大型上运带式输送机逆止器选型探讨

摘要

介绍了逆止器在矿用带式输送机选型过程中的重要性，为准确进行逆止器选型计算，列举了逆止力矩常用的4种计算方法，结合设计实例对4种方法进行对比，分析其各自优缺点，确定了合理计算方法；通过逆止工况下带式输送机输送带瞬时张力计算，推导出逆止打滑验算校验公式，并提出解决打滑问题的具体方法；最后总结了逆止器常用布置方式及其特点。%The paper introduced the importance of backstop in selection for mine belt conveyor. To realize the accurate calculation for type selection,four commonly⁃used calculation methods of backstop torque were introduced in this paper,these methods were compared and analysed,and reasonable calculation method was determined through analyzing their respective advantages and disadvantages. By calculating the instantaneous tension of belts on belt conveyor under non⁃return condition,the skid checking formula was summed up, the method of solving the problem of sliding was also put forward.Finally,commonly⁃used arrangement mode and characteristics of the backstop device were summarized .
