Abstract

The utility model relates to a pumping rod button device and consists of a polished rod square clip box, an inner disc, an inner disc insurance pin, spoke glutens, a guard ring, a guard ring insurance pin, a polished rod hole and a polished rod promoting groove, wherein, the polished rod square clip box is welded between the upper and the lower of the inner disc which is in an upper-and-down structure; an upper disc center of the inner disc is the polished rod hole and the guard ring is a symmetrical upper-and-down structure; a plurality of spoke glutens with the symmetrical upper-and-lower structure are provided, and one end of the spoke gluten is welded and connected with an upper edge and a lower edge of the inner disc and the other end is in welded connection with the guard ring; the polished rod hole is taken as a center and the symmetrical upper-and-lower polished rod promoting groove is arranged from the center to a radius edge of the guard ring; the inner disc insurance pin and the guard ring insurance pin are welded on both ends of the polished rod promoting groove in the same plane surface. The safe button operation can be done and the productive effect of oil wells can be improved by opening the guard ring insurance pin and the inside insurance pin in sequence to lead the polished rod to enter the polished rod hole along the polished rod promoting groove, and by closing the inner disc insurance pin and the guard ring insurance pin so as to lead the polished rod square clip to enter the polished rod square clip box.

Description

A kind of sucker rod make-up device

Technical field:

The utility model designs a kind of well rod make-up device, belongs to oil field machinery oil workover tool field.

Background technology:

Oil field machinery oil, rod-pumped well is to be formed by some sucker rod screwed connections, on oil well pump, connect polished rod to oil pumper, because of move up and down load alternation and workover treatment quality problems of oil pumper cause in the pit shaft certain root rod connector to be threaded off, production causes and stops production and economic loss to oil well.When pumping rod disengaging occurring,, reduce a series of losses that cause because of operation in order in time to resume production.Do not go up operation, take manually, revolving force is delivered to the sucker rod place of dropout, reach the purpose of make-up with the pipe wrench polished rod that turns clockwise.Little because of bite polished rod rotating clutch area with pipe wrench, when operating, can only two people operate make-up, the one, strength is not enough, the 2nd, when revolving force transmits downwards because of factors such as pit shaft out of plumb, particularly thread off and be in below the km, produce bigger bounce during make-up, the operator is big because of bounce when the exchange pipe wrench, security incident easily takes place cause personal injury.

Summary of the invention:

The purpose of this utility model is, in order to improve when the sucker rod make-up because of operating inconvenience, and unsafe again instrument defective, it is big to design a kind of occlusal contact area, adapts to many people's operations, produces bigger torsion, and elimination causes the sucker rod make-up device of potential safety hazard because of bounce.

The technical scheme that its technical problem that solves the utility model adopts is: be made up of polished rod side's clamp box, inner disc, inner disc safety plug, spoke muscle, guard ring, guard ring safety plug.Inner disc is a up-down structure, and disk center has the polished rod hole on inner disc, the side's of being clamp box in the middle of the inner disc upper lower burrs, guard ring is symmetrical structure up and down, the spoke muscle is some and is symmetrical structure up and down, the edge welding of one end and inner disc upper lower burrs, the other end and guard ring welding.With the polished rod hole is that the center is to the guard ring radius edge, have laterally zygomorphic polished rod and advance groove, advance same plane, groove two ends at polished rod, be welded with inner disc safety plug and guard ring safety plug, turn clockwise when making this carry out make-up to the dropout sucker rod to mouthpart, it is big to reach occlusal contact area, the purpose of handling safety.

The beneficial effects of the utility model are, can many people operate simultaneously when carrying out the operation of sucker rod make-up, and it is simple in structure, safe and reliable to produce bigger torsion.

Description of drawings:

Below in conjunction with drawings and Examples to this practical further specifying:

Accompanying drawing 1 is the utility model structural representation

Accompanying drawing 2 is the forward vertical cross section of accompanying drawing 1

Among the figure: 1. polished rod side's clamp box, 2. inner disc, 3. inner disc safety plug, 4. spoke muscle, 5. guard ring, 6. guard ring safety plug, 7. polished rod hole, 8. polished rod advances groove, 9. polished rod, 10. polished rod side's clamp.

The specific embodiment

In Fig. 1, inner disc (2) is structure up and down, is welded with polished rod side's clamp box (1) between about the inner disc (2), and the last disk center of inner disc (2) is polished rod hole (7).Guard ring (5) is symmetrical structure up and down.Spoke muscle (4) is symmetrical structure up and down for some, the welding of edge up and down of one end and inner disc (2), the other end and guard ring (5) welding, with polished rod hole (7) is that the center is to guard ring (5) radius edge, have laterally zygomorphic polished rod and advance groove (8), at the two ends of polished rod propelling groove (8), same plane is welded with inner disc safety plug (3) and guard ring safety plug (6).

In Fig. 2, polished rod side's clamp (10) is installed on the polished rod (9), open earlier guard ring safety plug (6) and inner disc safety plug (3) successively, make polished rod (9) advance groove (8) to enter polished rod hole (7) along polished rod, close inner disc safety plug (3) and guard ring safety plug (6) more successively, polished rod side's clamp (10) enters in polished rod side's clamp box (1), can carry out safe make-up operation.

Claims

1. sucker rod make-up device, by polished rod side's clamp box (1), inner disc (2), inner disc safety plug (3), spoke muscle (4), guard ring (5), guard ring safety plug (6), polished rod hole (7), polished rod advances groove (8) to form, it is characterized in that: inner disc (2) is structure up and down, between about the inner disc (2), be welded with polished rod side's clamp box (1), the last disk center of inner disc (2) is polished rod hole (7), guard ring (5) is symmetrical structure up and down, spoke muscle (4) is symmetrical structure up and down for some, the welding of edge up and down of one end and inner disc (2), the other end and guard ring (5) welding, with polished rod hole (7) is that the center is to guard ring (5), radius edge has laterally zygomorphic polished rod and advances groove (8), at the two ends of polished rod propelling groove (8), same plane is welded with inner disc safety plug (3) and guard ring safety plug (6).
