Description
Technical field
The present invention is the pumping unit that the oil field is used, and is a kind of oscillating rod type blue elephant.
Background technology
Present oil pumper kind is more, all comes with some shortcomings, and subject matter is that mechanism is complicated, and parts are many, and the running link is many, and mechanical efficiency is low.Like Chinese patent 109205416.6 " low energy consumption oil pumper ", be a kind of beam pumping unit, horse head, walking beam, connecting rod are arranged, thereby complex structure, manufacturing cost is high, big energy-consuming, and mechanical efficiency is low.
Summary of the invention
The purpose of this invention is to provide a kind of oscillating rod type blue elephant, make it simple in structure, low cost of manufacture, power consumption is few, and mechanical efficiency is high.
The objective of the invention is to realize like this: comprise balance weight, fork, drive unit, crank, roller, base, drive unit is installed on the base, and an end of crank is connected on the output shaft of drive unit; The other end of crank is installed roller, and the fork lower end is articulated on the base, and roller groove is arranged on the fork; Roller is in the roller groove, and fork, crank, roller respectively are two covers and the both sides that are symmetricly set on drive unit, also comprises tie-beam, connects stake, is with rope, head sheave, support, support bar; Connect stake and be fixed on the fork, tie-beam is connected and connects in the stake, and the lower end of support is hinged on the base; The lower end of support bar is hinged on the base; The upper end of support bar is hinged on the support, and head sheave is installed in the upper end of support, and the band rope is on head sheave; One end of band rope is connected on the tie-beam, and the other end of band rope falls in well head and is connected with sucker rod.
Connection stake on the fork has 1-6.
Balance weight is fixed on the fork.
The invention has the beneficial effects as follows: after being provided with head sheave and being with rope, do not need horse head, walking beam, connecting rod, thus simple in structure, low cost of manufacture, works is few, and power consumption is few, and mechanical efficiency is high, and the modulation stroke is conveniently.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the side view after part 2,3,4 connects among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described.
Can be known that by figure embodiments of the invention comprise balance weight 1, fork 2, tie-beam 3, connect stake 4, are with rope 6, head sheave 7, drive unit 8, crank 9, roller 10, base 11, support 12, support bar 14, drive unit 8 is installed on the base 11; One end of crank 9 is connected on the output shaft of drive unit 8, and the other end of crank 9 is installed roller 10, and fork 2 lower ends are articulated on the base 11; Roller groove 5 is arranged on the fork 2, and roller 10 is in 5 li of roller grooves, and roller 10 can contact with the two sides of roller groove 5 to produce and roll; Connect stake 4 and be fixed on the fork 2, fork 2, crank 9, roller 10 respectively are two covers and the both sides that are symmetricly set on drive unit 3, and tie-beam 3 is connected and connects in the stake 4; The lower end of support 12 is hinged on the base 11, and the lower end of support bar 14 is hinged on the base 11, and the upper end of support bar 14 is hinged on the support 12; Head sheave 7 is installed in the upper end of support 12; Band rope 6 is on head sheave 7, and an end of band rope 6 is connected on the tie-beam 3, and the other end of band rope 6 falls in well head and is connected with sucker rod.The effect of support bar 14 is center rest 12 and the gradient of regulating support 12, so that head sheave 7 is left pithead position, is convenient to job execution.Connection stake 4 on the fork 2 has 1-6, is used to adjust the stroke of oil pumper, and tie-beam 3 changes are connected with another when stake 4 connects just can change length of stroke.Balance weight 1 is fixed on the fork 2, balance weight 1 be connected the side that stake 4 respectively is in fork 2.
On the support bar 14 adjusting device is arranged, rotation adjustment device can make support bar 14 flexible, thus the gradient of regulating support 12.
During work, drive unit 8 drives cranks 9 rotations, and the roller 10 on the crank 9 rolls on the side of the roller groove 5 of fork 2, and promote fork 2 around the hinged place, lower end reciprocally swinging, 6 walkings of pulling band rope make the sucker rod that is connected on the band rope 6 move back and forth oil pumping.
In the foregoing description, preferred forms of the present invention is described, obviously, under inventive concept of the present invention, still can be made a lot of variations,, make it can increase or reduce the modulation stroke range as increasing or reducing the number that connects stake 4.At this, should explain that the above-mentioned change of under inventive concept of the present invention, being made all will fall in protection scope of the present invention.
