Abstract
The utility model provides a pumping unit polish rod reinforced anti-falling cap. The pumping unit polish rod reinforced anti-falling cap comprises a polish rod and an anti-falling cap body. The top end of the polish rod is connected with the anti-falling cap body in a threaded mode. The pumping unit polish rod reinforced anti-falling cap is characterized in that an embedded part is arranged, a horizontal hole is formed in the anti-falling cap body, the polish rod is provided with a horizontal hole correspondingly, and the embedded part is inserted into the horizontal hole of the anti-falling cap body and the horizontal hole of the polish rod. According to the pumping unit polish rod reinforced anti-falling cap, the pumping unit polish rod can be preventing from falling off, well patrol staff can be prevented from being injured personally, safety production of a rod pumped well can be guaranteed, and oil extraction efficiency is improved.
Description
Technical field
The utility model relates to a kind of oil-extractor polish-rod and reinforces anti-raising one's hat.
Background technology
Anti-raising one's hat is mounted in the safety component at beam pumping unit wellhead polish rod top, when the oil pumper equipment faults such as square clamp pine, polished rod break or hair plait on the polished rod break occur, can cause polished rod to fall in the oil pipe, the downhole tools such as sucker rod, oil well pump are damaged.Because the long upper and lower operation of pumping unit horsehead, the contacting surface of polished rod top and horse head rubs repeatedly, bears the fluctuating load of oil pumper and the vibrations of oil pumper, causes easily the anti-inefficacy of threading off of raising one's hat, and prevents raising one's hat just not have like this answering role.When the anti-dropout of raising one's hat was lost efficacy, the post workman need to reinstall operation, and this belongs to work high above the ground (beam hanger for pumping machine adds the remaining height of light to be had about 4 meters), the operator stands on the well head polished rod eye, and ball woll plait on the other hand is on the other hand with 24, and " pipe wrench is fastening; operate very difficultly, wastes time and energy.If can not in time find to process, cause anti-raising one's hat to fall the personnel of patrolling and examining of pounding, easily cause personal injury, form potential safety hazard.If light rod-broken can cause that crude oil causes environment pollution from the well head ejection, serious meeting is broken the oil pipe big and heavy stone and is easily caused deep well pump to break, and causes the operation that stops production, thereby affects the normal production of oil well, causes the crude output loss.
Summary of the invention
The utility model provides a kind of oil-extractor polish-rod that prevents that oil-extractor polish-rod from coming off to reinforce anti-raising one's hat for solving above-mentioned problems of the prior art.
The utility model is to address the above problem the technical scheme that adopts to be: a kind of oil-extractor polish-rod is reinforced anti-raising one's hat, comprise polished rod and anti-raising one's hat, the top of described polished rod is connected with the anticreep cap thread, it is characterized in that also being provided with insert, be provided with transverse holes anti-raising one's hat, correspondence is provided with transverse holes on polished rod, and insert inserts in the transverse holes of anti-transverse holes of raising one's hat and polished rod.
By technique scheme, described insert is bolt, and the transverse holes on anti-the raising one's hat is screwed hole, and transverse holes corresponding on the polished rod is screwed hole, and bolt screws in anticreep cap thread hole and the polished rod screwed hole.
The utility model technique effect relative and that prior art is obtained is: the utility model can prevent that oil-extractor polish-rod from coming off, and avoids patrolling the well employee and is subject to personal injury at well head, guarantees the safety in production of rod-pumped well, improves oil recovery efficiency.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Among the figure: 1, anti-raising one's hat, 2, polished rod, 3, bolt.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, it comprises polished rod 2 and prevents raising one's hat 1 that an end of polished rod 2 is connected with the anticreep cap thread, is provided with transverse holes anti-raising one's hat, and correspondence is provided with transverse holes on polished rod, and insert inserts in the transverse holes of anti-transverse holes of raising one's hat and polished rod.
Described insert is bolt 3, is screwed hole in anti-transverse holes of raising one's hat, and the transverse holes on the polished rod corresponds to screwed hole, and bolt 3 screws in anticreep cap thread hole and the polished rod screwed hole.
Anti-raising one's hat 1 do not change place where troops were originally stationed raise one's hat 1 structure, profile, size after improving, and uses reliable.The utility model can effectively prevent from raising one's hat dropout, polished rod comes off, and guarantees the safety in production of rod-pumped well, improves oil recovery efficiency.
