Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The aircraft tank is a circular structure with a diameter of 900mm, a straight end length of 1040, and a radius of 450mm at both ends. The structural space for the aircraft to install the tank has a diameter of 940mm and a length of about 2500mm. There are frame beam structures at different intervals inside the aircraft. It can be seen that the space reserved for the installation of the tank by the aircraft is very narrow. At the same time, aircraft tanks are very heavy. Installing such a large tank safely and quickly was difficult. It is required that the storage tank installation device occupies a small space and has a strong displacement adjustment capability to achieve precise alignment during the storage tank installation process.

Abstract

The invention discloses a double-guide-rail storage tank mounting device and method, and belongs to the technical field of structure design. A storage tank is placed on L-shaped guide rails, the guide rails are fastened to a structure through fixing pieces, displacement adjustment in the longitudinal and transverse directions perpendicular to lead screws is achieved through lead screw structures, and meanwhile, displacement adjustment in the direction of the guide rails is achieved through bearing structures mounted on the storage tank. In addition, the guide rails are completely fixed through threaded rods after being adjusted in place. The storage tank mounting method is suitable for connected mounting of the storage tank and the structure in a narrow space, the position adjustment requirement during storage tank mounting is met, and meanwhile, the requirement for the mounting operation space is also met.

Description

technical field [0001] The invention relates to a tank installation device and an installation method thereof, in particular to a tank installation tooling scheme for an on-orbit aircraft, and belongs to the technical field of structural design. Background technique [0002] Storage tanks are widely used in the aerospace field. According to different structural forms, foreign countries have proposed various schemes on the connection form of storage tanks of spacecraft, and have been successfully used in model products. For example, the patent "Installation Device and Implementation Method of Thin-walled Lightweight Integrated Storage Tank" proposed by Shanghai Satellite Engineering Research Institute adopts horizontal frame and arched frame, and is only proposed for the structure of loading 4 storage tanks, which is suitable for specific storage tanks Connect and install. Beijing Control Engineering Research Institute's patent "A Tank Installation Structure Applicable to Tr...
