Automatic one-dimensional-equilibrium adjusting lifting tool for spacecraft

Abstract

The invention discloses an automatic one-dimensional-equilibrium adjusting lifting tool for a spacecraft. The lifting tool comprises a main lifting beam, a control module, a power supply, a driving motor, a tilt angle sensor, a balance weight moving mechanism, a stretching auxiliary lifting beam, a tension sensor and a lifting ring assembly, wherein the control module, the power supply, the driving motor, the tilt angle sensor and the balance weight moving mechanism are arranged in the main lifting beam; one end of the stretching auxiliary lifting beam is connected with the main lifting beam, and the other end of the stretching auxiliary lifting beam is connected with the tension sensor and the lifting ring assembly. By automatically adjusting the equilibrium position by virtue of a balance weight, the lifting tool has the characteristics of short adjusting time, high adjusting precision, adjustability in bearing range, good universality and the like, the safe, efficient and high-precision mounting and dismounting work of a heavy device can be realized, the labor cost is saved, the working efficiency is increased, the requirement of the ever-developing spacecraft on the automatic technical level of a final assembly is met, and the automatic level of the final assembly of the spacecraft is improved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft hoisting and installation, and in particular relates to a one-dimensional balance automatic adjustment hanger for spacecraft. Background technique [0002] With the development of a new generation of spacecraft at any time, the disassembly and assembly of large-mass and large-volume equipment in the cabin and large parts such as cameras are frequent. Since the existing tooling equipment cannot directly disassemble and assemble large-weight instruments and equipment in the vertical installation surface, Therefore, the disassembly and assembly of this type of equipment is currently mainly carried out by manual or mechanical auxiliary tooling using the following two methods: (1) Decompose the large cabin section, and after completing the disassembly and assembly of the equipment in the single cabin state, re-install the large cabin (2) Hoist the spacecraft to the turntable, and disassemble it when...

AI Technical Summary

Problems solved by technology

[0003] The existing methods of disassembly and assembly relying on manual or mechanical auxiliary tooling have the following prominent problems: (1) low assembly accuracy, complicated operation process, high operational risk, and the risk of product bumping and damage; (2) the role of auxiliary tooling Not obvious, highly dependent on operating experience, and difficult to guarantee assembly quality; (3) Tooling equipment is not universal, one instrument and one set of tooling cannot be reused, and economic benefits are poor; (4) There are many operating steps, human resources are occupied, and production Efficiency is greatly affected

[0004] Due to the above-mentioned deficiencies in the existing auxiliary tooling, there is an urgent need for safe and efficient disassembly tools to solve the problems encountered in the assembly of spacecraft, such as difficulty in disassembling and disassembling large-scale and large-volume equipment, high operational risks, low assembly accuracy, and operational steps. Complexity, high human and economic costs and other problems
