Description

Technical Field

[0001] This application belongs to the field of refueling device design, and specifically relates to a flexible connection device for refueling device structure. Background Technology

[0002] The refueling unit structure is installed on the inclined platform floor structure. Since the inclined platform structure will undergo large deformation under aircraft pressurization, it will be directly transmitted to the refueling unit structure. Because the refueling unit structure itself cannot withstand the deformation caused by this load, a flexible connection structure needs to be set in the refueling unit structure to eliminate the impact of passive load. Summary of the Invention

[0003] The purpose of this application is to provide a flexible connection device for the refueling device structure to solve the problem of increased passive load when the deformation of the existing refueling device structure and the cargo bridge structure is inconsistent.

[0004] The technical solution of this application is: a flexible connection device for a refueling device, including a first flange, a second flange and a flexible rubber component; the flexible rubber component is a cylindrical structure, the first flange and the second flange are both L-shaped in cross-section and are symmetrically arranged through the middle of the flexible rubber component, and the two ends of the flexible rubber component are respectively attached to the outer walls of the first flange and the second flange.

[0005] Preferably, the flexible rubber component has multiple sets of inner ring grooves evenly formed along the axial direction, and each inner ring groove is provided with a complete steel ring.

[0006] Preferably, the flexible rubber component has annular protrusions on both sides corresponding to the steel ring.

[0007] Preferably, the flexible rubber component has rectangular cross-section fixing grooves at both ends, and annular support rings are provided in the fixing grooves. The inner wall of the support rings corresponds to the outer wall of the first flange and the second flange.

[0008] Preferably, the support ring is made of aluminum.

[0009] Preferably, the two ends of the flexible rubber component are fixed to the first flange and the second flange by adhesive bonding.

[0010] Preferably, the two ends of the flexible rubber component are fixed to the first flange and the second flange by bolts.

[0011] The flexible connection device for the refueling device in this application transfers refueling power through the cargo bridge floor structure to a flexible rubber component via a flange. The flexible rubber component is a flexible structure that can effectively absorb passive loads, thereby reducing the increase in structural weight and preventing structural deformation and releasing passive loads. At the same time, the structure is simple and stable, lightweight, and can be used by connecting the first and second flanges with corresponding bolts, which is quite convenient.
