摘要： 本文首先从现有单桩抱桩装备的抱桩系统中存在的问题出发，通过第一代步进式伸缩梁系统的设计，成功解决了推力油缸行程小的问题；其次，通过第二代步进式伸缩梁系统的设计，简化了第一代系统的构成，同时解决了推力油缸直接接触单桩的问题，从根本上解决了油缸可能损坏的问题，大大提升了系统可靠性；最后，将步进式伸缩梁系统成功应用在实际工程中，进一步验证了设计的可靠性。

Abstract: In this paper, starting from the existing problems in the pile holding system of monopile holding equipment, the small stroke problem of the thrust cylinder is successfully solved through the design of the first generation step-by-step retractable beam system. Through the design of the second generation step-by-step retractable beam system, the composition of the first generation system is simplified, and the problem of thrust cylinder direct contact with the monopile is solved, which fundamentally solves the problem of possible damage of the thrust cylinder, and greatly improves the reliability of the system. Finally, the successful application of the step-by-step retractable beam system in practical engineering further verifies the reliability of the design.

Key words: step-by-step, retractable beam system, monopile, pile holding system, WTG foundation, thrust cylinder
