Abstract

The utility model discloses a special lifting tool for a wind generator variable-paddle cabinet, which comprises two C-shaped lifting hooks and a plurality of connecting rods arranged between the two C-shaped lifting hooks. The connecting rods are fixedly connected with the two C-shaped lifting hooks to form a lifting frame; lifting holes are arranged on cross bars on the upper sides of the C-shaped lifting hooks; and one end of each of cross bars on the lower sides of the C-shaped lifting hooks is connected with a connecting plate perpendicularly and fixedly. When in lifting, the connecting plates are fixedly connected with a supporting frame provided with a battery cabinet and an axial control cabinet by fastening parts. The special lifting tool is simple in structure and convenient in operation, and is safe and reliable. As the special lifting tool is not in interference with a hub, the battery cabinet, the axial control cabinet and supporting frame components can be lifted to mounting positions, the two cabinets can be mounted easily without manual assistance, parts of the two cabinets and other parts cannot be damaged in lifting, assembly precision of the parts is ensured, the special lifting tool is accurate in positioning and high in operating efficiency, and the labor intensity of workers is reduced greatly.

Description

Wind-driven generator pitching cabinet special hanger
Technical field
The utility model relates to a kind of wind-driven generator pitching cabinet, and especially a kind of wind-driven generator pitching cabinet special hanger belongs to lifting harness technical field.
Background technology
Aerogenerator is that wind energy is converted to the power machine that mechanical energy is transformed into electric energy again, and pitch-controlled system plays crucial effect as the outer shroud of wind power generator control system in the control of aerogenerator.The pitch-controlled wind-driven generator group is meant that whole blade around the rotation of blade center shaft, changes attack angle of blade in certain limit (general 0 °~90 °), is no more than the design allowed value so that regulate horsepower output.The displacement unit relatively is suitable for the low area operation of plateau density of air, has avoided after stall machine stagger angle is determined, it is low to generate electricity summer, and surpasses the problem of sending out winter.Generally adopt the feather technology in the Large-scale Wind Turbines.
Battery rack, axle control cabinet mounting means have two kinds in the pitch-controlled system of existing electric variable pitch aerogenerator, and the first is fixedly mounted on bracing frame on the wheel hub earlier, manually lift respectively then to become oar battery rack, axle control cabinet, and left-hand thread is installed on bracing frame.When adopting this mode to install, counter being attached on the bracing frame of fastening need of the installation of two cabinets, operation is extremely inconvenient, and needs 4~5 young and vigorous workmans just can lift battery rack, axle control cabinet, and labor strength is big.It two is after bracing frame is fixedly mounted on the wheel hub, hangs in to become oar battery rack, axle control cabinet from the wheel hub manhole, manually lifts battery rack again, an axle control cabinet is installed on the bracing frame.When adopting this mode to install, because battery rack, axle control do not have suitable Heave Here cashier's office in a shop, the lifting difficulty, after the lifting, owing to be easy to generate interference between suspender and wheel hub, battery rack, the lifting of axle control cabinet can not be put in place, still to rely on manpower to lift installation, and because of rotary space in the wheel hub is little, two cabinets lift wastes time and energy.Above-mentioned dual mode installing and locating is inaccurate, and inefficiency, also might damage when lifting into installation self and miscellaneous part be as becoming oar motor etc., and then influence assembly precision, simultaneously the bigger potential safety hazard of existence.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, the wind-driven generator pitching cabinet special hanger of safe ready, accurate positioning is installed.
The utility model is achieved by the following technical programs:
A kind of wind-driven generator pitching cabinet special hanger comprises two C shape suspension hooks, is separately positioned on two several pipe links between the C shape suspension hook, and described several pipe links and two C shape suspension hooks are fixedly connected into lifting frame.Described C shape hook upside cross bar is provided with hole for hoist, and C shape hook downside cross bar one end is connected with the connecting panel vertical fixing.During lifting, described connecting panel is captiveed joint with the bracing frame that battery rack, axle control cabinet are housed by fastener.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid wind-driven generator pitching cabinet special hanger, wherein said C shape hook upside cross bar one end is provided with transversely arranged a plurality of holes for hoist.
The utility model is simple in structure, and is easy to operate, safe and reliable.When battery rack, axle control cabinet are installed, earlier battery rack, axle are controlled the cabinet pad on sleeper, make the adapter plate of battery rack and axle control cabinet be in same plane, then bracing frame is moved from the bottom up, make battery rack and axle control cabinet be inserted in the bracing frame, and will connect battery rack with fastener and captive joint with bracing frame with the adapter plate of axle control cabinet and be integral, again the connecting panel of the utility model one end is captiveed joint with bracing frame.Under the lifting of hoisting crane,, that the attachment face of bracing frame and wheel hub is fastening with a plurality of screws by vertical the hanging in the wheel hub of bracket assembly of the utility model with battery rack, axle control cabinet and bracket assembly.Owing to can not produce interference between the utility model and wheel hub, battery rack, the axle control cabinet that is fixed in the bracing frame once can be lifted and puts in place, need not in the auxiliary wheel hub of can like a cork battery rack, axle control cabinet being packed into of manpower.Lift easy, safety, and accurate positioning, high efficiency, time saving and energy saving, greatly reduce working strength of workers.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
