Description

A kind of oil-well rig middle-deep well is with rotating disk master bushing device

Technical field

The utility model belongs to sea oil drilling and production equipment technology field, relates to a kind of oil-well rig middle-deep well with rotating disk master bushing device.

Background technology

Rotating disk is the vitals in the oil-well rig equipment, and main bushing then is requisite parts in the turntable structure, and it plays a part support drilling tool weight, transfer torque, dwindles the rotating disk opening.The main bushing of existing conventional rotating disk, be split type structure, be connected with the ear formula with turntable, the rotating disk master bushing of this structure has easy to process when latus rectum, load, moment of torsion are all little, advantages such as simple are installed, but also there are problems such as yielding, that installation accuracy is low in the connection of ear formula.At present, become the main product in petroleum drilling and mining market at the middle-deep well rig after, dispose big latus rectum, high moment of torsion, big load rotating disk has just become inevitable.

The utility model content

The purpose of this utility model provides a kind of oil-well rig middle-deep well with rotating disk master bushing device, solved have processing in the prior art and when using master's bushing easily produce deformation, problem that installation accuracy is low.

The technical scheme that the utility model adopted is, a kind of oil-well rig middle-deep well is with rotating disk master bushing device, comprise rotation table device, rotation table device is set with main bushing, bushing device, bushing successively in the axle center, be provided with check mechanism in the cavity between wherein main bushing and the rotation table device, adopt pin to be connected between main bushing and the rotation table device.

Rotating disk master bushing device of the present utility model, its feature also is:

The structure of described main bushing is a monolithic construction.

Described main bushing is connected with rotation table device by the pin of four column types.

The beneficial effect of the utility model device is, bushing is easily processed, the intensity height, and stability of rotation, noise are low, use reliable, safety, efficient, extends to bigger load, more on the rotating disk of high pulling torque, bigger latus rectum.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, rotary bushing apparatus structure of the present utility model is to comprise that rotation table device 1, check mechanism 2, main bushing 3, bushing device 4, bushing 5, pin 6, hold-down screw 7 constitute.Rotation table device 1 is set with main bushing 3, bushing device 4, bushing 5 successively in the axle center, be provided with check mechanism 2 in the cavity between wherein main bushing 3 and the rotation table device 1, adopt the pin 6 of column type to be connected between main bushing 3 and the rotation table device 1, with transfer torque, pin 6 is regulated by hold-down screw 7 and is fixing.

With reference to Fig. 2-Fig. 6, the interior latus rectum of bushing 5 then is complementary a size and a little specification rotating disk master bushing for improving the bushing utilization rate, has realized the transition of two kinds of rotating disk masters bushing; In addition,, consider the stand under load feature and the driving part of main bushing, optimized the inner-cavity structure of main bushing, make its easy processing and manufacturing in order to alleviate rotating disk weight, easy to install.

The structure of main bushing 3 is monolithic constructions, is different from the dissection type of conventional rotating disk.Not yielding when bearing big load, high moment of torsion and processing use, and, optimized inner-cavity structure satisfying under the prerequisite of function, reduced total quality.

Integrated main bushing 3 utilizes four pins 6 to be connected with rotation table device 1 and drives, and has satisfied the ability of rotating disk transmitting large torque.

The endoporus of integrated main bushing 3 is complementary with the rotary bushing device 5 of time one-level specification, thereby No. 3, No. 1, No. 2, API, API, 20 that makes API " and 30 " bushing is suitable for the different size rotating disk simultaneously, successfully realize the transition of main bushing device between the rotating disk, unified the bushing specification.

The integrated main bushing 3 inner check mechanism of installing 2 can axially pin turntable and main bushing device, bushing, to satisfy the needs that prevent the rotating disk axial motion when drillng operation tube connector string makes a trip, have reached the requirement of safety operation.

The utility model device, master's bushing easily produces the technical barrier of deformation when having solved processing and use, satisfy in the middle-deep well drilling equipment big load to the rotating disk requirement, high pulling torque, big latus rectum function and can be according to the operating mode demand, adopt different bushing combinations, improve the utilization rate and the versatility of bushing.The power of Rotary table for drilling machine is by the power shaft input, passes to the purpose that drilling tool reaches drilling well by parts such as bevel gear pair and turntable, main bushings, and successfully be used on 12000 meters supporting rotating disks of rig of national 863 projects, be specially adapted to of the application of middle-deep well rig with high pulling torque, big latus rectum, big load rotating disk.
