Abstract
The utility model discloses a platform damping structure which comprises a welded riser, a welded section steel and a platform plate fixed on the welded riser and the welded section steel; the riser is fixed with the tower wall; a layer first rubber plate is adhered between the platform plate and the riser; a layer second rubber plate is adhered between the platform plate and the section steel. In the platform damping structure, rubber plates are respectively adhered between the platform plate and the riser, and between the platform plate and the section steel, and fixed through fastening pieces; the vibration is reduced through the damping generated by the relative movement friction between the rubber and the riser, and between the rubber and the section steel; meanwhile, the noise is reduced.
Description
Technical field
The utility model relates to wind power generating set, relates in particular to a kind of platform vibration damping structure.
Technical background
Along with the maximization of blower fan, its pylon also uprises thereupon, and the platform in the pylon also increases, because in the time of fan operation, have bigger vibration, and pylon is a steel structure body, noise is quite big, how to reduce vibration, and reducing noise is the utility model problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of platform vibration damping structure is provided, and it can reduce vibration effectively, reduces noise.
The technological scheme that realizes above-mentioned purpose is: a kind of platform vibration damping structure, the lug and the shaped steel that comprise welding, and be fixed in the lug of welding and the landing slab on the shaped steel, lug and tower wall are fixed, wherein, also post one deck first rubber plate between described landing slab and the lug, also post one deck second rubber plate between described landing slab and the shaped steel.
Above-mentioned platform vibration damping structure wherein, comprises that also first fastening piece that passes landing slab, first rubber plate and lug is with fastening with landing slab and lug.
Above-mentioned platform vibration damping structure wherein, comprises that also two pass second fastening piece of landing slab, second rubber plate and shaped steel so that landing slab and shaped steel is fastening.
Above-mentioned platform vibration damping structure, wherein, the thickness of described first rubber plate and second rubber plate is 2mm.
The beneficial effects of the utility model are: paste one deck rubber plate between the landing slab of the utility model tower and lug, the shaped steel, fix with fastening piece again, by rubber and lug, the fricative damping of shaped steel relative movement, reduced vibration, also reduced noise simultaneously.
