Abstract
The utility model relates to a reinforced sucker rod which mainly solves the problem that the existing sucker rods are prone to be broken below the flange. The utility model is characterized in that a hexagonal prism (3), a reinforced body (4) and a main body (1) are arranged under a boss convex plate (2) in turn; the adjacent parts between the boss (2) and the hexagonal prism (3), between the hexagonal prism (3) and the reinforced body (4) and between the reinforced body (4) and the main body (1) are all in circular arc transition. The reinforced sucker rod has the characteristics of high intensity and difficult break.
Description
Technical field:
The utility model relates to the used sucker rod of oil pumper in the oil recovery field, oil field, especially adds strength sucker rod.
Background technology:
In oil recovery field, oil field, oil pumper is an of paramount importance ingredient during machine is adopted, and sucker rod is the important component part of pumping production.And present sucker rod so just increases the maintenance activity amount because reasons in structure easily from occurring frequent phenomenon of rupture below the flange, needs often to change sucker rod, has shortened the well workover time, has increased cost for oil production, influences the ordinary production of oil well.
The utility model content:
In order to overcome the easily deficiency from rupturing below the flange of existing sucker rod, the utility model provides a kind of strength sucker rod that adds, and this adds strength sucker rod and has the well characteristics of easy fracture not of intensity.
The technical solution of the utility model is: this adds strength sucker rod and comprises sucker rod main body and rod connector boss, be followed successively by hexagonal prism, intensive aspect and main body under the boss, boss and hexagonal prism adjacent, hexagonal prism and intensive aspect adjacent and intensive aspect and main body adjacent are arc transition.
The external diameter of the inscribed circle diameter of the hexagonal prism in the such scheme, the external diameter of intensive aspect and main body successively decreases successively.
The beneficial effect that the utlity model has is: this adds strength sucker rod owing to adopted such scheme, under boss, be followed successively by hexagonal prism, intensive aspect, and their adjacents all are arc transition, reduce stress concentration point, improved anti-fatigue performance, phenomenon of rupture produces thereby eliminate herein, so just reduce the maintenance activity amount, prolong the well workover time, effectively reduced production costs, guaranteed the ordinary production of oil well.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: 1-main body, 2-boss, 3-hexagonal prism, 4-intensive aspect.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this adds strength sucker rod and comprises sucker rod main body 1 and rod connector boss 2, boss is followed successively by hexagonal prism 3, intensive aspect 4 and main body 1 for 2 times, and boss 2 is arc transition with intensive aspect 4 adjacents and intensive aspect 4 with main body 1 adjacent with hexagonal prism 3 adjacents, hexagonal prism 3.The external diameter of the external diameter of the inscribed circle diameter of hexagonal prism 3, intensive aspect 4 and main body 1 successively decreases successively.Owing under boss, be followed successively by hexagonal prism 3, intensive aspect 4, the four bank or ridge and the flanged structure of traditional sucker rod have been changed, adopt hexagonal prism 3 to connect intensive aspect 4 transition portions, be convenient to processing, solved former forging big and heavy stone, easily produce defectives such as forging folding and crackle slightly than big, this structure of the thick intensive aspect of hexagonal prism 3 bottom big and heavy stones makes the stressed zone be extended, strengthen in addition, in case the bar head and the body of rod have the decentraction phenomenon, this structure can effectively be decomposed folding s tress, prolongs fatigue life.And their adjacents all are arc transition, reduce stress concentration point, have improved anti-fatigue performance, and phenomenon of rupture produces thereby eliminate herein, so just reduces the maintenance activity amount, has prolonged the well workover time, effectively reduces production costs, and guarantees the ordinary production of oil well.
Claims (2)
1, a kind of strength sucker rod that adds, comprise sucker rod main body (1) and rod connector boss (2), it is characterized in that: be followed successively by hexagonal prism (3), intensive aspect (4) and main body (1) under the boss (2), boss (2) is arc transition with intensive aspect (4) adjacent and intensive aspect (4) with main body (1) adjacent with hexagonal prism (3) adjacent, hexagonal prism (3).
2, the strength sucker rod that adds according to claim 1 is characterized in that: the external diameter of the inscribed circle diameter of hexagonal prism (3), intensive aspect (4) and the external diameter of main body (1) successively decrease successively.
