摘要
U型板桩因异型截面重心偏移,传统索具多点受力不均,导致吊装对位慢、机械介入率低、破损与倾覆风险高。为破解上述瓶颈,亟需开发高效、安全、低损的专用吊具。本研究旨在设计一种新型专用吊具以提升其吊装效率和安全性。综合运用观察法、文献分析法和案例研究法,对U型板桩的现有吊装过程进行了深入分析与研究。研究结果表明:该新型吊具拆卸方便,有效减少了50%调整桩位的时间,提升了U型板桩吊装效率。此外,吊具中集成的橡胶垫能够有效缓冲冲击,板桩破损率减少了66.5%,并通过传感器实时监控垂直度,可实现及时调整纠偏,提高吊装精准度14.33%。本研究设计的新型专用吊具及其配套装置,显著提高了U型板桩吊装的机械化程度、精准度和安全性,有效解决了传统吊装过程中的痛点,具有良好的应用前景和推广价值。
Due to the off-center gravity of the U-shaped sheet pile's irregular cross-section,traditional lifting gear results in uneven force distribution across multiple points,leading to slow positioning,low mechanical intervention rates,and high risks of damage and overturning.To address these bottlenecks,there is an urgent need to develop specialized lifting equipment that is efficient,safe,and minimizes damage.This study aims to design a new specialized lifting tool to enhance its efficiency and safety in handling U-shaped sheet piles.By comprehensively employing observation methods,literature analysis,and case studies,the existing lifting process of Ushaped sheet piles was thoroughly analyzed and researched.The findings indicate that the new lifting tool features easy disassembly,effectively reducing pile alignment adjustment time by 50% and improving the lifting efficiency of U-shaped sheet piles.Additionally,the integrated rubber pads in the tool provide effective shock absorption,reducing pile damage by 66.5%.Real-time verticality monitoring via sensors enables timely adjustments and corrections,improving lifting precision by 14.33%.The newly designed specialized lifting tool and its supporting devices significantly enhance the mechanization level,precision,and safety of Ushaped sheet pile lifting,effectively resolving pain points in traditional lifting processes.This research demonstrates strong application potential and value for widespread adoption.
