Description
Technical field
The present invention relates to ship exhaust pipe rain-proof cap flexible type vibration insulation structures.
Background technique
Host diesel engine and auxiliary diesel engine on ship can generate exhaust gas at work, these exhaust gas all will be from ship
Exhaust pipe be expelled to atmosphere, due to diesel engine generate exhaust gas temperature it is very high, the end of exhaust pipe be easy to produce heat it is swollen
Bulging deformation not can guarantee the work safety of exhaust pipe to damage exhaust pipe；And when diesel engine generation exhaust gas, the exhaust gas of formation
There is biggish impact force, and there is strong wind at sea, leads to Ship Swaying, the collective effect of impact force and wind-force through exhaust gas is held
The hydrosphere that encloses easily led on rainhat and deck in exhaust pipe end collides, and generates biggish vibration and noise, seriously
Influence the comfort in the regions such as driving, inhabitation.To solve the above problems, it is generally necessary to the end of exhaust pipe is fixed, so
And exhaust pipe is line style steel object, the direction expanded after heated is axial, if exhaust pipe end is fixed, can be led
Exhaust pipe axial freedom is caused to be limited, the expansion length of exhaust pipe axial direction will be discharged by exhaust pipe bending, to cause
Exhaust pipe bending deformation further influences the normal work of exhaust pipe.
Summary of the invention
The present invention is intended to provide one kind can either effectively prevent exhaust pipe to damage because of thermal expansion, and can effectively vibration damping drop
The ship exhaust pipe rain-proof cap flexible type vibration insulation structure made an uproar.
A kind of ship exhaust pipe rain-proof cap flexible type vibration insulation structure of the present invention, including be vertically arranged in rainhat with
The carrying bolt between hydrosphere is enclosed, one end connection of carrying bolt is arranged with above deck, on carrying bolt can be with respect to its sliding
Elastic damping block subtract below elastic damping block and in being provided with locking nut on carrying bolt in locking nut and elasticity
Between vibration block and in being arranged with pressure spring on carrying bolt, pressure spring one end is against on elastic damping block end face, and elastic damping block is another
One end face is pushed against on the bolt end surface of carrying bolt, and the pressure spring other end is against on locking nut end face.
A kind of ship exhaust pipe rain-proof cap flexible type vibration insulation structure of the present invention, in rainhat by larger radial force
When, rainhat, which moves radially, hits elastic damping block, and hydrosphere will be enclosed by elastic damping block and separated with rainhat, therefore, rain-proof
Cap will not directly with enclose hydrosphere bump against, and elastic damping block because its have elasticity, therefore can by rainhat hit effect
Power effectively absorbs, and avoids generating vibration and noise because hitting, and effectively increases and the comfortable of regions such as drives, lives on ship
Property；And since elastic damping block carrying bolt can slide relatively, meanwhile, pressure spring again holds out against elastic damping block in carrying bolt
Bolt end surface on, therefore, in radial force of the elastic damping block by rainhat, pass through the micro vertical shifting of elastic damping block
It is dynamic to squeeze pressure spring, can absorption rainhat by a larger margin impact kinetic energy, so that the cooperation by elastic damping block and pressure spring reaches
To flexible constraint rainhat and the purpose for enclosing hydrosphere diametrically freedom degree, the noise generated because the two is directly hit is avoided
And vibration；Due to flexible type vibration insulation structure not with rainhat and enclose hydrosphere and be directly connected to, only constrain rainhat radial
Movement, for rainhat and the axial freedom for enclosing hydrosphere without any constraint, therefore can sufficiently discharge exhaust outlet end axis
To thermal expansion deformation, avoid exhaust pipe axial thermal expansion from passing through pipeline bending to discharge, effectively prevent conduit failure, ensure that
The work safety of exhaust pipe；In addition, the compression degree of pressure spring is adjusted, to provide elastic damping by adjusting lock nut
The enough support strengths of block compensate its deformation force generated because being hit by rainhat, and elastic damping block is avoided to hit because long-term
It deforms and damages, extend the service life of elastic damping block；In addition, taking carrying bolt as support member, avoid to branch
The processing of support part part, reduces costs.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the top view of elastic damping block.
Specific embodiment
A kind of ship exhaust pipe rain-proof cap flexible type vibration insulation structure, as shown in Figure 1, include be vertically arranged in rainhat 1 with
The carrying bolt 3 between hydrosphere 2 is enclosed, one end of carrying bolt 3 is connected on deck 4, and being arranged on carrying bolt 3 can be with respect to it
The elastic damping block 5 of sliding, below elastic damping block 5 and in being provided with locking nut 6 on carrying bolt 3, in locking nut 6
Between elastic damping block 5 and in being arranged with pressure spring 7 on carrying bolt 3,7 one end of pressure spring is against on 5 end face of elastic damping block, will
5 other end of elastic damping block is pushed against on the bolt end surface of carrying bolt 3, and 7 other end of pressure spring is against 6 end face of locking nut
On.The material of the elastic damping block 5 is rubber.
As shown in Fig. 2, vertical chamfering 8 is provided on the side wall of the elastic damping block 5, since rainhat 1 is cyclic annular
, therefore, chamfering 8 is set on the side wall towards rainhat 1 of elastic damping block 5, elastic damping block 5 and rainhat can be made
1 side wall contact is more bonded.
Between elastic damping block 5 and the bolt head of carrying bolt 3 and between elastic damping block 5 and pressure spring 7 respectively
It is provided with plain washer 9, by the way that plain washer 9 is arranged, to increase the bolt of elastic damping block 5 and 7 end face of pressure spring and carrying bolt 3
The contact area of end surface makes pressure spring 7 provide the support force of elastic damping block 5 more evenly, avoids answering because of the small generation of contact area
Power is concentrated and damages elastic damping block 5.
Base nut 10 is fixed on deck 4, the bottom of carrying bolt 3 is tightened in base nut 10, will support spiral shell
Bolt 3 is connected on deck 4, is connected by setting base nut 10, can carrying bolt 3 easy to disassemble.
