Abstract

The invention relates to a continuous oil pipe injection head, in particular to a novel injection head turning device. The device comprises a trailer base, an injection head base, a hydraulic oil cylinder, a rotary bracket and a rotary shaft, and is characterized in that: a cylinder body of the hydraulic oil cylinder is articulated with the trailer base; a hydraulic rod of the hydraulic oil cylinder is articulated with the middle part of the injection head base through an oil cylinder ear plate; and one end of the rotary bracket is fixedly connected with the trailer base, and the other end is connected with the edge part of the injection head base through the rotary shaft. The device can conveniently turn the injection head from an oblique state to a vertical position before the injection head is hoisted, thereby avoiding damage to the oil pipe and injection head caused by a large-angle bending of the continuous oil pipe generated when the injection head in the oblique state is directly hoisted. The novel injection head turning device provided by the invention is simple to operate and is easy to maintain as the hydraulic oil cylinder is convenient to assemble and disassemble; and the device realizes stable turning process and is safe and reliable.

Description

A kind of novel injection head turning device

Technical field

The present invention relates to coiled tubing injection head, relate in particular to a kind of novel injection head turning device.

Background technology

The coiled tubing technology is petroleum machinery field development new technology rapidly, aspect oilfield services, uses more and more widely.During the work of coiled tubing equipment, need injection head be sling from equipment and be installed to well head, owing to height restriction when transporting; Injection head generally is to tilt to be placed on the trailer, operation for ease in addition, and coiled tubing normally is inserted among the injection head; When carrying out lifting operation, if injection head directly lifts by crane when obliquity, can be unstable after injection head is sling; Pipeline damage to being inserted in the injection head is very big, has greatly danger, is to guarantee safety; Best bet is before lifting, to be turned to the upright position to injection head earlier, but does not still control turning device easily at present.

Summary of the invention

The present invention is directed to the deficiency of prior art, provide a kind of simple in structure, easy to operate, can make injection head be turned to the novel injection head turning device of vertical position.

The technical scheme that the present invention solves the problems of the technologies described above is following:

A kind of novel injection head turning device; Comprise trailer bed, injection head base, hydraulic jack, runing rest and axis of rotation; The cylinder body of said hydraulic jack is connected with said trailer bed hinge; The hydraulic stem of said hydraulic jack is connected with the middle part hinge of said injection head base, and an end of said runing rest is fixedly connected with said trailer bed, and the other end is connected through said axis of rotation with said injection head base edge position.

On the basis of technique scheme, the present invention can also do following improvement.

Further, also comprise and be used for the interim support bar that injection head supports in plumbness.

Further, between said trailer bed and runing rest, be provided with bracing piece.

Further, on said trailer bed, be provided with the supporting mechanism that supports when being used for injection head inclination placement.

The invention has the beneficial effects as follows:

1, adopt hydraulic jack to be convenient to installation and removal as Reverse Power, maintenance and operation is simple.

2, switching process is steady, and is safe and reliable.Therefore can not produce the wide-angle bending, can effectively protect oil pipe and injection head injury-free coiled tubing.

Fig. 2 is that injection head of the present invention tilts to place sketch map.

In Fig. 1 and Fig. 2,1, hydraulic jack, 2, runing rest, 3, the injection head base, 4, injection head, 5, axis of rotation, 6, the oil cylinder otic placode, 7, support bar, 8, supporting mechanism, 9, bracing piece, 10, trailer bed.

The specific embodiment

Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.

As depicted in figs. 1 and 2: a kind of novel injection head turning device; Comprisetrailer bed 10,injection head base 3,hydraulic jack 1, runingrest 2 and axis ofrotation 5; The cylinder body ofhydraulic jack 1 is connected withtrailer bed 10 hinges; The hydraulic stem ofhydraulic jack 1 is connected through oil cylinder otic placode 6 hinges with the middle part ofinjection head base 3; One end of runingrest 2 is fixedly connected with saidtrailer bed 10, and the other end is connected through said axis ofrotation 5 withinjection head base 3 edges, is provided withbracing piece 9 betweentrailer bed 10 and theruning rest 2; This novel injection head turning device also comprises and is used for theinterim support bar 7 that injection head supports in plumbness, andtrailer bed 10 is provided with and is used for the supportingmechanism 8 that supports wheninjection head 4 tilts to place.

Coiled tubing equipment is before operation not;Injection head 4 is to tilt to be placed on the supportingmechanism 8 of trailer; When the coiled tubing equipment availability, needinjection head 4 be holded up, lift by crane on the well head, at this time make the hydraulic stem elongation through controlhydraulic jack 1 with crane; Hydraulic stem promotesinjection head base 3 through oil cylinder otic placode 6 and rotates around the axis of rotation on the runing rest 25;, below the injection head base,injection head 4 isfixed injection head 4 when being turned to vertical position, to make things convenient for the operation of next steplifting injection head 4 with 7 of support bars.This device mainly is the upset that realizesinjection head 4 through controlhydraulic jack 1, and whole control process is simple to operate, and is practical and convenient, and after with the injection head lifting, can removehydraulic jack 1 easily.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
