皮带输送机的常规设计方法所存在的问题带式输送机常规设计方法实际上是一种安全或是偏于保守的设计方法。例如。选用的输送带安全系数、运行阻力系数偏大，从而造成选用的电动机功率过大，辊道价格，带宽过宽或是抗拉强度要求较高。
The conventional design method of belt conveyor is a safe or c***ervative design method. For example. The safety factor and the running resistance coefficient of the selected conveyor belt are too large， resulting in excessive power selection， wide bandwidth or high tensile strength.
用这种支架时，辊子安装完毕需用钢丝进行锁紧（即相邻3～5个辊子轴用钢丝串在一起）。辊子Φ155的支架采用槽钢，辊子轴用压板和螺栓固定在槽钢翼缘上。
When the bracket is used， the roller is installed with the steel wire to be locked (that is，辊道厂家， the 3~5 roller shafts are strung together with steel wire). The support of the roller 155 is used in the channel steel， and the roller shaft is fixed on the flange of the channel steel with the press plate and bolt.
支柱一般采用型钢焊接而成，上部用螺栓与支架连接，辊道，下部用地脚螺栓与地坪固定。按用途支柱可分为对接支柱和中间支柱，两标准段支架之间采用对接支柱支承，辊道哪家好，其余（包括端部）则采用中间支柱支承。支柱的设计一般按受压柱的稳定性来控制。
The pillar is usually welded by the steel type steel， the upper part is connected with the bolt and the support， and the bottom is fixed with the ground bolt and the the use pillar， it can be divided into the docking pillar and the middle pillar. The two bracket is supported by the docking pillar， while the rest (including the ends) is supported by the intermediate support. The design of the pillar is generally by the stability of the compression column.
