Taking the ZJ90DB oil drilling rig as an example,this paper comprehensively considers the motor characteristics of the drawworks and the safety requirements of the traveling drawworks operation. It studies the calculation and selection of the maximum hook speed of the variable frequency control system of the oil drilling rig drawworks,calculates the braking capacity requirements and braking unit configuration during the drawworks lowering process,and conducts relevant on-site operation verification.
