Abstract
The utility model relates to a gear reversing long-stroke oil pumping unit used for mechanical oil extraction in oil fields. The utility model solves the reversing problem of an oil pumping unit by using the principle of an automobile differential mechanism, the differential mechanism and a speed reducer are combined together, and a speed reducer reversing mechanism is formed. A half shaft at one side of the differential mechanism is provided with an output wheel, and a half shaft at the other side is provided with a chuck. The positive and negative rotation of the output wheel can be obtained by alternately stopping or unclamping the chuck. The differential mechanism is a ripe technology; when the differential mechanism is used in a reversing system, the reversing operation is stable, the operation is reliable, the stroke is adjustable, and the service life is long.
Description
The utility model relates to a kind of long stroke pumping unit that does not have the beam type gear wheel reversing.
At present, known long-stroke pumping unit without walking beam has chain type, pitch increased type, broadband type etc.These several oil pumpers adopt motor commutation, the commutation of chain balladeur train, clutch commutation more.The duty of these reversing modes is stable inadequately, breaks down easily, causes to shut down to stop production, and has a strong impact on oil production.In addition, these several reversing arrangement complex structures are not easy to make and maintenance.
The purpose of this utility model provides a kind of reliable operation, commutate steady, easy to maintenance, stroke is adjustable, economical and energy saving, the long stroke pumping unit of long service life.
The purpose of this utility model is achieved in that the operating principle of using vehicle differential mechanism in the changement of oil pumper, and differential mechanism and reductor are combined, and constitutes a deceleration changement.In this mechanism, deceleration part and differential mechanism are partly used gear drive.Their rotation direction is for rotating in opposite directions.A dial is arranged on reducer gear is coaxial, driving lever is arranged on the dish.On the differential mechanism one side semiaxis chuck is arranged also, driving lever and draw-in groove are arranged on the dish.The centre of dial and chuck is the shift fork dish, and there is shift fork the back of dish.On the semiaxis of the differential mechanism other end, be output wheel, wire rope on it or chain, an end connects equilibrate counterweight, and the other end walks around movable pulley and truss top is affixed.In the work, when shift fork blocked chuck on the differential mechanism one side semiaxis, the rope sheave or the sprocket wheel of output clockwise rotated, and movable pulley and lifted weight are raised.When shift fork unclamped chuck, output wheel rotated counterclockwise under the weight effect on the movable pulley.Alternately block or unclamp chuck, just can obtain forward and reverse rotation of output wheel.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is an elevation of the present utility model.
Among Fig. 1, motor rotates by belt pulley 9 driven gears 1, slow down by gear 2 gears 8, again with differential mechanism on gear 5 engagements.Gear 5, gear 8 rotate in opposite directions, and rotation direction is constant all the time.When the shift fork on the shift fork dish 12 blocked chuck 11, output wheel 3 clockwise rotated, and it is up to promote sucker rod 15 by steel cable and movable pulley 14.On the wire rope 13 affixed steel trusss.Driving lever on rotating disk 10 is stirred shift fork dish 12, and shift fork unclamps chuck 11, and output wheel 3 rotates counterclockwise under action of gravity.Chuck 11, rotating disk 10 are alternately stirred shift fork dish 12, and shift fork alternately blocks or unclamps chuck 11, make output wheel 3 positive and negative rotations, just obtain sucker rod 15 and pump.
