[0002] During the welding of insulated pipes, a grounding device is used to connect the pipes to the ground to ensure safety. The main purpose of grounding is to conduct static electricity, leakage current, or fault current that may be generated during welding to the ground, preventing electric shock hazards and equipment damage. However, when welding insulated pipes, the grounding wire can only be placed at the pipe joint; an excessively long grounding wire can easily interfere with normal welding operations. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a grounding device for welding insulated pipes is provided to solve the problem that the grounding wire can only be placed at the pipe joint during welding of insulated pipes, and that an excessively long grounding wire can easily affect normal welding operations.

[0004] To achieve the above objectives, a grounding device for welding insulated pipes is provided, comprising: an arc-shaped support plate, wherein an insulated pipe body is disposed at the lower end of the arc-shaped support plate.

[0005] The upper end of the arc-shaped support plate is supported by a tiger clamp via a fixed column. The inner side of the tiger clamp is pressed and held by a strip steel plate by fastening bolts. A grounding stud is connected through the left end of the strip steel plate. An arc-shaped clamp is axially connected to the front end of the arc-shaped support plate via a first connecting plate. An adjusting column is threaded through the surface of the arc-shaped clamp. A positioning pressure plate is connected to the side end of the adjusting column by a bearing. The side of the positioning pressure plate is in close contact with the insulation pipe body via a rebound rubber pad. A magnetic seat is embedded in the surface of the arc-shaped support plate.

[0006] Furthermore, a copper lug is installed on the upper arc surface of the arc-shaped support plate by a fixing stud, and a grounding wire is connected to the surface of the copper lug.

[0007] Furthermore, a second connecting plate is welded to the rear end of the arc-shaped support plate, and the upper surface of the second connecting plate is fastened to the arc-shaped fastener by a snap fastener.

[0008] Furthermore, the lower arc surface of the arc-shaped support plate is bonded with an anti-slip pad; and the arc-shaped support plate is attached to the outer surface of the insulation pipe.

[0009] Furthermore, a pipe interface end is provided on the side end of the insulation pipe body, and a grounding stud is in contact with the surface of the pipe interface end.

[0010] Furthermore, the grounding stud surface is fixed to the strip steel plate by nuts; and the nuts are screwed onto the upper and lower surfaces of the strip steel plate.

[0011] Furthermore, the arc-shaped clip is a U-shaped metal piece; and the clip is located at the outer end of the insulation pipe body.

[0012] The beneficial effects of this utility model are as follows: the grounding device for welding insulated pipes utilizes an arc-shaped support plate, an arc-shaped clamp, a positioning pressure plate, a rebound rubber pad, an adjusting column, and a magnetic base to form a clamping and positioning structure for the grounding device. The arc-shaped support plate is attracted to the surface of the insulated pipe by the magnetic base, so that the grounding stud connected to the side end of the arc-shaped support plate is fixed at the weld joint of the insulated pipe. At the same time, the positioning pressure plate on the inner side of the arc-shaped clamp provides stable support on the surface of the insulated pipe, realizing the indirect connection between the grounding stud and the wiring wire. This facilitates quick and easy fixing and installation of the welding grounding device, and makes it easy for the wiring wire to deviate from the weld joint of the pipe, avoiding the wiring wire from loosening or detaching due to welding operations. This ensures the grounding stability of the welding grounding device for insulated pipes and improves the practical performance of the welding grounding device for insulated pipes.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a grounding device for welding insulated pipes, including: an arc-shaped support plate 1, with an insulated pipe body 2 disposed at the lower end of the arc-shaped support plate 1.

[0019] The upper end of the arc-shaped support plate 1 is supported by a tiger clamp 32 through a fixed column 33. The inside of the tiger clamp 32 is pressed and held by a strip steel plate 31 through a fastening bolt 35. A grounding stud 3 is connected through the left end of the strip steel plate 31. The front end of the arc-shaped support plate 1 is axially connected to an arc-shaped clamp 4 through a first connecting plate 13. An adjusting column 43 is screwed through the surface of the arc-shaped clamp 4. A positioning pressure plate 41 is connected to the side end of the adjusting column 43 by a bearing. The side of the positioning pressure plate 41 is tightly attached to the heat insulation pipe body 2 through a rebound rubber pad 42. A magnetic seat 6 is embedded in the surface of the arc-shaped support plate 1.

[0020] When installing the grounding device on the insulation pipe body 2, first, snap the arc-shaped support plate 1 onto the surface of the insulation pipe body 2, and then make the grounding stud 3 contact the pipe interface end 21 of the insulation pipe body 2. Then, rotate the arc-shaped clamp 4 so that the rear end of the arc-shaped clamp 4 is engaged with the arc-shaped support plate 1. Next, rotate the adjusting column 43 so that the multiple positioning pressure plates 41 on the inner side of the arc-shaped clamp 4 are pressed and supported between the arc-shaped clamp 4 and the insulation pipe body 2. Finally, connect the connecting wire to the arc-shaped support plate 1 to complete the installation and fixing of the grounding device.

[0021] In this embodiment, a copper lug 11 is installed on the upper arc surface of the arc-shaped support plate 1 via a fixing stud 12, and a grounding wire 5 is connected to the surface of the copper lug 11. A second connecting plate 14 is welded to the rear end of the arc-shaped support plate 1, and the upper surface of the second connecting plate 14 is fastened to the arc-shaped clip 4 via a snap fastener 15. An anti-slip pad 16 is adhered to the lower arc surface of the arc-shaped support plate 1; and the arc-shaped support plate 1 is attached to the outer surface of the insulation pipe body 2.

[0022] As a preferred embodiment, the copper lug 11 facilitates the connection between the arc-shaped support plate 1 and the grounding wire 5, so that the insulation pipe body 2 is indirectly connected to the grounding wire 5 through the grounding stud 3 and the arc-shaped support plate 1. This facilitates the grounding wire 5 being offset from the pipe welding point, preventing the grounding wire 5 from affecting the welding operation, and at the same time avoiding the grounding wire from being easily loosened or disconnected due to the welding operation, thus ensuring the grounding stability of the insulation pipe welding grounding device.

[0023] In this embodiment, a pipe interface end 21 is provided on the side end of the insulation pipe body 2, and a grounding stud 3 is in contact with the surface of the pipe interface end 21. The surface of the grounding stud 3 is fixed to the strip steel plate 31 by nuts 34; and the nuts 34 are screwed together on the upper and lower surfaces of the strip steel plate 31.

[0024] In a preferred embodiment, the grounding stud 3 facilitates the conduction of static electricity at the pipe interface end 21 to the grounding wire 5 via the arc-shaped support plate 1. The nut 34 facilitates the adjustment of the connection position between the grounding stud 3 and the strip steel plate 31, ensuring that the grounding stud 3 can contact the surface of the pipe interface end 21 of the insulation pipe body 2.

[0025] In this embodiment, the arc-shaped clip 4 is a U-shaped metal piece; and the clip is located at the outer end of the insulation pipe body 2.

[0026] As a preferred implementation, the U-shaped arc-shaped clamp 4 facilitates further reinforcement of the arc-shaped support plate 1, ensuring that the arc-shaped support plate 1 does not loosen or shift under the dual fixing action of the magnetic base 6 and the arc-shaped clamp 4, thus ensuring the stable guidance of electrostatic current to the ground during the welding process and eliminating the harm of electrostatic to the welding equipment.

[0027] This utility model of a grounding device for welding insulated pipes effectively solves the problem that the grounding wire can only be placed at the pipe joint during welding of insulated pipes, and that an excessively long grounding wire can easily affect normal welding operations. It realizes the indirect connection between the grounding stud and the wiring wire, which facilitates quick and easy fixing and installation of the welding grounding device. It also allows the wiring wire to be offset from the pipe welding point, avoiding the wiring wire from loosening or detaching due to welding operations. This ensures the grounding stability of the grounding device for welding insulated pipes and improves its practical performance. It is applicable to grounding devices for welding insulated pipes.
