Abstract
Of the present utility model pair of horse head flexible drawing direct drive pumping unit relates to oil production equipment field, be made up of support body, walking beam, horse head and motor, hinged along middle part under the top of its support body and walking beam, the two ends of walking beam are all fixedly connected horse head, the bottom of support body is fixed with directly drives twin-roll and is driven by motor, described horse head lower inside is equipped with movable pulley, ground below the walking beam of support body both sides is provided with fixture, directly drives rope that twin-roll is wound around and is connected with fixture respectively by the movable pulley of side, end.Of the present utility model pair of horse head flexible drawing direct drive pumping unit, structure design is simple, runs smooth, low cost of manufacture, and construction easily, efficient energy-saving, reduces the input of equipment cost simultaneously.
Description
Technical field
The utility model relates to oil production equipment field, particularly relates to two horse head flexible drawing direct drive pumping unit.
Background technology
At present, the oil pumper used in China's oil exploitation is mostly beam pumping unit, and its advantage is that structure is simple, reliable, but it exists the defect that self structure is difficult to overcome.Exactly when horse head runs to upper and lower stop, the corner of crank is zero degree, the equilibrant force of balance weight is minimum, in order to reach peak point with slack flow downstream, motor will export and could realize its running with peak torque, therefore to select when choice of electrical machine the motor that power is larger, can trouble-free operation, the input of the cost that thus consumes energy more greatly, too increases simultaneously.
Utility model content
This practicality is intended to the deficiency for existing in background technology, and the two horse head flexible drawing direct drive pumping units proposed.
Of the present utility model pair of horse head flexible drawing direct drive pumping unit, be made up of support body, walking beam, horse head and motor, hinged along middle part under the top of its support body and walking beam, the two ends of walking beam are all fixedly connected horse head, one end horse head connects polished rod, other end horse head connects balancing weight, the bottom of support body is fixed with directly drives twin-roll and is driven by motor, described horse head lower inside is equipped with movable pulley, ground below the walking beam of support body both sides is provided with fixture, directly drives that the movable pulley of side walked around respectively by the rope that twin-roll is wound around, end is connected with fixture.
As further improvement of the utility model, described two the rope winding directions directly driven on twin-roll are contrary.
As further improvement of the utility model, fixture top is all provided with rope regulating wheel.
As further improvement of the utility model, bottom and the ground conduit of fixture are fixed by screw rod.
Of the present utility model pair of horse head flexible drawing direct drive pumping unit, structure design is simple, run smooth, low cost of manufacture, construction easily, adopt two horse head balance, steel cable flexible draws, utilize movable pulley to move and reduce Motor torque, energy conservation, overcomes existing beam pumping unit when horse head runs to upper and lower stop, the corner position zero degree of crank, the equilibrant force of balance weight is minimum, motor will export and could realize its running with peak torque, and consume energy higher problem, efficient energy-saving, reduces the input of equipment cost simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing 1 to of the present utility model pair of horse head flexible drawing direct drive pumping unit, be described further.
Of the present utility model pair of horse head flexible drawing direct drive pumping unit, by support body 1, walking beam 2, horse head 3 and motor 4 are formed, the top of its support body 1 and walking beam 2 times hinged along middle part, the two ends of walking beam 2 are all fixedly connected horse head 3, one end horse head 3 wire rope connects polished rod 11, other end horse head 3 connects balancing weight 12, the bottom of support body 1 is fixed with directly drives twin-roll 5, and driven by motor 4, bottom inside described two ends horse head 3 is equipped with movable pulley 6, ground below support body 1 both sides walking beam 2 is provided with fixture 7, directly drive the movable pulley 6 that corresponding side walked around respectively by the rope 8 that twin-roll 5 is wound around, end is connected with fixture 7.Described two the rope winding directions directly driven on twin-roll 5 are contrary.Fixture 7 top is all provided with rope regulating wheel 9.Bottom and the ground conduit 10 of fixture 7 are fixed by screw rod, and the direction of conduit 10 is consistent with the direction of walking beam 2, fixture 7 can in conduit 10 transverse shifting, to be fixed on optimum position.
Of the present utility model pair of horse head flexible drawing direct drive pumping unit, motor can rotate and reverse and hocket, and then directly drives wire rope twin-roll, and jig frequency is stepless adjustable.Rope 8 adopts wire rope, and wirerope-winding method is the wire rope namely stretching to two horse heads is being contrary with the winding direction directly driving twin-roll 5.
The utility model adopts two this mode of horse head flexible drawing direct drive pumping unit just can reduce the power of motor, works under can reaching identical load equally.
