Abstract
The utility model provides an auxiliary tool for adjusting a balance block of a beam-pumping unit, comprising a suspension rod, a hinge, screw rods, a threaded sleeve, a steel wire rope and straightening frames, wherein the suspension rod is of a 'T'-shaped structure and a stage is arc-shaped; the lower end is provided with an opening and a hinged hole is arranged in a direction vertical to the opening; one end of each screw rod is flat and is provided with the hinged hole; the other end of each screw rod is a thread; two screw rods are respectively forward and backward outer threads; the threaded sleeve is in a hexagonal structure; two ends of the threaded sleeve are respectively provided with forward and backward inner threads to be matched with the screw rods; each straightening frame is in a rectangular channel steel structure, the width of each straightening frame is slightly larger than the thickness of the balance block and the bottom of each straightening frame is provided with a through hole; the suspension rod and the screw rods are oppositely inserted and are hinged through the hinge; the screw rod at the other end of the threaded sleeve is connected with one end of the steel wire rope; and the other end of the steel wire rope passes through the through holes of the two straightening frames to be connected with the other suspension rod. The auxiliary tool has the advantages of simple structure, convenience for operation, is time-saving and labor-saving; and the balance block is moved to a pre-set position on the ground by using a crank or a crow bar, so as to avoid potential safety hazards, guarantee safety production, reduce well stopping time and increase crude oil yield.
Description
Technical field
The utility model relates to a kind of beam pumping unit balance weight adjustment aid
Background technology
are present; The widely used beam pumping unit balance mode in oil field is that crank balance is promptly installed balance weight on crank; Make that oil pumper motor acting in up-down stroke is identical; Because the oil well production situation constantly changes, also adjustment constantly thereupon of the position of balance weight on the crank.In the scene, what we adopted is that oil pumping machine crank is parked near horizontal level, and balance weight is located at the crank top; Operating personnel climb the enterprising line operate of oil pumping unit reduction gearbox, and personnel stand in the high-altitude safety when guaranteeing to operate of need fastening the safety belt, but do not have suitable position of fastening the safety belt near the reduction box; Safety factor is very low when therefore operating; When particularly adjusting to crank end, because operating position is limited, safety factor is lower.Owing to there is not the position of alternate manner adjustment crankshaft balance weight, operating personnel can only take a risk to operate at present, and the situation generation that has operating personnel to fall down, and labour intensity is big, and the operating time is long, influences crude oil production.
Summary of the invention
The purpose of
the utility model is exactly the above-mentioned defective that exists to prior art, designs a kind of beam pumping unit balance weight adjustment aid.
The utility model is realized by following technical proposals:
the utility model comprises: hanger bar, hinge, screw rod, silk braid, wire rope, centralizing bracket.Its hanger bar is " T " shape structure, and step is curved, and the lower end is provided with opening, is provided with fraising in the direction perpendicular to opening; Screw rod one end is a flat, is provided with fraising, and the other end is a screw thread, and two screw rods are respectively positive and negative external screw thread, and silk braid is outward a hexagonal structure, and two ends are respectively equipped with positive and negative internal thread and cooperate with screw rod; Centralizing bracket is the rectangular slot steel work, and width is slightly larger than the thickness of balance weight, and the bottom is provided with through hole; In balance weight bolts at two ends groove, respectively insert a hanger bar, hanger bar and screw rod are hinged by hinge to inserting, and the other end screw rod of silk braid is connected with wire rope one end, and the wire rope other end passes the through hole of two centralizing brackets, is connected with another hanger bar.
The beneficial effect of
the utility model is: simple in structure; Easy to operate, operating personnel can stand in and utilize crank or crowbar that balance weight is moved on to the precalculated position on the ground, and it is time saving and energy saving to operate; Stop potential safety hazard; Guarantee safe field produces, reduce the adjustment balance weight and stop the well time, increase crude output.

The specific embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
the utility model is made up of hanger bar 1, hinge 2, screw rod 3, silk braid 4, wire rope 5, centralizing bracket 6.Adjustment at first, is parked in level to beam type oil pumping machine crank 7 during balance weight 8, the position that balance weight 8 is downward.Secondly; Insert two " T " shape hanger bar 1 of beam pumping unit balance weight adjustment aid respectively in the two ends set bolt groove of balance weight 8 on the crank 7; A hanger bar 1 is inserted hinged by hinge 2 with 3 pairs of screw rods; The other end screw rod 3 of silk braid 4 is connected with an end of wire rope 5, and the other end of wire rope 5 passes the through hole C of two centralizing brackets 6, is connected with another hanger bar 1.The 3rd, the top that centralizing bracket 6 blocks balance weight 8, adjustment silk braid 4 unloads loose balance weight 8 set bolts with wire rope 5 tensions, utilizes crank or crowbar that balance weight is moved on to the precalculated position.The 4th, tighten balance weight 8 set bolts, remove beam pumping unit balance weight adjustment aid, use with another balance weight 8 of quadrat method adjustment.
