[0040] See also Figure 1-4 As shown, an embodiment of the present invention provides an aircraft transport trailer, which includes a vehicle frame 1, a pair of lifting assemblies 4 and two pairs of skid pallets 5, wherein:

[0041] The vehicle frame 1 serves as the basic structure of the transport trailer. The vehicle frame 1 provides the necessary support and stability to carry the lifting assembly 4 and the skid pallet 5; a pair of lifting assemblies 4 are vertically and symmetrically connected to the rear of the vehicle frame 1, and are used to lift the skid pallet 5, and then the aircraft is supported and lifted by the two pairs of skid pallets 5 when needed, which is convenient for movement and loading; two pairs of skid pallets 5 are horizontally and symmetrically connected to both sides of the bottom end of the vehicle frame 1 near the middle, and are used to support and lift the aircraft so that the aircraft can be placed stably on the trailer for easy transportation.

[0042] During specific use, the aircraft is first guided to the vicinity of the trailer, and the skid pallet 5 is located under the aircraft, ready to support the aircraft; the lifting assembly 4 works to gradually lift the skid pallet 5 from the ground, and then under the action of the skid pallet 5, the wheels of the aircraft leave the ground, and the weight of the aircraft is transferred to the skid pallet 5; once the aircraft is lifted, the skid pallet 5 fixes the aircraft in an appropriate position to ensure that the aircraft does not move or slide during transportation; after the aircraft is fixed, the trailer can be towed or moved by itself to quickly transfer the aircraft from one location to another; after arriving at the destination, the lifting assembly 4 will be worked again to lower the aircraft so that its wheels touch the ground, and then the aircraft can be removed from the skid pallet 5.

[0043] The cooperation between the lifting assembly 4 and the skid plate 5 can realize the rapid transfer of aircraft, thereby improving the operational efficiency of the airport. The aircraft transport trailer is particularly suitable for a variety of aircraft, has good versatility, and has a simple structural design, which reduces the complexity of operation.

[0044] For further information, see Figure 1 、 2As shown, the aircraft transport trailer also includes a wheel set 3, which is arranged at the bottom of the vehicle frame 1. The wheel set 3 includes a front wheel 31, a pair of rear wheels 32 and a pair of auxiliary wheels 33. The front wheel 31 is arranged in the middle of the top of the vehicle frame 1, the pair of rear wheels 32 are symmetrically arranged at the tail end of the vehicle frame 1, and the pair of auxiliary wheels 33 are symmetrically arranged at the bottom of the vehicle frame 1, and the auxiliary wheels 33 are located between the front wheel 31 and the skid pallet 5.

[0045] Specifically in this embodiment, the wheel group 3 is a key part of the trailer movement. The wheel group 3 in this embodiment consists of a front wheel 31, a pair of rear wheels 32 and a pair of auxiliary wheels 33. The front wheel 31 is arranged in the middle of the top of the vehicle frame 1, and is responsible for the steering and direction control of the trailer; the pair of rear wheels are symmetrically arranged at the tail end of the vehicle frame 1, and are mainly responsible for supporting the weight of the trailer and providing propulsion; the pair of auxiliary wheels 33 are symmetrically arranged at the bottom of the vehicle frame 1, and are located between the front wheel 31 and the skid plate 5, for providing additional support and stability.

[0046] Thus, the configuration of the front wheels 31 and the rear wheels 32 gives the trailer good maneuverability and allows it to be flexibly moved within the airport; the addition of the auxiliary wheels 33 provides additional support, reduces the risk of the aircraft sliding or overturning during transportation, and further improves the stability of the trailer under different ground conditions, especially when loading heavy objects.

[0047] For further information, see Figure 1 As shown, the vehicle frame 1 includes a ladder frame 11, two side bars 12 and a fixed crossbeam 13. The two side bars 12 are horizontally and vertically connected to the two ends of the bottom edge of the ladder frame 11. The fixed crossbeam 13 is vertically connected between the two side bars 12 and is away from the side of the ladder frame 11. An auxiliary wheel 33 is installed at the bottom of the connection between the side bar 12 and the ladder frame 11. A front wheel 31 is installed at the bottom center of the top edge of the ladder frame 11, and a rear wheel 32 is installed at the bottom of the end of the side bar 12 away from the ladder frame 11.

[0048] In this embodiment, the ladder frame 11 serves as the main supporting structure of the vehicle frame 1, providing the basic shape and stability of the trailer; two side bars 12 are horizontally and vertically connected to the two ends of the bottom edge of the ladder frame 11, thereby enhancing the structural strength and load-bearing capacity of the vehicle frame; the fixed crossbeam 13 is used to further enhance the stability of the vehicle frame 1; the provision of the auxiliary wheels 33 improves the stability of the trailer on uneven ground and reduces the risk of damage to the trailer during transportation.

[0049] For further information, see Figure 1 As shown, the aircraft transport trailer also includes a towing rod 2, which is hingedly connected to the center of the top edge of the ladder frame 11. Preferably, the towing rod 2 includes a towing rod body 21 and a handle 22 vertically and symmetrically connected to the towing rod body 21, and the handle 22 is located on the side away from the ladder frame 11.

[0050] In this embodiment, the drawbar 2 is a component that connects the trailer and the towing equipment, allowing the trailer to be towed or pushed. The drawbar 2 in this embodiment is composed of a drawbar body 21 and a handle 22, wherein the handle 22 is used for the operator to hold and control the drawbar 2.

[0051] For further information, see Figure 1 、 2 As shown, the lifting assembly 4 includes a lifting mechanism 41, a lifting lever 42 and a fixed snap ring 43. The lifting mechanism 41 is vertically installed on the upper surface of the side bar 12 near the fixed beam 13, and the lifting lever 42 is vertically installed on the top of the lifting mechanism 41. Several fixed snap rings 43 are connected to the upper surface of the side bar 12, and the fixed snap rings 43 are suitable for fixing the extended arm of the lifting lever 42.

[0052] In this embodiment, the lifting mechanism 41 is responsible for realizing the lifting action and meeting the needs of different aircraft by controlling the lifting height; the lifting lever 42 serves as a transmission component, converting the movement of the lifting mechanism 41 into the movement of the lifting lever 42, thereby realizing the lifting or lowering of the aircraft; the design of the fixing clamp 43 ensures the stability and safety of the lifting lever 42 during operation.

[0053] For further information, see Figure 1 As shown, there are four skid supports 5 , which are evenly distributed on the lower surfaces of the two side bars 12 .

[0054] The skid pallet 5 is a key component for supporting and lifting the aircraft. Four skid pallets 5 are evenly distributed on the lower surfaces of the two side bars 12, providing a stable platform for supporting the aircraft and ensuring the balance and safety of the aircraft during transportation.

[0055] Furthermore, lifting mechanism 41 can be either a hydraulic cylinder or an electric winch. A hydraulic cylinder primarily achieves its lifting function through the pressure transmission of hydraulic oil. The hydraulic oil, pressurized by a vane pump, enters the cylinder through a series of control valves and pipelines, pushing the cylinder piston upward, thereby lifting the load. Hydraulic cylinders offer fast lifting speeds and high load capacity, making them suitable for scenarios requiring rapid and stable aircraft lifting.

[0056] Electric winches are powered by an electric motor, which transmits power to a lifting mechanism via a transmission device (such as gears and chains) to achieve the lifting of objects. The advantages of electric winches are ease of operation and control, making them suitable for applications requiring precise control of lifting speed and position.

[0057] Whether a hydraulic cylinder or an electric winch is used as the lifting mechanism 41, both can provide effective lifting functions for the aircraft transport trailer. The choice of which one to use depends on the specific operational requirements and environmental conditions. For example, a hydraulic cylinder is more suitable for heavy loads and fast operations, while an electric winch is more suitable for situations requiring fine control.

[0058] For further information, see Figure 1 As shown, the skid pallet 5 is a curved structure with an upward curvature. This upward curvature contributes to the stability and smoothness of the aircraft during placement and movement, reduces friction between the aircraft and the pallet, and provides a certain degree of elasticity to absorb vibrations that may occur during aircraft movement, protecting the aircraft structure from damage and improving operator comfort.

[0059] In addition, the curved skid plate 5 is easier to maintain and clean, thus reducing maintenance costs.

[0060] For further information, see Figure 1 、 2 As shown, the front wheels 31 and rear wheels 32 have the same structural dimensions, while the auxiliary wheels 33 have smaller dimensions than the front wheels 31 and rear wheels 32. This arrangement ensures that the front wheels 31 and rear wheels 32 have the same load-bearing capacity and rolling characteristics. This arrangement ensures consistent movement of the trailer in different directions, particularly during cornering and straight-line driving, providing stable support and balance.

[0061] In addition, the auxiliary wheels 33 are mainly used to provide additional flexibility and convenience in turning, and are usually used to provide additional support under certain conditions, such as providing auxiliary support on uneven ground or when loading and unloading an aircraft.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
