Description

Technical Field

[0001] This utility model belongs to the field of civil aviation bulk baggage transportation, and specifically relates to a civil aviation bulk baggage trailer with waterproof function. Background Technology

[0002] Currently, baggage handling on the tarmac commonly uses loose cargo trailers to transport checked baggage. The operational guidelines for loading and unloading stipulate that baggage unloaded in rainy or snowy weather must be lined with plastic sheets to prevent it from getting wet and causing passenger complaints. However, in daily operations, lining baggage carts with plastic sheets during rainy or snowy weather often results in water accumulation due to the lack of drainage, leading to wet baggage, passenger complaints about baggage satisfaction, and impacting service quality.

[0003] If plastic sheeting is not recycled in time, or if it is blown away by the wind during strong winds, it may cause serious FOD safety risks on the apron. If the use of mats is promoted, there is no need to use plastic sheeting, thus solving this FOD risk at the source.

[0004] After prolonged use, the paint on the carriage floor may peel off due to rain erosion and high-temperature exposure, and the internal iron plates may rust, which can easily scratch and stain passengers' luggage.

[0005] Based on this, this utility model proposes a civil aviation bulk cargo trailer with waterproof function. Utility Model Content

[0006] To address the aforementioned problems in the prior art, this utility model provides a civil aviation bulk cargo trailer with waterproof function, including a cargo box body and wheels. The bottom of the cargo box body is provided with a plurality of mutually detachable and fixedly connected grid pad assemblies, on which bulk cargo is placed.

[0007] At least one drainage hole is provided at the bottom of the carriage body.

[0008] Furthermore, each of the aforementioned grid pad assemblies includes a grid unit and a support assembly;

[0009] Two adjacent grid units are detachably and fixedly connected, and a grid unit is fixed on the upper surface of the support assembly.

[0010] Furthermore, the support components are arranged circumferentially along the outer edge of the grille unit, and the circumferentially arranged support components are arranged in an array that is proportionally reduced from the edge of the grille unit to the center at a set interval.

[0011] Furthermore, the grille unit includes a frame and grille bars;

[0012] The frame is fixed to the outermost support component, and the inner surface of the frame is fixed to multiple grid strips, which are arranged parallel and at an angle.

[0013] Furthermore, the support component has multiple slots spaced at predetermined intervals.

[0014] Furthermore, the carriage body has a cavity for accommodating loose cargo luggage, and the carriage body has a top opening communicating with the cavity, through which loose cargo luggage can be taken out and put in the cavity. The carriage body is provided with a waterproof cloth, which is used to cover the top opening.

[0015] Furthermore, the two side panels along the length of the carriage body are provided with side openings that communicate with the cavity and the top opening. Both sides of the carriage body are provided with opening and closing doors corresponding to the side openings. The opening and closing doors can switch between open and closed states. When the opening and closing doors are in the open state, loose cargo luggage can be taken out and put into the cavity through the side openings. When the opening and closing doors are in the closed state, the loose cargo luggage in the cavity is contained.

[0016] Furthermore, guide rails matching the cross-sectional shape are installed on both sides of the top opening, and the waterproof cloth passes through the guide rails and moves along the guide rails.

[0017] Furthermore, the grille pad assembly that contacts the opening and closing door is fixed to the vehicle body via a detachable connecting assembly.

[0018] Furthermore, the spacing between two adjacent grille bars is smaller than the width of the luggage wheel.

[0019] The beneficial effects of this utility model are:

[0020] The drainage holes at the bottom of the carriage, combined with the grille pad structure, can quickly drain rainwater accumulated during rain and snow, preventing luggage from being damaged by water and significantly reducing the risk of complaints about wet luggage.

[0021] The grating pad replaces the traditional plastic sheet, avoiding the risk of plastic sheet not being recycled in time or being blown away by strong winds, and completely eliminating the safety hazards of FOD (Foreign Object Debris) on the apron caused by this.

[0022] The grille pad covers the car floor, isolating luggage from direct contact with the metal floor, preventing rust or peeling paint from scratching or soiling the luggage, while also reducing the impact of rain and sun exposure on the floor, thus extending the service life of the car.

[0023] Eliminating the cumbersome process of laying and recycling plastic sheets during rain and snow simplifies loading and unloading operations; the dual protection of luggage against moisture and scratches directly improves passenger baggage transportation satisfaction and overall service quality.

[0024] The grating plate assembly features a detachable design, facilitating partial replacement or overall cleaning and maintenance, ensuring long-term effective drainage and reducing equipment maintenance costs. Attached Figure Description

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-4 As shown, see details. Figure 1 and Figure 2 This utility model proposes a civil aviation bulk cargo baggage trailer with waterproof function, including a cargo box body 1 and wheels 2. The feature is that a plurality of mutually detachable and fixedly connected grid pad assemblies 3 are laid at the bottom of the cargo box body 1, and bulk cargo baggage is placed on the grid pad assemblies 3.

[0033] At least one drainage hole is provided at the bottom of the carriage body 1.

[0034] In this embodiment, the carriage body 1 is a metal frame structure with side panels and a floor plate. Multiple grille pad assemblies 3 are tightly laid on the floor plate inside the carriage body 1. Adjacent grille pad assemblies 3 are connected and fixed to each other by a detachable fixing connection. Common connection methods include:

[0035] Snap-fit ​​connection: Protruding snaps and corresponding slots are provided on the edge of the grid pad assembly 3.

[0036] Pin / bolt connection: Use pins or quick-release bolts to pass through the reserved holes on the edge of the adjacent grid pad assembly 3.

[0037] In this embodiment, a snap-fit ​​connection is preferred. The snap-fit ​​connection is existing technology and will not be described in detail here.

[0038] At least one drainage hole is provided on the floor of the carriage body 1, located below the grille pad assembly 3. In rainy or snowy weather, rainwater or snowmelt will drip down through the perforated structure of the grille pad assembly 3. The dripping water collects in the space between the carriage's metal floor and the grille pad. The collected water flows directly out of the carriage through the drainage hole on the floor, preventing water accumulation at the bottom of the carriage.

[0039] In practice, 10 drainage holes are usually opened at intervals on the floor of the carriage to ensure rapid and thorough drainage and avoid local water accumulation.

[0040] In this embodiment, see Figure 3 Each of the grid pad assembly 3 includes a grid unit 31 and a support assembly 32;

[0041] Two adjacent grid units 31 are detachably and fixedly connected, and a grid unit 31 is fixed on the upper surface of the support assembly 32.

[0042] The support component 32 is arranged circumferentially along the outer edge of the grid unit 31. The circumferentially arranged support component 32 is arranged in an array that is proportionally reduced from the edge to the center of the grid unit 31 at a set interval.

[0043] In this embodiment of the civil aviation bulk cargo trailer, the grating pad assembly 3 adopts a layered structural design. Each grating pad assembly 3 is composed of a grating unit 31 and a support assembly 32. The grating unit 31 serves as the surface layer that directly supports the luggage, and its permeable grating structure allows liquid to pass through vertically. Adjacent grating units 31 are connected by a detachable fixing method, such as using the buckles, pins, or bolts described above to achieve quick assembly and disassembly.

[0044] The support component 32, serving as the core support structure, is located within the interlayer space of the grid unit 31. Its upper and lower surfaces are respectively fixedly connected to one grid unit 31, forming a stable composite load-bearing body. The layout of the support component 32 strictly follows the principle of spatial optimization: after being set circumferentially along the outer edge of the grid unit 31, it is distributed in an array that decreases proportionally from the edge towards the center at predetermined intervals. This gradient layout ensures both the overall structural strength and creates a downward flow path for water.

[0045] In this embodiment, the grid unit 31 is a rectangular flat plate structure. The support assembly 32 is arranged in a multi-level concentric rectangular frame array, specifically including the following features:

[0046] Within the rectangular plane of a single grid unit 31, support components 32 are connected end-to-end along the circumferential edge of the rectangle to form a closed rectangular frame structure. This frame array is arranged in a nested manner from the outside in, i.e.:

[0047] The first-level frame fits the outer edge contour of the grid unit 31. The second-level frame is located inside the first-level frame, and its four sides are parallel to the first-level frame. The third-level frame is located inside the second-level frame, and so on to form a multi-level nested frame.

[0048] During rain or snow, liquid enters the array gaps of the support assembly 32 through the gaps in the upper grille unit 31 and is eventually discharged outside the vehicle through the drainage holes. The double-layer grille unit 31, combined with the gradient support structure, significantly enhances the pressure resistance and drainage efficiency of the pad.

[0049] See Figure 3 In this embodiment, the grille unit 31 includes a frame 311 and grille strips 312;

[0050] The frame 311 is fixed to the outermost support component, and the inner surface of the frame 311 is fixed to a plurality of grid strips 312, which are arranged in parallel and at an angle.

[0051] If the grille bars 312 are set horizontally or vertically, when luggage is placed into the carriage in the conventional way, the luggage wheels are easy to get stuck between two adjacent grille bars 312. Therefore, in this embodiment, the grille bars 312 are set at an angle to avoid this problem, avoid damage to the luggage wheels, and facilitate the handling of luggage. In order to further avoid the problem of luggage wheels getting stuck, in this embodiment, the interval between two adjacent grille bars 312 is smaller than the width of the luggage wheels.

[0052] See Figure 4In this embodiment, the support component 32 is provided with multiple slots 321 at intervals. By providing slots 321, the weight of the support component can be reduced and the processing cost can be reduced. The slots 321 are semi-circular through slots, which can improve the flow effect of liquid and prevent the entire long strip-shaped support component 32 from blocking the liquid.

[0053] In this embodiment, the carriage body 1 has a cavity for accommodating loose cargo luggage, and the carriage body 1 has a top opening 5 communicating with the cavity, through which loose cargo luggage can be taken out and put in the cavity. The carriage body 1 is provided with a waterproof cloth, which is used to cover the top opening 5.

[0054] The two side panels along the length of the carriage body 1 are provided with side openings 6 that communicate with the cavity and the top opening 5. Both sides of the carriage body 1 are provided with opening and closing doors corresponding to the side openings 6. The opening and closing doors can switch between open and closed states. When the opening and closing doors are in the open state, loose cargo luggage can be taken out and put into the cavity through the side openings 6. When the opening and closing doors are in the closed state, the loose cargo luggage in the cavity is contained.

[0055] The main body of the carriage 1 is formed by welding metal frames and panels, with an internal cavity for accommodating loose cargo and luggage.

[0056] A through-type top opening 5 is opened at the top of the cavity, with the opening width covering more than 50% of the width of the carriage, to ensure the feasibility of vertically hoisting large luggage.

[0057] In this embodiment, the opening and closing door is preferably a sliding door. The sliding door is provided with a waterproof sealing strip on the inner side. When closed, it is compressed and deformed to achieve a seal. The structure of the sliding door is existing technology and will not be described in detail in this embodiment.

[0058] The waterproof cloth can be fixed to the carriage body 1 with Velcro, achieving both fixation and waterproofing.

[0059] In addition, the waterproof cloth can also be fixed to the carriage body 1 in other ways, specifically: guide rails that match the cross-sectional shape are installed on both sides of the top opening 5, and the waterproof cloth passes through the guide rails and moves along the guide rails.

[0060] Specifically, in this embodiment, the top plate is set to be arc-shaped, that is, the cross-sectional shape of the top opening is arc-shaped. A fixed round rod is fixed on the cross-section as a guide rail. Multiple holes are opened on the waterproof cloth, and the holes are passed through the round rod. One end of the waterproof cloth is fixed to the box body 1, and the other end can move to realize the opening and closing of the waterproof cloth.

[0061] In this embodiment, the grille pad assembly 3 that contacts the opening and closing door is fixed to the carriage body 1 by a detachable connecting assembly.

[0062] The detachable connection components may include stainless steel self-locking screws, galvanized washers and nuts. The screws pass through the grille unit 31 and are locked to the car floor to prevent the grille unit 31 from falling off when moving luggage.

[0063] In this embodiment, the grille pad assembly 3 is made of plastic.
