Description

Technical Field

[0001] The utility model relates to the technical field of assembling ring hanger beams of AP reactor type nuclear power plants, in particular to an auxiliary tooling for assembling ring hanger beams and containment shells of AP reactor type nuclear power plants. Background Art

[0002] The ring beam is the supporting box girder for the track of the nuclear island ring crane ("ring crane" for short). Ring beams are constructed using modular construction. They are prefabricated and assembled into individual modules in-plant, then transported to the assembly site. They are then hoisted in sections to the inner wall of the containment vessel. The containment vessel has a circumference of 135,000 mm. The arc of contact between a single ring beam segment and the inner wall of the vessel is approximately 11,250 mm. The ring beam is assembled from 12 sections. The modular structure of the ring beam is complex, with each section primarily consisting of an upper plate, a lower plate, radial stiffeners, webs, rings, a horizontal rail base plate, a seismic base plate, and reinforcement plates. A single ring beam section has an overall height of 2,800 mm, a width of 1,300 mm, and weighs approximately 30 tons. The large dimensions and weight of each ring beam segment necessitate high assembly precision, making welding distortion and overall dimensional control challenging. Furthermore, maintaining the levelness of the upper plate during assembly is challenging.

[0003] Traditional nuclear power plant ring beams are assembled using single-plate installation. This has long construction times, requires extensive on-site welding, and has numerous disadvantages, such as cross-construction of the nuclear island. Therefore, a new method has been adopted, where the entire section is assembled on-site after being assembled into a single piece.

[0004] However, the way the whole section is assembled on site after forming is difficult to control the gap between the ring beam and the cylinder, and the horizontality of the ring beam is difficult to control. As a result, the horizontality of the upper surface of the ring beam after assembly does not meet the technical requirements, but cannot meet the basic conditions for the installation and operation of the ring crane.

[0043] The present invention will be further described in detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0044] The specific structure is as Figures 1 to 5 shown.

[0045] This embodiment provides an auxiliary tooling for assembling the ring beam and the containment shell of an AP reactor type nuclear power plant. The ring beam 8 is arranged on the inner side of the containment shell 7. The auxiliary tooling includes: an L-shaped horse plate 1, a jack 3 and a fixed block 4; the fixed block 4 is used to be fixed on the upper surface of the ring beam 8, the L-shaped horse plate 1 has a first section and a second section that are perpendicular to each other, the first section is located above the fixed block 4, and the end is used to be connected to the inner wall of the containment shell 7, and an installation space is formed between the second section and the fixed block 4; the jack 3 is arranged in the installation space, and one end is connected to the second section, and the other end is connected to the fixed block 4.

[0046] In this embodiment, when in use, the fixed block 4 is welded to the upper surface of the ring beam 8, the end of the first section of the L-shaped horse plate 1 is welded to the inner wall of the containment shell 7, the jack 3 is installed in the installation space and the two ends are respectively connected to the second section of the L-shaped horse plate 1 and the fixed block 4. Since the length of the L-shaped horse plate 1 remains unchanged, the gap between the ring beam 8 and the containment shell 7 decreases as the jack 3 is lifted, so that the gap between the ring beam 8 and the containment shell 7 and the levelness of the ring beam 8 can be effectively adjusted to a state that meets the technical requirements, ensuring that the levelness of the upper surface of the ring beam 8 meets the technical requirements after assembly is completed, and meeting the basic conditions for the installation and operation of the ring crane.

[0047] An optional technical solution of this embodiment further includes a reinforcement device 6, which is disposed on the fixing block 4 and is used to fix the first section. After the gap between the ring beam 8 and the containment shell 7 and the levelness of the ring beam 8 are adjusted to meet technical requirements, the first section of the L-shaped saddle plate 1 is fixed by the reinforcement device 6, thereby fixing the position of the L-shaped saddle plate 1. When the weld seam between the ring beam 8 and the containment shell 7 is welded, the effect of welding shrinkage on the levelness of the upper surface of the ring beam 8 is reduced.

[0048] The reinforcing device 6 may be a bolt that secures the first section of the L-shaped saddle 1 to the fixing block 4. In this case, the thickness of the first section of the L-shaped saddle 1 needs to be greater than the diameter of the bolt. However, this embodiment is not limited thereto, and the reinforcing device 6 may also be other existing structures that can secure the first section of the L-shaped saddle 1.

[0049] In the optional technical solution of this embodiment, the reinforcement device 6 includes a clamping assembly and a driving assembly; the clamping assembly has a clamping space, and the first section is arranged in the clamping space; the driving assembly is used to drive the clamping assembly to clamp the first section in the clamping space.

[0050] In this embodiment, when in use, the first section of the L-shaped horse plate 1 is passed through the clamping space, and then the end of the first section of the L-shaped horse plate 1 is welded to the inner wall of the containment shell 7. After the gap between the ring beam 8 and the containment shell 7 and the horizontality of the ring beam 8 are adjusted to a state that meets the technical requirements, the clamping assembly is driven by the driving assembly to clamp the first section, and the fixation is stable and convenient.

[0051] In the optional technical solution of this embodiment, the clamping assembly includes a bottom plate 64, a fixed plate 61, a movable plate 65 and a top plate 62; the bottom plate 64 and the top plate 62 are arranged opposite each other, and the bottom plate 64 is arranged on the top of the fixed block 4; the fixed plate 61 and the movable plate 65 are arranged opposite each other and are both located between the bottom plate 64 and the top plate 62, the lower end of the fixed plate 61 is connected to the bottom plate 64, and the upper end of the fixed plate 61 is connected to the top plate 62; a guide portion is provided on the upper side of the bottom plate 64 and / or a guide portion is provided on the lower side of the top plate 62, and the movable plate 65 is slidably connected to the guide portion; a clamping space is formed between the fixed plate 61 and the movable plate 65, and the driving assembly is used to drive the movable plate 65 to move along the guide portion toward or away from the fixed plate 61. The guide portion can be a guide groove, a guide rib, or a guide rail.

[0052] In this embodiment, when in use, the first section of the L-shaped horse plate 1 is passed between the fixed plate 61 and the movable plate 65, and then the driving assembly drives the movable plate 65 to move along the guide portion toward the fixed plate 61, so that the movable plate 65 and the fixed plate 61 are in close contact with the first section of the L-shaped horse plate 1, thereby completing the clamping and fixing function. The clamping assembly has a simple structure and a good clamping effect.

[0053] In this embodiment, the driving component can be a telescopic motor or a push-pull rod, as long as it can drive the movable plate 65 to move stably.

[0054] In this embodiment, the drive assembly preferably includes a screw 63 and a rotating handle 10; the screw 63 is provided through the fixed plate 61 and the movable plate 65, and the screw 63 can drive the movable plate 65 to move along the guide portion toward or away from the fixed plate 61 by rotating; the rotating handle 10 is transmission-connected to one end of the screw 63, and the rotating handle 10 is used to drive the screw 63 to rotate. The screw 63 is rotated by rotating the rotating handle 10. Since the screw 63 is provided through the movable plate 65 and is threadedly engaged with the movable plate 65, the rotation of the screw 63 can drive the movable plate 65 to move, and the movement position is stable, ensuring the clamping effect. It should be noted that when the screw 63 rotates, the fixed plate 61 remains fixed.

[0055] Furthermore, the drive assembly further includes an eccentric wheel 9, a driven wheel 11, and a transmission chain 12. The eccentric wheel 9 is mounted on the fixed plate 61, and the driven wheel 11 is mounted on the screw 63. The eccentric wheel 9 and the driven wheel 11 are connected by the transmission chain 12. The rotating handle 10 is mounted on the eccentric wheel 9. By rotating the handle 10, the eccentric wheel 9 is rotated, and the eccentric wheel 9 drives the driven wheel 11 to rotate via the transmission chain 12, thereby driving the screw 63 to rotate. The structure is simple, and the drive is stable and convenient.

[0056] In an optional technical solution of this embodiment, the clamping assembly further includes a guide rod, which is provided through the fixed plate 61 and the movable plate 65, and the guide rod and the guide portion have the same guiding direction. The driving assembly is used to drive the movable plate 65 to move toward or away from the fixed plate 61 along the guide rod and the guide portion. The guiding effect of the guide rod ensures the stability of the movement of the movable plate 65.

[0057] In an optional technical solution of this embodiment, a plurality of L-shaped horse plates 1 are arranged at intervals. The plurality of horse plates simultaneously adjust the gap between the ring beam 8 and the containment shell 7 and the horizontality of the ring beam 8, and the adjustment is highly stable.

[0058] An optional technical solution of this embodiment also includes a reinforcing rib plate 2, through which all L-shaped horse panels 1 are connected. This ensures that all L-shaped horse panels 1 are subjected to force simultaneously, thereby improving stability and reliability during adjustment. Multiple reinforcing rib plates 2 can be provided to improve the stability of the connection.

[0059] An optional technical solution of this embodiment further includes a reinforcement block 5, which is used to be fixed to the upper surface of the ring beam 8. The reinforcement block 5 is connected to the fixing block 4 and is located on the side of the fixing block 4 facing away from the jack 3. The reinforcement block 5 and the fixing block 4 are subjected to force together to ensure stability and reliability.

[0060] Specifically, taking the arrangement of two L-shaped horse plates 1 as an example, one end of the two L-shaped horse plates 1 is fixedly welded to the inner wall of the containment shell 7, the reinforcing rib plate 2 is fixedly welded to the outside of the two L-shaped horse plates 1, the fixing block 4 is fixedly installed below the middle of the two L-shaped horse plates 1, the jack 3 is movably installed between one end of the fixing block 4 and the two L-shaped horse plates 1, and the other end of the fixing block 4 is fixedly installed with a reinforcing block 5.

[0061] Among them, the bottom plate 64 is movably installed on the top of the fixed block 4 and close to one end of the reinforcement block 5. Two slide rails 66 are provided on the top of the bottom plate 64. One end of the top of the two slide rails 66 is fixedly installed with a fixed plate 61, and a top plate 62 is fixedly installed on the top of the two fixed plates 61. The inside of the other end of the two slide rails 66 is movably installed with a movable plate 65. When in use, the two L-shaped horse plates 1 are respectively passed through the corresponding two movable plates 65 and the two fixed plates 61, and then the movable plate 65 is moved along the slide rail 66 on the bottom plate 64, so that the movable plate 65 and the fixed plate 61 are tightly attached to the L-shaped horse plate 1, thereby completing the clamping and fixing function. When welding is performed, it is positioned by the reinforcement device 6 provided on the top of the fixed block 4, so that when the ring beam 8 and the containment shell 7 are welded, the influence of shrinkage on the horizontality of the upper surface of the ring beam 8 is reduced.

[0062] Among them, the L-shaped horse plate 1 is cut from the L-shaped steel plate, and the reinforcing rib plate 2 is cut from the long steel plate. By cutting the L-shaped horse plate 1 from the L-shaped steel plate and the reinforcing rib plate 2 from the long steel plate, the strength of the structure is also guaranteed.

[0063] Among them, the jack 3 is a jacking device, which is used to adjust the gap between the ring beam 8 and the containment shell 7 and the horizontality of the ring beam 8. By setting the jack 3 as a jacking device and using the jack 3 to adjust the gap between the ring beam 8 and the containment shell 7 and the horizontality of the ring beam 8, it is convenient to use.

[0064] Among them, the fixed block 4 and the reinforcing block 5 are connected by welding, and the fixed block 4 and the reinforcing block 5 are a joint force-bearing device. By connecting the fixed block 4 and the reinforcing block 5 by welding, the fixed block 4 and the reinforcing block 5 are made into a joint force-bearing device, so that when subjected to force, they are subjected to force together.

[0065] Among them, a screw 63 is movably installed on the upper ends of the two movable plates 65 and the two fixed plates 61, and a guide rod is movably installed on the lower ends of the two movable plates 65 and the two fixed plates 61. One end of the screw 63 is connected to the driven wheel 11, and the internal transmission of the lower end of the transmission chain 12 is connected to the eccentric wheel 9. A rotating handle 10 is fixedly installed on the surface of the eccentric wheel 9. When the movable plate 65 is moved, the rotating handle 10 is rotated, so that the eccentric wheel 9 drives the driven wheel 11 to rotate through the transmission chain 12, and since the driven wheel 11 and the screw 63 are driven to rotate, the movable plate 65 is indirectly moved, thereby realizing the clamping movement.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
