[0002] After the external equipment of a certain type of aircraft is removed from the aircraft, it needs to be stored in a special container. However, the existing container welding and manufacturing method uses manual support, which has problems such as deviations in the verticality of the bottom beams, overall welding distortion and deformation of the container, and inability to open the door properly. In some cases, safety accidents may even occur due to manual support. Utility Model Content

[0003] This utility model provides a special welding fixture for aircraft external equipment container, which facilitates the welding and forming of the door ends on both sides of the container chassis top plate and side plate, ensuring that all beams at the bottom are vertical and without deviation, and preventing problems such as twisting deformation and inability to open the doors properly during the overall welding of the container. It achieves the goals of easy support and welding of the various plates and beams in the container assembly, control of deformation, ensuring dimensional accuracy, and reducing personnel requirements.

[0004] The present invention adopts the following technical solution:

[0005] A special welding fixture for aircraft external equipment container, the special welding fixture includes a base assembly 1, a ladder 2, a welding frame 3, an upper platform and a ground platform 4.

[0006] The ground platform 4 is used to provide support for the entire special welding fixture. It is an integrated platform structure or a combination of multiple platform structures, used to ensure the flatness of the container chassis and control the amount of deformation.

[0007] The welding frame 3 is a rectangular frame structure with positioning posts 3-1 at its four corners. The main body of the positioning posts 3-1 is H-steel, and a base 3-2 is set at the bottom. It is fixed and locked on the bottom platform 4 by platform positioning pins to ensure that the welding frame 3 will not tip over. The adjacent positioning posts 3-1 are fixedly supported by square tubes. To ensure the stability of the welding frame 3, multiple square tubes of different heights are fixed between adjacent positioning posts 3-1.

[0008] The upper platform is U-shaped and is fixed to the upper part of the welding frame 3 and surrounds the welding frame 3 to form an upper operating platform. The upper platform is composed of square tubes to form the platform bottom frame. After steel plates are installed inside the platform bottom frame, anti-slip aluminum plates are riveted on them. The platform bottom frame is fixed to the positioning column 3-1 of the welding frame 3. Several square tubes are fixed between its bottom and the welding frame 3 to achieve a supporting function. Side guardrails are fixed to the outside of the upper platform. The side guardrails are welded from steel pipes.

[0009] A ladder 2 is installed between the upper platform and the ground. The bottom of the ladder 2 is supported on the ground by a foot assembly 1, and the upper end is fixed to the bottom frame of the upper platform. Handrails are provided on both sides and are fixedly connected to the side railings of the upper platform. The foot assembly 1 includes a lower base plate 1-1 and a base plate support rod 1-2 fixed on the base plate 1-1. The base plate 1-1 is covered with a rubber cup 1-3 to increase the friction between it and the ground. The upper end of the base plate support rod 1-2 is fixed to the bottom of the ladder 2.
