Description
Technical field:
The utility model relates to the oil drilling top-drive drilling, specifically, is that a kind of electricity of new structure drives top driving device.
Background technology:
At present, the top-drive device power swivel is the core component of top driving device, generally by motor (direct current or interchange) or hydraulic motor and reduction box formation.Motor directly links to each other with gear reduction box, by the one-level or the rotary drilling of double reduction rear drive case inner main axis of reduction box.Reduction box has lifting load, transmits and bears multiple functions such as moment of torsion, circulating mud in entire work process, need gear, bearing are lubricated a series of relevant issues such as the cooling of solution lubrication oil, filtration, sealing simultaneously.Its complex structure of the reduction box of top driving device, difficulty of processing is big, and manufacturing cost is higher, because its important function is therefore also very high to its maintenance cost.
Summary of the invention:
The purpose of this utility model is to provide a kind of electricity of new structure to drive top driving device, it can effectively improve the top and drive performance, and make structure simpler, be more convenient for safeguarding, the present invention is intended to simplify the power swivel structure, the alternating current generator that designs a kind of special construction directly drives drill string rotating and creeps into, and drives motor and the reduction box structure that generally adopts to replace present top.The superiority of the power swivel of this structure is to have omitted reduction box, has improved a series of problems such as lubrication oil cooling, sealing, and the processing and manufacturing difficulty reduces significantly, easy accessibility, and maintenance is raised the efficiency easily, is the top driving device of a green energy conservation.
The utility model is achieved in that by two big parts to be formed: power swivel 1, and pipe processor 2, power swivel 1 is connected by main shaft 7 with pipe processor 2.
The electric machine structure of power swivel 1 is made up of armature spindle (output shaft) 3, stator 4.Magnet is sticked in armature spindle 3 outsides, is fixedly linked with main shaft 7 in the armature spindle 3.The interior cover 5 and the power swivel connector 6 of pipe processor 2 are connected and fixed.
There is the electromagnetism winding motor stator 4 inboards, and its shell promotes power swivel connector 6 with the lower end and directly links to each other.
The bearing that all has up and down of armature spindle 3 is set upright, and there is a high thrust loading ability of bearing lower end simultaneously.Output shaft 3 upper ends are connected with the washing pipe assembly, and the lower end links to each other with automatic and manual IBOP, is connected with drilling rod again.
The utility model is compared with the traditional design scheme has following advantage:
1) the motor direct-drive main shaft creeps into, no reduction box device and gear lubricant and cold filtration system, and simple in structure, processing and manufacturing is easy, and is easy to maintenance;
2) overall structure is simple, the reliability height of complete machine work.
Have promotional value, can satisfy the needs of 150～1000 tons of top drive systems, application prospect is boundless.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, form by two big parts: power swivel 1, pipe processor 2, power swivel 1 is connected by main shaft 7 with pipe processor 2.
The electric machine structure of power swivel 1 is made up of armature spindle (output shaft) 3, stator 4.Magnet is sticked in armature spindle 3 outsides, is fixedly linked with main shaft 7 in the armature spindle 3.Main shaft 7 adopts hollow structure, allows mud to pass through.There is the electromagnetism winding motor stator 4 inboards, and its shell promotes power swivel connector 6 with the lower end and directly links to each other.The bearing that all has up and down of armature spindle 3 is set upright, and there is a high thrust loading ability of bearing lower end simultaneously.Output shaft 3 upper ends are connected with the washing pipe assembly, and the lower end links to each other with automatic and manual IBOP, is connected with drilling rod again.
The direct output speed of this power swivel 1 is 0～250r/min, is fit to the requirement of drilling technology, and its peak torque is the twice (zero to rated speed) of the conventional motor that uses simultaneously, can satisfy the needs of maximum shackle moment of torsion.Because the direct transmission of motor so need not lubricating arrangement, only needs regularly to get final product at each bearing place grease up.
The interior cover 5 and the power swivel connector 6 of pipe processor 2 are connected and fixed, transmitted load and carrying shackle moment of torsion.The effect of pipe processor 2 is can carry out the drilling rod extracting and go up shackle, and its structure and other top are driven roughly the same.
