Embodiment one
Describe in conjunction with Fig. 1 to Fig. 5.Fig. 1 is the damping trustship plan view in the present embodiment one; Fig. 2 is the left view of Fig. 1; Fig. 3 is the enlarged view at I place in Fig. 1, and magnification ratio is 8:1; Fig. 4 is the enlarged view at II place in Fig. 1, and magnification ratio is 4:1; Fig. 5 is the enlarged view at III place in Fig. 1, and magnification ratio is 2:1.
Rubber plate mechanism comprises: rubber plate assembly and two conduits 10; The rubber plate assembly comprises rubber plate 11 and enclosed mass 12.Enclosed mass 12 comprises three that are connected as a single entity: front, sole piece and rear; Rubber plate 11 is arranged in enclosed mass 12; Described rubber plate assembly, its left part and right part are respectively offered a mounting hole, and a conduit 10 is set in each mounting hole.In the rubber plate assembly, what play a major role is rubber plate 11, and rubber plate 11 can play the texts such as damping well, but can work for a long time, reliably for rubber plate 11, prevents breakage, breaks, is out of shape etc., has used enclosed mass 12.
In the adaptable various vibration damping pipe supports of the utility model technology, left and right sides spring pressure mechanism is symmetrically arranged.Left side spring pressure mechanism and right side spring pressure mechanism, each spring pressure mechanism all comprise: the first spring 13, and spring box 14, the first pressing plates 15, the first connecting rod 16 of screw thread is offered on top; The bottom of first connecting rod 16 is fixedly connected with the first pressing plate 15.First connecting rod 16 by under pass the movable span of the first spring 13 and spring box 14 cappings up, further, the first pressing plate 15 elasticity of the bottom of the first spring 13 and first connecting rod 16 bottoms offset, the capping elasticity of the top of the first spring 13 and spring box 14 offsets; The bottom of spring box 14 is fixedly connected with base plate 7.
The rubber plate assembly applies the elastic pressure of damping downwards, in addition, the spring on both sides also applies elastic pressure downwards by the two ends of rubber plate assembly, namely say, when pipeline 1 has the trend that moves up, it both had been subject to the restriction of rubber plate assembly, also be subject to the spring restriction on both sides, and these two downward restraints was flexible.Single rubber plate assembly, its best cushioning ability has certain frequency range; Single paired spring, its best cushioning ability also has certain frequency range; Single paired buffer stopper, its best cushioning ability is equally also to have certain frequency range; Aforementioned three frequency ranges are all not identical, but they are combined in the utility model, and it is common, best cushioning ability stack just has very large frequency range, can be avoided or reduce to the vibrations of vibrations, the particularly above-below direction of pipeline 1.Also have, the product versatility is good, goes for being subjected to the pipeline of all directions shaking force.
Also have, in the present embodiment, buffer stopper is inlayed vibration-absorptive material by hardware and is formed.
In the situation that some is special, can all add snubber block at the undersetting four direction, to realize special, good damping effect.
The conduit 10 in rubber plate assembly mounting hole is passed on the top of first connecting rod 16, the top of first connecting rod 16 nut assembly of packing into.If there is no conduit 10, glutinous continuous cropping use may can occur with rubber plate in moment in first connecting rod 16, the effect of damping is reduced, and long-term work causes rubber plate damaged.
Nut assembly, it the most simply configures is that a place only uses a nut, this also is fine, but its technique effect is not good.In order to reach technique effect preferably, when design, configuration, the one, can increase pad, can prevent so after long-term work that rubber plate is damaged, the downward depression of nut, the 2nd, can increase the anti-loosening part that prevents nut loosening.About anti-loosening part, the most simply have, increase again a nut and an elastic washer on the basis of a nut of place use, make two stressed pressings of the elastic washer between nut, so can prevent from well becoming flexible; Also have, as shown in Figure 1, the increase label is 35 round nut, to play the effect of loosening retaining.
Embodiment two
Describe in conjunction with Fig. 6 and Fig. 7.
Different from the situation in embodiment one, in the present embodiment, spring is positioned at the upside of rubber plate assembly, and does not use spring box, sees the following description and explanation for details.
Rubber plate mechanism comprises: rubber plate assembly and two conduits 10.The rubber plate assembly comprises the three who arranges from top to bottom: upper plate 17, rubber plate 11, and lower plate 18.In the rubber plate assembly, what play a major role is rubber plate 11, but for rubber plate 11 can be for a long time, work reliably, prevent breakage, break, be out of shape etc., used upper plate 17 and lower plate 18.The left part of rubber plate assembly and right part are respectively offered a mounting hole, and a conduit 10 is set in each mounting hole; The effect of conduit 10 has: avoid second connecting rod 21 can glutinous continuous cropping use occur with rubber plate in moment, keep the technique effect of damping, prevent from causing in long-term work rubber plate damaged.On structure, the bottom of second connecting rod 21 is fixedly connected with base plate 7; The top of second connecting rod 21 is first passed the conduit 10 in rubber plate assembly mounting hole, then is passed the second spring 19, then passes the central hole of the second pressing plate 20; The top of second connecting rod 21 nut assembly of packing into; Further, upper plate 17 elasticity in the bottom of the second spring 19 and rubber plate assembly offset, and the top of the second spring 19 and the second pressing plate 20 elasticity offset.
Vibration damping pipe support in the present embodiment two, the rubber plate assembly applies the elastic pressure of damping downwards, in addition, the spring on both sides also applies elastic pressure downwards by the two ends of rubber plate assembly, namely say, when pipeline 1 had the trend that moves up, it both had been subject to the restriction of rubber plate assembly, also be subject to the spring restriction on both sides, and these two downward restraints are flexible.
Rubber plate assembly, the second paired spring 19, paired buffer stopper,
This three is combined in the utility model, and it is common, best cushioning ability stack just has very large frequency range; So, can in very large frequency range, make the vibrations of the vibrations of pipeline 1, particularly above-below direction be avoided or reduce.
