Description

Technical Field

[0001] This utility model relates to the field of steel structure construction, and in particular to a simple grounding device for the welding process of steel structure components. Background Technology

[0002] Prefabricated steel structure buildings are widely used in residential, public, and factory construction due to their excellent earthquake resistance, flexible space, and environmental friendliness. Prefabricated steel structure buildings are mainly composed of a large number of steel components of different sizes, connected by welding, bolts, and other methods. Welding is extensively used in the assembly and connection process; however, because the steel columns and beams are prefabricated steel components with rust-proof paint and smooth surfaces, the welding machine grounding wire cannot be properly connected to the steel columns and beams during welding, thus affecting welding quality and operational safety. Therefore, effectively solving the problem of connecting the welding machine grounding wire to the steel components during the welding process of prefabricated steel structure components has become a difficult challenge in the welding process.

[0003] Currently, the effective connection between the welding machine grounding wire and the steel component during the welding process of prefabricated steel structure components is usually achieved by welding conductor steel bars onto the steel component and connecting the welding machine grounding wire to the conductor steel bars to form a closed loop, thereby enabling the welding of the steel structure components. However, this connection method, which involves welding conductor steel bars onto the steel component, can easily damage the anti-rust coating on the surface of the steel component and cause damage to the steel component due to the welding current during the welding process, thus affecting the mechanical properties of the steel component and endangering structural safety.

[0004] Therefore, it is necessary to provide a simple grounding device for the welding process of steel structure components to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a simple grounding device for the welding process of steel structure components.

[0006] This utility model provides a simple grounding device for welding steel structure components, characterized in that it includes a rectangular iron plate, a spring, a U-shaped connector, a long screw, an irregularly shaped steel connecting plate, a small round-headed screw, a columnar connector, and screws;

[0007] A U-shaped connector is fixed to the upper surface of the rectangular iron plate. An irregularly shaped steel connecting plate is hinged to the inner side of the U-shaped connector via a long screw. One end of the irregularly shaped steel connecting plate is threaded to a small round-headed screw, and the other end of the irregularly shaped steel connecting plate is threaded to a screw. The end of the screw passes through the lower surface of the irregularly shaped steel connecting plate and is threaded to a columnar connector. The two ends of the spring are fixedly connected to the bottom of the irregularly shaped steel connecting plate and the center of the top of the rectangular iron plate, respectively.

[0008] A small, round-headed screw passes through the copper ring at the end of the welding machine's grounding wire. Tightening the screw with a screwdriver connects the welding machine's grounding wire to the shaped steel connecting plate. The columnar connector then contacts the surface of the steel structure component to be welded, forming a conductive circuit. Through the use of a spring and a long screw, the shaped steel connecting plate forms a lever structure along the long screw, ensuring tight contact between the columnar connector and the surface of the steel structure component.

[0009] Preferably, cylindrical magnets are symmetrically mounted on one end of the rectangular iron plate, and block magnets are mounted on the other end of the rectangular iron plate. This facilitates the adsorption and fixation of the rectangular iron plate onto the steel component.

[0010] Preferably, the bottom of the cylindrical magnet and the bottom of the block magnet are flush with the bottom of the rectangular iron plate, resulting in a good adsorption effect.

[0011] Preferably, the U-shaped connector is fixed to the rectangular iron plate by welding, resulting in a relatively stable connection.

[0012] Preferably, the bottom end of the columnar connector is conical, so that the columnar connector is in close contact with the surface of the steel structure component.

[0013] Compared with related technologies, the present invention provides the following beneficial effects:

[0014] With a compact structure and easy-to-operate, detachable design, it can solve the problem of effectively connecting the welding machine grounding wire to the steel components during the welding process of prefabricated steel structure components, reducing damage to the anti-rust coating on the surface of the steel components and the damage to the steel components caused by the welding current.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figs. 1-2 A simple grounding device for use in the welding process of steel structure components has the following specific structural features: The device is mainly composed of rectangular iron plate 1, spring 4, U-shaped connector 5, long screw 6, irregular steel connecting plate 7, round-headed small screw 8, columnar connector 9, and screw 10.

[0022] A U-shaped connector 5 is fixedly installed on the upper surface of the rectangular iron plate 1. The U-shaped connector 5 is fixed to the rectangular iron plate 1 by welding. This connection method ensures a stable connection between the two and prevents them from loosening during subsequent use. An irregularly shaped steel connecting plate 7 is hinged to the inner side of the U-shaped connector 5 by a long screw 6, which allows the irregularly shaped steel connecting plate 7 to rotate about the long screw 6 as an axis.

[0023] One end of the irregularly shaped steel connecting plate 7 is threaded with a small round-headed screw 8, and the other end is threaded with a screw 10. The end of the screw 10 passes through the lower surface of the irregularly shaped steel connecting plate 7 and is threaded with a columnar connector 9. The two ends of the spring 4 are fixedly connected to the bottom of the irregularly shaped steel connecting plate 7 and the top center of the rectangular iron plate 1, respectively. The spring 4 plays a key role in the subsequent use of the device.

[0024] In practical use, the copper ring at the end of the welding machine grounding wire is fitted onto the small round-headed screw 8, and then the small round-headed screw 8 is tightened with a screwdriver. In this way, the welding machine grounding wire can be reliably connected to the irregularly shaped steel connecting plate 7. The columnar connector 9 then contacts the surface of the steel structure component to be welded, thus forming a conductive circuit. Due to the presence of the spring 4 and the long screw 6, the irregularly shaped steel connecting plate 7 can form a lever structure along the long screw 6. When the columnar connector 9 contacts the surface of the steel structure component, the spring 4 applies a certain elastic force, allowing the irregularly shaped steel connecting plate 7 to automatically adjust its angle, thereby ensuring that the columnar connector 9 is in close contact with the surface of the steel structure component and ensuring good grounding effect.

[0025] To facilitate the adsorption and fixation of the rectangular iron plate 1 onto the steel component, cylindrical magnets 2 are symmetrically mounted on one end of the rectangular iron plate 1, and block magnets 3 are mounted on the other end. Furthermore, the bottoms of the cylindrical magnets 2 and the block magnets 3 are flush with the bottom of the rectangular iron plate 1. This design allows for full contact between the magnets and the surface of the steel component, resulting in better adsorption. In addition, to ensure a tighter contact between the columnar connector 9 and the surface of the steel structure component, the bottom end of the columnar connector 9 is designed in a conical shape. The conical bottom end better adapts to the unevenness of the steel structure component surface, further improving the tightness of the contact.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
