Tension analysis of the drum shearer hydraulic pull rod
摘要
Abstract
To study the effect of the shearer drum cutting load to the four hydraulic pull rods,the force model of the four hydraulic pull rods was established under the shearer working load by u-sing the small displacement deformation coordination principal and the statics equilibrium equa-tion,and the load formula was derived.Assuming the pre-tension load of four pull rods was 500 kN,the force model of the pull rod w as solved by input the test loading of the drum and the sliding shoes.The test results showed that the deformation average of four pull rods were 3.164 2,1.934 8,2.353 8,2.248 8 mm respectively.The loads of the four pull rods were different in the w orking process of the shearer,w here the largest load of pull rods w as on the upper coal wall,the average value was 536 578 N,the lowest load of pull rods was on the goaf,and the av-erage value was 449 991 N.The accuracy of the pull rod force model was verified by the test.The research results provide the convenience to the setting of the pre-tension force of the shearer hy-draulic pull rod and the lifetime analysis.关键词
