Description

An explosion-proof pipe support assembly for power plants with emergency pressure relief function Technical Field

[0001] This utility model belongs to the field of pipeline support technology, specifically a power plant explosion-proof pipeline support assembly with emergency pressure relief function. Background Technology

[0002] Pipe supports are structural components used to support overhead pipelines. Their main function is to support and fix the pipeline, ensuring the stability and safe operation of the pipeline system. They can withstand the weight and pressure of the pipeline, control its displacement and deformation, and transfer the internal pressure, external loads, and elastic forces generated by temperature deformation from the pipeline to the building structure. Pipe supports come in various types, such as fixed supports, sliding supports, guide supports, and rolling supports, selected according to the pipeline's operating performance and layout requirements. Their applications are wide-ranging, covering multiple fields including construction, industrial, and civil engineering. In industries such as petrochemicals, power, and pharmaceuticals, pipe supports are crucial for ensuring the normal operation and safety of pipeline systems.

[0003] Existing pipe supports and pipes are usually rigidly connected. Rigid connections have poor protection capabilities and do not have effective explosion resistance. When the supports are subjected to external explosive impacts, it can easily lead to damage to both the supports and the pipes, reducing their service life. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a power plant explosion-proof pipe support assembly with emergency pressure relief function, which effectively solves the problem that the existing pipe supports and pipes are usually rigidly connected, which does not have an effective explosion-proof effect, and the supports and pipes are easily damaged when subjected to external explosive impact.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power plant explosion-proof pipe support assembly with emergency pressure relief function, comprising a support frame, with support rods fixedly installed at both ends of the top of the support frame, a lower clamp fixedly installed in the middle of the top of the support frame, an upper clamp provided above the lower clamp, soft pads fixedly installed on both sides of the inner walls of the upper and lower clamps, and air cushions fixedly installed in the middle of the inner walls of the upper and lower clamps, and a servo motor fixedly installed on one side of the top of the support frame via a support plate, the output end of the servo motor being provided with a transmission component. An airbag is fixedly installed at the bottom inside the support frame. A first air tube is fixedly installed at the middle of the top of the airbag through an air nozzle. The top of the first air tube passes through the lower clamp and connects to the air cushion. A second air tube is fixedly installed at one end of the airbag through an air nozzle. The upper end of the second air tube passes through the upper clamp and connects to the air cushion. Pressure plates are provided on both sides inside the support frame. The transmission component is connected to the upper clamp and the two pressure plates. When the servo motor is running, it outputs power to the upper clamp through the transmission component, causing the upper clamp to move down to press the pipe and causing the two pressure plates to move down to squeeze the airbag.

[0006] Preferably, the transmission assembly includes a driving bevel gear, which is fixedly installed at the output end of the servo motor. A driven bevel gear is meshed with one side of the surface of the driving bevel gear, and a shaft is fixedly installed in the middle of the driven bevel gear. The surface of the shaft is rotatably connected to the top of the support frame through four bearings.

[0007] Preferably, a first bevel gear is fixedly installed at both ends of the shaft, a second bevel gear is meshed with the lower part of the surface of the first bevel gear, a rotating shaft is fixedly installed in the middle of the second bevel gear, the bottom of the rotating shaft is rotatably connected to the top of the support frame, a driving gear is fixedly installed on the top of the rotating shaft, a positioning frame is rotatably installed on the top of the driving gear, and the bottom of the two positioning frames is fixedly connected to the top of the support frame.

[0008] Preferably, each of the driving gears is meshed with a driven gear on one side, and each driven gear has a threaded sleeve fixedly installed inside. Each of the two threaded sleeves has a bushing rotatably installed in the middle of its surface, and each bushing is fixedly connected to the top of the support frame. Each of the threaded sleeves has a threaded rod threadedly connected inside, and the bottom of each of the two threaded rods extends into the interior of the support frame and is fixedly connected to the top of each of the two pressure plates. Each of the two threaded rods has a support arm fixedly installed at its top, and each of the two support arms has a sliding sleeve fixedly installed on the side away from each other. Each of the two sliding sleeves has a sliding rod inserted inside, and the bottom of each of the two sliding rods is fixedly connected to the top of the support frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator places the pipe on the lower clamp, and then starts the servo motor to drive the active bevel gear to rotate. The active bevel gear drives the shaft to rotate inside the four shaft seats through the driven bevel gear. When the shaft rotates, it drives the two second bevel gears to rotate through the two first bevel gears. When the two second bevel gears rotate, they drive the two active gears to rotate along the two positioning frames through the two rotating shafts. When the two active gears rotate, they drive the two threaded sleeves to rotate inside the two bushings through the two driven gears.

[0010] When the two threaded sleeves rotate, they drive the two threaded rods downward. As the two threaded rods move downward, they drive the upper clamp downward through the two support arms. When the upper clamp moves, it drives the two sliding sleeves to move downward along the surface of the two sliding rods, increasing the stability of the upper clamp's movement. When the upper clamp moves downward, it presses the pipe tightly against the lower clamp. At the same time, the two threaded rods also drive the two pressure plates downward to compress the airbags. This allows the gas inside the airbags to enter the interior of the two air cushions through the two air nozzles, the first air pipe, and the second air pipe, causing the two air cushions to expand. This effectively buffers the impact of an explosion, protecting the pipe and support frame. This provides good buffering between the pipe support and the pipe, preventing pipe damage caused by external explosive impacts and extending its service life. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] As shown in Figures 1 to 8, this utility model includes a support frame 1. Support rods 2 are fixedly installed at both ends of the top of the support frame 1. A lower clamp 3 is fixedly installed in the middle of the top of the support frame 1. An upper clamp 4 is provided above the lower clamp 3. Soft pads 5 are fixedly installed on both sides of the inner walls of the upper clamp 4 and the lower clamp 3. The elasticity of the soft pads 5 can achieve a certain buffering effect to protect the pipeline. Air cushions 6 are fixedly installed in the middle of the inner walls of the upper clamp 4 and the lower clamp 3. A servo motor 14 is fixedly installed on one side of the top of the support frame 1 via a support plate 13. A transmission assembly is provided at the output end of the servo motor 14. An airbag 10 is fixedly installed at the bottom inside the support frame 1. The first air pipe 11 is fixedly installed at the middle of the top of the airbag 10 via an air nozzle. The top end of the first air pipe 11 passes through the lower clamp 3 and is connected to the air cushion 6. The second air pipe 12 is fixedly installed at one end of the airbag 10 via an air nozzle. The upper end of the second air pipe 12 passes through the upper clamp 4 and is connected to the air cushion 6. Pressure plates 28 are provided on both sides inside the support frame 1. The transmission component is connected to the upper clamp 4 and the two pressure plates 28. When the servo motor 14 is running, it outputs power to the upper clamp 4 through the transmission component, causing the upper clamp 4 to move down and press the pipe. A pressure relief valve is fixedly installed on the surface of the pipe, giving it the ability to release pressure in an emergency, and causing the two pressure plates 28 to move down and squeeze the airbag 10.

[0024] In use, the operator places the pipe on the lower clamp 3, and then starts the servo motor 14 to drive the transmission component. When the transmission component is running, it moves the upper clamp 4 downward, pressing the pipe tightly against the lower clamp 3. At the same time, the transmission component also moves the two pressure plates 28 downward to compress the airbag 10, so that the gas inside the airbag 10 enters the interior of the two air cushions 6 through the two air nozzles, the first air pipe 11 and the second air pipe 12, causing the two air cushions 6 to expand. This effectively buffers the impact of an explosion, thus protecting the pipe and the support frame 1. This provides good buffering between the pipe support and the pipe, preventing damage to the pipe caused by external explosion impact and improving its service life.

[0025] The transmission assembly includes a drive bevel gear 15, which is fixedly mounted on the output end of the servo motor 14. A driven bevel gear 16 is meshed with one side of the surface of the drive bevel gear 15. A shaft 17 is fixedly mounted in the middle of the driven bevel gear 16. The surface of the shaft 17 is rotatably connected to the top of the support frame 1 through four bearings 18. First bevel gears 19 are fixedly mounted at both ends of the shaft 17. Second bevel gears 20 are meshed with the lower part of the surface of the first bevel gears 19. A rotating shaft 21 is fixedly mounted in the middle of each of the second bevel gears 20. The bottom of each rotating shaft 21 is rotatably connected to the top of the support frame 1. A drive gear 22 is fixedly mounted on the top of each rotating shaft 21. A positioning frame 23 is rotatably mounted on the top of each drive gear 22. The bottoms of both positioning frames 23 are fixedly connected to the top of the support frame 1.

[0026] The operator starts the servo motor 14 to drive the active bevel gear 15 to rotate. The active bevel gear 15 drives the shaft 17 to rotate inside the four bearings 18 through the driven bevel gear 16. When the shaft 17 rotates, it drives the two second bevel gears 20 to rotate through the two first bevel gears 19. When the two second bevel gears 20 rotate, they drive the two active gears 22 to rotate along the two positioning frames 23 through the two rotating shafts 21.

[0027] One side of each drive gear 22 is meshed with a driven gear 24. Each driven gear 24 has a threaded sleeve 25 fixedly installed inside. Each threaded sleeve 25 has a bushing 26 rotatably installed in the middle of its surface. Each bushing 26 is fixedly connected to the top of the support frame 1. Each threaded sleeve 25 has a threaded rod 27 threadedly connected inside. The bottom of each threaded rod 27 extends into the support frame 1 and is fixedly connected to the top of each of the two pressure plates 28. Each threaded rod 27 has a support arm 7 fixedly installed on its top. Each support arm 7 has a sliding sleeve 8 fixedly installed on its opposite side. Each sliding sleeve 8 has a sliding rod 9 inserted inside. The bottom of each sliding rod 9 is fixedly connected to the top of the support frame 1.

[0028] When the two driving gears 22 rotate, they drive the two threaded sleeves 25 to rotate inside the two bushings 26 via the two driven gears 24. When the two threaded sleeves 25 rotate, they drive the two threaded rods 27 to move downward. When the two threaded rods 27 move downward, they drive the upper clamp 4 to move downward via the two support arms 7. When the upper clamp 4 moves, it drives the two sliding sleeves 8 to move downward along the surface of the two sliding rods 9, which increases the stability of the upper clamp 4 when it moves. When the upper clamp 4 moves downward, it presses the pipe tightly onto the lower clamp 3. At the same time, the two threaded rods 27 move downward, which also drives the two pressure plates 28 to move downward and squeeze the airbag 10. This allows the gas inside the airbag 10 to enter the interior of the two air cushions 6 through the two air nozzles, the first air pipe 11, and the second air pipe 12, causing the two air cushions 6 to expand. This effectively buffers the impact of the explosion and protects the pipe and support frame 1.
