Abstract
The utility model particularly discloses a variable pitch speed reducer lifting appliance of a large-scaled wind generating set. The variable pitch speed reducer lifting appliance comprises a C-L bracket, wherein a single-hole lifting lug and a multi-hole lifting lug are arranged at the top end of the bracket, and a speed reducer fixing frame and an arc-shaped groove clamping plate are arranged at the bottom end of the bracket. The variable pitch speed reducer lifting appliance is capable of rapidly realizing that a speed reducer is horizontally lifted and is conveniently installed in a hub; and the hoisting time of the speed reducer is saved, the potential safety hazard is eliminated, the labor intensity is reduced, and the problem of difficulty in horizontally lifting and installing of the variable pitch speed reducer is solved.
Description
Technical field
The utility model relates to a kind of Large-scale Wind Turbines variable pitch speed reducer suspender, particularly wind generating set pitch control reductor hoisting appliance.
Background technology
The center of gravity of wind generating set pitch control reductor is positioned at outside mounting flange, lifting difficulty, and be arranged on wheel hub inner chamber depths, becoming the little tooth of oar need to stretch out and be meshed with the pitch variable bearings bull gear from mounting hole.Need when mounted gear case is sent into wheel hub inside, from inside to outside with the internally toothed annulus engagement of pitch variable bearings, could success complete assembling.Original technology adopts " C " type tool lifting appliance, can not satisfy the operating mode operating needs fully, and the suspender dismounting is slow, is difficult to variable propeller gearbox is hung level, needs the manpower adjustment, and efficiency of assembling is low and assembling is difficult.
The utility model content
The shortcoming that exists for solving prior art, the utility model specifically discloses a kind of Large-scale Wind Turbines variable pitch speed reducer suspender.
The technical solution adopted in the utility model is as follows;
A kind of Large-scale Wind Turbines variable pitch speed reducer suspender, it comprises " C-L " type support, is provided with single hole hanger and porous lifting lug on the top of support, is provided with reductor fixed mount and arc groove clamp in the bottom of support.
Described " C-L " type support comprises " C " type frame, and on the top of described " C " type frame with the bottom is equidirectional is vertically welded with two straight-bars, these two straight-bars are respectively upper straight rod and lower straight-bar.
Described " C-L " type support is web structure.
Described porous lifting lug is welded on upper straight rod.
Described reductor fixed mount is connected with lower straight-bar by the 3rd hanger.
Described arc groove clamp is movably connected on lower straight-bar.
Described reductor fixed mount comprises two semi arch steel plates, and top and the bottom of described two semi arch steel plates are flexibly connected by bolt.
Described single hole hanger is located at " C " upper end of type frame.
The center of gravity of described suspender and reductor integral body is on the lifting line of centers, and described porous lifting lug is also on the lifting line of centers.
Installation method of the present utility model comprises the steps:
1, crane is connected with porous lifting lug, the single hole hanger of " C-L " type support by suspender belt, and the suspender own level is sling, and opens and tightens tie bolt after the reductor fixed mount installs reductor;
2, take off the suspender belt that porous lifting lug connects, the hoisting process suspender belt only is connected with the single hole hanger, regulates the position of arc groove clamp, realizes the lifting of reductor level, after reductor is hung in hole for hoist, then moves to rigging position, completes the fitting work of reductor.
The beneficial effects of the utility model are as follows:
1, " C-L " type support is web structure, and the porous lifting lug of reductor utilizes top passageway, and the installation site is on " C-L " type support, and the installation site departs from into the center of the hole for hoist of reductor on wheel hub, satisfies the operating mode operating needs fully.Another suspender increases separately a single hole hanger, realizes the level lifting of suspender self.
2, the forward end of reductor center-of-gravity position, be positioned at outside mounting flange, utilize the suspender deadweight to carry out counterweight, suspension centre is transferred to suitable position, the arc groove clamp can move on " C-L " type support level direction flexibly, prevent from toppling in its hoisting process, coordinate simultaneously porous lifting lug to realize the quick horizontal Hoisting Program of reductor, it is convenient to lift.
3, the reductor fixed mount is connected with reductor by 2 two semi arch steel plates are with bolts, and dismounting is convenient.
Description of drawings
Fig. 1 is that the utility model implements to use view;
Fig. 2 is that the utility model is implemented schematic diagram;
Fig. 3 is the constructional drawing of " C-L " type support;
In figure 1, porous lifting lug, 2, the single hole hanger, 3, " C-L " type support, 4, the arc groove clamp, 5, variable pitch speed reducer, 6, reductor fixed mount, 7. " C " type frame, 8 upper straight rods, 9 times straight-bars, 10 suspender center-of-gravitys position, 11 lifting line of centerss, 12 reductor center-of-gravitys position, 13 the 3rd hangers.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As Fig. 1 ~ shown in Figure 3, the utility model comprises " C-L " type support 3, top at " C-L " type support 3 is provided with single hole hanger 2 and porous lifting lug 1, bottom at " C-L " type support 3 is provided with reductor fixed mount 6 and arc groove clamp 4, provided suspender center-of-gravity position 10, lifting line of centers 11, reductor center-of-gravity position 12 in Fig. 1, these three center-of-gravitys position are not point-blank.
" C-L " type support 3 comprises " C " type frame 7, and on the top of " C " type frame 7 with the bottom is equidirectional is vertically welded with two straight-bars, these two straight-bars are respectively upper straight rod 8 and lower straight-bar 9.Porous lifting lug 1 is welded on upper straight rod 8.Reductor fixed mount 6 is connected with lower straight-bar 9 by the 3rd hanger 13.Arc groove clamp 4 is movably connected on lower straight-bar 9.Reductor fixed mount 6 comprises two semi arch steel plates, and top and the bottom of two semi arch steel plates are flexibly connected by bolt.
