The present invention has following beneficial effect:
1, utilize draw-gear of the present invention can effectively prevent derailing of mine car in distraction procedure, realized heavy grade (12 °-15 °) traction of rubber-tired cart to orbit mine car, compared with traditional track drawing mode, gradient application surface is wider;
2,, compared with traditional hawser mode of traction, the orbiting motion of rubber-tired cart is freer, operational sequence is simpler, propulsive efficiency is higher;
3, the small rail car of described draw-gear can move left and right along slide rail, effective compensation the teeter in rubber tire tractor process, prevent that mine car from derailing because of teeter;
4, between rotating turret and wheel carrier for bearing pin connects and form revolute pair, rotating turret can rotate up and down around bearing pin, effective compensation rubber-tired cart climb and fall out-of-date, orbit mine car, along the swing of horizontal sextant angle direction, prevents that mine car is because of the derailing of beating;
5, between the traction piece of this device and rotating turret for bearing pin is connected and form cylindrical sleeves pair, traction piece can rotate moving frame rotate, effective compensation the tractor lateral tilting gradient (torsion) causing because of Uneven road etc., prevent that railcar from toppling, and between traction piece and rotating turret, be provided with the buffering auxiliaries such as block rubber, solved orbit mine car impulsive force to traction rubber-tired cart in starting and braking procedure;
6, this device is to be connected with orbit mine car by the engaging lug of traction piece end, be connected with rubber-tired cart main car frame by slide rail, and easy accessibility, and can realize the traction of any rubber-tired cart to different size orbit mine car by this device, applied widely.
In summary, utilize draw-gear of the present invention can realize being fast connected and traction function of rubber-tired cart and orbit mine car, can realize the effective compensation of the torsional deflection of teeter, bob and rubber-tired cart to rubber-tired cart simultaneously, both effectively utilized that rubber-tired cart adhesive force is large, driving power is strong and the feature such as climbing capacity is large, and can effectively ensure again mine car even running in orbit.
