Plenty of time, the production cycle of wind electricity blade is increased, the defects of the product problem that cooling meat is brought, there is provided a kind of wind-powered electricity generation leaf
The release method of piece butt prefabricated component.
The present invention is that solve above-mentioned technical problem by following technical proposals：
A kind of release method of wind-power blade root end prefabricated component, its feature be, the wind-power blade root end prefabricated component bag
The exterior region being sequentially connected, connecting portion and hinder marginal part are included, the release method includes following steps：
S1, the both ends of fixed component are connected to the exterior region and the hinder marginal part, and by the fixed component
Bottom be connected to the connecting portion；
S2, the fixed component is lifted by crane so that the wind-power blade root end prefabricated component to be sling from mould.
It is preferred that in the step S1, connection is opened up to the exterior region, the hinder marginal part and the connecting portion
Hole, and be attached the connecting hole and the fixed component by fastener.
It is preferred that the axis of each connecting hole is located at the connection in the wind-power blade root end prefabricated component
Section at hole.
It is preferred that the fastener is screw, the nominal diameter of the screw is more than the internal diameter of the connecting hole.
It is preferred that the hole depth of the connecting hole is 60~65mm.
It is preferred that also include following steps before the step S1：
S11, two position lines are drawn on the wind-power blade root end prefabricated component with laser, between two position lines
It is parallel, and the connecting hole is not in the position line.
It is preferred that in step s 2, the exterior region and the hinder marginal part are first subjected to the lifting demoulding, then again by described in
Wind-power blade root end prefabricated component carries out the integral lifting demoulding.
It is preferred that in step s 2, the fixed component is lifted by crane with driving is started.
It on the basis of common sense in the field is met, above-mentioned each optimum condition, can be combined, it is each preferably real to produce the present invention
Example.
The positive effect of the present invention is：
The release method of the wind-power blade root end prefabricated component of the present invention, it is pre- effectively to wind-power blade root end by fixed component
Product is fixed, and solves the product problem that cure shrinkage is brought.Meanwhile the demoulding for accelerating wind electricity blade prefabricated component was lifted by crane
Journey, the manual labor of operating personnel is reduced, shorten the production cycle of wind electricity blade, reduce the production cost of wind electricity blade.
Brief description of the drawings
Fig. 1 is the flow chart of the release method of the wind-power blade root end prefabricated component of the embodiment of the present invention.
Embodiment
Below by embodiment mode and become apparent from intactly illustrating the present invention with reference to accompanying drawing, but therefore not incite somebody to action this
Invention is limited among described scope of embodiments.
It is irrigated on mould so that wind-power blade root end prefabricated component is made, the wind-power blade root end prefabricated component is included successively
Exterior region, connecting portion and the hinder marginal part of connection.As shown in figure 1, the release method bag of the wind-power blade root end prefabricated component of the present invention
Following steps are included：
S1, the both ends of fixed component are connected to exterior region and hinder marginal part, and the bottom of fixed component is connected to
Connecting portion.
In step S1, it is fastenedly connected between fixed component and wind-power blade root end prefabricated component, has by fixed component
Wind-power blade root end prefabricated component is fixed effect, and wind-power blade root end prefabricated component can solidify and cool down after the demoulding,
So that cooling meat amplitude is very small, the product problem that cure shrinkage is brought is efficiently solved.Preferably, wind-power blade root end is pre-
The temperature of product is preferably lower than after 60 DEG C, and fixed component is arranged on wind-power blade root end prefabricated component with driving, and fixed
Part will be put down gently, slowly when being placed on wind-power blade root end prefabricated component, in order to avoid electric blade root prefabricated component is caused during the demoulding
Damage.
Operating personnel can open up connecting hole to exterior region, hinder marginal part and connecting portion, and by fastener by connecting hole
It is attached with fixed component.Connection between fixed component and wind-power blade root end prefabricated component is easy to by connecting hole.
The axis of each connecting hole is located at the section of the connection hole in wind-power blade root end prefabricated component.The company of opening up
Torch turn and drill bushing can be used by connecing hole, and adjustment drill bushing causes drill bushing hole perpendicular to the surface of wind-power blade root end prefabricated component, then
Capable punching is rotated into using torch, the hole depth of connecting hole can be 60~65mm, then extract torch and turn.Preferably, fastener can
Think screw, and the nominal diameter of screw is more than the internal diameter of connecting hole, so as to effectively strengthen the fastening between screw and connecting hole
Bonding strength.
The demoulding of wind-power blade root end prefabricated component needs to be irrigated together with blade body after completing.In order that obtain wind-powered electricity generation
The effect that blade root prefabricated component can be positioned quick and precisely in subsequent handling, it can use and swash before step S1 is carried out
Light draws two position lines on wind-power blade root end prefabricated component, parallel between two position lines, can by two position lines
Wind-power blade root end prefabricated component Fast Installation is positioned.Wherein, connecting hole is not in position line.
S2, fixed component is lifted by crane so that wind-power blade root end prefabricated component to be sling from mould.
In step S2, fixed component can be lifted by crane with driving is started, it is prefabricated effectively to accelerate wind electricity blade
The demoulding lifting process of part, reduces the manual labor of operating personnel, shortens the production cycle of wind electricity blade, reduce wind electricity blade
Production cost.
After fixed component installs, with the driving lifting demoulding, to be drink spiked, slowly in the demoulding.If overall demoulding when ratio
It is more difficult, exterior region and hinder marginal part first can be subjected to the lifting demoulding, wind-power blade root end prefabricated component is then subjected to entirety again
The lifting demoulding.
Although the embodiment of the present invention is the foregoing described, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
On the premise of the principle and essence of the present invention, various changes or modifications can be made to these embodiments, but these changes and
Modification each falls within protection scope of the present invention.
