摘 要:文章结合重大件物流搬运的特点,设计了一种面向中小修船领域的物流装备。该装备通过液压平板车潜入水下后将船舶夹紧托起,采用一体化控制技术,运用自动变量泵对平板的下潜、上移、升举、潜降、刹车进行控制,将船舶安全平稳地从水中移载到陆地进行维修改造或从陆地移运到水域,填补了国内10 000吨级以下船舶无需进船坞便可进行有效修理的市场空白。通过船厂应用,表明该物流装备能大大降低中小船厂承接修船业务的门槛,有效改善修船作业环境,缩短船舶维修和保养周期。

Abstract: This paper proposes a logistics equipment used in small and medium shipyards. The equipment is designed according to the characteristics of heavy-lifts material handling. In this system, a hydraulic pallet transporter can dive to be under a ship, clamp it and push it up. With integrated control technology, automatic variable pumps are used to control the diving, floating, lifting, depressing and braking of the transporter flatbeds. The ship can be moved from water to land safely and smoothly for repair or maintenance, or moved from land back to water. This system allows ships of under 10 000 tons to be repaired and maintained without docking. The system has been implemented in a shipyard. The case study demonstrates that the logistics equipment can help bring in new business opportunities in ship maintenance and repair for small and medium shipyards, effectively improve ship maintenance and repair environment, and reduce maintenance and repair cycle time.

随着我国装备制造、石化、冶金、能源等产业的快速发展,重大件物流需求日益增长[1]。目前,常用的重大件物流移运装备有辊轮小车、船台小车、气囊和自行式液压模块组合运输车(SPMT)等[2]。辊轮小车单车载重能力强,尺度小,在某些不宜布置过多移运设施的工程上是一种很好的选择;船台小车是一种传统的移运设施,功能相对完备,工厂对其操作熟悉,虽然受轨道限制,但在批量建造领域仍不失一种较好的选择;气囊虽然价格便宜,场地要求低,但由于其安全隐患以及不确定性多,一般仅限于在小型或临时性工程运用;SPMT功能完备,安全性、操作性均较好,且移动速度较快,组合灵活,载荷分配均匀,是较理想的移运设施,但价格高昂,限制了其大面积推广运用。

现有的重大件物流装备虽各具特色,并在一定范围和领域得到应用,然而在性价比方面都难以满足受当前激烈的市场竞争影响而急需转型的中小造船企业的需求。……
