Description
Technical field
The invention belongs to megawatt level wind power generation blade stone tongs technical field, relate generally to and a kind ofly assembled the shear web holding device for handling wind power generation blade inside.
Background technology
Shear web is a kind of for improving the inner structure of wind power generation blade shearing strength value, and it is generally two shear web moulding in advance and is mounted on wind power generation blade inside with the customised design requirement again.
In the prior art, for the handling of wind power generation blade inside shear web several modes that mainly contain are installed: 1, adopt stone tongs that the single handling one by one of shear web is installed; 2, adopt stone tongs that the handling simultaneously of two shear webs is installed; 3, simply adopt the stone tongs handling to install again after the assembling in advance two shear webs.Contrast three kinds of handling mounting meanss of above-mentioned shear web, we find in the practice, when single shear web handling is installed, because shear web is easy to deform at length direction, causes two shear web installing space deviations bigger, installation steps are more loaded down with trivial details, and the installation site needs or else disconnected the adjustment when installing, cause in the adhesive that shear web below applied the more and many places of bubble to fill up again, be difficult for accurately location etc., the shearing strength value of wind power generation blade is descended.By contrast, in order at utmost to reduce the problem in the single shear web handling installation, employing with the simple assembling of two shear webs after again the handling mode of installing be most employing the in the prior art, be used for handling and assembled every technological parameter and the structure that the stone tongs of shear web then needs can guarantee to have assembled shear web.The disclosed shear web stone tongs device of the patent No. 201020542936.4 " MW class wind turbine shear web stone tongs device ", from its technical scheme, though solved two shear webs of handling simultaneously, also simplified after shear web is assembled in advance the problem that handling is again installed, but for two shear webs of not assembling in advance, it also can't satisfy shear web in the length direction particularity of the spacing of position everywhere, especially for the root tip position of shear web, from disclosed technical scheme content, if improve the length direction particularity of the spacing of position everywhere, just need to increase frock quantity, accessory equipments such as driving quantity or use hanging beam, and shear web length direction difference in height is bigger, the employing tool locating is installed, bonding after the installation press down and the dismounting of frock all comparatively loaded down with trivial details, cause subsequent handling longer dead time, even in advance the simple assembling of shear web is avoided distortion on the length direction and the particularity of each location gap, but this grip device is installed, disassembling section is also comparatively loaded down with trivial details, especially for the higher shear web of root.
Summary of the invention
In view of existing problem in the prior art, the objective of the invention is to design between a kind of shear web that can in the handling installation process of shear web, guarantee to have assembled apart from not changing, to shear web structure zero damage, can convenient and swift installing/dismounting, the location handling of placing exactly installs the megawatt level wind power generation blade interior and assembled the shear web holding device, to improve production efficiency and product quality.
In order to realize the foregoing invention purpose, the concrete technical scheme that the present invention takes is: a kind ofly having assembled the shear web holding device for handling wind power generation blade inside, mainly is to be made of Li Liang, left anchor clamps, right anchor clamps, crossbeam, strut bar, spring, upright clamping plate, center shaft; Wherein, the left and right anchor clamps that structure is identical connect and compose " X " shape structure by center shaft; The lower end of a left side anchor clamps, right anchor clamps is symmetrical to be equipped with upright clamping plate; Upright beam, crossbeam have constituted " T " font structure intermediate equilibria hold-down arm, and upright beam and crossbeam link together by axle, and the intermediate equilibria hold-down arm is combined by center shaft and left anchor clamps, right anchor clamps; Left side anchor clamps and right anchor clamps symmetry are located at the both sides of intermediate equilibria hold-down arm, and the two ends of crossbeam are provided with left and right two strut bars, connect and compose the rotation supporting construction by axle and crossbeam; Upright clamping plate on left side anchor clamps, the right anchor clamps are with respect to left strut bar, right strut bar both sides, and the upper end of left anchor clamps, right anchor clamps is respectively equipped with hanger and is used for connecting steel rope; The static structure attitude of shear web holding device is kept by the spring between the anchor clamps of the left and right sides; The intermediate equilibria hold-down arm is provided with aperture, and the steel rope that passes an end bifurcated of aperture on the left strut bar of rotation on the supporting construction, right strut bar and the intermediate equilibria hold-down arm is connected; The surface that contacts with shear web at upright clamping plate, strut bar all is stained with the elasticity leather packing.
Of the present inventionly a kind ofly assembled the shear web holding device for handling wind power generation blade inside, shear web has been assembled in steadily handling, installation, and guarantee its packaging technology size, at utmost reduce the web distortion, enhance productivity and leaf quality, described holding device is simple in structure, and is easy to use, can satisfy operating personal in low level Fast Installation, dismounting frock.
