Description
Technical field
The present invention relates to wellhead assembly, be specifically related to pick and place pipeline convenient impact resistance wellhead assembly.
Background technology
In oil, gas drilling, generally install at well head and be used for controlling air-liquid (oil, water etc.) fluid pressure and side
To, for suspension sleeve, oil pipe and seal oil pipe and sleeve pipe and the device of each layer casing annulus.And hang for sleeve pipe
Load suffered by device mainly has the radial load of blank step effect, the tensile load of casing wt effect and borehole pressure
Load.Casing suspension device should be able to bear hung casing string weight, is just unlikely to produce necking down deformation and affect down-hole work
Passing through of tool.During gas well liquid loading, gas well is mostly interval and produces water, and in part well, foul is more, easily causes and front and back presses
Fluctuation big damage wellhead assembly.It addition, present wellhead assembly is structure as a whole more, for the fastening of clamping pipeline, typically
Wellhead assembly is set to be only capable of piece pipeline of clamping, and pipeline is in use likely to occur expansion and damages and need to enter it
Row is changed, it appears bother very much.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that pick and place pipeline convenient impact resistance wellhead assembly, at pressure wave
Also can be firmly fixed on well head in the case of moving relatively greatly, anti-impact force is strong, is additionally provided with fluting with activity steel plate just simultaneously
In pipeline quick-replaceable and clamping.
For solving above-mentioned technical problem, the present invention by the following technical solutions: pick and place pipeline convenient impact resistance well head
Device, including collar, two pieces of fixation steel plates, two blocks of movable steel plates, chuck, polylith gusseted part and polylith securing member, described
Two pieces of fixation steel plates be vertically fixed between collar and chuck and be structure as a whole mutually with collar and chuck, two pieces of fixation steel plates
It is vertically connected between collar and chuck and is fixed by bolt；Being respectively provided with fluting on described collar and chuck, two open
Groove is located along the same line；Described chuck is regular polygon structure, the side of chuck is provided with polylith securing member, around chuck
One circle, securing member and chuck are all fastened by fixing bolt, and in the centrally disposed retaining ring of chuck, retaining ring is clamped on solid
Determine steel plate and in cavity that movable steel plate is formed, outer the making a circle in retaining ring utilize polylith gusseted part to be supported,
The bottom of every piece of gusseted part is set to sawtooth pattern and is vertically fixed on the surface of chuck.Arrange bottom gusseted plate
For zigzag, support effect is more preferable, it is not easy to occur slipping away.
On described chuck, the two ends of fluting are provided with square baffle plate, and two square baffle plates are parallel to each other.
Gap is there is between cross-distribution between fixation steel plate and movable steel plate, and fixation steel plate and movable steel plate.
Securing member can rotate up and down around the seamed edge of chuck.
Fixation steel plate and movable steel plate it is not provided with between fluting on collar and the fluting on chuck.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention utilizes and arranges fixing bolt on chuck, and arranges the rotatable securing member of polylith in the side of chuck,
And carry out clamping by fixing bolt, and chuck is carried out multi-faceted multiple-clamping, retaining ring utilizes gusseted part, activity simultaneously
Steel plate and fixation steel plate are supported fixing, even if also will not impact this device when well head pressure fluctuation is bigger.
2, on collar and chuck, the design of fluting flows out an external channel to this device, it is simple to installs and changes pipeline,
Also can quickly extract in retaining ring even if corrosion is stuck after pipeline life-time service.
3, slot at chuck the setting of two end-stopping plates, prevent pipeline from when fluting removal, chuck fluting two ends being ground
Damage, affect its impact resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, reference is expressed as: 1, collar；2, fixation steel plate；3, movable steel plate；4, chuck；5, retaining ring；
6, gusseted part；7, securing member；8, baffle plate；9, fluting；10, fixing bolt.
Detailed description of the invention
The present invention is further elaborated below in conjunction with the accompanying drawings, and embodiments of the invention are not limited to this.
Embodiment 1:
As it is shown in figure 1, the present invention includes collar 1, two pieces of fixation steel plates 2, two pieces of movable steel plates 3, chuck 4, polylith triangles
Support member 6 and polylith securing member 7, two pieces of described fixation steel plates 2 be vertically fixed between collar 1 and chuck 4 and with collar 1 and
Chuck 4 is structure as a whole mutually, and two pieces of fixation steel plates 2 are vertically connected between collar 1 and chuck 4 and are fixed by bolt.
Being respectively provided with fluting 9 on the collar 1 of the present embodiment and chuck 4, two flutings 9 are located along the same line, the two ends of fluting 9 on chuck 4
Being provided with square baffle plate 8, two square baffle plates 8 are parallel to each other.Do not have between fluting 9 on collar 1 and the fluting 9 on chuck 4
Fixation steel plate 2 and movable steel plate 3 are set.
Embodiment 2:
The chuck 4 of the present embodiment is regular polygon structure, the side of chuck 4 is provided with polylith securing member 7, around chuck 4
One circle, securing member 7 and chuck 4 are all fastened by fixing bolt 10, in the centrally disposed retaining ring 5 of chuck 4, retaining ring 5
It is clamped on fixation steel plate 2 and in cavity that movable steel plate 3 is formed, outer the making a circle in retaining ring 5 utilizes polylith gusseted
Part 6 is supported, and the bottom of every piece of gusseted part 6 is set to sawtooth pattern and is vertically fixed on the surface of chuck 4.This reality
