Abstract
The utility model discloses an autorotation oil well sleeve, belongs to the field of matched machines for oil exploitation and mainly solves the problem that oil pipes are easy to wear in existing oil exploitation process. The autorotation oil well sleeve structurally comprises a motor, a base, a driving gear, a driven gear, an oil pipe joint, a bearing, a cover plate and bolts. An output shaft of the motor is fixedly connected on the driving gear, the driving gear and the driven gear are arranged on the same horizontal plane, the oil pipe joint penetrates the center of the driven gear, the bottom end of the oil pipe joint is supported by the bearing, the integral structure of the autorotation oil well sleeve is covered by the cover plate, and the cover plate is fixed on the base through the bolts. During use, the oil pipe joint is driven to rotate by the motor, so that a sucker rod and a round pipe can stay relative rotation station in the crude oil exploitation, wear during operation tends to be uniform, and service livers of the oil pipe of an oil well mouth and the sucker rod are prolonged.
Description
Technical field
The utility model relates to a kind of rotation type oil well cover, belongs to oil exploitation supporting machinery field.
Background technology
In oil exploitation process, wellhead for production is the visual plant recovering the oil, and well mouth of oil well device affects oil extraction.Wellhead for production mainly contains concentric wellhead for production and eccentric oil production well mouth device.Decentralized wellhead is mainly to solve to recover the oil and test problem, and tubing string has certain eccentric throw in down-hole, thereby realizes annulus logging by rotary portal.And production wellhead is generally non-rotatable with one heart, if rod string and oil pipe decentraction, easily cause the wearing and tearing of rod string and oil pipe, because tubing string is non-rotatable, therefore very easily cause the local eccentric wear of oil pipe, time one is long, easily cause oil pipe to lose efficacy, thereby directly affect the production of oil well.
Utility model content
The utility model, for oil pipe problem easy to wear in current oil exploitation process, has designed a kind of rotation type oil well cover.
The technical scheme in the invention for solving the technical problem is:
This rotation type oil well cover comprises motor, pedestal, driven wheel, driven gear, oil connection, bearing, cover plate, bolt; Motor output shaft connects firmly on driven wheel, and driven wheel and driven gear are positioned in same level, and oil connection is through driven tooth core wheel portion, and oil connection bottom supported by bearing, and a whole set of structure is covered by cover plate, and cover plate is bolted on pedestal.
There is the groove that holds driven wheel and driven gear at described pedestal middle part, and pedestal integral body is rectangle, and corner location is respectively provided with a bolt hole.
Described motor is vertically placed, and output shaft is connected by key connected mode with driven wheel.
Cylindrical structural is arranged at described oil connection bottom, and oil connection is through driven tooth core wheel portion hole, and the mode being connected by key between driven gear and oil connection connects, and flange arrangement is arranged at oil connection top.
There is screwed hole at described cover plate edge, between cover plate and pedestal, by bolt, is connected.
The utility model has the following advantages:
1. the utility model is novel unique, driving effect by motor in use procedure is rotated oil connection, make in oil extraction process between sucker rod and pipe, in state in relative rotation, to make the wearing and tearing in the course of work be tending towards the application life that homogenising has improved oily well mouth oil pipe and sucker rod.
2. material is cheap, and cost of manufacture is low, and application is wide.
Accompanying drawing explanation
Fig. 1 is the whole sectional drawing of the utility model.
Fig. 2 is the utility model overall structure figure.
In figure: 1 motor, 2 pedestals, 3 driven wheels, 4 driven gears, 5 oil connections, 6 bearings, 7 cover plates, 8 bolts.
The specific embodiment
As shown in Figure 1, 2: a kind of rotation type oil well cover, its structure comprises motor, pedestal, driven wheel, driven gear, oil connection, bearing, cover plate, bolt; Motor output shaft connects firmly on driven wheel, and driven wheel and driven gear are positioned in same level, and oil connection is through driven tooth core wheel portion, and oil connection bottom supported by bearing, and a whole set of structure is covered by cover plate, and cover plate is bolted on pedestal; There is the groove that holds driven wheel and driven gear at pedestal middle part, and pedestal integral body is rectangle, and corner location is respectively provided with a bolt hole; Motor is vertically placed, and output shaft is connected by key connected mode with driven wheel; Cylindrical structural is arranged at oil connection bottom, and oil connection is through driven tooth core wheel portion hole, and the mode being connected by key between driven gear and oil connection connects, and flange arrangement is arranged at oil connection top; There is screwed hole at cover plate edge, between cover plate and pedestal, by bolt, is connected.
During use, this device is assembled, actuating motor when crude oil extraction, drives oil connection rotation, makes to keep between sucker rod and oil connection the state of rotation mutually to reduce wearing and tearing.
The above, be only the specific embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of utility model.
