摘要随着现在世界的飞速发展，我国的绞车的性能为了能够跟上时代的步伐，在这次的毕业设计中我们想出了应用电液系统来让整个机器进行运转的方法使系统能够自行工作的设计。拖曳绞车也是一种重要地装备机械，它再海洋开发领域中有着广泛地应用。然而绞车地变节距排缆制约着现代绞车地发展。对其进行研究可以提高拖曳线列阵声呐地可靠性和实用性，具有重要地工程意义。

在这次设计中，在第一章我们对液压绞车的工作进行分析，和绞车类型分类和绞车如何进行工作进行分析。并且为了能够把整个绞车运行起来，我们进行了第二章的零件选型，并在零件选型基础上分析液压绞车的回路的工作原理和选型，并据此来画出了绞车的工作原理图。在第四章为了是装置再缆绳直径变化的情况下如何让绞车工作，我们设计了绞车的变节距下的控制设计。84904

Abstract  Towed line array is short for towed linear array sonar 。 Popular saying is that through a wire on a ship or submarine sonar, sonar was installed on a ship or submarine。 Clearly it is convenient, but the inherent noise of the ship itself can interfere with their work 。So there should be a towed array sonar and its biggest benefit is that sonar can get away from the noise, working better。 

In order to meet the needs of automation control , this paper presents an electro-hydraulic control of variable pitch towing winch。 Towing winch is also an important piece of equipment machine, which has a wide range of applications in the field of ocean development。 However variable pitch rows of cables restricts the development of modern winch。 To research can improve the reliability and practicality of towed linear array sonar , and has the significance of engineering 。 

In this design, the first chapter we analyze the work of hydraulic winch, winch and winch type classification and how to work for analysis。 And in order to be able to run the entire winch up, we conducted a second chapter of the component selection and analysis of hydraulic winch circuit works in component selection and selection basis and accordingly draw the winch works FIG。 In the fourth chapter to the case of varying diameter means longer cable winch how to work, we designed a winch control design of variable pitch under。In this design, the first chapter we analyze the work of hydraulic winch, winch and winch type classification and how to work for analysis。 And in order to be able to run the entire winch up, we conducted a second chapter of the component selection and analysis of hydraulic winch circuit works in component selection and selection basis and accordingly draw the winch works FIG。 In the fourth chapter to the case of varying diameter means longer cable winch how to work, we designed a winch control design of variable pitch under。
