Abstract
The utility model relates to the technical field of wind generators, in particular to a hydraulic support device arranged between a gearbox and a base of a large power generator group for shock absorption connection. A hydraulic support of the hydraulic device is connected with the gearbox, and the bottom of the hydraulic support is fixed on the upper end face of a welded support frame through screw bolts. The lower end face of the welded support frame is fixed on the base through bolts. Each hydraulic support is provided with two hydraulic pistons, and hydraulic lines are connected to form an enclosed hydraulic circuit in a structural form of a U-shaped pipe principle. The hydraulic support device can perfectly connect the gearbox and the base, and is simple in structure, high in strength and convenient to construct. The hydraulic support device overcomes the defect that an existing connection device is complicated in structure, large in appearance size, large in weight and inconvenient to install.
Description
Technical field:
The utility model relates to a kind of technical field of wind power generator, is used for the hydraulic support device that damping is connected between particularly a kind of gear-box of high-power wind-driven generator group and the base.
Background technique:
Along with the development of international wind-power electricity generation industry, large-scale offshore wind generating group is subjected to the concern of domestic and international relevant industries more and more.Wind energy on the sea has aboundresources, turbulence intensity is little, wind shear is little, do not take advantage such as limited land resources, and the development of marine wind field is an inevitable trend.Offshore wind turbine all is based on 3MW and above type, because offshore wind turbine operating mode complexity, running environment are abominable, this fan especially gear-box of high-power blower brings very big vibration, load such as reverses, and has seriously influenced the life-span of gear-box and the stability of unit.
Present domestic most of blower fan manufacturing firm adopts is that the elastic torsion bar supports or the Placement of elastic sleeve, the blower fan sector application at sea of elastic torsion bar supporting structure is more, but its complex structure, boundary dimension is big, weight is big, because the base inner space is limited, so bring very big inconvenience to installment work; The elastic sleeve major applications is in 1.5MW and following land type, and its damping property and structural strength can not satisfy the designing requirement of high-power offshore wind turbine.This shows, be badly in need of a kind of novel structural type and supporting way at marine 3MW and above type, to satisfy the service condition of special operation condition, particular surroundings.
The model utility content:
The technical problems to be solved in the utility model provides a kind of blower fan gear-box hydraulic support device, and this device realized and can well gear-box and base have been linked together, and is simple in structure, intensity height, easy construction.The deficiency that overcome existing connection set complex structure, boundary dimension is big, weight is big, installation is inconvenient.
Technical solution adopted in the utility model is: a kind of blower fan gear-box hydraulic support device, form by base, hydraulic pressure support, hydraulic line, gear-box and welding supporting frame; The hydraulic pressure support and connection are to gear-box, the hydraulic pressure support base is fixed on the upper-end surface of welding supporting frame by double-screw bolt, the welding supporting frame the lower end surface by bolt to base, each hydraulic pressure supports all two hydraulic pistons, connect into the oil hydraulic circuit of sealing by hydraulic line, form the structural type of " U " type pipe principle.
The beneficial effects of the utility model are: the utility model is owing to adopted hydraulic pressure to support " U " type pipe principle and reliable welding supporting frame Connecting format, thereby the vibration and the torsional load that can absorb effectively and gear-box be produced when slowing down fan operation, prolong the working life of gear-box effectively, guarantee that blower fan normally, work reposefully; Hydraulic pressure supports " U " type of employing pipe hydraulic principle, has advantages such as support is steady, non-maintaining, reliable in structure, long service life; The welding supporting frame adopts the hollow cavity body structure of steel plate welding, has rational in infrastructure, advantages such as intensity is high, easy construction.In addition, easy for installation, the reliable in structure of the utility model has good detachability and interchangeability.
