Abstract
The utility model relates to a welded earthing device for a wind power generation tower tube. The device comprises a fixed base, two symmetrical brackets and graphite sheets, wherein a fixed lifting lug is arranged on the fixed base; connecting holes matched with the fixed lifting lug are formed at the bottom ends of the two symmetrical brackets, and are connected with the fixed lifting lug; graphite sheet clips with the graphite sheets fixed thereon are respectively arranged at the top ends of the two symmetrical brackets; and a spring is connected between the two symmetrical brackets. The welded earthing device provided by the utility model has simple structure and convenience in use, not only is free from the affection of a rotation angle of the wind power generation tower tube, but also can ensure the favorable contact between the ground and the wind power generation tower tube, and improves the earthing electric conduction quality.
Description
Technical field
The utility model relates to the wind power tower drum manufacturing and uses the frock field, relates in particular to wind power tower drum welding earthing device.
Background technology
At present; The wind-power tower circumferential weld adopts the Lincoln weld welding, and the tower tube rotates on turning rolls, and ground connection is to produce the requisite part of electric arc; Usually adopt flexible cable directly to be connected with the tower drum flange bolt hole; Cause cable " to beat and twist " phenomenon because the tower tube rotates continuously, cable is destroyed, and cable loss is big.
The utility model content
The utility model technical problem to be solved provides a kind of wind power tower drum simple in structure, easy to use welding earthing device.
For addressing the above problem, the described wind power tower drum of the utility model welds earthing device, and it is characterized in that: this device comprises the support and the graphite flake of firm banking, two symmetries; Said firm banking is provided with fixedly hanger; The bottom of the support of said two symmetries is provided with the connecting hole that is complementary with said fixedly hanger, and links to each other with said fixedly hanger through this connecting hole; The top of the support of said two symmetries is respectively equipped with the graphite flake folder, is fixed with said graphite flake on this graphite flake folder; Be connected with spring between the support of said two symmetries.
The bottom of the support of said two symmetries links to each other with said fixedly hanger through the bearing pin that passes said connecting hole.
Said graphite flake folder is fixed together through bolt and said graphite flake.
The utility model compared with prior art has the following advantages:
1, owing to the utility model contacts graphite flake through spring with wind-power tower; Form sliding contacting mode, replaced traditional cable directly to be fixed on the mode on the wind-power tower flange, therefore; Not only do not receive the influence of the wind-power tower anglec of rotation; And can guarantee that ground connection contacts with the good of wind-power tower, improve ground connection conduction quality, thereby avoided causing arc scratch.
2, owing to the graphite flake in the utility model is fixed on the graphite flake folder through the bolt mode of holding out against, therefore, when the graphite flake serious wear, can the easy disassembly graphite flake.
3, because the firm banking in the utility model is transportable, therefore, the utility model can use in different job locations, thereby having avoided repeating makes.
4, owing to use spring to connect in the utility model, therefore, can satisfy the demand of different-diameter wind-power tower welding.
5, the utility model is simple in structure, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is that the facade of the utility model is arranged sketch map.
Among the figure: 1-wind-power tower 2-firm banking 3-is hanger 4-bearing pin 5-graphite flake 6-graphite flake folder 7-spring 8-support fixedly.
Embodiment
As shown in Figure 1, wind power tower drum welding earthing device, this device comprise the support 8 and the graphite flake 5 of firm banking 2, two symmetries.
Firm banking 2 is provided with fixedly hanger 3; The bottom of the support 8 of two symmetries is provided with and the fixing connecting hole that is complementary of hanger 3, and links to each other with fixing hanger 3 through this connecting hole; The top of the support 8 of two symmetries is respectively equipped with graphite flake folder 6, is fixed with graphite flake 5 on this graphite flake folder 6; Be connected with spring 7 between the support 8 of two symmetries.
Wherein: the bearing pin 4 of the bottom of the support 8 of two symmetries through passing connecting hole links to each other with fixing hanger 3.
Graphite flake folder 6 is fixed together through bolt 9 and graphite flake 5.
During use, the graphite flake in the utility model 5 contacted it well with wind-power tower 1 through spring 7 get final product.
