Abstract
The utility model provides a special lifting tool for lifting a spindle, and the special lifting tool comprises an upper cross beam and a lower cross beam, wherein a vertical beam is arranged between the upper cross beam and the lower cross beam; a light hole is formed in the vertical beam; multiple lifting points are arranged on the upper surface of the upper cross beam; a hole is formed at the junction between the upper cross beam and the vertical beam. The special lifting tool provided by the utility model is simple to operate and convenient to use, and can be used for reducing the lifting time and greatly improving the working efficiency and safety.
Description
Technical field
The utility model belongs to technical field of wind power generating equipment, relates in particular to a kind of special hanger that lifts main shaft.
Background technology
In the wind-powered electricity generation industry, general main shaft, when being assembled, need to be installed to main shaft on mainframe together with bearing, the level that will keep main-shaft axis in the process of installing, but because the size of main shaft is larger and weight ratio is heavier, therefore, cause the assembling difficulty, and have potential safety hazard.The method of existing assembling main shaft is generally to be banded on main shaft with suspender belt, under the prerequisite that keeps main shaft to be horizontal, main shaft is installed on mainframe together with bearing.The shortcoming of this assembly method is that, in assembling, due to the obstruction of suspender belt, main shaft can not once just be seated.
Summary of the invention
The utility model provides a kind of special hanger that lifts main shaft in order to address the above problem.
The technical solution of the utility model is achieved in that a kind of special hanger that lifts main shaft, comprises entablatrance, cross sill, between entablatrance, cross sill, is provided with vertical beam, and vertical beam is provided with unthreaded hole, is provided with a plurality of suspension centres above entablatrance;
Entablatrance and vertical beam intersection are provided with hole.
The beneficial effects of the utility model are: the utility model is simple to operate, easy to use, has reduced the lifting time, can greatly increase work efficiency and safety.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Part explanation: 1, suspension centre, 2, entablatrance, 3, bolt, 4, vertical beam, 5, cross sill, 6, main shaft, 7, hole, 8, unthreaded hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: a kind of special hanger that lifts main shaft, comprise entablatrance 2, cross sill 5, entablatrance 2, be provided with vertical beam 4 between cross sill 5, vertical beam 4 is welded on the high order end of two crossbeams, form a shape of " n " word of 90 ° of being tilted to the left, vertical beam 4 is provided with unthreaded hole 8, the flange that connects different sizes by bolt 3, be provided with 7 suspension centres 1 above entablatrance 2, can select different suspension centre holes according to the main shaft 6 of different size and weight, the balance of whole device during with assurance lifting main shaft 6, cross sill 5 and vertical beam 4 intersections are provided with hole 7, the effect in hole 7 is to prevent the intersection of cross sill and vertical beam damage main shaft 6.
The crane whole device that plays, move to the front end of main shaft, the cross sill 5 of suspender is stretched in the interstitial hole of main shaft 6, when the inner end surface of vertical beam 4 contacts with the flange face of main shaft 6, stop moving, with bolt 3, main shaft 6 and suspender are secured together, regulate the position of top hole for hoist, make suspender and frock keep state of equilibrium, crane starts upwards to draw, and whole device and main shaft just have been lifted.
