Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides a be used for pipeline welded ground wire clamping device, including chain 3, quick plug 4, fastening seat 5 and spring 6, as shown in fig. 1-5, riser one 12 is "U" template, and riser two 13 is "H" template.

The two ends of the fastening seat 5 are respectively welded with a first vertical plate 12 and a second vertical plate 13, the first vertical plate 12 is hinged with an adjusting screw 8 through a positioning screw 10, the adjusting screw 8 is clamped in an upper end groove of the H-shaped second vertical plate 13 and is fixedly arranged on the fastening seat 5 through an adjusting nut 11, the middle part of the adjusting screw 8 is welded with a lantern ring 7, one end of a spring 6 is sleeved on the lantern ring 7, the other end of the spring is connected with one end of a first chain 3-1, the other end of the first chain 3-1 is fixedly connected with one side of a quick plug 4, a second chain 3-2 is fixedly connected with the other side of the quick plug 4, the other end of the second chain 3-2 is fixedly arranged in a lower end groove of the first vertical plate 12 through a chain fixing bolt 9, and the two chains and the quick plug 4 encircle the pipeline 1 to be tested and are tightly held through the spring 6; the quick plug 4 is connected with a ground wire 2.
