Abstract
The utility model discloses a kind of welding ground fastener for pipeline welding, comprise with bolted two blocks of plates that are relatively fixed, described fixed head one end is bent to arc, and the arc tips of two blocks of plates that are relatively fixed is combined as circular arc bayonet socket, and described fixed head is provided with welding ground connector.Welding ground is first connected with welding ground connector by the utility model, the circular arc bayonet socket recycling two pieces of plates formation that are relatively fixed is connected on pipeline, and utilize bolt-locking to fix, thus quick, the stable connection achieving welding ground and pipeline, connect contact surface large, it is fastening firm to connect, and can not cause the destruction of pipe surface coating.
Description
Technical field
The utility model relates to a kind of ground wire and fixes specific purpose tool, is specifically related to a kind of welding ground fastener for pipeline welding.
Background technology
The grounding requirement of welding machine is that welding ground and welding machine and weldment must be fastening firm, and requires welding ground to forbid being connected on and only have in bolted metal structure with weldment, must be connected on welding work pieces.Therefore, welding ground and welding work pieces be connected to become a comparatively stubborn problem, time particularly for pipeline welding, common way welds a wiring drill rod on pipeline, easy like this destruction of causing pipe surface coating, and contact surface is little, and it is fastening not firm to connect.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of welding ground fastener for pipeline welding, can be quick, stable be connected with pipeline by welding ground, and contact surface is large, and it is fastening firm to connect, and can not cause the destruction of pipe surface coating.
For achieving the above object, the utility model provides following technical scheme:
Welding ground fastener for pipeline welding of the present utility model, comprise with bolted two blocks of plates that are relatively fixed, described fixed head one end is bent to arc, and the arc tips of two blocks of plates that are relatively fixed is combined as circular arc bayonet socket, and described fixed head is provided with welding ground connector.
Further, the diameter of described circular arc bayonet socket is 80 ~ 200mm.
Further, described fixed head is zinc-coated flat steel sheet plate.
Further, described welding ground connector is welding ground connecting ring.
Further, described welding ground connecting ring is round steel.
The beneficial effects of the utility model are:
Welding ground is first connected with welding ground connector by the utility model, the circular arc bayonet socket recycling two pieces of plates formation that are relatively fixed is connected on pipeline, and utilize bolt-locking to fix, thus quick, the stable connection achieving welding ground and pipeline, connect contact surface large, it is fastening firm to connect, and can not cause the destruction of pipe surface coating.The circular arc bayonet socket of welding ground fastener of the present utility model according to different calibers adjustment subtended angle, can also be applicable to the pipeline of a fixed-caliber scope.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is main TV structure schematic diagram of the present utility model, Fig. 2 is side-looking structural representation of the present utility model, as shown in the figure, welding ground fastener for pipeline welding of the present utility model, comprise the two blocks of plates 3 that are relatively fixed connected with bolt 2, described fixed head 3 one end is bent to arc, and the arc tips of two blocks of plates 3 that are relatively fixed is combined as circular arc bayonet socket, and described fixed head 3 is provided with welding ground connector 1.
In the present embodiment, by adjustment fixing plate 3 and bolt 2, the diameter of described circular arc bayonet socket can be adjusted to 80 ~ 200mm.
In the present embodiment, described fixed head 3 is zinc-coated flat steel sheet plate.
In the present embodiment, described welding ground connector 1 is welding ground connecting ring, and described welding ground connecting ring is round steel.
The method of operating of the welding ground fastener for pipeline welding of the present utility model:
1) welding ground is connected with welding ground connector 1;
2) adjustment fixing plate 3 and bolt 2, adjust to suitable subtended angle according to caliber by circular arc bayonet socket, is connected on pipeline by circular arc bayonet socket;
3) adjusting bolt 2 is locked.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
