Abstract
The utility model relates to a split-type belt device for a belt pumping unit. According to the technical scheme, a left load belt and a right load belt form a load belt; the upper end and the lower end of the left load belt are fixed on a second upper belt plate and a second lower belt plate respectively; the upper end and the lower end of the right load belt are fixed on a first upper belt plate and a first lower belt plate respectively; the upper parts of the first upper belt plate and the second upper belt plate are fixedly connected with the lower end of a connecting piece; the upper end of the connecting piece is connected with a counter weight; the first lower belt plate is connected to the right end of a rope hanger through a first connecting plate; the second lower belt plate is connected with the left end of the rope hanger through a second connecting plate. The split-type belt device for the belt pumping unit has the benefits that an integrated belt is split into two parts through the left load belt and the right load belt; under the condition that the tension of the load belt is sufficient, an exposed space of a polished rod is vacated, and normal production of an oil well is ensured.
Description
Technical field
The utility model relates to a kind of oil extraction in oil field mechanical field, particularly the split type belt dressing of a kind of belt oil pumping machine.
Background technology
Belt oil pumping machine be widely used at present, the one of technology maturation is without beam pumping unit, has the advantages such as reliability is high, obvious energy conservation.Polished rod is for realizing be connected special " sucker rod " between sucker rod and polished rod eye.Because in the topmost of sucker rod, stressed maximum, so the diameter of polished rod is larger than sucker rod diameter, it is high that the rank of steel is wanted, surface is more smooth.But because existing belt oil pumping machine adopts all-in-one-piece belt composition, expose long oil well for polished rod, the situation that there will be polished rod and belt end plate to interfere, affects the normal production of oil well.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provide a kind of belt oil pumping machine split type belt dressing, monolithic belt is divided into two parts, in the situation that ensureing the enough pulling force of load belt, get out of the way the space that polished rod exposes, guarantee the normal production of oil well.
Its technical scheme is: comprise connector, the first epithelium band plate, right load belt, the first hypodermis band plate, the first junction plate, left load belt, the second epithelium band plate, the second hypodermis band plate and the second junction plate, described left load belt and right load belt composition load belt, the two ends up and down of described left load belt are separately fixed on the second epithelium band plate and the second hypodermis band plate, and the two ends up and down of described right load belt are separately fixed on the first epithelium band plate and the first hypodermis band plate; The first described epithelium band plate is fixedly connected with second top of epithelium band plate and the lower end of connector, and the upper end of connector is connected with balancing weight; The first described hypodermis band plate is connected to the right-hand member of polished rod eye by the first junction plate, the second described hypodermis band plate connects the left end of polished rod eye by the second junction plate.
Above-mentioned connector is triangular structure, and bottom is bolted on respectively the second epithelium band plate and the first epithelium band plate, and top is connected with balancing weight by bolt.
The first above-mentioned junction plate and the bottom of the second junction plate are provided with multiple adjustment holes.
The beneficial effects of the utility model are: by left load belt and right load belt, monolithic belt is divided into two parts, and, the two ends up and down of left load belt are separately fixed on the second epithelium band plate and the second hypodermis band plate, the two ends up and down of described right load belt are separately fixed on the first epithelium band plate and the first hypodermis band plate, in the situation that ensureing the enough pulling force of load belt, get out of the way the space that polished rod exposes, guarantee the normal production of oil well.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: connector 1, the first epithelium band plate 2, right load belt 3, the first hypodermis band plate 4, the first junction plate 5, polished rod eye 6, left load belt 7, the second epithelium band plate 8, the second hypodermis band plate 9, the second junction plate 10.
Detailed description of the invention
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises connector 1, the first epithelium band plate 2, right load belt 3, the first hypodermis band plate 4, the first junction plate 5, left load belt 7, the second epithelium band plate 8, the second hypodermis band plate 9 and the second junction plate 10, described left load belt 7 forms load belt with right load belt 3, the two ends up and down of described left load belt 7 are separately fixed on the second epithelium band plate 8 and the second hypodermis band plate 9, and the two ends up and down of described right load belt 3 are separately fixed on the first epithelium band plate 2 and the first hypodermis band plate 4; The first described epithelium band plate 2 and the top of the second epithelium band plate 8 are fixedly connected with the lower end of connector 1, and the upper end of connector 1 is connected with balancing weight; The first described hypodermis band plate 4 is connected to the right-hand member of polished rod eye by the first junction plate 5, the second described hypodermis band plate 9 connects the left end of polished rod eye 6 by the second junction plate 10.
Wherein, connector 1 is triangular structure, and bottom is bolted on respectively the second epithelium band plate 8 and the first epithelium band plate 2, and top is connected with balancing weight by bolt.
In addition, the bottom of the first junction plate 5 and the second junction plate 10 is provided with multiple adjustment holes, is convenient to adjust position.
By left load belt and right load belt, monolithic belt is divided into two parts, and, the two ends up and down of left load belt are separately fixed on the second epithelium band plate and the second hypodermis band plate, the two ends up and down of described right load belt are separately fixed on the first epithelium band plate and the first hypodermis band plate, in the situation that ensureing the enough pulling force of load belt, get out of the way the space that polished rod exposes, guarantee the normal production of oil well.
Do not changing under the prerequisite of existing structure, both ensured the pulling force of load belt, get out of the way again the space that polished rod exposes, and there is versatility, for the oil well of normally producing, if need to improve the situation that polished rod exposes after running into operation, can directly with this device, original load belt structure be replaced, ensure the normal production of oil well.
