Description

Technical Field

[0001] The present invention relates to the technical field of luggage transportation, and in particular to a pulley roller connection structure and a conveying device for airport luggage transportation. Background Art

[0002] In airport baggage handling systems, roller linkages are the core components that connect all conveying links, and their performance directly impacts the efficiency and stability of baggage transfer. Traditional roller linkages often utilize rigid, fixed structures, making the relative position and angle between adjacent rollers impossible to adjust, limiting the conveyor to linear motion along a fixed path.

[0003] However, airport baggage transportation scenarios are highly complex: different aircraft models have significant differences in cargo hold size, door height, and the direction of baggage loading and unloading channels; at the same time, the variety of baggage specifications, from small handbags to large suitcases, requires extremely high adaptability of the conveying structure. Traditional rigid connection structures are difficult to cope with these changes. When it is necessary to connect different aircraft or adjust the transportation route, the layout must be changed through manual disassembly and splicing of equipment. This is not only cumbersome and time-consuming, but also prone to baggage jamming, collisions, and even damage due to insufficient connection accuracy. In addition, the fixed spacing design makes the traditional structure unable to adapt to the transportation needs of baggage of different sizes, further restricting the overall efficiency of airport baggage transportation.

[0004] Therefore, a pulley roller connection structure and a conveying device for airport luggage transportation are proposed. Summary of the Invention

[0005] The object of the present invention is to provide a pulley roller connection structure and a conveying device for airport luggage transportation, aiming to solve or improve at least one of the above-mentioned technical problems.

[0006] To achieve the above-mentioned object, the present invention provides the following solution: The present invention provides a pulley roller connection structure for airport luggage transportation, comprising a pulley connection assembly, wherein the pulley connection assembly is arranged between two adjacent conveyor rollers, support frames are installed on both sides of the conveyor rollers, a crossbar is installed between the two support frames, and a roller is installed at the bottom of the support frame;

[0007] The pulley connection assembly includes a first connecting frame, a second connecting frame and a rotating shaft, wherein the first connecting frame is fixedly mounted on the crossbar, the rotating shaft is rotatably connected to the crossbar, and a rotating shaft deflection limiting component is mounted on the crossbar;

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-Figure 5 The present invention provides a pulley roller connection structure for airport luggage transportation, including a pulley connection assembly, the pulley connection assembly is arranged between two adjacent conveyor rollers 2, support frames 3 are installed on both sides of the conveyor rollers 2, a crossbar 5 is installed between the two support frames 3, and a roller 4 is installed at the bottom of the support frames 3;

[0029] The pulley connection assembly includes a first connecting frame 6, a second connecting frame 7 and a rotating shaft 1. The first connecting frame 6 is fixedly mounted on the crossbar 5. The rotating shaft 1 is rotatably connected to the crossbar 5. A rotating shaft deflection limiting component is mounted on the crossbar 5.

[0030] Two first pulley assemblies arranged side by side are installed on the rotating shaft 1, first slide grooves 8 are respectively opened on both sides of the second connecting frame 7, and a second slide groove 9 is opened at the center of the second connecting frame 7. The two first pulley assemblies are respectively slidably connected to the two first slide grooves 8. The second pulley assembly is installed on the first connecting frame 6, and the second pulley assembly is slidably connected to the second slide groove 9;

[0031] With such an arrangement, the pulley connection assembly of the present invention is composed of a first connecting frame 6, a second connecting frame 7 and a rotating shaft 1. The first pulley assembly on the rotating shaft 1 is slidably connected to the first slide grooves 8 on both sides of the second connecting frame 7, and the second pulley assembly on the first connecting frame 6 is slidably connected to the second slide groove 9 in the center of the second connecting frame 7. This realizes the flexible adjustment of the distance between adjacent conveyor rollers 2, can quickly adapt to the layout of the cargo hold of different models of aircraft, the height of the cabin door and various specifications of luggage, and can complete the adjustment without disassembling the equipment, which greatly improves the adaptability of the equipment to complex scenarios.

[0032] When the present invention is in the longest state, the first pulley assembly abuts against the end of the first chute 8, and the second pulley assembly abuts against the end of the second chute 9, thereby achieving automatic locking in the length direction and improving the conveying stability.

[0033] When the first pulley assembly of the present invention slides in the first chute 8 and the second pulley assembly slides in the second chute 9, the motion trajectory is stable, and the angle and spacing between adjacent conveyor rollers 2 change smoothly in conjunction with the rotation of the rotating shaft 1. The rotating shaft deflection limiter can limit excessive deflection and counterclockwise deflection of the rotating shaft 1, avoiding unstable luggage conveying due to excessive angle adjustment, ensuring that the luggage will not get stuck, collide or fall during the conveyance process, and significantly improving the safety and stability of luggage transportation.

[0034] The sliding fit between the pulley assembly and the slide groove of the present invention reduces rigid friction and lowers the wear rate of components; the rotational connection between the rotating shaft and the cross bar and the reasonable force distribution of each component can effectively buffer the impact and vibration generated during luggage transportation and extend the service life of the equipment; with the flexible adjustment function of the pulley connection assembly, the equipment can quickly adapt to different transportation scenarios, reducing the time for equipment disassembly and reassembly due to scene switching; the stable transportation performance reduces the probability of luggage damage and improves overall transportation efficiency.

[0035] To further optimize the solution, the first pulley assembly includes a first connecting rod 10 and a first pulley body 11. One end of the first connecting rod 10 is rotatably connected to the first pulley body 11, and the other end is fixed to the outer wall of the rotating shaft 1. The two first pulley bodies 11 are respectively slidably connected to the two first sliding grooves 8.

[0036] According to a further optimized solution, the second pulley assembly includes a second connecting rod 12 and a second pulley body 13 , one end of the second connecting rod 12 is rotatably connected to the second pulley body 13 , and the other end is fixedly connected to the first connecting frame 6 .

[0037] A further optimized solution is that the shaft deflection limit component includes two limit blocks 14 set at intervals, both limit blocks 14 are fixedly mounted on the cross bar 5, and a protrusion 15 is installed at one end of the shaft 1, and the protrusion 15 is located between the two limit blocks 14 to limit the rotation angle of the shaft 1.

[0038] Further optimization scheme, the second connecting frame 7 includes a transverse bracket, an end wing plate and a center wing plate. There are two end wing plates, which are respectively fixedly mounted on both sides of the transverse bracket, and the center wing plate is fixedly mounted at the center of the transverse bracket. A first slide groove 8 is provided on the end wing plate, and a second slide groove 9 is provided on the center wing plate.

[0039] In a further optimized solution, a reinforcing rib 16 is installed between the transverse bracket and the end wing plate.

[0040] As a further optimization, the conveyor roller 2 is coated with an elastic rubber layer and features a curved transition section at its edge. The rubber layer absorbs the impact of luggage being placed, while the curved transition section prevents scratches on the luggage's edges, making it particularly suitable for handling fragile luggage and enhancing safety during transportation.

[0041] To further optimize the solution, dustproof seals and protective covers are installed at the first and second chutes 8, 9, and at the connection between the shaft 1 and the crossbar 5. The seals prevent dust and debris from entering the chutes and affecting the sliding of the pulleys, while the protective covers protect the shaft and other components from external contamination and collisions. This is particularly suitable for dusty environments such as open-air transfer areas at airports.

[0042] The present invention also provides a pulley roller conveyor device for airport luggage transportation, comprising a pulley roller connection structure for airport luggage transportation, and further comprising a plurality of conveying rollers 2, at least one of which is a powered roller;

[0043] The power roller serves as the primary power source, rotating via a built-in servo, thereby driving the luggage along the conveying direction. The remaining conveyor rollers (two rollers) passively rotate due to the friction of the luggage, assisting in conveying. While the power rollers provide the primary driving force, their heavy weight and relatively complex structure result in a slightly higher failure rate than standard conveyor rollers. However, the device's "single power roller + multiple passive rollers" combination ensures conveying power while reducing the number of power components and overall risk of failure. When the power rollers are operating, their rotation is transmitted to the other conveyor rollers through friction between the luggage and the rollers, forming a continuous transport power chain that ensures stable luggage movement regardless of the device's configuration.

[0044] As a further optimization, vision sensors and RFID readers are installed at the conveyor entrance. These, combined with a control system, identify baggage size, weight, and destination. When a baggage requiring diversion is detected, the speed or angle of the conveyor rollers in the corresponding area is adjusted, coupled with precise control of the shaft deflection limiter, to automatically divert the baggage, improving transportation efficiency.
