Description

Technical Field

[0001] This invention relates to the field of aviation maintenance training bench technology, specifically to an aviation maintenance pipeline disassembly and assembly simulation training bench with a hand-cranked pump. Background Technology

[0002] Aviation maintenance skills training is a systematic education and practice process designed to cultivate professional aircraft maintenance personnel. It combines in-depth theoretical knowledge with high-standard hands-on skills to ensure that every maintenance personnel has the necessary qualifications to maintain the continuous airworthiness of aircraft.

[0003] The core systems of aircraft engines, hydraulics, fuel, and environmental control all rely on pipelines to transmit and control the media. Therefore, pipeline disassembly and assembly is one of the core skills that aircraft maintenance personnel must master. In the process of aircraft maintenance skills training, it is necessary to provide aircraft maintenance personnel with professional pipeline disassembly and assembly training.

[0004] Currently, traditional training methods for aircraft maintenance piping disassembly and assembly often involve hands-on training using real aircraft or parts of the aircraft, or traditional piping disassembly and assembly benches. While using real aircraft or parts of the aircraft provides a realistic operating environment, the high cost of real aircraft leads to resource waste in training. Furthermore, the complex piping systems of real aircraft and the cumbersome disassembly and assembly processes make it difficult for trainees to quickly master basic skills. Traditional piping disassembly and assembly benches can only perform pipe disassembly and assembly, but cannot simulate real-world situations such as oil seepage and splashing, thus failing to provide a better understanding of real-world work and reducing the training effectiveness of the benches, ultimately failing to meet the needs of users. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a simulation training bench for the disassembly and assembly of aviation maintenance pipelines with a hand-cranked pump, which solves the problem that existing training benches cannot simulate the oil pressure and splashing inside the pipelines in real-world scenarios.

The output end of the motor passes through the collection trough and is fixedly connected to a splined shaft. A worm gear is slidably connected to the outer side of the splined shaft. A hollow block is provided on the left side inside the base. The inner side of the hollow block is rotatably connected to the worm gear. A connecting rod is rotatably connected inside the hollow block. A worm wheel is fixedly connected to the outer side of the connecting rod. The worm wheel meshes with the worm gear.

[0016] This invention provides a simulation training bench for the disassembly and assembly of aviation maintenance piping with a hand-cranked pump. It has the following beneficial effects: 1. This invention connects the plug and the connector. The plug block is inserted into the slot. Rotating the plug moves the plug block in the slot, thus inserting the plug block into the plug groove and fixing the plug and connector firmly. Then, the hand pump is turned to draw oil from the tank and deliver oil to the maintenance training pipeline through the delivery pipe. This simulates the pressure changes and fluid flow in the hydraulic pipeline, providing trainees with a realistic operating feel and improving the training effect.

[0017] 2. This invention moves the frame upwards, which in turn moves the rack and pinion. As the rack and pinion moves, the driven gear rotates. When the frame moves to the front of the back plate, the ratchet is restricted from rotating due to the engagement of the pawl and ratchet. The driven gear is locked in place by the transmission rod, thus locking the frame in place. This allows the transparent protective plate to protect trainees from liquid splashes caused by pipe rupture during pressure testing, improving the practicality of the training platform.

[0018] 3. This invention collects oil during the assembly and disassembly process through a collection tank and filters the oil through a filter screen. When a large amount of impurities accumulate on the filter screen, the motor drives the worm gear to rotate through the spline shaft. Through the meshing transmission between the worm gear and the worm wheel, the connecting rod rotates. The connecting rod drives the drive gear to rotate. Since the drive gear meshes with the rack, the rotation of the drive gear will drive the hollow block to move, which will drive the scraper to move and scrape off the impurities on the filter screen, preventing the filter screen from being blocked by impurities. This ensures continuous circulation and filtration of the oil and improves the convenience of using the training platform. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 2 , Figure 3 and Figure 4 This invention provides a simulation training platform for disassembling and assembling aviation maintenance pipelines with a hand-cranked pump, including a base 1, a back plate 5 fixedly connected to the top rear side of the base 1, a training mechanism 2 provided on the front side of the base 1 to facilitate improving training effectiveness, a protective mechanism 3 provided on the front side of the base 1 to facilitate protection for trainees during pressure testing, and a filter mechanism 4 provided on the top of the base 1 to facilitate the circulation of leaked oil. Training facility 2 includes a maintenance training pipeline 21, which is installed on the front side of base 1. A support 22 is located on the left side of base 1, and an oil tank 23 is located on top of support 22. A hand pump 24 is connected to the top right side of the oil tank 23, allowing the hand pump 24 to draw oil from the tank. A delivery pipe 25 is connected to the output end of the hand pump 24, and a connector 26 is connected to the right end of the delivery pipe 25. The hand pump 24 delivers oil to the connector 26 through the delivery pipe 25. A connector 27 is connected to the right side of the connector 26, and connector blocks 28 are fixedly connected to both the upper and lower sides of the right arm of the connector 26. A connector 29 is connected to the left side of the maintenance training pipeline 21. The connector 29 has slots 210 on both the upper and lower sides of its left wall. The plug block 28 engages with the slot 210. The connector 29 and the plug 26 can be fixed by the plug block 28 and the slot 210. The training institution 2 also includes a fixing block 1 212, which is fixedly connected to the bottom of the plug 26. A pin 213 is slidably connected to the inner side of the fixing block 1 212. A fixing block 214 is fixedly connected to the bottom of the connector 29. The pin 213 is plugged into the fixing block 214. A rubber sheet 211 is fixedly connected to the right side of the plug 26. By inserting the pin 213 into the fixing block 214, the plug 26 can be prevented from disengaging due to rotation. Specifically, at the start of the training operation, the connector 26 needs to be aligned with the connector 29 and inserted. The insert 27 is then inserted into the connector 29, and the plug block 28 is also embedded in the slot 210. Then, the connector 26 is rotated, and the plug block 28 moves within the slot 210 and is inserted tightly into the slot 210, thereby locking the connector 26 and the connector 29 together. The pin 213 is then inserted into the fixing block 214 to prevent the connector 26 from dislodging due to rotation. The hand pump 24 is then cranked, drawing oil from the oil tank 23. The oil flows sequentially through the delivery pipe 25, the connector 26, and the connector 29, entering the maintenance training pipeline 21, thereby simulating the pressure changes and fluid flow in a real hydraulic pipeline, thus improving the trainees' hands-on experience and training quality.

[0023] Reference Figure 1 , Figure 2 and Figure 5 The protective mechanism 3 includes a frame 31, which is slidably connected to the front side of the base 1. A transparent protective plate 32 is fixedly connected to the inner side of the frame 31. Racks 33 are fixedly connected to both the left and right sides of the frame 31. When the frame 31 moves upward, it drives the racks 33 to move. Fixed boxes 34 are fixedly connected to the left and right ends of the top inner side of the base 1. A transmission rod 35 is rotatably connected to one side of the inner side of the fixed box 34. A driven gear 36 is fixedly connected to the rear side of the outer wall of the transmission rod 35. A window 37 is opened on one side of the fixed box 34. The outer side of the driven gear 36 passes through the window 37 and meshes with the racks 33. When the racks 33 move, they drive the driven gear 36 to rotate. A ratchet 38 is fixedly connected to the front side of the outer wall of the transmission rod 35. A rotating rod 39 is rotatably connected to the other side of the inner side of the fixed box 34. The front end of the rotating rod 39 passes through the fixed box 34. A pawl 310 is fixedly connected to the front side of the outer wall of the rotating rod 39. The pawl 310 is engaged with the ratchet 38. The pawl 310 can limit the rotation of the ratchet 38, and thus the rotating rod 39 can lock the driven gear 36. The protective mechanism 3 also includes a torsion spring 311. The torsion spring 311 is located on the rear side of the outer wall of the rotating rod 39. The front and rear ends of the torsion spring 311 are fixedly connected to the fixed box 34 and the pawl 310, respectively. The torsion spring 311 can pull the pawl 310 so that the pawl 310 can engage with the ratchet 38. The protective mechanism 3 also includes a knob 312. The knob 312 is fixedly connected to the front side of the rotating rod 39. A handle 313 is fixedly connected to the bottom front side of the frame 31. The handle 313 makes it convenient for students to move the frame 31. Specifically, after the trainee completes the disassembly and assembly training of the maintenance training pipeline 21, a pressure test needs to be performed on the pipeline to check the installation quality. At this time, pull the handle 313 upwards, and the handle 313 will move the frame 31 upwards together. The movement of the frame 31 will drive the rack 33 to move synchronously. Since the driven gear 36 and the rack 33 mesh with each other, the rack 33 will drive the driven gear 36 to rotate. After the frame 31 moves to the front of the back plate 5, release the handle 313. Because the pawl 310 will... Engaging with ratchet 38, thus limiting the reverse rotation of ratchet 38, and locking the position of driven gear 36 through transmission rod 35, thereby fixing the position of frame 31. The transparent protective plate 32 inside frame 31 can protect trainees during pressure testing, preventing injury from liquid splashed out due to accidental pipeline rupture. After the test, rotating rod 39 will cause pawl 310 to disengage from ratchet 38, releasing the lock on driven gear 36, and frame 31 can be smoothly lowered and reset.

[0024] Reference Figure 6 , Figure 7 and Figure 8 The filtration mechanism 4 includes a collection hopper 41, which is fixedly connected to the top of the base 1. A collection trough 42 is fixedly connected to the bottom of the collection hopper 41, penetrating the base 1. A filter screen 43 is fixedly connected to the inner center of the collection trough 42, capable of filtering oil. A motor 44 is fixedly connected to the top left side of the collection trough 42. The output end of the motor 44 penetrates the collection trough 42 and is fixedly connected to a splined shaft 45, which drives the splined shaft 45 to rotate. A worm gear 47 is slidably connected to the outer side of the splined shaft 45, enabling the worm gear 47 to rotate. A hollow block 46 is provided on the left side inside the base 1, with its inner side rotatably connected to the worm gear 47. A connecting rod 48 is rotatably connected inside the hollow block 46, and a worm wheel 49 is fixedly connected to the outer side of the connecting rod 48. The worm wheel 49 meshes with the worm gear 47, and when the worm gear 47 rotates, the worm wheel 49 drives the connecting rod 48 to rotate. The connecting rod 48 rotates, and the front end of the connecting rod 48 passes through the hollow block 46 and is fixedly connected to the drive gear 410. The connecting rod 48 will drive the drive gear 410 to rotate. The top of the inner front end of the collection tank 42 is fixedly connected to the rack 411. The rack 411 meshes with the drive gear 410. When the drive gear 410 rotates, it will drive the hollow block 46 to move through the connecting rod 48. The bottom of the hollow block 46 is fixedly connected to the scraper 412. The hollow block 46 will drive the scraper 412 to move and scrape the impurities on the filter screen 43. The filter mechanism 4 also includes a guide rod 413. The guide rod 413 is fixedly connected to the rear side of the outer wall of the collection tank 42. The outer side of the guide rod 413 is slidably connected to the guide block 414. The front side of the guide block 414 is fixedly connected to the hollow block 46. Through the cooperation of the guide rod 413 and the guide block 414, the movement of the hollow block 46 can be guided. Specifically, during disassembly and testing, leaked oil is collected in the collection hopper 41 and flows into the collection tank 42 below. The oil first passes through the filter screen 43 in the tank. The filter screen 43 can intercept various impurities mixed in the oil. When there are many impurities on the filter screen 43, the start motor 44 drives the spline shaft 45 to rotate. The spline shaft 45 drives the worm gear 47 to rotate. At this time, the worm wheel 49 meshing with the worm gear 47 also rotates. The worm wheel 49 drives the drive gear 410 to rotate through the connecting rod 48. The drive gear 410 meshes with the rack 411 fixed inside the collection tank 42. Therefore, when the drive gear 410 rotates, it will move along the fixed rack 411, thereby driving the hollow block 46 and the scraper 412 to move horizontally together. During the movement, the scraper 412 will scrape off the impurities on the surface of the filter screen 43, preventing the filter screen 43 from being blocked by impurities, thus realizing continuous circulation filtration of leaked oil.

[0025] Reference Figure 1 and Figure 2 The training institution 2 also includes a pressure gauge 215, which is located on the outside of the conveying pipe 25. The bottom left and right sides of the support 22 are rotatably connected with walking wheels 216. The training institution 2 also includes a feed inlet 217, which is connected to the top left side of the oil tank 23. The top of the feed inlet 217 is threaded with a feed cover 218. Opening the feed cover 218 allows oil to be added to the oil tank 23. Specifically, pressure gauge 215 can monitor the pressure of oil in the pipeline, and the support 22 can be moved by the walking wheels 216, so as to replenish oil in the maintenance training pipeline 21 installed on different training platforms. When the oil in the oil tank 23 is insufficient, the feed cover 218 can be opened to replenish it through the feed port 217.

[0026] Reference Figure 1 and Figure 6 The filter mechanism 4 also includes a liquid outlet 415, which is connected to the bottom left side of the collection tank 42. A liquid outlet cover 416 is threadedly connected to the left side of the liquid outlet 415, and the liquid outlet cover 416 can close the liquid outlet 415. Specifically, by opening the liquid outlet cap 416, the oil collected in the collection tank 42 can be released through the liquid outlet 415.

[0027] Working principle: When using this training platform for training, first connect the connector 26 and the connector 29. The insertion tube 27 will be inserted into the connector 29, and the insertion block 28 will be inserted into the slot 210. Then rotate the connector 26. At this time, the insertion block 28 will move in the slot 210, so that the insertion block 28 is inserted into the insertion groove, and the connector 26 and the connector 29 are firmly fixed. The pin 213 is inserted into the fixing block 214 to prevent the connector 26 from rotating out. After the connector 26 is connected, crank the hand pump 24. The hand pump 24 will draw oil from the oil tank 23. The drawn oil will then pass through the delivery pipe 25, the connector 26 and the connector 29 in sequence into the maintenance training pipeline 21, simulating the pressure changes and fluid flow in the hydraulic pipeline, thereby improving the training effect of the trainees. After the trainees complete the disassembly and assembly training of the maintenance training pipeline 21, a pressure test needs to be performed on the maintenance training pipeline 21. At this time, pull the handle 313 upward, and the handle 313 will drive the frame 31 to move upward. The frame 31 will drive the rack 33 to move simultaneously. Since the driven gear 36 is engaged with the rack 33, the movement of the rack 33 will drive the driven gear 36 to rotate. When the frame 31 moves to the front of the back plate 5, release the handle 313. At this time, since the pawl 310 is engaged with the ratchet 38, the ratchet 38 will be restricted from rotating. Then, the position of the driven gear 36 will be locked through the transmission rod 35, so that the position of the frame 31 can be locked. At this time, the transparent protective plate 32 on the inner side of the frame 31 can protect the trainees from liquid splashing caused by pipeline rupture during the pressure test. After the pressure test is completed, rotate the rotating rod 39. The rotating rod 39 will drive the pawl 310 to disengage from the ratchet 38 and engage the lock on the driven gear 36, so that the frame 31 can be reset. Finally, during the disassembly and assembly of the maintenance training pipeline 21, any leaked oil will enter the collection tank 42 through the collection hopper 41. At this time, the filter screen 43 can filter the oil, removing impurities. The motor 44 drives the spline shaft 45 to rotate, which in turn drives the worm 47 to rotate. Since the worm wheel 49 meshes with the worm 47, the worm wheel 49 will rotate when the worm 47 rotates. This rotation, along with the connecting rod 48, will drive the drive gear 410 to rotate. Because the drive gear 410 meshes with the rack 411, and the rack 411 is fixed in the collection tank 42, the rotation of the drive gear 410 will move the hollow block 46, which in turn will move the scraper 412 to scrape off the impurities on the filter screen 43, preventing the filter screen 43 from being clogged and ensuring continuous circulation and filtration of the oil.
