Background technology
In oil, gas drilling, conventionally install and be used for controlling gas, liquid (oil, water etc.) fluid pressure and direction at well head, for suspension sleeve, oil pipe and seal oil pipe and the device of sleeve pipe and each layer of sleeve pipe annular space.And mainly contain the radial load of blank step effect, tensile load and the borehole pressure load of casing wt effect for the suffered load of casing suspension device.Casing suspension device should be able to bear hung casing string weight, is just unlikely to produce necking down distortion and affects passing through of downhole tool.In gas well manufacturing process, gas well is mostly and intermittently produces water, and in part well, foul is more, the large damage wellhead assembly of pressure oscillation before and after easily causing.In addition, present wellhead assembly mostly is integrative-structure, fastening for clamping pipeline, and general wellhead assembly is only set to can pipeline of clamping, and pipeline in use may occur expanding and damages and need to change it, very trouble seems.
Utility model content
The utility model has overcome the deficiencies in the prior art, provide shock-resistant and pick and place pipeline wellhead assembly easily, in the situation that pressure oscillation is larger, also can firmly be fixed on well head, anti-impact force is strong, is also provided with fluting and movable steel plate simultaneously and is convenient to pipeline quick-replaceable and clamping.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: shock-resistant and pick and place pipeline wellhead assembly easily, comprise collar, two fixation steel plates, two movable steel plates, chuck, polylith gusseted part and polylith securing members, two described fixation steel plates be vertically fixed between collar and chuck and with collar and chuck integrative-structure each other, two fixation steel plates are vertically connected between collar and chuck and by bolt and are fixed; Fluting is all set on described collar and chuck, and two flutings are located along the same line; Described chuck is regular polygon structure, be provided with polylith securing member in the side of chuck, enclose around chuck one, securing member and chuck are all undertaken fastening by set bolt, center at chuck arranges retaining ring, retaining ring is clamped in the cavity that fixation steel plate and movable steel plate form, and utilizes polylith gusseted part to support outer the making a circle of retaining ring, and the bottom of every gusseted part is set on surface that sawtooth pattern is vertically fixed on chuck.Gusseted plate bottom is set to zigzag, and support effect is better, is not easy to occur slipping away.
The two ends of slotting on described chuck are provided with square baffle plate, and two direction baffle plates are parallel to each other.
Cross-distribution between fixation steel plate and movable steel plate, and there is gap between 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 are not set between the fluting on fluting and chuck on collar.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model utilization arranges set bolt on chuck, and the rotatable securing member of polylith is set in the side of chuck, and clamp by set bolt, chuck is carried out to multi-faceted multiple-clamping, it is fixing that while retaining ring utilizes gusseted part, movable steel plate and fixation steel plate to support, even if also can not impact this device in the time that well head pressure fluctuation is larger.
The design of 2, slotting on collar and chuck is flowed out an external channel to this device, is convenient to install and change pipeline, also can extract fast in retaining ring even if corrosion is stuck after the long-term use of pipeline.
3, in the slot setting of two end-stopping plates of chuck, prevent from when pipeline from shifting out from fluting chuck fluting two ends to wear and tear, affect its impact resistance.
