Abstract
Description
Technical Field
[0001] This utility model relates to the field of aviation material transportation tools, and in particular to a flatbed truck for transporting large aviation materials. Background Technology
[0002] A flatbed truck for transporting aviation materials is a specialized vehicle used within airports for transporting large aviation material packaging boxes. It typically features a flat, open carrying platform with a simple structure, high load-bearing capacity, and no obstructions such as cargo compartments, making it highly maneuverable. This allows aviation material packaging boxes to be placed directly on the platform for easy loading and unloading.
[0003] Currently, traditional flatbed trucks for transporting aircraft materials have many obvious drawbacks, as follows:
[0004] 1) The fixed frame length of the flatbed truck is not conducive to operation in airports where space is strictly controlled, and may sometimes affect airport operations and scheduling.
[0005] 2) The fixed size of the cargo area of the flatbed truck is not reasonable and is difficult to adapt to different specifications and sizes of aviation material packaging boxes, which limits the flexibility and versatility of transportation.
[0006] 3) The flatbed truck lacks limiters in its loading area. During transportation, the goods are prone to shifting due to bumps and shaking, which may not only cause damage to the goods but also pose safety hazards.
[0007] 4) During loading and unloading operations, traditional flatbed trucks require separate hoisting equipment, which undoubtedly increases equipment investment costs and complicates the operation process. Furthermore, the separation of conventional cranes from transport equipment results in high site occupancy rates and reduced transport efficiency. Utility Model Content

[0034] The frame 1 includes a front frame 11 and a rear frame 12. The top of the front frame 11 is provided with a slide groove 111. The rear frame 12 is slidably installed in the slide groove 111 of the front frame 11. The position between the front frame 11 and the rear frame 12 is adjusted by the length adjustment mechanism, so that the overall length of the frame 1 is adjustable.
[0035] The length adjustment mechanism includes a front threaded seat 71 fixedly disposed at the bottom of the front frame 11 along the front-rear direction, a rear threaded seat 72 fixedly disposed at the bottom of the rear frame 12 along the front-rear direction, and a screw 73 screwed into the front threaded seat 71 and the rear threaded seat 72. A handwheel 74 is fixedly disposed on the rear end of the screw 73, so that the position between the front frame 11 and the rear frame 12 can be adjusted by rotating the handwheel 74, thereby making the overall length of the frame adjustable.
[0036] The front frame 11 has gantry rails 112 on both sides of its top surface along the front-rear direction. The gantry rails 112 allow the gantry frame 2 to move back and forth on the front frame 11, which facilitates the hoisting of aviation material packaging boxes.

The second limiting rails 121 have spaced toothed limiting slots, and front and rear limiting plates 61 can be horizontally mounted in the toothed limiting slots. By locking the front and rear limiting plates 61 in the toothed limiting slots of the first limiting rail 113 and the second limiting rail 121 respectively, and adjusting the position of the front and rear limiting plates 61 in the toothed limiting slots according to the actual volume of the aviation material packaging box, aviation material packaging boxes of different volumes can be limited in the front and rear directions to avoid displacement and damage to the aviation materials during towing and movement.
[0041] Furthermore, the front and rear limiting plate 61 also has toothed limiting grooves, so that the left and right limiting plate 62 can be horizontally mounted in the toothed limiting grooves of the front and rear limiting plate 61, thereby limiting the packaging boxes of different volumes of aviation materials in the left and right directions, further avoiding displacement during towing and movement and causing damage to aviation materials.
[0042] Furthermore, a rear wheel is installed on the rear frame 12.
[0043] Preferably, in this embodiment, the motor 51 of the electric hoist 5 has a remote start / stop function, which facilitates the hoist 5 to lift aviation material packaging boxes.
[0044] The operating procedure for a large aircraft material transport flatbed truck in this case under actual working conditions is as follows:
[0045] 1. Adjust the length of the frame 1 using the length adjustment mechanism to adapt the flatbed to the requirements of the airport control area;
[0046] 2. The flatbed truck is towed to a position close to the aviation material packaging box, and the aviation material packaging box is hoisted onto the frame 1 by the shifting or rotating of the gantry 2, turntable 3, telescopic boom 4 and electric hoist 5.
[0047] 3. Front and rear limiting plates 61 are installed in the front and rear directions of the aircraft material packaging box, and left and right limiting plates 62 are installed in the left and right directions of the aircraft material packaging box, so that the aircraft material packaging box is limited in the front, rear, left and right directions on the flatbed truck, ensuring that it is not easy to shift during transportation and cause damage to the aircraft materials.
[0048] 4. Use a tractor unit to tow the flatbed truck to the unloading area to complete the transportation task.
[0049] Compared to existing technologies, the large aircraft material transport flatbed truck in this case can adjust the length of the frame through an adjustable mechanism to adapt the flatbed truck to airport control site requirements; the aircraft material packaging boxes can be hoisted onto the frame through the movement or rotation of the gantry, turntable, telescopic boom and electric hoist, resulting in high loading and unloading efficiency; front and rear limiting plates can be installed in the front and rear directions of the aircraft material packaging boxes, and left and right limiting plates can be installed in the left and right directions of the aircraft material packaging boxes, so that the aircraft material packaging boxes are limited in the front, rear, left and right directions on the flatbed truck, ensuring that they are not easily moved during transportation and thus preventing damage to the aircraft materials; the front and rear limiting plates and the left and right limiting plates are connected by slots, which is convenient, efficient and highly adaptable.
[0050] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
