Abstract

The invention discloses a control structure of a top drive device, which mainly solves the problem of the short service life of the motor of the existing top drive device, the large space occupied by the shut-off mechanism of the remote control internal blowout preventer, the large span of the tilting oil cylinder of the lifting ring, and the large span of the hydraulic control pipeline. complicated question. The control structure of the top drive device includes the main motor input transmission mechanism, the intermediate shaft transmission assembly connected with the main motor input transmission mechanism, and the kelly driven by the intermediate shaft transmission assembly, which is used for remote control internal defense in the kelly The shut-off mechanism of the injector, and the lubrication system used to control the lubrication of the lubrication points of the bearings in the structure. The control structure of the top drive device of the present invention improves the main motor input transmission mechanism of the top drive device, the shut-off mechanism of the remote control internal blowout preventer in the kelly, and the lubrication system of the gear box, and extends the main power of the top drive device. The service life of the motor makes the hydraulic pipeline of the shut-off mechanism simpler, saves space to a large extent, and makes the overall structure more compact.

Description

technical field [0001] The invention relates to the technical field of oil drilling, in particular to a control structure of a top drive device. Background technique [0002] Top drive is a new type of oil drilling machinery, which replaces the traditional rotary drilling, promotes the progress of drilling automation, and has become the standard equipment of oil drilling rigs. [0003] Among them, the main motor is the power source of the top drive, and the operation of its input transmission mechanism during the use of the top drive not only affects the service life of the motor, but also directly affects the normal operation of the entire top drive device. At the same time, as the core component of the transmission mechanism, the gearbox is very important to ensure the full lubrication of its lubrication points and the normal circulation of lubricating oil. The oil return cycle in the top drive device in the prior art usually installs an oil return pipe between the gear b...
