[0002] In engineering practice, the double-wheel mill mainly implements the excavation work through the winch, and the winch can lift or lower the frame of the double-wheel mill through the steel wire rope and the pulley block.

[0003] However, as the background art in the patent document with the announcement number CN206245367U states, in actual work, the winch needs to provide a certain lifting force to the double-wheel mill to enable it to cut. Therefore, for the winch that pulls the double-wheel mill through the steel cable, as long as the double-wheel mill is working, the winch is working all the time; such a great loss to the winch.

[0004] Although CN206245367U proposes a solution to the above problem, however, in CN206245367U, the micro-feeding device is arranged at the top of the mast and integrated with the overhead traveling crane, in practice, such a structure increases the weight at the top of the mast, which easily leads to the instability of the center of gravity of the whole machine, and such a design also makes the structure of the overhead traveling crane complicated, which needs frequent maintenance, and the high-standing mast also makes the operator need to work in high altitude, which has many unsafe factors.
