Abstract
The utility model provides a hairless pigtail beam-pumping unit of sucker rod rotary device is equipped with, belongs to petroleum machinery technical field, characterized by: the four-link rod is a parallelogram linkage beam, one end of each of the four-link rod is fixed with a sleeve-shaped polished rod suspension point on the outward extension line end points of the two upper linkage beams, the polished rod suspension point is sleeved into the polished rod, the polished rod is in rotating fit with the polished rod suspension point, the other end of the polished rod is in hinged fit with a limiting wheel which slides up and down in a vertical groove, the limiting wheel is in vertical rolling fit with the vertical groove, the motor is in transmission fit with the rocker arm through a reduction gearbox, and the rocker arm is in hinged fit with the linkage beam at the rear end of the. The beneficial effects are that: because the parallelogram linkage walking beam is adopted, the suspension point is always aligned to the well mouth, a hair braid is cancelled, and the sucker rod rotating device is arranged on the suspension point, so that adverse effects on other parts of the pumping unit are avoided.
Description
Technical Field
The utility model belongs to the technical field of oil machinery.
Background
At present, in order to prevent the sucker rod eccentric wear, more and more of sucker rod rotary device are installed to beam-pumping unit, sucker rod rotary device generally installs at the pigtail lower extreme, replaces the position of polished rod eye, and when sucker rod rotary device during operation, the sucker rod slowly rotates, produces a reverse moment simultaneously, and reverse moment makes two pigtail production position change, makes one of them atress heavier, has shortened the pigtail service life.
Disclosure of Invention
The utility model aims at: the oil pumping machine without hair braid has no hair braid, no horsehead and rope hanger, and the suspension point can always be aligned to the well head without passing through the circular arc of the horsehead and the flexible connection of the hair braid.
The technical scheme of the utility model is that: the four-link rod is a parallelogram linkage beam, one end of each of the four-link rod is fixed with a sleeve-shaped polished rod suspension point on the outward extension line end points of the two upper linkage beams, the perpendicular line of the polished rod suspension point is overlapped with the perpendicular line of the polished rod, the polished rod is sleeved in the polished rod suspension point, the polished rod is in rotating fit with the polished rod suspension point, the other end of the polished rod is in hinged fit with a limiting wheel which slides up and down in a vertical groove, the limiting wheel is in up-and-down rolling fit in a vertical sliding groove, the motor is in transmission fit with the rocker arm through a reduction gearbox, and the rocker arm.
The utility model has the advantages that: because the parallelogram linkage walking beam is adopted, the suspension point is always aligned to the well mouth, a hair braid is cancelled, and the sucker rod rotating device is arranged on the suspension point, so that adverse effects on other parts of the pumping unit are avoided.
Drawings
Fig. 1 is a structural view of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings:
as shown in the figure, 1 is a motor, 2 is a reduction box, 3 is a rocker arm, 4 is a connecting rod, 5 is a parallelogram linkage walking beam, 6 is a limiting structure, 7 is a vertical chute, 8 is a polished rod suspension point, 9 is a well head, 10 is a sucker rod rotating device, and 11 is a polished rod.
When the hairless pigtail pumping unit provided with the sucker rod rotating device works, firstly, the power supply of the motor 1 is switched on, and the rocker arm 3 is rotated through the reduction gearbox 2 after the motor 1 is switched on to operate. The rocker arm 3 rotates to enable the connecting rod 4 to move up and down, the connecting rod 4 moves up and down to drive the parallelogram linkage beam 5 to move, a limiting structure is arranged at one end of the parallelogram linkage beam 5 and comprises a limiting wheel 6 and a vertical sliding groove 7, the limiting wheel 6 can only move up and down in the vertical sliding groove 7, the limiting wheel 6 arranged at one end of the parallelogram linkage beam 5 can only move up and down in the vertical sliding groove 7, so that a polished rod suspension point 8 at the other end of the parallelogram linkage beam 5 provided with the sucker rod rotating device 8 is always aligned with a wellhead 9, and the sucker rod rotating device 10 drives the polished rod 11 to rotate, so that eccentric wear prevention of the sucker rod is realized. The maintenance cost caused by additionally installing the sucker rod rotating device 10 is reduced due to the fact that structures such as hair plaits are omitted.
