Abstract
The utility model relates to a take many frameworks spherical pig of damping function, the spherical pig includes: a rigid framework, a compression spring and a rubber cup; the method is characterized in that: the three rigid frameworks are connected through two compression springs, and a rubber cup is arranged on each rigid framework; the rubber cup is composed of a straight surface and an inclined surface, and the edge of the rubber cup is in a sawtooth shape. When the spherical pig is used in the pipeline, the sawtooth-shaped edge of the rubber cup is attached to the wall of the pipeline, when the spherical pig passes through a bend, the spherical pig passes through the bend pipeline due to the deformation of the compression spring, and the spherical pig is restored to the original state after passing through the bend pipeline and continues to run in the pipeline. The utility model discloses following beneficial effect has: the spherical pig is flexible, avoids the card ball trouble, and spring coupling has certain damping effect, has reduced the damage to spherical pig and pipeline, and the sawtooth edge leather cup has better spherical pig effect, low cost, facilitate promotion.
Description
Technical Field
The utility model relates to a take many frameworks spherical pig of damping function for among natural gas line pigging technology belongs to the defeated field of gas reservoir collection.
Background
In the construction and operation of long-distance pipelines for natural gas, pigging is a very important and risky operation. For newly-built pipelines, more construction operation residues are left, more water is left during pipeline pressure tests, the main purpose of pipe cleaning is to remove water and construction residues in the pipelines, including welding rods, welding slag, wood sticks, stones, soil, sand, lunch boxes, plastics and burrs, if the residues are not removed, a downstream filter and a downstream valve can be blocked, a compressor is damaged, for pipelines which are put into production and run, the main purpose of pipe cleaning is to remove FeS iron powder, and the smoothness of pipe walls and the pipe conveying efficiency are improved; for the pipeline carrying the moisture, the water in the pipeline can be cleaned out through the cleaning pipe; for pipelines coming out of a gas field or a ground reservoir, condensate liquid such as light hydrocarbon and the like can be discharged through a pipeline cleaning, so that the pipe wall smoothness and the pipe conveying efficiency are improved.
However, in the actual pipe cleaning process, the pipe condition is complex, the pipeline is tortuous, and the ball clamping fault caused by a large amount of impurities in the pipeline can cause larger loss; meanwhile, the current pipe cleaner vibrates greatly when running in a pipeline, so that not only is the skeleton of the pipe cleaner broken, but also the following threats are caused to the pipeline: the crack of the pipeline is rapidly expanded and even the pipeline is broken; equipment damage; pipeline connection department leaks, reduces pipeline life, and this patent is exactly in order to solve the easy card ball of spherical pig now, and the big problem of vibration during the dredging pipe to be suitable for the dredging pipe operation under the multiple operating mode, improve the dredging pipe benefit.
Disclosure of Invention
The utility model aims at: provides a multi-skeleton spherical pig with a vibration reduction function.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a multi-skeleton spherical pig with a vibration damping function comprises three rigid skeletons, two compression springs and three rubber cups; the three rigid frameworks are connected through two compression springs, and a rubber cup is arranged on each rigid framework; the rubber cup is composed of a straight surface and an inclined surface, and the edge of the rubber cup is in a sawtooth shape.
When the spherical pig is used in a pipeline, the sawtooth-shaped edge of the rubber cup is attached to the pipe wall, the spherical pig moves along with the pipeline, when the spherical pig passes through a bend of the pipeline, the compression spring deforms due to the fact that the pipe wall applies force to the rubber cup, the spherical pig is bent according to the shape of the pipeline, the purpose of preventing the spherical pig from being blocked is achieved by bending the pipeline, after the spherical pig passes through the bend, the spring returns to the original shape, and the spherical pig continues to move in the residual pipeline until the operation of the spherical pig is finished.
The utility model discloses following beneficial effect has: (1) the spherical pig can be bent, so that the spherical pig can conveniently pass through a bent part of a pipeline, and the spherical pig is prevented from being blocked; (2) the spring connection has a certain vibration damping effect, so that the damage to the spherical pig and the pipeline is reduced; (3) the leather cup with the sawtooth-shaped edge has better pipe cleaning effect; (4) low cost and convenient popularization.

In the figure: 1. rigid frame, 2 compression spring, 3 rubber cup.
Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 1, a multi-skeleton spherical pig with vibration reduction function comprises: three rigid frameworks 1, two compression springs 2 and three rubber cups 3; the method is characterized in that: the three rigid frameworks 1 are connected through two compression springs 2, and a rubber cup 3 is arranged on each rigid framework; the rubber cup 3 is composed of a straight surface and an inclined surface, and the edge of the rubber cup is in a sawtooth shape.
When this spherical pig is used in the pipeline, the zigzag edge of its rubber leather cup 3 is laminated with the pipe wall, and the spherical pig is along with the pipeline operation, when the pipeline bend, because the pipe wall gives the power of applying for rubber leather cup 3, compression spring 2 takes place deformation for the spherical pig is crooked according to the pipeline shape, in order to reach through crooked pipeline, prevent the purpose of card ball trouble, treat after the bend, the spring reconversion, the spherical pig continues the operation in the remaining pipeline, until accomplishing the cleaning operation.
The utility model discloses following beneficial effect has: (1) the spherical pig can be bent, so that the spherical pig can conveniently pass through a bent part of a pipeline, and the spherical pig is prevented from being blocked; (2) the spring connection has a certain vibration damping effect, so that the damage to the spherical pig and the pipeline is reduced; (3) the leather cup with the sawtooth-shaped edge has better pipe cleaning effect; (4) low cost and convenient popularization.
