Drawings
FIG. 1 is a schematic front view of the present invention;
FIG. 2 is a left side view of the present invention;
FIG. 3 is a schematic top view of the present invention;
wherein: 1-reinforcing steel bars; 2-a nut; 3-a bolt; 4-arc plate.
Detailed Description
The utility model is further explained with reference to the accompanying drawings.
As shown in the figure, a be used for long defeated pipeline welded welding machine earthing tool, including arc 4, the internal diameter of arc 4 matches with the external diameter of pipeline, and the top central point of arc 4 puts and is connected with reinforcing bar 1 that one end is equipped with the crotch, and reinforcing bar 1 is perpendicular with the tangent line of arc 4, and reinforcing bar 1 is equipped with the bolt 3 that is used for being connected with the welded earth connection for a side surface of arc 4, is equipped with the nut 2 that matches with bolt 3 on bolt 3.
The arc-shaped plate is connected with one end of the straight section of the steel bar, the bolt is welded in the middle of the steel bar to form an arc-shaped structural part, the bolt is used for connecting a welded grounding wire, and one end of the steel bar with the hook is tightly attached to the welding parent metal, so that the grounding end is firmly and tightly connected with the pipeline.
The arc is formed by steel plate according to the external diameter size processing of pipeline, and the steel plate laminating is in the pipeline, therefore the circular arc internal diameter that the arc formed equals the pipeline external diameter.
The manufacturing method of the utility model is as follows:
1. shearing a steel plate with the width of 80mm and the thickness of 10mm, wherein the length is determined by the diameter of the pipeline;
2. processing the sheared steel plate into an arc shape attached to the pipeline according to the outer diameter of the pipeline;
3. manufacturing a reinforcing steel bar with the diameter of 20mm and the length of 500mm, manufacturing a 90-degree hook at one end of the reinforcing steel bar, welding M10 x 50mm bolts on the pipeline back at the middle of the reinforcing steel bar, and matching nuts;
4. and welding one end of the straight section of the steel bar and the middle of the arc-shaped member together to form a required structural member, and finishing the manufacturing.
The using method of the utility model is as follows:
1. connecting the bolt of the structural member with the grounding wire of the welding machine firmly;
2. placing the hook part of the structural part above the joint of the two pipelines by about 100mm, and tightly attaching;
3. starting welding operation;
4. and removing the grounding tool until the welding is completed.
