Description

Technical Field

[0001] This utility model relates to the technical field of transfer trailer devices, specifically a hydraulic lifting aircraft trailer. Background Technology

[0002] Skid-type landing gear is a common type of landing gear used on small aircraft and drones. Because it lacks wheels for movement, the aircraft relies on other equipment (such as aircraft transfer carts) for short-distance movement from the hangar to the apron outside, and for other short-distance movements. Current aircraft transfer carts typically use simple wheels with levers to move the aircraft, but these devices have significant drawbacks: they provide insufficient lift and are prone to friction with the ground; they are only suitable for very small aircraft, limiting their application; they are less suitable for larger aircraft; and their operation requires multiple operators, making them unsuitable for meeting the demands of aircraft movement.

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figure 1 and Figure 2 The present invention relates to a hydraulic lifting aircraft trailer, comprising a chassis 1 and a hydraulic lifting module.

[0025] The vehicle body chassis 1 is a rectangular frame, and the vehicle body chassis 1 is provided with multiple rollers 11; in this embodiment, there are four rollers 11, which are arranged in two groups on both sides of the vehicle body chassis 1, and the rollers 11 enable the vehicle body chassis 1 to move easily.

[0026] The hydraulic lifting module comprises two lifting components and a lifting bracket 6. The two lifting components are located on opposite sides of the vehicle chassis 1, and the lifting bracket 6 is located between the two lifting components. Specifically, each lifting component includes a hydraulic cylinder 5, an active rotating support rod 3, and a driven rotating support rod 4. The lower ends of the hydraulic cylinder 5, the active rotating support rod 3, and the driven rotating support rod 4 are rotatably connected to the vehicle chassis 1. The upper end of the telescopic shaft of the hydraulic cylinder 5 is rotatably connected to the middle of the active rotating support rod 3. The side of the lifting bracket 6 is rotatably connected to all the active rotating support rods 3 and all the driven rotating support rods 4, and the lifting bracket 6 is parallel to the vehicle chassis 1. When the telescopic shaft of the hydraulic cylinder 5 extends, the angle between the active rotating support rod 3 and the lifting bracket 6 increases (the angle varies within the range of 0-90°). At this time, the vertical distance between the lifting bracket 6 and the vehicle chassis 1 increases, and the height of the lifting bracket 6 rises.

[0027] When the aircraft trailer is in operation, it is first moved to the underside of the aircraft 8 to be moved via the rollers 11. The hydraulic cylinder 5 is activated to control the extension shaft of the hydraulic cylinder 5 to extend and raise the height of the lifting bracket 6, so that the lifting bracket 6 lifts the aircraft 8 upward and the landing gear of the aircraft 8 leaves the ground. Then, the aircraft 8 is moved to the designated position by using a power unit (trailer) or by manually pulling the aircraft trailer.

[0028] In a preferred embodiment, the lifting bracket 6 is a rectangular frame structure. The lifting bracket 6 includes two longitudinal rods and multiple transverse rods. The longitudinal rods are rotatably connected to the active rotating support rod 3 and the driven rotating support rod 4. The two ends of the transverse rods are fixedly connected to the longitudinal rods.

[0029] In a preferred embodiment, all four wheels 11 are omnidirectional wheels. The omnidirectional wheels allow the chassis 1 to move easily, facilitating its access to the underside of the aircraft 8.

[0030] In a preferred embodiment, a tow bar 2 is provided at one end of the vehicle chassis 1, and a tow ring 21 is provided at one end of the tow bar 2. The tow ring 21 is used to facilitate the connection of a tow rope for towing the trailer and aircraft 8.

[0031] In a preferred embodiment, the vehicle chassis is provided with a plurality of hinge seats 12, and the lower ends of the hydraulic cylinder 5, the active rotating support rod 3 and the driven rotating support rod 4 are all hinged to the hinge seats 12, so that the lower ends of the hydraulic cylinder 5, the active rotating support rod 3 and the driven rotating support rod 4 are rotatably connected to the vehicle chassis 1.

[0032] In a preferred embodiment, a support plate 7 is provided on each side of the vehicle chassis. The hydraulic lifting aircraft trailer also includes multiple telescopic sleeves 13. Specifically, there are four telescopic sleeves 13, arranged in two groups on each side of the vehicle chassis 1 (two on each side). All four telescopic sleeves 13 are fixed to the bottom of the vehicle chassis 1. Multiple telescopic rods 71 ​​are provided on the two support plates 7 (two telescopic rods 71 ​​on each support plate). The telescopic rods 71 ​​are perpendicular to the support plates 7 and are slidably disposed within the telescopic sleeves 13. The cooperative structure of the telescopic rods 71 ​​and the telescopic sleeves 13 allows for convenient adjustment of the distance between the two support plates 7. Each support plate 7 has a support groove on its side. The aircraft 8 to be moved has two landing gear base rods 81 at the bottom of its landing gear. The landing gear base rods 81 are supported in the support grooves. This allows the aircraft to be supported on the aircraft trailer by the landing gear, avoiding the aircraft having to bear its own weight on the bottom of the fuselage. In this embodiment, when the hydraulic lifting aircraft trolley is in use, after the aircraft is lifted upward by the lifting bracket 6, the landing gear base rod 81 is aligned with the support groove on the side of the support plate 7. Then, the two support plates 7 are moved outward so that the two landing gear base rods 81 of the aircraft are respectively located in the two support grooves. Then, the hydraulic cylinder 5 drives the lifting bracket 6 to slightly lower the height so that the landing gear base rods 81 are supported in the two support grooves, thereby the aircraft is supported on the aircraft trolley by the landing gear.
