It breaks through the traditional transportation method of roadheaders and realizes functions such as automatic movement, automatic deviation adjustment, and continuous transportation.

[0003] When the tail of the self-propelled walking machine moves, the height adjustment cylinder rises, so that the tail of the self-propelled walking machine is lifted as a whole, the guide rail serves as a support, the piston rod of the shifting cylinder extends, and the tail of the self-propelled walking machine moves forward a stroke as a whole; the height adjustment cylinder drops, so that the tail of the self-propelled walking machine is lowered as a whole, the frame contacts the roadway ground as a support, the piston of the shifting cylinder retracts, and the guide rail moves forward a stroke; the above steps are repeated to realize the movement of the tail of the self-propelled walking machine. During use, when the roadway ground is uneven, the tail of the self-propelled walking machine is prone to tilt, affecting production. Therefore, it is necessary to develop a support surface detection alarm device for the tail base to detect the flatness of the roadway ground.
