Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of aviation equipment, and particularly relates to a cross beam positioning plate for supporting during aircraft modification. BACKGROUND

[0002] During the conversion of a passenger aircraft into a cargo aircraft, the middle section of the longitudinal beam is prone to twisting when the floor beam is installed due to the long span of the longitudinal beam, which affects the subsequent work due to incorrect spacing between the cross beams. There is currently no suitable tool to prevent the twisting of the longitudinal beam, and manual measurement is required to ensure the correct spacing between the cross beams in the middle section during installation. SUMMARY

[0003] The utility model solves the technical problem of providing a cross beam positioning plate that can effectively ensure the spacing requirements between each cross beam.

[0004] The utility model solves the technical problem by the following scheme: a cross beam positioning plate is installed on the cross beam with seat rails, the cross beam is fixed on the longitudinal beam, and the cross beam is provided with rail positioning holes. The cross beam positioning plate comprises at least one longitudinal positioning plate and at least two transverse positioning plates. The longitudinal positioning plate longitudinally spans at least four cross beams. The length of the longitudinal positioning plate is designed according to the span of the cross beams. The longitudinal positioning plate is fixed to each cross beam. The number of transverse positioning plates is the same as the number of middle cross beams after removing the end cross beams of the cross beams spanned by the longitudinal positioning plate. Each transverse positioning plate corresponds to a middle cross beam. One end of the transverse positioning plate is fixed to one side of the longitudinal positioning plate close to the longitudinal beam. The other end of the transverse positioning plate is fixed to the cross beam on the other side of the longitudinal beam. The position of the installed transverse positioning plate is higher than that of the longitudinal beam.

[0005] The longitudinal positioning plate installed on the cross beam fixes the spacing between the cross beams, thereby ensuring the spacing requirements between each cross beam. The transverse positioning plate spans the longitudinal beam and the longitudinal rail on the longitudinal beam in a bridging manner to simultaneously connect the seat rails on the upper and lower parts, thereby making the installation more secure.

[0006] On the basis of the above-mentioned scheme, the positioning pin and the locking device are further included. The longitudinal positioning plate is provided with a longitudinal plate mounting hole and a longitudinal plate positioning hole corresponding to the rail and the rail positioning hole of each cross beam spanned by the longitudinal positioning plate. The other end of the transverse positioning plate is provided with a transverse plate mounting hole and a transverse plate positioning hole corresponding to the rail and the rail positioning hole of the cross beam on the other side of the longitudinal beam. The longitudinal positioning plate and the transverse positioning plate are connected by the positioning pin so that the longitudinal plate positioning hole and the transverse plate positioning hole correspond to the rail positioning hole. The locking device is installed on the rail through the longitudinal plate mounting hole and the transverse plate positioning hole.

[0007] Further, the locking device comprises a butterfly nut, a screw rod, and a locking nut. The bottom of the screw rod is provided with a circular base suitable for the rail sliding groove. The top of the screw rod penetrates the locking nut and is fixed to the butterfly nut by a spring pin.

[0008] The butterfly nut facilitates workers to tighten the locking device by hand.

[0009] On the basis of the above scheme, at least two groups of cross beam positioning plates are included, the head and tail of the longitudinal positioning plates of each group of cross beam positioning plates correspond, and the longitudinal positioning plates are installed on the cross beams on both sides of the longitudinal beams in a staggered manner.

[0010] The spacing requirements between each cross beam are more reasonably ensured through the staggered installation manner.

[0011] The utility model has the advantages that: the utility model has simple structure and is convenient to install, the spacing requirements between each cross beam are ensured through installation on the cross beams, the distortion of the middle section is effectively solved, manual measurement and measurement errors in the working process are avoided, the working efficiency is increased, and the installation accuracy is improved.
