According to the different positions of the parked aircraft and the carried tooling, two types of welding platforms, the heavy welding platform 4 and the three-dimensional flexible welding platform 2, are selected, and the heights are the same. Among them, the heavy welding platform 4 is arranged in a triangular shape and is used for bearing the weight of the aircraft body, and the three-dimensional flexible welding platform 2 is arranged below the aircraft nose. After the positions of the heavy welding platform 4 and the three-dimensional flexible welding platform 2 are determined, the square tube 3 is used for fixedly connecting the platforms to form a rectangular platform. The three-dimensional flexible welding platform 2 is arranged on one side edge of the rectangular platform, and a plurality of slow walking platforms 1 are arranged on the three-dimensional flexible welding platform 2. The aircraft is pulled to the appropriate position of the rectangular platform by means of the slow walking platforms 1.

[0006] The heavy welding platform 4 and the three-dimensional flexible welding platform 2 are integrally cast. The outer surfaces of each heavy welding platform 4 and three-dimensional flexible welding platform 2 are uniformly and spacedly provided with a plurality of mounting holes, and the bottom surfaces are uniformly provided with a plurality of level adjustment points 5. The level adjustment points 5 are mounted in the mounting holes at the top and are provided with foundation bolts at the bottom. The foundation bolts are adjusted through the mounting holes, and the ground platform positioning tool is adjusted to be horizontal as a whole.

[0007] The utility model has the advantages that the utility model provides a horizontal installation platform for damaged aircraft repair tooling and aircraft, can keep the aircraft in a horizontal parking state during the repair process, and can clamp and fix the replacement components at the installation positions during the disassembly and replacement of the aircraft cabin components, and the positions will not deviate due to external force.
