Coupler guiding device

The utility model relates to a coupler guiding device whose coupler is provided with a knuckle. The utility model is characterized in that one side of the coupler of the vehicle pushing and shifting machine is provided with a coupler guiding section. The guiding section can be directly welded on one side of an ordinary coupler. The guiding section can also be formed by directly lengthening one side of the ordinary coupler as soon as the coupler is manufactured. To solve the problem that the deflection of the coupler is too big, a coupler centre line which is arranged on the vehicle pushing and shifting machine can be moved in a proper distance in overturning direction (deflecting direction of the coupler on a flat car) and is misaligned with a vehicle body centre line. A proper distance is provided between the two centre lines. The coupler guiding device can assure the coupler of the vehicle pushing and shifting machine to be correctly led in the coupler of a vehicle which is pushed and shifted when the coupler of the flat car is in the two deflection boundaries, can assure not to collide with any accessories of the flat car in any state, and can realize automated job.
