A guiding rope tension measuring device

Abstract

The invention provides a guide rope tension measuring device, relates to the field of mechanical measurement and aims at solving the problem that the existing measuring device cannot accurately measure coring force and smoothly guide the coring force to a sample under complex selenographic environments and the multi-force composite effect. The guide rope tension measuring device provided by the invention comprises a base, a rotating shaft, a rotating block, a pressure sensor, pretightening springs, pretightening screws, a guide sleeve, a guide shaft and a guide rope through hole, wherein the base and a side end of the rotating block are fit with each other through the rotating shaft, an upper end surface of the rotating block is fixed at an upper part of the base through two pretightening screws, the pretightening springs are arranged on the pretightening screws. The guide rope tension measuring device is used for the mechanical measurement of the guide rope.

Description

technical field [0001] The present invention relates to the field of mechanical measurement, in particular to a guiding rope tension measuring device. Background technique [0002] Aerospace is a frontier project for human beings to explore the natural world. Going into space has become an indispensable symbol of a scientific and technological power. The lunar exploration project is a relay stage of my country's aerospace industry. The results will provide valuable experience for the next step of outer space exploration. Lunar exploration mainly uses remote sensing and final moon landing to uncover the mystery of the lunar environment. After landing on the moon, a series of scientific research projects will be carried out on the moon. Links are very important. One of them is to obtain samples of lunar manifestations, which involves the measurement and control of coring force and the orientation of samples during the sampling process. How to accurately measure the coring forc...

Problems solved by technology

[0003] In order to solve the problem that the existing measuring device cannot accurately measure the coring force and guide smoothly under the complex environment of the lunar surface and the multi-force compound action, and the long-line device of the dynamometer in the prior art cannot carry out lunar exploration sample sampling under the multi-force compound action Accurate measurement of coring force, and the long rope device of the dynamometer in the prior art does not have the function of changing the angle of the rope and guiding the force during force measurement, and the force measuring device is easily affected by the vibration and impact generated when the aircraft rises and falls. When the pressure sensor is damaged, it is difficult to ensure that the measurement accuracy of the sensor is not affected, and then a guiding rope tension measuring device is provided.
