[0002] In modern air transportation, the efficiency and safety of the baggage handling system are the keys to ensuring passenger satisfaction and smooth airport operation. As an important link in the baggage handling process, the rationality of the design of the baggage conveyor belt directly affects the safe transmission and handling efficiency of the baggage.

[0003] In the existing baggage conveyor belt system, especially in some parts with an inclined design, although it can realize the natural sliding of the baggage from a high place to a low place, when the discharge end of the conveyor belt is connected to the ground or other receiving equipment, the effective buffering of the impact of the falling baggage is often ignored. Due to the lack of necessary buffer protection measures, the baggage directly impacts the ground or the surface of the receiving equipment during the falling process, which not only easily causes damage to the baggage, but also generates noise, affecting the airport operation environment. This not only leads to unnecessary economic losses, but also reduces the passenger satisfaction with the airport service, and at the same time affects the overall practicability and reliability of the conveyor belt system. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a civil aviation ground auxiliary docking device integrated with a transfer case, so as to solve the problems existing in the current inclined baggage conveyor belt system in the above background art, mainly including insufficient buffer protection at the discharge end, resulting in the direct impact of the falling baggage on the ground or the receiving equipment, causing baggage damage, generating noise, and then leading to economic losses, decreased passenger satisfaction, and impaired practicability and reliability of the system.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A civil aviation ground auxiliary docking device integrated with a transfer case, including a frame. Four rollers driven by a single integrated transfer case are arranged at the bottom of the frame. Support plates are arranged on both sides of the top of the frame. A top frame is arranged at the top of the support plates. A conveyor belt with an adjustable inclination angle driven by a hydraulic telescopic rod is arranged at the top of the top frame. An activity plate is arranged at the lower end of the conveyor belt of the top frame. A plurality of platform plates distributed in a stepped manner are arranged on the outer side of the activity plate. Buffer rollers are rotatably connected to the outer ends of the platform plates. And a regulation mechanism for adjusting the inclination angle of the activity plate is arranged on the outer side of the front end of the support plate.

[0006] Preferably, the regulation mechanism on the outer side of the front end of the support plate includes a cylinder, a push bar plate and a linkage shaft.

[0007] Preferably, the platform plates are distributed outwardly inclined on the outside of the movable plates, and notches are formed at the outer ends of the platform plates, and both ends of the buffer rollers are connected to the inner walls on both sides of the notches at the outer ends of the platform plates through rotating shafts.

[0008] Preferably, a plurality of buffer strips are arranged around the outer wall of the buffer roller, and the inner wall of the buffer strip is connected to the outer wall of the buffer roller through an elastic pad.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a civil aviation ground auxiliary docking device with an integrated transfer case, including a vehicle frame 1. Four rollers driven by an integrated transfer case are arranged at the bottom of the vehicle frame 1. The transfer case is fixedly installed in the middle of the top of the vehicle frame 1 and serves as an efficient power distribution device. It can reasonably and dynamically distribute a single power source (usually the power generated by an electric motor or a hydraulic motor) to each roller, ensuring that each roller can obtain appropriate driving force and rotational speed under different ground conditions and steering requirements, so as to realize the flexible movement of the entire device. Support plates 2 are arranged on both sides of the top of the vehicle frame 1. A top frame 3 is arranged at the top of the support plate 2. A conveyor belt 4 with an adjustable tilt angle driven by a hydraulic telescopic rod is arranged at the top of the top frame 3. And a movable plate 5 is arranged at the lower end of the conveyor belt 4 on the top frame 3. A number of platform plates 6 distributed in a stepped manner are arranged on the outer side of the movable plate 5. Buffer rollers 7 are rotatably connected to the outer ends of the platform plates 6. And a regulating mechanism for adjusting the tilt angle of the movable plate 5 is arranged on the outer side of the front end of the support plate 2. The tilt angle of the movable plate 5 of this structure can be adjusted by the regulating mechanism to ensure a smooth transition with the conveyor belt 4. And the surfaces of the stepped platform plates 6 arranged on the outer side of the movable plate 5 are covered with high-friction materials (such as silicone, rubber, etc.) to form a progressive deceleration area. When the luggage slides down through the conveyor belt 4, it will gradually decelerate on these platform plates 6 until it is smoothly placed on the ground or other receiving equipment, greatly reducing the impact force of direct fall. At the same time, buffer rollers 7 are assembled at the outer ends of each layer of platform plates 6 to further absorb the impact energy and reduce the collision sound, creating a quiet airport environment. Thus, the device can significantly enhance the protection measures during the luggage falling process, effectively avoid luggage damage, reduce noise pollution, improve the satisfaction of passengers with airport services, and at the same time enhance the practicability and reliability of the conveyor belt system, achieving a double improvement in safety and efficiency during the luggage handling process. The regulating mechanism on the outer side of the front end of the support plate 2 includes a cylinder 9, a push bar plate 10 and a linkage shaft 11. The cylinder 9 is fixed to the top of the outer side of the front end of the support plate 2 by bolts, and the output end of the cylinder 9 faces downward. The push bar plate 10 is fixed to the output end of the cylinder 9 and is slidably connected to the support plate 2. The linkage shafts 11 are symmetrically connected between the two ends of the push bar plate 10 and the inner side of the bottom end of the movable plate 5. And the connections between the linkage shafts 11 and the push bar plate 10 are all in a way of being rotatably connected by pin shafts. When the cylinder 9 of this structure works, it pushes the push bar plate 10 downward or upward. The sliding of the push bar plate 10 is then transmitted to the linkage shafts 11 through the pin shafts. The linkage shafts 11 drive the bottom end of the movable plate 5 to produce linkage, enabling it to accurately change the tilt angle. This linkage mechanism realizes the real-time regulation of the tilt angle of the movable plate 5, ensuring that during the sliding process of the luggage on the conveyor belt 4, it can gradually buffer and decelerate along the stepped platform plates 6 and finally land smoothly, greatly reducing the impact force and noise. The platform plates 6 are all distributed outwardly inclined on the outer side of the movable plate 5. The connection between the inner end of the platform plate 6 and the movable plate 5 is fixed by welding, and a notch is opened at the outer end of the platform plate 6.In addition, both ends of the buffer roller 7 are connected to the inner walls of both sides of the notch at the outer end of the platform plate 6 through a rotating shaft. The platform plate 6 of this structure constructs a stable transition area on the outer side of the movable plate 5 that is conducive to the slow descent of the luggage. This outward inclined structural layout ensures that when the luggage slides from the conveyor belt 4 to the platform plate 6, it can naturally decelerate along the inclined step surface, dispersing the falling kinetic energy, and the buffer roller 7 can rotate appropriately when under pressure to further buffer the force of the luggage falling. Four buffer strips 8 are arranged around the outer wall of the buffer roller 7, and the inner wall of the buffer strip 8 is connected to the outer wall of the buffer roller 7 by an elastic pad. The buffer strip 8 of this structure serves as the first contact surface that directly contacts the luggage. Through its own elastic material (such as rubber or polyurethane), it absorbs and disperses the impact force at the moment of luggage touching, effectively reducing the direct impact force when the luggage falls, and the elastic pad (such as sponge material) between the buffer strip 8 and the buffer roller 7 can further enhance the flexibility and resilience of the buffer structure. When the luggage presses the buffer strip 8, the elastic pad is pressed The movable plate 5 shrinks and then slowly returns to its original state. This dynamic buffer mechanism not only absorbs more impact energy, but also reduces the rebound phenomenon caused by direct hard collision, making the transition of luggage softer. A fixed shaft 12 is provided on the outer side of the movable plate 5. The connection points between the two ends of the fixed shaft 12 and the movable plate 5 are both welded and fixed. The outer rotation of the fixed shaft 12 is connected with a rotating sleeve 13, and the outer side of the rotating sleeve 13 is symmetrically provided with a pressure column 14. The outer end of the pressure column 14 is welded and fixed with a support block 15. The rotating sleeve 13 is symmetrically provided with a pressure hole that matches the inner end structure of the pressure column 14, and the outer sleeve of the pressure column 14 is provided with a compression spring 16. In this structure, when the movable plate 5 adjusts the tilt angle, the rotating sleeve 13 rotates to a suitable angle outside the fixed shaft 12. At this time, the pressure column 14 can extend through the pressure hole and make the support block 15 firmly against the inner side of the movable plate 5 with the assistance of the compression spring 16, so as to provide a stable support for the movable plate 5, ensure stability and safety during operation, and realize effective fixation and buffer support of the movable plate 5 at different tilt angles.

[0019] Working principle: When using the civil aviation ground auxiliary docking device with integrated transfer case, first, when the device is started, the single power source generated by the electric motor or hydraulic motor is dynamically distributed to the four bottom rollers through the transfer case integrated in the center of the top of the frame 1, driving the entire device to move flexibly to the working position, and then starting the cylinder 9 to push the push plate 10 downward or upward, and the sliding distribution shaft of the push plate 10 is transmitted to the linkage shaft 11, and the linkage shaft 11 then drives the movable plate 5 to adjust to the inclination angle matching the conveyor belt 4, and the luggage on the conveyor belt 4 slides down, first contacts the buffer strip 8 on the buffer roller 7, and buffers the initial impact through the elastic pad, and then gradually decelerates along the stepped platform plate 6 on the outside of the movable plate 5. The high friction material of each layer of the platform plate 6 and the outer end buffer roller 7 further absorb energy to ensure that the luggage is smoothly transferred to the ground or other receiving equipment. In this process, the rotating sleeve 13 rotates outside the fixed shaft 12 in time, the pressure column 14 extends through the pressure hole, and the support block 15 firmly supports the movable plate 5 under the action of the compression spring 16, ensuring the stability and safety of the entire operation, thereby completing a series of work.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
