The invention relates to the field of a crawler walking mechanism, and particularly to a walking mechanism of a fully-mechanized coal winning machine. The walking mechanism of the fully-mechanized coal winning machine comprises a crawler frame, a driving wheel, a guiding wheel and a crawler plate. The walking mechanism of the fully-mechanized coal winning machine furthermore comprises a bearing rack which is arranged below the crawler frame between the driving wheel and the guiding wheel and is made of wearing-resistant steel plate, and positioning blocks which are respectively welded in front of and behind the top of the bearing rack. The lower part of the crawler frame is provided with positioning troughs which are in snapped cooperation with the front positioning block and the back positioning block. Compared with the prior art, the walking mechanism of the fully-mechanized coal winning machine has advantages of low fabrication cost, simple and convenient mounting, and simple maintenance. A good effect of no accident in ten-kilometer winning distance is realized in an actual use process, thereby reducing a resistance in walking of the fully-mechanized coal winning machine, reducing labor intensity of maintenance personnel, prolonging use time of the walking mechanism of the fully-mechanized coal winning machine, and saving comprehensive cost. Regular conveying of the walking mechanism of the fully-mechanized coal winning machine to a wellhead for maintenance is replaced by daily inspection, thereby reducing time in detachment, conveying and mounting of the equipment. The walking mechanism is suitable for various types of fully-mechanized coal winning machines.
