Description

Technical Field

[0001] This invention relates to the field of fastener safety training technology, specifically to a fastener safety training platform. Background Technology

[0002] In addition to the specified tightening torque, fastener connections on aircraft require measures to prevent loosening, namely fastener safety devices. When an aircraft is in a high-vibration environment, several components connected by fasteners will experience frequent, minute displacements. When these relative displacements occur repeatedly, the fasteners may loosen, which is extremely dangerous for flight. Furthermore, the types and installation locations of fastener safety devices on aircraft are very complex. Therefore, maintenance personnel training requires repeated practice on safety measures, such as fuse safety, cotter pin safety, locking clip safety, spring clip safety, pipeline safety, connector safety, and cable safety, as well as training on different operating angles and positions.

[0003] Currently, fastener safety training tables are typically fixed and cannot be moved during use. Furthermore, the positions and angles of the bolts are relatively fixed, which can lead to monotonous training. To increase the richness and effectiveness of training, the number of training tables needs to be increased, thus increasing costs. Therefore, we propose a new fastener safety training table.

[0040] The technical solutions of 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.

[0041] See also Figure 1-11 The present invention provides a technical solution: Embodiment 1, a fastener safety training platform 1, comprising: as shown in the figure Figures 1-3As shown, the base 10 mainly serves a supporting function.

[0042] like Figures 1-11 As shown, the training rack 20 is in the shape of a regular hexahedron. The training rack 20 is equipped with a first mounting plate 21, a second mounting plate 22, a third mounting plate 23, a fourth mounting plate 24, a fifth mounting plate 25, and a sixth mounting plate 26.

[0043] The first mounting plate 21, the third mounting plate 23, and the fifth mounting component are spaced apart. The training frame 20 primarily serves for mounting and support. Specifically, the training frame 20 has a regular hexahedral structure, thus having six sides: the first mounting plate 21, the second mounting plate 22, the third mounting plate 23, the fourth mounting plate 24, the fifth mounting plate 25, and the sixth mounting plate 26.

[0044] The first training component 30, mounted on the first mounting plate 21, is used to train the fuse's side-hole double-strand double-connection operation. The second training component 40, mounted on the third mounting plate 23, is used to train the fuse's side-hole double-strand triple-connection operation. The third training component 50, mounted on the fifth mounting plate 25, is used to train the fuse's through-hole double-strand double-connection operation and through-hole single-strand quadruple-connection operation.

[0045] like Figures 1-11 As shown, three sets of fuse feeding assemblies 60 are provided, respectively mounted on the second mounting plate 22, the fourth mounting plate 24, and the sixth mounting plate 26, for supplying and cutting fuses. The fuse feeding assemblies 60 are mainly used to provide fuses to operators when fastening fasteners, preventing fuse loss. Furthermore, the fuse feeding assemblies 60 can cut fuses, eliminating the need for cutting tools and making the cutting operation more convenient. In addition, by mounting the three sets of fuse feeding assemblies 60 on the second mounting plate 22, the fourth mounting plate 24, and the sixth mounting plate 26, fuse feeding assemblies 60 are provided on adjacent sides regardless of whether the operator is using the first training assembly 30, the second training assembly 40, or the third training assembly 50, making fuse feeding more convenient.

[0046] like Figure 2 As shown, the drive assembly 70 is mounted on the base 10 and is used to drive the training frame 20 to rotate. Mounting the drive assembly 70 on the base 10 secures some components of the drive assembly 70, making its installation more robust and stable, and allowing it to function better. Specifically, the drive assembly 70 can adjust the angle of the training frame 20, thereby simulating training on fastener safety under various angle conditions, resulting in a wider range of applications, better flexibility, and ease of use.

[0047] Therefore, by setting the first training component 30, the second training component 40, and the third training component 50 on the training rack 20, it is possible to achieve double-strand double-connection operation of fuses with side holes, triple-strand double-connection operation of fuses with side holes, double-strand double-connection operation of fuses with through holes, and quadruple-strand operation of fuses with through holes. This provides more comprehensive training, eliminates the need for multiple training tables, and saves cost and space. By setting multiple sets of fuse feeding components 60 on the training rack 20, it is easier to provide fuses to the operator, avoiding the steps of losing fuses and using cutting tools, making operation simpler. Furthermore, the training rack 20 can be rotated using the drive component 70, thereby adjusting the angles of the first training component 30, the second training component 40, and the third training component 50, enabling multi-angle training and further improving the comprehensiveness of the training. In addition, as... Figure 5 and Figure 6 As shown, the first training component 30 includes: a plurality of first rectangular holes 31 arranged parallel to each other on the first mounting plate 21; a first bolt 32 and a second bolt 33 passing through the rectangular holes; the first bolts 32 and the second bolts 33 being spaced apart along the length of the first rectangular holes 31; the bolt heads of the first bolts 32 and the second bolts 33 extending outside the first rectangular holes 31; and the bolt tails of the first bolts 32 and the second bolts 33 extending into the first rectangular holes 31 and into the interior of the training frame 20. It should be noted that both the first bolts 32 and the second bolts 33 are provided with side holes for threading fuses.

[0048] The first training component 30 also includes a first adjustment component 34, which is used to adjust the distance between the first bolt 32 and the second bolt 33, so that it can be used for fuse drilling training with different distances between the first bolt 32 and the second bolt 33.

[0049] The first adjustment assembly 34 includes: two first mounting seats 341 and two L-shaped second mounting seats 342 fixedly connected to both sides of the inner wall of the first mounting plate 21; a first double-ended screw 343 rotatably connected between the first mounting seats 341 and the second mounting seats 342 on the same side; a first adjustment rod 345 threadedly connected between one side of the two first double-ended screws 343; a second adjustment rod 346 threadedly connected between the other side of the two first double-ended screws 343; and a plurality of first fixing seats 347 provided on the first adjustment rod 345, which are engaged with the bolt tail threads of the plurality of first bolts 32, and the first fixing seats 347 are used to fix the first bolts 32. The second adjusting rod 346 is provided with multiple second fixing seats 348 that mate with the bolt tail threads of multiple second bolts 33. The second fixing seats 348 are used to fix the second bolts 33. One end of the first double-ended screw 343 passes through the second mounting seat 342 and is fixedly connected to the first bevel gear 3401. The first transmission rod 3402 is rotatably connected between the two second mounting seats 342. Two second bevel gears 3403 that mate with the first bevel gears 3401 on both sides are fixedly connected to the first transmission rod 3402. The inner wall of the first mounting plate 21 is also provided with an L-shaped first mounting bracket 3404. The first worm gear 3405 is rotatably connected to the first mounting bracket 3404. One end of the first transmission rod 3402 near the first worm gear 3405 extends out of the second mounting seat 342 and is fixedly connected to the first worm wheel 3406 that mates with the first worm gear 3405. One end of the first worm gear 3405 extends out of the first mounting bracket 3404 and is fixedly connected to the first knob 3407. It should be noted that the first double-ended screw 343, i.e., the screw, has opposite threads on both sides.

[0050] In use, when it is necessary to adjust the distance between the first bolt 32 and the second bolt 33, the first knob 3407 is rotated. The rotation of the first knob 3407 will drive the first worm gear 3405 to rotate, which in turn will drive the first worm wheel 3406 to rotate. The rotation of the first worm wheel 3406 will then drive the first transmission rod to rotate, which in turn will drive the second bevel gears 3403 on both sides to rotate. Through the meshing of the second bevel gears 3403 with the corresponding first bevel gears 3401, the first double-headed screws 343 on both sides can be driven to rotate. Thus, the first adjusting rod 345 and the second adjusting rod 346 will move closer or further apart, thereby realizing the adjustment of the distance between the first bolt 32 and the second bolt 33, which is convenient for training operations of double-strand double-connection of side holes with various distances.

[0051] In addition, such as Figures 10-11As shown, the second training component 40 includes: an I-shaped hole 41 and two parallel second rectangular holes 42 and a third rectangular hole 43 on the third mounting plate 23. The I-shaped hole 41 has two parallel holes parallel to the second rectangular holes 42 and one vertical hole perpendicular to the second rectangular holes 42. The two ends of the vertical hole are connected to the two parallel holes respectively. A third bolt 44, a fourth bolt 45, and a fifth bolt 46 are respectively installed through the I-shaped hole 41, the second rectangular holes 42, and the third rectangular holes 43. The bolt heads of the third bolts 44, 45, and 46 extend to the outside of the third mounting plate 23, and the bolt tails extend into the inside of the third mounting plate 23 and extend into the inside of the training frame 20. It should be noted that the third bolts 44, 45, and 46 are all provided with side holes for passing through fuses, and the third bolt 44 can move inside the bow-shaped hole.

[0052] Specifically, the second training component 40 further includes a second adjustment component 47 and a third adjustment component 48. The second adjustment component 47 is used to adjust the position of the third bolt 44 within the I-shaped hole 41, and the third adjustment component 48 is used to adjust the positions of the fourth bolt 45 and the fifth bolt 46 within the second rectangular hole 42 and the third rectangular hole 43, respectively. The second adjustment component 47 includes two third mounting seats 471 and a U-shaped second mounting bracket 472. The second mounting bracket 472 is slidably mounted on the third mounting plate 23. The two third mounting seats 471 are respectively disposed on both sides of the I-shaped hole 41, and the two third mounting seats 471 on both sides are connected together. A first screw 473 is rotatably connected to the second mounting bracket 472. The first screw 473 is parallel to the parallel part 411. A third fixing seat 474 is provided on the first screw 473, which is threaded to engage with the threaded end of the third bolt 44. One end of the first screw 473 extends out of the third mounting bracket 471 on one side and is fixedly connected to a second knob 475. A second screw 476 is rotatably connected to the second mounting bracket 472. The second screw 476 is parallel to the vertical part 412 and is threadedly connected to the third fixing seat 474. One end of the second screw 476 extends out of the second mounting bracket 472 and is fixedly connected to a third knob 477. When it is necessary to adjust the position of the third bolt 44 in the I-hole 41, turn the third knob 477. The third knob 477 will drive the second screw 476 to rotate. The rotation of the second screw 476 will then drive the third bolt 44 to move in the vertical part 412 through the third fixing seat 474. When the third bolt 44 is located in the parallel part 411, turn the second knob 475. The second knob 475 will drive the first screw 473 to rotate. The rotation of the first screw 473 will drive the third bolt 44 to move in the parallel part 411 through the third fixing seat 474. This will enable the third bolt 44 to move in the I-hole 41. When the third bolt 44 moves in the parallel part 411, the second mounting bracket 472 will also move on the third mounting plate 23.

[0053] The third adjustment component 48 includes: two fourth mounting seats 481, which are respectively disposed on both sides of the second rectangular hole 42. Two parallel third screws 482 and fourth screws 483 are rotatably connected between the two fourth mounting seats 481. The third screws 482 and fourth screws 483 are respectively disposed opposite to the second rectangular hole 42 and the third rectangular hole 43. The third screw 482 is provided with a fourth fixing seat 484 that engages with the bolt tail thread of the fourth bolt 45. One end of the third screw 482 passes through one side of the fourth mounting seat 481 and is fixedly connected to a fourth knob 486. The fourth screw 483 is provided with a fifth fixing seat 485 that engages with the bolt tail thread of the fifth bolt 46. One end of the fourth screw 483 passes through one side of the fourth mounting seat 481 and is fixedly connected to a fifth knob 487. When the position of the fourth bolt 45 needs to be adjusted, the fourth knob 486 is turned. The rotation of the fourth knob 486 will drive the third screw 482 to rotate. The rotation of the third screw 482 can drive the position of the fourth bolt 45 in the second rectangular hole 42 through the transmission of the fourth fixing seat 484, thereby realizing the adjustment of the position of the fourth bolt 45.

[0054] Similarly, when the position of the fifth bolt 46 needs to be adjusted, the fifth knob 487 is rotated. The rotation of the fifth knob 487 drives the fourth screw 483 to rotate. The rotation of the fourth screw 483, through the transmission of the fifth fixing seat 485, can move the fifth bolt 46 within the third rectangular hole 43, thus allowing adjustment of the position of the fifth bolt 46. In this way, the positions of the third bolt 44, the fourth bolt 45, and the fifth bolt 46 can be adjusted, facilitating training operations on the fuse side hole double-strand triple-connector under various distances and positions, improving the applicability of the device and expanding the training range.

[0055] Furthermore, such as Figures 7-9As shown, the third training component 50 includes: a sixth bolt 51, a seventh bolt 52, an eighth bolt 53, and a ninth bolt 54 that pass through the fifth mounting plate 25. The line connecting the sixth bolt 51 and the seventh bolt 52 is parallel to the axis of the training frame 20, and the line connecting the eighth bolt 53 and the ninth bolt 54 is also parallel to the axis of the training frame 20. The bolt heads of the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54 are all located outside the fifth mounting plate 25, and the bolt tails of the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54 extend into the interior of the fifth mounting plate 25 and into the interior of the training frame 20. It should be noted that the bolt heads of the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54 are all provided with through holes for inserting fuses, and for corresponding training in double-strand double-link operation or single-strand quadruple-link operation. The line connecting the sixth bolt 51 and the seventh bolt 52 is parallel to the axis of the training frame 20, and the line connecting the eighth bolt 53 and the ninth bolt 54 is also parallel to the axis of the training frame 20. For example, the center lines connecting the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54 can form a rectangle. The third training component 50 also includes a fourth adjustment component 55, which is used to selectively clamp and release the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54 to fix and adjust their angles. This allows for changing the perforation direction on the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54 during training for double-strand perforation or single-strand perforation, thus facilitating multi-angle perforation training.

[0056] Specifically, the fourth adjustment component 55 includes two fifth mounting seats 551 and two sixth mounting seats 552. The two fifth mounting seats 551 and the two sixth mounting seats 552 are respectively disposed on both sides of the inner wall of the fifth mounting plate 25. A first four-headed screw 553 is rotatably connected between the fifth mounting seat 551 and the sixth mounting seat 552 on one side. The first four-headed screw 553 includes a first threaded section, a second threaded section, a first smooth section, a third threaded section, and a fourth threaded section. The threads of the first threaded section and the second threaded section are opposite, and the threads of the third threaded section and the fourth threaded section are opposite. A second four-headed screw 554 is rotatably connected between the fifth mounting seat 551 and the sixth mounting seat 552 on the other side. The second four-headed screw includes a fifth threaded section, a sixth threaded section, a second smooth section, a seventh threaded section, and an eighth threaded section. The threads of the sixth threaded section and the seventh threaded section are opposite, and the threads of the eighth threaded section and the ninth threaded section are opposite.

[0057] The fourth adjustment assembly 55 further includes: a first clamping plate 555, a second clamping plate 556, a third clamping plate 557, and a fourth clamping plate 558. The two ends of the first clamping plate 555 are threaded to a first threaded segment and a fifth threaded segment, respectively. The two ends of the second clamping plate 556 are threaded to a second threaded segment and a sixth threaded segment, respectively. The two ends of the third clamping plate 557 are threaded to a third threaded segment and a seventh threaded segment, respectively. The two ends of the fourth clamping plate 558 are threaded to a fourth threaded segment and an eighth threaded segment, respectively. The first clamping plate 555 is provided with a first clamping groove 5551 and a second clamping groove 5552. The second clamping plate 556 is provided with a third clamping groove 5561 and a fourth clamping groove 5562. The first clamping groove 5551 and the third clamping groove 5561 cooperate to clamp the sixth bolt 51. The second clamping groove 5552 and the fourth clamping groove 5562 cooperate to clamp the seventh bolt. 52. Clamping is performed. The third clamping plate 557 is provided with a fifth clamping groove 5571 and a sixth clamping groove. The fourth clamping plate 558 is provided with a seventh clamping groove 5581 and an eighth clamping groove 5582. The fifth clamping groove 5571 and the seventh clamping groove 5581 cooperate to clamp the eighth bolt 53. The sixth clamping groove 5572 and the eighth clamping groove 5582 cooperate to clamp the eighth bolt 53. A first pulley assembly 5502 is connected between the first smooth section and the second smooth section. A pair of seventh mounting seats 5505 are also provided on the inner wall of the fifth mounting plate 25. A second transmission rod 5501 is rotatably connected between the two seventh mounting seats 5505. A second pulley assembly 5503 is connected between the second transmission rod 5501 and the second smooth section. One end of the second transmission rod 5501 extends out of one side of the seventh mounting seat 5505 and is fixedly connected to a sixth knob 5504.

[0058] As an optional embodiment, the bolt tails of the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54 are hexahedral in shape. Therefore, the first clamping groove 5551, the second clamping groove 5552, the third clamping groove 5561, the fourth clamping groove 5562, the fifth clamping groove 5571, the sixth clamping groove 5572, the seventh clamping groove 5581, and the eighth clamping groove 5582 are all open isosceles trapezoidal structures, which facilitates the limiting of the corresponding bolts.

[0059] When it is necessary to adjust the perforation angles on the sixth bolt 51, the seventh bolt 52, the eighth bolt 53, and the ninth bolt 54, rotate the sixth knob 5504. The rotation of the sixth knob 5504 will drive the second transmission rod 5501 to rotate. The rotation of the second transmission rod 5501, through the transmission of the second pulley assembly 5503, will drive the corresponding second transmission rod 5501 to rotate. The second transmission rod 5501, through the transmission of the first pulley assembly 5502, will then drive... The second four-head screw 554 rotates, and the rotation of the second four-head screw 554, through the transmission of the second pulley assembly 5503, will drive the first four-head screw 553 to rotate, so that the first four-head screw 553 and the second four-head screw 554 can rotate simultaneously. As a result, the first clamping plate 555 and the second clamping plate 556 will move closer or further away from each other. At the same time, the third clamping plate 557 and the fourth clamping plate 558 will move closer or further away from each other, thereby realizing the limiting and releasing of the corresponding bolts.

[0060] For example, when the first clamping plate 555 and the second clamping plate 556 move away from each other, the first clamping groove 5551 and the third clamping groove 5561 release the restriction on the sixth bolt 51, so that the sixth bolt 51 can be rotated and the angle of the through hole on the sixth bolt 51 can be adjusted. When the first clamping plate 555 and the second clamping plate 556 move closer to each other, the first clamping groove 5551 and the third clamping groove 5561 begin to limit the sixth bolt 51, thereby clamping and fixing the sixth bolt 51, which facilitates the improvement of training stability.

[0061] In addition, such as Figures 3-5 As shown, the fuse feeding assembly 60 includes: clearance holes 61 respectively formed on the second mounting plate 22, the fourth mounting plate 24, and the sixth mounting plate 26; a winding shaft 62 rotatably connected between opposite sidewalls 11 within the clearance holes 61; a fuse is wound on the winding shaft 62; and the fuse feeding assembly 60 further includes: a cutting assembly 63 for cutting the fuse. By winding the fuse onto the winding shaft 62, it can be directly pulled out during use, simplifying operation and preventing fuse loss. The cutting assembly 63 is positioned on the second mounting plate 22, the fourth mounting plate 24, and the sixth mounting plate 26, replacing a portable cutting tool, making it more convenient to use and preventing tool loss.

[0062] Specifically, the cutting assembly 63 includes: a C-shaped third mounting bracket 631 fixedly connected to the second mounting plate 22, the fourth mounting plate 24, and the sixth mounting plate 26 respectively; a first cutting blade 632 is provided on the second mounting plate 22, the fourth mounting plate 24, and the sixth mounting plate 26; a second cutting blade 633 that selectively cooperates with the first cutting blade 632 is slidably connected to the third mounting bracket 631; one end of the second cutting blade 633 away from the first cutting blade 632 extends out of the third mounting bracket 631 and is fixedly connected to a pressing plate 634; and a spring 635 is fixedly connected between the pressing plate 634 and the third mounting bracket 631. When it is necessary to remove and cut the fuse, pull out the fuse, cut it to a suitable length, and then place the part to be cut on the first cutting blade 632. Press down firmly on the pressing plate 634. The pressing plate 634 will drive the second cutting blade 633 to move downward, and then cooperate with the first cutting blade 632 to cut the fuse. At this time, the spring 635 is in a compressed state. After the cutting is completed, release the pressing plate 634. The pressing plate 634 is bounced up under the force of the spring 635, which makes it easy to cut the fuse again. It is convenient and quick to use.

[0063] Additionally, the base 10 has an upward-opening structure and two opposing side walls 11. The drive assembly 70 includes a drive shaft 71, with both ends of the drive shaft 71 rotatably connected to the two side walls 11 of the base 10, and the drive shaft 71 is fixedly connected to the training frame 20. A pair of eighth mounting seats 72 are fixedly connected to the side walls 11 of the base 10, and a second worm gear 73 is rotatably connected between the two eighth mounting seats 72. One end of the second worm gear 73 extends out of the outside of one of the eighth mounting seats 72 and is fixedly connected to a seventh knob 75. The end of the drive shaft 71 near the seventh knob 75 extends out of the outside of the training frame 20 and is fixedly connected to a second worm wheel 74 that cooperates with the second worm gear 73. When it is necessary to adjust the training angles of the first training component 30, the second training component 40, and the third training component 50, the seventh knob 75 is turned. The seventh knob 75 will drive the second worm gear 73 to rotate, and the rotation of the second worm gear 73 will drive the second worm wheel 74 to rotate. The rotation of the second worm wheel 74 will then drive the training frame 20 to rotate through the transmission shaft 71, thereby realizing the adjustment of the training angles of the first training component 30, the second training component 40, and the third training component 50.
