a hanging device

Abstract

The invention belongs to the field of space product application and particularly relates to a hoisting device. The hoisting device comprises a crossbeam, a hoisting connecting piece, a sliding sleeve,a right stop block, a screw, a nut and a left stop block. The crossbeam is of a hollow structure, the left stop block and the right stop block are contained in the two sides in the crossbeam, the nutis in threaded connection with the screw, the nut and the screw are contained in the crossbeam together, and the two ends of the screw are rotationally connected with the left stop block and the right stop block; the crossbeam is sleeved with the sliding sleeve connected with the nut and the hoisting connecting piece, and through rotation of the screw, the nut can drive the sliding sleeve to conduct reciprocating motion on the crossbeam; and both the left stop block and the right stop block are connected with coupling screws located outside the crossbeam, and the coupling screws on the two sides are connected with a space product. By the adoption of the hoisting device, product hoisting adjustment can be convenient, in the horizontal movement process, the accuracy in the vertical direction is not changed, and the problem of mutual interference generated in multi-directional repeated adjustment in the general assembly process of the product is solved.

Description

technical field [0001] The invention belongs to the field of space products, in particular to a hanging device. Background technique [0002] At present, with the development of aerospace technology, the application of space products has become increasingly widespread. It is an essential requirement for space products to simulate the weightless environment of space for final assembly and testing on the ground. The gravity-free adjustment system plays a vital role in aerospace products with long arms and large thin-walled parts. [0003] Space products work in a weightless environment when they work in space. In order to do corresponding tests on the ground, as well as in the final assembly process, a non-gravity adjustment system is required to counteract gravity, especially in the final assembly process. In the gravity-free adjustment system, there is a device that needs to connect the space product and the adjustment system slide rail, which is the product hanging devic...

AI Technical Summary

Problems solved by technology

[0004] At present, there are various problems in the process of using the hanging device. For example, during the final assembly process of the product, it is necessary to repeatedly adjust its various postures, but the current hanging adjustment is inconvenient; in the process of hanging and product installation, due to the need Considering the insulation factor, it makes the installation process inconvenient, and it is easy to have redundant objects fall off; coupling disturbance occurs when adjusting in different directions, which makes the adjustment accuracy change repeatedly and affects the adjustment efficiency
