摘要船舶工业是为水上交通、海洋开发及国防建设提供技术装备的现代综合性产业,是军民结合的战略性产业,是先进装备制造业的重要组成部分。进一步发展壮大船舶工业,是提升我国综合国力的必然要求,对维护国家海洋权益、加快海洋开发、保障战略运输安全、促进国民经济持续增长、增加劳动力就业具有重要意义。43848 同时,必须清醒地看到,我国船舶工业在高速发展中也积累了不少矛盾和问题,主要表现在:创新能力不强,结构性矛盾突出,产业集中度较低,生产效率和管理水平亟待提高,船舶配套业发展滞后,海洋工程装备发展步伐缓慢。与世界造船强国相比,我国船舶工业整体水平和实力仍有较大差距。 起锚机是船舶配套设施中的一个重要组成部分。船舶驶达港口,常常因为等候泊位,接受检疫或避风等需要在港口外停泊,为了能克服停泊时作用在船体上的水流力、风力和船舶倾斜时所产生的惯性力,就需要在船上设置锚设备,以保持船位不变。此外,锚设备还可帮助安全离靠码头,或使船舶紧急制动。 目前国内在起锚机方面研究相对落后,本次课题亟待解决液压起锚机的设计问题。液压起锚机相对于其他锚机,具有明显的优势,其操作灵活,调节方便成为其显著特点。本次研究的液压起锚机采用离合器控制锚链轮同时转动,而由液压泵来控制离合器的分合,运用十分方便。本设计结合以往起锚机的结构,增加了液压泵控制离合器的部分,使液压起锚机更加实现了自动化。根据结构,绘制了液压起锚机的CAD图,以及通过三维软件绘制了液压起锚机的三维造型。 毕业论文关键字:船舶,起锚机,液压,设计校核,三维建模 Abstract Shipbuilding industry is for water traffic, Marine development and national defense construction to provide the comprehensive technical equipment of modern industry, with the civilian is the strategic industry, of advanced equipment manufacturing is the important part. Further development and growth of shipping industry, is to promote the inevitable requirement of China's overall strength, the maintenance national maritime rights and interests, and speed up the ocean development, security strategy to promote national transportation safety, economic growth, and to increase the labor employment to have the important meaning. At the same time, we must be clearly aware that China's shipbuilding industry in the developing has accumulated a lot of contradictions and problems, mainly displays in: innovation ability is not strong, structural contradiction between, industrial concentration is low, the production efficiency and management level to improve, ship supporting industry development lags behind, the slow pace of Marine engineering equipment development. Compared with the world shipbuilding power, China's shipbuilding industry overall level and strength is still a great distance. Anchor machine is supporting facilities of the ship is an important part. Ships sail to port, often because wait for garage, accept and quarantine or shelter in port need to be anchored outside, in order to overcome the anchor role when the flow of water in the hull strength, and wind and ship tilt generated when the inertia force of, you need in the ship set anchor equipment, in order to maintain the same position. In addition, the anchor equipment but also help from security by terminals, or to make the ship emergency braking. The current domestic anchor and research in machine is relatively backward, this topic to be solved anchor the design of hydraulic machine. Anchor and hydraulic machine relative to other anchor machine, has many obvious advantages, its operation is flexible and convenient adjustment as its notable features. The study of hydraulic machine adopts anchor and the control chain wheel also rotating, and to control the hydraulic pump by clutch points close, use very convenient. This design is introduced the anchor and hydraulic machine development direction, and the main parts design checking and 3 d modeling。 (责任编辑:qin) |
