Frequency conversion stepless rope continuous tractor

The utility model relates to mine haulage machinery, in particular to a stepless rope continuous tractor. The speed of the stepless rope continuous tractor is adjusted through a frequency converter. The frequency conversion stepless rope continuous tractor mainly comprises the frequency converter, a hydraulic power unit, a winch, a heavy punch tensioning device, a hydraulic tensioning device and the like. The winch mainly comprises an electromotor, a speed reducer, a last-step small gear and a last-step big gear. The speed can be changed freely during an operation process through the frequency converter, stepless speed changing can be achieved, and remote control can be achieved. A composite tensioning mode is used in the stepless rope continuous tractor, tensioning force and a tensioning stroke are large, and tensioning is quick, convenient and reliable.
