[0002] In the production of concrete electric pole, it is necessary to weld the reinforcement cage first. The current welding of the reinforcement cage is carried out through the seam welder equipment. In the welding, the main reinforcement is supported outside the electrode disc, the equipment pulls out the main reinforcement to one side, and then the resistance welding is used to wrap and weld the ring reinforcement on the outer wall of the main reinforcement. In this process, the main reinforcement directly rubs the electrode disc, and the electrode disc is easily abraded. After serious abrasion, the electrode disc needs to be replaced as a whole, which has high use cost. In order to solve this problem, the technical personnel of the company designs a concrete electric pole reinforcement cage seam welder electrode disc.

However, the main reinforcement still directly rubs the copper sleeve, the copper sleeve is relatively thin, the durability is poor, and the service life is short. CONTENT OF THE UTILITY MODEL

By providing a plurality of notches 11 on the outer circumferential wall of the disc body 10, each notch 11 is installed with a support shaft 30, and the conductive roller 20 is rotatably installed on the support shaft 30. In use, the main reinforcement 50 is supported on the conductive roller 20, the conductive roller 20 rolls with the main reinforcement 50, reducing the friction between the electrode disc and the main reinforcement 50, and improving the service life of the electrode disc.

[0032] In this embodiment, see Figure 3 The disc body 10 is provided with notches 12 on both sides of the notch 11, and the both ends of the support shaft 30 are installed in the notches 12 on both sides through the screws 31.

[0033] Further, in order to improve the flexibility of the conductive roller 20, the bearing mounting grooves 21 are respectively arranged at both ends of the center hole of the conductive roller 20, the bearings 22 are installed in the bearing mounting grooves 21, and the support shaft 30 passes through the bearings 22.

[0034] Further, a spacer ring 23 is mounted on the support shaft 30 between the notch 11 and the bearing 22. The position of the conductive roller 20 is limited by the spacer ring 23, preventing the conductive roller 20 from moving on the support shaft 30.

[0035] In order to position the main reinforcement 50, a ring groove 24 is provided on the conductive roller 20.

[0036] In the embodiment, the conductive roller 20 and the support shaft 30 are made of copper, and the bearing 22 is a self-lubricating bearing. The main body of the self-lubricating bearing is a copper ring, which is filled with graphite. The self-lubricating bearing has good lubricity and conductivity.

[0037] In the embodiment, a key groove 14 is provided on the inner wall of the central hole of the disc body 10. During installation, the key groove 14 is matched with the central shaft of the seam welding equipment through a flat key, preventing the disc body 10 from rotating during production, which causes the conductive roller 20 to be misaligned with the main reinforcement 50.

[0038] Embodiment 2:

[0039] Based on the embodiment 1, referring to Figure 3 , a blind hole 13 is further provided at the bottom of the notch 11, and a carbon brush unit 40 is installed in the blind hole 13. The carbon brush unit 40 elastically abuts against the conductive roller 20. By installing the carbon brush unit 40, the conductivity of the disc body 10 and the conductive roller 20 is improved.

[0040] After adopting this structure, the conductive roller 20 is made of copper, and the support shaft 30 can be made of steel, and the bearing 22 can be a ball bearing.

In the case of ensuring the support height of the main reinforcement 50, the service life of the conductive roller 20 is further prolonged. When the conductive roller 20 is further worn out and cannot be used, the conductive roller 20 is replaced separately.

[0046] In use, the electrode disc of the application is installed on the center shaft of the roll welding equipment, and the eight conductive rollers 20 respectively support the eight main steel bars 50. When the main steel bars 50 are pulled outward, the conductive rollers 20 roll along with the main steel bars 50, reducing the friction between the electrode disc and the main steel bars 50, thereby improving the service life of the electrode disc.

[0047] After the conductive roller 20 is worn, the gasket 25 is installed between the support shaft 30 and the notch 12. The height of the conductive roller 20 is raised through the gasket 25, the support height of the main steel bar 50 is ensured, and the service life of the conductive roller 20 is further prolonged.
