The stage loader self movement system is composed of the moving cylinder, supporting cylinder, quide rail and connectingparts, etc. lt is used for the fast moving of the high production and efficient working face channel transfer machine and thecrusher, which can meet the needs of the high progress and fast advancing of the working face.The device breaks through thetraditional hvdraulic cvlinder anchorina and pulina mode, and its principle is that the transfer machine, crusher and the movincdevice use the friction force to sunport each other, push and pull each other, so as to realize the function of moving fonward ovthemselves.The self-moving system and the belt conveyor tal are used together, which can adapt to the overall self-moving ofthe channeling equipment.The device is suitable for the operation mode of twotool one-shift or three-tool one-shift. With thehigh-pressure emulsion as the hydraulic power, the outlet pressure of theis 31.5mpa, and the working pressure ofpumo stationthe hydraulic system is 20MPa. Compared with the traditional transfer machine, the devicehas the advantages of high progressfast advance, simple operation and convenience.The raised cvlinder adopts floatina desianto avoid cvlinder deformation andseal failure.
