Description

Technical Field

[0001] This utility model belongs to the technical field of special equipment testing devices, specifically a special equipment fault simulation and testing platform. Background Technology

[0002] The Special Equipment Fault Simulation and Testing Platform is a comprehensive experimental system integrating advanced technologies. It aims to simulate the operating status of special equipment (such as elevators, cranes, and pressure vessels) under various complex working conditions and potential fault conditions, and to conduct comprehensive performance testing, fault diagnosis, and safety assessment. By simulating different fault scenarios, the platform helps users gain a deeper understanding of the equipment's behavior under abnormal conditions, providing crucial information for optimized equipment design, safe maintenance, and emergency plan development. Its applications are wide-ranging, including safety supervision of special equipment, technology research and development, operator training, and accident emergency response, making it an indispensable tool for ensuring the safe operation of special equipment. Pressure vessels may be affected by external vibrations during use, such as earthquakes, transportation, and mechanical vibrations; vibration testing can assess the structural integrity and safety of these devices under vibration conditions.

[0003] Existing pressure vessel vibration testing equipment has limited testing capabilities. In actual operation, pressure vessels may face the combined effects of vibration and swaying. For example, on offshore platforms, pressure vessels are not only subject to swaying caused by waves, but also to vibrations from platform equipment. Relying solely on vibration simulation cannot realistically assess the performance and reliability of pressure vessels, and it is difficult to provide more accurate data for the design, manufacture, and maintenance of vessels. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a special equipment fault simulation and testing platform, which effectively solves the problem that the existing pressure vessel vibration testing device has a single testing capability. In actual operation, pressure vessels may face the combined effects of vibration and shaking at the same time. The performance and reliability of pressure vessels cannot be more realistically evaluated by a single vibration simulation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special equipment fault simulation and testing platform, comprising a device body, a vibrating plate on the top of the device body, four sliding sleeves fixedly installed on the circumferential surface of the vibrating plate, sliding rods inserted inside the sliding sleeves, the bottom ends of the four sliding rods fixedly connected to the top of the device body, springs sleeved on the upper part of the surface of the four sliding rods, the two ends of the four springs fixedly connected to the sliding rods and sliding sleeves respectively, a shaking table on the top of the vibrating plate, two electric push rods fixedly installed on the circumferential surface of the shaking table, the transmission ends of the two electric push rods extending into the interior of the shaking table and fixedly installed with clamping clamps, a servo motor fixedly installed at the bottom inner part of the device body, a transmission component at the output end of the servo motor, the transmission component being connected to the vibrating plate and the shaking table, the servo motor outputting power to the vibrating plate and the shaking table through the transmission component during operation.

[0006] Preferably, the transmission assembly includes a shaft, which is fixedly installed at the output end of the servo motor. A support frame is rotatably mounted on the surface of the shaft via a bearing. The bottom of the support frame is fixedly connected to the inner bottom of the main body of the device. A drive gear is fixedly installed at the top of the shaft. A driven gear is meshed with one side of the drive gear. The bottom of the driven gear is rotatably connected to one side of the top of the support frame. An internal gear ring is meshed with one side of the driven gear. A turntable is fixedly installed at the top of the internal gear ring. Pushing blocks are fixedly installed at equal intervals in a ring on the top of the turntable. Four rollers are closely attached to the upper surface of the turntable, and the tops of the four rollers are fixedly connected to the bottom of the vibratory plate.

[0007] Preferably, a limiting slip ring is fixedly installed on the circumferential surface of the turntable, and an annular groove is provided on the upper part of the inner wall of the main body of the device, with the limiting slip ring slidably installed inside the annular groove.

[0008] Preferably, a rectangular rod is fixedly installed on the top of the drive gear, a sleeve is movably installed on the surface of the rectangular rod, the surface of the sleeve is rotatably connected to the middle of the vibratory feeder through a bushing, a diagonal rod is fixedly installed on the top of the sleeve through a transmission disc, the top of the diagonal rod is fixedly connected to the shaking table through a connector, a rotating shaft is fixedly installed in the middle of the connector, a connecting frame is rotatably installed between the two ends of the rotating shaft, and both sides of the connecting frame are rotatably connected to the inner bottom of the vibratory feeder through a rotating frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the operator places the pressure tank on the shaking table, then activates two electric push rods to move two clamping hoops in opposite directions, thereby clamping and fixing the pressure tank. Then, the operator activates a servo motor to drive the shaft to rotate inside the bearing. When the shaft rotates, it drives the driven gear to rotate via the drive gear. When the driven gear rotates, it drives the turntable to rotate via the internal gear ring. When the turntable rotates, it causes the limiting slip ring to slide inside the annular groove, ensuring the stability of the turntable during rotation. The rotation of the turntable also drives four pushing blocks. When the four pushing blocks rotate, they intermittently push the four rollers upward. When the four rollers move upward, they drive the vibratory plate upward. When the vibratory plate moves upward, it drives the four sliding sleeves to slide along the surface of the four sliding rods and simultaneously compresses the four springs. Then, under the elastic force of the four springs, it pushes the vibratory plate downward quickly. The repeated up and down pushing can make the vibratory plate vibrate up and down. When the vibratory plate moves vertically, it will drive the sleeve to slide and extend on the surface of the rectangular rod, thereby ensuring the transmission capacity. When the vibratory plate vibrates up and down, it will drive the pressure tank to vibrate through the shaking table, thereby performing vibration testing.

[0010] While the drive gear rotates, it also drives the sleeve to rotate along the inside of the bushing via the rectangular rod. When the sleeve rotates, it drives the inclined rod to rotate via the transmission disc. When the inclined rod rotates, it drives the connector to rotate. At the same time, the connector rotates via the rotating shaft, which drives the connecting frame to rotate along the two rotating frames, thus ensuring the stability of the connector during rotation. When the connector rotates, it causes the pressure vessel to shake via the shaking table, so that vibration testing and shaking testing can be performed simultaneously. This allows the pressure vessel testing device to perform combined vibration and shaking tests simultaneously, thereby more realistically evaluating the performance and reliability of the pressure vessel and providing a more accurate basis for the design, manufacturing and maintenance of the vessel.

[0019] 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.

[0020] Depend on Figures 1 to 5 The present invention includes a device body 1, a vibrating plate 2 on top of the device body 1, four sliding sleeves 4 fixedly installed on the circumference of the vibrating plate 2, sliding rods 5 inserted inside each sliding sleeve 4, the bottom ends of the four sliding rods 5 fixedly connected to the top of the device body 1, springs 6 sleeved on the upper part of the surface of each of the four sliding rods 5, and the two ends of the four springs 6 fixedly connected to the sliding rods 5 and the sliding sleeves 4 respectively. A shaking table 7 is provided above the vibrating plate 2, two electric push rods 8 fixedly installed on the circumference of the shaking table 7, the transmission ends of the two electric push rods 8 extending into the interior of the shaking table 7 and fixedly installed with clamping hoops 9. A servo motor 10 is fixedly installed at the bottom inner part of the device body 1, and a transmission assembly is provided at the output end of the servo motor 10. The transmission assembly is connected to the vibrating plate 2 and the shaking table 7. When the servo motor 10 is running, it outputs power to the vibrating plate 2 and the shaking table 7 through the transmission assembly.

[0021] In use, the operator places the pressure tank on the shaking table 7, and then activates the two electric push rods 8 to move the two clamping clamps 9 toward each other, thereby clamping and fixing the pressure tank. Then, the operator activates the servo motor 10 to drive the transmission component to operate. When the transmission component operates, it will intermittently drive the vibratory plate 2 to move upward. When the vibratory plate 2 moves upward, it will drive the four sliding sleeves 4 to slide along the surface of the four sliding rods 5, and at the same time squeeze the four springs 6. Then, under the elastic force of the four springs 6, it will push the vibratory plate 2 to move downward quickly. The repeated up and down pushing will make the vibratory plate 2 vibrate up and down. When the vibratory plate 2 vibrates up and down, it will drive the pressure tank to vibrate through the shaking table 7, thereby conducting a vibration test.

[0022] While the transmission components are running, the pressure vessel is also shaken via the shaking platform 7, thus allowing for simultaneous vibration and shaking tests. This enables the pressure vessel testing device to perform combined vibration and shaking tests simultaneously, thereby providing a more realistic assessment of the pressure vessel's performance and reliability, and offering a more accurate basis for the design, manufacture, and maintenance of the vessel.

[0023] The transmission assembly includes a shaft 12, which is fixedly installed at the output end of the servo motor 10. A support frame 14 is rotatably mounted on the surface of the shaft 12 via a bearing 13. The bottom of the support frame 14 is fixedly connected to the inner bottom of the main body 1 of the device. A drive gear 15 is fixedly installed at the top of the shaft 12. A driven gear 16 is meshed with one side of the drive gear 15. The bottom of the driven gear 16 is rotatably connected to one side of the top of the support frame 14. An internal gear ring 17 is meshed with one side of the driven gear 16. A turntable 18 is fixedly installed at the top of the internal gear ring 17. Pushing blocks 21 are fixedly installed at equal intervals in an annular shape on the top of the turntable 18. Four rollers 11 are closely attached to the upper surface of the turntable 18, and the tops of the four rollers 11 are fixedly connected to the bottom of the vibrating plate 2. A limiting slip ring 19 is fixedly installed on the circumferential surface of the turntable 18. An annular groove 20 is opened in the upper part of the inner wall of the main body 1 of the device, and the limiting slip ring 19 is slidably installed inside the annular groove 20.

[0024] The operator starts the servo motor 10, which drives the shaft 12 to rotate inside the bearing 13. When the shaft 12 rotates, it drives the driven gear 16 to rotate through the drive gear 15. When the driven gear 16 rotates, it drives the turntable 18 to rotate through the internal gear ring 17. When the turntable 18 rotates, it drives the limiting slip ring 19 to slide inside the annular groove 20, ensuring the stability of the turntable 18 when it rotates. When the turntable 18 rotates, it drives the four pushing blocks 21 to rotate. When the four pushing blocks 21 rotate, they intermittently push the four rollers 11 to move upward. When the four rollers 11 move upward, they drive the vibrating plate 2 to move upward. When the vibrating plate 2 moves upward, it drives the four sliding sleeves 4 to slide along the surface of the four sliding rods 5, and at the same time, it squeezes the four springs 6. Then, under the elastic force of the four springs 6, it pushes the vibrating plate 2 to move downward quickly. The repeated up and down pushing can make the vibrating plate 2 vibrate up and down. When the vibrating plate 2 moves vertically, it drives the sleeve 23 to slide and extend on the surface of the rectangular rod 22, thereby ensuring the transmission capacity.

[0025] A rectangular rod 22 is fixedly installed on the top of the drive gear 15. A sleeve 23 is movably installed on the surface of the rectangular rod 22. The surface of the sleeve 23 is rotatably connected to the middle of the vibratory plate 2 through a bushing 24. A diagonal rod 26 is fixedly installed on the top of the sleeve 23 through a transmission plate 25. The top of the diagonal rod 26 is fixedly connected to the shaking table 7 through a connector 27. A rotating shaft 28 is fixedly installed in the middle of the connector 27. A connecting frame 29 is rotatably installed between the two ends of the rotating shaft 28. Both sides of the connecting frame 29 are rotatably connected to the inner bottom of the vibratory plate 2 through a rotating frame 3.

[0026] While the drive gear 15 rotates, it also drives the sleeve 23 to rotate along the inside of the bushing 24 via the rectangular rod 22. When the sleeve 23 rotates, it drives the inclined rod 26 to rotate via the transmission disc 25. When the inclined rod 26 rotates, it drives the connector 27 to rotate. At the same time as the connector 27 rotates, it drives the connecting frame 29 to rotate along the two rotating frames 3 via the rotating shaft 28, thereby ensuring the stability of the connector 27 when it rotates. When the connector 27 rotates, it drives the pressure tank to shake via the shaking table 7, so that the shaking test can be carried out at the same time as the vibration test.
