| description | The invention discloses a control structure of a top drive device. The control structure mainly solves the problems that a motor of an existing top drive device is short in service life, a remote control inner blowout preventer shutdown mechanism is large in occupied space, the span of a lifting ring inclined oil cylinder is large, and a hydraulic control pipeline is complex. The control structureof the top drive device comprises a main motor input transmission mechanism, a middle shaft transmission assembly connected with the main motor input transmission mechanism, a kelly bar driven by themiddle shaft transmission assembly, a shutdown mechanism used for a remote control inner blowout preventer in the kelly bar, and a lubricating system used for controlling lubricating points of bearings in the structure to be lubricated. According to the control structure of the top drive device, the main motor input transmission mechanism of the top drive device, the shutdown mechanism of the remote control inner blowout |
