Embodiment
In order to illustrate the technical solution of the utility model and technique effect, below in conjunction with drawings and the specific embodiments, the utility model is described further.
As shown in Figure 1 and Figure 2, the thimble structure of a kind of adjustable inhibition naval vessel pipeline vibration noise, but but comprise bolt 1 shake inner ring 2 shake outer ring 3, handle 4, cylindroid helicalcoil extension spring 5 and bracket component.
In the present embodiment, described bolt 1 adopts the steel hex head bolt with certain length, is vertically arranged on TOP top.But the described inner ring 2 that shakes wraps in pipeline 10 outer surfaces, preferably adopts the perforation vibration isolator of foam silicone rubber material.But the described inner ring 2 that shakes wraps up after pipeline one circle, in pipeline 10 top closures, but does not link, but upwards draws in, and the surplus circle body upwards being drawn in is connected with bolt 1 bottom.If the direction that pipeline 10 extends is for radially, but as described in the inner ring 2 width diametrically length of comparing with the diameter of bolt 1 of shaking, but can utilize support connecting piece to connect shake circle body and the bolt 1 of inner ring 2, but the top circle body of the inner ring 2 that makes to shake is upwards lifted or discharge, and avoids local pressure downwards by entirety.
But but the described outer ring 3 that shakes is arranged on pipeline 10 and the periphery of the inner ring 2 that shakes, but the inside filled polyurethane foamed plastics interlayer of wall is enclosed in the outer ring 3 that shakes, and outer casing is aluminum alloy material, but and 3 tops, outer ring that shake be provided with and hold the through hole that bolt 1 key passes through.
Described handle 4 tail ends are provided with the screw (female groove) matching with bolt 1 outside thread, and head end is holding part, i.e. force application location.Handle 4 is arranged on bolt 1 by described screw, but handle 4 belows are also provided with and are bonded in 3 tops, outer ring that shake, and middle part is provided with and holds bolt 1 by the steel bed course 8 of circular hole.
Described cylindroid helicalcoil extension spring 5 is provided with 5 altogether, when initial installation, but but be evenly distributed in the inner ring 2 and shaking between outer ring 3 of shaking, but and cylindroid helicalcoil extension spring 5 one end be connected with outer ring 3 internal surfaces that shake by vibration isolator 9, but one end is connected with inner ring 2 outer surfaces that shake.
Described bracket component comprises master bracket 6 and sub-stent 7.Described master bracket 6 is provided with 2, adopt aluminum alloy material to make, and surface is coated with rubber coating, vertical bolt 1 both sides that are distributed in.Master bracket 6 Yu Yizhen outer ring, top 3 internal surfaces are fixedly connected with, and tail end is provided with to the spherical portion of the bolt 1 lateral deviation heart, but draw surplus circle body in the position upwards of inner ring 2 that shakes, but the circle body of the inner ring 2 coated pipelines 10 that make to shake is close to pipeline 10.Described sub-stent 7 is also provided with 2, is symmetricly set on bolt 1 both sides, and sub-stent 7 is obliquely installed, and Yu Yizhen outer ring, top 3 internal surfaces connect, and tail end and master bracket connect as one, and form triangle robust structure with master bracket 6.
Consider that but the inner ring 2 that shakes has certain width diametrically, many pack supports assembly is set on can be radially.
When ship's fitting work, pipe-line system produces noise and vibration, but the inner ring 2 that shakes will be reacted and suppress vibration in the very first time; Spiral stretching spring 5 plays the effect that absorbs vibrational excitation on the one hand, but residual vibration excitation can be conducted to the outer ring 3 that shakes on the other hand, but the outer ring 3 that shakes will suppress vibrating noise to the full extent; Master bracket 6 and sub-stent 7 have also played certain inhibition vibrating effect when but inner ring 2 is shaken in holder quality and gathering, thereby this device reduces the vibration of pipe-line system and hull structure, reaches the effect of good inhibition vibrating noise.
In order to adapt to working environment complicated and changeable, this device is adjustable, to be applicable to the pipeline of different-diameter in certain limit.
When initial installation, between the bottom of bolt 1 and pipeline 10, leave certain distance.When pipeline 10 diameters are when larger, left hand fixing bolt 1 top, bolt 1 entirety is maintained static, the right hand handle 4 that turns clockwise, handle 4 is moved vertically upward on bolt 1, displacement distance is depending on pipeline 10 diameters, now between handle 4 and steel bed course 8, there is blank nut-stem, left hand is pinned the bolt 1 top application of force vertically downward, bolt 1 and handle 4 entirety are moved vertically downward, until handle 4 fits with steel bed course 8, but the inner ring 2 that shakes being fixedly connected with bolt 1 tail end also by discharging a part of circle body in master bracket 6 simultaneously, but the last adaptive degree according to shake inner ring 2 and pipeline 10 is finely tuned, but the inner ring 2 that makes to shake is tightly overlying on pipeline 10 outer surfaces, reach use standard.When pipeline 10 diameters hour, left hand fixing bolt 1 top, the right hand is rotated counterclockwise handle 4, make screw rod 1 realize vertical moving up by the mutual extruding of handle 4 tail ends and steel bed course 8, thereby but bolt 1 tail end drives the inner ring 2 that shakes to receive to support 6, but the last adaptive degree according to shake inner ring 2 and pipeline 10 is finely tuned, but the inner ring 2 that makes to shake is tightly overlying on pipeline 10 outer surfaces, reaches use standard.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand, the utility model is not restricted to the described embodiments, that in above-described embodiment and specification, describes just illustrates principle of the present utility model, is not departing under the prerequisite of the utility model spirit and scope, and the utility model also has various changes and modifications.The claimed scope of the utility model is defined by appending claims, specification and equivalent thereof.
