Description

Technical Field

[0001] The present invention belongs to the field of aircraft maintenance, and specifically relates to an aircraft tire and wheel hub separation device. Background Art

[0002] In the field of aviation maintenance, the maintenance of aircraft tires is a frequent and important task, which directly affects the driving safety of aircraft.

[0003] When performing maintenance and replacement on the tires of common civilian aircraft such as the Boeing series: Boeing 737-700, 737-800, etc., it is necessary to separate the wheel hub from the tire body in order to inspect the surface of the wheel hub and the inside of the tire body. When disassembling and separating the tire and wheel hub of existing common civilian aircraft such as Boeing series aircraft, usually the entire tire is first disassembled, and then the tire is deflated. At this time, the air in the tire becomes less, and a gap is generated between the tire and the wheel hub. Subsequently, manual labor uses a wrench to remove the connecting screws between the upper wheel hub and the lower wheel hub. At this time, the separation between the wheel hub and the tire occurs. Subsequently, pressure is applied to the wheel hub or the tire, and the wheel hub and the tire can be separated. With the development of the aviation industry, the requirements for aircraft maintenance equipment are getting higher and higher. Automated and intelligent maintenance equipment has gradually become the industry trend. These equipment not only improve work efficiency but also significantly reduce safety hazards caused by human factors. However, in terms of separating the aircraft tire and wheel hub, the manual disassembly method is still used, that is, manual labor uses special tools to disassemble the tire and the wheel hub one by one. Although this method has a low cost, it takes a long time and is not conducive to the rapid maintenance and preparation of aircraft tires.

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0020] As Figures 1 to 4 shown, a device for separating an aircraft tire wheel hub according to an embodiment of the present invention includes a base 1; a support plate 12 is fixedly connected to the side wall of the base 1; an adjusting plate 13 is slidably connected to the middle of the support plate 12; a first electric cylinder 14 is fixedly connected to the top of the support plate 12; the bottom end of the first electric cylinder 14 is fixedly connected to the top of the adjusting plate 13; a pair of mounting blocks 15 are installed in the middle of the adjusting plate 13; a thrust rod 16 is slidably connected to the middle of the mounting block 15; a second electric cylinder 17 is fixedly connected to the side wall of the mounting block 15; the other end of the second electric cylinder 17 is fixedly connected to the end of the thrust rod 16; a pair of tire clamping plates 18 are fixedly connected to the middle of the thrust rod 16; a wheel hub limiting component is installed in the middle of the support plate 12; during operation, part of the gas in the tire is released, and then the wheel hub is supported and limited by the wheel hub limiting component. By operating the first electric cylinder 14, the two tire clamping plates 18 can be driven to rise and fall. By operating the second electric cylinder 17, the thrust rod 16 and the tire clamping plates 18 can be driven to move horizontally. With the coordinated operation of the first electric cylinder 14 and the second electric cylinder 17, the two tire clamping plates 18 are respectively moved to both sides of the tire carcass, and then the second electric cylinder 17 is operated to drive the tire clamping plates 18 to move. During the process of the tire carcass being extruded and moved by the tire clamping plates 18, the wheel hub is difficult to move due to the wheel hub limiting component. Therefore, under the continuous force of the tire carcass, the tire carcass is separated from the wheel hub. Through the above structure, the tire installed at a specified position can be automatically separated from the wheel hub and the tire carcass, improving the separation speed of the wheel hub and the tire carcass, reducing the waste of human resources, and at the same time reducing the safety risks brought by manual operation.

[0021] As Figures 1 to 7As shown in the figure, the hub limit assembly includes a support shaft 2; the support shaft 2 is fixedly connected to the middle of the support plate 12; a support rod 21 is slidably connected to the middle of the support shaft 2; a third electric cylinder 22 is fixedly connected to the side wall of the support plate 12; a connector 23 is fixedly connected to the end of the third electric cylinder 22; a circular plate 24 is fixedly connected to the end of the support rod 21; the circular plate 24 is fixedly connected to the middle of the connector 23; a pair of limit blocks 25 are symmetrically arranged and rotatably connected to the middle of the support rod 21 through torsion springs; a pull rope 26 is fixedly connected to the middle of the limit block 25; a fourth electric cylinder 27 is fixedly connected to the inside of the support rod 21; a first connecting rod 28 is fixedly connected to the end of the fourth electric cylinder 27 close to the limit block 25; the other ends of the pair of pull ropes 26 are fixedly connected to the middle of the first connecting rod 28; during operation, the third electric cylinder 22 can be started according to the width of the tire to drive the support rod 21 to move, adjust the limit block 25 to a suitable position, then sleeved the central hole of the tire hub on the support rod 21 and the support shaft 2. After the hub is completely sleeved, the limit block 25 will rotate and extend out of the middle of the support rod 21 under the elastic force of the torsion spring, so that the hub is blocked. After the separation of the hub and the tire body is completed, the fourth electric cylinder 27 is started to drive the first connecting rod 28 to move and pull the pair of pull ropes 26 to make the pair of limit blocks 25 retract into the support rod 21, so as to release the limit on the hub, so that the hub can be removed. Through the above structure, the hubs of different widths can be limited and supported, and after the separation of the hub and the tire body is completed, the limit effect on the hub can be conveniently released, so that the hub can be quickly removed, improving the convenience of using the device.

[0022] As Figures 1 to 3 shown, an installation groove 3 is opened at the top of the base 1; a motor 31 is fixedly connected to the side wall of the installation groove 3; an output end of the motor 31 is fixedly connected to a first gear 32; a bidirectional screw rod 33 is rotatably connected to the middle of the installation groove 3; a pair of carrier rods 34 are symmetrically arranged and threadedly connected to the middle of the bidirectional screw rod 33; a second gear 35 is fixedly connected to the middle of the bidirectional screw rod 33; the second gear 35 is meshed with the first gear 32; a fixed guide rod 36 is fixedly connected to the middle of the installation groove 3; the other ends of the pair of carrier rods 34 are slidably connected to the middle of the fixed guide rod 36; during operation, the tire can be rolled along the inclined surfaces on both sides of the base 1 onto the pair of carrier rods 34 and supported by the pair of carrier rods 34. Then, according to the diameter of the tire and the height of the hub shaft hole, the motor 31 is started to drive the bidirectional screw rod 33 to rotate, so that the pair of carrier rods 34 approach each other. Since the tire is tangent to the pair of carrier rods 34 on the pair of carrier rods 34, the approach of the pair of carrier rods 34 will cause the hub shaft hole to move upward, so that the hub shaft hole is aligned with the end of the support rod 21, and then the tire can be slid to quickly complete the support and limit of the hub. Through the above structure, the hubs of different diameter tires can be conveniently installed on the support rod 21 without the need for personnel to lift the tire, further improving the convenience of using the device.

[0023] As Figure 4As shown in the figure, a pair of sliding grooves 4 are symmetrically arranged in the middle of the adjusting plate 13; a pair of mounting blocks 15 are respectively slidably connected to the middle of the pair of sliding grooves 4; a pair of fifth electric cylinders 41 are fixedly connected to the top of the adjusting plate 13; the other end of the fifth electric cylinder 41 is fixedly connected to the side wall of the mounting block 15; during operation, a pair of fifth electric cylinders 41 can be started according to the diameter of the wheel hub and the diameter of the tire carcass to drive a pair of mounting blocks 15 to slide along the sliding grooves 4 and approach or move away from each other, so as to adjust the distance between the two tire clamping plates 18, so that the two tire clamping plates 18 can extrude and peel off tire carcasses of different diameters, and reduce the possibility of the tire clamping plates 18 contacting the wheel hub. Through the above structure, tire carcasses of different diameters can be separated, and the situation of the wheel hub being damaged by the extrusion of the tire clamping plates 18 can be reduced.

[0024] As Figure 7 shown, a groove 5 is provided in the middle of the limiting block 25; a pair of pulleys 51 are rotatably connected to the middle of the support rod 21; the pull rope 26 is arranged around the middle of the pulley 51; during operation, when the pull rope 26 moves, the arrangement of the groove 5 and the pulley 51 can reduce the contact between the middle of the pull rope 26 and the limiting block 25 or the support rod 21, thereby reducing the situation of the pull rope 26 being worn and broken. Through the above structure, the situation of the pull rope 26 being worn and broken can be reduced, and the durability of the component can be improved.

[0025] As Figure 2 shown, the middle of the bearing rod 34 is rotatably and slidably connected with an adjusting pipe 6; the inner surface of the adjusting pipe 6 is made of smooth metal material, and the outer surface is made of rubber material; during operation, when the tire is pushed onto the pair of bearing rods 34, the tire falls on the pair of adjusting pipes 6, so that when the height of the wheel hub needs to be adjusted and the tire needs to slide towards the support rod 21, the tire carcass does not directly generate sliding friction with the bearing rod 34, reducing the moving resistance of the tire. Through the above structure, when the tire slides on the bearing rod 34, the situation of the tire carcass directly contacting the support plate 12 and generating a large amount of friction, resulting in difficult sliding, is reduced, making the use of the device more labor-saving and improving the convenience of use of the device.

[0026] As Figure 2 shown, a rotating ring 7 is rotatably connected to the side wall of the adjusting pipe 6; a telescopic rod 71 is fixedly connected between the pair of rotating rings 7; the arrangement of the rotating ring 7 and the telescopic rod 71 will keep the positions of the pair of adjusting pipes 6 on their respective bearing rods 34 always consistent, so that it is not necessary to separately adjust the position of one adjusting pipe 6 before rolling the tire onto the pair of adjusting pipes 6. Through the above structure, it is not necessary to separately adjust the position of each adjusting pipe 6 before rolling the tire onto the pair of adjusting pipes 6, improving the convenience of use of the device.

[0027] As Figure 2As shown in the figure, a collection box 8 is slidably installed at the bottom of the support shaft 2; a handle 81 is fixedly connected to the side wall of the collection box 8; during the process of separating the tire carcass, the carcass will be deformed by force, and some of the dried mud attached to the surface of the carcass will be crushed under pressure and fall into the collection box 8. After the use of the device is completed, the collection box 8 can be conveniently taken out to clean the mud. Through the above structure, the mud falling from the carcass can be collected, and it is convenient to centrally process the collected mud, reducing the pollution of the working environment by the mud.

[0028] During operation, the hub limiting component is used to support and limit the hub. The operation of the first electric cylinder 14 can drive the two sets of tire clamping plates 18 to rise and fall. The operation of the second electric cylinder 17 can drive the ejector rod 16 and the tire clamping plates 18 to move horizontally. By the coordinated operation of the first electric cylinder 14 and the second electric cylinder 17, the two sets of tire clamping plates 18 are respectively moved to both sides of the tire carcass. Then, by the operation of the second electric cylinder 17 to drive the tire clamping plates 18 to move, during the process of the tire carcass being squeezed and moved by the tire clamping plates 18, the hub is difficult to move due to the hub limiting component. Thus, under the continuous force on the tire carcass, the tire carcass is separated from the hub. The third electric cylinder 22 can be started according to the width of the tire to drive the support rod 21 to move, and the limiting block 25 is adjusted to a suitable position. Then, the central hole of the tire hub is sleeved on the support rod 21 and the support shaft 2. After the hub is completely sleeved, the limiting block 25 will rotate under the elastic force of the torsion spring and extend out of the middle of the support rod 21, blocking the hub. After the separation of the hub and the tire carcass is completed, the fourth electric cylinder 27 is started to drive the first connecting rod 28 to move and pull a pair of pull ropes 26, causing a pair of limiting blocks 25 to retract into the support rod 21, thus releasing the limit on the hub and enabling the hub to be removed. The tire can be rolled along the inclined surfaces on both sides of the base 1 onto a pair of bearing rods 34 for support. Then, according to the diameter of the tire and the height of the hub shaft hole, the motor 31 is started to drive the bidirectional screw 33 to rotate, causing the pair of bearing rods 34 to approach each other. Since the tire is in a tangential state with the pair of bearing rods 34 on the pair of bearing rods 34, the approach of the pair of bearing rods 34 will cause the hub shaft hole to move upward, thus aligning the hub shaft hole with the end of the support rod 21. Then, by sliding the tire, the support and limit of the hub can be quickly completed. The pair of fifth electric cylinders 41 can be started according to the diameter of the hub and the diameter of the tire carcass to drive a pair of mounting blocks 15 to slide along the chute 4 and approach or move away from each other, thereby adjusting the distance between the two sets of tire clamping plates 18, enabling the two sets of tire clamping plates 18 to squeeze and peel different-diameter tire carcasses and reducing the possibility of contact between the tire clamping plates 18 and the hub. When the pull rope 26 moves, the arrangement of the groove 5 and the pulley 51 can reduce the contact between the middle of the pull rope 26 and the limiting block 25 or the support rod 21, thereby reducing the occurrence of the pull rope 26 being worn and broken. When the tire is pushed onto the pair of bearing rods 34, the tire lands on a pair of adjusting tubes 6. Thus, when the height of the hub is adjusted and the tire needs to be slid towards the support rod 21, the tire carcass does not directly generate sliding friction with the bearing rod 34, reducing the moving resistance of the tire. The arrangement of the rotating ring 7 and the telescopic rod 71 will keep the positions of the pair of adjusting tubes 6 on their respective bearing rods 34 consistent all the time, so that it is not necessary to adjust the positions of the pair of adjusting tubes 6 before rolling the tire onto the pair of adjusting tubes 6. During the separation process of the tire carcass, the tire carcass will be deformed by force, and some dry and solid mud stains attached to the surface of the tire carcass will be crushed under pressure and fall into the collection box 8. After the use of the device is completed,The collection box 8 can be conveniently taken out for cleaning the mud and dirt.
