【摘要】：随着近年来我国集装箱港口运输领域的迅猛发展，桥吊的起升高度和运行速度逐步提高，，一味沿袭以往在吊具上架上安装电缆储缆筐的方式已很难适用。实践证明，该方式只适用于起升高度不高于30米的岸桥且在风力较小的工作环境下工作。如果起升高度和速度高出某个值时，吊具电缆就会发生反转及出筐的情况，极大的妨碍岸桥的正常使用。因此在岸桥上用吊具电缆动力卷缆装置来替代电缆储缆筐势在必行。从十多年前起，各相关公司便开始研发岸桥吊具电缆张紧系统。设计师们开始在小车架上安装一套可与起升机构同步运行的吊具电缆收放系统，使吊具电缆始终能够灵巧而精准地跟随吊具的运动，消除气候环境的影响的同时，减少了吊具电缆故障的发生。本文将从市场上吊具卷缆系统发展入手，对市场上常用的几种吊具电缆控制方式详细的介绍。并相互比较找出各自的优缺点及适用场合等。根据各现场使用情况进行总结及用户对于吊具电缆系统使用情况的反馈意见进行分析，提出改进措施及程序优化。然后从工程项目着手，根据项目要求制作计算书，设计程序及设定参数等，实现磁滞式电缆卷盘控制功能。现场使用表明，达到了预期的设计目标。
[Abstract]:With the rapid development of container port transportation in our country in recent years, the lifting height and running speed of the bridge crane have been raised gradually. It is difficult to apply the way of installing cable storage basket on the crane shelf blindly, which has been proved by practice. This method is only suitable for shore bridges with lifting height of not more than 30 meters and working in a less windy working environment. If the lifting height and speed are higher than a certain value, the hoisting cable will reverse and exit the baskets. This greatly hinders the normal use of the quayside bridge, so it is imperative to replace the cable basket with the cable hoisting device on the shore bridge. Since more than a decade ago, companies have been developing cable tension systems for quayside hangers. Designers have started installing a cable retracement system that can run synchronously with the lifting mechanism on a small car frame. The cable of the hanger can follow the movement of the hanger dexterously and accurately, eliminate the influence of the climate and environment, and reduce the fault of the cable of the hanger at the same time. In this paper, we will start with the development of the hoisting system in the market. This paper introduces in detail several kinds of cable control methods commonly used in the market, and compares with each other to find out their own advantages and disadvantages and the applicable situations. According to the situation of each field use, the author summarizes the usage of the cable system of the hanger and the user's situation about the use of the cable system of the hanger. The feedback of the situation is analyzed, The improvement measures and program optimization are put forward. Then according to the requirements of the project, the calculation book, the design program and the setting parameters are made to realize the control function of the magnetic hysteresis cable reel. The field application shows that the expected design goal has been achieved.
