Description
Technical field
The present invention relates to field of petroleum machinery, particularly, relate to a kind of gripping mechanism of good sealing effect.
Background technique
Oil after exploitation is in transportation process, because the route of transport is long, petroleum pipeline for transporting adopts multi-section type pipeline to transport usually, namely multi-section type pipeline adopts multistage pipeline to be formed by connecting, one end of pipeline is provided with outer pitch thread, the other end is provided with interior pressure screw thread, and adjacent two pipelines realize the connection of pipeline by the cooperation of interior pitch thread and outer pitch thread.Owing to there is larger pressure in oil transportation process, in order to improve the structure stability of pipeline junction, usually needing pipeline junction is provided with gripping mechanism, for the place that reinforces the connection, avoiding pipeline junction to come off in petroleum transportation process.
Existing gripping mechanism adopts bolt to fix usually, troublesome poeration, and sealing is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of gripping mechanism of good sealing effect, to overcome the problem that the operation of existing gripping mechanism is inconvenient, sealing is poor.
The present invention's adopted technological scheme that solves the problem is: the gripping mechanism of good sealing effect, comprise 2 arcuate structures cooperatively interacted, 2 arcuate structure one end are hinged, the other end is provided with lug, one of them lug is hinged with fixing rod, fixing rod is provided with tapped through hole I, another lug offers the U-groove bevel coordinated with fixing rod, the sidewall of U-groove bevel is provided with the tapped through hole II coordinated with tapped through hole I, fixing rod is bolted in U-groove bevel, the inwall of described arcuate structure is provided with rubber pad, described rubber pad is set to ledge structure, the sidewall of ledge structure is provided with arc convex.
The existing gripping mechanism for petroleum transportation pipeline joint normally adopts 2 semi-circular structure of separating, the two ends of 2 semi-circular structure are fixed by multiple bolt, need tighting a bolt one by one, troublesome poeration when adopting said structure to be fixed pipeline junction, sealing is also poor, 2 arcuate structures cooperatively interacted of the present invention specifically refer to that 2 arcuate structures just surround a round structure and coordinate with pipeline outer wall, described ledge structure specifically refers to that rubber pad just coordinates with the outer wall of pipeline junction, pipeline junction is owing to being the pipeline outer wall by being set in compared with the pipeline of Large Diameter Pipeline compared with pipe with small pipe diameter, and then form ring-shaped step at pipeline junction, ledge structure of the present invention is just fitted with ring-shaped step, the sidewall of described ledge structure specifically refers to the face that ledge structure and pipeline sagittal plane are fitted, the sealing of pipeline junction is conducive to improving by being provided with arc convex at the sidewall of ledge structure, working procedure of the present invention: the joint 2 arcuate structures being placed on pipeline, the ledge structure of rubber pad is arranged on the ring-shaped step place of pipeline junction, arc convex is made to be fitted on the annular radial face of large-size pipeline, rotating arcuate structure makes 2 lugs cooperatively interact, then fixing rod is fixed in U-groove bevel by bolt and then realizes gripping mechanism and pipeline junction is fixed, owing to being provided with rubber pad, rubber pad is set to ledge structure, the sidewall of ledge structure is provided with arc convex, can not only avoid arcuate structure directly and the frictionally damage that causes of tube contacts, and under the effect of extruding rubber pad, improve the sealing of gripping mechanism, liquid is avoided to flow out from the gap of pipeline junction, the present invention is by arranging 2 arcuate structures be hinged, the movable end of arcuate structure arranges the fixing rod and U-groove bevel that cooperatively interact, fixing rod is fixed in U-groove bevel by bolt and then realizes gripping mechanism and pipeline junction is fixed, structure is simple, easy to operate, so, the present invention overcomes existing gripping mechanism operation inconvenience, the problem of sealing difference.
Further, arcuate structure inwall is provided with groove, and rubber pad stupefiedly coordinates the inwall being fixed on arcuate structure with groove by convex.
Guarantee the soundness that rubber pad is fixing.
Further, the surface of rubber pad is set to flank of thread.
Flank of thread effectively can increase the frictional force of contactant, avoids the problem occurring skidding.
Further, be provided with inner sleeve in arcuate structure, the width of inner sleeve is greater than the width of arcuate structure, and described rubber pad is arranged in inner sleeve.
The setting of inner sleeve can increase the area of contact of gripping mechanism and pipeline, improves the structure stability of gripping mechanism and fixing soundness.
Further, inner sleeve adopts teflon to make.
Teflon is prior art material, has corrosion resistant advantage, can improve the working life of poly-inner sleeve.
Further, arcuate structure adopts hard aluminium alloy to make.
Hard aluminium alloy is prior art material, has the advantage that the large quality of hardness is light, under the prerequisite of intensity meeting arcuate structure, reduce its weight, easy to use.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by arranging 2 arcuate structures be hinged, the movable end of arcuate structure arranges the fixing rod and U-groove bevel that cooperatively interact, be fixed in U-groove bevel by fixing rod by bolt and then realized gripping mechanism and fixed by pipeline junction, structure is simple, easy to operate.
2, the present invention is by being provided with rubber pad, rubber pad is set to ledge structure, the sidewall of ledge structure is provided with arc convex, can not only avoid arcuate structure directly and the frictionally damage that causes of tube contacts, and under the effect of extruding rubber pad, improve the sealing of gripping mechanism, avoid liquid to flow out from the gap of pipeline junction.
