Abstract

The invention discloses a motor direct-drive type alternating current frequency conversion winch for oil field well drilling. The motor direct-drive type alternating current frequency conversion winchcomprises a winch base rotationally provided with a winch roller. Each of the two ends of the winch roller is provided with an end shaft. Each end shaft is externally provided with an alternating current frequency conversion motor fixed to the winch base, wherein the alternating current frequency conversion motor and a roller shaft are connected through a coupler. One or more brake discs are arranged outside the winch roller and used for braking of the winch roller. Transmission chain composition of the motor direct-drive type alternating current frequency conversion winch for oil field welldrilling is simple, and the transmission efficiency is high; and integral size is small, the weight is small, and running noise is low.

Description

technical field [0001] The invention belongs to the technical field of drive equipment, and in particular relates to a motor direct-driven AC frequency conversion drawworks for oil field drilling. Background technique [0002] The AC variable frequency winch is widely used in the field of oil drilling rigs due to its advantages such as wide speed range, fast response, strong overload capacity, and easy automatic control. At present, the AC variable frequency winch drives the winch drum shaft by the motor through the gear reducer, and realizes the lifting and lowering functions of the winch through the control system, but there are still relatively low transmission efficiency, low lifting and lowering efficiency, large size and weight, and maintenance. problems such as heavy workload. With the development of motor manufacturing technology and frequency conversion control technology, motor direct drive technology has developed rapidly, and has been applied in the machine tool...
