The special-purpose boosting car of railway locomotive
Technical field
The present invention relates to a kind of boosting car, relate in particular to the special-purpose boosting car of a kind of railway locomotive, belong to railway locomotive tractor equipment field.
Background technology
At present railway locomotive depot, marshalling station and locomotive production unit usually need locomotive is cut to, and move and traction etc. the modes that adopt locomotive head traction, manpower traction or adopt the steel cable electric traction in the tradition more.Adopt the locomotive head traction more to the restriction in place, converting field fast, and also cost is higher.Adopt the manpower traction or adopt the mode working strength of steel cable electric traction big, efficient is low, is not suitable for the efficient of locomotive and moves and marshalling.If adopt locomotive head and devices such as motor special reductor and carrying cable, cost of equipment is higher, and the place to use is restricted, is not easy to the transfer of tractor equipment and moves, traction or to promote efficient low.
As Chinese patent notification number: CN201338650Y, the day for announcing: the utility model patent on November 4th, 2009 discloses a kind of booster, this booster is made up of actuating device and running gear etc., and running gear comprises three wheels, is respectively driving wheel, friction wheel, road wheel.Driving wheel contacts with friction wheel during work, and friction wheel contacts with road wheel, and driving wheel drives friction wheel, friction wheel advances with being pushed parts, friction wheel drives road wheel and advances with being pushed parts, and the utility model also comprises a dolly, this dolly direction scalable.But the driving wheel of this device is arranged on the below of friction wheel, and this device be pushed the contact site of equipment on the outside face of friction wheel, stressed contact point is higher, has the trend of upwards lifting in pushing course, makes friction wheel be easy to generate the phenomenon of bob, transmission is not steady, less stable, the friction force that friction wheel and road wheel can produce when walking is less, and friction wheel skids easily under the situation of overload, propelling thrust is little, is not suitable for promoting large-tonnage devices such as railway locomotive.
Summary of the invention
The objective of the invention is at existing railway locomotive move and during transition traction waste time and energy, operating efficiency is low, propelling thrust is little, in transmission process, be easy to occur skidding or jiggly defective of transmission and deficiency, a kind of compact conformation now is provided, move and the transition convenience, propelling thrust is big, the special-purpose boosting car of the railway locomotive that stable drive and operating efficiency are high.
For achieving the above object, technical solution of the present invention is: the special-purpose boosting car of railway locomotive, comprise vehicle body, motor, reductor, motor is installed on the vehicle body, on the output shaft of motor reductor is installed, on the mouth of reductor driving wheel is installed, it is characterized in that: the below of described driving wheel is equipped with first friction wheel and second friction wheel side by side, the outer round surface of first friction wheel and second friction wheel respectively with the outer round surface of driving wheel wipe contact mutually, leave the gap between first friction wheel and second friction wheel and the lower end tread is positioned on the same horizontal surface.
One end of described driving wheel passes the centre hole of end cap and the output shaft of reductor fixes, end cap is by on the outer face that is bolted to reductor, one end of first friction wheel and second friction wheel is installed in respectively on the end cap by bearing, the other end of first friction wheel and second friction wheel by bearing installation on side plate.
