Description

Technical Field

[0001] This invention belongs to the field of support and hanger technology, specifically a high-safety support and hanger structure for nuclear power plants. Background Technology

[0002] Pipe supports are mainly used in power plant steam and water pipelines or boiler equipment, and on equipment devices that experience thermal displacement during operation. The working and thermal displacement requirements of spring supports are calculated based on the stress conditions of the pipeline. Pipe supports can be mainly divided into four categories: spring supports, pipe supports, root supports, and accessory supports.

[0003] Pipe supports are widely used in various industries, and they also play a role in the installation and fixation of pipelines in nuclear power engineering. However, the current pipe supports are fixed to the top of the building, which cannot be effectively adjusted for lifting during pipeline installation. This means that the installation of pipelines requires manual climbing and equipment assistance to install and fix the pipelines on the supports on the building top, which is quite inconvenient. Therefore, in view of the current situation, it is necessary to improve them. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a high-safety support structure for nuclear power plants, which effectively solves the problem that the current support structure cannot operate the pipeline installation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-safety support structure for nuclear power plants, comprising a mounting plate, a connecting plate fixedly connected to the bottom of the mounting plate, sliding grooves on the upper parts of both sides of the connecting plate, a co-directional moving component installed between the interior of the two sliding grooves, two pairs of folding telescopic arms symmetrically installed in the middle of the bottom plate of the connecting plate, the two sides of the co-directional moving component being connected to the upper parts of the two pairs of folding telescopic arms via a first connecting rod, a bearing seat installed between the bottom of the two pairs of folding telescopic arms, a pipe placement seat fixedly connected to the top of the bearing seat, two fixing straps on the top of the bearing seat, adjusting components installed at both ends of the bearing seat, the adjusting components being connected between the ends of the fixing straps and the bottom of the folding telescopic arms, T-shaped grooves on both sides of the top of the connecting plate, a linkage clamping component installed between the two T-shaped grooves, a second connecting rod rotatably connected to both sides of the linkage clamping component, a push seat rotatably connected between the ends of the four second connecting rods, a pipe clamping seat fixedly connected to the bottom of the push seat, the pipe clamping seat being located directly above the pipe placement seat.

[0006] Preferably, the unidirectional moving component includes a first bidirectional threaded shaft, two moving plates, and a transmission gear.

A motor is installed at one end of the connecting plate, and the output end of the motor is fixedly connected to one end of the first bidirectional threaded shaft. The other end of the first bidirectional threaded shaft extends to the other end of the connecting plate. The transmission gear is fixedly connected to the other end of the first bidirectional threaded shaft, thereby enabling effective horizontal movement adjustment.

[0007] Preferably, each pair of folding telescopic arms includes a fixed block, a rotating arm one, and a rotating arm two. The fixed block is fixedly connected to the bottom of the connecting plate, the rotating arm one is rotatably connected to one side of the fixed block, and the rotating arm two is movably connected to the bottom of the rotating arm one. The bottom of each rotating arm two is fixedly connected with a connecting pin, and the bottom of the four first connecting rods is rotatably connected to the middle of the four rotating arms one, thereby enabling effective adjustment.

A connecting block is movably connected between the same end of the two connecting shafts. Folding adjustment gears are fixedly connected to both sides of the two connecting shafts. The two folding adjustment gears on the same side of the two connecting shafts are meshed together, so that the folding telescopic arm can effectively perform folding and extension operations.

[0009] Preferably, the adjusting component includes four inverted T-shaped slide grooves symmetrically opened at both ends of the bearing seat, four connecting pins rotatably connected inside the four inverted T-shaped slide grooves, a fixed gear fixedly connected to one side of each connecting pin, a rotating gear meshing with the fixed gear rotatably connected inside each of the four inverted T-shaped slide grooves, and a sliding strip slidably installed inside each inverted T-shaped slide groove, with a rack fixedly connected to one side of the sliding strip meshing with the rotating gear, thereby enabling effective transmission.

[0010] Preferably, each of the sliding strips has a hanging ring fixedly connected to its top, and each of the two fixing straps includes a tightening strap and two hooks. The two hooks are connected to both ends of the tightening strap, and the hooks are hooked to the hanging rings, thereby effectively tightening and fixing the pipes placed on the pipe placement seat.

[0011] Preferably, the linkage clamping component includes a second bidirectional threaded shaft, which is rotatably connected between the middle of the two T-slots.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example 1, by Figures 1 to 6The present invention includes a mounting plate 1, a connecting plate 2 fixedly connected to the bottom of the mounting plate 1, sliding grooves 3 on the upper parts of both sides of the connecting plate 2, and a unidirectional moving component 4 installed between the interior of the two sliding grooves 3. Two pairs of folding telescopic arms 5 are symmetrically installed in the middle of the bottom plate of the connecting plate 2. The two sides of the unidirectional moving component 4 are connected to the upper parts of the two pairs of folding telescopic arms 5 through a first connecting rod 6. A bearing seat 7 is installed between the bottom of the two pairs of folding telescopic arms 5. A pipe placement seat 8 is fixedly connected to the top of the bearing seat 7. Two fixing straps 9 are provided on the top of the bearing seat 7. Adjusting components 10 are installed at both ends of the bearing seat 7 and are connected to the ends of the fixing straps 9. Between the bottom of the connecting plate 2 and the bottom of the folding telescopic arm 5, T-shaped grooves 11 are provided on both sides of the top of the connecting plate 2. A linkage clamping component 12 is installed between the two T-shaped grooves 11. A second connecting rod 13 is rotatably connected to both sides of the linkage clamping component 12. A push seat 14 is rotatably connected between the ends of the four second connecting rods 13. A pipe clamping seat 15 is fixedly connected to the bottom of the push seat 14. The pipe clamping seat 15 is located directly above the pipe placement seat 8. Arc-shaped pipe grooves are provided at equal intervals on the top of the pipe placement seat 8 and the bottom of the pipe clamping seat 15. Rubber pads are installed inside the arc-shaped pipe grooves, which can effectively clamp and fix the pipe, ensuring the stability of the pipe installation.

[0027] In Embodiment 2, based on Embodiment 1, the unidirectional moving component 4 includes a first bidirectional threaded shaft 16, two moving plates 17, and a transmission gear 19. The first bidirectional threaded shaft 16 is rotatably connected between the middle of the two sliding slots 3. The two moving plates 17 are threaded to both sides of the first bidirectional threaded shaft 16 and slidably installed inside the two sliding slots 3 respectively. The first connecting rod 6 is rotatably connected to both ends of the two moving plates 17. A motor 18 is installed at one end of the connecting plate 2. The output end of the motor 18 is fixedly connected to one end of the first bidirectional threaded shaft 16. The other end of the first bidirectional threaded shaft 16 extends to the other end of the connecting plate 2. The transmission gear 19 is fixedly connected to the other end of the first bidirectional threaded shaft 16. The first bidirectional threaded shaft 16 is a large-pitch threaded shaft, thereby enabling effective horizontal movement adjustment. Both pairs of folding telescopic arms 5 include a fixing block 20 and a rotating... Arm 1 21 and rotating arm 23 are fixedly connected to the bottom of the connecting plate 2 by a fixed block 20. Rotating arm 1 21 is rotatably connected to one side of the fixed block 20, and rotating arm 23 is movably connected to the bottom of rotating arm 1 21. Connecting pins 24 are fixedly connected to the bottom of rotating arm 23. The bottoms of the four first connecting rods 6 are rotatably connected to the middle of the four rotating arms 1 21, thereby enabling effective adjustment. Connecting fixed shafts are fixedly connected between the bottoms of the two rotating arms 1 21 and the tops of the two rotating arms 23 on the same side of the bottom of the connecting plate 2. Connecting blocks are movably connected between the same ends of the two connecting fixed shafts. Folding adjusting gears are fixedly connected to both sides of the two connecting fixed shafts. The two folding adjusting gears on the same side of the two connecting fixed shafts mesh with each other, thereby enabling the folding telescopic arm 5 to effectively fold and extend.

[0028] When it is necessary to adjust the folding of the two pairs of folding telescopic arms 5, the motor 18 is started to rotate the first bidirectional threaded shaft 16. The rotation of the first bidirectional threaded shaft 16 will cause the two moving plates 17 to move in opposite directions inside the two sliding through slots 3. The two moving plates 17 moving in opposite directions will drive the first connecting rods 6 at both ends to move. The movement of the first connecting rods 6 will pull the rotating arm rod 1 21 to rotate upward. The rotation and upward movement of the rotating arm rod 1 21 will drive the rotating arm rod 23 to rotate and fold upward through the connecting fixed shaft and folding adjustment teeth on it, as well as the connecting fixed shaft and folding adjustment teeth on the rotating arm rod 23. This will enable the folding telescopic arms 5 to effectively retract, fold, and lift.

[0029] In Example 3, based on Example 2, the adjusting component 10 includes four inverted T-shaped grooves 25 symmetrically opened at both ends of the bearing seat 7. Four connecting pins 24 are rotatably connected to the inside of the four inverted T-shaped grooves 25. A fixed gear 26 is fixedly connected to one side of each connecting pin 24. A rotating gear 27 that meshes with the fixed gear 26 is rotatably connected to the inside of each of the four inverted T-shaped grooves 25. A sliding strip 28 is slidably installed inside each of the inverted T-shaped grooves 25. A rack 29 that meshes with the rotating gear 27 is fixedly connected to one side of each sliding strip 28, thereby enabling effective transmission. A hanging ring 30 is fixedly connected to the top of each sliding strip 28. Each of the two fixing straps 9 includes a tightening strap 31 and two hooks 32. The two hooks 32 are connected to both ends of the tightening strap 31, and the hooks 32 are hooked to the hanging rings 30, thereby effectively tightening and fixing the pipe placed on the pipe placement seat 8.

[0030] When the rotating arm 23 rotates and folds upward, it drives the bearing seat 7 and the pipe placement seat 8 to move upward through the four connecting pins 24, so that the pipe placement seat 8 lifts the pipe to the top of the building. The rotation of the rotating arm 23 drives the connecting pins 24 and the fixed gear 26 to rotate. The rotation of the fixed gear 26 drives the rotating gear 27 to rotate. The rotation of the rotating gear 27 drives the rack 29 to move downward. The downward movement of the rack 29 drives the sliding bar 28 to move downward. The downward movement of the sliding bar 28 drives the hanging ring 30 to move downward. The downward movement of the hanging ring 30 pulls the tightening strap 31 downward through the hook 32, so that the tightening strap 31 tightens and fixes the pipe surface on the pipe placement seat 8, thereby ensuring the stability of the pipe lifting and moving upward.

[0031] In Example 4, based on Example 2, the linkage clamping component 12 includes a second bidirectional threaded shaft 33. The second bidirectional threaded shaft 33 is a small-pitch threaded shaft. The second bidirectional threaded shaft 33 is rotatably connected between the middle of the two T-slots 11. One end of the second bidirectional threaded shaft 33 extends to the other end of the connecting plate 2 and is fixedly connected to a second transmission gear 34. The second transmission gear 34 meshes with a first transmission gear 19. The surfaces of the second bidirectional threaded shaft 33 located inside the two T-slots 11 are threadedly connected to moving strips 35. U-shaped blocks 36 are fixedly connected to the opposite sides of the two moving strips 35. One end of the second connecting rod 13 is rotatably connected to the middle of the U-shaped block 36, thereby effectively pushing the push seat 14 and the pipe clamping seat 15 downward.

[0032] When the first bidirectional threaded shaft 16 rotates, it drives the second bidirectional threaded shaft 33 to rotate through the transmission gear 19 and the transmission gear 2 34. The rotation of the second bidirectional threaded shaft 33 causes the two moving bars 35 on both sides to move relative to each other. The two moving bars 35 push the second connecting rod 13 to move, so that the four second connecting rods 13 push the push seat 14 and the pipe clamping seat 15 to move down, and finally make the pipe clamping seat 15 cooperate with the pipe placement seat 8 to clamp and fix the pipe.

[0033] The second bidirectional threaded shaft 33 has a moving strip 37 threadedly connected to the surface inside the two T-shaped grooves 11. The bottom of the moving strip 37 is fixedly connected to three vertical rods 38. The bottom of the vertical rods 38 is fixedly connected to a contact block 39. An arc groove 40 is opened on one side of the contact block 39, which can effectively support the folding telescopic arm 5 and ensure the stability of the folding telescopic arm 5 when it is retracted and folded.

[0034] When the rotating arm 1 21 and the two rotating arms 23 fold and retract upwards, they will cause the connecting fixed shafts on the rotating arm 1 21 and the two rotating arms 23 to move upwards. The rotation of the second bidirectional threaded shaft 33 will cause the two moving strips 2 37 on its surface to move relative to each other. The movement of the moving strips 2 37 will cause the vertical rod 38 and the abutment block 39 to move, and finally the arc groove 40 on the abutment block 39 will contact the connecting fixed shaft on the rotating arm 2 23. The arc groove 40 can effectively support the connecting fixed shaft, thereby ensuring the stability and safety of the folding telescopic arm 5 during folding and retraction.

[0035] This support structure features a lifting and adjustment function, allowing for convenient pipe installation by lowering the support, thus reducing the difficulty of pipe installation. Furthermore, the structure incorporates a double fixing structure, which sequentially secures the installed pipe during the support's ascent, effectively ensuring the stability of the pipe installation. The fixing structure also includes an auxiliary lifting and fixing structure, ensuring the safety of pipe lifting. Therefore, the high safety and convenience of this support structure meet the usage requirements of nuclear power plant pipeline installation. Moreover, this support structure is easy to use and operate, stable and reliable, and its performance meets the high safety requirements of nuclear power plants.
