Problems solved by technology

[0002] At present, when distributing overhead lines in the network, the tower and the overhead wire are usually connected together with a porcelain cross-arm, that is, the overhead wire is fixed on one end of the porcelain cross-arm by tying the wire, and the other end is fixed on the pole tower with a fastener. The installation method usually requires manual close-range operation and judges whether it is fixed firmly according to experience. In addition, when replacing the overhead wire, it is necessary to use the insulating operating rod to remove the binding wire and replace the wire, and then use the insulating operating rod to secure the binding wire in the form of a cross Winding and fixing the wires on the porcelain cross-arm in an unreasonable manner not only leads to low efficiency of disassembly and assembly, but also makes it difficult to ensure the stability of the installation

Embodiment 1

[0032] Such as figure 1 As shown, this embodiment provides a porcelain cross-arm, which includes a porcelain cross-arm body 1, a wire fixing assembly and a pole-tower connecting assembly respectively arranged at both ends of the porcelain cross-arm body 1, and the wire fixing assembly includes a buckle with an opening 22 and a movable part 23, the movable part 23 is swingably arranged at the opening to avoid the wire from entering the buckle 22 from the opening or blocking the opening so that the wire is fixed in the buckle 22; the tower connection assembly includes an adjustable The inner diameter of the lock ring 31, the lock ring 31 can be sleeved outside the tower.

[0033] During installation, turn the movable part 23 to make the wire pass through the opening and fit in the buckle 22 and turn the movable part 23 in the opposite direction to block the opening to fix the wire, and then set it on the pole tower through the lock ring 31 and adjust its inner diameter Prevent ...

Embodiment 2

[0045] This embodiment provides a porcelain cross-arm, which further improves the stability of the connection between the porcelain cross-arm and the wire and the tower on the basis of the first embodiment.

[0046] Specifically, a first anti-slip layer is laid on the inner wall of the buckle 22 to prevent the buckle 22 from sliding along the axial direction of the wire, thereby affecting the stability of the connection between the porcelain cross arm and the tower. Similarly, the inner wall of the movable part 23 may also be laid with a first anti-slip layer, which is not specifically limited in this embodiment.

[0047] Further, the inner wall of the lock ring 31 is laid with a second anti-slip layer to prevent the lock ring 31 from sliding along the axial line of the tower, thereby affecting the stability of the connection between the porcelain cross arm and the wire.

[0048] Exemplarily, both the first anti-slip layer and the second anti-slip layer are made of rubber mate...

Abstract

The invention relates to the technical field of power distribution network installation tools and particularly relates to a porcelain cross arm. The porcelain cross arm comprises a porcelain cross arm body, a wire fixing assembly and a tower connecting assembly, wherein the wire fixing assembly and the tower connecting assembly are arranged at two ends of the porcelain cross arm body respectively, and the wire fixing assembly comprises a retaining ring with an opening and a movable part; the movable part is arranged at the opening in a swinging manner so as to avoid a wire and enable the wire to enter the retaining ring from the opening or block the opening and enable the wire to be fixed in the retaining ring; the tower connecting assembly comprises a locking ring with the adjustable inner diameter, and the locking ring can be arranged outside the pole tower in a sleeving mode. The device is simple in structure and convenient to use, and mounting stability is guaranteed while dismounting and mounting efficiency is improved.
