Abstract
The utility model relates to attached devices for a pumping machine and particularly relates to an eccentric wear resistant device for a pumping rod of the pumping machine. The eccentric wear resistant device comprises the pumping machine and the pumping rod connected with the pumping machine, wherein the pumping machine is connected with the pumping rod through a ball head; a load reduction device is arranged on the pumping rod; a stepping rotating mechanism of the pumping rod is arranged in the load reduction device; the stepping rotating mechanism comprises a rotating fluted disc fixedly connected with one end of the pumping rod, fixed teeth I fixed on the side walls of the load reduction device, and fixed teeth II fixed at the bottom of the load reduction device; teeth are arranged on both the lower surface and the upper surface of the fluted disc; the tooth grooves in the upper part and the lower part of the rotating fluted disc are staggered mutually. The eccentric wear resistant device adopts a pure mechanical structure, the reliability is high, electric power and other power used in an oil field are reduced, and the eccentric wear resistant device has the advantages that the safety and durability are achieved, and the cost is reduced.
Description
Technical field
The utility model relates to oil pumper accessory device, specifically the anti-eccentric wearing device of a kind of beam-pumping unit sucker rod.
Background technology
At present, due to oil pumping in oil fields bar oil pumping the course of work in owing to being subject to the condition restriction such as manufacture, installation, the concentrated wear of oil well oil-out and sucker rod circumference is very serious, sucker rod length 1～more than 3,000 meter.Sucker rod and flowline have the part friction of nearly ten thousand times every day, and sucker rod is is sharply worn and torn.So just greatly shortened the life-span of sucker rod.In the patent document that is 201120461403.8 in the patent No., provide anti-bias the wearing away of a kind of beam-pumping unit sucker rod to carry apparatus, adopt magnetic devices to drive the worm screw action in worm-and-wheel gear, thereby worm screw drives worm gear, worm gear to drive sucker rod to rotate, complete the technique effect that sucker rod concentrated wear becomes even circumferential wearing and tearing, worm screw is rotated and drives worm gear to rotate, worm gear rotates and drives sucker rod to rotate, so just make concentrated wear become the uniform wear of circumference, thereby improve the application life of sucker rod.But, although the requirement that the restriction in the place using at oil pumper can not electricity consumption can solve,, owing to being irony part on equipment, magnetic conductivity is very strong, strong magnet uses therein for a long time, easily, by equipment magnetization, produces serious side effect, and larger for the effect of magnetic influence of magnet, demagnetization is fast, and after demagnetization, equipment can not run well, therefore its security reliability deficiency.
Summary of the invention
The purpose of this utility model, is exactly the problem existing for solving prior art, and has designed the anti-eccentric wearing device of a kind of beam-pumping unit sucker rod, adopts pure frame for movement to complete the rotation of sucker rod, increases the abrasion resistance of sucker rod.
The technical solution of the utility model is: the anti-eccentric wearing device of a kind of beam-pumping unit sucker rod, it comprises oil pumper and the sucker rod being attached thereto, oil pumper is connected with sucker rod by bulb, and sucker rod is provided with load reducer, and described load reducer inside is provided with sucker rod stepping rotating mechanism; Stepping rotating mechanism comprises the rotary fluted disc that is fixedly connected with sucker rod one end, be fixed on fixed teeth I on load reducer sidewall and the fixed teeth II of load reducer bottom; The upper and lower surface of described fluted disc all has tooth, the upper and lower teeth groove mutual dislocation of described rotary fluted disc.
In order to realize stepping effect accurately, the upper tooth on described fluted disc and lower tooth are unequal-side tooth, and two flank of tooth length ratios of described tooth are 1:2.
To stop described sucker rod and load reducer bottom and be provided with wiper of rubber in order to put.
The beneficial effects of the utility model can draw by such scheme: because the anti-eccentric wear technology of oil pumping in oil fields bar is mainly to pass through gear drive, the sucker rod making is in the vertical direction when straight reciprocating motion, in the additional rotation that speed is very slow of circumferencial direction.Adopt such measure just the concentrated wear of sucker rod circumference to be become to the uniform wear of sucker rod circumference, the sucker rod life-span making extends greatly.The advantages such as the utility model adopts pure frame for movement, and reliability is high, has reduced the use of electric power and other power in oil field, has safety durable, cost-saving.
As can be seen here, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of rotary fluted disc.
Wherein, 1 is load reducer, and 2 is fluted disc, and 3 is fixed teeth I, and 4 is fixed teeth II, and 5 is sucker rod.
detailed description of the invention:
In order to understand better the utility model, explain in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Detailed description of the invention: as shown in Figure 1, the anti-eccentric wearing device of a kind of beam-pumping unit sucker rod, it comprises oil pumper and the sucker rod being attached thereto, oil pumper is connected with sucker rod by bulb, sucker rod is provided with load reducer 1, and described load reducer 1 inside is provided with sucker rod 5 stepping rotating mechanisms; Stepping rotating mechanism comprises the rotary fluted disc 2 that is fixedly connected with sucker rod 5 one end, be fixed on fixed teeth I 3 on load reducer 1 sidewall and the fixed teeth II 4 of load reducer bottom.Be provided with wiper of rubber at sucker rod and load reducer bottom.
As shown in Figure 2, the upper and lower surface of described fluted disc 2 all has tooth, the upper and lower teeth groove mutual dislocation of fluted disc 2.Upper tooth on fluted disc 2 and lower tooth are unequal-side tooth, and two flank of tooth length ratios of described tooth are 1:2.
Above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
