Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
See Fig. 2, show the flange arrangement of the link 1 that the utility model embodiment provides.As shown in the figure, the flange arrangement of this link 1 mainly comprises the first flanged plate 21 and the second flanged plate 22 be soldered on link 1.First flanged plate 21 is covered on the end of link 1, and the second flanged plate 22 parallels with the first flanged plate 21, and to be separated by preset pitch with the first flanged plate 21, the first flanged plate 21 with the second flanged plate 22 is provided with relative in bolt mounting holes 23.Outer side surface 210 formation of the first flanged plate 21 is used for the surface of contact fitted with the flange arrangement of other links, and the outer side surface of the second flanged plate 22 forms the confined planes be used for the nut screw connection on the head of bolt 6 or bolt 6.It should be noted that, in the utility model embodiment, the outer side surface 210 of the first flanged plate 21 refers to its side deviating from the second flanged plate 22, and the inner side surface of the first flanged plate 21 refers to it just to the side of the second flanged plate 22; In like manner, the outer side surface of the second flanged plate 22 refers to its side deviating from the first flanged plate 21, and the inner side surface of the second flanged plate 22 refers to it just to the side of the first flanged plate 21.
In conjunction with reference to figure 3, when link 1 and link (being also other links) 5 are by Flange joint, the outer side surface 210 of the first flanged plate 21 fits together with the flange arrangement of link 5, bolt 6 is located in the bolt mounting holes 23 on the second flanged plate 22, first flanged plate 21 and the bolt mounting holes on link 5, link 1 and link 5 is detachably connected.As can be seen from Fig. 3 and Fig. 4, the flange arrangement of link 5 is preferably identical with the flange arrangement of link 1, and certainly, in other embodiments, the flange arrangement on link 5 can also adopt known structure of the prior art, does not repeat them here.
The flange arrangement of the link adopting the present embodiment to provide, first flanged plate 21 and the second flanged plate 22 are separated by preset pitch, for increasing the clamp distance of bolt 6, be equivalent to the field of load increasing bolt 6, like this, without the need to arranging bolt cushion cover on bolt 6, the stressed concentration phenomenon of bolt 6 effectively can be improved, reach the effect strengthening bolt 6 fatigue strength, and there is the advantage that structure is simple, cost is low.
Come again see Fig. 2 and Fig. 4, preferably, gusset 3 is connected with between the first flanged plate 21 and the second flanged plate 22, gusset 3 can weld together with the first flanged plate 21, second flanged plate 22, link 1, or only weld together with the first flanged plate 21, second flanged plate 22, to strengthen the intensity of this flange arrangement body.Like this, the first flanged plate 21, second flanged plate 22 can select the sheet material of thinner thickness, is conducive to alleviating weight of equipment, reducing costs.Preferably, gusset 3 is multiple, and multiple gusset 3 and the first flanged plate 21, second flanged plate 22 form lattice box-structure more than, are more conducive to the raising of flange arrangement bulk strength.
Preferably, in conjunction with reference to figure 3 and Fig. 4, because the flange arrangement of the first flanged plate 21 and link 5 fits together, not easily deform, the thickness of the first flanged plate 21 can be less than the thickness of the second flanged plate 22, to reduce cost of material further.
Preferably, the inner side surface of the first flanged plate 21 welds with link 1, forms a weld seam; Inner side surface and the outer side surface of the second flanged plate 22 all weld with link 1, form two weld seams.When flange arrangement under tension or pressure, three weld seams always have a under tension effect, two effects of being under pressure, thus optimize the stress form of weld seam between flange arrangement and link 1, and weld seam is not easy to crack.Like this, also just not be used on the first flanged plate 21, second flanged plate 22 and mill out the fixed hole coordinated with link 1, save machining cost and time, reduce welding difficulty, the requirement of welding procedure and welder being welded to technical ability is also minimized.
Also show a kind of preferred structure of link 1 in the present embodiment, as shown in the figure, link 1 comprises the first side plate 11 and the second side plate 12 be oppositely arranged, and the web 13 be connected with the first side plate 11, second side plate 12 respectively.First side plate 11 and the second side plate 12 may be used for installing other equipment, and preferably, the first side plate 11 and the second side plate 12 parallel, web 13 and the perpendicular setting of the first side plate 11.As can be seen from Figure, first flanged plate 21 lid is located on the end of the first side plate 11, second side plate 12, web 13, second flanged plate 22 is positioned at the space that the first side plate 11, second side plate 12 and web 13 surround, first flanged plate 21, second flanged plate 22 can all weld with the first side plate 11, second side plate 12 and web 13, makes the connection of flange arrangement and link 1 more reliable.
It should be noted that, in the utility model above-described embodiment, the flanged plate parallel to each other be soldered on link 1 is two, be respectively the first flanged plate 21, second flanged plate 22, be appreciated that in other embodiments, the number of flanged plate can also be two or more, two often adjacent flanged plates are all separated with spacing, and bolt 6 is located in the bolt mounting holes of each flanged plate.Flanged plate is substantially identical with above described technique effect for the technique effect that can reach during two or more, does not repeat them here.
It should be noted that in addition, although the first flanged plate 21 is preferably located in the end of link 1 in the present embodiment, in other embodiments, the setting position of the first flanged plate 21 can be arranged according to design requirement, is not limited to the end of link 1.
The utility model embodiment still provides a kind of link, and this link is provided with the flange arrangement of above-mentioned link, and this link press span can be any component needed by Flange joint.The flange arrangement of the link provided because of the utility model embodiment can reach above-mentioned technique effect, and the link being provided with this flange arrangement also should possess corresponding technique effect, does not repeat them here.
The utility model embodiment still provides a kind of Wind turbines, and this Wind turbines comprises generator and the underframe for supporting generator, and underframe comprises above-mentioned link.Particularly, underframe usually to be assembled by the mode of Flange joint by front underframe, rear underframe and is formed, and any one in front underframe, rear underframe can use as above-mentioned link, and configures above-mentioned flange arrangement.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
