Description

Technical Field

[0001] This utility model relates to the field of nuclear industry technology, and in particular to a pressure tank opening and closing device for a robotic arm. Background Technology

[0002] High-temperature calcination in hot chambers is mainly used to treat high-level radioactive nuclear waste, especially waste generated from spent fuel elements and nuclear fuel reprocessing. This waste contains radionuclides with extremely long half-lives, such as uranium-235, plutonium-239, strontium-90, and cesium-137, whose radiation energy can last for tens or even hundreds of thousands of years. High-temperature calcination can effectively decompose the organic components and volatile substances in the waste, fix the radionuclides in a stable oxide matrix, reduce their mobility and bioavailability, and significantly reduce the volume of waste through high-temperature treatment, greatly reducing the cost and difficulty of subsequent storage and disposal. During the calcination process, the nuclear waste needs to be placed in a special pressure vessel. After calcination, the pressure vessel needs to be opened. In the existing technology, due to the need for special auxiliary devices, the remote-controlled robotic arm is relatively inconvenient for opening the vessel, especially when opening small pressure vessels, which can easily cause the vessel to tip over, making it inconvenient to use.

[0018] Reference Figures 1 to 6This utility model provides a pressure tank opening and closing device for a robotic arm, comprising: a positioning seat 1, a swing sleeve 2, a socket wrench 3, a connecting piece 4, and a pressure tank 5. The positioning seat 1 includes a disc base 11, on which a fixing post 12 and a guide sleeve 14 are fixedly connected respectively. The fixing post 12 is disposed inside the guide sleeve 14. The swing sleeve 2 includes a positioning sleeve 21, which is rotatably sleeved on the fixing post 12. A connecting rod 22 is fixedly connected to the side end face of the positioning sleeve 21. A ring 23 is fixedly connected to 22. The socket wrench 3 includes an operating rod 31. A crossbar 32 is fixedly connected to the upper end of the operating rod 31. The connector 4 includes a sleeve rod 41. The sleeve rod 41 is movably sleeved inside the ring 23. The length of the sleeve rod 41 is greater than the thickness of the ring 23. A connecting plate 42 is fixedly connected to the lower end of the sleeve rod 41. The operating rod 31 is rotatably mounted on the connecting plate 42. The pressure tank 5 includes a tank body 51. A positioning seat 2 54 is fixedly connected to the bottom surface of the tank body 51. A slot adapted to the fixed column 12 is opened on the bottom surface of the positioning seat 2 54.

[0019] A can lid 52 is provided on the can body 51. Several screws 53 are threadedly connected between the can body 51 and the can lid 52. The bottom surface of the operating rod 31 has a snap-fit ​​interface that matches the nut end of the screws 53. Both ends of the crossbar 32 are fixedly connected to gripping blocks 33. During operation, the slot on the bottom surface of the positioning seat 2 54 is fitted onto the fixed post 12. The robotic arm grips the gripping block 33, causing the snap-fit ​​interface on the bottom surface of the operating rod 31 to engage with the nut end of the screws 53. Since the length of the connecting rod 41 is greater than the thickness of the ring 23, the connecting rod 4... The upper end of 1 is fixedly connected to a limiting block 44, which allows the sleeve rod 41 to move up and down within the ring 23. This facilitates the engagement of the locking interface on the bottom surface of the operating rod 31 with the nut end of the screw 53. After engagement, with the operating rod 31 as the center point, the robotic arm drives the socket wrench 3 to rotate, thereby removing the screw 53 and realizing the automatic opening of the pressure tank 5. Since the slot on the bottom surface of the positioning seat 2 54 is fitted onto the fixed column 12, it can prevent the center of gravity of the pressure tank 5 from becoming unstable during disassembly, thus avoiding the phenomenon of the pressure tank 5 tipping over.

[0020] The connecting plate 42 has a mounting through hole 43. The operating rod 31 has a circumferentially recessed part 34 in the middle. The mounting through hole 43 is rotatably fitted into the operating rod 31, so that the operating rod 31 can rotate flexibly on the connecting plate 42. This allows for smoother rotation when removing and installing the screw 53. To ensure the stability of the operating rod 31 during rotation, a lubricating oil layer is provided between the mounting through hole 43 and the operating through hole 43 to reduce the friction between them.

[0021] Workflow: During operation, the slot on the bottom surface of the positioning seat 54 is fitted onto the fixed post 12. The robotic arm grips the gripping block 33, causing the locking interface on the bottom surface of the operating rod 31 to engage with the nut end of the screw 53. Since the length of the connecting rod 41 is greater than the thickness of the ring 23, the upper end of the connecting rod 41 is fixedly connected to the limiting block 44, allowing the connecting rod 41 to move up and down within the ring 23. This facilitates the engagement of the locking interface on the bottom surface of the operating rod 31 with the nut end of the screw 53. After engagement, with the operating rod 31 as the center point, the robotic arm drives the socket wrench 3 to rotate, thereby removing the screw 53 and achieving automatic opening of the pressure tank 5. Since the slot on the bottom surface of the positioning seat 54 is fitted onto the fixed post 12, it can prevent the pressure tank 5 from becoming unstable during disassembly, thus avoiding the pressure tank 5 from tipping over.
