Abstract

An example drawworks may include an electrical drive motor and an output shaft driven by the electrical drive motor. A worm gear may be coupled to the output shaft and a bull gear may be engaged with the worm gear. A wireline drum may be coupled to the bull gear and receive rotation from the electrical drive motor through the bull gear.

Description

[0001] cross application statement [0002] This application is based upon and claims the benefit of priority from US Provisional Application No. 61 / 803730, filed March 20, 2013, the entire contents of which are hereby incorporated by reference. Background technique [0003] Drawworks units have been operated on drilling rigs since the dawn of the drilling industry. Over the years there have been some developments in the power and speed of winch units, making them more powerful and more controllable. [0004] The basic structure of the device has remained largely the same throughout this time. The winch unit employs: a gearbox driven by an electric motor unit through which the former is mechanically connected to the winch drum for winding up and down the line of the drilling rig. Over time, deploy safety devices to guarantee safe control of winch failures. [0005] Typically, electric motors can be direct current (DC) or alternating current (AC) drives. In more recent time...
