1 概况金属材料公司废钢料场的起重行车,主要用于废钢的装卸。在操作过程中,电磁盘的使用很频繁。电磁盘的电源是通过一条电缆专线提供的,而电缆线的伸缩是通过安装在小车上的一台电缆卷筒来完成的。该电缆卷筒是弹簧式卷筒,主要依靠弹簧力来伸缩电缆。由于使用频繁,弹簧有时有卡住现象,有时力量不一致。甚至有时产生断裂,使电缆线不能跟随起升的电磁盘同步运作;有时使电缆线被拉断而造成电源接
1 Overview Metal materials company crane yard lifting traffic, mainly for the loading and unloading of scrap. During operation, the use of magnetic disks is frequent. Power to the disk is provided through a single cable, which is retracted through a cable drum mounted on the trolley. The cable reel is a spring-loaded reel that relies mainly on spring force to retract the cable. Due to frequent use, sometimes the spring stuck phenomenon, and sometimes the power inconsistency. Sometimes even rupture, so that the cable can not follow the lifting of the synchronous operation of the disk; sometimes make the cable pulled off caused by the power connection
