Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a foldable connector for airport cargo. Background Technology

[0002] With economic development and improved living standards, air travel has become an increasingly popular choice for many. According to relevant civil aviation regulations, most passenger baggage needs to be checked in. The baggage handling system is one of the core systems of an airport, and its safe and efficient operation directly affects the normal operation of the airport and the overall flight schedule. Baggage handling systems are characterized by their large footprint, system complexity, and wide-ranging impact from equipment failures. Connectors are a crucial component of the baggage handling system; baggage slides on conveyor rollers, enabling rapid transfer of baggage.

[0003] The existing connectors have the following problems when in use:

[0004] 1. When the heights of the baggage receiving side and the baggage conveying side are different, the height of the top support plate of the connector is usually the same as that of the baggage receiving side. Therefore, the baggage needs to be lifted by staff and placed on the top support plate for conveying, which is physically demanding.

[0005] 2. The connector is usually fixed by bolts or welding. The height of the top support plate is relatively fixed. When adjusting, the bolts need to be removed, which is inconvenient. Although the height of the top support plate can be adjusted, the position and height of the bracket are fixed, which occupies a lot of space.

[0006] To address the aforementioned technical problems, this application proposes a foldable connector for airport cargo transport. Utility Model Content

[0007] I. Technical problems to be solved

[0008] The technical problem this invention aims to solve is that while the height of the top support plate can be adjusted, the position and height of the bracket are fixed, occupying a large amount of space; luggage needs to be lifted by staff and transported to the top of the top support plate, a process that consumes a lot of physical strength.

[0009] II. Technical Solution

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] As attached Figure 2As shown, a foldable docking device for airport cargo includes a base frame 1. Multiple sets of wheels 2 are installed at the bottom of the base frame 1, facilitating the docking device's movement. A horizontally placed U-shaped frame 3 is installed on each opposite side of the base frame 1. Hydraulic telescopic rods 4 pass through the side walls of each U-shaped frame 3, with their extended ends facing downwards and fitted with support blocks 5. Power supply equipment is installed at the bottom of the base frame 1. The multiple sets of hydraulic telescopic rods 4 share the same control switch, allowing them to operate simultaneously with identical extension and retraction lengths. The extension of the hydraulic telescopic rods 4 supports the support blocks 5 on the ground, lifting the wheels 2 off the ground and positioning the docking device.

[0030] As attached Figure 2 As shown, a lifting frame 7 is provided above the base frame 1. The upper and lower side walls of the lifting frame 7 are U-shaped grooves. A scissor lift 6 is connected between the top of the lower U-shaped groove of the lifting frame 7 and the base frame 1. The scissor lift 6 drives the lifting frame 7 to move up and down, so that the upper height of the lifting frame 7 is close to the luggage receiving height. Multiple sets of rollers 8 are rotatably installed at the bottom of the upper U-shaped groove of the lifting frame 7. The luggage is supported on the upper side of the multiple sets of rollers 8. By gently pushing the luggage, the luggage moves inside the upper U-shaped groove of the lifting frame 7 for luggage transportation.

[0031] To conserve the energy of staff, as shown in the attached document... Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a loading rack 10 is rotatably mounted on one side of the lifting frame 7. Connecting shafts 9 are respectively installed on the upper edges of the opposite side walls of the lifting frame 7. A connecting sleeve 14 is installed on the upper edge of one side wall of the loading rack 10. The connecting sleeve 14 is rotatably sleeved on the outside of the connecting shaft 9, so that the loading rack 10 is rotatably connected to the lifting frame 7. After the height of the lifting frame 7 is determined, the loading rack 10 is rotated from the side of the lifting frame 7 until it contacts the ground or luggage stacking platform. The upper and lower sides of the loading rack 10 are both mounting groove structures. A conveyor belt 1 is provided on the inner upper part of the loading rack 10. 1. Multiple sets of anti-slip crossbars 13 are provided on the outer side of the conveyor belt 11. A conveying device 12 that drives the conveyor belt 11 to rotate is installed on the inner side of the upper part of the loading rack 10. The conveying device 12 includes multiple sets of conveying rollers and a drive motor. The drive motor drives a set of conveying rollers to rotate, which in turn drives the conveyor belt 11 to rotate. The other multiple sets of conveying rollers support the conveyor belt 11. The axis of the conveying rollers is parallel to the axis of the roller 8. The staff pulls the luggage to the upper side of the lower part of the conveyor belt 11, and the luggage is transported upward to the upper side of the lifting frame 7 through the conveyor belt 11, saving the staff's physical strength.

[0032] When the connector is not in use, the lifting frame 7 is retracted downwards by the scissor lift 6, and the loading rack 10 is rotated upwards to the upper side of the lifting frame 7 and supported on the upper side of multiple sets of rollers 8. A hanging rod 20 is installed on the side of the front wall of the lifting frame 7 away from the loading rack 10. A locking hook 21 is rotatably connected to the side of the front wall of the loading rack 10 away from the lifting frame 7. Rotating the locking hook 21 will put the locking hook 21 on the outside of the hanging rod 20. The structure of the locking hook 21 is the same as the principle of the key buckle structure. The limiting plate rotatably connected to the opening side of the locking hook 21 prevents the locking hook 21 from detaching from the outside of the hanging rod 20.

[0033] Example 2

[0034] When there is no suitable support under the loading rack 10, such as... Figure 2 and attached Figure 4 As shown, an angle adjustment and positioning assembly is installed between the lower side of the loading rack 10 and the lower side of the lifting frame 7. The angle adjustment and positioning assembly includes two sets of positioning frames 15 and two sets of connecting plates 17. The two sets of positioning frames 15 are respectively installed on the lower sides of the front and rear side walls of the loading rack 10, and the two sets of connecting plates 17 are respectively installed on the lower sides of the front and rear side walls of the lifting frame 7. The positioning frame 15 is located inside the connecting plate 17 and is in contact with the inner wall of the connecting plate 17 on the same side. The positioning frame 15 has a first positioning through hole 16, and the connecting plate 17 has multiple sets of second positioning through holes 18 equidistantly arranged. A connecting bolt 19 passes through the first positioning through hole 16 and the corresponding second positioning through hole 18. A nut is fitted on the outer side of the tail end of the connecting bolt 19. By rotating the loading rack 10, the positioning through hole 16 can be aligned with the positioning through hole 18 at different positions. By passing the connecting bolt 19 through the positioning through hole 16 and the corresponding positioning through hole 18, the loading rack 10 is positioned at different angles. The nut is tightened on the outside of the connecting bolt 19 to fix the position of the loading rack 10. The height of the lower side of the loading rack 10 can be adjusted in the above way. By the gravity of the lifting frame 7, the bottom frame 1 and the scissor lift 6 and the supporting force of the support block 5, the lower side of the loading rack 10 can be brought close to the height of the luggage stacking, and the lower side of the loading rack 10 does not need to be supported, so that the luggage can be transported.
