Abstract
The utility model discloses a damage-free demoulding sucking disc for a large-sized wind power generation blade. The demoulding sucking disc comprises a disk, a pit is formed in the lower surface of the disk; a through hole is formed in the upper surface of the disk; the through hole is communicated with the pit; an extraction opening is formed above the through hole; a lifting lug is arranged on the upper surface of the disk. The damage-free demoulding sucking disc disclosed by the utility model has the advantages as follows: the damage to the blade by adopting the conventional mode is avoided, the degree of automation of demoulding is improved, and manpower is saved.
Description
Technical field
The utility model relates to the stripper apparatus of the blade of wind-powered electricity generation, is specifically related to the harmless demoulding sucker of a kind of large-scale wind generating blade.
Background technology
China is since reform and opening-up, and national economy develops rapidly, and power consumption sharply increases.There is huge environmental issue and carbon emission problem in traditional fossil fuel generating.For this reason, development clean energy resource becomes the task of top priority, and wind-powered electricity generation is exactly one of them.
Along with the raising of wind-driven generator single-machine capacity, the size of supporting fiberglass blade and weight is also in continuous increase with it, along with the increase of length of blade, and the increase of amount of deflection, existing blade ejection technique has been difficult to adapt to the demoulding of large-scale blade.
Traditional blade ejection technique adopts the mode of suspender belt lifting, and this mode is lifted by crane, and the trailing edge of blade lifting position is stressed very large, and misoperation is easy to cause the cracking of trailing edge, causes the damage of blade.
Utility model content
The technical problems to be solved in the utility model is: traditional blade ejection technique adopts the mode of suspender belt lifting, this mode is lifted by crane, the trailing edge of blade lifting position is stressed very large, misoperation is easy to cause the cracking of trailing edge, cause the damage of blade, thereby provide a kind of large-scale wind generating blade to can't harm demoulding sucker.
For achieving the above object, the technical solution of the utility model is as follows:
The harmless demoulding sucker of a kind of large-scale wind generating blade, described demoulding sucker comprises a disk, described lower disk surface is provided with pit, described disk upper surface is provided with through hole, described through hole is communicated with pit, and described through hole is provided with bleeding point, and described disk upper surface is also provided with hanger.
In a preferred embodiment of the present utility model, outside the edge of described pit, be arranged with some circular grooves, described circular groove has been embedded with rubber ring.
In a preferred embodiment of the present utility model, described bleeding point and through hole are threaded connection, and are wound around raw material band between screw thread.
By technique scheme, the beneficial effects of the utility model are:
The utility model has been avoided the damage of traditional stripping means to blade, and has improved the automation of the demoulding, has saved manpower.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is cutaway view of the present utility model;
Fig. 2 is side view of the present utility model;
Fig. 3 is top view of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the harmless demoulding sucker of a kind of large-scale wind generating blade that the utility model provides, mainly comprises disk 100 main elements.
Be provided with pit 110 at the lower surface of disk 100.
In the time that the lower surface of disk 100 contacts with the blade that needs the demoulding, between the pit 110 of disk 100 lower surfaces and blade, can there is certain space, in the time that disk 100 connects vacuum equipment, utilize disk 100 and lifted by crane the space between blade, produce negative pressure, thereby blade is closely connected with disk 100, blade is fastened on disk 100, can not come off.
Outside the edge of pit 110, be arranged with several circular grooves 120(referring to Fig. 3), in the utility model, two grooves 120 specifically can be set, in groove 120, be provided with rubber ring 121.
The rubber ring 121 that the utility model adopts is acrylonitrile-butadiene rubber ring, because acrylonitrile-butadiene rubber ring has good elasticity, flexible resistance and the adaptability to environment for use, make the disk 100 that the utility model provides be applicable to various blades.
Be provided with through hole 130 at the upper surface of disk 100.
Referring to Fig. 1 and Fig. 3, through hole 130, is communicated with pit 110, is provided with bleeding point 131 on through hole, and it is to be convenient to bleeding point 131 to extract the gas between disk 100 lower surfaces and blade.
Referring to Fig. 1, bleeding point 131, itself and through hole 130 are threaded connection, and it is to be connected with vacuum equipment, and vacuum equipment can extract the gas between disk 100 lower surfaces and blade by it.
Bad in order to prevent the sealing effectiveness between bleeding point 131 and through hole 130, make negative pressure too little, absorption affinity does not reach designing requirement, the normally demoulding of blade, between the screw thread of bleeding point 131 and through hole 130, be wound around raw material band, thereby guaranteed the sealing effectiveness between bleeding point 131 and through hole 130.
Upper surface at disk 100 is also provided with hanger 140.
Referring to Fig. 2, hanger 140, entirety is triangle, and it is welded on the middle part of disk 100, offers a connecting hole 141 in the middle part of hanger 140, the utility model can be connected with connecting hole 141 by the hook on suspender, thereby sucker is ticked together with blade, thereby realized the demoulding, like this, greatly improve the automation of the demoulding, saved manpower.
Concrete use step of the present utility model is as follows:
First the lower surface of disk 100 is contacted with the blade that needs the demoulding, then vacuum equipment is connected with bleeding point 131, vacuum equipment is extracted the air between disk 100 and blade out, at this moment blade can be fastened on the lower surface of disk 100, then the hook of suspender is connected with the connecting hole 141 of hanger 140, sucker is ticked together with blade, thereby realized the demoulding.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
