Abstract
The utility model relates to a blade shear web sling, which is characterized by comprising a front sling and a back sling. Each sling comprises two cantilevers. The bottom ends of the two cantilevers are respectively and movably connected with a lifting hook through a bolt. The top ends of the two cantilevers are connected into one body through a beam. The two ends of the top part of the beam are respectively provided with a lifting point. Because the utility model adopts the front sling and the back sling and the lengths of the two cantilevers of each sling are not equal, the sling is kept horizontal in the lifting process and then the lifting posture of a shear web is consistent with the splicing posture in a blade. Therefore, in the die assembly process, the shear web and a shell of the blade can be coated with die assembly glue at the same time and one-step die assembly is realized. The utility model can be extensively applied to the manufacture of a wind driven generator blade.
Description
Technical field
The utility model relates to a kind of blade installation suspender, particularly about a kind of blade shear web suspender that is used for large-scale wind generating blade production technology.
Background technology
Blade is the core component of aerogenerator, and cost accounts for 1/4 to 1/3 of entire equipment.The existing blade that adopts is pre-curved blade, and this blade is outwardly-bent at tip segment, makes blade under rotary state, even can also keep certain distance with tower body when being in high wind, and then avoids blade bump pylon.Pre-curved blade permits that because of it crooked quantitative change is big, and rigidity is suitable, thereby can reduce material usage, makes weight saving, and then obtains more wind energy.The pre-curved blade of wind-power electricity generation is made up of upper shell, lower house and shear web three parts, and wherein shear web is the critical component of shearing resistance in the wind power generation blade structure, in the manufacturing process of blade, shear web be need before the blade matched moulds, carry out bonding.But at present shear web is to carry out bondingly at twice, promptly makes its lower surface and blade upper and lower casing respectively after the bonding curing earlier, carries out whole matched moulds again and operates.Making has so simultaneously also increased the time that takies mould by complex operation, can't realize that the bonding and matched moulds of shear web carries out simultaneously.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of blade shear web suspender that can realize the disposable matched moulds of blade, practicality simple to operate.
For achieving the above object, the utility model is taked following technical scheme: a kind of blade shear web suspender, it is characterized in that: it comprises former and later two suspenders, each described suspender includes two cantilevers, the bottom of described two cantilevers flexibly connects a suspension hook by bolt respectively, the top of described two cantilevers links into an integrated entity by a crossbeam, and is respectively arranged with a suspension centre at the two ends, top of described crossbeam.
The crossbeam length of suspender is less than the crossbeam length of described back suspender before described.
Each described suspension centre on described former and later two suspenders is and is symmetrical arranged.
The length of described two cantilevers is determined according to the elevation and the size of shear web.
The length of a wherein described cantilever of each described suspender is greater than the length of another described cantilever.
Each described suspension hook is respectively so that corresponding described cantilever is that 90 ° of rotations are carried out in the axle center with it.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to adopt former and later two suspenders, and being uneven in length of two cantilevers of each suspender, when lifting, can make suspender maintenance level, and then can guarantee that the lifting attitude of shear web is consistent with bonding attitude in blade, therefore when matched moulds, can on shear web and blade shell, smear matched moulds glue simultaneously, realize one time matched moulds.2, the utility model since the crossbeam length of the preceding suspender that adopts less than the crossbeam length of back suspender, and the suspension centre on each crossbeam is and is symmetrical arranged, in use, the crossbeam of preceding suspender is placed on the root of shear web, the crossbeam of back suspender is placed on the tip of shear web, its practicality simple to operate neither destroys the integral structure of shear web, has saved the Production Time of blade again.The utility model can be widely used in the blade of wind-driven generator making.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present utility model.
The specific embodiment
Because shear web is made up of two parts, link to each other by pipe link between two parts, slit about 100mm is arranged between upper and lower bonding plane, and the utility model utilizes the structure of shear web to design, and below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises former and later two suspenders 1, each suspender 1 includes two cantilevers 2,3, the length of two cantilevers 2,3 is determined according to the elevation and the size of shear web, and the length of cantilever 2 is greater than the length of cantilever 3, because being uneven in length of two cantilevers 2,3 can make suspender 1 maintenance level when lifting, and then can guarantee that the lifting attitude of shear web is consistent with bonding attitude in blade.The bottom of two cantilevers 2,3 flexibly connects a suspension hook 4 by bolt respectively, and each suspension hook 4 can be that 90 ° of rotations are carried out in the axle center with cantilever corresponding with it respectively.The top of two cantilevers 2,3 links into an integrated entity by a crossbeam 5, and is respectively arranged with a suspension centre 6 at the two ends, top of crossbeam 5.
In the foregoing description, the crossbeam 5 of two suspenders 1 is uneven in length, and crossbeam 5 length of preceding suspender 1 are less than crossbeam 5 length of back suspender 1, and each suspension centre 6 of former and later two suspenders 1 is and is symmetrical arranged.
When lifting, two suspenders use simultaneously, and crossbeam 3 length of preceding suspender are short, and crossbeam 3 length of back suspender are long, and suspension centre 4 is symmetrically distributed.
The utility model in use, former and later two suspenders 1 use simultaneously, the crossbeam 5 of preceding suspender 1 is placed on the root of shear web, the crossbeam 5 of back suspender 1 is placed on the tip of shear web, between two suspenders 1 at a distance of 10m.Earlier each suspension hook 4 and suspender 1 are kept horizontal positioned, make its gap of putting into shear web, with each suspension hook 4 half-twist, each suspension hook 4 is connected with each cantilever by bolt then again.After suspender 1 and shear web connected, the workman can carry out the gluing work of blade shell and shear web.During 1 lifting of two suspenders, keep the level height unanimity, just can guarantee that the attitude of shear web is consistent with the attitude of blade shell, can when matched moulds, can on shear web and blade shell, smear matched moulds glue simultaneously thus, realize one time matched moulds.
The various embodiments described above only are used to illustrate the utility model; wherein the structure of each parts, connection mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement all should not got rid of outside protection domain of the present utility model.
