Abstract[English]
The present application relates to the technical field of aircrafts, and discloses an aircraft ground towing trailer. The aircraft ground towing trailer of the present application is used for lifting and towing an aircraft, and comprises a towing portion and a frame portion capable of moving horizontally and up and down by means of the towing portion. The frame portion can enter and exit an area below the aircraft under the action of the towing portion, and a plurality of connecting devices on two sides of the frame portion can individually move close to and connect to a landing gear of the aircraft. The aircraft ground towing trailer of the present application can conveniently enter the area below the aircraft, especially in the case where the ground area is uneven, the landing gear of the aircraft is supported and connected by means of the movable connecting devices, so as to complete the towing work of the aircraft.[French]
La présente demande se rapporte au domaine technique des aéronefs et concerne une remorque de tractage au sol d'aéronef. La remorque de tractage au sol d'aéronef de la présente demande est utilisée pour lever et tracter un aéronef, et comprend une partie de tractage et une partie cadre pouvant se déplacer horizontalement, vers le haut et vers le bas au moyen de la partie de tractage. La partie cadre peut entrer et sortir d'une zone au-dessous de l'aéronef sous l'action de la partie de tractage, et une pluralité de dispositifs de liaison sur deux côtés de la partie cadre peuvent se déplacer individuellement à proximité et se raccorder à un train d'atterrissage de l'aéronef. La remorque de tractage au sol d'aéronef de la présente demande peut entrer commodément dans la zone au-dessous de l'aéronef, en particulier dans le cas où la zone de sol est irrégulière, et le train d'atterrissage de l'aéronef est supporté et relié au moyen des dispositifs de liaison mobiles, de façon à achever le travail de tractage de l'aéronef.[Chinese]
