Abstract
The invention discloses an impact-resisting well opening device facilitating pipeline taking and placing. The device comprises a top ring, two fixed steel plates, two movable steel plates, a chuck, a plurality of triangle supporting pieces and a plurality of fastening pieces. The two fixed steel plates are vertically fixed between the top ring and the chuck, and the fixed steel plates, the top ring and the chuck form an integrated structure. The two fixed steel plates are vertically connected between the top ring and the chuck and are fixed through bolts. Opening grooves are formed in the top ring and the chuck. The two opening grooves are placed on the same straight line. The chuck is of a regular polygon structure. A plurality of fastening pieces are arranged on the side face of the chuck and surround the chuck by 360 degrees. The fastening pieces and the chuck are fastened through fixing bolts. A locking ring is arranged at the center of the chuck. The locking ring is clamped in a cavity formed by the fixed steel plates and the movable steel plates. The bottom of each triangle supporting piece is arranged to be in a sawtooth shape and is vertically connected to the surface of the chuck in a clamping-fixing mode. According to the impact-resisting well opening device, under the situation that pressure fluctuation is large, the device can be firmly fixed on a well opening, impact resistance is high, meanwhile, the opening grooves and the movable steel plates are arranged, and pipeline quick replacing and clamping are convenient.
Description
Technical field
The present invention relates to wellhead assembly, be specifically related to pick and place pipeline shock-resistant wellhead assembly easily.
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.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provide and pick and place pipeline shock-resistant 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 present invention is by the following technical solutions: pick and place pipeline shock-resistant 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 invention has the beneficial effects as follows:
1, utilization of the present invention 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.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure, Reference numeral 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, set bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited to this.
Embodiment 1:
As shown in Figure 1, the present invention includes collar 1, two fixation steel plates 2, two movable steel plates 3, chuck 4, polylith gusseted part 6 and polylith securing members 7, two described fixation steel plates 2 be vertically fixed between collar 1 and chuck 4 and with collar 1 and chuck 4 integrative-structure each other, two fixation steel plates 2 are vertically connected between collar 1 and chuck 4 and are fixed by bolt.Fluting 9, two flutings are all set on the collar 1 of the present embodiment and chuck 4 and 9 are located along the same line, 9 the two ends of slotting on chuck 4 are provided with square baffle plate 8, two direction baffle plates 8 and are parallel to each other.Between fluting 9 on fluting 9 and chuck 4 on collar 1, fixation steel plate 2 and movable steel plate 3 are not set.
Embodiment 2:
The chuck 4 of the present embodiment is regular polygon structure, be provided with polylith securing member 7 in the side of chuck 4, around chuck 4 one circles, securing member 7 and chuck 4 are all undertaken fastening by set bolt 10, at the center of chuck 4, retaining ring 5 is set, retaining ring 5 is clamped in the cavity that fixation steel plate 2 and movable steel plate 3 form, and utilizes polylith gusseted part 6 to support outer the making a circle of retaining ring 5, and the bottom of every gusseted part 6 is set on surface that sawtooth pattern is vertically fixed on chuck 4.Cross-distribution between the fixation steel plate 2 of the present embodiment and movable steel plate 3, and there is gap between fixation steel plate 2 and movable steel plate 3.Securing member 7 can rotate up and down around the seamed edge of chuck 4.
