Description
Technical field
The invention belongs to megawatt level wind power generation leaf blade hanging clamp art, relate generally to one and assembled shear web holding device for handling wind power generation blade inside.
Background technology
Shear web is a kind of inner structure for improving wind power generation blade shearing strength value, and it is generally, and two shear webs are shaping is in advance mounted on wind power generation blade inside with customised design requirement again.
In the prior art, the handling installation for wind power generation blade inside shear web mainly contains several mode: 1, adopt stone tongs single for shear web handling one by one to be installed; 2, stone tongs is adopted the handling simultaneously of two shear webs to be installed; 3, stone tongs handling is adopted to install again after simply being assembled in advance by two shear webs.Contrast three kinds of handling mounting meanss of above-mentioned shear web, in practice, we find, when single shear web handling is installed, because shear web is easy to deform at length direction, cause two shear web installing space deviations comparatively large, installation steps are more loaded down with trivial details, and installation site needs adjustment of or else breaking when installing, cause bubble in the adhesive applied below shear web more and many places need re-start and fill up, not easily accurate location etc., the shearing strength value of wind power generation blade is declined.By contrast, in order at utmost reduce the problem in single shear web handling installation, adopt the mode that after simply being assembled by two shear webs, handling is installed again to be most in prior art employing, the stone tongs having assembled shear web for handling then needs various process parameters and the structure that can ensure to have assembled shear web.The patent No. 201020542936.4 " MW class wind turbine shear web lifting tong device " disclosed shear web lifting tong device, from its technical scheme, although solve two shear webs of handling simultaneously, also simplify shear web assemble in advance after again handling install problem, but for the shear web that two are not assembled in advance, it also cannot meet the particularity of shear web in the spacing of length direction various loci, especially for the root tip position of shear web, from disclosed technical scheme content, if improve the particularity of the spacing of length direction various loci, just need to increase frock quantity, the accessory equipments such as driving quantity or use hanging beam, and shear web length direction difference in height is larger, employing tool locating is installed, bonding after installation press down and the dismounting of frock all comparatively loaded down with trivial details, cause subsequent handling longer for dead time, even if in advance shear web simply to be assembled the particularity avoiding distortion on length direction and each location gap, but this grip device is installed, disassembling section is also comparatively loaded down with trivial details, especially for the shear web that root is higher.
Summary of the invention
In view of problem existing in prior art, the object of the invention is design and a kind ofly can guarantee that in the handling installation process of shear web the spacing of the shear web assembled can not change, to shear web structure zero damage, the handling of placing exactly of convenient and swift installing/dismounting, location megawatt level wind power generation blade interior can be installed assemble shear web holding device, to improve production efficiency and product quality.
In order to realize foregoing invention object, the concrete technical scheme that the present invention takes is: a kind of handling wind power generation blade inside that is used for has assembled shear web holding device, is mainly made up of vertical beam, left fixture, right fixture, crossbeam, strut bar, spring, vertical clamping plate, center shaft; Wherein, the left and right fixture that structure is identical connects and composes " X " shape structure by center shaft; The lower end of left fixture, right fixture is symmetrical is provided with vertical clamping plate; Vertical beam, crossbeam constitute " T " character form structure intermediate equilibria hold-down arm, and vertical beam and crossbeam are linked together by axle, intermediate equilibria hold-down arm by center shaft together with left fixture, right fixture combination; Left fixture and right fixture 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 rotatable support structure by axle and crossbeam; What the vertical clamping plate on left fixture, right fixture were symmetrical is arranged on rotatable support structure left support bar, right support bar both sides, and the upper end of left fixture, right fixture is respectively equipped with hanger for connecting steel wire ropes; The static structure attitude of shear web holding device is maintained by the spring between the fixture of left and right; Intermediate equilibria hold-down arm is provided with aperture, and the left support bar on rotatable support structure, right support bar are connected with the steel rope of the bifurcated at one end through aperture on intermediate equilibria hold-down arm; The surface contacted with shear web at vertical clamping plate and strut bar is all stained with elasticity leather packing.
One of the present invention is used for handling wind power generation blade inside and has assembled shear web holding device, can steadily handling, install assemble shear web, and ensure its packaging technology size, at utmost reduce web distortion, enhance productivity and leaf quality, described holding device structure is simple, easy to use, can meet operating personal at low level Fast Installation, disassembling fixture.
