Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, specifically to a ground-rail type fuselage dock and dock system. Background Technology

[0002] Currently, aircraft rely on docking stations for painting, maintenance, and other operations, which allows operators to perform these tasks on various parts of the aircraft.

[0003] Current aircraft dock systems, especially fuselage docks, are typically not liftable or movable, making them unsuitable for different aircraft models. To address this issue, the current solution is to use a suspended lifting platform mounted on the roof of a building. However, this method places high demands on the hangar's spatial layout and load-bearing capacity, significantly increasing infrastructure costs. After the aircraft is moved into the hangar and positioned, the suspended lifting platform is then raised, lowered, and moved to a suitable location for subsequent maintenance. However, this approach requires minimizing the weight of the fuselage dock due to the limited load-bearing capacity of the lifting equipment. While reducing the number of guardrails and the thickness of the base plate can reduce the weight of the fuselage dock, this can also decrease its overall strength and compromise safety.

[0004] Therefore, this application proposes a ground-rail type fuselage dock and dock system to solve at least one of the above-mentioned problems, and thus this application is made. Utility Model Content

[0005] The purpose of this application is to provide a ground-rail type fuselage dock and dock system to solve the problems of high weight requirements for fuselage docks and easy impact on operator safety in the prior art.

The upper worktable and the two lower fixed platforms are fixedly connected to the supporting connecting beam, and the two lower movable platforms are slidably connected to the supporting connecting beam along its axial direction. The two lower activity platforms can be either close to each other or far apart; The bottom of both support columns is provided with a slide rail structure that is arranged horizontally and perpendicular to the axial direction of the support connecting beam.

[0007] Optionally, the bottom of the upper worktable is provided with a plurality of upper sliding frames, which are slidably connected to the upper worktable; It also includes an upper shelf zipper, one end of which is connected to the upper slide-out frame located at the end of the upper worktable, and the other end is fixedly connected to the end of the upper worktable.

[0008] Optionally, the bottom of the lower movable platform is provided with a plurality of lower sliding frames, which are slidably connected to the lower movable platform; It also includes a lower shelf zipper, one end of which is connected to the lower slide-out shelf located at the end of the lower movable platform, and the other end is fixedly connected to the end of the lower movable platform near the lower fixed platform.

[0009] Optionally, it also includes a sliding cage fitted onto and slidably connected to the support column; The supporting connecting beam is fixedly connected to the sliding cage, and the supporting connecting beam is movably connected to the supporting column through the sliding cage.

[0010] Optionally, the drive assembly includes a drive motor, a mounting bracket, a motor transmission rod, a transmission worm gear, and a lifting worm gear, wherein: The mounting frame is fixedly connected to the sliding cage; The output shaft of the drive motor is connected to a horizontally arranged motor transmission rod, which is connected to two horizontally arranged transmission worms. The axes of the two transmission worms are perpendicular to the axis of the motor transmission rod. There are two lifting worms located on both sides of the support column. The two transmission worms are connected to the two lifting worms respectively. The two lifting worms are inserted into the mounting frame and threadedly connected to it.

[0011] Optionally, a fall arrestor structure may also be provided on the supporting connecting beam or the sliding cage; The support column is equipped with a groove or baffle that is compatible with the fall protection structure.

[0012] Optionally, the supporting connecting beam includes a fixedly connected upper beam and two lower beams; The supporting connecting beam forms an H-shaped frame structure with the two supporting columns through the upper beam part; There is a gap between the two lower beams; The upper workbench is fixed to the upper beam. The two lower fixed platforms are fixed to the lower beam. The bottoms of the two lower movable platforms are movably connected to the two lower fixed platforms, and the tops of the two lower movable platforms are movably connected to the bottom of the upper worktable.

[0013] Optionally, the bottom of the lower movable platform is provided with pulleys, and the two lower movable platforms are movably connected to the two lower fixed platforms through the pulleys; The lower movable platform includes an inclined section and a horizontal section.

The two lower movable platforms can move closer or further apart, ensuring that the two movable lower platforms do not interfere with the aircraft wings as the ground-rail fuselage dock approaches the aircraft fuselage. When the ground-rail fuselage dock approaches the aircraft, the two movable lower platforms are positioned directly above the wing roots for maintenance and painting of the fuselage area near the wings. Because this ground-rail fuselage dock is directly set on the ground, its overall structural design does not require excessive consideration of weight, allowing for more flexible selection of structural components. Compared to existing technologies, this effectively solves the problems of high weight requirements and potential safety hazards to operators associated with existing fuselage docks.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1: like Figures 1 to 3 As shown, this embodiment provides a ground-rail type fuselage dock, including a supporting connecting beam 2 and two supporting columns 1, wherein the supporting connecting beam 2 is movably connected to the two supporting columns 1 along the vertical direction; It also includes a drive assembly for driving the support connecting beam 2 to move vertically up and down on the two support columns 1; The supporting connecting beam 2 is provided with an upper worktable 31, two lower movable platforms 32, and two lower fixed platforms 33. The upper worktable 31 and the two lower fixed platforms 33 are all fixedly connected to the supporting connecting beam 2, and the two lower movable platforms 32 are slidably connected to the supporting connecting beam 2 along its axial direction. The two lower activity platforms 32 can be in two states: close together and far apart. The bottom of each of the two support columns 1 is provided with a slide rail structure 11 that is arranged in the horizontal direction perpendicular to the axis of the support connecting beam 2.

[0026] This embodiment abandons the traditional approach of suspending the fuselage dock in the air using hoisting equipment for maintenance and painting of the fuselage surface. Instead, it uses a sliding rail structure 11 at the bottom of the support column 1 of the ground-rail fuselage dock, along with an upper worktable 31, two lower fixed platforms 33, and two lower movable platforms 32. The two lower movable platforms 32 can move closer or further apart, ensuring that the two movable lower platforms 32 do not interfere with the wings of the aircraft 6 as the ground-rail fuselage dock approaches the fuselage. When the ground-rail fuselage dock approaches the aircraft, the two movable lower platforms 32 are positioned above the wing roots, allowing for maintenance and painting of the fuselage area near the wings. Since this ground-rail fuselage dock is directly installed on the ground, its overall structural design does not require excessive consideration of weight, allowing for more flexible selection of structural components. Compared to existing technologies, this effectively solves the problems of high weight requirements and potential safety risks to operators associated with existing fuselage docks.

[0027] In this embodiment, the bottom of the upper workbench 31 is provided with a plurality of upper slide-out frames 311, and the upper slide-out frames 311 are slidably connected to the upper workbench 31. It also includes an upper shelf zipper 312, one end of which is connected to the upper slide-out frame 311 located at the end of the upper worktable 31, and the other end is fixedly connected to the end of the upper worktable 31. In this embodiment, by setting the upper slide-out frame 311, operators can operate from a position closer to the top of the machine body. Furthermore, the upper shelf zipper 312 provides safety protection, preventing operators from accidentally stepping into a hole while walking on the upper slide-out frame 311.

[0028] In this embodiment, the bottom of the lower movable platform 32 is provided with a plurality of lower sliding frames 321, and the lower sliding frames 321 are slidably connected to the lower movable platform 32. It also includes a lower shelf zipper 322, one end of which is connected to the lower slide-out shelf 321 located at the end of the lower movable platform 32, and the other end is fixedly connected to the end of the lower movable platform 32 near the lower fixed platform 33. In this embodiment, by setting the lower slide-out shelf 321, operators can operate from a position closer to the upper part of the machine body. Furthermore, by setting the upper shelf zipper 312, a safety protection function is provided to prevent operators from accidentally stepping into a hole while walking on the lower slide-out shelf 321.

[0029] In this embodiment, a sliding cage 4 is also included, which is fitted onto the support column 1 and slidably connected thereto; The supporting connecting beam 2 is fixedly connected to the sliding cage 4, and the supporting connecting beam 2 is movably connected to the supporting column 1 through the sliding cage 4. By setting the sliding cage 4, the resistance generated by the supporting connecting beam 2 during the lifting and moving process can be reduced. In this embodiment, the sliding cage 4 includes four vertically arranged rods and two rectangular frames. The two ends of the four rods are respectively set at the corner positions of the two rectangular frames. Rollers to reduce frictional resistance are set between the sliding cage 4 and the supporting column 1.

[0030] In this embodiment, the drive assembly includes a drive motor 53, a mounting bracket 51, a motor transmission rod 54, a transmission worm gear 52, and a lifting worm gear 55, wherein: The mounting bracket 51 is fixedly connected to the sliding cage 4; The output shaft of the drive motor 53 is connected to the horizontally arranged motor transmission rod 54. The motor transmission rod 54 is connected to two horizontally arranged transmission worm gears 52. The axes of the two transmission worm gears 52 are perpendicular to the axis of the motor transmission rod 54. Two lifting worm gears 55 are provided and located on both sides of the support column 1. The two transmission worm gears 52 are connected to the two lifting worm gears 55 respectively. The two lifting worm gears 55 are inserted into the mounting bracket 51 and threadedly connected to it.

[0031] The power transmission path in this embodiment is as follows: drive motor 53, motor output shaft, motor transmission rod 54, two transmission worm gears 52, and lifting worm gear 55. The rotating lifting worm gear 55 drives the mounting frame 51 to rise and fall, thereby driving the sliding cage 4 and the supporting connecting beam 2 to rise and fall.

[0032] In this embodiment, a worm wheel is also provided between the transmission worm 52 and the lifting worm 55. The motor transmission rod 54 is also a worm, and a worm wheel is also provided between the motor transmission rod 54 and the transmission worm 52. Through the above power transmission structure, a single drive motor 53 can drive the two lifting worms 55 to rotate simultaneously, thereby making the force lifting process of the entire mounting frame 51 more stable. In some embodiments, technicians can also replace the entire transmission mechanism in this embodiment with gear transmission as needed. The worm wheel and worm gear transmission method or the gear transmission method are both common transmission methods, which will not be described in detail here.

[0033] In some embodiments, the drive component may also employ a structure such as a winch to drive the support connecting beam 2 to move up and down. For example, the winch may be placed on the top of the support column 1, and one end of the winch’s cable may be connected to the support connecting beam 2 to drive it to move up and down. Other structures may also be used by technicians to drive the support connecting beam 2 to move up and down, which will not be elaborated here.

[0034] In this embodiment, the drive motor 53 is mounted on the mounting bracket 51. In some embodiments, the drive motor 53 may also be mounted on the supporting connecting beam 2.

[0035] In this embodiment, by setting two transmission worm gears 52 and two lifting worm gears 55, with the two lifting worm gears 55 positioned on both sides of the support column 1, the stability of the supporting connecting beam 2 when driven and lifted by the drive assembly is improved. In this embodiment, a crossbeam is also provided at the top of the support column 1, with both ends of the crossbeam extending outward from the top of the support column 1, and the two transmission worm gears 52 connected to the two ends of the crossbeam.

[0036] In this embodiment, a fall prevention structure is also provided on the supporting connecting beam 2 or the sliding cage 4; The support column 1 is equipped with a groove or baffle that is compatible with the anti-fall structure. By setting the anti-fall structure, it is possible to prevent the support connecting beam 2 from falling accidentally after it has been raised and lowered into place.

[0037] In this embodiment, the supporting connecting beam 2 includes an upper beam portion 21 and two lower beam portions 22 that are fixedly connected; The supporting connecting beam 2 forms an H-shaped frame structure with the two supporting columns 1 through the upper beam part 21; There is a gap between the two lower beams 22; The upper workbench 31 is fixed to the upper beam 21; The two lower fixed platforms 33 are fixed to the lower beam 22; The bottoms of the two lower movable platforms 32 are movably connected to the two lower fixed platforms 33, and the tops of the two lower movable platforms 32 are movably connected to the bottom of the upper worktable 31. In this embodiment, by providing two lower beams 22 with a gap between them, interference and collision between the lower movable platforms 32 and the wing roots of the fuselage are avoided when the entire ground-rail type fuselage dock is in place.

[0038] In this embodiment, the bottom of the lower movable platform 32 is provided with pulleys 34, and the two lower movable platforms 32 are movably connected to the two lower fixed platforms 33 through the pulleys 34; The lower movable platform 32 includes an inclined section and a horizontal section. The horizontal sections of the two lower movable platforms 32 are close to each other. When the two lower movable platforms 32 are close to each other, the two lower movable platforms 32 are arched, thereby avoiding the wing root of the aircraft 6. This allows the height of the lower movable platform 32 to be reduced as much as possible, making it convenient for operators to operate from a position as close to the fuselage as possible.

[0039] In this embodiment, an elastic buffer pad is provided at one end of the two lower movable platforms 32 that are close to each other to prevent collisions when the two lower movable platforms 32 are close to each other.

[0040] In this embodiment, an auxiliary platform 12 is also provided on the support column 1 to facilitate operators to perform maintenance, painting and other operations on other parts of the machine body.

[0041] In this embodiment, at the bottom of the support column 1, a walking drive mechanism is also provided on both sides of the slide rail structure 11. The walking drive mechanism includes a walking motor and walking wheels. The walking motor drives the walking wheels to move the entire ground rail-type dock along the extension direction of the slide rail structure 11. The walking drive mechanism is a common existing technology and will not be described in detail here.

[0042] Example 2: This embodiment provides a docking station system, including two ground-rail type fuselage docks as described in Embodiment 1 above. The two ground-rail type fuselage docks are arranged symmetrically on both sides of the aircraft maintenance station.

[0043] In this embodiment, a guide rail 71 structure is also provided on the ground, and a slide rail structure 11 is provided on the guide rail 71 structure and slidably connected to it.

[0044] The remaining structures in this embodiment are the same as those in Embodiment 1 above, and will not be described again here.

[0045] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
