【摘要】：航标船在航标投放作业中,关键是航标锚链上船后的处理工作。原立式绞盘在锚链收绞过程中,极易造成锚链之间的挤压乱缠,需要人工撬杠配合才能使锚链完成绞收工作；锚链释放过程中，仍需人工配合，才能使锚链顺利从立式绞盘上分离开来；这种作业方式中工人劳动强度较大，操作危险性较高，作业人员安全得不到保证；对船舶自身作业人员数量需求较多，不利于船舶实现自动化。本论文提出液压油缸排链绞车的设计思路：该新型绞车采用卧式卷筒、液压油缸排链机构，安装在船舶甲板轴线的适当位置上，其主体卷筒的旋转功能由液压马达驱动减速机、带动一开式齿轮副运行完成；同时排链液压油缸推动一摆臂结构在一定角度范围内往复运动，带动其上的转盘引导锚链整齐缠绕在卷筒上或均匀地从卷筒上释放出来，实现自动排链，使得生产效率大大提高。本文围绕液压油缸排链绞车的设计，主要进行了以下工作： 1.通过对船舶功用的分析，，确定了200KN油缸排链液压绞车的总体布局。 2.在机械结构的设计中，通过详细的分析计算确认了卷筒组件、棘轮机构、排链机构型式；建立绞车机体结构的模型，并采用有限元分析软件对模型进行了仿真校核。 3.按照液压绞车的传动路线，对液压马达、减速机、齿轮副大小齿轮、主轴的参数进行了设计。 4.在液压系统设计中通过对液压马达、液压油缸的选型，推算出动力源部分电机和柱塞泵的选型，并对系统的液压回路进行了设计。 5.控制系统是最终实现液压油缸排链与卷筒旋转同步的保证。通过齿轮齿数的准确的计测和排链油缸的位移的控制，通过PLC程序进行动态控制，达到最终的同步要求。
[Abstract]:The key is the handling of the Anchorage chain during the operation. The original vertical winch is easy to cause the compression and tangling between the anchor chains in the course of the chain winding, so it needs the coordination of the manual crowbar to make the chain complete the winch work, and in the course of the chain release, it still needs the manual cooperation. In order to separate the anchor chain smoothly from the vertical winch, the workers in this work mode have higher labor intensity, higher operational risk, and the safety of the operators can not be guaranteed; there is more demand for the number of the ship's own operators. It is not conducive to the automation of ships. In this paper, the design idea of hydraulic oil cylinder chain winch is put forward: the new type winch adopts horizontal reel, hydraulic cylinder chain mechanism, installed on the proper position of ship deck axis, and the rotation function of the main reel is driven by hydraulic motor. At the same time, the hydraulic cylinder of the chain pushes the swinging arm structure to move back and forth within a certain range of angles, driving the turntable on it to guide the anchor chain to be neatly wound around the reel or released from the reel uniformly. The automatic chain arrangement is realized, and the production efficiency is greatly improved. This paper focuses on the design of hydraulic cylinder chain winch, mainly carried out the following work: 1. By analyzing the function of the ship, the overall layout of the 200KN hydraulic winch is determined. 2. In the design of mechanical structure, the types of reel assembly, ratchet mechanism and chain arrangement mechanism are confirmed through detailed analysis and calculation, and the model of winch body structure is established, and the model is simulated and checked by finite element analysis software. 3. According to the transmission route of hydraulic winch, the parameters of hydraulic motor, reducer, gear pair size gear and spindle are designed. 4. Through the selection of hydraulic motor and hydraulic cylinder in the design of hydraulic system, the selection of motor and piston pump of power source is calculated, and the hydraulic circuit of the system is designed. 5. The control system is the guarantee to realize the synchronous rotation of hydraulic cylinder chain and reel. Through the accurate measurement of gear tooth number and the control of displacement of chain oil cylinder, the dynamic control is carried out by PLC program, and the final synchronous requirement is achieved.
