Title:
MOTOR DIRECT DRIVE DRAWWORKS
Document Type and Number:
WIPO Patent Application WO/2024/060016
Kind Code:
A1
Abstract:
The present application relates to the technical field of workover rig transmission devices, and specifically discloses a motor direct drive drawworks. The motor direct drive drawworks comprises a drawworks frame, a roller, a disc brake device and a variable-frequency motor; the roller is rotatably arranged on the drawworks frame; the disc brake device is connected to one end surface of the roller, and the disc brake device is arranged on the drawworks frame; the variable-frequency motor is connected to the other end surface of the roller, the variable-frequency motor is arranged on the drawworks frame, and an output shaft of the variable-frequency motor and the axis of the roller are coaxially arranged. The variable-frequency motor is used as a power source, thereby effectively avoiding the problems of serious noise and waste pollution; moreover, the output shaft of the variable-frequency motor and the axis of the roller are coaxially arranged, such that the transmission mechanism is simplified, lossless torque transmission can be implemented, and the transmission efficiency is improved.
