Embodiment Construction

[0010] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0011] Such as figure 1 Shown is a schematic diagram of a satellite load single-point vertical suspension device of the present invention, the device is composed of a suspension ring 1, a main span beam 2, a lock nut 3, a protection insert 4, a main bearing strap 5, and a protection strap 6, and the vertical load bearing Suspender 7, suspender locking device 8 form. Three lifting rings 1 are installed at the lifting points of the main span beam 2 to connect the suspenders. The protective inserts 4 are inlaid at both ends of the main span beam 2 to protect the main load-bearing cables and reduce the shear force. The lock nut 3 is used to Fix the vertical hook ring 1 in the middle, and the above-mentioned part is a structural part. The main load-bearing sling 5 mainly carries the weight of the payload of the satellite, and is lifted by connecting the shackle a...

Abstract

The invention puts forward a satellite load single-point vertical hoisting device, which comprises a main span beam, three hoisting rings, protection insert blocks, and a locking nut. The three hoisting rings are mounted at hoisting positions of the main span beam. The protection insert blocks are inlaid at two ends of the main span beam, and the locking nut is used for fixing the middle vertical hoisting ring. A load-bearing strap is connected to a load through a shackle and a transfer tooling to be hooked on a hook for realizing hoisting. A vertical load-bearing strap is in connection with the middle hoisting ring and the hook and bears the weight of the main span beam. A protection strap is fixed to the main span beam through strap locking instruments, and has the other end fixed on the hook, thus preventing the damage brought by product overturn and main span beam inclination to the product. The device provided in the invention solves the single-point hoisting and transferring problems of a satellite payload in a vertical state, and has the advantages of integration, simple operation and high efficiency. And the beneficial effects of simple structure, convenient operation, easy maintenance, safe hoisting, and convenient use can be achieved.

Description

technical field [0001] The invention relates to the technical field of satellite assembly, in particular to a satellite load single-point vertical hanging device, which is used in satellite testing, transfer and packing. Background technique [0002] With the development of aerospace technology, the functions of the satellite payload system have become more and more complex, and the number of rotating parts has increased. The scanning motion of the rotating parts of the payload will produce periodic attitude disturbances during orbital flight. According to the design of the dynamic balance test plan, it is necessary to carry out tests under the complete machine state such as the complete dynamic balance test and the disturbance torque test. The lifting and transfer during the test are the key links to ensure the safety of the product and the successful completion of major tests. [0003] Due to the requirements of satellite installation, the usual method is to place the prod...
