Abstract
The utility model provides a wind turbine blade root holding device, which comprises a circular tube portion and a semi-U-shaped tank portion, wherein each end of the semi-U-shaped tank portion is provided with a rectangular cross section. The wind turbine blade root holding device is characterized in that the circular tube portion welded on a first leg of the semi-U-shaped tank portion is basically parallel to a second leg of the semi-U-shaped tank portion. The wind turbine blade root holding device can prevent heavy root of a blade dropping when overturning a blade die, and is light in weight and easy in operation.
Description
Technical field
The utility model relates to a kind of holding device, especially the holding device of turbine blade root.
Background technology
The trouble that the wind turbine blade producer often runs into is: when the upset blade mold, how to prevent that the heavy root of blade from falling.Used nipper to prevent the above-mentioned too early demoulding, but they all can not satisfy following requirement, promptly in light weight, quick detachable when not required, can provide enough intensity that root is remained in the mould again simultaneously.
The utility model content
The utility model provides a kind of turbine blade root holding device, and it has solved above-mentioned problem.
This turbine blade root holding device comprises pipe portion and half U-shaped case portion, and each end of half U-shaped case portion has rectangular cross section, it is characterized in that, pipe portion is welded on first leg of half U-shaped case portion, and parallel with second leg of half U-shaped case portion basically.
According to an embodiment, this pipe portion is set to rigidity and is installed on the pipe or bar of blade mold.
According to an embodiment, utilize the screw that has knob, the clamping plate that will contact with root of blade are fixed on described second leg.
According to a preferred embodiment, these clamping plate are universal pivot clamping plate.
Adopt this holding device, the blade producer can prevent that the heavy root of blade from falling when the upset blade mold.And this holding device is in light weight, easily carrying.
Another purpose of the present utility model is that this pipe portion can freely be pivoted, so that the correct placement of this holding device.Another purpose is to make this holding device that the storage location of one can be arranged on mould.
Description of drawings
Below, describe the utility model in detail with reference to accompanying drawing and by non-limiting example, in the accompanying drawing:
Fig. 1 is a stereogram, only illustrate one mounted according to wind turbine blade holding device of the present utility model;
Fig. 2 is a front view, shows according to wind turbine blade holding device of the present utility model;
Fig. 3 is a side view, and the holding device of Fig. 2 is shown;
Fig. 4 is the front view similar to Fig. 2, shows the part of holding device and mould and root of blade;
Fig. 5 is the exploded perspective view of this holding device.
In the accompanying drawing, identical parts are represented with identical Reference numeral.
The specific embodiment
As shown in Figure 1, be used for keeping turbine blade root 1 according to turbine blade root holding device 3 of the present utility model (being designated hereinafter simply as holding device) in the butt part 2 of blade mold.Mold frame is made by rectangular steel pipe 5.
Referring to Fig. 2,4 and 5, holding device 3 is made of pipe portion 6 and half U-shaped case portion 7.Each end of half U-shaped case portion 7 all has rectangular cross section.Pipe portion 6 is made by the aluminum pipe of the about 60-120mm of diameter, the about 1.5-8mm of wall thickness, and these sizes depend on the size and the type of the blade of producing certainly.Half U-shaped case portion 7 makes by aluminium sheet is welded together, the about 2-5mm of aluminium plate thickness, and this also depends on the size and the type of the blade of producing.Pipe portion 6 is welded on first leg of half U-shaped case portion 7, and parallel with second leg of half U-shaped case portion 7 basically.As described below, pipe portion 6 will be connected on the steel pipe 5 of mold frame.
Referring to Fig. 5, removable erection column 12 can be assembled in the end of pipe portion 6.The exposed junction of erection column 12 can have pin thread, so that can mesh with the negative thread in the pipe 11.Pipe 11 is installed on the end of steel pipe 5 of mold frame rigidly.Alternatively, pipe 11 can substitute with bar.Pipe portion 6 can directly be enclosed within on pipe 11 or the bar.In both cases, erection column 12 also can omit.This layout of pipe 11 or bar and erection column 12 makes holding device can be easy to dismounting, and pipe portion can freely be pivoted, thereby helps the correct placement of holding device.
The clamping of root of blade 1 will be described now.Be provided with through hole on second leg parallel with pipe portion 6 of half U-shaped case portion 7, the screw 8 with knob can pass this through hole.By means of the nail body of screw 8, the clamping plate 9 that will contact with root of blade 1 are fixed on described second leg.By the knob of rotary screw 8, can clamping plate 9 are fastening.The place, bottom surface of clamping plate 9 can be provided with the one seat, and this one seat is used to admit hemispherical member 14.Also can be provided with a C clamp 13, cooperate with hemispherical member 14 being used for.In this case, can be provided with a boss at the opening part of described through hole, to cooperate with C clamp 13.Like this, these clamping plate 9 just can universal pivot.
On the one hand, by this way, realized freely pivoting of pipe portion 6; On the other hand, by unclamping screw 8 and this holding device being forwarded to desired location, just can make this holding device that the storage location of one is arranged on mould.
By finite element analysis, the confining force that whole holding device provided is 200-600kg, and this depends on the size and the type of the blade of producing.The gross mass of this holding device is less than 20kg, thereby promotes easily and carry.In addition, as shown in Figure 1, as required, can use a plurality of holding devices 3 at 4 places, a plurality of position.
It will be understood by those skilled in the art that in spirit and scope of the present utility model and can carry out various modifications and improvement.
