Background technology
Wind energy more and more is subjected to the attention of countries in the world as a kind of inexhaustible, nexhaustible regenerative resource, and wind power generation is all being greatly developed in countries in the world at present, makes every effort to protect environment, realizes the low-carbon (LC) life.
Windmill tower frame is the important composition parts of wind turbine generator, and it will support the weight in nearly hundred tons in wind wheel and cabin, and bears normal pressure and the tilting moment of strong wind to wind wheel, cabin, pylon.So the quality that improves pylon longitudinal seam and circumferential welded seam is seemed very important.The cylindrical shell group must use Lincoln weld to weld at horizontal level to the splicing circumferential welded seam.Like this, cylindrical shell just need be placed on the turning rolls and slowly rotate, and the welding head of automatic arc welding should be in the top of cylindrical shell circumference and carry out Lincoln weld, could satisfy at horizontal level like this and weld.
In Lincoln weld, the ground wire cable connects power cathode, and welding machine cable connects positive source, and they form a current circuit.The welder is bonding of earth cable line one end welding, and then bonding is welded on the cylindrical shell as the cable of current reflux, and this is that weld procedure specification institute is unallowed.Welding process requirement: avoid damaging mother metal during welding, particularly do not allow to carry out striking, weld handle or earth connection parts etc. temporarily in the non-welding position of flange.There is following shortcoming in welding termination before: electric current is very big during owing to welding, generally more than 600 amperes, causes the heating of earth cable line, burning, has disaster hidden-trouble; The ground wire of interim welding or do not have fixedly connected ground wire damage mother metal; Cable useful life is shortened in cable distortion.
Summary of the invention
Technical problem to be solved by this invention provides a kind of whirligig that is used to utilize flange bolt hole connection welding earth connection, and the safe class when it has improved welding has also guaranteed welding quality.
For solveing the technical problem, the invention provides a kind of whirligig that is used to utilize flange bolt hole connection welding earth connection, it is characterized in that, the whirligig that is used to utilize the flange bolt hole to connect the welding earth connection comprises pressing plate, the conduction copper sheathing, the conductive copper axle, connecting bolt, nut, pad, connecting screw rod, disk spring, check ring, pressing plate covers the conductive copper cover, check ring, disk spring is located between pressing plate and the conduction copper sheathing, make pressing plate compress disk spring and conduction copper sheathing by tighting a bolt, one side end face of conduction copper sheathing and conductive copper axle fits tightly, connecting bolt is connected with the conductive copper male thread, packing ring is located between connecting bolt and the conductive copper axle, connecting screw rod and conductive copper axle are fixed, nut is installed in the two ends of connecting screw rod, and pad is located at the inboard of nut.
Preferably, the described whirligig that is used to utilize the flange bolt hole to connect the welding earth connection also comprises packing ring, and packing ring is located between connecting bolt and the conductive copper axle.
Positive progressive effect of the present invention is: the present invention can prevent the earth cable distortion, even the hidden danger of breaking out of fire, and has guaranteed that the flange base metal does not damage, and the safe class when having improved welding has also guaranteed welding quality.

Embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the whirligig that the present invention is used to utilize the flange bolt hole to connect the welding earth connection comprises pressing plate 1, conduction copper sheathing 2, conductive copper axle 3, connecting bolt 4, packing ring 5, nut 6, pad 7, connecting screw rod 8, check ring 9, disk spring 10, tight a bolt 11, pressing plate 1 covers conduction copper sheathing 2, check ring 9, disk spring 10 is located between pressing plate 1 and the conduction copper sheathing 2,11 make pressing plate 1 compress disk spring 10 and conduction copper sheathing 2 by tighting a bolt, one side end face of conduction copper sheathing 2 and conductive copper axle 3 fits tightly, connecting bolt 4 is threaded with conductive copper axle 3, packing ring 5 is located between connecting bolt 4 and the conductive copper axle 3, connecting screw rod 8 is fixing with conductive copper axle 3, nut 6 is installed in the two ends of connecting screw rod 8, and pad 7 is located at the inboard of nut 6.Tight a bolt 11 the degree of tightening of control, the copper sheathing 2 that both guaranteed to conduct electricity is firm with the end face subsides of conductive copper axle 3, the copper sheathing 2 that can guarantee again to conduct electricity rotates on conductive copper axle 3, and the big electric current when welding like this is back to power cathode by conductive copper axle 3 through conduction copper sheathing 2 and earth cable.
Shown in Fig. 2 and 3, welding head 14 is above tower tube 15, tip is aimed at the welding position exactly, tower tube 15 is placed on the rotatable turning rolls 16, connecting screw rod 8 is inserted in the flange bolt hole 13 of tower tube, tighten the nut 6 of flange bolt hole 13 two end faces, be used in the whirligig that utilizes the flange bolt hole to connect the welding earth connection and be fixed on the flange.When welding cylindrical shell circumferential weld, the rotation slowly of tower tube, the whirligig that is used to utilize the flange bolt hole to connect the welding earth connection also rotates thereupon at leisure, but the conduction copper sheathing and the conductive copper axle that are used for utilizing the flange bolt hole to connect the whirligig of welding earth connection relatively rotate again, thereby guarantee that earth cable is in vertical position all the time, prevented the earth cable distortion, even the danger that twists off.
Welding wire in the welder head is anodal, big electric current by welding wire, flange, be used to utilize the flange bolt hole to connect the whirligig and the earth cable of welding earth connection, earth cable is a negative pole.Because it is big to be used to utilize the flange bolt hole to connect the whirligig and the flange contact facings that weld earth connection, the axle that is used for utilizing the flange bolt hole to connect the whirligig of welding earth connection is copper material with cover, conduction and good heat conductivity, thus guarantee that earth cable can excessive heating and burn.The whirligig that the present invention is used to utilize the flange bolt hole to connect the welding earth connection is fixed by adjusting screw(rod) and flange, and it does not injure the flange base metals.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these execution modes.Therefore, protection scope of the present invention is limited by appended claims.
