Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance equipment technology, and in particular to a small aircraft lifting device. Background Technology

[0002] In routine maintenance, repair, and parking scenarios, small aircraft often need to be raised to a certain height so that staff can easily operate on the bottom of the aircraft, such as the landing gear and components under the fuselage.

[0003] Chinese Patent 202321980550.5 relates to the field of small aircraft technology, and in particular to a small aircraft lifting device, including an operating platform. A triangular support plate is installed at the center of the top surface of the operating platform. Side slots are integrally formed on both sides of the lower part of the top surface of the operating platform, and movable support rods are respectively provided inside the side slots. A limiting plate is provided directly below the movable support rods. In this utility model, through the setting of inclined platform, rack, gear, triangular support plate, movable support rods, telescopic rods and drive motor, when the small aircraft is about to fly onto the operating platform, and a set of movable support rods that are stretched and flipped in the same direction are stretched to a suitable distance and contact the small aircraft, the device will use the guide space defined by the movable support rods to guide and assist the small aircraft about to fly onto the support plate, ensuring that it can accurately fly onto the support plate in one go, reducing the difficulty of piloting the small aircraft to accurately fly onto the support plate.

[0004] However, there are various models and specifications of small aircraft on the market. These small aircraft have different designs in many aspects, including the spacing between the two rear wheels. The spacing between the two rear wheels of many small aircraft is different. Some have a wider spacing, while others have a relatively narrower spacing, and the range of this difference is quite large.

[0005] However, the wheel limit seat on the rear side of the aforementioned lifting device is fixed. When facing small aircraft with different intervals between the rear wheels on both sides, it cannot accurately fit the rear wheels with different intervals, resulting in the inability to effectively limit the movement of these small aircraft, thus reducing its applicability. Therefore, a small aircraft lifting device is proposed to solve the above problems. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes a small aircraft lifting device. Through a moving mechanism, the distance between the wheel limit seats at both rear ends can be adjusted to ensure that the wheel limit seats at both rear ends fit with the rear wheels of the small aircraft, adapting to different spacing between the rear wheels of different small aircraft and improving versatility and applicability.

[0008] (II) Technical Solution

[0009] This utility model provides a small aircraft lifting device, including a base and a lifting plate. The upper surface of the base is provided with a lifting slot, and the inner bottom wall of the lifting slot is connected to the lifting plate through a lifting assembly for controlling the vertical lifting of the lifting plate.

[0010] It also includes wheel limit seats for limiting the wheels of small aircraft;

[0011] The upper surface of the lifting plate is provided with a second heightening plate, a first heightening plate, and a first inclined plate arranged horizontally in sequence. A movable slot is opened on the upper surface of the lifting plate between the first heightening plate and the first inclined plate. A partition block is installed in the middle of the movable slot. A movable mechanism of the partition block passes through the interior of the movable slot. The two movable ends of the movable mechanism are respectively connected to the movable plate. The upper ends of the second heightening plate and the two movable plates are respectively connected to the wheel limiting seat.

[0012] The right end face of the base is provided with a second inclined plate.

[0013] Preferably, all of the wheel limiting seats face to the left.

[0014] Preferably, the moving mechanism includes a drive motor, a threaded rod, and a moving block. The drive motor is located on the outer end face of the lifting plate. The threaded rod is rotatably connected between the inner walls of the moving slot and the middle of the partition block. The output shaft of the drive motor passes through the outer end face of the lifting plate and is coaxially connected to one end of the threaded rod.

[0015] Preferably, the threaded rod is a bidirectional threaded rod, and the threaded end of the threaded rod is symmetrical about the central axis of the spacer.

[0016] Preferably, it further includes a slider and a sliding plate, wherein the inner bottom wall of the movable slot and both sides of the partition are respectively connected to the sliding plate, one end of the slider is connected to the bottom of the movable block, and the other end of the slider is slidably connected to the sliding groove of the sliding plate.

When the threaded rod rotates, it causes the two moving blocks on both sides to move relative to each other inside the moving slot. When the moving blocks move, they can move the moving plate. The distance between the two moving plates can be controlled according to the usage requirements. When the moving plate moves, it can also move the wheel limit seats connected to it, thereby adjusting the distance between the wheel limit seats at both ends of the rear side. This ensures that the wheel limit seats at both ends of the rear side fit with the rear wheels of the small aircraft, adapting to different distances between the rear wheels of different small aircraft, improving versatility and applicability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1-5 As shown, the present invention proposes a small aircraft lifting device, including a base 6 and a lifting plate 1. The upper end surface of the base 6 is provided with a lifting slot 18. The inner bottom wall of the lifting slot 18 is connected to the lifting plate 1 through a lifting assembly, which is used to control the vertical lifting of the lifting plate 1.

[0032] It also includes wheel limit seats 4 for limiting the wheels of small aircraft;

[0033] The upper surface of the lifting plate 1 is provided with a second heightening plate 5, a first heightening plate 2 and a first inclined plate 7 arranged horizontally in sequence. A movable slot 12 is opened on the upper surface of the lifting plate 1 between the first heightening plate 2 and the first inclined plate 7. A partition block 3 is installed in the middle of the movable slot 12. A movable mechanism of the partition block 3 passes through the interior of the movable slot 12. The two movable ends of the movable mechanism are respectively connected to the movable plate 15. The upper ends of the second heightening plate 5 and the two movable plates 15 are respectively connected to the wheel limiting seats 4. The multiple wheel limiting seats 4 are all facing to the left.

[0034] The right end face of the base 6 is provided with a second inclined plate 8.

[0035] In this invention, when it is necessary to lift the aircraft, the lifting plate 1 is first lowered to the ideal lowest position by the lifting assembly. Then, according to the distance between the rear wheels of the small aircraft, the moving mechanism is adjusted, which drives the moving plates 15 on both sides to be adjusted so that they can drive the distance between the wheel limit seats 4 at both ends of the rear side to be adjusted. This ensures that the wheel limit seats 4 at both ends of the rear side are matched with the rear wheels of the small aircraft, adapting to different distances between the rear wheels of different small aircraft, and improving versatility and applicability.

[0036] Then, the small aircraft is driven onto the lifting plate 1 on the base 6 via the second tilting plate 8. At this time, the wheels of the small aircraft will be limited by the wheel limit seat 4. Then, the lifting component will drive the lifting plate 1 to rise and fall, which will facilitate the engineers to perform corresponding convenient inspections later.

[0037] In an optional embodiment, the moving mechanism includes a drive motor 10, a threaded rod 13, and a moving block 14. The drive motor 10 is located on the outer end face of the lifting plate 1. The threaded rod 13 is rotatably connected between the inner walls of the moving slot 12 and passes through the middle of the partition block 3. The output shaft of the drive motor 10 passes through the outer end face of the lifting plate 1 and is coaxially connected to one end of the threaded rod 13. The threaded rod 13 is a bidirectional threaded rod, and the threaded end of the threaded rod 13 is symmetrical about the central axis of the partition block 3. The second height-increasing plate 5 is connected to the middle of the left end face of the first height-increasing plate 2. The upper ends of the second height-increasing plate 5, the first height-increasing plate 2, the partition block 3, the first inclined plate 7, and the moving plate 15 are located on the same horizontal plane, ensuring that the bottom of the small aircraft is located on the same horizontal plane. The first inclined plate 7 facilitates the small aircraft to drive onto the second height-increasing plate 5 and the first height-increasing plate 2.

[0038] It should be noted that when the drive motor 10 is started, the drive motor 10 can drive the threaded rod 13 to rotate. When the threaded rod 13 rotates, it can drive the two moving blocks 14 to move relative to each other inside the moving slot 12. When the moving blocks 14 move, they can drive the moving plate 15 to move, so that the distance between the two moving plates 15 can be controlled according to the usage requirements. When the moving plate 15 moves, it can drive the wheel limit seat 4 connected to it to move accordingly.

[0039] In an optional embodiment, the slide block 19 and the slide plate 11 are also included. The inner bottom wall of the movable slot 12 and both sides of the partition block 3 are respectively connected to the slide plate 11. One end of the slide block 19 is connected to the bottom of the movable block 14, and the other end of the slide block 19 is slidably connected to the slide groove of the slide plate 11.

[0040] It should be noted that when the moving block 14 is moving, the slider 19 at the bottom of the moving block 14 can move within the groove of the slide plate 11, thereby ensuring the stability of the movement of the moving block 14.

[0041] In an optional embodiment, the lifting assembly includes a hydraulic rod 17 and a lifting rod 16, with multiple lifting rods 16 and hydraulic rods 17 disposed between the lifting plate 1 and the inner bottom wall of the lifting slot 18, and the hydraulic rod 17 located between multiple lifting rods 16.

[0042] It should be noted that the lifting plate 1 can be raised and lowered by the hydraulic rod 17. When the lifting plate 1 is raised and lowered, multiple lifting rods 16 will also raise and lower the lifting plate 1 accordingly, thereby ensuring the stability of the lifting plate 1.

[0043] In an optional embodiment, an anti-slip plate 9 is provided on the inclined surface of the second inclined plate 8.

[0044] It should be noted that the anti-slip plate 9 effectively prevents the small aircraft from slipping off the anti-slip plate 9 while moving along the second inclined plate 8, thus ensuring the safety and stability of the small aircraft during movement.

[0045] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
