Abstract
The utility model discloses a wheel hub overhauling structure of a megawatt level wind generating set, and belongs to the technical field of the wind generating set. A part of a wheel hub close to a main shaft is provided with a first hanging hole; a variable pitch propeller speed reducer is arranged in vertical direction of the first hanging hole; the front ends of a flow guide housing and a cabin housing are provided with a second hanging hole and a hanging port corresponding to a variable pitch propeller system respectively; and a crane is arranged in a cabin. According to the wheel hub overhauling structure, by arranging the hanging holes or the hanging ports at the front ends of the wheel hub, the flow guide housing and the cabin housing, lifting is performed through a crane in the cabin when the wheel hub overhauling structure system fails. The problem of difficulty in replacement during failure of a megawatt level wind mill wheel hub component is solved. The wheel hub overhauling structure has higher efficiency and safety during trouble removal of a wind mill.
Description
Technical field
The utility model belongs to the generator set technical field, particularly relates to a kind of MW class wind turbine group wheel hub maintenance structure.
Technical background
Fast development along with wind generating technology; The also existing small-power of the power of wind power generating set develops to MW class; Mostly what occur in the market is the unit of 1MW to 3 MW class, along with a lot of more powerful units of the development of offshore wind farm also among the research and development plan of each wind-powered electricity generation enterprise.Along with the increase of the power of the assembling unit, also will be become greatly by the specification of component, this brings problems with regard to the maintenance of giving the big group of motors of wind-force, and single parts have reached several tons, can't carry, install and change only according to manpower.The maintenance of wind energy conversion system at present all is furnished with telpher usually in the cabin from ground to the cat head; Be convenient to each part replacement of cabin; But because the particularity of wind energy conversion system wheel hub structure and transmission; Passage from the wheel hub to the cabin is very limited; Parts in the wheel hub (such as becoming oar motor, speed reducer etc.) are if fault needs whole wheel hub is hung the replacing trouble unit or through manpower trouble unit is delivered to the cabin usually, and which kind of method all will spend a large amount of manpower and materials and time, have a strong impact on working efficiency.
Summary of the invention
To the technical problem of above-mentioned existence, the utility model provides a kind of MW class wind turbine group wheel hub maintenance structure, is convenient to change the wheel hub trouble unit.
To achieve these goals, the technological scheme of the utility model employing is:
The utility model has first erection opening at wheel hub near the position of main shaft; Variable pitch speed reducer is arranged on the Vertical direction of first erection opening; Be respectively equipped with second erection opening and lifting mouth at the corresponding pitch-controlled system with the engine room cover front end of air guide sleeve, crane is arranged in the cabin.
The beneficial effect of the utility model is:
The utility model is through erection opening or lifting mouth are set at wheel hub, air guide sleeve and engine room cover front end, when pitch-controlled system breaks down, through the crane lifting in the cabin.The problem that has been difficult to change when having solved MW class wind energy conversion system wheelboss part fault.It is more efficient, safer in fan trouble is got rid of.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. first erection opening, 2. pitch-controlled system, 3. wheel hub, 4. crane, 5. cabin, 6. air guide sleeve, 7. lifting mouthful, 8. second erection opening.
Embodiment
According to accompanying drawing and embodiment the utility model is elaborated below.
Embodiment: as shown in Figure 1; The utility model has first erection opening 1 at wheel hub 3 near the position of main shaft; Variable pitch speed reducer is arranged on the Vertical direction of first erection opening 1; Be respectively equipped with second erection opening 8 and lifting mouth 7 at air guide sleeve 6 corresponding pitch-controlled systems 2 with the engine room cover front end, crane 4 is arranged in the cabin 5.When wheel hub 3 inner pieces break down the needs replacing; Open cabin 5 front ends lifting mouth 7 and second erection opening of air guide sleeve 6 and first erection opening 1 on the wheel hub 3; Launch crane 4, put down suspension hook and trouble unit is fixed on the suspension hook, unclamp the cable and the clamping bolt of trouble unit then, it is accessed wheel hub 3 be put into cabin 5; Be put into ground by cabin crane 4, according to opposite step new parts be installed in the wheel hub 3 again.
