Towards development of safety-enhanced leadscrew platform with floating mechanism

Abstract

The pursuit of precision and safety in vertical linear motion systems is of paramount importance in various industrial and automation applications. This thesis presents the design, analysis, and validation of a lead screw-operated vertical platform equipped with a floating nut and a safety nut. The primary objective of this research is to address the challenges associated with vertical linear motion mechanisms, including backlash, wear, and the need for enhanced safety measures. The platform's design integrates a novel floating nut mechanism that enables precise and controlled vertical motion while minimizing friction and backlash. Additionally, a safety nut is incorporated into the system to engage in emergency situations, providing an essential layer of protection against unforeseen mechanical failures in vertical applications. The research encompasses a comprehensive study of theoretical principles, design methodologies, and simulation techniques specific to vertical motion systems. Simulation and analysis are employed to evaluate the platform's performance under various loads, speeds, and vertical travel distances. Experimental validation tests are conducted to assess the practical applicability and reliability of the platform in vertical motion scenarios. The results demonstrate that the lead screw-operated vertical platform with a floating nut and safety nut offers superior precision, reduced backlash, enhanced safety, and efficient operation in vertical linear motion applications. This platform holds significant promise for industries requiring precise vertical positioning, such as elevators, material handling, and stage systems. By addressing the unique challenges of vertical linear motion, this thesis contributes to the advancement of automation and industrial processes, offering a potential solution for achieving unparalleled precision and safety in vertical motion systems. The findings presented here open new avenues for research and development, paving the way for innovative applications that demand reliable and precise vertical motion control. This research underscores the importance of tailored solutions in addressing the specific needs of vertical linear motion systems, with the potential to redefine the standards of precision and safety in vertical applications across various industries
