The invention discloses a method for laying a large-diameter maritime work anchor chain through a tensioner, and relates to the technical field of ocean engineering anchor chain laying construction.The method comprises the following steps that the large-diameter maritime work anchor chain is integrally hoisted to the surface of a deck of a laying ship from a transport ship, and an anchor chain ring is clamped through a first pawl wheel and a second pawl wheel; meanwhile, the anchor chain ring is placed in the chain guide groove; in the laying process, the clamping force of the tensioner and the driving force of the pawl wheel are set according to the tension required by the line type of the catenary of the anchor chain in water; when the whole anchor chain is laid to the tail end, the tensioner and the crane are adopted to assist in construction, and after the crane hangs a sling, a tensioner telescopic oil cylinder acts at the same time to enable the movable box body to move upwards. The construction method for laying the whole large-diameter maritime work anchor chain is achieved, the design form of the pawl wheel and the adjustable chain guide groove can meet the requirement for laying maritime work anchor chains of different specifications and sizes within a certain range, the untwisting procedure before anchor chain laying is optimized, the construction efficiency can be improved, and the construction cost is reduced.
本发明公开了一种采用张紧器铺设大直径海工锚链方法,涉及海洋工程锚链铺设施工技术领域,包括以下步骤:将大直径海工锚链从运输船上整体吊到铺设船甲板表面,利用第一棘爪轮和第二棘爪轮夹持住锚链环,同时将锚链环放入导链槽内;在铺设过程中根据锚链在水中的悬链线线型所需张力设定张紧器的夹持力和棘爪轮的驱动力;当整体锚链铺设至末端时,此时采用张紧器和吊机辅助施工,吊机挂设好吊索具后,张紧器伸缩油缸同时动作使移动箱体上移。本发明实现了大直径海工锚链整条铺设的施工方法,棘爪轮和可调节式导链槽的设计形式可以满足铺设一定范围内不同规格尺寸的海工锚链,优化掉锚链铺设前的解扭工序,可提高施工效率,降低施工成本。
