Tensile Elastic Vibration Isolator

Abstract

The invention belongs to the field of vibration control and particularly relates to a tensile and elastic vibration isolator. The tensile and elastic vibration isolator comprises a top plate, a base plate and an elastic supporting component. The elastic supporting component comprises metal compression springs. The tensile and elastic vibration isolator further comprises a back pressure elastic component, a back pressure plate and a connecting rod. The bottom end of the connecting rod is fixedly connected with the base plate. A limiting piece of the back pressure elastic component is arranged on the top of the connecting rod. The top plate is internally provided with a back pressure groove, a back pressure circular bead or a back pressure cavity. The back pressure elastic component is arranged on the back pressure circular bead or in the limiting groove or the back pressure cavity through the limiting piece on the top of the connecting rod. The tensile and elastic supporting component is simple in structure, can bear downward pressure, can also bear upward tension, is high in vibration isolation efficiency and more stable and reliable in vibration isolation performance, can be widely applied to elastic vibration isolation foundation projects of various industrial rotation devices or rail transit vehicle operation and has wide market application prospects.

Description

technical field [0001] The invention belongs to the field of vibration control, in particular to a vibration isolation device, in particular to a tensile elastic vibration isolator that can be widely used for vibration isolation of rail floating slab track beds, equipment or equipment foundations, and the like. Background technique [0002] In recent years, with the continuous advancement of my country's industrial upgrading, various large-scale impact or rotary equipment are widely used in industrial production and commercial fields, such as various forging equipment, stamping equipment, nuclear power turbine generator sets, etc. At the same time, these The control of vibration and noise generated during the operation of equipment has also attracted people's attention. At present, in order to control this kind of vibration and noise problems, the technical principle of mass tuning is mostly used, and the vibration isolation system is composed of mass blocks and elastic compo...

AI Technical Summary

Problems solved by technology

Taking large-scale forging equipment as an example, when working, the forging working part will lift up immediately after impacting the workpiece. At this time, the impact on the workbench will be transmitted to the steel spring vibration isolator under the equipment. It does not act continuously on the workbench, so the steel spring vibration isolator will rebound immediately after being compressed and deformed, and because the existing steel spring vibration isolators generally cannot bear the upward pulling force, the steel spring vibration isolator may be caused by insufficient pressure. If the displacement is serious, the spring parts in the steel spring vibration isolator will jump when they rebound to exceed their free height. When the impact is very strong, the jumping range of the spring parts may be too large. In the case of falling out and dumping, this situation will cause the steel spring vibration isolator to lose part or even all of its elastic support capacity, affecting the normal use and operation safety of the equipment

[0003] Similarly, the short prefabricated slab floating track bed also has such problems. For example, when the rail vehicle enters from one end, due to the short prefabricated slab's own weight is relatively light, there will be a seesaw effect, that is, the other end of the short prefabricated slab has an upward If the tilting tendency cannot be effectively controlled, the steel spring vibration isolator on the tilted side of the short prefabricated slab will have insufficient pressure, which will easily cause the short prefabricated slab to shift or the elastic elements in the steel spring vibration isolator to jump out Problems such as overturning or overturning will bring safety hazards to daily operations

[0004] In addition, the steel spring vibration isolation device of ship power equipment also has such problems. When encountering strong sea waves, the ship will shake violently, and the ship power equipment will inevitably shake together. In severe cases, some steel spring vibration isolation devices The borne load may be completely released, and the spring parts may jump out or fall easily, causing the vibration isolation system to fail, and even endangering the safety of the ship's power equipment
