摘要
以宁波轨道交通3号线一期工程的类矩形盾构机为依托,分析了类矩形管片拼装的难点。利用机构学知识,综合传统圆形拼装机构和该工程管片的特点,创新研发了一种1P5R串联型拼装机。结合对该拼装机机构形式和结构原理的介绍,探讨其特点及优势:体积小,动作灵活,可以实现90°以上的姿态调整;既能够完成类矩形圆周管片拼装,又能完成大长度中立柱的拼装。
Based on the rectangular shield machine for the first phase of Ningbo Rail Transit Line 3, the difficulties in assembling rectangular segments were analyzed. By using the knowledge of mechanism, traditional circular assembling mechanism and the characteristics of the segments, 1PSR, a tandem segment erector, was developed. The form and structural principle of the segment erector were introduced to discuss its characteristics and advantages： small volume, flexible movement, and is capable of making 90~of position adjustment. The segment erector applies to the assembly of both the rectangular-like pieces of circular tube and long columns.
