Description

Technical Field

[0001] This utility model relates to the field of nuclear reactor technology, specifically to a nuclear reactor operating platform. Background Technology

[0002] A nuclear reactor, also known as an atomic reactor or simply a reactor, is a device capable of sustaining a controlled, self-sustaining chain reaction of nuclear fission to realize the utilization of nuclear energy. Through the proper arrangement of nuclear fuel, a nuclear reactor can achieve a self-sustaining chain reaction of nuclear fission without the need for additional neutron sources. Strictly speaking, the term "reactor" should encompass fission reactors, fusion reactors, and hybrid fission-fusion reactors, but generally refers only to fission reactors. Secondary dismantling of a nuclear reactor mainly refers to the technical operations of further dismantling and removing the reactor core or molten material after a nuclear facility has been decommissioned or an accident has occurred.

[0003] During the secondary dismantling of a nuclear reactor, a nuclear reactor work platform is required. However, existing work platforms require the clamps on the components to be dismantled to be constantly changed according to the shape of the components, resulting in repetitive operations that consume significant time and reduce the efficiency of secondary dismantling. To address these technical issues, we have designed a new nuclear reactor work platform. Utility Model Content

[0004] The purpose of this invention is to provide a nuclear reactor working platform that has the advantage of not requiring frequent clamp changes. This solves the problem that existing nuclear reactor working platforms require constant clamp changes based on the shape of the components to be dismantled, which consumes a lot of time and reduces the efficiency of secondary dismantling of nuclear reactors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nuclear reactor operating platform, including a frame, with a corridor connected to the outside of the frame, X-beams connected to both sides of the top of the frame, and Y-beams connected to opposite ends of the two X-beams, a load-bearing platform installed at the center of the top of the frame, the load-bearing platform including a platform body, the bottom of the platform body being connected to the center of the top of the frame, and a moving slot being provided through the center of both ends and the center of both sides of the top of the platform body, and a drive motor being installed through the center of both ends and the center of both sides of the outside of the platform body, the output end of the drive motor being connected to a coupling, and a drive screw being connected to the side of the coupling away from the drive motor.

[0006] Preferably, the drive screw is fitted with a support sleeve via bearings on both the side near the middle of the platform and the side near the coupling, with the top of the support sleeve connected to the bottom of the platform.

[0007] Preferably, the drive screw is threaded with a movable plate, the top of the movable plate passes through a movable groove and is connected to a support plate, and both sides of the bottom of the support plate are connected to sliders. The inner wall of the slider is slidably provided with a slide rail, and the bottom of the slide rail is connected to the top of the platform.

[0008] Preferably, both ends of the slide rail are connected to support seats, the bottom of the support seats is connected to the top of the platform, and a buffer block is connected to the opposite side of the two support seats.

[0009] Preferably, the top of the support plate is connected to a flexible clamp, and several grooves are opened through both sides of the top of the platform.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention, through the use of a support platform, has the advantage of eliminating the need for frequent clamp replacements. The component to be disassembled is transferred to the top of the platform, and the peripheral control terminal of the nuclear reactor work platform controls the operation of four drive motors, causing four drive screws to rotate and drive four moving plates to move towards the center of the platform. Finally, the four flexible clamps complete the clamping of the component to be disassembled. The flexible clamps can quickly adapt to workpieces of different shapes and sizes, eliminating the need for frequent replacement of special clamps and improving work efficiency.

[0018] Please see Figures 1-5A nuclear reactor working platform includes a frame 1, with a corridor 2 connected to the outside of the frame 1. X-beams 3 are connected to both sides of the top of the frame 1, and Y-beams 4 are connected to the opposite ends of the two X-beams 3. A load-bearing platform 5 is installed at the center of the top of the frame 1. The load-bearing platform 5 includes a platform body 51. The bottom of the platform body 51 is connected to the center of the top of the frame 1. Moving slots 514 are opened through the center of both ends and the center of both sides of the top of the platform body 51. Drive motors 56 are installed through the center of both ends and the center of both sides of the platform body 51. A coupling 55 is connected to the output end of the drive motor 56. A drive screw 510 is connected to the side of the coupling 55 away from the drive motor 56.

[0019] The frame 1 is welded from 100×200×t5 rectangular tubes, and its upper surface is fitted with a 20mm thick aluminum plate. It is connected to the support platform 5 on the top. The dimensions of the frame 1 are 4530×3590×845mm.

[0020] The support platform 5 is mainly used to support the components to be dismantled and can smoothly discharge the wastewater generated during cutting. Therefore, the support platform 5 has a hollow shape. At the same time, in order to facilitate the subsequent wire saw to completely penetrate the biological shielding block, the upper side of the support platform 5 is rectangular and protrudes, forming multiple grooves 512 for the wire saw to pass through; the dimensions are approximately 2600×2600×195mm.

[0021] The use of corridor 2 facilitates equipment installation, maintenance, and repair. It is mainly constructed of 30-angle steel and anti-slip galvanized sheet welded together. The handrail is made of 33.5×1.5mm steel pipe welded together. It consists of 4 components with dimensions of 4400×500×868mm (2 pieces), 4500×500×868mm (1 piece), and 4000×500×868mm (1 piece).

[0022] X-beam 3 is mainly composed of 100×200mm aluminum profiles and covered with 20mm thick aluminum plates. Its main function is to serve as a load-bearing mechanism for diamond wire saws and plasma cutters to move in the X direction. Therefore, a drive component is installed on it.

[0023] Y-beam 4, consisting of a 100×200mm aluminum profile as its main body and covered with a 20mm thick aluminum plate, primarily serves as a load-bearing mechanism for the movement of diamond wire saws and plasma cutters in the Y direction. Therefore, a drive mechanism is also installed on it.

[0024] The drive screw 510 has a support sleeve 511 mounted on the side near the middle of the platform 51 and the side near the coupling 55 via bearings. The top of the support sleeve 511 is connected to the bottom of the platform 51. The two support sleeves 511 can support the drive screw 510 and facilitate its rotation.

[0025] The drive screw 510 is threaded with a movable plate 57. The top of the movable plate 57 passes through the movable groove 514 and is connected to a support plate 513. Slider 58 is connected to both sides of the bottom of the support plate 513. A slide rail 59 is slidably provided through the inner wall of the slider 58. The bottom of the slide rail 59 is connected to the top of the platform 51. The movable plate 57 can be moved easily through the movable groove 514.

[0026] Both ends of the slide rail 59 are connected to support seats 52. The bottom of the support seats 52 is connected to the top of the platform 51. Buffer blocks 53 are connected to the opposite sides of the two support seats 52. The buffer blocks 53 can buffer and protect the support plate 513. The two support seats 52 can support and position the slide rail 59, improving the stability of the slide rail 59.

[0027] The top of the support plate 513 is connected to a flexible clamp 54, and several grooves 512 are opened through both sides of the top of the platform 51. The grooves 512 facilitate the passage of external wire saws. The flexible clamp 54 can quickly adapt to workpieces of different shapes and sizes without the need for frequent replacement of special clamps.

[0028] In use, the component to be disassembled is transferred to the top of the platform 51. The four drive motors 56 are controlled by the peripheral control terminal of the nuclear reactor work platform, which causes the four drive screws 510 to rotate and drive the four moving plates 57 to move towards the center of the platform 51. Finally, the four flexible clamps 54 complete the clamping of the component to be disassembled. The flexible clamps 54 can quickly adapt to workpieces of different shapes and sizes, eliminating the need for frequent replacement of special clamps and improving work efficiency.

[0029] In summary, this nuclear reactor work platform, through the use of the load-bearing platform 5, solves the problem that existing nuclear reactor work platforms require the clamps to be constantly changed according to the shape of the components to be dismantled when holding them. This repeated operation consumes a lot of time and reduces the efficiency of secondary dismantling of nuclear reactors.
