Description

Technical Field

[0001] This invention relates to the field of airport ground support equipment, and more particularly to a navigation light maintenance work container. Background Technology

[0002] With the rapid development of the civil aviation industry, the number of airport navigation lights has increased significantly during the design and construction process. In particular, the density and technological sophistication of pavement-embedded centerline lights are constantly improving. Airport operational safety also places higher demands on the integrity and reliability of the lighting system. Currently, the inspection and maintenance of most airport navigation lights must be carried out during short downtime periods after daily flights end. This timeframe is extremely tight. In rainy, snowy, stormy, or extremely cold weather, the maintenance environment deteriorates, significantly shortening maintenance time and sometimes forcing maintenance to be suspended. This greatly hinders the already urgent lighting maintenance work, indirectly affecting the airport's operational capacity and takeoff and landing safety.

[0003] Against this backdrop, a mobile, scientifically constructed, well-equipped, and fully functional lighting maintenance cabin was designed and manufactured to overcome the impact of harsh weather and improve the working environment for personnel. Within the enclosed cabin, tasks such as drilling, installing, applying adhesive, and wiring tests for embedded lighting fixtures were completed. It could also be placed at the location of the transformer isolation box to complete tasks such as primary cable testing and primary connector fabrication. Summary of the Invention

[0004] In view of the above problems, the purpose of this invention is to provide a navigation light maintenance work container. The present invention adopts the following technical solution:

[0024] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown in the figure, this embodiment discloses a navigation light maintenance work cabin, including a movable cabin body 1, a work opening 2, a sealing device 3, and a ring-shaped curtain 8.

[0026] The cabin 1 is equipped with a doorway 6 and a window 7. The interior dimensions of the cabin are 2.5 meters long and 2 meters wide to accommodate construction tools and equipment. The work opening 2 is centrally located at the rear of the cabin 1, with 40-centimeter-wide passageways on both sides for personnel to stand and pass through. The interior height is 1.9 meters, allowing personnel to stand freely.

[0027] Two sets of unpowered wheels 4 are installed at the bottom of the cabin 1, and a towing device 5 is installed at the front of the cabin 1. The towing device 5 is connected to the maintenance vehicle, and the work cabin is towed to the work area by the maintenance vehicle. After arriving at the designated position, the wheels 4 are locked by the parking device on the cabin 1. The work cabin can be detached from or hooked to the towing vehicle through the towing device 5, which is both flexible and mobile and can complete maintenance work independently.

[0028] The cabin 1 consists of a frame 101 and an insulated wall panel 102 installed on the frame 101. The frame 101 is made of welded steel profiles, and the insulated wall panel 102 is made of sandwich rock wool insulation board, which has good structural strength and thermal insulation performance.

[0029] The working port 2 is equipped with an openable sealing device 3, which includes a metal frame 301. The metal frame 301 is fixed to the working port 2, and a removable cover plate 302 is provided inside the metal frame 301.

[0030] The cover plate 302 can be made of transparent polycarbonate sheet. Its lightweight design provides sufficient load-bearing strength for personnel and equipment within the hold, while also facilitating disassembly and operation. The transparent material allows for easy observation and positioning of the hold floor. The cover plate 302 features a recessed lifting handle 303 to maintain a flat floor in the hold. Hooks are located on the rear wall of the hold for the cover plate 302 to be lifted and secured vertically against the wall, minimizing space occupancy within the hold.

[0031] The circular curtain 8 is set in the area corresponding to the working opening 2. The circular curtain 8 can be a foldable and telescopic structure, which is convenient to put up and put down.

[0032] In this embodiment, the upper and lower ends of the annular curtain 8 are sealed with metal plates. An upper frame 801 is fixed to the upper end, and a lower frame 802 is fixed to the lower end. The upper frame 801 is slidably connected to a vertically arranged guide rail bracket 803, which is fixed inside the cabin 1. Normally, the annular curtain 8 is folded up and lifted by hooks to hang on the upper frame 801, and the entire annular curtain 8 slides up into the cabin 1.

[0033] The retractable annular curtain 8 does not impede the movement of the cabin. In use, the annular curtain 8 is first slid down to the work opening 2. At this point, the hook is removed, and the lower edge 802 of the annular curtain 8 rests on the ground under its own weight, forming a temporary enclosed environment. Workers can then work inside the annular curtain 8, avoiding the impact of severe weather. After construction is completed, the annular curtain 8 is retracted before the cover plate 302 is replaced.

[0034] In this embodiment, a slider is fixed on the upper frame 801, and a vertically arranged slide rail is fixed on the guide rail bracket 803. The slider is slidably connected to the slide rail, and a locking device is provided on the slider. When the slider slides to the correct position, it is fixed by the locking device. Specifically, the locking device can be a bolt, which is threaded onto the slider. The bolt presses against the slide rail to fix the slider.

[0035] The cabin 1 is equipped with a generator and distribution box to provide power for lighting, heating, and operations. Radiator coils and three-way valves are installed on the inner walls, connected to the generator exhaust. In extremely cold weather, the generator exhaust is used to heat the cabin before being discharged outside, resulting in energy conservation and environmental protection. The exterior is painted with yellow reflective paint, and aviation obstruction lights are installed on the top, which are turned on when in use. Floodlights are installed around the perimeter of the cabin to allow personnel inside to observe the work area through the windows for any items left behind and to conduct exit checks.

[0036] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
