The invention discloses a kind of submerged-arc welding earth wire clamp, including the contact rod being connected with ground wire, in addition to it is fixed on by the elastic support unit of welded tube body side, described elastic support unit applies elastic force and drives contact rod all the time with being contradicted by welded tube body.Elastic support unit is fixed on by welded tube body side, contact rod is connected with ground wire, elastic support unit applies elastic force to contact rod makes contact rod contradict all the time on by welded tube body, during being rotated by welded tube body on rolling wheel support, contact rod can keep with by the contact of welded tube body, so that it is guaranteed that the stabilization of ground wire, it is ensured that stable welding current is so as to ensure welding quality.
Description
Technical field
The invention belongs to welding technology field, more particularly to a kind of submerged-arc welding earth wire clamp.
Background technology
Submerged-arc welding is that a kind of electric arc burns the method welded under welding flux layer.Its intrinsic welding quality stable, weldering
Yield of delivering a child is high, without arc light and the advantages of seldom flue dust, becomes the important steel such as pressure vessel, pipeline section manufacture, box beam column
Main welding method in structure fabrication.Carrying out last one of girth welding technique of the tubular products such as pressure vessel, drum
When, it is that will be placed on the rolling wheel support being arranged symmetrically to carry out arc welding by welded tube body, quilt is reconnected using earth wire clamp ground wire
Welded tube body ensures that welding machine provides stable welding current, so as to ensure welding quality.In the prior art, earth wire clamp is clamped in and welded
Body end edge is realized to be rotated in connection, welding process by welded tube body under the drive of roller, and earth wire clamp is followed by welded tube body
Rotate, ground wire can be wrapped on earth wire clamp, earth wire clamp pulls generation loosening by ground wire or ground wire is pullled by earth wire clamp and departs from ground,
At this moment welding current will be caused unstable, so that occurring spark phenomenon causes to be welded tube surfaces burn.
The content of the invention
It is an object of the invention to provide a kind of submerged-arc welding earth wire clamp, contacted all the time with by welded tube body in welding process,
Earth wire winding is avoided around earth wire clamp, it is ensured that welding current is stable.
To achieve these goals, the present invention takes following technical scheme：A kind of submerged-arc welding earth wire clamp, including connect with ground wire
The contact rod connect, in addition to be fixed on by the elastic support unit of welded tube body side, described elastic support unit applies elastic force
Contact rod is driven all the time with being contradicted by welded tube body.
In above-mentioned technical proposal, elastic support unit is fixed on by welded tube body side, and contact rod is connected with ground wire, elasticity branch
Support unit applies elastic force to contact rod makes contact rod contradict all the time on by welded tube body, is rotated by welded tube body on rolling wheel support
During, contact rod can keep with by the contact of welded tube body, so that it is guaranteed that the stabilization of ground wire, it is ensured that stable welding current
So as to ensure welding quality.
Brief description of the drawings
Fig. 1 installs for the present invention coordinates front view；
Fig. 2 is schematic perspective view of the present invention.
Embodiment
Made further instructions with reference to accompanying drawing 1,2 couples of present invention：
A kind of submerged-arc welding earth wire clamp, including the contact rod 10 being connected with ground wire, in addition to be fixed on by welded tube body A sides
Elastic support unit 20, described elastic support unit 20 applies elastic force driving contact rod 10 all the time with being contradicted by welded tube body A.Bullet
Property support unit 20 is fixed on by welded tube body A sides, and contact rod 10 is connected with ground wire, and elastic support unit 20 is applied to contact rod 10
It is conductive during being rotated by welded tube body A on rolling wheel support B plus elastic force makes contact rod 10 contradict all the time on by welded tube body A
Rod 10 can keep with by welded tube body A contact, so that it is guaranteed that the stabilization of ground wire, it is ensured that stable welding current is so as to ensureing
Welding quality.
