As shown in Figure 1, in this present embodiment, a kind of marine piping shock-damping structure of the present invention, be set to pipeline 2 with
Between the power-equipment 1 of ship, including the first elastic tube 3 and damping part, one end of the first elastic tube 3 and power-equipment 1 connect
It connects, the other end is connect with damping part, and the other end of damping part is connect with pipeline 2, and damping part includes being fixedly installed on first
Pedestal 41 and the second elastic tube 42 of the inner space for being set to pedestal 41 on plate.
By the way that the first elastic tube 3 is arranged between the power-equipment 1 and pipeline 2 of ship, the vibration of power-equipment 1 can avoid
On conduction to pipeline 2, the vibration of pipeline 2 is caused；Damping part is set above deck, and the second elastic tube is set inside it
42, it further can effectively completely cut off in the vibration and noise transmission to pipeline 2 of power-equipment 1 and cause the vibration and noise of pipeline 2
Conduction.
In a specific embodiment of the invention, pedestal 41 includes bracket 411, buffer unit 412 and connecting flange
413, bracket 411 is fixedly installed on deck, and connecting flange 413 is set to 411 top of bracket, 412 company of being set to of buffer unit
Between acting flange 413 and bracket 411, the second elastic tube 42 is arranged on connecting flange 413, bracket 411 be hollow structure, second
The one end of elastic tube 42 far from the first elastic tube 3 is connect by passing through inside bracket 411 with pipeline 2.
Specifically, buffer unit 412 is the spring assembly being sheathed on outside the second elastic tube 42.
By being arranged the connecting flange 413 that is sheathed on the second elastic tube 42 on pedestal 41, and connecting flange 413 with
Buffer unit 412 is set between bracket 411, further can prevent from shaking on the basis of 42 pairs of the second elastic tube isolation vibrated
It is dynamic to be transferred to the latter linked pipeline 2 of power-equipment 1, shock-damping structure is enhanced to the isolation capacity of conduct vibrations, avoids power
The vibration of equipment 1 is transmitted on pipeline 2, and pipeline 2 is caused to vibrate, and the vibrating noise that vibration is caused.
In another embodiment of the present invention, buffer unit 412 includes that multiple limits being set on bracket 411 are led
Bar and the spring for being sheathed on limit guide rod, corresponding limit guide rod offers through-hole on connecting flange 413, the both ends of spring respectively with
Bracket 411 is abutted with connecting flange 413.
Further, limit guide rod is symmetrical arranged around the second elastic tube 42.
By the way that multiple springs, and the movement by limit guide rod to spring are arranged between connecting flange 413 and bracket 411
Direction is limited, and the cushion effect of the buffer unit 412 between connecting flange 413 and bracket 411 can be effectively adjusted.In reality
In use process can by increase or decrease spring quantity change buffer unit 412 vibration frequency, further avoid by
When the vibration frequency of buffer unit 412 is close with the vibration frequency of power-equipment 1, buffer unit 412 and power-equipment 1 resonate
And lead to the vibration of pipeline 2.
In embodiments of the present invention, the rigidity of the first elastic tube 3 and the second elastic tube 42 is less than the rigid of buffer unit 412
Degree.
By the rigidity that the setting of the rigidity of the first elastic tube 3 and the second elastic tube 42 is less than to buffer unit 412, it is ensured that
First elastic tube 3 and the second elastic tube 42 can Free Transform offset the vibration of power-equipment 1, and reduce the whole shifting of pipeline 2
Position.
In embodiments of the present invention, connecting tube 5,5 material of connecting tube are provided between the first elastic tube 3 and the second elastic tube 42
Matter and pipeline 2 are consistent.
Further, connecting tube 5 is bridge piece, and the rigidity of connecting tube 5 is less than the rigidity of pipeline 2, the half of bridge piece
Diameter is 300mm-600mm.
By connecting tube 5 being arranged between the first elastic tube 3 and the second elastic tube 42, it can be achieved that deflecting to pipeline 2, with
And the vibration transmitting between the first elastic tube 3 and the second elastic tube 42 is avoided to act on.
In embodiments of the present invention, the first elastic tube 3 and the second elastic tube 42 use ripple identical with the material of pipeline 2
Pipe.
By using the first elastic tube 3 and the second elastic tube 42 of bellows fashion using the first elastic tube 3 and second
The elastic reaction of elastic tube 42 weakens vibration, and sets the first elastic tube 3 and the second elastic tube 42 to and pipeline 2
Material it is identical, can avoid the performance decline of pipeline 2 caused by the setting of the first elastic tube 3 and the second elastic tube 42.
In a preferred embodiment of the invention, pedestal 41 is movably arranged by mounting base on deck, is installed
Seat can be achieved along X, the reciprocating movement of Y direction.
Specifically, mounting base includes two the first sliding rails disposed in parallel, the first mounting base of sliding setting on the first sliding rail,
Two the second mounting bases of sliding setting in first mounting base, two the second mounting bases are parallel and interval is arranged, and the first mounting base is along X
Axis direction is mobile, and two the second mounting bases move along the y axis.
Further, spring assembly is provided between the first mounting base and the first sliding rail, the second mounting base is sliding with second
Spring is provided between rail.By distinguishing between the second mounting base and the second sliding rail between the first mounting base and the first sliding rail
Spring is installed, the reset after the first mounting base and the second mounting base are mobile is can be used to ensure that, guarantees the first mounting base and the second peace
Dress seat is always positioned at setting position, i.e. guarantee pedestal 41 is always positioned at installation site.
In other embodiments, the fit structure of sliding rail and mounting base can be also changed to sliding slot and sliding block fit structure or
The structure of the movement of the achievable mounting base such as guide rod and sliding block.
By the way that pedestal 41 to be set as to reciprocatingly move along X, Y direction, and resetted under the left and right of spring assembly, it can
Vibration is cut down by the movement of pedestal 41, vibration in the x, y direction is avoided to be transmitted to pipeline.Simultaneously because the first bullet
The setting of property pipe 3, the second elastic tube 42 and buffer unit 412, can cut down vibration along the vertical direction, be achieved in and set to power
Standby 1 vibration isolation avoids conducting to pipeline 2 vibration for causing pipeline 2, and reduces and vibrate brought noise.
