大工作阻力液压支架柱帽柱窝损坏处理的研究

Study on Damage Treatment of Column Cap and Column Nest of Hydraulic Support with Large Working Resistance

以ZF13000放顶煤液压支架顶梁柱帽、底座柱窝发生损坏后的处理方案为例,对抗冲击柱帽、柱窝结构进行了修复设计,并介绍了各部位的功能和作用、处理过程中的相关关键件、立柱行程和外形,以及立柱固定方式方法。实践证明,该液压支架修复技术使用效果良好,值得借鉴。

The treatment scheme of ZF13000 caving coal hydraulic support roof cap and bottom pillar nest isken as an example. The design of the impact cylinder cap and the column structure is described, and the function d function of each part are introduced. Of the key parts, column mechanical travel and shape, as well as the col-n fixed method are also presented. Practice has proved that the use of hydraulic repairing technology is good, worthrning.
