移设机是斗轮挖掘机主要配套设备之一,其夹轨器支撑的设计往往不被重视。这种结构重量大,抗弯能力差,使用过程中常常发生弯曲变形,以致移设机不能正常工作. 夹轨器支撑采用薄壁箱形结构最为合理。重量轻、抗弯抗扭性能都较好。一、夹轨器支撑受力状况移设机正常运行过程中,夹轨器在水平面内承受一个横向拉力F_2+W和纵向牵引阻力F_1+W_1。由图1可知,夹轨器支撑的两端分别用铰链连接,一端连在夹轨器上,另一端连接到机
Moving machine is bucket wheel excavator one of the main ancillary equipment, its rail clamp support design often not be taken seriously. This kind of structure has the advantages of big weight and poor bending resistance, and often causes bending deformation during use, so that the moving machine can not work normally. It is most reasonable to adopt the thin-walled box-shaped structure for the rail clamp support. Light weight, bending and torsional performance are better. First, the rail clamp support force conditions Moving machine during normal operation, rail clamp in the horizontal plane to withstand a horizontal pull F_2 + W and vertical traction resistance F_1 + W_1. As can be seen from FIG. 1, both ends of the clamp rail support are respectively connected by hinges, one end of the rail clamp is connected with the clamp rail, and the other end of the clamp rail is connected with the machine
