Abstract
The utility model discloses a vibration isolation pad. The vibration isolation pad is composed of bearing steel plates, a connecting structure, damping polystyrene foam and a palm fiber elastic layer. An inner gap step structure and an outer extension step structure are arranged on the peripheral edge of each bearing steel plate respectively, and the bearing steel plates adhere to the upper surface of the palm fiber elastic layer through the damping polystyrene foam. Fastening bolt holes are formed in the outer extension step structure on the periphery of each bearing steel plate. The palm fiber elastic layer is formed by machining natural palm fiber and coconut fiber, the upper surface of the palm fiber elastic layer is a plane, and the lower face of the palm fiber elastic layer is corrugated. In order to improve the load borne by the vibration isolation pad, the bearing steel plates are inlaid in one another through the inner gap step structures and the outer extension step structures and connected into a whole through fastening bolts, and thus the bearing area of the vibration isolation pad is enlarged. In order to reduce the natural frequency of vibration of the vibration isolation pad, two or more vibration isolation pads are connected in series for use. The vibration isolation pad is made of novel environment-friendly materials low in energy consumption and rich in source and has the advantages of being high in compressive strength and weather resistance, simple in construction technology and convenient to install.
Description
Technical field
The utility model relates to a kind of noise control technique, especially can solve the vibration isolator of Vibration propagation.
Background technique
Along with the attention to Environmental Noise Influence, the application of vibration isolator is increasingly extensive, and existing vibration isolator uses rubber vibration insulating pad, and still, the natural frequency of rubber damper is higher, and the damping efficiency of low frequency configuration noise is lower.Meanwhile, rubber damper is poor to working environment adaptability, is subject to the impact of the factors such as temperature, ozone, service condition, easily produces performance variation and aging, therefore will make regular check on, to change in time.Rubber material more uses chemosynthesis to form at present.Current, strengthen energy-saving and emission-reduction work, the idea of reply Global climate change is rooted in the hearts of the people, and noise control, as environment-friendly engineering, should take the lead in carrying out energy-saving and emission-reduction theory.To select as much as possible to there is low power consuming, source is abundant, the environment-friendly novel material of recoverable, to the generation of the resource consumption in minimizing process and waste.
Summary of the invention
In order to overcome rubber damper to the poor deficiency of working environment adaptability.The utility model provides a kind of vibration isolator, the environment-friendly novel material that this vibration isolator uses low power consuming, originates abundant, and damping efficiency is high.
The utility model solves the technological scheme that its technical problem adopts: a kind of vibration isolator, is made up of force-bearing steel plate and linkage structure, damping foamed glue, monofilament elasitic layer.Described force-bearing steel plate edge is respectively interior scarce rank shape and extension rank shape structure, and force-bearing steel plate uses foaming damping glue and adhesion above monofilament elasitic layer.Use the adhesion of damping foamed glue to be both conducive to reduce the vibration transmission of force-bearing steel plate, be also conducive to improve vibration isolator sound insulation property.Described force-bearing steel plate surrounding is, in the shape structure of extension rank, fastening bolt holes is set.Above described monofilament elasitic layer, being plane, is ripple moulding below.Below monofilament elasitic layer, can improve the elasticity of vibration isolator for ripple moulding, reduce the natural frequency of vibration.Monofilament elastic insert is take crude palm fiber, coir as framework material, containing sugar and protein, is difficult for mouldy and is damaged by worms, and is to have that low power consuming, source are abundant, the environment-friendly novel material of recoverable.According to aerodynamic principle, monofilament is arranged in to space reticular structure and forms thousands upon thousands " plant spring ", adopt adhesive make it inter-adhesive or form the fine cube of whippy palm fibre by other Placement, elastic force is sustained, its natural frequency of vibration is low, and anti-weight bearing power is far above traditional elastic cushioning material.The load bearing for improving vibration isolator, will inlay by interior scarce rank shape, extension rank shape between force-bearing steel plate, uses clamping bolt to join together, expands the loaded area of vibration isolator.Reduce the natural frequency of vibration
0, the rigidity of minimizing vibration isolator, to reach the transmission that reduces vibration.
For reducing the natural frequency of vibration of vibration isolator, by two and above vibration isolator stack series connection use.When vibration isolator stack series connection, the upper and lower ripple moulding of monofilament elasitic layer should intersect.
The beneficial effects of the utility model are, the environment-friendly novel material of use low power consuming, originating abundant, and compressive strength is high, and weather resisteant is strong, and construction process is simple, easy for installation, and price is relatively cheap.
