped positioning head 44 abuts against the positioning post 37, thereby locking the turntable 2 after one rotation. This stabilizes the positions of the fluidizing pipe 4 and the gas distributor 5 located at the part picking and placing station, so that the subsequent part picking and placing work can proceed smoothly.

[0066] After one loading and unloading operation is completed, the next rotation drive is required. The V-shaped positioning head 44 remains in contact with the positioning post 37. Then, the push cylinder 38 drives the fixed push plate 39 to move backward. The rear end of the elastic push plate 40 abuts against the positioning post 37 located behind it. As it continues to move backward, the positioning post 37 pushes the elastic push plate 40 forward until the elastic push plate 40 disengages from the positioning post 37 and the positioning post 37 is positioned in front of the elastic push plate 40. Subsequently, the positioning post 37 located in front of the elastic push plate 40 can be pushed again. The positioning cylinder assembly needs to release the lock on the corresponding positioning post 37. Preferably, both the push cylinder 38 and the positioning cylinder 43 are three-axis cylinders. The three-axis cylinders work together to precisely control the rotation angle.

[0067] Example 10:

[0068] This embodiment is an optimization based on the above embodiment 9.

[0069] To better drive and lock the turntable 2, the angle between the first positioning post 37.1 facing the positioning cylinder assembly and the second positioning post 37.2 in front of the elastic push plate 40 is 90 degrees. The positioning cylinder assembly and the push cylinder assembly work together to ensure the precise rotation angle of the turntable 2.

[0070] With the continuous improvement of industrial automation, nuclear fuel element production lines in the nuclear industry have widely adopted technologies such as automated conveying and precise control. However, traditional storage and transfer processes still rely on manual handling. From the completion of material production to its entry into the storage area, and then its retrieval from the transfer point for subsequent production, the entire process is difficult to seamlessly integrate with automated production lines. This technical solution can also interact and link with other automated equipment on the production line to achieve intelligent control of equipment storage and transfer processes. To ensure the cleanliness of the storage space, a dust absorption mechanism 45 is also provided.

[0071] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
