The specific embodiment
Embodiment one
Shown in Fig. 2-4; The utility model provides a kind of hanging device; This hanging device comprises a hoisting crane 1; The homonymy of hoisting crane base 11 overhang be provided with between two foundation beams, 12, two bottom girders 12 be used for ccontaining by the space of lifting object, bottom girder 12 be provided be used to connect bottom girder 12 with by the connecting device of lifting object be used to hold tightly enclasp device by lifting object.
As the specific embodiment of present embodiment, wherein connecting device is the lifting rope 3 more than two; Lifting rope 3 one ends are separately fixed on two bottom girders 12, and lifting rope 3 other ends are equipped with and are used to hang on by the hook on the lifting object 31; If select the lifting rope 3 more than three for use, then lifting rope 3 does not steadily go up and down along conplane vertical direction with assurance hoisting crane 1 on same straight line with bottom girder 12 these fixing ends; Preferably, lifting rope 3 is four, and symmetry is located on two bottom girders 12, and is as shown in Figure 3.Enclasp device is plural expansion link 4; Expansion link 4 one ends are separately fixed on two bottom girders 12; Expansion link 4 other ends are equipped with and are used to hold the clamp 41 by lifting object, and clamp 41 is hinged with expansion link 4, are convenient to cooperating to regulate and hold angle according to the catch surface of clamp 41 and first segment tower tube 10 outer walls.Preferably, expansion link 4 is four, and symmetry is located between two bottom girders 12, and is as shown in Figure 3.Expansion link 4 can adopt hydraulic ram, and the cylinder body of hydraulic ram is fixed on the bottom girder 12, the hinged clamp 41 of the piston end of hydraulic ram, and the catch surface of clamp 41 cooperates with the first tower tube, 10 outer walls.As the preferred implementation of the foregoing description, as shown in Figure 3, the end relative fixed of expansion link 4 is on the medial surface of bottom girder 12, so that clamp 41 is more stable when clamping the tower tube.
The hanging device of the utility model realizes climbing function through existing common hoisting crane is structurally improved, and detailed process is shown in Fig. 5-10; At first the hoisting crane base is placed on the marine basis; The suspension hook of hoisting crane is hung on first segment tower tube top, and starter motor shrinks and suspension hook bonded assembly steel rope 13 is lifted on first segment tower tube 10 in the gap between two bottom girders 12; And first segment tower tube 10 bottoms are captiveed joint with marine basic 02; Then the hook 31 of fixing four lifting rope 3 ends on the bottom girder 12 is hung on the link of first segment tower tube 10 top perimeter (this moment, suspension hook still was hung on first segment tower tube top), at this starter motor and shrink steel rope 13 and make hoisting crane rise to the first tower tube, 10 tops, make the clamp 41 of its piston end be held in the outer wall of the first tower tube 10 through driving the hydraulic ram elongation then; Four clamps 41 are tightly held the first tower tube 10 tightly makes hoisting crane 1 overall fixed on the first tower tube 10; At the lifting second tower tube 20, circulate successively then, so to the last a joint tower tube installs; As required; The lifting function last joint tower tube tip position that climbs is installed cabin 03 and impeller 04 more successively, through elongation and suspension hook bonded assembly steel rope 13 hoisting crane is dropped on marine basic 02 plane more at last.Solved the not enough technical matters of common hoisting crane hoisting height, prior art uses large-scale marine hanging device installation offshore wind farm unit to reduce cost of installation relatively, has simplified erection procedure, has improved installation effectiveness.
Like Fig. 2, shown in 3, in order to make hoisting crane steady more safety in the process of climbing, be equipped with clump weight 5 in bottom girder 12 lower ends, clump weight 5 is through the lower surface sliding block joint of slide rail 6 with bottom girder 12.Concentrate on the line of centers of tower tube (shown in Fig. 6-10) in mobile center of gravity of regulating hoisting crane on the slide rail 6 through clump weight 5.Hanging device also comprises the actuating device (not shown) that driving clump weight 5 moves on slide rail 6; Driving clump weight through actuating device moves on slide rail; Convenient, for further promoting the automation mechanized operation of hanging device, proving installation can be set on hoisting crane its center-of-gravity position is detected; Make clump weight move to a suitable position through the computed in software accessory drive, the hoisting crane center of gravity just in time with tower tube central lines.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
