Description
Technical Field
The utility model relates to a beam-pumping unit technical field especially relates to an adjustable beam-pumping unit horse head round pin.
Background
The beam-pumping unit is the most common pumping unit at present, and the connection mode of the horsehead and the walking beam is generally divided into three modes of side rotation, detachable type and upturning type. The side rotation type oil well is the most common mode, two horsehead pin holes are respectively welded on two sides of a walking beam and a horsehead, the horsehead and the walking beam are connected together by inserting the horsehead pins, when an oil well needs to operate, the two horsehead pins on one side are pulled out, the horsehead can be rotated laterally to enable the horsehead to leave out an operation space, and oil pipes can be conveniently lifted and lowered. The horse head round pin axle of traditional beam-pumping unit is the whole cylindric hinge axle of making by 45 # steel, because under the effect of heavy load of reversal for a long time, wearing and tearing grow easily appears in horse head and the empty donkey head round pin, makes walking beam and donkey head reciprocate in-process shell pinhole dislocation relatively, causes complete machine vibration and donkey head atress uneven, easily leads to the donkey head to appear the damage accident, this kind of structure of donkey head round pin makes the maintenance work degree of difficulty big to the effect is very unsatisfactory.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the not enough adjustable beam-pumping unit horse head round pin that exists to above-mentioned prior art is provided to a simple structure, loading and unloading convenience, safe and reliable.
The utility model discloses the technical scheme who adopts does: the utility model provides an adjustable beam-pumping unit horse head round pin which characterized in that: including outer taper sleeve, interior cone, locking mechanism, the inner wall of outer taper sleeve is equipped with certain tapering, is equipped with the axial opening who link up tip from top to bottom on its lateral wall, the interior cone stretches into from the lower tip of outer taper sleeve to wear out the back from the upper end of interior cone, the tapering through the interior cone makes the external diameter of outer taper sleeve constantly expand, installs locking mechanism at the upper end of interior cone, locks the interior cone on outer taper sleeve through locking mechanism.
According to the technical scheme, the locking mechanism comprises a locking piece and a force application part, wherein the locking piece and the force application part are detachably connected with the upper end part of the inner cone.
According to the technical scheme, the locking member is a locking cap, the force application component is a pull rod, and the pull rod is fixedly installed in a radial through hole formed in the end portion of the locking cap.
According to the technical scheme, the lower end part of the locking cap is provided with an outward-turned radial flange, and the outer diameter of the radial flange is larger than the inner diameter of the upper end part of the outer cone sleeve.
According to the technical scheme, the lower end part of the inner cone is provided with an annular groove, the outer cone sleeve is provided with an anti-withdrawal pin, and the anti-withdrawal pin is arranged with the annular groove.
According to the technical scheme, the lower end part of the inner cone is of a cone-shaped structure, the outer diameter of the inner cone is gradually increased from bottom to top, and the outer diameter of the middle upper part of the inner cone matched with the outer taper sleeve is gradually decreased from bottom to top.
According to the technical scheme, the locking cap is connected with the inner cone through threads.
The utility model discloses the beneficial effect who gains does:
the utility model has simple structure, can avoid the whole machine vibration caused by the loose of the bolt of the horse head, and reduce the damage to the oil pumping machine and the influence on the rod pump; the horse head pin takes out the convenience, beat inner cone tip from up down with the hammer during installation and strut outer taper sleeve, through ear hole locking walking beam and horse head, make it not take place relative displacement in work, avoid appearing the sound of being banned, cause the complete machine to vibrate, during the dismantlement, dismantle the locking cap, beat the inner cone downwards, make the inner cone move down and relieve the stress of outer taper sleeve, recover outer taper sleeve, thereby can make whole horse head pin easily take out, the loading and unloading is convenient, safety and reliability, whole pin can not rust to die in the ear hole, further improve the efficiency of construction.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-3, this embodiment provides an adjustable horse head pin for pumping unit, including outer taper sleeve 1, interior cone 2, locking mechanism, the inner wall of outer taper sleeve 1 is equipped with certain tapering, is equipped with the axial opening who link up upper and lower tip on its lateral wall, interior cone 2 stretches into from the lower tip of outer taper sleeve 1 to wear out the back from the upper end of interior cone 2, the tapering through interior cone 2 makes the external diameter of outer taper sleeve 1 constantly expand, installs locking mechanism at the upper end of interior cone 2, locks interior cone 2 on outer taper sleeve 1 through locking mechanism.
In this embodiment, the locking mechanism includes a locking member and a force applying member detachably connected to the upper end of the inner cone 2. Specifically, the retaining member is a locking cap 3, and the locking cap 3 is connected with the inner cone 2 through threads. The force application component is a pull rod 4, and the pull rod 4 is fixedly installed in a radial through hole formed in the end portion of the locking cap 3. The lower end part of the locking cap 3 is provided with an outward-turned radial flange, and the outer diameter of the radial flange is larger than the inner diameter of the upper end part of the outer taper sleeve 1.
In this embodiment, an annular groove is formed at the lower end of the inner cone 2, and an anti-retreat pin (not shown) is disposed on the outer cone sleeve 1, and the anti-retreat pin is disposed in the annular groove 5.
The lower tip of interior cone 2 is the taper structure, and its external diameter from the bottom up grow gradually, the external diameter from the bottom up of interior cone 2 and outer taper sleeve 1 matched with well upper portion diminishes gradually, its simple structure, the processing of being convenient for.
This device dress during the use is in the earhole of walking beam and horse head, and outer taper sleeve 1 is sat on the earhole, beats outer taper sleeve 1 and struts with the hammer from up knocking inner cone 2 tip down, through earhole locking walking beam and horse head, makes it not take place relative displacement in work, avoids appearing bang, bang sound causes the complete machine to vibrate. When the locking cap 3 is detached, the inner cone 2 is knocked downwards, the inner cone 2 moves downwards to relieve the stress of the outer cone sleeve 1, the outer cone sleeve 1 is restored, and therefore the whole horse head pin can be taken out easily.
