| Integrated mining system consists of the electro-hydraulic controlled hydraulic support, the high-power and wide-surface scrapper, the highly integrated coal cutter, the self-shift belt conveyor, the trains for moving transformer and oil water emulsion pump stations, is a kind of high yield and efficiency mechanized mining system,which is blend of supporting, loading of coal, transporting of coal, and self-shift device. In the high- yield and efficiency mining system, the monorail crane working in the fully mechanized mining face undertake the task that it suspend all the dynamical cable, emulsion pipe and water pipe for dust fall.However,the transportation of the cable and pipes is inconvenient because of their own characteristic and working environment. The cable and pipes are so easily damaged which will lead to shutdown, stop production even grave security incident. In order to ensure safety in production, improve production efficiency, the need for a new delivery method is pressing. Therefore, the research on transport device for the mining cable and liquid pipes have important guiding significance on actual production.This subject regards the cable dolly driving device as the research object. At first, using the digitized product design software UG (Unigraphics NX),sets up the solid modeling of the machinery part which is channeled into ADAMS environment with Parasolid-file format and sets up Virtual Prototype of a machine model. Then the hydraulic system of the driving system was systematically analyzed and designed: the total structure and principle of transmission were studied, then the system principle diagram was set down and the calculation and choices for the components of the hydraulic system were done according to the request of the machine structure and environments to system. Finally, do the mechanical systems and hydraulic systems united simulation.
