Description
Technical field
The utility model belongs to the wind power equipment technical field, relates in particular to a kind of special tool of lifting fan wheel hub.
Background technology
Axial fan hub is an important component part in wind power generating set, in Large-scale Wind Turbines, because size, the weight of wheel hub are very large, makes the slinger for wheel hub be made for an insoluble problem.At traditional hanging method, be, on a blade bearing of wheel hub, with bolt, a special leg-of-mutton support is fixed on the inner ring of blade bearing, the correspondence position of 180 ° at bearing, open a square mouthful on the wheel hub shell, a jiao of exposing two other bearing, be connected on outside race with each special plate part of bolt, on three parts, each is porose, with hawser, through these three skies, wheel hub is lifted.Tradition hanging method frock is many, complex structure, and the frock installation process wastes time and energy.
Summary of the invention
The utility model provides a kind of special tool of lifting fan wheel hub, has solved the hanging method complex structure in the background technology, the shortcoming wasted time and energy.
The technical solution of the utility model is achieved in that a kind of special tool of lifting fan wheel hub, comprise main shaft, main shaft is provided with slide block, the slide block below is provided with block, the main shaft of block bottom is provided with spring, main shaft is equipped with three by bolt bottom and hangs pawl, hangs pawl and is connected with pull bar, and pull bar is fixedly connected with slide block;
Described quantity of hanging pawl >=3.
The beneficial effects of the utility model are: the utility model need not increase other frock, directly lifts wheel hub, simple in structure, easy for installation, has reduced the lifting time, has improved work efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is birds-eye view of the present utility model.
Part explanation: 1, main shaft, 2, slide block, 3, pull bar, 4, spring, 5, hang pawl, 6, block.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: a kind of special tool of lifting fan wheel hub, comprise main shaft 1, main shaft 1 is provided with slide block 2, slide block 2 belows are provided with block 6, the main shaft 1 of block 6 bottoms is provided with spring 4, main shaft 1 is equipped with three by bolt bottom and hangs pawl 5, hangs pawl 5 and is connected with pull bar 3, and pull bar 3 is fixedly connected with slide block 2.
The crane whole device that plays, move to wheel hub directly over, slowly descend, under the effect of the power at round mouth edge above gravity and wheel hub and shell, three pawls slowly close up again, when the end of three pawls enter into wheel hub suitable for reading in, three pawls can be separately under the effect of gravity, and at this time crane upwards draws, and three pawls can be attached to the wheel hub inboard tightly, continue upwards to draw, whole device and wheel hub just can be sling.
