The invention has the beneficial effects as follows: but wind generating set engine room that should on-site maintenance operation cabin two side plates are launched around the inferior horn hinge, make cabin area change twice, the requirement of enough maintenance operatioies significantly reduces the maintenance cost of wind power generating set; Set up the swing arm hoist, for safeguarding and the installation exercise application, set up the cabin seat assembly, the support hoist that has improved the tower masthead fills the tilting moment that produces when hanging, and uses more safe and reliable.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
But accompanying drawing 1 is looked schematic representation for the master of the wind generating set engine room of the present invention's on-site maintenance operation.
But accompanying drawing 2 is the schematic top plan view of the wind generating set engine room of the present invention's on-site maintenance operation.
Accompanying drawing 3 is the A-A cross-sectional schematic among Fig. 1.
Among the figure, 1 gear-box, 2 hoists, 3 cabin front shrouds, 4 pull bars, 5 hinge axis front shrouds, 6 cabin seat assemblies, 7 cabin seat cylinders, 8 cabin seat axle sleeves, 9 driftage lower bearings, 10 brake discs, 11 nacelle chassis, 12 driftage small gears, 13 driftage gearwheels, 14 driftage upper bearing (metal)s, 15 generators, 16 Electric Appliance Cabinets, 17 hinge axis back covers, 18 right sideboards, 19 oil cylinders, 20 cabin back covers, 21 fastener holes, 22 left sideboards, 23 hinge axis, 24 cabins.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.But be somebody's turn to do the wind generating set engine room of on-site maintenance operation, comprise cabin 24, cabin 24 is provided with gear-box 1, generator 15 and Electric Appliance Cabinet 16, it is characterized in that: 24 left and right sides, cabin are provided with the deployable left sideboard of setting level 22 and right sideboard 18, cabin 24 front ends are provided with hoist 2, and nacelle chassis 11 downsides in cabin 24 are provided with cabin seat assembly 6.Described left sideboard 22 is connected with pull bar 4 and oil cylinder 19 respectively with right sideboard 18, left sideboard 22, right sideboard 18 1 ends are connected by hinge axis 23 with nacelle chassis 11, left sideboard 22, right sideboard 18 the other ends are the integrated top board that vertically is connected with respectively, described top board is broken as two halves by the center, two halves top board joint is provided with corresponding fastener hole 21, and described hinge axis 23 rear and front ends are respectively equipped with hinge axis front shroud 5 and hinge axis back cover 17.Described cabin seat assembly 6 comprises that cabin seat cylinder 7, cabin seat axle sleeve 8, driftage gearwheel 13, brake disc 10, driftage upper bearing (metal) 14 and driftage lower bearing 9 form, driftage small gear 12 transmits from nacelle chassis 11, with driftage gearwheel 13 engagements that are fastened on cabin seat cylinder 7.Junction point is provided with sealing strip between the cabin front shroud 3 in left sideboard 22, right sideboard 18 and cabin 24 and the cabin back cover 20.Driftage upper bearing (metal) 14 and driftage lower bearing 9 are the ordinary construction radial-thrust bearing of the low precision of low speed.
But be somebody's turn to do the wind generating set engine room of on-site maintenance operation, that the cabin is in deployed condition shown in the accompanying drawing, 19 elongations of two oil cylinders, four pull bar 4 elongations, left sideboard 22 and right sideboard 18 rotate 90 degree around hinge axis 23 and fell, left sideboard 22 and right sideboard 18 become the floor, the personnel that can walk, the finding that can leave with instrument and remove, area of operation has increased twice, half has become safety screen after putting down top board, and pull bar 4 puts down becomes safe fence.Large parts such as gear-box and generating etc., can use hoist 2 to sling and turn over the angle of being convenient to keep in repair, the origin-location is put down and is keeped in repair dismounting and change part, do not hang nacelle chassis 11, the swing arm of hoist 2 can be put beyond the cabin front shroud 3, can be with parts, instrument and large part 24 up and down handlings to ground from the cabin, the crane gear that the maintaining equipments in the cabin 24 can be other.
After the installation, maintenance in cabin 24 or maintenance operation are finished, the column of hoist 2 is reduced in the cabin 24, two oil cylinders 19 are retracted in the cabin 24, left sideboard 22 and right sideboard 18 pull-ups, fastener hole 21 in a row in the middle of the top board is relative, put on the whole cabin of the fastening rear one-tenth of bolt nut, for the sealing in cabin, but mmi machine cabin front shroud 3 and after engine room cover 20 are provided with sealing strip with the side plate junction point.In order to support hoist 2 work to produce huge tilting moment, adopt the design of cabin seat assembly 6, so that rotating around the tower bar, cabin 24 realizes driftage.Brake disc 10 plays damping function when playing yawing rotation, reaches moving equilibrium, plays braking action when yawing rotation stops.Driftage upper bearing (metal) 14 has enough distances apart with driftage lower bearing 9, bring up enough support moment, and this two bearings is the ordinary construction radial-thrust bearing of the low precision of low speed, its expense is more much lower than driftage special bearing expense, its bearing capacity is also very high, and the section modulus of cabin seat cylinder 7 is very large, and the intensity of system is enough and rigidity is very large, also guarantee the normal engagement of driftage small gear 12 and driftage gearwheel 13, unlikely stress is concentrated affects operating life.
