Abstract
The utility model discloses a hydraulic dial used in oil drills. The hydraulic dial is suitable for various and sizes of drills to complete the drilling operation adopting square drill pipe and is composed of hydraulic powered, hydraulic controlled and hydraulic implementing systems and mechanic parts. The application of the hydraulic technique makes it possible for the dial to apply the power of generating machines to the utters degree and to realize a low speed and a big torque moment, a speed change without grade, a constant torque moment and highly active, safe and fast drilling operation, the operation having the property of automatic protection when met with tight pull or is overload. What is more important, the use of the hydraulic dial simplifies the power transmission chain and reduces the volume of the drill. Besides, the utility model also has the advantages that the installment and transportation are convenient; the error rate is reduced and the reliability is improved.
Description
Technical field
The utility model belongs to a kind of oil-well rig, the improvement of the rotating disk that a kind of specifically oil-well rig is used.
Technical background
At present, oil-well rig mainly adopts Mechanical Driven with rotating disk, be that the power that diesel engine or motor provide passes through transfer case or winch axle, again through the complicated transmission mechanism (sprocket wheel, gear, shaft coupling, universal drive shaft, right angle gear box, air clutch etc.) of a cover, drive disk operation by pinion and a gear wheel engagement at last, indivedual rigs also have employing motor drive, and promptly motor drives a plurality of pinions and a gear wheel engagement driving disk operation by shaft coupling.Present these two kinds of type of drive that adopt, adopt Mechanical Driven, the L type series mechanical rig that particularly inexpensive domestic sales volume is bigger, the power of its rotating disk is by the air clutch on the winch, chain, right angle gear box, the climbing universal drive shaft of AM/BAM, right angle gear box below the rig floor, rotating disk driving box, universal drive shaft, the rotating disk transfer transmits the driving-chain complexity with mechanisms such as passing through the air clutch of stopping, mechanism is huge, the Installation and Debugging difficulty, transmission efficiency is low, poor reliability.Adopt the motor drive, the expense height, the rig floor face need strengthen, and brings difficulty for installation and transportation.
Summary of the invention
The purpose of this utility model provides a kind of oil-well rig hydraulic swivel head; utilize the advantage of hydraulic technique; reduce the rotating disk input power; when the processing accident, accomplish low-speed big; creeping into when being hampered the automatic reduction of speed of rotating disk up to the stall overload protection; realize the control of rotary drilling weighing apparatus power, dial stepless timing control makes drillng operation safety, efficient.
Specifically, the utility model is achieved in that a kind of oil-well rig hydraulic swivel head, hydraulic control unit of controlling by the hydraulic power mechanism that power is provided for whole device, to the dial rotation mode and the hydraulic actuating mechanism that drives the rotating disk action are formed, hydraulic power mechanism power taking and be communicated with hydraulic actuating mechanism by hydraulic control unit and hydraulic line from the compound chain case.
Described hydraulic power mechanism is made of compound box unit head (1), hydraulic pump (2), tank mounting (3), compound box unit head (1) meshes transmission of power in control module with the engagement power taking of compound box drive chain case and with hydraulic pump (2), and hydraulic pump (2) is communicated with tank mounting (3) by hydraulic fluid pipeline.
Described control module comprises control valve assembly (4) and the pressure meter (5) that is installed on the hydraulic fluid pipeline.
Described executing agency is made of hydraulic motor (6), speed reducing gear pair and rotating disk mechanism (7), and hydraulic motor (6) drives rotating disk mechanism by reduction gearing and rotates under controlling organization control.
Adopt one or more low speed high torque hydraulic motors and pinion and a gear wheel engagement directly to drive disk operation.
Adopt one or more discharge capacities, high pressure, bidirectional variable plunger displacement pump to provide hydraulic swivel head work required power.
The forward and backward of hydraulic swivel head transfers realization by hydraulic pressure hand control valve remote control bidirectional variable plunger displacement pump positive and negative.
The brake of hydraulic swivel head, parking are realized by hydraulic valve.
But the work of hydraulic motor separate unit or many work simultaneously, but also separate unit work or many s' bidirectional variable plunger displacement pump simultaneously work.The arbitrary combination of pump and motor can make needs under different rotating speed, moment of torsion, power the efficient operation of hydraulic swivel head according to drilling well.
Oil-well rig is adapted to the oil field oil-well rig with hydraulic swivel head and adopts kelly bar to finish all kinds of drillng operation, the rig of specification, because the use of hydraulic technique, this rotating disk has maximally utilised the power of engine, has realized efficient, the safety of low-speed big, infinitely variable speeds, permanent moment of torsion and the automatic overload protection that is hampered, drillng operation fast; The more important thing is the use of this hydraulic swivel head, can simplify the power chain of rig, the rig volume is reduced, install and convenient transportation, fault rate reduces, and reliability improves, and greatly reduces cost simultaneously.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
The utility model hydraulic swivel head is made up of hydraulic power, hydraulic control, hydraulic actuating mechanism, hydraulic power system is made of compound box unit head (1), hydraulic pump (2), tank mounting (3), control module is made of control valve assembly (4), pressure meter (5), and executing agency is made of hydraulic motor (6), speed reducing gear pair and rotating disk mechanism (7).When drillng operation, drive hydraulic pump (2) by compound box unit head (1), hydraulic pump (2) is discharged hydraulic oil suck hydraulic oil from tank mounting (3) after, hydraulic oil reaches control valve assembly (4) by pipeline, regulate rear drive hydraulic motor (6) through control valve assembly (4), hydraulic motor (6) and pinion and a gear wheel engagement drive rotating disk (7) work.
Claims (1)
1, a kind of oil-well rig hydraulic swivel head, the hydraulic actuating mechanism that it is characterized in that the hydraulic control unit of controlling by the hydraulic power mechanism that power is provided for whole device, to the dial rotation mode and drive the rotating disk action is formed, hydraulic power mechanism power taking and be communicated with hydraulic actuating mechanism by hydraulic control unit and hydraulic line from the compound chain case; Hydraulic power mechanism is made of compound box unit head (1), hydraulic pump (2), tank mounting (3), compound box unit head (1) meshes transmission of power in control module with the engagement power taking of compound box drive chain case and with hydraulic pump (2), and hydraulic pump (2) is by hydraulic fluid pipeline and tank mounting (3); Control module comprises control valve assembly (4) and the pressure meter (5) that is installed on the hydraulic fluid pipeline; Executing agency is made of hydraulic motor (6), speed reducing gear pair and rotating disk mechanism (7), and hydraulic motor (6) drives dial rotation by reduction gearing.
