21型强力带式输送机是年产量在百万吨以上的大、中型煤矿主要的运输设备之一,在整个煤矿生产中发挥着巨大作用。上托辊支架是带式输送机主要的部件,数量大。在一标准运距为1500m的强力带式输送机中,上托辊支架就有1250组。我们应用VE,对上托辊支架进行了价值分析,并对其零件之一——侧支板进行了改进。 1 上托辊支架的价值分析 上托辊支架(图1)是由侧支板、肋板、支座、角钢4个零 Belt Conveyor 21 is one of the major transport equipment for large and medium-sized mines with an annual output of over 1 million tons and plays a significant role in the entire coal mine production. The upper roller bracket is the main part of the belt conveyor, a large number. In a standard belt conveyor 1500m strong belt conveyor, the upper roller bracket has 1250 groups. Using VE, we conducted a value analysis of the upper roller support and improved one of its parts, the side supports. 1 on the value of the roller bracket on the roller bracket (Figure 1) is by the side support, ribs, bearings, angle 4 zero
