Description

Guiding distance increasing unit wheel type oil pumping unit

Technical field

The utility model belongs to oil exploration equipment, is specifically related to a kind of guiding distance increasing unit wheel type oil pumping unit.

Background technology

The oil pumper major part of field use is a beam pumping unit at present.But shortcomings such as energy transfer efficiency is low, the motor power utilization rate is low, stroke can not increase substantially that this oil pumper exists.Also has a kind of orthoscopic oil pumper, though can raise the efficiency and increase stroke, its complex structure, the manufacturing difficulty of processing is big, and difficulty is installed, and especially chain extends because of wearing and tearing and produces vibration and swing, part easily is damaged, and reliability is low, and maintenance is inconvenient uneconomical.Therefore, need a kind of simple in structure, substitute products that efficient is high.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned defective that has oil pumper now, proposes a kind of guiding distance increasing unit wheel type oil pumping unit.

The purpose of this utility model is achieved through the following technical solutions.

Guiding distance increasing unit wheel type oil pumping unit comprises frame, large pulley, crank, connecting rod, guiding distance increasing unit, driver part, idle self-oiling device, pull rope, sucker rod, counterweight, motor, electrical control cubicles, well workover shift unit; Described large pulley and driver part are installed in upper rack coaxially, connecting rod connecting crank and large pulley; On the output shaft separately that is contained in driver part respectively of crank and boosting guiding distance increasing unit, being subjected to derive is contained on the large pulley to distance increasing unit accordingly; Pull rope is contained in by direction separately respectively or connects polished rod eye and counterweight around large pulley and large pulley both sides, and polished rod eye connects sucker rod; Band stop motor connects driver part; The gear of well workover shift unit is contained in large pulley main shaft both sides, and the tooth bar that is complementary is contained on the frame.

The utility model has the advantages that: under the effect of guiding distance increasing unit, can continue to do rotation in the same way when large pulley rotates to bottom dead centre, stroke doubles like this, adopts the symmetrical expression balance, static balancing precision height.Compare with existing oil pumper, the utlity model has simple in structure, durable advantage, the utility model is energy-efficient, safe and reliable, and need not keep in repair for a long time, only need do time-based maintenance.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is a guiding distance increasing unit structural representation of the present utility model.

Among the figure: 1 frame, 2 large pulleys, 3 cranks, 4 connecting rods, 5 boostings guiding distance increasing unit, 6 are subjected to derive to distance increasing unit 7 rear output shafts, 8 front output shafts, 9 pull ropes, 10 pull ropes, 11 driver parts, 12 motors, 13 counterweights, 14 idle self-oiling devices, 15 left gears, 16 left tooth bars, 17 sucker rods, 18 polished rod eyes, 19 gear wheels, 20 electrical control cubicles, 21 belt pulleys, 22 main shafts, 23 right gears, 24 right tooth bars.

The specific embodiment

With reference to Fig. 1, Fig. 2, shown in Figure 3, large pulley 2 and driver part 11 coaxial frame 1 tops that are arranged on; Connecting rod 4 connecting cranks 3 and large pulley 2, driver part 11 comprises: belt pulley 21, gear wheel 19, rear output shaft 7, front output shaft 8, idle self-oiling device 14; Described guiding distance increasing unit is formed by two halves are corresponding, and promptly half is contained on the output shaft of driver part 11 for boosting guiding distance increasing unit 5; Second half is derived to distance increasing unit 6 for being subjected to, and is contained on the large pulley 2.Crank 3 and boosting guiding distance increasing unit 5 are contained in respectively on the rear output shaft 7 and front output shaft 8 of driver part 11 outputs, derived and be and boosting guiding distance increasing unit 5 corresponding being contained on the large pulley 2 that are contained on the rear output shaft 8 to distance increasing unit 6,

pull rope

9 and 10 is contained in by direction separately respectively or connects polished rod eye 18 and counterweight 13 around large pulley 2 and large pulley 2 both sides, polished rod eye 18 connects sucker rod 17, according to the radical of oil pumper size decision pull rope.Idle self-oiling device 14 is arranged on the gear wheel 19 in the driver part 11.Motor 12 is contained in frame 1 top, by electrical control cubicles 20 controls; Motor 12 connects the belt pulley 21 of driver part 11 and rotates boosting guiding distance increasing unit 5 and crank 3, drives large pulley 2 rotations by connecting rod 4.In crank 3 and large pulley 2 both circle footpaths not under the effect of equal difference, when rotating to top dead-centre, crank 3 transmission large pulleys 2 do automatic reverse, and boosting guiding distance increasing unit 5 and be subjected to derive corresponding when large pulley 2 rotates to bottom dead centre to distance increasing unit 6 two halves, it is that large pulley 2 is done to continue in the same way to rotate that boosting guiding distance increasing unit 5 promotes to be subjected to derive to distance increasing unit 6.The left gear 15 of well workover shift unit and right gear 23 are contained in main shaft 22 both sides of large pulley 2, and left tooth bar 16 that is complementary and right tooth bar 24 are contained on the frame 1, and during well workover, gear that will be complementary and tooth bar engagement are thrown off during normal operation.
