Abstract
The invention discloses a pipe processor driving device for a top drive. The pipe processor driving device comprises a hydraulic motor and a worm wheel and worm transmission structure. A worm wheel is fixedly arranged on the upper portion of a rotating head, an output shaft of the hydraulic motor is connected with a worm and transmits power to the worm wheel to drive the rotating head to move. The pipe processor driving device is high in reliability and can position the rotating head by any angle. On the premise of keeping normal functions, the integral structure of the pipe processor driving device is simplified.
Description
Technical field
The present invention relates to a kind of top drives with pipe processor drive unit.
Background technology
As Fig. 1, Fig. 2, shown in Figure 3, the pipe processor device is driven by installation compositions such as swivel head, IBOP, back-up tongs in the top.Pipe processor topmost is swivel head 1, and swivel head 1 can rotate, and then drives suspension ring 12 and elevator motion, on drilling floor surface, drilling tool is carried out a series of operation, serves as the effect of manipulator.
Rotatablely moving of the pipe processor that drive on existing top is by gear engagement transferring power, by hydraulic motor 2 driving pinions, and the canine tooth wheel disc 3 on a driven rotary top.Have in uniform way several through holes 4 on toothed disc 3.Because gear-driven transmission is smaller, the power that is come by hydraulic motor transmission must through the compound gear double reduction, make complicated integral structure and affect transmission efficiency.When drilling tool is gone up, during shackle, must holding tube sub-processor integral body static, bear the reaction torque of bringing when back-up tong clamps drilling tool.Therefore, need to settle separately hydraulic cylinder, Driven by Hydraulic Cylinder is penetrated pin, insert in the through hole 4 of toothed disc, swivel head is locked, make it to maintain static, but this has increased the complexity that structure is driven on the top in the middle of invisible, while is due to the existence of hydraulic mechanism, sealing ring and jump ring in hydraulic cylinder are consumable accessorys, often damage stuckly, have brought trouble to maintenance work, waste time and energy, have a strong impact on drilling progress.
Summary of the invention
For the problem that prior art exists, the object of the present invention is to provide a kind of structure to drive with pipe processor drive unit through the top of simplifying.
For achieving the above object, the present invention drives on the top with pipe processor drive unit, comprises hydraulic motor and turbine and worm drive mechanism, wherein, turbine is fixedly installed on the top of swivel head, and hydraulic motor output shaft is connected with worm screw, transmission of power to turbine, and then is driven the swivel head motion.
Further, described turbine and worm drive mechanism is twice-enveloping line vortex worm and gear.
The present invention adopts the turbine and worm gearratio large, and the power of exporting through hydraulic motor need not through double reduction, therefore simplifies the structure, and has improved transmission efficiency.With respect to the typical turbine worm screw, the twice-enveloping line vortex worm and gear total number of teeth in engagement that the design adopts is many, and transmission is more steady.Due to the distinctive reverse self-locking function of turbine and worm, be that worm screw can drive turbine, and turbine can't drive worm screw, like this when carrying out upper shackle, if allow swivel head keep static, need not any operation, bear reaction torque on back-up tong by worm screw, reliability is higher, and can be at the positioned at arbitrary angles swivel head.Satisfying under the prerequisite of normal function, realizing integrally-built simplification.

The specific embodiment
Below, with reference to accompanying drawing, the present invention is more fully illustrated, shown in the drawings of exemplary embodiment of the present invention.Yet the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make the present invention comprehensively with complete, and scope of the present invention is fully conveyed to those of ordinary skill in the art.
In order to be easy to explanation, here can use such as " on ", the space relative terms such as D score " left side " " right side ", be used for element shown in key diagram or feature with respect to the relation of another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device in figure is squeezed, be stated as the element that is positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, the exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and the relative explanation in space used here can correspondingly be explained.
As extremely shown in Figure 7 in Fig. 4, the present invention drives on the top with pipe processor drive unit, comprise hydraulic motor 5 and turbine and worm drive mechanism, wherein, turbine 7 is fixedly installed on the top of swivel head, hydraulic motor 5 output shafts are connected with worm screw 6, and transmission of power to turbine 7, and then is driven swivel assembly 8 motions.In the present invention, the pipe processor comprises swivel assembly 8, IBOP 9, back-up tong 10 and suspension ring 11, and the design has removed traditional gear engagement mechanism and driven the swivel head motion, the substitute is twice-enveloping line vortex worm and gear.
Because the turbine and worm gearratio is large, the power of exporting through hydraulic motor need not through double reduction, therefore simplifies the structure, and has improved transmission efficiency.With respect to the typical turbine worm screw, the twice-enveloping line vortex worm and gear total number of teeth in engagement that the design adopts is many, and transmission is more steady.Due to the distinctive reverse self-locking function of turbine and worm, be that worm screw can drive turbine, and turbine can't drive worm screw, like this when carrying out upper shackle, if allow swivel head keep static, need not any operation, bear reaction torque on back-up tong by worm screw, reliability is higher, and can be at the positioned at arbitrary angles swivel head.Satisfying under the prerequisite of normal function, realizing integrally-built simplification.
