Abstract
The utility model provides floating clamping device for continuous tube transfusion head, being composed of multi-stage hinge connecting thrust block, clamping block, chain, continuous tube and hydraulic oil cylinder. The hydraulic oil cylinder is fixed on the multi-stage hinge connecting thrust block, which being attached to the chain, the clamping block is mounted to the continuous tube and together with the chain as a whole. The multi-stage hinge connecting thrust block is composed of multi-stage thrust blocks in different sizes. The lower thrust block can rotates a certain angle around pin roll according to receiving force to change the force applied to clamping block by thrust block, so that the clamping force applied to continuous tube by the clamping block is equal. The advantage is simple operation, time-saving and labor-saving, low cost, self-regulating, equal receiving force, easy to operate and maintain; being applied in continuous tube operation apparatus, avoiding deformation or speedup abrasion of the continuous tube caused by heterogeneous clamping force, so as to service life in continuous tube operation.
Description
Technical field:
The utility model relates to a kind of continuous tube injection head clamping device.
Background technology:
Pipe (claiming coiled tubing again) technology has now become a focus in world's oil and gas industry technical research and application continuously, is widely used in the various operations of oilfield prospecting developing, plays an increasingly important role in exploration of oil and gas field and exploitation.
Continuously pipe is at operation process: pipe launches from cylinder continuously, is lowered to oil well through leading truck, injection head, is wound on the cylinder through injection head, leading truck from oil well again.Pipe is gone into the well and is promoted all and by control injection head grip block continuous tube grip power finished continuously, difference along with well depth, the size of chucking power is also different, and pipe is out of shape or accelerated wear test by folder owing to the grip block discontinuity causes continuously easily in the clamping process.
In recent years, along with the continuous expansion of connecting pipes way and range of application, caliber constantly increases, and depth of implements constantly extends, and the raising of suffered load, and continuous tube injection head clamping problem more seems most important.Be the key in application factor of managing continuously the application life of pipe continuously, and it is the principal element of the continuous tube lifetime of influence that injection head clamping inequality causes pipe distortion continuously or accelerated wear test, so the improvement of injection head clamping device plays an important role to continuous pipe development.
Present existing continuous tube injection head clamping device is that grip block is contained on the big pushing block, fix, this big pushing block is by the parallel together promotion of a plurality of hydraulic jacks, pushing block and grip block are not all regulated surplus, so grip block can be because oil cylinder be asynchronous, the power difference that produces, chucking power are also different, cause continuous pipe local distortion easily.
Summary of the invention:
The purpose of this utility model is to provide for fear of above deficiency a kind of continuous tube injection head clamping device that floats.
The purpose of this utility model is achieved in that a kind of continuous tube injection head clamping device that floats, by multistagely be hinged pushing block, add hold piece, chain, pipe, hydraulic jack etc. are formed continuously, it is characterized in that hydraulic jack is fixed on multistage being hinged on the pushing block, and the multistage pushing block that is hinged is attached on the chain, add and hold piece and be installed on the continuous pipe, and with chain be one.Being hinged multistage pushing block is made up of the multistage pushing block that varies in size.Subordinate's pushing block can rotate to an angle around bearing pin according to stressing conditions, thereby changes the power that pushing block imposes on grip block, make grip block to continuous pipe to add the power of holding even.
Compared with prior art, the utility model has the advantages that simple to operately, time saving and energy saving, cost is low, regulates automatically, stressed evenly, easy operating and maintenance; Be applied to manage continuously in the implement, the continuous pipe that can avoid causing because of chucking power is inhomogeneous is out of shape or accelerated wear test, thereby improves the application life of pipe operation process continuously.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Among the figure: 1, the multistage pushing block that is hinged; 2, grip block; 3, chain; 4, manage continuously; 5, hydraulic jack.
The specific embodiment:
A kind of continuous tube injection head clamping device that floats, be by the multistage pushing block 1 that is hinged, add and hold piece 2, chain 3, manage 4 continuously, hydraulic jack 5 compositions such as grade, it is characterized in that hydraulic jack 5 is fixed on multistage being hinged on the pushing block 1, and the multistage pushing block 1 that is hinged is attached on the chain 3, add and hold piece 2 and be installed on the continuous pipe 4, and with chain 3 are one, being hinged multistage pushing block 1 is made up of the multistage pushing block that varies in size, subordinate's pushing block can rotate to an angle around bearing pin according to stressing conditions, thereby change the power that pushing block imposes on grip block, make grip block to continuous pipe to add the power of holding even.
When 5 hydraulic jacks promote 1 multistage when being hinged pushing block, pushing block is delivered to power on 3 chains, drive 2 grip blocks step up 4 continuously the pipe, because the implantation site is different with angle down for pipe continuously, pipe is given the reaction force difference of each grip block continuously, reaction force acts is to the multistage pushing block that is hinged that connects chain, pushing block near the chain one-level can rotate to an angle around the bearing pin that links to each other with the upper level pushing block according to stressed difference, thereby adjust active force to continuous pipe, if changing greatly, angle affacts again in the pushing block of back one-level, and the like, can design multistage pushing block.
Claims (3)
1, the unsteady clamping device of a kind of continuous tube injection head, by multistagely be hinged pushing block, add hold piece, chain, pipe, hydraulic jack etc. are formed continuously, it is characterized in that hydraulic jack is fixed on multistage being hinged on the pushing block, and the multistage pushing block that is hinged is attached on the chain, add and hold piece and be installed on the continuous pipe, and with chain be one.
2, the unsteady clamping device of a kind of continuous tube injection head according to claim 1 is characterized in that being hinged multistage pushing block and is made up of the multistage pushing block that varies in size.
3, the unsteady clamping device of a kind of continuous tube injection head according to claim 1 and 2 is characterized in that subordinate's pushing block can rotate to an angle around bearing pin according to stressing conditions.
