A kind of cable wire winding method of headstock gear, the cable wire is through left around to the second movable pulley under the left-handed portion's cable trough of reel
Hereafter grooving is moved by the right grooving of the first fixed pulley, the right grooving of the first movable pulley, the left grooving of the first fixed pulley, first successively
The left grooving of pulley, equalizer pulley, the right grooving of third movable pulley, the right grooving of the second fixed pulley, the left grooving of third movable pulley, second are determined
The left grooving of pulley, the right grooving of the second movable pulley, finally on around in through reel dextrorotation portion cable trough.
Compared with prior art, the beneficial effects of the utility model are：
1st, existing single-unit reel is divided into two sections, the respectively left-handed portion of left hand direction and the dextrorotation portion of clockwise direction, and
By the way that corresponding running block is arranged（Contain 3 movable pulleys）, fixed pulley group（Contain 2 fixed pulleys）, equalizer pulley so that steel
Rope can be recovered to reel dextrorotation portion with the left-handed portion of self reel after fixed pulley, movable pulley, equalizer pulley are wound back and forth, dexterously solve
It the problem of existing headstock gear reel length of having determined and gate up and down balance system, theoretically can be by converting movable pulley and fixed pulley
Quantity and grooving number are accomplished not limited by reel length, have positive advantageous effect.
2nd, in the utility model, the cable trough in the left-handed portion of reel and dextrorotation portion is alternately set using spiral section and straightway
Put mode, so that levels steel wire rope can be stacked together in an orderly manner, alleviates the abrasion of steel wire rope, extends steel wire rope
Service life, reduce the maintenance cost in headstock gear later stage.
