Specific embodiment
Below in conjunction with FIG. 1 to FIG. 3, by preferred embodiment to technology contents of the invention, construction feature, reached purpose And effect is described in detail.
As shown in Figure 1, the external screw thread fetching tool of the eccentric oil pipe extension for locking ring provided by the present invention, includes: First fetching tool ontology 1, section is in T shape, and external screw thread is arranged on the lower half outer wall of the first fetching tool ontology 1, with The internal screw thread being arranged on the through-hole wall of tubing hanger 11 matches；Second fetching tool ontology 2, is fixedly connected with tubing hanger 11, Section is in concave shape, and bottom portion of groove opens up opening, and the lower half of the first fetching tool ontology 1 is protruded into opening setting and taken second The inside of tool body 2 is put, and is connected through a screw thread with the through-hole of tubing hanger 11, the upper half of the first fetching tool ontology 1 is embedding Enter and is arranged in the groove of the second fetching tool ontology 2；It is rotated down the first fetching tool ontology 1 using screw thread, is driven simultaneously 11 vertical downward movement of second fetching tool ontology 2 and tubing hanger, until tubing hanger 11 connect locking with oil pipe four-way 9.
The lower half outer diameter phase of the opening inside diameter of the second fetching tool ontology 2 and the first fetching tool ontology 1 Match.
The upper half side wall of the first fetching tool ontology 1 is provided with convex shape step.
Between 2 groove of the upper half and the second fetching tool ontology of the first fetching tool ontology 1, pressure cap is also set up 4, which is arranged on the step of the first fetching tool ontology 1, and connects by the way that screw 5 and the second fetching tool ontology 2 are fixed It connects, so that realizing connection, i.e. 2 energy of the second fetching tool ontology between the first fetching tool ontology 1 and the second fetching tool ontology 2 It is enough to carry out vertical up-or-down movement with the first fetching tool ontology 1.
O-ring seal 6, realization and tubing hanger are set on the external screw thread of the lower half of the first fetching tool ontology 1 Sealing between 11.
Locating piece 7 is set on the inner wall of the second fetching tool ontology 2, is determined with being arranged on 11 outer wall of tubing hanger Position slot match, the second fetching tool ontology 2 by the way that locating piece 7 is correspondingly arranged in the locating slot of tubing hanger 11 so that It is fixedly connected between tubing hanger 11, and will not rotate with the rotation of the first fetching tool ontology 1.
Further, the locating piece 7 is fixed on the inner wall of the second fetching tool ontology 2 by screw 8.
As shown in Figures 2 and 3, using external screw thread fetching tool of the present invention, it can be achieved that the bias to locking ring The installation of tubing hanger, comprising the following steps:
S1, oil pipe 12 is connected on the first fetching tool ontology 1；Locating piece 7 on second fetching tool ontology 2 is embedding In the locating slot for entering to be arranged in tubing hanger 11；By the external screw thread alignment tubing hanger 11 of the lower half of the first fetching tool ontology 1 Through-hole internal screw thread；
S2, rotation pipeline are screwed in downwards the lower half of the first fetching tool ontology 1 in tubing hanger 11 by screw thread, should The upper half of first fetching tool ontology 1 pushes down the second fetching tool ontology 2 and drives its vertical downward movement, second pick-and-place Tool body 2 drives the also vertical downward movement together of tubing hanger 11 simultaneously；In this process, due to the second fetching tool ontology It is connected and fixed between 2 and tubing hanger 11 by locating piece, therefore the second fetching tool ontology 2 will not be with the first fetching tool The rotation of ontology 1 and small angle rotation occurs；
S3, it is persistently rotated down the first fetching tool ontology 1, until tubing hanger 11 drops to its retaining ring 10 and oil pipe four Logical 9 locking, the first fetching tool ontology 1 can not continue to rotate at this time, and realize its sealing between tubing hanger 11, complete The installation of tubing hanger 11.
By the inverse operation of above-mentioned installation process, the disassembly of tubing hanger 11 can be realized, specifically: first is picked and placed by screw thread The lower half of tool body 1 rotates upwards, so that the retaining ring 10 of tubing hanger 11 pops up；Continue up the first fetching tool of rotation Ontology 1 drives the second fetching tool ontology 2 and 11 upward vertical movement of tubing hanger, until completing the taking-up of tubing hanger 11.
In conclusion the external screw thread fetching tool that the eccentric oil pipe of locking ring of the present invention is hung, structure is simple, if Meter rationally, without occupying larger installation space, by rotation drive tubing hanger vertical up-or-down movement, can quickly and easily install or The eccentric oil pipe of belt removal retaining ring is hung.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
