Optimization of Hoisting Attitude in Non-standard Steel Structures via Adjustable Counterweight Balance Beam Technology
Journal Title: Journal of Civil and Hydraulic Engineering - Year 2023, Vol 1, Issue 1
Abstract
In addressing the challenge of precise lateral attitude adjustment during high-altitude hoisting of non-standard steel structures, such as the rotating platforms in rocket launch towers, a novel approach involving an adjustable counterweight balance beam has been developed. This method entails the strategic placement of movable counterweight blocks on the balance beam, thereby enabling the manipulation of the gravity center's distribution for refined posture control of the load suspended beneath the beam. A theoretical model encompassing static balance and deformation coordination has been formulated for this adjustable balance beam system. Utilizing Matlab for computational analysis, the model elucidates the effects of various parameters, including the counterweight block position, block weight, lifted load, sling length, and balance beam length on the beam's attitude. The findings suggest that the beam's performance can be optimized in accordance with the weight of the load. Through the judicious design of the sling and beam lengths, as well as the counterweight block mass, continuous fine-tuning of the hoisting posture is achievable via progressive adjustments of the counterweight block's position on the balance beam. The theoretical calculations and analyses derived from this study offer valuable insights for the design of new balance beams and the enhancement of hoisting operations, catering to the specific demands of high-precision, high-altitude lifting tasks.
