Description

Technical Field

[0001] This invention belongs to the field of auxiliary wheel disassembly and assembly technology, specifically referring to an auxiliary device for disassembling and assembling wheels for civil aircraft maintenance. Background Technology

[0002] As a core load-bearing component of the aircraft takeoff and landing system, the quality of the maintenance and disassembly of civil aircraft wheels directly affects flight safety and must meet the requirements of high-frequency and high-precision maintenance.

[0003] Currently, before disassembling and assembling the wheel, the coaxiality between the equipment and the axle needs to be manually adjusted. This relies on the experience of maintenance personnel and is prone to positioning deviations, leading to problems such as stripped nuts during disassembly and misaligned wheel installation, which affects the quality of maintenance. After the old wheel is disassembled, the coaxiality between the new wheel and the axle needs to be readjusted during installation. This operation is cumbersome and prone to deviations, affecting the stability of the wheel in subsequent use. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an auxiliary device for the installation and removal of aircraft wheels for civil aircraft maintenance. This application utilizes an air pump as a power source to drive a three-jaw chuck to fix the tire. During tire fixing, the device automatically adjusts the lateral and longitudinal positions of the three-jaw chuck and the tire, and locks the chuck position, preventing it from changing during tire installation or removal. This ensures that both the old and new tires are fixed by the three-jaw chucks on both sides, solving the technical problems of stripped threads during nut removal and misaligned wheel installation in existing technologies. A detection tube is used to determine the tire's fixing status, facilitating a switch to the nut removal process for nut removal and installation. The translation of the two-jaw chucks on both sides ensures that the new tire inherits the coaxiality of the old tire with the landing gear axle, solving the technical problem of readjusting the coaxiality of the new wheel with the axle in existing technologies.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: The present invention proposes an auxiliary equipment for disassembling and assembling aircraft wheels for civil aircraft maintenance, including a trolley frame, a transverse sliding plate slidably connected to the top wall of the trolley frame, a moving plate slidably connected to the top wall of the transverse sliding plate, a transverse sliding box slidably connected to the top wall of the moving plate, a connecting seat slidably connected to the top wall of the transverse sliding box, three-jaw chucks symmetrically fixedly connected to both sides of the connecting seat, an air pump fixedly connected to one side of the top wall of the transverse sliding plate, a transverse telescopic rod fixedly connected to the side wall of the trolley frame, the telescopic end of the transverse telescopic rod being fixedly connected to the side wall of the transverse sliding plate, and a detection tube fixedly connected to the output end of the air pump, the detection tube being hollow.

[0006] Preferably, a sealing ring and a guide post are coaxially fixedly connected at the center of the inner circumferential wall of the detection tube, with the guide post penetrating the sealing ring. A guide plate is longitudinally slidably connected to the outer circumferential wall of the guide post. A driving spring is fixedly connected to the top wall of the guide plate and the inner top wall of the detection tube. A first telescopic rod is fixedly connected to the bottom wall of the detection tube. The input end of the first telescopic rod communicates with the hollow part of the detection tube. A first switch is fixedly connected to the telescopic end of the first telescopic rod. A second telescopic rod is fixedly connected to the top wall of the sealing ring. The input end of the second telescopic rod communicates with the hollow part of the detection tube. A second switch is fixedly connected to the telescopic end of the second telescopic rod. The second switch is located above the guide plate. The first switch and the second switch are electrically connected to the air pump, respectively.

[0007] Preferably, the bottom wall of the connecting seat is fixedly connected with guide rods in a linear array, the other end of the guide rods movably penetrates the top wall of the transverse box, and a guide spring is sleeved on the guide rods. The two ends of the guide springs are fixedly connected to the bottom end of the guide rods and the top wall of the transverse box, respectively.

[0008] Preferably, the top wall of the transverse box is fixedly connected with a first electromagnet in a linear array, and the first electromagnet is located on both sides of the guide rod. The side walls of the transverse box are fixedly connected with second electromagnets, and the bottom wall of the second electromagnet is close to the top wall of the moving plate. The first electromagnet and the second electromagnet are electrically connected to the first switch respectively.

[0009] Preferably, a pneumatic box is coaxially fixedly connected to one end of the three-jaw chuck, and a pneumatic impeller is coaxially rotatably connected inside the pneumatic box. The pneumatic impeller is coaxially fixedly connected to the disc thread in the three-jaw chuck. The detection tube is connected to the outer circumferential wall of the pneumatic box through an air pipe. A disassembly telescopic rod is coaxially fixedly connected to the side wall of the pneumatic box. An electric wrench is coaxially fixedly connected to the telescopic end of the disassembly telescopic rod. The disassembly telescopic rod is electrically connected to the first switch and the electric wrench respectively. The electric wrench is electrically connected to the transverse telescopic rod and the movable telescopic rod.

[0010] Preferably, the top wall of the transverse plate is symmetrically and fixedly connected with a movable telescopic rod, the telescopic end of the movable telescopic rod is fixedly connected to the side wall of the transverse plate, and the second switch is electrically connected to the transverse telescopic rod and the movable telescopic rod.

[0011] The beneficial effects achieved by the present invention using the above structure are as follows:

[0012] 1. This application uses an air pump as a power source to drive a three-jaw chuck to fix the tire. When fixing the tire, the three-jaw chuck and the tire are automatically adjusted in the lateral and longitudinal directions and the position of the three-jaw chuck is locked. The position of the three-jaw chuck will not change due to the tire installation and removal process. The three-jaw chucks on both sides fix the new and old tires. The detection tube is used to judge the fixing status of the tire. The three-jaw chucks on both sides are moved to make the new tire inherit the coaxiality of the old tire with the wheel axle on the landing gear.

[0013] 2. When the mobile telescopic rod moves the support away from the ground, it also pushes the three-jaw chuck closer to the tire. The mobile telescopic rod moves the three-jaw chuck closer to the tire through the moving plate, the transverse box and the connecting seat. The high-pressure airflow drives the pneumatic impeller to rotate, which drives the three-jaw chuck to fix the tire coaxially.

[0014] 3. When the air pump inputs high-pressure airflow into the detection tube, the guide plate compresses and drives the spring, the three-jaw chuck clamps the tire into place, the air pressure on both sides of the guide plate is balanced, and the spring is reset, accurately triggering the first switch to determine that the current tire is fixed. When the air pump draws airflow from the detection tube, the guide plate stretches and drives the spring, the three-jaw chuck releases the tire into place, the air pressure on both sides of the guide plate is balanced, and the spring is reset, accurately triggering the second switch to determine that the current tire is released.

[0015] 4. When the three-jaw chuck is used to fix the tire coaxially, the guide rod and the guide spring form an elastic adaptive structure. If there is an installation deviation, it will drive the connecting seat to move longitudinally, adjust the longitudinal position of the three-jaw chuck, and also drive the transverse box to move on the moving plate, adjust the transverse position of the moving plate. When the first switch is triggered, the first electromagnet and the second electromagnet will start, locking the longitudinal and transverse positions of the connecting seat.

[0016] 5. After the electric wrench removes the tire, it drives the horizontal telescopic rod to move the horizontal plate, causing the new tire to inherit the axle position of the old tire, and completing the replacement of the old and new tires. Attached Figure Description

[0028] 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.

[0029] Example 1, as Figures 1-8As shown, this solution proposes an auxiliary device for disassembling and assembling aircraft wheels for civil aircraft maintenance, including a trolley frame 1. The bottom wall of the trolley frame 1 is fixedly connected with casters in a rectangular array. A lifting telescopic rod 11 is also fixedly connected to the bottom wall of the trolley frame 1 in a rectangular array. A transverse sliding plate 2 is slidably connected laterally to the top wall of the transverse sliding plate 1. A moving plate 3 is slidably connected longitudinally to the top wall of the moving plate 2. A transverse sliding box 4 is slidably connected to the top wall of the transverse sliding box 4. A connecting seat 5 is slidably connected to the top wall of the transverse sliding box 4. Three-jaw chucks 6 are symmetrically fixedly connected to both sides of the connecting seat 5. The chuck 6 is a fixture that uses a disc thread to drive and fix a circular workpiece in the prior art. An air pump 7 is fixedly connected to one side of the top wall of the transverse plate 2. A transverse telescopic rod 8 is fixedly connected to the side wall of the trolley frame 1. The telescopic end of the transverse telescopic rod 8 is fixedly connected to the side wall of the transverse plate 2. The transverse telescopic rod 8 is initially in the extended state. The distance between the three-jaw chuck 6 on the other side of the connecting seat 5 and the three-jaw chuck 6 on one side of the connecting seat 5 is equal to the telescopic distance of the transverse telescopic rod 8. The output end of the air pump 7 is fixedly connected to a detection tube 71, which is hollow.

[0030] like Figures 1-4 As shown, a sealing ring 711 and a guide post 712 are coaxially fixedly connected at the center of the inner circumferential wall of the detection tube 71, and the guide post 712 penetrates the sealing ring 711. A guide plate 713 is longitudinally slidably connected to the outer circumferential wall of the guide post 712. The guide plate 713 is configured to cooperate with the sealing ring 711. A driving spring 714 is fixedly connected to the top wall of the guide plate 713 and the inner top wall of the detection tube 71. The driving spring 714 is initially in a relaxed state. The driving spring 714 drives the guide plate 713 to cooperate with the sealing ring 711. A first telescopic rod 715 is fixedly connected to the inner bottom wall of the detection tube 71. The input end of the first telescopic rod 715 is connected to the hollow part of the detection tube 71. The telescopic end of the first telescopic rod 715 is fixedly connected to the first telescopic rod 715. A switch 716 is used. The first telescopic rod 715 is initially in a retracted state. When the air pump 7 inputs high-pressure air into the detection tube 71, the high-pressure airflow drives the guide plate 713 to move, compressing and driving the spring 714. The first telescopic rod 715 is activated and drives the first switch 716 to contact the sealing ring 711. The top wall of the sealing ring 711 is fixedly connected to a second telescopic rod 718. The input end of the second telescopic rod 718 is connected to the hollow part of the detection tube 71. The second telescopic rod 718 is initially in an extended state. The telescopic end of the second telescopic rod 718 is fixedly connected to a second switch 717. The second switch 717 is located above the guide plate 713. The first switch 716 and the second switch 717 are electrically connected to the air pump 7.

[0031] like Figures 1-3 and Figures 5-6As shown, the bottom wall of the connecting seat 5 is fixedly connected with guide rods 51 in a linear array. The other end of the guide rods 51 movably passes through the top wall of the transverse box 4. A guide spring 52 is sleeved on the guide rods 51. The two ends of the guide spring 52 are fixedly connected to the bottom end of the guide rod 51 and the inner top wall of the transverse box 4, respectively. The guide spring 52 is initially in an unstretched state.

[0032] like Figures 1-3 and Figures 5-6 As shown, the top wall of the transverse box 4 is linearly arrayed with a first electromagnet 41, which is fixedly connected to both sides of the guide rod 51. When the first electromagnet 41 is activated, it magnetically attracts the guide rod 51, thus fixing the guide rod 51 and locking it. The two side walls of the transverse box 4 are fixedly connected with second electromagnets 42, whose bottom walls are close to the top wall of the moving plate 3. When the second electromagnet 42 is activated, it magnetically attracts the moving plate 3, thus fixing the moving plate 3 and locking the transverse box 4. The first electromagnet 41 and the second electromagnet 42 are electrically connected to the first switch 716.

[0033] like Figures 1-3 and Figures 7-8 As shown, a pneumatic housing 61 is coaxially fixedly connected to one end of the three-jaw chuck 6. A pneumatic impeller 65 is coaxially rotatably connected inside the pneumatic housing 61. The pneumatic impeller 65 is coaxially fixedly connected to the disc thread in the three-jaw chuck 6. The detection tube 71 is connected to the outer circumferential wall of the pneumatic housing 61 through an air pipe. A disassembly telescopic rod 62 is coaxially fixedly connected to the side wall of the pneumatic housing 61. An electric wrench 64 is coaxially fixedly connected to the telescopic end of the disassembly telescopic rod 62. The disassembly telescopic rod 62 is connected to the first switch 716 and the electric wrench 64 respectively. The wrench 64 is electrically connected to the horizontal telescopic rod 8 and the moving telescopic rod 21. When the first switch 716 is triggered, the disassembly telescopic rod 62 is started and drives the electric wrench 64 to approach the locking nut of the old tire. When the electric wrench 64 contacts the locking nut, the disassembly telescopic rod 62 stops and the electric wrench 64 disassembles the locking nut. After the locking nut is disassembled, the horizontal telescopic rod 8 is started and drives the horizontal plate 2 to move. The three-jaw chuck 6 on the other side of the connecting seat 5 is coaxially set with the tire axle.

[0034] like Figures 1-4As shown, the top wall of the transverse plate 2 is symmetrically and fixedly connected with a movable telescopic rod 21. The telescopic end of the movable telescopic rod 21 is fixedly connected to the side wall of the moving plate 3. The movable telescopic rod 21 is initially in a retracted state. When it is necessary to remove the old tire, the movable telescopic rod 21 is activated, which drives the moving plate 3 to approach the old tire. After the old tire is removed, the movable telescopic rod 21 is reset. When the three-jaw chuck 6 on the other side of the connecting seat 5 is coaxial with the tire axle, and a new tire needs to be replaced, the movable telescopic rod 21 is activated, which drives the three-jaw chuck 6 holding the new tire to approach the axle and install the new tire on the axle. The second switch 717 is electrically connected to the transverse telescopic rod 8 and the movable telescopic rod 21.

[0035] Using a jack to lift the landing gear, the trolley frame 1 is moved to the vicinity of the old tire on the landing gear. The trolley frame 1 moves the three-jaw chuck 6 on one side of the connecting seat 5 closer to the old tire, and moves the new tire closer to the three-jaw chuck 6 on the other side of the connecting seat 5. The lifting telescopic rod 11 is activated, which moves the trolley frame 1 away from the ground and also moves the three-jaw chuck 6 on one side of the connecting seat 5 to be closer to the coaxiality of the old tire. When the caster wheels are away from the ground, the lifting telescopic rod 11 stops.

[0036] When the telescopic rod 21 is activated, it moves the moving plate 3 closer to the old tire. At this time, the three-jaw chuck 6 on one side of the connecting seat 5 approaches the old tire, and the three-jaw chuck 6 on the other side of the connecting seat 5 approaches the new tire. The air pump 7 inputs airflow into the detection tube 71. The high-pressure airflow moves the guide plate 713 close to the top wall of the detection tube 71 on the guide post 712, compressing the spring 714. At this time, the guide plate 713 will not contact the second switch 717. Simultaneously, the high-pressure airflow enters the first telescopic rod 715, which activates and drives the first switch 716 to contact the sealing ring 711, inputting the high-pressure airflow into... Inside the pneumatic box 61, the pneumatic impeller 65 is driven to rotate, which in turn drives the three-jaw chucks 6 on both sides of the connecting seat 5 to fix the old tire and the new tire respectively. When the three-jaw chuck 6 fixes the old tire, the old tire will not move because it is connected to the landing gear. The three-jaw chuck 6 drives the guide rod 51 to move on the transverse box 4 through the connecting seat 5, adjusting the longitudinal position of the three-jaw chuck 6 and the old tire. At this time, the guide spring 52 deforms according to the adjustment state. At the same time, the three-jaw chuck 6 drives the transverse box 4 to move on the moving plate 3 through the connecting seat 5 and the guide rod 51, adjusting the transverse position of the three-jaw chuck 6 and the old tire.

[0037] When the three-jaw chucks 6 on both sides of the connecting seat 5 fix the old tire and the new tire respectively, the airflow cannot drive the pneumatic impeller 65 to rotate. The air pressure in the pneumatic box 61 gradually increases, and the air pressure on both sides of the guide plate 713 gradually tends to be balanced, which drives the spring 714 to reset. The spring 714 drives the guide plate 713 to move, which drives the guide plate 713 to cooperate with the sealing ring 711. The first telescopic rod 715 drives the first switch 716 to contact the sealing ring 711. The guide plate 713 contacts the first switch 716, and the air pump 7 stops inputting airflow into the detection tube 71.

[0038] When the guide plate 713 contacts the first switch 716, the first electromagnet 41 and the guide rod 51 are magnetically attracted, the first electromagnet 41 fixes the guide rod 51, the guide rod 51 is locked, and the longitudinal position of the three-jaw chuck 6 is locked. The second electromagnet 42 and the moving plate 3 are magnetically attracted, the second electromagnet 42 fixes the moving plate 3, the transverse box 4 is locked, and the transverse position of the three-jaw chuck 6 is locked.

[0039] When the guide plate 713 contacts the first switch 716, the disassembly telescopic rod 62 is started. The disassembly telescopic rod 62 drives the electric wrench 64 to engage with the locking nut. Then the disassembly telescopic rod 62 stops, and then the electric wrench 64 rotates to remove the locking nut. When the locking nut is completely removed, the electric wrench 64 stops, and the disassembly telescopic rod 62 drives the electric wrench 64 to reset.

[0040] When the electric wrench 64 stops, the movable telescopic rod 21 starts, driving the movable plate 3 to reset. At the same time, the transverse telescopic rod 8 starts, driving the transverse plate 2 to move, causing the three-jaw chuck 6 on the other side of the connecting seat 5 to be coaxial with the wheel axle of the tire.

[0041] The disassembly telescopic rod 62 on the other side of the connecting seat 5 is activated. The disassembly telescopic rod 62 drives the electric wrench 64 to engage with the locking nut. Then the disassembly telescopic rod 62 stops, the electric wrench 64 rotates, and the locking nut is connected to the wheel axle. After the locking nut is installed, the electric wrench 64 stops rotating, the new tire is installed on the landing gear, and the disassembly telescopic rod 62 drives the electric wrench 64 to reset.

[0042] After the old and new tires are replaced, the air pump 7 reverses the air to draw air from the detection tube 71. The airflow drives the guide plate 713 to approach the bottom wall of the detection tube 71 on the guide post 712, stretching and driving the spring 714. At the same time, it draws air from the first telescopic rod 715 and the second telescopic rod 718. The first telescopic rod 715 drives the first switch 716 to reset, and the second telescopic rod 718 drives the second switch 717 to approach the sealing ring 711.

[0043] Air is drawn from the pneumatic box 61, causing the pneumatic impeller 65 to rotate in the opposite direction. This causes the three-jaw chucks 6 on both sides of the connecting seat 5 to loosen. When the three-jaw chucks 6 on both sides of the connecting seat 5 reach their limit, they can no longer move. The airflow cannot drive the pneumatic impeller 65 to rotate, and the air pressure in the pneumatic box 61 gradually decreases. The air pressure on both sides of the guide plate 713 gradually tends to balance, causing the spring 714 to reset. The spring 714 then moves the guide plate 713, causing the guide plate 713 to engage with the sealing ring 711. The guide plate 713 then contacts the second switch 717, stopping the air pump 7. The horizontal telescopic rod 8 resets, causing the horizontal plate 2 to reset. At the same time, the lifting telescopic rod 11 resets, causing the trolley frame 1 to reset. The trolley frame 1 moves away from the landing gear, and the jack resets the landing gear. The second telescopic rod 718 resets the second switch 717.

[0044] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
