Description

Technical Field

[0001] The invention relates to the technical field of tire maintenance devices, and more specifically, to a wheel disassembly and assembly auxiliary device for civil aircraft maintenance. Background Art

[0002] The main landing gear wheel system of modern civil airliners is composed of multiple components such as wheel hubs, tires, brake devices, bearing assemblies, and retraction and extension mechanisms. Among them, the brake hub, as the core brake component, is usually cast from high-strength alloy steel. Since the brakes are often used to slow down during aircraft landing, the brake hub is prone to wear. Therefore, in daily aircraft maintenance, the brake hub needs to be replaced frequently. When people disassemble and decompose the wheel assembly, they often need to remove the two half-hubs from the wheel hub and disassemble and inspect components such as the half-hubs or brake hubs.

[0016] 1. In the present invention, the angle of the aircraft wheel is rotated and lifted by the cooperation of the auxiliary part and the driving part. The first lifting function is to support the aircraft tire up and down to adjust the position by the cooperation of the auxiliary part and the driving part. The lifting function can lift the aircraft tire upward during the disassembly process so that its gravity cannot act on the fixing bolt, which can facilitate the user to remove the aircraft tire. The second is the rotation process during the lifting process.

An auxiliary mechanism is arranged in the arc plate, and rolling friction occurs between the circumferential surface of the aircraft wheel and the movable roller and the driving roller in the auxiliary mechanism. In this way, the aircraft wheel is not only more labor-saving when lifting and lowering, but also the rotation adjustment of the wheel can be realized.

[0018] 3. In the present invention, the installation space is saved by the auxiliary components, and the movable roller and the driving roller are driven to rotate by a single set of driving parts, which not only reduces the use cost, but also has a simple structure and is easy to operate.

At this time, the telescopic rod at the bottom end of the horizontal support plate is synchronously extended, so the auxiliary block at the bottom end of the telescopic rod will not move due to the upward movement of the horizontal support plate. When the horizontal support plate rotates, the limit block on the limit plate is slidably connected in the annular groove. Therefore, when the adjustment mechanism is in use, there will be no motion interference and it has better stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1 of the present invention further describes a wheel disassembly and assembly auxiliary device for maintenance of civil aircraft, including a traction frame body 100, a protrusion 101 is formed inwardly at the middle position of the traction frame body 100, a hydraulic jack 102 is detachably installed on the upper end surface of the protrusion 101, a support frame 103 is fixedly connected to the output end of the hydraulic jack 102, vertical support plates 104 are fixedly connected to both sides of the support frame 103, and the vertical support plates 104 on both sides are fixedly connected to the connecting plates 105, and the connecting plates 105 are fixedly connected to the horizontal direction of the cross plates 106, and the cross plates 106 on both sides are symmetrically fixedly connected to the support rods 107, and the upper end surfaces of the support rods 107 on both sides are fixedly connected to the arc plates 108, and the arc plates 108 are provided with an adjustment mechanism 200;

[0034] Since the brakes are often used to slow down during the landing process, the brake hub is easy to wear. In the daily maintenance of the aircraft, the brake hub needs to be replaced frequently. Therefore, when people disassemble and disassemble the wheel assembly, they often need to remove the two half-hubs from the wheel hub, and then complete the "tire" removal work. Finally, the half-hubs or brake hubs and other components need to be disassembled and inspected. During this process, people need to roll and lift the wheel to complete the disassembly and inspection of the wheel. The tool for replacing the brake hub used in airline maintenance currently uses a screw to lift the brake hub, which is actually more laborious to use, and there is no structure for adjusting the rotation alignment of the wheel, so the efficiency is low;

[0035] The invention can adjust the height of the curved plate 108 in the vertical direction by lifting and lowering the hydraulic jack 102, so as to adjust the height of the aircraft wheel from the ground, so that the aircraft wheel can be aligned with the aircraft wheel axle by adjusting the height from the ground during the disassembly and assembly process, and the aircraft wheel can be easily disassembled and assembled. In this way, the structure is simple, the operation is convenient, the stability is good, and the amount of later maintenance is small. The curved plate 108 is provided with an auxiliary mechanism 300, and rolling friction occurs between the circumferential surface of the aircraft wheel and the movable roller 301b and the driving roller 301c in the auxiliary mechanism 300. In this way, the aircraft wheel is not only more labor-saving when lifting and lowering, but also can realize the rotation adjustment of the wheel. In addition, universal wheels are provided at both ends of the traction frame body 100, and the movement efficiency is better.

[0036] The adjusting mechanism 200 includes a supporting member 201 provided in the horizontal plate 106, an auxiliary member 202 is provided at the bottom end of the arc plate 108, a driving member 203 cooperating with the auxiliary member 202 is provided in the supporting member 201, and the auxiliary member 202 and the driving member 203 cooperate to adjust the angle of the wheel, and also includes an auxiliary mechanism 300, the auxiliary mechanism 300 includes a movable member 301 provided in the arc plate 108, a gear member 302 is further provided in the arc plate 108, and a linkage member 303 is provided at the bottom end of the arc plate 108, and the linkage member 303 cooperates with the gear member 302 to control the movable member 301;

[0037] Depend on Figures 1 to 8 It can be seen that the auxiliary member 202 and the driving member 203 cooperate to adjust the wheel angle to rotate and lift. The first is the lifting function; the auxiliary member 202 and the driving member 203 cooperate to support the aircraft tire to move up and down to adjust the position. The lifting function can lift the aircraft tire upward during the disassembly process so that its gravity cannot act on the fixing bolts, which can facilitate the user to remove the aircraft tire. During the installation process, the height of the aircraft tire can be adjusted to quickly align the mounting hole of the wheel hub with the fixing bolts for installation, saving time and effort. The second is the rotation process during the lifting process. When the aircraft tire continues to move upward, the aircraft tire rotates due to the cooperation of the groove structure inside the adjustment mechanism 200, which is convenient for the staff to quickly repair the state of the aircraft wheel.

[0038] Meanwhile, the present invention is provided with an auxiliary component, which controls the movable member 301 by cooperating with the linkage member 303 and the gear member 302. Compared with the adjusting mechanism 200, the auxiliary component adds the adjustment function of the aircraft wheel in the initial state. The circumferential surface of the aircraft wheel and the movable roller 301b and the driving roller 301c in the auxiliary mechanism 300 generate rolling friction, so that the aircraft wheel is not only more labor-saving when lifting and lowering, but also can achieve the adjustment of the wheel. The auxiliary component saves installation space, and the movable roller 301b and the driving roller 301c are driven to rotate by a single set of driving members 203, which not only reduces the use cost, but also has a simple structure and is easy to operate, and can achieve the adjustment of the aircraft wheel.

[0039] Working principle: When in use, the staff drives the whole device to move to the working area through the traction frame body 100, and adjusts the height of the arc plate 108 in the vertical direction by lifting and lowering the hydraulic jack 102, so that the arc plate 108 contacts the bottom end of the wheel. When the wheel needs to be repaired, it is only necessary to control the movable part 301 through the linkage part 303 and the gear part 302, and the rolling friction between the circumferential surface of the aircraft wheel and the movable roller 301b and the driving roller 301c in the auxiliary mechanism 300 is generated, so as to realize the rotation of the wheel, and the operation is relatively convenient. When it is necessary to adjust the height of the aircraft tire so that the mounting hole of the wheel hub is quickly aligned with the fixing bolt, it is only necessary to adjust the wheel in the vertical direction through the auxiliary part 202 and the driving part 203. After the installation is completed, it can continue to be lifted by the hydraulic jack 201c to realize the rotation of the wheel. In this way, it can adapt to the maintenance personnel under different conditions, and the operation is convenient, the stability is good, and the later maintenance is small.

[0040] Embodiment 2

[0041] The following technical features are added on the basis of the first embodiment: the adjustment mechanism 200 includes a support member 201 arranged in the horizontal plate 106, an auxiliary member 202 is arranged at the bottom end of the arc plate 108, a driving member 203 cooperating with the auxiliary member 202 is arranged in the support member 201, the auxiliary member 202 and the driving member 203 cooperate to adjust the angle of the wheel, the support member 201 includes an arc strip 201a fixed between two groups of horizontal plates 106, a connecting plate 201b is fixedly connected between the arc strips 201a on both sides, and a hydraulic jack 2 201c is detachably installed on the upper end surface of the connecting plate 201b;

[0042] Depend on Figures 1 to 6 It can be seen that the driving force for the arc plate 108 to rise is controlled by the hydraulic jack 201c, which is installed in the middle of the connecting plate 201b to ensure the overall stability of the device. When in use, the auxiliary member 202 and the driving member 203 cooperate to rotate and lift the wheel angle, and the auxiliary member 202 and the driving member 203 cooperate to support the aircraft tire to move up and down to adjust the position. During the disassembly process, the lifting function can lift the aircraft tire upward so that its gravity cannot act on the fixing bolts, which can facilitate the user to remove the aircraft tire. During the installation process, the height of the aircraft tire can be adjusted to quickly align the mounting hole of the wheel hub with the fixing bolts for installation, which saves time and effort. When the aircraft tire continues to move upward, the aircraft tire rotates due to the cooperation of the internal groove structure of the adjustment mechanism 200, which is convenient for the staff to quickly repair the state of the aircraft wheel.

[0043] The auxiliary member 202 includes an inclined plate 202a fixedly connected to both sides of the bottom end of the arc-shaped plate 108, an auxiliary plate 202b is fixedly connected between the inclined plates 202a on both sides, an auxiliary groove 202c is provided at the center of the auxiliary plate 202b, an auxiliary block 202d is rotatably connected in the auxiliary groove 202c, a telescopic rod 202e is fixedly connected to the upper end surface of the auxiliary block 202d, a horizontal support plate 202f is fixedly connected to the upper end surface of the telescopic rod 202e, a hollow hole 202g is correspondingly provided at the middle position of the arc-shaped plate 108, the horizontal support plate 202f is correspondingly provided in the hollow hole 202g, a corresponding clamping groove 202h is provided in the auxiliary groove 202c, a corresponding clamping ring 202i is provided on the outer wall of the auxiliary block 202d, and the clamping ring 202i is correspondingly provided in the clamping groove 202h;

[0044] Depend on Figures 4 to 8It can be seen that the bottom end of the arc-shaped plate 108 is symmetrically fixedly connected with an inclined plate 202a, a circular auxiliary plate 202b is fixedly connected between the two groups of inclined plates 202a, an auxiliary block 202d is rotatably connected to the center position of the auxiliary plate 202b, and the rotation effect of the auxiliary block 202d is controlled by the hydraulic jack 201c, and the upper end surface of the auxiliary block 202d is fixedly connected with a telescopic rod 202e, and the upper end surface of the telescopic rod 202e is fixedly connected with a horizontal support plate 202f, and the wheel is placed above the horizontal support plate 202f. For the stability of the auxiliary block 202d, a snap ring 202i is formed on the outer wall of the auxiliary block 202d, and the snap ring 202i is correspondingly arranged in the card slot 202h, so as to ensure the stability of the rotation of the auxiliary block 202d;

[0045] The driving member 203 includes a positioning block 203a integrally formed at the top of the second hydraulic jack 201c, a positioning groove 203b is correspondingly provided in the auxiliary block 202d, the positioning groove 203b is recessed inward to form a straight groove 203c, the straight groove 203c extends upward to form an arc groove 203d, the positioning block 203a is correspondingly slidably connected in the straight groove 203c and the arc groove 203d, the two sides of the output end of the second hydraulic jack are fixedly connected to the limiting plate 203e, the upper end surface of the limiting plate 203e is fixedly connected to the limiting block 203f, the bottom end of the horizontal support plate 202f is provided with an annular groove 203g, and the limiting block 203f is correspondingly slidably connected in the annular groove 203g;

[0046] Depend on Figures 4 to 8 It can be seen that a cylindrical positioning groove 203b is formed in the auxiliary block 202d, and a straight groove 203c in the vertical direction is formed in the positioning groove 203b. The straight groove 203c extends upward to form an arc groove 203d. The positioning block 203a is correspondingly slidably connected in the straight groove 203c and the arc groove 203d. Since the position of the auxiliary block 202d is stuck in the auxiliary plate 202b, the auxiliary block 202d will not move in the vertical direction. When the positioning block 203a slides The auxiliary block 202d does not rotate when the positioning block 203a is slidably connected to the arc groove 203d. Since the hydraulic jack 2 drives the positioning block 203a to move only in the vertical direction, when the positioning block 203a contacts the arc groove 203d, the deflection force of the arc groove 203d drives the auxiliary block 202d to rotate. When the auxiliary block 202d rotates, it drives the horizontal support plate 202f on the telescopic rod 202e to rotate synchronously.

[0047] Working principle: As can be seen from Example 1, when the wheel needs to be moved in the vertical direction, the horizontal support plate 202f is driven to move in the vertical direction by the second hydraulic jack 201c. Since the positioning block 203a is slidably connected in the straight groove 203c, the auxiliary block 202d will not rotate at this time. When the horizontal support plate 202f supports the aircraft tire to move up and down to adjust the position, its lifting function can lift the aircraft tire upward during the disassembly process so that its gravity cannot act on the fixing bolt, which can facilitate the user to remove the aircraft tire. During the installation process, the height of the aircraft tire can be adjusted to quickly align the mounting hole of the wheel hub with the fixing bolt for installation, which saves time and effort. When the rotation direction of the aircraft wheel needs to be adjusted;

[0048] As the second hydraulic jack 201c drives the positioning block 203a to continue to move upward, the positioning block 203a enters the arc groove 203d from the straight groove 203c. Since the position of the auxiliary block 202d is stuck in the auxiliary plate 202b, the auxiliary block 202d will not move in the vertical direction. When the positioning block 203a is slidably connected in the straight groove 203c, the auxiliary block 202d will not rotate. When the positioning block 203a is slidably connected in the arc groove 203d, the deflection force of the arc groove 203d drives the auxiliary block 202d to rotate. When the auxiliary block 202d rotates, it drives the horizontal support plate 202f on the telescopic rod 202e to rotate synchronously, thereby synchronously driving the upper wheel to rotate, which is convenient for the staff to carry out rapid maintenance.

[0049] When the device is in use, when the hydraulic jack 201c drives the positioning block 203a to move in the vertical direction, the limit plates 203e are fixedly connected on both sides of the hydraulic jack 201c, and the limit plates 203e drive the horizontal support plate 202f to move upward. At this time, the telescopic rod 202e at the bottom end of the horizontal support plate 202f is extended synchronously, so the auxiliary block 202d at the bottom end of the telescopic rod 202e will not move due to the upward movement of the horizontal support plate 202f. When the horizontal support plate 202f rotates, the limit block 203f on the limit plate 203e is slidably connected in the annular groove 203g. Therefore, when the adjusting mechanism 200 is in use, there will be no motion interference and it has better stability.
