Abstract
The utility model relates to a high-intensity laterally-inserted dropping-preventing anti-torsion sucker rod which belongs to the oil extraction equipment field of oil machinery. The utility model consists of the body of the dropping-preventing anti-torsion sucker rod, a spare nut, a spring gasket, a screw thread hoop cover and a coupling. The upper end of the dropping-preventing anti-torsion sucker rod is provided with an inversed wedge joint , a circular bead and a wrench; the lower end is provided with a screw thread and an inversed wedge joint. The spare nut with inside screw thread and the screw thread hoop cover are arranged at the lower end of the body of the dropping-preventing anti-torsion sucker rod. The spring gasket is arranged between the spare nut and the screw thread hoop cover. Inversed concave wedge grooves are arranged at two ends of the coupling. The inversed concave wedge groove at the upper end of the coupling is laterally inserted and cooperated with the inversed wedge joint at the lower end of the dropping-preventing anti-torsion sucker rod. The screw thread hoop cover obstructs the inversed concave wedge groove at the upper end of the coupling in the screw thread hoop cover, namely forming a simple-root high-intensity lateral-inserted dropping-preventing anti-torsion sucker rod. According to requirements, a plurality of simple-root high-intensity lateral-inserted dropping-preventing anti-torsion sucker rods can be connected to a rod string. The sucker rod has the advantages of super-high intensity of dropping-preventing and anti-torsion performances, easy assembly and convenient installation.
Description
Affiliated technical field
The antitorque sucker rod of a kind of superhigh intensity side-plug-in anti-avulsion belongs to petroleum machinery oil production equipment field.
Background technology
The sucker rod that is applied to the drive screw pump sump at present generally adopts common sucker rod and tapered shaft head, fan-shaped bar head sucker rod.Common sucker rod generally is applied to the pumping production well and moves reciprocatingly because of it connects for straight thread, is applied to screw bolt well and recovers the oil, and its anti-twisting property is not enough.Tapered shaft head, fan-shaped bar head sucker rod all can cause with the connecting portion of this rod collar looseningly in screw bolt well body of rod rotary work, cause the dropout accident, so that influence the normal oil producing operation of screw pump.
Summary of the invention
Be applied to the deficiency that drive screw pump sump sucker rod anti-twisting property is not enough and connecting portion is easily loosening at present in order to overcome, the utility model provides a kind of superhigh intensity side-plug-in anti-avulsion antitorque sucker rod, the antitorque sucker rod of this superhigh intensity side-plug-in anti-avulsion not only has superhigh intensity anti-avulsion, torsional property, and has assembling characteristics simple, easy for installation.
The technical scheme that its technical problem that solves the utility model adopts is: the antitorque sucker rod of a kind of superhigh intensity side-plug-in anti-avulsion by the antitorque sucker rod body of rod of anti-avulsion, be equipped with mother, spring washer, screw thread hoop cover, box cupling and form.The antitorque sucker rod body of rod of anti-avulsion upper end has down protruding wedge joint, shoulder and spanner side, the lower end is threaded and falls protruding wedge joint, earlier the female fully and screw thread hoop cover that has internal thread is sleeved on the antitorque sucker rod body of rod of anti-avulsion lower end, spring washer is contained in and is equipped with between mother and the screw thread hoop cover, the box cupling two ends have down recessed wedge-shaped slot, the protruding wedge joint side inserting of falling of recessed wedge-shaped slot and the antitorque sucker rod body of rod of anti-avulsion lower end of falling of box cupling upper end is closed, rotate screw thread hoop cover then the recessed wedge-shaped slot that falls of box cupling upper end is kept off in the hoop cover, promptly constitute the antitorque sucker rod of single superhigh intensity side-plug-in anti-avulsion; During following well operations, the box cupling lower end of the antitorque sucker rod of single superhigh intensity side-plug-in anti-avulsion is fallen the protruding wedge joint side inserting of falling of recessed wedge-shaped slot and the antitorque sucker rod body of rod of the anti-avulsion of the following antitorque sucker rod of another root superhigh intensity side-plug-in anti-avulsion upper end and is closed and be connected, then screw thread hoop cover is tightened, the recessed wedge-shaped slot of falling of box cupling lower end is kept off in the hoop cover, the circular bead surface of the antitorque sucker rod body of rod of the anti-avulsion of the lower surface of screw thread hoop cover and the following antitorque sucker rod of superhigh intensity side-plug-in anti-avulsion upper end holds out against, tighten being equipped with mother at last, the many antitorque sucker rods of single superhigh intensity side-plug-in anti-avulsion can be in turn connected into rod string according to demand.
The rod string that connects is owing to adopt the protruding wedge joint side inserting of falling of the recessed wedge-shaped slot and the antitorque sucker rod body of rod of anti-avulsion of falling at box cupling two ends to close and be formed by connecting, the outside has screw thread hoop cover that the recessed wedge-shaped slot cooperation of falling of box cupling two ends is blocked, there is the mother of being equipped with to be equipped with screw thread hoop cover tight, form with dual fail-safe, improve the anti-twisting property of screw bolt well rod string, solved the dropout problem of screw bolt well rod string.
