Research on Spinning Lock Load Weighing System

为解决岸边集装箱起重机传统测量方法响应慢、精度差、可靠性低、易损坏的问题,提出一种基于旋锁称重的集装箱起重机载荷监测系统。旋锁载荷称重系统由测力单元、数据处理器及系统内通信总线、司机室报警显示单元、系统对外通信总线和数据存储单元组成,用于监测集装箱起重机吊具的起吊质量,将测力单元的传感器集成在集装箱起重机的旋锁内。该系统具有响应快、精度高、可靠性高、不易损坏等优点,同时可以实时监测、显示吊具每个旋锁上的载荷,并将质量数据存储起来。在监测到旋锁载荷异常时,系统可以迅速进行声光报警,或直接锁定吊具驱动电机,阻止非正常起吊,预防事故发生,提升集装箱起重机的安全性。此外,采用旋锁载荷称重系统可以保障提升机构的钢丝绳不会因过重而出现变形和损坏,进一步提升岸边集装箱起重机的安全性。

In order to solve the problems of slow response,poor accuracy,low reliability and easy damage of the traditional measurement method of container crane on shore,a load monitoring system of container crane based on spunlock weighing was adopted.The spinner load weighing system is composed of force measuring unit,data processor and communication bus in the system,alarm display unit in the driver’s cab,external communication bus of the system and data storage unit,which is used to measure and monitor the lifting quality of the lifting gear of the container crane.The sensor of the force measuring unit is integrated in the spinner of the container crane.The system has the advantages of fast response,high precision,strong reliability,easy damage,and so on.At the same time,it can monitor and display the load on each spreader’s spinner in real time,and store the quality data.When the abnormal spinner load is detected,the system can quickly make sound and light alarm,or directly lock the spreader drive motor to prevent abnormal lifting,prevent accidents,and improve the safety of container cranes.In addition,the use of spinlock load weighing system can ensure that the rope of the lifting mechanism will not be deformed and damaged due to excessive weight,and further improve the safety of the container crane on the shore.
