Problems solved by technology

[0002] During the installation of power cables leading down from the tower, due to the difference in the model of the tower and the diameter of the upper and lower sides of the tower, the electric construction personnel often encounter the problem that the diameter of the flat iron hoop fixed by the cable support cross arm is not suitable and cannot be installed normally; at the same time, Due to the lack of special grounding wires to support the cross-arm, the grounding wire can only be bundled and led down along the surface of the tower, which is not beautiful, but also affects the future work of the staff to climb the pole with iron shoes; the common cable support cross-arm adopts a U-shaped fixed size Screws fix the cable, the contact area is small, the pressure is concentrated, and the insulation layer of the cable is easily crushed, which accelerates the aging of the outer layer of the cable

Embodiment 1

[0019] A kind of pole tower down-leading cable supporting cross arm of this embodiment, refer to the attached figure 1 , 2 , 3. It includes a cross-arm main body 1 with an L-shaped structure, and the cross-arm main body 1 is provided with a tower clamp, a cable fixing device and a grounding wire fixing device.

[0020] The tower hoop is composed of two long bolts 2-1 and a flexible hoop 2-2 connecting the two long bolts. The flexible hoop 2-2 adopts a flexible steel belt structure. Bolt holes 2-3, that is, there are 3 bolt holes on the left and right respectively. The pole tower clamp is fixed on the main body 1 of the cross arm through the long bolt 2-1 and the different bolt holes 2-3 on the left and right. The long bolts are fixed on the bolts at different positions. The holes allow the clamp to adapt to towers of different diameters, which facilitates the connection and fixation of the main body of the cross arm. The cross arm main body 1 between the left and right bolt ...

Embodiment 2

[0022] A kind of pole tower down-leading cable supporting cross arm of this embodiment, refer to the attached Figure 4 , its structure is basically the same as that of Embodiment 1, the difference is that the flexible hoop 2-2 adopts a hinge structure, and an arc-shaped piece is arranged in the center of the hinge, and the arc-shaped notch corresponds to the main body 1 of the cross-arm, so that it is more convenient to move the cross-arm The card is fixed on the tower, and the card is more stable.

Embodiment 3

[0024] A kind of pole tower down-leading cable supporting cross arm of this embodiment, refer to the attached Figure 5 , its structure is basically the same as that of Embodiment 1, the difference is that the other end of the cross-arm main body 1 is respectively equipped with a circular arched cable fixing device and a grounding wire fixing device, and the inner side of the round arch top of the cable fixing device is provided with The cable protection layer 3-1 is equipped with an anti-wear layer 3-2 at the top of the corresponding circular arch on the cross-arm main body 1, thereby further protecting the cables in the maintenance process and prolonging their service life.

[0025] Wherein, the positions of the cable fixing device and the grounding wire fixing device are not limited to the only one, and the positions of the two devices can be interchanged without affecting the normal use of the tower's down-leading cable support cross-arm.

[0026] In the above embodiment, ...

Abstract

The invention relates to power equipment, in particular to a cross arm for supporting cables led down from a tower. The cross arm comprises a cross arm main body. A tower clamping hoop, a cable fixing device and a ground lead fixing device are arranged on the cross arm main body. The tower clamping hoop is composed of long bolts and a flexible hoop for connecting the long bolts and is fixed to the cross arm main body by matching the long bolts with corresponding bolt holes. The cross arm main body is provided with flat holes in bilateral symmetry, and a conical body is fixed in different positions of each flat hole through a bolt. The cable fixing device is provided with a cable protective layer and an anti-abrasion layer. According to the cross arm for supporting cables led down from the tower, the tower clamping hoop, the cable fixing device and the ground lead fixing device are arranged, the cross arm can be connected and fixed to different positions of the tower through the tower clamping hoop, a cable and a ground lead can be clamped and fixed through the cable fixing device and the ground lead fixing device separately, and therefore installation and fixing of the cable and the ground lead led from the tower can be realized.
