Description
Technical field
This utility model relates to a kind of pipeline shock-damping structure, particularly relates to the damping of a kind of convenient diameter-variable pipe tuning quality
Device structure.
Background technology
Known, pipeline plays very important effect in oil gas field, and pipeline can bear a series of under normal circumstances
External force, such as the deadweight of pipeline itself, fluid matasomatism thrust in pipeline, expand with heat and contract with cold cause thermal stress, oscillating load etc..
Under the effect of these external force, pipeline can deform upon, and especially at pipe joint, friction is serious, in the course of time, then there will be fatigue
Damage, cause it to leak, great accident more likely can occur, and pipeline damping be designed to reduce this and ask
The generation of topic.
At present major part pipeline damping can tend to pipeline support, and the most not every pipeline is all had ready conditions use
Pipeline support solves the problem of damping, even if solving the problem of damping, expense the most costly, now can use pipeline
Tuned mass damper solves problems.Such as, the Chinese patent literature of application number 201420020559.6 discloses one
Planting pipeline tuned mass damper structure, the program devises a kind of tuned mass damper structure reducing pipe vibration, adopts
Be separable type inside and outside ring structure, whole outer shroud be can subdivision structure, by two half identical and symmetrical outer shrouds with two screws
Synthesize whole outer shroud；Whole internal ring be also can subdivision structure, by two half identical and symmetrical internal ring with two other screw synthesis whole
Internal ring；Between whole outer shroud and whole internal ring, circumference is symmetrically installed multiple spring and the antivibrator identical with number springs, whole internal ring
Internal diameter be less than the external diameter of held vibration damping pipeline.Although such scheme is to a certain degree solving the problem of pipeline damping,
But can be only applied to the pipeline that caliber is constant, and use inner and outer ring subdivision structure, it is the most convenient to dismount, and internal ring and pipeline directly connect
Touch, it may appear that stress is concentrated.
Summary of the invention
The purpose of this utility model is to provide a kind of convenient diameter-variable pipe tuned mass damper structure.
The purpose of this utility model is achieved through the following technical solutions:
Convenient diameter-variable pipe tuned mass damper structure of the present utility model, its preferably detailed description of the invention is:
It is connected with each other, including three 120 ° of circular blocks, the ring-type fixed mechanism surrounded, each 120 ° of circular blocks set respectively
Having antivibrator, the screw rod of the rear end of described antivibrator is through the circular hole on described 120 ° of circular blocks and passes through a pair locking nut admittedly
Being scheduled on described 120 ° of circular blocks, the front end of described antivibrator connects the adjustable gripping sheet having arc, described adjustable gripping
The front arc of sheet is fixed with rubber sheet gasket.
The technical scheme that thered is provided by above-mentioned this utility model it can be seen that this utility model embodiment provide convenient variable
Footpath pipeline tuned mass damper structure, goes for the pipeline of different-diameter, it is achieved damping effect.And can reduce because of interior
Ring directly contacts with pipeline and causes stress to concentrate.

Detailed description of the invention
This utility model embodiment will be described in further detail below.
Convenient diameter-variable pipe tuned mass damper structure of the present utility model, its preferably detailed description of the invention is:
It is connected with each other, including three 120 ° of circular blocks, the ring-type fixed mechanism surrounded, each 120 ° of circular blocks set respectively
Having antivibrator, the screw rod of the rear end of described antivibrator is through the circular hole on described 120 ° of circular blocks and passes through a pair locking nut admittedly
Being scheduled on described 120 ° of circular blocks, the front end of described antivibrator connects the adjustable gripping sheet having arc, described adjustable gripping
The front arc of sheet is fixed with rubber sheet gasket.
The described rear arc stating adjustable gripping sheet is provided with two cylinders, and the rear end of two cylinders passes described 120 ° of circles
Guide hole on block.
In three 120 ° of circular blocks, three junction points each other, two of which junction point passes through pin-hinges, another
Individual junction point is connected by screw and bolt.
Convenient diameter-variable pipe tuned mass damper structure of the present utility model, goes for the pipe of different-diameter
Road, and can reduce and cause stress to concentrate because internal ring directly contacts with pipeline.Principle of the present utility model is:
Use 3 adjustable gripping sheets, by a pair locking nut, the position of regulation adjustable gripping sheet, make scalable
Clamp clip is fitted tightly on pipeline.Adjustable gripping sheet is fixed on antivibrator, and antivibrator is fixed on fixed mechanism.Pipeline
The laterally or longitudinally load born is delivered on antivibrator by adjustable gripping sheet, is then unloaded by antivibrator, completes
Whole damping.
This utility model has the advantage that
1, this utility model uses and is articulated and connected mode, and convenient disassembly is convenient for assembly；
2,3 adjustable gripping sheets of the novel employing of this experiment, in can clamping according to the diameter adjustment of held pipeline
Footpath, universality is higher；
