Description
Technical field
The present invention relates to coiled tubing construction equipment, specifically coiled tubing injection head quick insertion drag chain.
Background technology
With the development of oil field construction technology, coiled tubing construction is needed increasingly to increase, different construction types need
Coiled tubing size also tend to variation.Because the diameter of coiled tubing is bigger, it is flexible poorer, will be continuous in site operation
The process difficulty that oil pipe imports injection head is also higher, it is necessary to which crane expends the time, wasted with merging using larger operating space
Manpower and materials, reduce the efficiency of construction.
The content of the invention
It is an object of the invention to provide coiled tubing injection head quick insertion drag chain, crane can not needed to coordinate
In the case of coiled tubing is quickly imported into injection head.The labor intensity that coiled tubing is imported during injection head is alleviated, is subtracted
Labour's needs are lacked, have been also convenient for being assembled in the environment of limited space, especially suitable major diameter coiled tubing.
In order to reach above-mentioned purpose, present invention employs following technical scheme, coiled tubing injection head quick insertion is oriented to
Chain, including locking mandrel, adapter sleeve, plug, the locking mandrel lower end are connected by screw thread with being connected set upper side, the plug
Upper end is hinged on adapter sleeve lower end, and the locking mandrel outer cover is equipped with to be mounted for blocking the card hung on coiled tubing inwall
Put.
The card hang device includes coiled tubing slips, coiled tubing slips lock sleeve, and the coiled tubing slip sleeve exists
Locking mandrel outer wall, the locking mandrel upper end outer wall are in inverted cone structure, and the coiled tubing slips upper end is provided with card
Tooth, latch are enclosed on the outer wall of locking mandrel upper end outer wall inverted cone structure, outer dome are set in the middle part of the coiled tubing slips
Land, the coiled tubing slips outer wall below annulus platform are equipped with coiled tubing slips lock sleeve, coiled tubing card by thread bush
Watt lock sleeve lower end withstands on adapter sleeve upper surface, and coiled tubing slips lock sleeve and coiled tubing slips are rotated against, even
Continuous tubing slip drives the latch of upper end to rise, and hangs over coiled tubing inwall as inverted cone structure is flared out card.
The screw for loading screw is opened up on the coiled tubing slips lock sleeve, after completing to block extension process, uses spiral shell
Screw top lives coiled tubing slips outer wall and carries out locking coiled tubing slips and coiled tubing slips lock sleeve.
Also the screw for loading screw is offered on the adapter sleeve, locking mandrel outer wall is withstood by the screw penetrated
Carry out locking adapter sleeve and locking mandrel.
The adapter sleeve lower end connects plug by least one universal joint, and the universal joint upper and lower side is hingedly connected
Set and plug.
Compared to prior art, the invention has the advantages that：
（1）Simple in construction, installation operation is easy, laborsaving；
（2）Without crane and the troublesome operation of personnel, you can complete the process that coiled tubing imports injection head；
（3）It is remarkably improved the major diameter coiled tubing in-site installation efficiency of flexible difference.
Brief description of the drawings
Fig. 1 is the structural representation of the coiled tubing injection head quick insertion drag chain of the present invention.
In figure：Locking mandrel 1, coiled tubing slips 2, coiled tubing slips lock sleeve 3, adapter sleeve 4, universal joint 5, plug
6, screw 7,8, latch 21.
Embodiment
Detailed description for the present invention and technology contents, coordinate brief description of the drawings it is as follows, but accompanying drawing only provide reference with
Purposes of discussion, not it is used for being any limitation as the present invention.
Coiled tubing injection head quick insertion drag chain, including locking mandrel 1, adapter sleeve 4, plug 6, the locking mandrel
Lower end is connected by screw thread with being connected set upper side, and the plug upper end is hinged on adapter sleeve lower end, the locking mandrel outer cover
Equipped with the card hang device hung over for card on coiled tubing inwall.The card hang device includes coiled tubing slips 2, coiled tubing
Slips lock sleeve 3, for the coiled tubing slip sleeve in locking mandrel outer wall, the locking mandrel upper end outer wall is in inverted cone knot
Structure, the coiled tubing slips upper end are provided with latch 21, and latch is enclosed on the outer of locking mandrel upper end outer wall inverted cone structure
Wall, sets evagination annulus platform in the middle part of the coiled tubing slips, and the coiled tubing slips outer wall below annulus platform passes through thread bush
Equipped with coiled tubing slips lock sleeve, coiled tubing slips lock sleeve lower end withstands on adapter sleeve upper surface, coiled tubing slips lock
Only set and coiled tubing slips are rotated against, and coiled tubing slips drives the latch of upper end to rise, and with inverted cone
Structure is flared out card and hangs over coiled tubing inwall.
The screw for loading screw 8 is opened up on the coiled tubing slips lock sleeve, after completing to block extension process, uses spiral shell
Screw top lives coiled tubing slips outer wall and carries out locking coiled tubing slips and coiled tubing slips lock sleeve.On the adapter sleeve
The screw for loading screw 7 is offered, withstanding locking mandrel outer wall by the screw penetrated carries out locking adapter sleeve and locking
Mandrel.The adapter sleeve lower end connects plug by least one universal joint 5, and the universal joint upper and lower side is hingedly connected set
And plug.
As shown in figure 1, the locking mandrel 1 is arranged in coiled tubing slips 2, its exterior is locked equipped with coiled tubing slips
Only cover 3, between coiled tubing slips lock sleeve 3 and coiled tubing slips 2 use be threadedly coupled, locking mandrel 1 makes with adapter sleeve 4
After threaded connection, fastened with screw 7.It is connected with universal pitch chain 5 and plug 6 under it in turn, screw 8 is loaded on coiled tubing slips
In screw on lock sleeve 3.
In use, latch 21 is stretched into continuous pipe, rotation coiled tubing lock sleeve 3, coiled tubing slips 2 opens, card
