On-orbit monitoring device of rope tension for spacecraft

Abstract

The invention discloses an on-track monitoring device for tension of a spacecraft rope. The device comprises an angular position sensor, a gear rack transmission assembly, a microswitch, an installation sleeve, a compression spring, a push rod and a roller assembly, wherein the rope rotates around the roller assembly; the roller assembly is tightly pressed by the compression spring through the push rod; the compression spring is mounted in the installation sleeve; a first end of the push rod slides inside the installation sleeve; an end part of a second end of the push rod is connected with the roller assembly; the roller assembly performs translational motion due to the change of the tension on the rope; the gear rack transmission assembly changes the translational motion of the roller assembly into rotation; the angular position sensor measures the rotation angle of the gear rack transmission assembly; and the microswitch triggers limit signals. According to the device, the problem that the tension of a rope part on the spacecraft requires to be monitored accurately is solved. At the same time, the device has the advantages of light mass, simple adjustment, small size, high security, low power consumption and the like, and the reliability and the applicability of on-track monitoring of rope tension are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of rope mechanisms used for spacecraft movement, in particular to a rope tension on-orbit monitoring device for spacecraft. Background technique [0002] With the development of spacecraft technology, the application of moving rope components on spacecraft is becoming more and more extensive, and devices with the requirement of accurately monitoring the tension of ropes are also produced. The general general commercial force sensors at home and abroad mainly have the following problems: 1) Most of the force sensors require relatively complicated conditioning circuits, and the weight and volume are large; [0003] 2) It is generally used as the ground, and the reliability of space use and the impact of the environment on it need special test verification; [0004] These problems limit the use of rope tension monitoring technology on spacecraft such as spacecraft, and even limit the use of related moving part...

Problems solved by technology

The general general commercial force sensors at home and abroad mainly have the following problems: 1) Most of the force sensors require relatively complicated conditioning circuits, and the weight and volume are large;

[0003] 2) It is generally used as the ground, and the reliability of space use and the impact of the environment on it need special test verification;

[0004] These problems limit the use of rope tension monitoring technology on spacecraft such as spacecraft, and even limit the use of related moving parts on spacecraft

With the development trend of lightweight spacecraft, the weight of each load on the spacecraft is required to be smaller and smaller. Therefore, the general force measurement technology uses a large weight and resources.
