8.8 m采煤机牵引箱加载试验设计与分析

Design and Analysis of Loading Test for Traction Box of 8.8 m Shearer

为了满足8.8 m厚煤层综采要求,对进口采煤机牵引箱进行了改造。根据改造后的牵引箱参数和结构,选择液压加载试验台进行加载,设计了牵引箱加载布置方案和加载控制方式。根据试验标准和目的,通过对试验结果的分析,牵引箱符合出厂试验要求。

In order to meet the requirements of fully mechanized mining on 8.8 m thick coal seam, the traction box of imported shearer was modified. According to the parameters and structure of the traction box, the hydraulic loading test bench was selected,and the loading arrangement and loading control method were designed. Based on the test standard and purpose,the test results was analyzed,the factory test requirements of the traction box was met.
