Description
Technical field
The utility model relates to wind power principal axis accessory appliances field, particularly relates to a kind of special hanger being convenient to the lifting main shaft adjusted.
Background technology
In wind-powered electricity generation industry, general main shaft, when assembling, needs main shaft to be installed on mainframe together with bearing, the level of main-shaft axis will be kept in the process of installing, but because the size of main shaft is larger and weight ratio is heavier, therefore, cause assembling difficulty, and there is potential safety hazard.The method of existing assembling main shaft is generally be banded on main shaft with suspender belt, under the prerequisite keeping main shaft to be horizontal, main shaft is installed on mainframe together with bearing.The shortcoming of this assembly method is, when assembling, due to the obstruction of suspender belt, main shaft can not once just be seated, and is difficult to keep main shaft balancing in the process of assembling.
Although the suspender of more existing lifting main shafts at present, the troublesome poeration when adjusting the balance of suspender, also more time-consuming.
Utility model content
The technical matters that the utility model mainly solves is, provides a kind of and can keep principal axis balance and be easy to just to adjust the special hanger of the lifting main shaft that suspender balances when lifting.
The utility model solves the technical scheme that its technical matters adopts: a kind of special hanger being convenient to the lifting main shaft adjusted, comprise entablatrance, cross sill, vertical beam is provided with between entablatrance, cross sill, vertical beam is provided with unthreaded hole, an adjusting portion be sheathed on entablatrance is provided with above entablatrance, described adjusting portion is provided with a lifting hole(eyelet), the bottom surface of entablatrance is provided with several zig-zags projections, and the inner bottom surface relative with entablatrance bottom surface of adjusting portion is provided with the sawtooth mated with zig-zag projection; Cross sill and vertical beam intersection are provided with the groove of cooperation.
Preferably, the size of the height of adjusting portion inside is greater than the height of entablatrance, like this be arranged so that adjusting portion utilizes deadweight to ride over entablatrance upper surface when not lifting, namely now the sawtooth of adjusting portion does not coordinate with the projection of entablatrance bottom surface, adjusting portion can along its present position of entablatrance slide control, and once the suspender in adjusting portion is pulled up, the sawtooth of adjusting portion inside and the projection of entablatrance closely cooperate, adjusting portion cannot transverse shifting again.
The utility model is simple to operate, and the used time of adjustment suspender balance is few, more convenient.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram being convenient to the special hanger of the lifting main shaft adjusted of the utility model;
Fig. 2 is the lateral plan of adjusting portion in Fig. 1;
Fig. 3 is the view after Fig. 2 lifts by crane.
In figure: 1, entablatrance 2, cross sill 3, vertical beam 4, unthreaded hole 5, adjusting portion 6, lifting hole(eyelet) 7, zig-zag projection 8, cooperation groove 9, bolt 10, main shaft 11, sawtooth.
Detailed description of the invention
Clearly understanding to have technical characteristic of the present utility model, object and effect, now contrasting accompanying drawing and describing detailed description of the invention of the present utility model in detail.
As shown in Figure 1 to Figure 3, a kind of special hanger being convenient to the lifting main shaft adjusted, comprise entablatrance 1, cross sill 2, entablatrance 1, vertical beam 3 is provided with between cross sill 2, vertical beam 3 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 3 is provided with unthreaded hole 4, the flange of different size is connected by bolt 9, entablatrance 1 is provided with an adjusting portion 5 be sheathed on entablatrance 1 above, described adjusting portion 5 is provided with a lifting hole(eyelet) 6, the bottom surface of entablatrance 1 is provided with several zig-zag projections 7, the inner bottom surface relative with entablatrance 1 bottom surface of adjusting portion 5 is provided with the sawtooth 11 mated with zig-zag protruding 7, adjusting portion 5 can be moved according to the main shaft 10 of different size and weight, the balance of whole device during to ensure to lift main shaft 10, cross sill 2 and vertical beam 3 intersection are provided with and coordinate groove 8, coordinate the effect of groove 8 to be prevent cross sill 2 from damaging main shaft 10 with the intersection of vertical beam 3.
Crane plays whole device, move to the front end of main shaft 10, the cross sill 2 of suspender is stretched in the interstitial hole of main shaft 10, when the inner end surface of vertical beam 3 contacts with the flange face of main shaft 10, stop mobile, with bolt 9, main shaft 10 and suspender are secured together, regulate the position of adjusting portion 5, make suspender and frock keep state of equilibrium, crane starts to pull-up, and whole device and main shaft 10 have just been lifted.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
