The specific embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
The wind-powered electricity generation unit is when Assembly ﹠Disassembly, need the ultra-large type hoisting crane that certain height, amplitude and very big lifting performance are provided, but this performance to main crane arm, height and amplitude have certain requirement, adopt existing independent arm head, then Assembly ﹠Disassembly work is very difficult, the problem that also existence is interfered, windage effect is big.
In order to solve the problem of existing independent arm head, Fig. 3 shows the structural representation of an embodiment of the special-purpose independent arm head of wind-powered electricity generation of the present invention.Be installed in the constructional drawing of the crane jib of wind-powered electricity generation operating mode in conjunction with the special-purpose independent arm head embodiment of wind-powered electricity generation shown in Figure 4, the special-purpose independent arm head of wind-powered electricity generation in the present embodiment comprises: the crane arm head assembly, link span assembly 3 and surpassed arm-tie assembly 2, the crane arm head assembly comprises truss-like arm head 1, conductor rope pulley 8 and assembly pulley 7, conductor rope pulley 8 and assembly pulley 7 are installed in two ends of truss-like arm head 1 respectively, truss-like arm head 1 is connected with link span assembly 3, link span assembly 3 is connected with the minor details arm 4 of main crane arm 5 by connecting portion 9, surpassed 2 of arm-tie assemblies and be installed on the truss-like arm head 1 end that conductor rope pulley 8 is installed, crane arm head assembly and link span assembly 3 on the minor details arm 4 of main crane arm 5 with the integral form Assembly ﹠Disassembly.
In the present embodiment, between crane arm head assembly and the link span assembly with the integral form Assembly ﹠Disassembly, when under the wind-powered electricity generation operating mode, carrying out Assembly ﹠Disassembly so, operating personal has saved the work to the assembly and disassembly between crane arm head assembly and the link span assembly, therefore guaranteed that operating personal can realize fast assembling-disassembling and transportation easily, the operating efficiency of raising operating personal under the wind-powered electricity generation operating mode in use.Surpass the arm-tie assembly and also can carry out Assembly ﹠Disassembly with respect to crane arm head assembly integral body, further improved operating efficiency.
Specifically, the special-purpose independent arm head of wind-powered electricity generation integral transportation in transportation, namely link span assembly and arm head assembly do not need dismounting; Can directly special-purpose first of the independent arm of whole wind-powered electricity generation be hung in use and be installed in main crane arm head, carry out operation.The whole erection process only needs just once to lift and can realize normal operation, has therefore improved operating efficiency greatly.
Than existing independent arm head mounting structure, parts such as swivel mount, transition segment have been saved, therefore structure is more simplified, parts still less, brachium shortens, it is littler to transport and place shared space, weight is also lighter, and in addition, the truss-like arm head 1 in the crane arm head assembly is owing to adopted truss structure, further lighten on weight, the resistance to compression flexing resistance is stronger.The wind area of arm head of full truss-like own is very little, is subjected to the influence of windage less than the arm head of shell-and-plate.
The weight 6 that will as far as possible avoid steel rope to suspend in midair is interfered with crane arm, the end that assembly pulley is installed on the truss-like arm head 1 is leant out forward with respect to link span assembly 3, form " L " type connection structure between truss-like arm head 1 and the link span assembly 3.The minor details arm 4 that the structure of " forehead " formula that this is overhanging can make the lift heavy steel rope of weight 6 and main crane arm 5 effectively is increasing apart from d2 between the pulley of projection forwardly, than existing independent arm head, then the present invention can avoid weight 6 generations and minor details arm 4 situation of the interference of the pulley of projection forwardly as far as possible.The angle of formed " L " shape can also select other greater than the angle that is fit to of 90 degree according to the actual loading situation about 120 degree between truss-like arm head 1 and the link span assembly 3.
As shown in Figure 5, for the crane arm head assembly of the special-purpose independent arm head embodiment of wind-powered electricity generation of the present invention with surpassed the structural representation of arm-tie assembly.In Fig. 5, can see, the truss-like arm head of crane arm head assembly can specifically comprise two triangular trusses 11 that be arranged in parallel, between two triangular trusses 11, be provided with a plurality of pipe links 12, two groups of angle points 16,15 of two triangular trusses 11 are installed conductor rope pulley 8 and assembly pulley 7 respectively as two ends of truss-like arm head 1 respectively, also be connected with two strut bars 13 on two triangular trusses 11, the 3rd group of angle point 17 of an end 18 of these two strut bars 13 and two triangular trusses 11 is connected with link span assembly 3 respectively.
On the angle point 16 corresponding ends of two triangular trusses 11, also be connected with and surpassed arm-tie assembly 2, having surpassed arm-tie assembly 2 is used for connecting and has surpassed steel rope, to surpass connection location and transfer to fixedly on the auxiliary, can strengthen intensity, lift heavy ability and the stability of independent arm head and main crane arm.
As shown in Figure 6, be the structural representation of the link span assembly of the special-purpose independent arm head embodiment of wind-powered electricity generation of the present invention.In Fig. 6, link span assembly 3 also adopts truss structure, and its size from an end 9 of the minor details arm 4 that connects main crane arm 5 to each cross section of an end 10 that connects truss-like arm head 1 reduces gradually.The version of link span assembly 3 also can be prismatic, and namely the link span assembly is identical to each sectional dimension of an end that connects the truss-like arm head from an end of the minor details arm that connects main crane arm.
The special-purpose independent arm head embodiment of above-mentioned wind-powered electricity generation does not realize the luffing function, refers to realize whole luffing by the amplitude oil cylinder of main crane arm, but as required, can between link span assembly and truss-like arm head luffing mechanism be set yet, and realizes local luffing.
Should be noted that at last: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; And not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
