Description

Insulator wire fixing device for distribution line

technical field

The invention belongs to the technical field of wire fixing devices for distribution lines, in particular to a device for fixing insulators and wires in distribution lines and distribution transformer benches.

Background technique

The overhead transmission wires in distribution lines and distribution transformer benches are fixed by insulators. Especially in the wild, the wires of overhead transmission lines are easily affected by weather such as lightning, strong wind, rain and fog, and it is very important to fix the wires firmly. If the connection between the wire and the insulator is not tight enough, the wire is easily affected by the wind and gallops, which affects the service life of the insulator and the safety of power transmission. In the existing transmission lines, most of the fixing of the wires and the insulators adopts the binding type, and the wires are fixed on the insulators with the binding wires, but the binding wires will naturally loosen. Some fixing cards are also used to fix the wires, but the existing commonly used fixing cards are integrated with the card holder and the card holder, which has poor applicability. For different occasions, it is necessary to make various types of fixing cards, which is inconvenient to use.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a fixing device for connecting wires of transmission lines and insulators with wide applicability and convenient use.

In order to solve the above-mentioned technical problems, the present invention includes a clamp base, a support arm and a clamp head, and a fixing device is arranged on the clamp base. There is a fixing device for fixing and connecting between them, and both ends of each seat frame are provided with support arms that are movably connected with them.

The middle part of the seat frame of the clamping seat is provided with a curved curved part, the curved parts of the two seat frames form a clamping opening, the seat frame is provided with a screw hole, the fixing device is a screw, and the screw is inserted into the screw hole.

The lower end of the support arm is provided with a fork head, the fork head is provided with a fixing hole, the fork head is inserted into the seat frame and fixed on the seat frame by screws.

After adopting the above structure, because the present invention has two seat frames arranged in parallel, both ends of each seat frame are provided with support arms that are flexibly connected with them, the support arms are provided with chucks, and a fixing device is provided between the seat frames . The invention is mainly used for fixing insulators and wires in distribution lines and distribution transformer benches. When using, the base frame is first connected to the rod-type insulator end shank through the fixing device, and then the clamp is clamped on the wire. , and then tighten the fixing device. The support arm and the seat frame are flexibly connected. For different occasions, only the support arm can be replaced; at the same time, the angle between the support arm and the seat frame can also be fine-tuned, which is widely applicable and easy to use.

Description of drawings

Below in conjunction with accompanying drawing and embodiment, the present invention is further described:

Fig. 1 is the overall schematic diagram of the present invention;

Fig. 2 is the split schematic diagram of support arm and seat frame of the present invention;

specific implementation

Referring to FIG. 1 and FIG. 2 , the insulator wire fixing device of a distribution line includes a clamp base 1 , a support arm 2 and a clamp head 3 . The clamp base 1 includes two base frames arranged in parallel. The middle part of the base frame is provided with a curved curved part. The sides are respectively provided with screw holes 12 . A fixing device 13 for fixing is provided between the two brackets. In this embodiment, the fixing device 13 is a fixing screw, the fixing screw is inserted into the screw hole 12, and the fixing screw is provided with a nut. Both ends of each seat frame are provided with a support arm 2 movably connected to it, the lower end of the support arm 2 is provided with a "U"-shaped fork 21, the fork head 21 is provided with a fixing hole 22, and the fork head 21 is inserted into the seat frame. Blind holes are arranged on the seat frame, and the blind holes are arranged on the opposite outer sides of the two seat frames. Two blind holes can be set at both ends of each seat frame, so that the angle between the support arm and the seat frame can be fine-tuned. The head 21 is connected and fixed with the seat frame through screws 23, and the inner ends of the screws 23 are fixedly pressed in the blind holes. The upper end of each arm 2 is provided with a collet 3, the inner surface of the collet 3 is in the shape of an arc surface, and the arc surfaces of the collet 3 on the arms 2 at the same end of the two brackets are arranged opposite to each other.

Referring to Figure 3, when the present invention is in use, two brackets are clamped on the column head of the insulator 5, and a support arm 2 with a suitable height is selected. The fork head 21 is connected with the seat frame, and then the screws 23 and the fixing device 13 are tightened in sequence.
