Abstract
The electric welding grounding clamp fastening device is applied to electric welding construction. Is characterized in that: a plug is welded at one end of the steel pipe, an external thread connector is fixed on the plug, and a ground wire plate is welded on the outer end face of the external thread connector; the outer wall of the steel pipe is provided with two screw holes which are arranged side by side; and a screw is respectively fixed in the two screw holes. A cuboid gasket is arranged in the steel pipe, and the end parts of the two screws are pressed on the upper part of the gasket; and a copper wire is penetrated from the other end of the steel pipe, and the end part of the copper wire is arranged at the lower part of the gasket. The effect is as follows: the copper conductor can be compressed, the virtual connection phenomenon of the ground wire can not be generated, and the electric welding construction quality is improved. The ground wire is prevented from being frequently adjusted by workers, and the construction efficiency is improved.
Description
Technical field
The utility model relates to electric welding equipment technology field, particularly a kind of electric welding ground connection clamp fastener.
Background technology
The fastener of the electric welding clamp in the various arc welding methods has important effect to the welding construction quality.Electrode arc welding SMAW is that the most square a kind of welding method is still used in development the earliest, at present in the various arc welding methods.SMAW equipment is simple, light, flexible operation, and the welding of the short seam in being applied to keep in repair and assemble particularly can be used for the welding at unapproachable position.In the oil gathering and transportation pipelines construction, adopt SMAW more than 95%, and welding tooling plays an important role to the welding construction quality.
In the pipeline welding process, often weld the defectives such as pore, slag inclusion, undercut.Weld defect tends to cause stress to concentrate, and reduces bearing capacity, reduction of service life, even cause brittle failure.Fastening in bad order in part because of the welding ground joint, there is the virtual connection situation, so that the electric welding machine ground wire causes damage in various degree, fracture has affected welding quality and manufacturing schedule.
The connected mode of welding ground joint in the past is that the copper cash of ground wire cable bare front end part is directly overlapped or is stuck on the ground wire-fork, contact insecure, have the virtual connection situation, the amount of heat that produces when welding can make the meeting quick aging of copper cash joint, fracture.Broken and to have reconnected, affected construction schedule, also wasted time and materials simultaneously.
The utility model content
The purpose of this utility model is: a kind of electric welding ground connection clamp fastener is provided, realizes that welding quality is up to standard, solve the present situation of cable and ground wire-fork loose contact.
The technical solution adopted in the utility model is: electric welding ground connection clamp fastener, comprise earth plate, male connection, plug, steel pipe, screw, pad and copper conductor, it is characterized in that: an end of steel pipe is welded with plug, plug is circular, there is internal thread hole at the center of plug, internal thread hole at plug is fixed with a male connection, and male connection is cylindrical, and external screw thread is arranged; Outer face in male connection is welded with earth plate; Wall at steel pipe has two screws side by side, and the center line of two screws is vertical with the center line of steel pipe; Be fixed with respectively a screw in two screws, the pad of a cuboid is arranged in the steel pipe, the end of two screws is pressed in the top of pad; Penetrate copper conductor from the other end of steel pipe, the end of copper conductor is in the bottom of pad.Screw screw, pad compresses copper conductor, can not produce ground wire virtual connection phenomenon.
The beneficial effects of the utility model: the utility model electric welding ground connection clamp fastener, can compress copper conductor, can not produce ground wire virtual connection phenomenon, improve the electric welding construction quality.Avoid the workman frequently to adjust ground wire, improve efficiency of construction.
Description of drawings
Fig. 1 is the utility model electric welding ground connection clamp fastener structural profile schematic diagram.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1-earth plate, 2-male connection, 3-plug, 4-steel pipe, 5-screw, 6-pad, 7-copper conductor.
Embodiment
Embodiment 1: take an electric welding ground connection clamp fastener as example, the utility model is described in further detail.
Consult Fig. 1.The utility model electric welding ground connection clamp fastener comprises earth plate 1, male connection 2, plug 3, steel pipe 4, screw 5, pad 6 and copper conductor 7.
The length 200mm of steel pipe 4, internal diameter 50mm, an end of steel pipe 4 is welded with plug 3, plug 3 is circular, and there is the internal thread hole of a M20 at the center of plug 3, is fixed with the male connection 2 of a M20 at the internal thread hole of plug 3, male connection 2 is cylindrical, and external screw thread is arranged.Be welded with earth plate 1 in the outer face of male connection 2.Earth plate 1 is the steel plate of thickness 14mm.At the wall of steel pipe 4 screw of two M12 is side by side arranged, the center line of two screws is vertical with the center line of steel pipe 4.In two screws, be fixed with respectively a M12 screw 5, have the end of 6, two screws 5 of pad of a cuboid to be pressed in the top of pad 6 in the steel pipe 4.Penetrate the ground wire of copper conductor 7(electric welding machine from the other end of steel pipe 4), the end of copper conductor 7 is in the bottom of pad 6.Screw screw 5, pad 6 compresses copper conductor 7, can not produce ground wire virtual connection phenomenon.
