Abstract
Provided is a swing rod type non-beam pumping unit. A driving device is arranged on a base seat. One ends of cranks are connected on an output shaft of the driving device, and the other ends of the cranks are provided with idler wheels. The lower ends of swing rods are hinged on the base seat, idler wheel grooves are arranged on the swing rods, and the idler wheels are placed inside the idler wheel grooves. The numbers of the swing rods, the cranks and the idler wheels are two, and the swing rods, the cranks and the idler wheels are symmetrically arranged on two sides of the driving device. A connecting pile is fixed on the swing rods, and a connecting beam is connected on the connecting pile. The lower end of a support is hinged on the base seat, the lower end of a support rod is hinged on the base seat, the upper end of the support rod is hinged on the support, the upper end of the support is provided with a head sheave, and a belt rope is wound on the head sheave. One end of the belt rope is connected on the connecting beam, and the other end of the belt rope is hung on a well opening and connected with a pumping rod. After the head sheave and the belt rope are arranged, a horse head, a walking beam and a connecting rod are of no need, so that the swing rod type non-beam pumping unit is simple in structure, low in manufacturing cost, small in operation mechanism number, little in energy consumption and high in mechanical efficiency, and stroke can be adjusted conveniently.
Description
Technical field
The utility model 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.Such as Chinese patent 109205416.6 " low-energy-consumption oil-pumping ", 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 utility model provides a kind of oscillating rod type blue elephant, makes it simple in structure, low cost of manufacture, and power consumption is few, and mechanical efficiency is high.
The purpose of this utility model is achieved in that and comprises balance weight, fork, drive unit, crank, roller, base, drive unit is installed on the base, one end of crank is connected on the output shaft of drive unit, the other end of crank is installed roller, the fork lower end is articulated on the base, roller groove is arranged on the fork, roller is in the roller groove, fork, crank, roller respectively is two covers and the both sides that are symmetricly set on drive unit, also comprise tie-beam, connect stake, the band rope, head sheave, support, support bar, connecting stake is fixed on the fork, tie-beam is connected to and connects in the stake, the lower end of support is hinged on the base, and the lower end of support bar is hinged on the base, and the upper end of support bar is hinged on the support, head sheave is installed in the upper end of support, the band rope is on head sheave, and an 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 beneficial effects of the utility model are: after being provided with head sheave and band 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 convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the side view after part 2,3 among Fig. 1,4 connects.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model comprises balance weight 1, fork 2, tie-beam 3, connect stake 4, band 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, the other end of crank 9 is installed roller 10, fork 2 lower ends are articulated on the base 11, roller groove 5 is arranged on the fork 2, roller 10 is in 5 li of roller grooves, roller 10 can contact with the two sides of roller groove 5 to produce and roll, connecting stake 4 is fixed on the fork 2, fork 2, crank 9, roller 10 respectively is two covers and the both sides that are symmetricly set on drive unit 3, tie-beam 3 is connected to and connects in the stake 4, the lower end of support 12 is hinged on the base 11, the lower end of support bar 14 is hinged on the base 11, 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, one 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 gradients of center rest 12 and adjusting 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 for adjusting 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 and a side that is connected stake 4 and 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 crank 9 rotations, and the roller 10 on the crank 9 rolls at the side of the roller groove 5 of fork 2, and promotes fork 2 around hinged place, lower end reciprocally swinging, and 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 above-described embodiment, preferred forms of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations, as increasing or reducing the number that connects stake 4, make it can increase or reduce the modulation stroke range.At this, should illustrate, the above-mentioned change of making under inventive concept of the present utility model all will fall in the protection domain of the present utility model.
