The design of the hydraulic anchor
Abstract: This design for Marine hydraulic control valves to improve the anchor design, by using the quantitative pump-two-way hydraulic motor loop, manual directional control valve, double relief valve safety protection, simple structure, reliable oil. Can be generalized to other inland ship sailed and and mooring homework equipment. Through to the quantitative pump-two-way hydraulic motor loop of the research and the basic principle of the formula deduction, verify the quantitative pump-two-way hydraulic motor loop connection of advantage, determine the research direction, and then by the hydraulic and pneumatic transmission ", "the mechanical design", "the mechanical theory", "modern machine design method" and other relevant basic books the study and research, after a great deal of research putation, design bination of the basic shape and size control valve, and finally through the related technical books and guide teacher patience guidance, to determine the design of the shape, size and processing technology. And through the CAD software engineering chart drawing and modification.

1 引言
近年来由于近岸工程的迅速发展,为了满足河内开发和近岸工程的发展的需要,在一般的小吨位内河船上,开始采用液压或者电动的起锚绞车来进行起锚、抛锚和泊系作业,来提高作业效率和降低船舶操作人员的劳动强度。内河船用起锚绞车具有起锚和泊系作业能力,一机两用,节省设备,增大船舶的使用空间。由于以往在小吨位的船舶上配置的大多是手动的起锚绞车,他们面临着被更新换代的趋势,因此液压起锚绞车在内河船上具有较大的市场潜力。本文就笔者所研发的内河船用起锚绞车进行简单的介绍。
