Description

Technical Field

[0001] This utility model belongs to the field of conductive wires in steel pipe circumferential welded wires, and specifically relates to a conductive grounding wire device for large-diameter steel pipe circumferential welded wires. Background Technology

[0002] In existing methods for conducting electricity through grounding wires in circumferential welding of steel pipes, the clamp connecting one end of the grounding wire is typically attached to the steel pipe. Sparking will occur on the steel pipe, posing a risk of personal injury to welders, increasing the risk of accidents, reducing efficiency, and making welding inconvenient and difficult for welders. Utility Model Content

[0003] This utility model provides a grounding conductive device for circumferential welding of large-diameter steel pipes, which reduces occupational injuries to workers and increases safety.

[0004] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0005] A conductive device for grounding wire of large-diameter steel pipe with circumferential welded ground wire includes a conductive cylinder, a conductive copper plate movably sleeved on the conductive cylinder, and the outer wall of the conductive cylinder in contact with the inner wall of the conductive copper plate.

[0006] The conductive cylinder is connected to the bearing cylinder via a connecting flange. The bearing cylinder is mounted on the bearing seat, and the bearing seat is fixedly connected to the bearing seat base plate.

[0007] It also includes a faucet wire with conductive copper clips at both ends. One end of the conductive copper clip is used to hold the steel pipe, and the other end of the conductive copper clip holds the conductive cylinder.

[0008] Further technology of this utility model:

[0009] Preferably, the conductive copper plate is a U-shaped structure plate inverted on the conductive cylinder.

[0010] Preferably, the conductive copper plate is provided in multiple forms.

[0011] Preferably, a speed reducer drive device is placed on the bearing housing base plate, and the output shaft of the speed reducer drive device is connected to the bearing cylinder and drives the bearing cylinder to rotate.

[0012] Preferably, the conductive copper clip includes a main copper plate connected to the faucet wire, and the main copper plate is provided with a plurality of parallel vertical grooves, in which C-shaped copper clips are slidably connected.

[0013] Preferably, the main copper plate has a first fastening screw on its vertical groove that rests against the C-shaped copper clamp, and the C-shaped copper clamp has a second fastening screw that rests against the steel pipe and the conductive cylinder.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses a faucet wire with one end connected to a conductive copper clamp on a steel pipe and the other end connected to a conductive device. As the steel pipe is slowly rotated for welding, the conductive copper clamp on the pipe rotates accordingly. Through the faucet wire, the conductive device with the conductive copper clamp at the other end rotates slowly as well. The conductive device with the conductive copper plate attached will make good contact, and the conductive device with the conductive copper clamp will rotate and generate arcing. Throughout the process, arcing will not occur on the steel pipe, but only on the conductive device, successfully transferring the arcing phenomenon and ensuring a better working environment for the welder, thus providing better conductivity, protection, and safety.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] This embodiment provides a conductive device for grounding a large-diameter steel pipe with an 18mm circumferential weld, such as... Figure 1It includes a conductive cylinder 10, on which a conductive copper plate 11 is movably sleeved, and the outer wall of the conductive cylinder 10 is in contact with the inner wall of the conductive copper plate 11.

[0023] The conductive cylinder 10 is connected to the bearing cylinder 13 via the connecting flange 12. The bearing cylinder 13 is mounted on the bearing seat 14, and the bearing seat 14 is fixedly connected to the bearing seat base plate 15.

[0024] It also includes a faucet wire 17 with conductive copper clips 16 at both ends. The conductive copper clip 16 at one end is used to clamp the steel pipe 18, and the conductive copper clip 16 at the other end clamps the conductive cylinder 10.

[0025] Implementation method: One end of the faucet wire 17 is clamped to the large-diameter steel pipe 18 by a conductive copper clip 16; the other end of the conductive copper clip 16 is clamped to the conductive device; the steel pipe 18 rotates, and the conductive copper clip 16 clamped to the steel pipe 18 drives the faucet wire 17 to transmit force, which drives the conductive cylinder 10 to rotate, and the conductive cylinder 10 and the conductive copper plate 11 will rub against each other and generate sparks.

[0026] It should be noted that the rotation of the steel pipe 18 mentioned in this embodiment can be achieved by the roller frame 19. The roller frame 19 is provided with a concave steel pipe 18 placement area, and rollers on both sides support the steel pipe 18. The rollers can be driven by a motor.

[0027] Meanwhile, it should be noted that the conductive copper plate 11 in this embodiment can be designed to have a heavier self-weight or control the coefficient of friction to avoid rotating when it rubs against the conductive cylinder 10. Alternatively, rotation can be avoided through structural design. In this embodiment, the conductive copper plate 11 is a U-shaped structure plate that is upside down on the conductive cylinder 10, with the bottom of the conductive copper plate 11 in contact with the ground. The U-shaped structure plate upside down on the conductive cylinder 10 prevents it from rotating with the conductive cylinder 10.

[0028] Multiple conductive copper plates 11 are provided, enabling continuous friction with the conductive cylinder 10.

[0029] In this embodiment, to avoid insufficient force transmission from the faucet cable 17, a drive mechanism is provided on the conductive cylinder 10 to control its active rotation. However, it should be noted that the direction and speed of the conductive cylinder 10's active rotation are synchronized with the steel pipe 18. Specifically, as shown... Figure 2 :

[0030] A speed reducer drive device 20 is placed on the bearing base plate 15. The output shaft of the speed reducer drive device 20 is connected to the bearing cylinder 13 and drives the bearing cylinder 13 to rotate.

[0031] Furthermore, since the surface of the steel pipe 18 is arc-shaped, and the actual contact area between the conductive copper clip 16 and the steel pipe 18 varies depending on the diameter of the steel pipe 18, if the contact area is too small, the conductive copper clip 16 is likely to fall off.

[0032] In this embodiment, as follows: Figure 3 :

[0033] The conductive copper clip 16 includes a main copper plate 161 connected to the faucet wire 17. The main copper plate 161 is provided with three parallel vertical grooves 165, and a C-shaped copper clip is slidably connected in the vertical grooves 165.

[0034] The main copper plate 161 has a vertical groove 165 with a first fastening screw 163 pressing against the C-shaped copper clip, and the C-shaped copper clip has a second fastening screw 164 pressing against the steel pipe 18 and the conductive cylinder 10.

[0035] The conventional single conductive copper clip 16 is replaced with three C-shaped copper clips, and the three C-shaped copper clips can move up and down on the main copper plate 161 to maximize the fit with the arc-shaped steel pipe 18.

[0036] It should be noted that multiple first fastening screws 163 are provided. The first fastening screw 163 is selected according to the position of the C-type copper clip and is pressed against the C-type copper clip to fix the C-type copper clip.

[0037] In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
