Description

Technical Field

[0001] This utility model belongs to the field of spent fuel auxiliary hoisting technology, specifically relating to a spent fuel auxiliary hoisting device. Background Technology

[0002] In the nuclear industry, the safe transportation and handling of spent fuel is a crucial aspect. Spent fuel is typically stored in specialized containers, which are then placed in pools of water for unified storage. To improve storage and processing efficiency, the pools are large, and the spent fuel must be precisely stacked in specific locations within the pools to ensure storage stability. Care must be taken during the hoisting process to prevent damage to the containers and subsequent leaks.

[0003] Existing spent fuel lifting devices have numerous limitations in practical applications. Some devices have a simplistic structural design, resulting in poor flexibility during lifting and difficulty in achieving precise lifting from multiple angles and directions, leading to inefficient lifting tasks under complex conditions. Furthermore, some devices lack stability, easily swaying or shifting during lifting, increasing the risk of spent fuel falling and seriously threatening the safety of operators and the surrounding environment. In addition, existing clamping structures are ineffective at securing spent fuel, lacking an effective adaptive adjustment mechanism, making it difficult to stably clamp spent fuel of different specifications, potentially causing accidents during transportation due to insecure clamping. In view of the aforementioned problems in the existing technology, there is an urgent need to design a new type of spent fuel auxiliary lifting device to improve the flexibility, stability, and safety of lifting operations.

[0005] As a preferred embodiment of the above technical solution, the turntable is fixedly connected to the middle of the crossbeam, and there are two hanging plates and two movable plates, with the two movable plates located on both sides of the turntable.

[0006] As a preferred embodiment of the above technical solution, a top plate is fixedly connected to the turntable, and both ends of the crossbeam are fixedly connected to the top plate by inclined cables.

[0007] As a preferred embodiment of the above technical solution, the rotary drive mechanism includes a first motor, which drives the turntable to rotate through a plurality of first gears, and the turntable is rotatably mounted on the base through bearings.

[0009] As a preferred embodiment of the above technical solution, the rotation drive mechanism includes a third motor, which drives the corresponding take-up reel to rotate.

[0010] The beneficial effects of this utility model are as follows: The spent fuel auxiliary hoisting device of this utility model uses a rotary drive mechanism to drive the turntable to rotate, which, in conjunction with a translation drive mechanism, moves the movable plate. This enables the device to achieve precise hoisting from multiple angles and directions, greatly improving hoisting flexibility and effectively adapting to complex working conditions. The structural design of the turntable connecting the middle of the crossbeam, the installation of inclined cables, and the double movable plate and double hanging plate enhances overall stability and reduces the risk of hoisting sway. The cooperation between the take-up reel and the rotary drive mechanism allows for flexible control of the lifting and lowering of the hanging plate. The electromagnetic actuator controls the extension and retraction of the clamping plate, which can adaptively clamp different specifications of spent fuel, ensuring transportation safety and effectively avoiding accidents caused by insecure clamping. This comprehensively protects the safety and reliability of nuclear facility operation. Attached Figure Description

Slide rails 5 are provided on both sides of the movable groove 4. A movable plate 6 is provided above the movable groove 4. Slider blocks are fixedly connected to both sides of the movable plate 6, and the sliders are slidably mounted on the corresponding slide rails 5. The movable plate 6 is driven to move along the slide rails 5 by a translation drive mechanism. A lifting plate 7 is provided below the movable groove 4. The lifting plate 7 is fixedly connected to... A cable 8 and several lifting ropes 9 are connected to a movable plate 6. Several take-up reels 10 are installed on the movable plate 6. The cable 8 and lifting ropes 9 correspond to and are fixedly connected to the corresponding take-up reels 10. The take-up reels 10 are driven to rotate by a rotary drive mechanism. The lower surface of the suspended plate 7 is provided with a clamping groove 11. Several mounting grooves 12 are provided around the clamping groove 11. Clamping plates 13 are respectively provided in the mounting grooves 12. The clamping plates 13 are controlled by electromagnetic actuators 16 to extend or retract from the mounting grooves 12.

The take-up reels 10 rotate synchronously to release the line, causing the suspended plate 7 to descend. The suspended plate 7 lands on the special container containing spent fuel, so that the upper end of the special container fits into the clamping groove 11. The electromagnetic actuators 16 control the clamping plates 13 to extend out of the mounting grooves 12 and clamp the upper end of the special container. The upper part of the dedicated container is generally pre-drilled with several lifting holes for hoisting. Corresponding pins can be inserted into these holes when the clamping plate 13 clamps the dedicated container, further improving the safety of the spent fuel hoisting process.

For large-capacity water tanks, the base 1 can also be fixed in the middle of the water tank.

[0018] Furthermore, the turntable 2 is fixedly connected to the middle of the crossbeam 3, with two hanging plates 7 and two movable plates 6, located on opposite sides of the turntable 2. This allows the turntable 2 to be positioned in the middle of the water tank, enabling simultaneous operation at two workstations by rotating the crossbeam 3, thus improving the efficiency of spent fuel hoisting.

[0019] Furthermore, a top plate 14 is fixedly connected to the turntable 2, and both ends of the crossbeam 3 are fixedly connected to the top plate 14 via inclined cables 15. The inclined cables 15 improve the load-bearing capacity of the crossbeam 3.
