1.概述 我国常用的高炉料车卷扬系统一般只设卷扬电动机的加减速装置,没有缓冲装置,如果在上料卷扬系统中增设缓冲装置,将会延长卷扬系统设备的使用寿命,大大减少设备事故的发生。 简易的缓冲装置可在料车与提升钢绳之间加一短弹簧(见图1),降低系统的刚度,起到缓冲减振作用。 2.上料卷扬系统的缓冲分析 我厂2号炉上料卷扬系统技术参数如下: 料车自重:W=1128kg; 1. Overview In our country, commonly used blast furnace hoist winch system generally only winch motor acceleration device, there is no buffer device, if the feeding hoist system to add a buffer device, will extend the hoist system equipment life, Greatly reduce the occurrence of equipment accidents. Simple buffering device in the hopper and hoisting steel rope plus a short spring (see Figure 1), reducing the stiffness of the system, play a damping effect. 2 feeding hoist system buffer analysis I plant 2 furnace hoisting system technical parameters are as follows: Hopper weight: W = 1128kg;
