Description
Technical Field
The invention relates to a tool, in particular to a hanging height adjuster of a beam hanger of an oil pumping unit.
Background
Currently, a polished rod with the diameter of 28mm or a hollow polished rod with the diameter of 36mm is generally selected for the existing pumping well in the oil field.
When a polished rod with the diameter of 28mm is selected, the distance between the wellhead anti-collision box and the ground is different, when the wellhead anti-collision box is higher than the ground, the lower end of the rope hanger can collide with the wellhead anti-collision box when the lower dead center of a horsehead of the pumping unit is positioned; when the pumping well is under the working condition of alternating load for a long time, the horsehead hair braid can be linearly extended, so that the rope hanger collides with the wellhead anti-collision box.
When selecting hollow polished rod with diameter of 36mm, because the length of the sucker rod short circuit connected to the upper part of the polished rod is limited, the coupling at the lower part of the sucker rod short circuit can also collide with the wellhead anti-collision box.
Under the shortest condition has been selected for use to the horse head hair pigtail, when beam-pumping unit horse head top dead center, the side checkpost on polished rod eye upper portion is close the horse head, and polished rod eye or coupling still bump the well head and prevent bumping the box when the horse head bottom dead center, can't adjust.
All the problems can cause the rapid unloading and the rapid loading when the lower dead point of the horsehead, the rotating connection parts of a horsehead pin, a crank pin, a reduction gearbox gear, a hair braid and the like of the pumping unit are damaged, the abrasion of equipment is increased, the measured data of a load instrument on the upper part of a polished rod eye of the pumping well is inaccurate, the horsehead hair braid is linearly elongated in a fatigue state, the thread of a packing gland of a wellhead anti-collision box is damaged, and the like.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a hanging height adjuster of a beam hanger of an oil pumping unit.
The technical problem of the invention is mainly solved by the following technical scheme:
the utility model provides a beam-pumping unit polished rod eye hangs altitude controller, a serial communication port, beam-pumping unit polished rod eye hang altitude controller contain a cylindric seat body that bears, the up end of bearing the seat body be equipped with one and bear the seat, the lower terminal surface that bears the seat body be equipped with bear the seat once, last bear and be equipped with a cylindric upper portion boss on the seat, bear the seat down and be equipped with a sunken lower part boss, the lateral wall that bears the seat body on be equipped with a bolt hole that runs through, the axial of bearing the seat body on be equipped with a semi-long circular's that runs through open slot, the downthehole bolt that is equipped with of bolt, the end of bolt be equipped with an split pin.
As a better embodiment of the invention, the hanging height adjuster of the beam hanger of the pumping unit is integrally formed by metal.
The hanging height adjuster of the beam hanger of the oil pumping unit has the following advantages: the invention can be repeatedly used for a long time, can quickly and effectively adjust the distance between the rope hanger and the rope cap head, ensures that the rope hanger does not collide with a wellhead anti-collision box, can be installed and taken out only by unloading the pumping unit, and has simple operation and convenient and reliable process. In addition, because the bolt of side can prevent the hair pigtail from following the roll-off in the groove, can reduce the work load of changing the polished rod eye and changing the well head technology, can reduce the time of shutting down the maintenance.
