The utility model content
The purpose of this utility model provides a kind of oil-well rig hydraulic swivel head, and solve prior art and adopted machine driving, the structure more complicated, transmission link is many, power consumption is big, the problem that manufacturing cost is high.
The technical scheme that the utility model adopted is, a kind of oil-well rig hydraulic swivel head, comprise rotation table device, rotation table device is installed on the base by base bearing, the inner periphery of rotation table device is set with the main core of mending, the main inner periphery of mending core is set with mends the core lining, and the master mends core and mends between the core lining and is provided with check mechanism; Rotation table device also is connected with the power shaft assembly by cylindrical gear pair, and the power shaft assembly is connected with hydraulic system, and the upper surface of rotation table device and power shaft assembly is provided with loam cake.
Oil-well rig hydraulic swivel head of the present utility model, its feature also is:
Described oil-well rig hydraulic swivel head also comprises lubricating system, is communicated with respectively with base bearing, cylindrical gear pair, power shaft assembly.
Described cylindric spiral gear adopts the involute cylindric spiral gear.
Described base bearing is selected the annular contact thrust ball bearing of major-minor bearing one for use.
The beneficial effect of the utility model device is, adopted hydraulic-driven, saved the complicated mechanical driving-chain like this, have high moment of torsion, big latus rectum, the slow-speed of revolution, transmission compactness, save the space, in light weight, be easy on the rig floor face, to arrange and control system is simple, configuration rates is low characteristics, satisfy offshore rig and using marine riser, rotating disk function when drive on the top.
Description of drawings
Fig. 1 is the hydraulic swivel head structural representation of the utility model device;
Fig. 2 is the assembly structure schematic diagram of the C direction among Fig. 1.
Among the figure, 1. loam cake, 2. base, 3. rotation table device, the 4. main core of mending, 5. check mechanism is 6. mended the core lining, 7. base bearing, 8. cylindric spiral gear, 9. power shaft assembly, 10. hydraulic system, 11. lubricating systems.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, the structure of oil-well rig hydraulic swivel head of the present utility model is: comprise loam cake 1, base 2, rotation table device 3, the main compositions such as core 4, check mechanism 5, benefit core lining 6, base bearing 7, cylindric spiral gear 8, power shaft assembly 9, hydraulic system 10, lubricating system 11 of mending.Rotation table device 3 is installed on the base 2 by base bearing 7, and the inner periphery of rotation table device 3 is set with the main core 4 of mending, and the inner periphery that the master mends core 4 is set with benefit core lining 6, and main the benefit between core 4 and the benefit core lining 6 is provided with check mechanism 5; Rotation table device 3 also is connected with power shaft assembly 9 by cylindrical gear pair 8, and power shaft assembly 9 is connected with hydraulic system 10, and the upper surface of rotation table device 3 and power shaft assembly 9 is provided with loam cake 1.As Fig. 2, be the assembly structure schematic diagram of the C direction among Fig. 1, hydraulic swivel head also comprises lubricating system 11, lubrication circuit is communicated with respectively with base bearing 7, cylindrical gear pair 8, power shaft assembly 9.
3 of the rotation table devices of big latus rectum are placed on the base bearing 7 of major-minor one form, under the control of compact conformation, the simple hydraulic system 10 of control, power shaft assembly 9 drives involute cylindric spiral gear 8 and helps the turntable rotation, and bears the maximum static lotus, finishes the rotating disk function of offshore rig.
The base bearing 7 of hydraulic swivel head is selected the annular contact thrust ball bearing (non-standard) of major-minor bearing one for use, and it mainly works to help the turntable rotation, bears the vibration force of gear mesh force and kelly bar swing; When casing job, base bearing 7 will bear the static load 11250kN that is equivalent to max. hook load; When normally creeping into, bear kelly bar and pass to the dynamic loading that rotary bushing 4 and rotation table device 3 have certain impact to lower slider.Base bearing 7 after determining satisfies requirement reliably such as load-bearing, rotation.
Mend core 4 by the main of monolithic construction, and adopt the joining mode of straight pin between the turntable, transmit operation torque up 70000Nm.
With the spiral bevel gear that involute cylindric spiral gear 8 has replaced conventional rotating disk to use, though bevel gear has stable drive, contact stress is little, the supporting capacity height, and advantage such as meshing performance is good, large diameter bevel gear is difficult to operation in processing.And the involute cylindric spiral gear of selecting for use 8 makes the processing technology of gear simple outside performance that satisfy to transmit high-power, high pulling torque, low speed rotation.
The drive system of rotating disk is driven by complicated mechanical and becomes fairly simple hydraulic-driven 10.Conventional rotating disk all be by the transmission chain length, that parts are many, the complete machine quality is big is mechanically operated, also has factors such as difficult arrangement on marine drilling platform.And the hydraulic system structure compactness of selecting for use, control are simple, in light weight, and are easy to arrange on the rig floor face because of floor space is little.
The rotating disk lubricant housings is more, and the bearing in 11 pairs of base bearings 7 of lubricating system and roller gear 8, the power shaft assembly 9 etc. all can be realized good lubricating.
Rotary speed of the present utility model is lower, has adopted hydraulic-driven, has saved the complicated mechanical driving-chain, have the transmission compactness, the space is little, and is in light weight, be easy on the rig floor face to arrange and control system simple, characteristics such as configuration rates is low, this is very desirable equipment for marine drilling platform.The hydraulic swivel head latus rectum is big, carry high and low rotating speed, can satisfy offshore rig, particularly using marine riser, rotating disk function when drive on the top, can improve the ability to provide the auxiliary items of ocean ultradeep well rig.
