Description
Technical field
The utility model is related to a kind of composite die, specifically a kind of wind turbine tower circular seam submerged arc welding ground wire with rotation
Change a job the attachment means of part.
Background technology
Wind energy is increasingly paid attention to as a kind of regenerative resource of cleaning by countries in the world.Its amount of accumulateing is huge, the whole world
Wind energy be about 2.74 × 109MW, wherein available wind energy be 2 × 107MW, than the water energy total amount that can be developed on the earth
Also want big 10 times.Wind is utilized very early by people, is mainly drawn water by windmill, flour milling etc., and present, and people are interested
It is how to use wind to generate electricity, the principle of wind-power electricity generation is to drive air vane rotation using wind-force, then will be revolved by booster engine
The speed for turning is lifted to promote electrical power generators.According to the technology of current wind-power electricity generation, about three meters per second of gentle breeze
Speed, just can start to generate electricity.Wind-power electricity generation is just forming in the world one upsurge, because wind-power electricity generation does not have fuel problem,
Also radiation or air pollution will not be produced.
With flourishing for wind-power electricity generation, wind electricity blade is endlessly transported to wind field all over the world from manufacturer.Mesh
Before, most of tower drum of wind tower presents increasing, higher and higher trend.Tower drum of wind tower is the weight for constituting wind power plant
Part is wanted, is mainly used in supporting wind blade and generating set, generally adopted by the segmentation after steel plate edge rolling in the industry at present,
Formed using submerged-arc welding butt welding.Because being limited the characteristics of submerged-arc welding, real-time welding position needs to be placed on horizontal level, tower
Segmentation is hollow cylinder, it is therefore desirable to constantly rotate tower to ensure downhand position.And the ground wire of welding machine needs direct and workpiece
Contact, at present, generally using ground wire by rotation external member and fixture and the method for cylinder connection, but often due to rotation external member is led
The contact area introductory note of electricity plays heating problem and arc damage, clamping stagnation between sleeve and axle is caused, in thus resulting in rotation process
The winding problem of ground wire, puzzlement is caused to practical operation, cannot guarantee that stablizing for welding current voltage, the life-span of attachment means
It is low.
In prior art, because existing rotary connector is connected by an axle with c-type, between axle sleeve and axle actually
A kind of linear contact lay, contact area very little, resistance is very big, cause heating problem, electric arc to wound and because heating and electric arc wound and bring
Axle sleeve and axle between it is relative slide difficult, the winding problem of rotation process center line is to reality between the axle sleeve for subsequently resulting in and axle
Operation causes puzzlement, cannot guarantee that stablizing for welding current voltage, as shown in Figure 1.
Utility model content
Utility model purpose：The purpose of this utility model is, in order to solve the deficiencies in the prior art, to be particularly directed to heating
Problem, electric arc are wounded, the winding problem of rotation process center line causes puzzlement to practical operation, cannot guarantee that welding current voltage
Stable problem.The attachment means of a kind of wind turbine tower circular seam submerged arc welding ground wire and rotational workpieces, more section are invented
It is reasonable to learn, and increased contact area, reduces contact resistance, it is ensured that welding current, voltage are stablized, and reduce welding machine output heating
Loss, rotation ground wire connector will not generate heat damage.
Technical scheme：In order to realize object above, a kind of wind turbine tower circular seam submerged arc welding described in the utility model
The attachment means of ground wire and rotational workpieces, it includes：Limit switch, c-type grip module, ground wire, axle, carbon brush component, connection
Sleeve member and copper dish, the side of described copper dish is fixed with carbon brush component, and copper dish are fixed in connecting shaft external member.
It it is 4 groups as the quantity of of the present utility model further preferred, described carbon brush component.
As it is of the present utility model further preferably, the carbon brush on described carbon brush component is contacted with copper dish and offseted.
It is copper graphite carbon brush as of the present utility model further preferred, described carbon brush, using copper graphite carbon brush external member
Increased the conductive contact area of ground wire.
Beneficial effect：A kind of wind turbine tower circular seam submerged arc welding ground wire that the utility model is provided and rotational workpieces
Attachment means, compared with prior art, with advantages below：
1st, service life is increased, experimental data shows, the life-span of the prior art is up to 3 months, using this practicality
Can be using up to 1 year after new；
2nd, reduce ground wire and change the frequency, increased the convenience of operation；
3rd, increase Product jointing quality stability, improve the quality of product；
4th, production cost is saved.
Description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is further elucidated.
As shown in Fig. 2 a kind of wind turbine tower circular seam submerged arc welding ground wire described in the utility model and rotational workpieces
Attachment means, it includes：Limit switch 1, c-type grip module 2, ground wire 3, axle 4, carbon brush component 5, connecting shaft external member 6 and copper
Disk 7.
Embodiment
The utility model is installed first, carbon brush component 5 is first fixed on the side of connecting shaft external member 6, make on carbon brush component 5
Copper graphite carbon brush contact and offset with the copper dish 7 in connecting shaft external member 6, ground wire 3 is fixed on the bottom of connecting shaft external member 6, even
Spindle external member 6 is fixed on c-type grip module 2 by axle 4, and limit switch 1 is arranged on c-type grip module 2.
When using the utility model, after tower is kept flat, c-type grip module 2 is clipped on the thickness direction of tower,
When tower is rotated, c-type grip module 2 follows tower to rotate, and carbon brush component 5 is by 4 groups of carbon brush and copper dish in connecting shaft external member 6
7 realize that face contact is conductive, and compared with original mode contact area is increased, and reduce contact resistance, it is ensured that voltage x current is stable.
Above-mentioned specific embodiment only to illustrate technology design of the present utility model and feature, its objective is to allow and be familiar with the skill
