The specific embodiment

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Wind-powered electricity generation unit is when Assembly &Disassembly, need ultra-large type hoisting crane that certain height, amplitude and very large lifting performance is provided, but this has certain requirement to the performance of main crane arm, height and amplitude, adopt existing independent arm head, Assembly &Disassembly job very difficult, also exist interfere, problem that windage effect is large.

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 the utility model wind-powered electricity generation.In conjunction with the special-purpose independent arm head embodiment of the wind-powered electricity generation shown in Fig. 4, be arranged on the constructional drawing of the crane jib of wind-powered electricity generation operating mode, the special-purpose independent arm head of wind-powered electricity generation in the present embodiment comprises: crane arm head assembly, link span assembly 3 and surpassed arm-tie assembly 2, 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 arranged on respectively two ends of truss-like arm head 1, 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, surpass 2 of arm-tie assemblies and be arranged on the end that conductor rope pulley 8 is installed on truss-like arm head 1, crane arm head assembly and link span assembly 3 on the minor details arm 4 of main crane arm 5 with integral form Assembly &Disassembly.

In the present embodiment, between crane arm head assembly and link span assembly with integral form Assembly &Disassembly, while carrying out Assembly &Disassembly so under wind-powered electricity generation operating mode, operating personal has saved the work to the assembly and disassembly between crane arm head assembly and link span assembly, therefore guaranteed that operating personal can realize fast assembling-disassembling and transportation easily, the operating efficiency of raising operating personal under wind-powered electricity generation operating mode in use.Surpass 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, 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 and be arranged on main crane arm head in use, carry out operation.Whole installation process only need to just once lift and can realize normal operation, has therefore improved greatly operating efficiency.

Than existing independent arm head mounting structure, the parts such as swivel mount, transition segment have been saved, therefore structure is more simplified, and still less, brachium shortens parts, transport and place shared space less, weight is also lighter, and in addition, the truss-like arm head 1 in crane arm head assembly is owing to having adopted truss structure, in weight, further lighten, resistance to compression flexing resistance is stronger.The wind area of arm head of full truss-like own is very little, than the arm head of shell-and-plate, is subject to the impact of windage less.

To avoid the weight 6 that steel rope suspends in midair to interfere with crane arm as far as possible, can also further make the end that assembly pulley is installed on truss-like arm head 1 lean out forward with respect to link span assembly 3, form " L " type connection structure between truss-like arm head 1 and link span assembly 3.The structure of " forehead " formula that this is overhanging can effectively make the lift heavy steel rope of weight 6 and the minor details arm 4 of main crane arm 5 forwardly the distance d2 between the pulley of projection increase, than existing independent arm head, the utility model can be avoided weight 6 generations and minor details arm 4 situation of the interference of the pulley of projection forwardly as far as possible.Between truss-like arm head 1 and link span assembly 3, the angle of formed " L " shape, in 120 degree left and right, can also select other to be greater than the applicable angle of 90 degree according to actual loading situation.

As shown in Figure 5, for the crane arm head assembly of the special-purpose independent arm head embodiment of the utility model wind-powered electricity generation 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 respectively conductor rope pulley 8 and assembly pulley 7 as two ends of truss-like arm head 1 respectively, on two triangular trusses 11, be also connected with two strut bars 13, the 3rd group of angle point 17 of one end 18 of these two strut bars 13 and two triangular trusses 11 is connected with link span assembly 3 respectively.

On the corresponding end of angle point 16 of two triangular trusses 11, be also 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 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 the utility model wind-powered electricity generation.In Fig. 6, link span assembly 3 also adopts truss structure, and it reduces to the size in each cross section of one end 10 of truss frame for connecting formula arm head 1 gradually from connecting one end 9 of the minor details arm 4 of main crane arm 5.The version of link span assembly 3 can be also prismatic, and link span assembly is identical to each sectional dimension of one end of truss frame for connecting formula arm head from connecting one end of minor details arm of main crane arm.

The special-purpose independent arm head embodiment of above-mentioned wind-powered electricity generation does not realize 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.

Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
