Abstract
The utility model disclosing a sucker rod wellhead includes a support seat with a stepped through hole arranged at the center, a support pipe arranged at the lower part. An oil scraper is positioned in an oil scraper seat at the upper part. A directing seat with a reversed taper hole at the center is in mesh with a column container arranged at the upper part of the oil scraper. The reversed taper hole matches the diameter of the support pipe. A through hole is arranged at the center of a positioning device, an outlet communicated with the through hole is arranged at the front side of the device. The width of the outlet matches the diameter of the sucker rod. A disc shield matching with the top end surface of the support seat is arranged at the upper part of the direct seat. A reversed 'T' shaped through drove is arranged across through the shield at the upper part of the reversed taper hole. With the 'T' shaped positioning device arranged inside of the through groove and screw threads outside of the support seat, a well cover can be fixed and arranged at the upper part of the support seat.

The wellhead can be covered quickly, thus reducing accidents and facilitating the operators and avoiding contaminating the environment.
Description
Technical field
The utility model is to belong to for conveniently installing or take out the corollary apparatus, particularly sucker rod well-head device that sucker rod is installed in the pumpingh well well head.
Background technology
In the underground work process of petroleum industry, often need to install or take out sucker rod.At present the ancillary facility of producing well well head also exists some problems, as it is rapid inadequately to set well head, when installing or take out sucker rod, makes the fit structure of sucker rod positioning means for positioning unreasonable, and positioner drops easily.These problems all can cause the generation of security incident.In addition, stick crude oil on the sucker rod that is raised up, it is very inconvenient to cause the workman to operate, and causes the pollution to environment.
Summary of the invention
The purpose of this utility model is to provide a kind of sucker rod well-head device, and is easy to operate, safe and reliable when installing or take out sucker rod, can also set well head rapidly, and the minimizing accident takes place, and the workman is easy to operate in addition, avoids the pollution to environment.
The purpose of this utility model is achieved in that a kind of sucker rod well-head device, the center has the bearing body of stairstepping through hole, its underpart is being provided with screwed stay pipe, in the oil wiper seat at an upper portion thereof the oil wiper with vulcanite scraper oil ring is installed, by threaded engagement the guide holder that the center has reverse taper hole is installed in that oil wiper seat top cylindrical cavity is indoor, the small end aperture of reverse taper hole and the aperture of stay pipe adapt, guide holder top is being provided with the disc shoulder block that matches with the bearing body upper surface, the shape opening groove that crosses shoulder block is being set on the top in turbination hole, in shape opening groove, cooperate shape locator is installed, its center of locator has through hole, its front side is being provided with the opening that communicates with through hole, the width of opening and the diameter of sucker rod adapt, the locator rear side is being provided with the inserted link seat with inserted link hole, will shunt in a well by the screw thread on the bearing body outer wall and cover the top that is installed in bearing body.
When using the utility model, shed shut-in well lid and locator on the bearing body earlier, stay pipe of the present utility model is installed on the well head by being threaded, after the sucker rod that will connect by box cupling by Hoisting System proposes, installation positioner, opening by the locator front side makes the through hole at locator center block the bar head of sucker rod, transferring sucker rod cooperates the locator that blocks sucker rod to be fixed in the chamber of the present utility model stably, unload the sucker rod that upgrades, bar head with the sucker rod on Hoisting System and the well head is connected again, mention sucker rod and take out locator, treat with locator sucker rod to be fixed after next box cupling comes out, so circulation can make things convenient for again, safety unload lower sucker rod.If sucker rod is installed in well, its operating process is opposite with the aforesaid operations process.Adopt the utility model when well head is installed or take out sucker rod, easy to operate, the locator positioning security is reliable.Owing in oil wiper seat of the present utility model oil wiper with vulcanite scraper oil ring is installed, when upwards promoting sucker rod, the vulcanite scraper oil ring of oil wiper can will scrape in the well attached to the oil on the sucker rod.Both created good working environment to operating personnel, handled easily alleviates working strength of workers, has saved resource again, has reduced pollution.In operating process, need seal when sitting well head if a variety of causes such as well kick or blowout occur, can unload the handle of installing in the inserted link hole of inserted link seat setting of lower locating device rear side rapidly, will shunt in a well to cover to tighten on bearing body by screw thread gets final product.Can promptly set well head, the generation of minimizing accident.
