带式输送机张紧布置的优劣对比及选择

Comparison and selection of belt conveyor's tensioning arrangement

张紧装置在带式输送机中起着满足起动、运行不打滑以及限制输送带下垂度的作用,选用应遵循“合力最小化、结构最简单、行程易控制”的原则,配置朝着免维护的方向选取,本文对3种类型带式输送机中张紧位置的不同分别作了张紧力的计算推导,系统阐述了不同类型带式输送机的张紧应该设置在什么位置更为合理,对带式输送机张紧布置的优劣举例进行了说明,并列出了配置选取表,供同行业作技术参考。

The tensioning device plays a role in satisfying the starting and running of the belt conveyor without slipping and limiting the droop of the conveyor belt.The design should follow the principle of"minimum force,simplest structure and easy control of travel",and the configuration should be selected in the direction of maintenance-free.This paper calculates and deduces the tensioning force for the different tensioning positions of three types of belt conveyors.This paper systematically expounds where the tensioning position of different types of belt conveyors should be set in a more reasonable way,illustrates the advantages and disadvantages of the tensioning arrangement of belt conveyors with examples,and lists the configuration selection table for the industry as a technical reference.
