Speed Detection of Rig Lifting System

Abstract:

Article Preview

Currently, speed detection of travelling block system is carried out mainly by detection roller speed, which results in a larger error. Against this background, a method to test crown block pulley was put forward, and its rotation speed precision and also its reliability were analyzed. The method is effective in improving detection accuracy and avoiding errors arising from skidding on the basis of applying the principle that rotation speed ratio of different fixed blocks is a constant value, thus judging the occurring of slipping by examining rotation speed for different fixed pulley. This method provides a guarantee for accurately controlling travelling blocks operational speed and height.
