Problems solved by technology

[0004] Since the current test method is: multiple testers simultaneously rotate the screws between the load base and the load rotating body around the load rotating body, so that the load rotating body moves up and down in translation, and the strength of each tester's rotation and the speed cannot be exactly the same, so it is impossible to ensure that the posture of the load rotating body remains unchanged during the lifting process. This method requires a lot of work and wastes labor.

Abstract

The invention discloses a synchronous lifting device for bellows couplers, which comprises: a frame; a load carrying mechanism, the load carrying mechanism is arranged in the frame; One end of the lifting mechanism is fixed on the frame, and the other end is fixed below the load-bearing mechanism; the operating mechanism is connected with the link lifting mechanism to drive the link lifting mechanism up and down, thereby driving the load-bearing mechanism Ascent and descent. A load driving device is also disclosed. The synchronous lifting device of the bellows coupler of the present invention only needs one tester to operate the operating mechanism to realize the synchronous lifting around the bellows, ensure the lifting movement of the load rotating body, and keep the posture unchanged during the lifting process, and protect the falling plug, which can improve Work efficiency ensures the safety of equipment and personnel; and has the advantages of simple structure and easy implementation, which liberates labor and improves work efficiency.

Description

technical field [0001] The invention relates to a lifting device, in particular to a synchronous lifting device used for ground test experiments of a load rotating body and a load base. Background technique [0002] Many satellite payloads have on-orbit mechanical scanning functions. In order to protect the mechanical scanning drive mechanism and ensure the reliability and on-orbit life of the scanning drive mechanism, the scanning drive mechanism is often free from force during the launch phase, and the scanning drive mechanism is installed on the load base. Therefore, the bellows coupling is often used to connect the load rotating body and the scanning drive mechanism. In the launch stage, the load base and the load rotor are fixed separately, so as to avoid the mutual influence of the vibration response of the load rotor and the load base, which not only protects the scanning drive mechanism inside the load base, but also protects the inner part of the load rotor. of pre...
