Abstract
The utility model provides a chain for guiding a continuous oil pipe to be rapidly inserted into an injection head. The chain comprises a locking mandrel, a connecting sleeve and a plug. The lower end of the locking mandrel is connected with the upper end of the connecting sleeve through threads. The upper end of the plug is hinged to the lower end of the connecting sleeve. The locking mandrel is sleeved with a clamping and hanging device for being clamped and hung on the inner wall of the continuous oil pipe. The lower end of the connecting sleeve is connected with the plug through at least one universal joint. The upper end of the universal joint and the lower end of the universal joint are hinged to the connecting sleeve and the plug respectively. By means of the chain, the continuous oil pipe can be rapidly guided into the injection head under the condition that no crane needs to be used in cooperation with the chain. Labor intensity in the process that the continuous oil pipe is guided into the injection head is lowered, labor requirements are reduced, assembly is facilitated in the space-limited environment, and the chain is particularly suitable for large-diameter continuous oil pipes.

The purpose of this utility model also can be achieved by the following technical measures:
Described card hang device comprises coiled tubing slips, coiled tubing slips lock sleeve, described coiled tubing slip sleeve is at locking axle outer wall, described locking axle upper end outer wall is inverted cone structure, described coiled tubing slips upper end is provided with latch, latch is enclosed within the outer wall of locking axle upper end outer wall inverted cone structure, described coiled tubing slips middle part arranges evagination annulus platform, the coiled tubing slips outer wall of annulus platform below is equipped with coiled tubing slips lock sleeve by thread bush, coiled tubing slips lock sleeve lower end withstands on adapter sleeve upper surface, coiled tubing slips lock sleeve carries out relative rotation with coiled tubing slips, coiled tubing slips drives the latch of upper end to rise, and along with inverted cone structure is outwards opened card and hung over coiled tubing inwall.
On described coiled tubing slips lock sleeve, offer the screw for packing screw into, hang after operation when completing card, withstand coiled tubing slips outer wall with screw and carry out locking coiled tubing slips and coiled tubing slips lock sleeve.
On described adapter sleeve, also offer the screw for packing screw into, withstand locking axle outer wall by the screw penetrating and carry out locking adapter sleeve and locking axle.
Described adapter sleeve lower end connects plug by least one universal joint, and described universal joint upper and lower side is articulated and connected respectively and overlaps and plug.
The utlity model has following beneficial effect:
(1) simple in structure, fitting operation is easy, laborsaving;
(2), without crane and personnel's troublesome operation, can complete the process of coiled tubing importing injection head;
(3) can significantly improve the on-the-spot installation effectiveness of major diameter coiled tubing of flexible difference.
accompanying drawing explanation:
Fig. 1 is the structural representation of coiled tubing injection head quick insertion drag chain of the present utility model.
In figure: locking axle 1, coiled tubing slips 2, coiled tubing slips lock sleeve 3, adapter sleeve 4, universal joint 5, plug 6, screw 7,8, latch 21.
the specific embodiment:
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the utility model to be limited.
Coiled tubing injection head quick insertion drag chain, comprise locking axle 1, adapter sleeve 4, plug 6, described locking axle lower end is connected with adapter sleeve upper end by screw thread, described plug upper end is hinged on adapter sleeve lower end, and described locking axle outer cover is equipped with for card and hangs over the card hang device on coiled tubing inwall.Described card hang device comprises coiled tubing slips 2, coiled tubing slips lock sleeve 3, described coiled tubing slip sleeve is at locking axle outer wall, described locking axle upper end outer wall is inverted cone structure, described coiled tubing slips upper end is provided with latch 21, latch is enclosed within the outer wall of locking axle upper end outer wall inverted cone structure, described coiled tubing slips middle part arranges evagination annulus platform, the coiled tubing slips outer wall of annulus platform below is equipped with coiled tubing slips lock sleeve by thread bush, coiled tubing slips lock sleeve lower end withstands on adapter sleeve upper surface, coiled tubing slips lock sleeve carries out relative rotation with coiled tubing slips, coiled tubing slips drives the latch of upper end to rise, and along with inverted cone structure is outwards opened card and hung over coiled tubing inwall.
