Synchronous lifting device of corrugated pipe connector and load driving device

Abstract

The invention discloses a synchronous lifting device of a corrugated pipe connector. The synchronous lifting device comprises a rack, a load bearing mechanism, a connecting rod lifting mechanism and acontrol mechanism, wherein the load bearing mechanism is arranged in the rack; the connecting rod lifting mechanism is arranged between the rack and the load bearing mechanism, one end of the connecting rod lifting mechanism is fixed to the rack, and the other end of the connecting rod lifting mechanism is fixed below the load bearing mechanism; and the control mechanism is connected with the connecting rod lifting mechanism and used for driving the connecting rod lifting mechanism to ascend and descend, and therefore the load bearing mechanism is driven to ascend and descend. The invention further discloses a load driving device. According to the synchronous lifting device of the corrugated pipe connector, synchronous lifting of the periphery of a corrugated pipe can be achieved only byoperating the control mechanism by one tester, and lifting motion of a load rotating body is guaranteed; the posture is not changed in the lifting process, a falling plug is protected, the working efficiency can be improved, and the safety of equipment and personnel is guaranteed; and the synchronous lifting device has the beneficial effects of being simple in structure and easy to achieve, the labor force is liberated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an elevating device, in particular to a synchronous elevating device used for ground testing experiments of a load rotating body and a load base. Background technique [0002] Many satellite payloads have an on-orbit mechanical scanning function. In order to protect the mechanical scanning drive mechanism, ensure the reliability and on-orbit life of the scanning drive mechanism, the scanning drive mechanism is often not subjected to force during the launch phase, and the scanning drive mechanism is installed on the load base. Inside the seat, bellows couplings are often used to connect the load rotating body and the scanning drive mechanism. The load base and the load rotating body are fixed separately during the launch phase, thus avoiding the mutual influence of the vibration response of the load rotating body and the load base, and protecting the scanning drive mechanism inside the load base as well as the load rotating body...

AI Technical Summary

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.
