Abstract
The utility model relates to a special tool for exchanging a pumping well head packing. The special tool is provided with a pry bar which is provided with a spiral groove on the lower portion. The spiral groove is in an anticlockwise spiral structure, the spiral groove and the pry bar axis form an angle of 45 degrees, a wedge-shaped pointed end is arranged at the lower end of the pry bar, and a stress applying component is arranged at the upper end of the pry bar. When the tool is used, rapid exchanging of the pumping well head packing can be achieved, labor intensity is reduced, and working efficiency is improved. The tool is not only applicable to exchange a low-pressure packing, but also a high-pressure packing; and the tool has the advantages of being convenient to operate, not easy to damage, time saving, labor saving, wide in applicable range and the like.
Description
Technical field
The utility model belongs to well recovery maintenance of equipment instrument technical field, is that a kind of mouth of pumped oil well is changed the packing special tool.
Background technology
At present, recover the oil and generally to adopt oil pumper suspension sucker rod to carry out extraction in the oil field, and the well head position need install the rubber packing additional and cooperate with polished rod and seal.In the extraction process,, often need to change the high and low pressure packing in the packing box owing to wear and tear.No matter be often to adopt rod-pumped well or thermal recovery rod-pumped well, when changing packing, all need use suitable tools that packing is changed,, avoid contaminated environment to guarantee the good seal of packing.Generally use a flat mouthful bottle opener to change the packing operation at present because the long 160mm of high and low pressure packing box, internal diameter 60mm, use flat mouthful bottle opener can be comparatively like a cork with in the packing box, the packing on top draws out, but for the packing of bottom, operation is very inconvenient.Bottle opener is drawn when getting the top packing, and the bottle opener head inserts in the packing otch, utilizes the packing lower cut as fulcrum, packing is positioned at more than the bottle opener head partly lever up, and rotates bottle opener counterclockwise, just can be successively with in the packing box, the top packing draws out.When drawing the bottom packing, after bottle opener inserts the packing otch, in packing box with the packing end face almost in vertical state, do not have fulcrum, bottle opener does not have too big effect.Like this, not only waste time and energy, and after changing the packing of a bite oil well often, the screwdriver rod bending becomes arc, cause bottle opener damage.
The utility model content
The purpose of the utility model is to provide a kind of quick replacing that can realize the production wellhead packing, reduces labor intensity, and improves operating efficiency, and mouth of pumped oil well easy to use is changed the packing special tool.
Realize that the technical scheme that above-mentioned purpose is taked is: a kind of mouth of pumped oil well is changed the packing special tool; Have a bottom and have the spiral fluted ripping bar; Said helicla flute is counterclockwise spiral; The angle of helicla flute and ripping bar axis is 45 °, is provided with the wedge-like tip in the lower end of ripping bar, and the upper end of ripping bar is provided with afterburning assembly.
Said afterburning assembly has a body, and the outer circumferential sides of body is hinged with the afterburning handgrip that symmetry is put through connecting bearing with pin, and the contact jaw of afterburning handgrip and body is the inclined-plane, and the lower end and the ripping bar of body are welded to connect.
Rolling has anti-skidding reticulate pattern or is set with the anti-slip rubber cover on the said afterburning handgrip.
Mouth of pumped oil well according to such scheme is processed is changed the packing special tool; Straight bar section through ripping bar; Guaranteed that this instrument can be lowered to the packing box bottom, the high pressure-conducting disk root of bottom changed that screw rod has guaranteed that partly this instrument can get into packing smoothly and be 45 ° and the counterclockwise otch that cuts.Under the effect of afterburning assembly, promote afterburning handgrip counterclockwise, in rotating process, the packing on the packing jacking top of bottom, the packing of drawing out is ejected packing box smoothly along the hand of spiral.Afterburning assembly can play the effect that increases moment, can alleviate labor strength.This special tool is not only applicable to the replacing of low pressure packing, is equally applicable to the replacing of high pressure-conducting disk root, changes packing with the flat mouthful bottle opener of the employing of routine and compares, and this instrument uses easy to operate, not fragile, saves time, and is laborsaving, applied widely.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to Fig. 1, the mouth of pumped oil well of the utility model is changed the packing special tool, has the ripping bar 1 that a bottom has helicla flute 1-1; Said helicla flute 1-1 is counterclockwise spiral, and the angle of helicla flute 1-1 and ripping bar 1 axis is 45 °, and the lower end of ripping bar 1 is provided with wedge-like tip 1-2; The upper end of ripping bar 1 is welded with afterburning assembly, and this reinforcing assembly has a body 2, and body 2 is welded to connect with ripping bar 1; The outer circumferential sides of body 2 is welded with upper and lower connection bearing 4,6; Connect bearing 4,6 up and down and 3 be hinged with the afterburning handgrip 5 that symmetry is put through pinning, rolling has anti-skidding reticulate pattern or is set with the anti-slip rubber cover on afterburning handgrip 5, anti-skidding when being used for reinforcing.Afterburning handgrip 5 is set to the inclined-plane with the contact jaw of body 2, can adjust the direction of rotation of afterburning handgrip 5.This instrument can guarantee that the straight bar section of ripping bar 1 is lowered to the packing box bottom, and the packing of bottom is changed, and the spiral angle of helicla flute 1-1 part is 45 °, and spiral can guarantee that this instrument can get into packing smoothly and be 45 ° and the counterclockwise otch that cuts counterclockwise.Under the effect of afterburning assembly, promote afterburning handgrip 5 counterclockwise, in rotating process, the packing on the packing jacking top of bottom, the packing of drawing out is ejected packing box smoothly along the hand of spiral.The effect that increases moment can be played through afterburning assembly, labor strength can be alleviated.And can adjust the installation direction of rotation through afterburning handgrip 5, be convenient to the advance and retreat operation of ripping bar 1.This special tool also is applicable to draws high pressure-conducting disk root, adopts flat mouthful bottle opener to change packing with routine and compares, and this instrument has played convenience, and is not fragile, saves time laborsaving, applied widely effect.
