Description
Technical field
The utility model relates to instrument, is specifically related to a kind of boll-weevil hanger erecting tools, and promptly boll-weevil hanger is sent into the taking-up instrument.
Background technology
It is to finish by a plurality of jackscrew groups that present known boll-weevil hanger is fixed on the tubing head body, needs a plurality of top wire holes of processing on tubing head, also will design the jackscrew sealing device, complex structure, and complex operation, and also there is the defective of leaking in top wire hole.In order to solve boll-weevil hanger is fixed on deficiency on the tubing head body with a plurality of jackscrews, designed a kind of boll-weevil hanger, processing one cannelure on the cylindrical of boll-weevil hanger, on tubing head body endoporus, also process a cannelure, contact with the cannelure upper surface of tubing head body endoporus with the split ring collar terrace of appearing on the stage, split ring jump ring lower surface contacts with boll-weevil hanger cylindrical cannelure lower surface, so just boll-weevil hanger is fixed on the relevant position of tubing head body endoporus, and the split ring collar under free state cylindrical greater than hole dimension in the tubing head body, in order finishing boll-weevil hanger to be fixed on this purpose on the tubing head body, to need design to send into the taking-up instrument with the split ring collar.
Summary of the invention
The purpose of this utility model is: provide a kind of boll-weevil hanger to send into the taking-up instrument, be used for shrinking the split ring collar on the boll-weevil hanger cylindrical, send into release opening spring collar behind the tubing head body, make in its cannelure that is stuck in tubing head body endoporus, tubing head body and boll-weevil hanger are fixed together closely, retract boll-weevil hanger if desired, then the split ring collar is shunk with this instrument, the split ring collar is deviate from the cannelure of tubing head body endoporus, just desirable flowline hanger.
The technical scheme of the utility model technical solution problem is: this instrument mainly takes out tool body, screw, pressing plate, overcoat and forms by sending into, sending on the taking-up tool body by screw and pressing plate fixed jacket, sending into taking-up tool body upper end bore design has drill rod thread, and sending into the cylindrical design of taking-up tool body lower end has tubing round thread.
The utility model boll-weevil hanger is sent in the taking-up instrument, takes out the tool body axial centre one through hole is arranged sending into, so that drilling fluid passes through; Take out the cylindrical design of tool body lower end sealing ring arranged sending into, with the Seal Oil pipe hanger with send into the radial fit gap of taking out tool body; In the overcoat bore design guiding conical surface is arranged.
Drilling rod is connected with the drill rod thread of sending into taking-up tool body upper end endoporus during work, sending into the tubing round thread that takes out tool body lower end cylindrical is connected with boll-weevil hanger upper end endoporus tubing round thread, the cylindrical guiding conical surface centering of the split ring collar of the endoporus of overcoat and boll-weevil hanger, drilling rod turns clockwise, under the driving of screw thread pair, overcoat moves down along the split ring collar cylindrical guiding conical surface, the split ring collar just slowly shrinks, screw fully up to sending into taking-up tool body and boll-weevil hanger connecting thread, the split ring collar is retracted to minimum dimension, under the self gravitation effect of oil pipe, boll-weevil hanger is located tubing head body relevant position, at this moment counter-clockwise rotary drill rod, overcoat can move up, make the split ring collar state that affranchises, split ring collar respective planes just is stuck in boll-weevil hanger, in the groove of tubing head body, so just with boll-weevil hanger, the tubing head body is fixed together.If maintenance needs to take out boll-weevil hanger, then utilize this instrument that the split ring collar is shunk, the split ring collar is deviate from the cannelure of tubing head body endoporus, just desirable flowline hanger.
The utility model is simple in structure, and is with low cost, and processing ease is easy to use, is boll-weevil hanger is fixed on portable tool on the tubing head body.
