Abstract

The utility model relates to a sliding balance weight on the oil beam of an oil pumping machine. The sliding balance weight on the oil beam of an oil pumping machine is an auxiliary balance weight. The sliding balance weight on the oil beam of an oil pumping machine can improve the force bearing situations of a motor and the output shaft of an oil pumping machine, and the force bearing situations of the motor and the output shaft of the oil pumping machine are tend to be balanced. The balance weight 3 of a traveling wheel is ridden on the walking beam of the oil pumping machine. Two sides of the balance weight 3 and a connecting rod 5 are connected by an adjustable draw rod 2 in a hinge mode. The sliding balance weight on the oil beam of an oil pumping machine is adopted, the daily power consumption of the oil pumping machine and the torque peak value of a crank shaft can be lowered, the purposes that the system efficiency of the oil pumping machine is enhanced, etc. Are achieved, and thereby, the service life and the effect of the oil pumping machine are enhanced.

Description

Beam well up sliding balance weight

The utility model relates to auxiliary balance weight on the oil-field oil pumper.

At present, the balance weight of beam pumping unit has crank counterbalance on the oil field, and plural equilibrium is heavy, because balance mode is undesirable, makes motor, oil pumper output shaft bear the repetition fluctuating load in the course of the work, influences application life.

The purpose of this utility model is to overcome above-mentioned shortcoming part of the prior art, and provides on a kind of walking beam that helps to improve the oil pumper working condition slide balance heavy.

The purpose of this utility model can reach by the following technical programs: ride the balance weight of road wheel on the walking beam of oil pumper, be connected with the adjustable drawbar hinge between the both sides of balance weight and connecting rod.

Above-mentioned pull bar can disconnect with spending blue nut to connect, and the pull bar two ends are the annular hinge cover, and the annular hinge that wherein is connected with balance weight cover is the concave spherical surface body, and is two body combinations.Balance weight is the shape of a saddle, and there is the spherical linkage axle both sides, has slips to be connected with the pull bar hinge on the connecting rod, slips is to be made of with bolt ［ 7,10 ］ combination two slips sheets, and there is the looping pit of wearing connecting rod 5 at the middle part, be with the hinge sleeve 11 on the pull bar 2 on the bolt 7, and bearing is housed.

The utility model is compared with above-mentioned prior art has following effect: improved the working condition of oil pumper, made oil pumper output shaft torque peak value reduce by 12.6%.Improve pumping unit system efficient 1,36%, day power consumption reduces by 13,8%; This device can be complementary with beam pumping unit, does not change original structure, and is easy for installation.

Fig. 1 is that slide balance weighs 3 installation diagrammatic sketch on the oil pumper walking beam 4;

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

Fig. 3 is Fig. 1 upper slips 1 part section configuration diagram;

Fig. 4 is Fig. 1 upper connecting rod 2 part section configuration diagram;

Fig. 5 is that slide balance weighs 3 part section configuration diagram on Fig. 1.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By shown in Figure 1, on beam pumping unit, ride the balance weight 3 of road wheel 17 on the walking beam 4,5 on balance weight 3 both sides and connecting rod are connected with adjustable drawbar 2 hinges.

Above-mentioned pull bar 2 is for making its adjustable length, disconnects at the middle part with spending blue nut 13 to connect again, and the length of rotating nut 13 compensation linkages is regulated afterwards with nut 12 pretensions on the two ends of spending blue nut 13; There is annular hinge cover ［ 11,14 ］ at the two ends of pull bar 2, and the annular hinge that wherein is connected with balance weight 3 cover 14 is the concave spherical surface body, and is two body combinations, show as Fig. 4, just assemble with balance weight 3 both sides spherical linkage axles 6, with bolt 15 assemblings.Balance weight 3 rides on the walking beam for the shape of a saddle (∏ shape), for ease of sliding on walking beam, the turning cylinder 21 that tape spool holds ［ 19,20 ］ is housed on balance weight and walking beam fitting face, shows as Fig. 5, and the turning cylinder two ends are equipped with wheel 17 usefulness key bodies 18 and are fixed; 22 are bearing glands on Fig. 5 wherein, the 23rd, the axle head pin, outside, balance weight both sides is gone up screw thread spherical linkage axle 6 is installed, with pull bar 2 ends be annular hinge cover 14 assemblings of concave spherical surface body.Slips 1 is arranged on the connecting rod 5, and it is by 8 usefulness bolt ［ 7, the 10 ］ combinations of two slips sheets, and there is the looping pit of wearing connecting rod 5 at the middle part; Bolt 7 can be a part, on it with pull bar 2 on hinge sleeve 11 suits, and bearing 9 is housed, show as Fig. 4.

The utility model is to reach the auxiliary balance purpose like this: prove from our a large amount of in-situ data; Beam pumping unit in whole working cycles process, crank when upstroke (45 °-60 °) and down stroke (245 °～260 °), its crank output shaft torque peak value maximum.By above analysis, our development and design beam pumping unit auxiliary balance mechanism, make oil pumper in the course of the work, when upstroke (45 °～60 °), slide balance heavily slides between oil pumper walking beam fulcrum～tailing axle, crosses the nearly 700(mm of fulcrum) help motor, balance weight is carried out work done.When down stroke (245 °～260 °), slide balance heavily slides between oil pumper fulcrum～horse head, excessively fulcrum 80(mm) carry out storage power outward, realize its auxiliary balance purpose.
