Description

Independent driving device for turntable Technical Field The utility model relates to the technical field of petroleum drilling equipment, in particular to an independent driving device for a turntable. Background The turntable is one of important equipment in the petroleum drilling machine, the transmission principle of the existing electric drive turntable independent driving device is that a motor inputs power into a reduction gearbox through a coupler, the turntable is driven to work through a universal coupler after gear reduction, the turntable is limited by the structure of the gear reduction gearbox, an input shaft of the motor and an input shaft of the turntable can only be oppositely arranged, the whole length of the turntable independent driving device is long, and the size of a base required to be installed is large. With the wide application of electric workover rig, electric drive carousel independent drive arrangement is generally with the supporting installation of electric workover rig, because electric drive carousel independent drive arrangement is small in base size, and the model size of each part is adjusted to the time spent in every time installation to avoid electric drive carousel independent drive arrangement's length to surpass the base size, lead to electric drive carousel independent drive arrangement's installation effectiveness on the base very low.
