Abstract
The utility model is named as a fluid drive turntable which adopts an oil hydraulic motor to drive and a circular gear wheel train to transmit, and is mainly used in petroleum drilling operations. The utility model belongs to the petroleum drilling equipment technology technical field. The prior turntable adopts external power to undergo mechanical drive, and a drive system is a spiral bevel gear train, thereby the problems of low efficiency, complicated structure, difficult processing, bad reliability and economical efficiency exist. The utility model adopts hydraulic pressure to drive to achieve infinite variable speed and constant power output of the turntable, which improves efficiency, increases reliability and economical efficiency with the circular gear wheel train simplified structure, and solves the technical problem of the prior turntable.
Description
Affiliated technical field
The utility model is the parts that are used for rotary drilling in the petroleum drilling operation, and it will rotatablely move and be passed to the drill bit of down-hole, so that fractured rock, reaches the purpose of degree of depth drilling well.
Background technique
At present, its power of traditional rotating disk is to be delivered to the rotating disk horizontal axis from winch by cardan shaft or sprocket wheel, and horizontal axis is delivered to turntable by helical bevel gear again, drives drilling rod by turntable and rotates.The kind of drive of this structure is a Mechanical Driven, and power reduces efficient through a plurality of transmissions; The large-scale spiral bevel gear drive is paid, and requires to have higher machining level.
Summary of the invention
For the Mechanical Driven mode and the complicated structure that change traditional rotating disk, the utility model provides a kind of hydraulic driving rotating disk, and this rotating disk adopts hydraulic driving mode and cylindrical gears to replace original mechanical transmission and helical bevel gear.Hydraulic driving mode is a kind of flexible transmission, makes rotating disk realize stepless change and the output of permanent power; Column gear transmission is paid, and is easy to processing and precision height, has improved reliability and Economy.
The technological scheme that its technical problem that solves the utility model adopts is: oil hydraulic motor as power through the turntable of deceleration cylindrical gears transmitting movement to rotating disk, turntable is by the master bushing rotation of the square hole drive various sizes of self, the kelly bar that insert in the master bushing this moment just moves together in company with turntable, the below of kelly bar is through the drilling rod that is being threaded, drill bit, when the driller personnel put on pressure on the drill bit, just produced drillng operation.
