Description

A kind of wind power generation blade C type web handling frock
Technical field
The utility model belongs to frock, is specifically related to a kind of wind power generation blade C type web handling frock.
Background technology
C type web is a kind of parts that use in the wind power plant, and its effect is to support upper shell and lower house.With shown in the accompanying drawing 2, C type web 3 is provided with flange 4 in upper and lower end parts like accompanying drawing 1, and this flange 4 is used to increase the area of contact of C type web 3 and upper shell 1 and lower house 2.C type web 3 is captiveed joint with lower house 2 with upper shell 1 through adhesive agent 5.
In actual engineering, generally adopt hanging device that C type web 3 is sling, smear adhesive agent 5 at flange 4 places of C type web 3 then, then C type web 3 is bonded on upper shell 1 and the lower house 2.The difficult point of said process is after C type web 3 is sling, and makes the vertical state of its whole maintenance.Comprise following four kinds of lifting modes in the prior art: 1. in the production of blade, the low weight C type web 3 of weight can punch on flange and connect handling (like Fig. 3) through iron chains.But along with the development of blade industry, it is increasing that blade dimensions becomes, and C type web 3 is also increasing thereupon.Because the flange 4 of C type web 3 is thin, C type web 3 self is heavier, flange 4 can not bear the weight of C type web 3.So original handling method has not been suitable on the existing C type web 3.2. most common form is exactly with the 3 horizontal handlings (like Fig. 4) of C type web with suspender belt in producing at present.Though this mode is simple, when C type web 3 and blade lower half shell 2 are bonding, bring inconvenience.So this is a kind of traffic program, be not suitable for auxiliary blade production.3. in the method for many solution C type webs 3 handlings, one of which is exactly to stick with paste glass woven fabric at C type web 3 both sides hands to make suspender belt (like Fig. 5).Though this method can satisfy the handling requirement, on blade forming technology, have more one procedure again.This mode is the lost labor not only, and will wait for resin solidification, and the whole operation process consumes 1 hour at least.So this method is not the best.4. utilize frock, on C type web 3 main bodys,, the both sides frock is connected into an integral body (like Fig. 6) through bolt according to the pitch of holes punching of frock.This method can satisfy C type web 3 and lower half shell 2 bonding requirements, but to causing damage on C type web 3 structures, even repair the stress concentration that can not eliminate hole, for the quality of blade hides some dangers for.
In addition, must avoid moving around in C type web 3 and lower half shell 2 bonding process, produce bubbles in the lining cement 5 if move to cause, thereby reduce bind strength; And C type web 3 is not a symmetrical structure under vertical state.So will make the very heavy C type web of quality 3 keep vertical state is a technical barrier of wind electricity blade industry always.
Summary of the invention
The utility model provides a kind of wind power generation blade C type web handling frock to the defective of prior art.
The utility model is achieved in that a kind of wind power generation blade C type web handling frock, comprises plate washer and lower baffle, goes up wherein that plate washer comprises overhead gage plane, overhead gage vertical plane, lifting eye bolt isosceles right angle tooth, lifting eye bolt hole, overhead gage tie bolt hole, equilateral triangle tooth cushion block, eyenut, equilateral triangle teeth, the plate rubber pad performs; Wherein the overhead gage plane is provided with the overhead gage vertical plane is vertical, and forming the cross section is " L " type structure, and lifting eye bolt hole and isosceles right angle tooth are set at the back side on overhead gage plane; In the lifting eye bolt hole, lifting eye bolt are set, the elongated shape in lifting eye bolt hole, direction and C type web thickness direction are in the same way; Lifting eye bolt portion within it slide in order to seek C type web center of gravity; Under the state of slinging, keep vertically thereby make, towards the one side of overhead gage vertical plane equilateral triangle tooth cushion block is set in the lifting eye bolt hole, this equilateral rake tooth cushion block is two guide rails that laterally arrange; Guide rail is along the long length direction setting in lifting eye bolt hole; The convexity of equilateral triangle is set on the equilateral triangle tooth cushion block, and an end of lifting eye bolt is set to helicitic texture, and this helicitic texture is corresponding with the helicitic texture of eyenut; Eyenut be provided with equilateral triangle tooth cushion block on the protruding cooresponding convexity of equilateral triangle; Lifting eye bolt are fixed through equilateral triangle tooth cushion block and eyenut because the teeth in equilateral triangle tooth cushion block and the equilateral triangle tooth are equilateral triangles, both sides stressed form identical; So cooperate down at both; Lifting eye bolt can not slide arbitrarily in long strip type lifting eye bolt hole, are provided with the plate rubber pad that performs in the one side of overhead gage vertical plane towards the overhead gage plane
The cross section of said lower baffle plate also is " L " type, and it also comprises back-up block, puller bolt, welded nut, groove, slide block, track, lower baffle tie bolt hole, lower baffle plate plane, lower baffle plate vertical plane, lower baffle rubber pad, and wherein captive joint with the lower baffle plate vertical plane in the lower baffle plate plane; Forming the cross section is the structure of " L " type, on the lower baffle plate vertical plane, has groove, and track is set in groove; Being provided with in the track can be along the slide block of slide; Welded nut is fixed on the slide block, and welded nut runs through slide block, groove and lower baffle plate vertical plane, and puller bolt is fixed on the welded nut through screw thread; Roof pressure groove inner slide outwards slides according to the route of track; Roof pressure C type web surface also is provided with the lower baffle rubber pad at the back side of lower baffle plate vertical plane, on the lower baffle plate plane, has the tie bolt hole.
Aforesaid a kind of wind power generation blade C type web handling frock wherein, also comprises tie bolt, isosceles right angle tooth cushion block and coupling nut.
Use the effect of the utility model to be: can be suitable for the handling of various model C type webs, and can make C type web after the lifting remain vertical state to be convenient to bondingly, in blade production, to have improved production efficiency, reduced productive costs.
