摘　　要：为了满足9 m采高特厚煤层综采要求,设计了MG1100/3050-WD采煤机。鉴于新牵引箱的结构和参数,选择了倒置的加载方式。采用液压加载试验台进行热平衡试验,并对试验结果进行了分析,满足空载试验和热平衡试验标准和要求。此牵引箱达到型式试验要求,可以出厂进行工业性试验。In order to meet the requirements of fully mechanized mining of 9 m mining height thick seam,the MG1100/3050-WD shearer was designed. In view of the structure and parameters of the new traction box,an inverted loading method was chosen. The heat balance test was carried out using a hydraulic loading test rig and the test results were analyzed. After the no-load test and heat balance test,the traction box meets the type test requirements,and it can be used for industrial test.
