Description

A wire lifting device

technical field

The utility model belongs to the technical field of line erection in electric power systems, in particular to a wire lifting device.

Background technique

With the rapid development of China's economy, the power supply is relatively tight. In order to meet the needs of national economic and social development, the country needs to speed up the process of power system construction. During the line erection process of the power system, especially when erecting over a long distance, it is often necessary to lift and fix the middle part of the cable to avoid damage, safety and aesthetics of the cable caused by excessive span. However, the existing cables are usually lifted and fixed by a simple bundling method. This method has problems such as complicated bundling process, low work efficiency, poor firmness, and easy to fall off, and there are certain safety hazards in the lifting process. In addition, in the maintenance of power lines, especially in the field of transmission towers or poles, during construction and maintenance, the wire should be lifted to the top of the transmission tower or pole. At this time, the widely used method is to use the hook as a wire lifting tool. On the one hand, the suspension hook will wear the wires in different degrees when it is promoted, and on the other hand it is very easy to cause the wires to come off, which makes it very inconvenient for the wires to be promoted, and also makes the erection or maintenance process of the whole line time-consuming and laborious.

Utility model content

In view of this, the purpose of the utility model is to provide a wire lifting device which is not only convenient for lifting, but also can prevent wire wear.

A wire lifting device, including a base, a lifting frame and a wire fixing clamp, the base is a groove with an opening downward, a fastening screw is set on the side wall of the base, a push plate is set on the top of the screw, and a push plate is set on the base. At the middle position of the lifting frame, a wire lifting device is arranged at both ends of the lifting frame, and the wire lifting device is composed of a winding shaft, and a wire fixing clip is arranged at the lower end of the wire lifting device.

The wire fixing clip is composed of a clip and a wire fixing device. The wire fixing device is two arc-shaped sliders, and the sliders are respectively arranged in the middle of the two jaws of the clip through hard springs.

A threaded hole is provided at the ends of the jaws, and a screw rod is set through the threaded hole.

A handle is provided on the side wall of the wire lifting device.

The beneficial effect of the utility model is that the utility model can be conveniently clamped on the lifting frame through the downward opening groove arranged in the middle of the lifting frame and the fastening nut with the push plate arranged on the side wall of the groove. On crossarms of different sizes. The wire fixing clip is composed of a clip and a wire fixing device. When the structure is lifted, it is only necessary to move the handle of the clip to open the two jaws, and the sliders arranged in the middle of the two jaws are also separated from each other. The wire to be lifted is placed between the two arc-shaped sliders, and the handle of the clip is released. At this time, the wire to be lifted is fixed under the joint action of the elastic force of the hard spring and the clip. At the same time, because the two sliders pass through the spring The structure connected with the clamp can effectively reduce the wear and damage of the clamp to the wire body. Finally, after the wire is lifted to the top, the wire can be removed by moving the handle of the clip, and during the lifting process of the wire, the locking and closing device arranged between the two jaws can further prevent the wire from slipping. In a word, the utility model can lift the wire to the top of the pole tower quickly and without wear by one person, which greatly improves the efficiency of stringing and is convenient for popularization and use.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model wire hoisting device;

Fig. 2 is a structural schematic diagram of the jaw of the utility model fixing clip.

Detailed ways

As shown in Figure 1 and Figure 2: a wire lifting device, including a base 1, a lifting frame 4 and a wire fixing clip, the base 1 is a groove with an opening downward, and the side wall of the base 1 is provided with a fastening screw 3. A push plate 2 is arranged on the top of the screw rod 3, and the utility model can be conveniently fixed on cross arms of different sizes by adjusting the push plate 2. The base 1 is arranged at the middle position of the lifting frame 4, a wire lifting device is respectively arranged at the bottom ends of both sides of the lifting frame 4, and a wire fixing clamp is arranged at the lower end of the wire lifting device. Wherein, the wire lifting device is composed of a winding shaft 5 and a handle 6 connected to it, and the wire can be quickly lifted by turning the handle 6; the wire fixing clip is composed of a clip 7 and a wire fixing device, and the wire fixing device is Two arc-shaped sliders 9 are respectively arranged in the middle of the two jaws of the clip through hard springs 8 . In addition, a threaded hole is provided at the ends of the jaws, and a screw 10 is inserted through the threaded hole. This structure can further prevent the wire from slipping during the lifting process and improve the safety during operation.

When the utility model is in use, the base 1 is first placed on the cross arm, the push plate 2 is pressed against the side wall of the cross arm and the screw rod 3 is tightened to fix the base; then the handle 6 is turned to lower the clamp to the ground. The staff located below move the handle of the clip 7 to open the two jaws, and the sliders 9 arranged in the middle of the two jaws are also separated from each other, and the wires to be lifted are placed between the two arc-shaped sliders 9, Loosen the handle of the clip 7, at this time, the wire to be lifted is fixed under the joint action of the elastic force of the hard spring 8 and the clip 7, and at the same time, because the two sliders 9 are connected to the jaw through the spring 8, This structure can effectively reduce the wear and damage of the clamp to the wire body; finally, the upper staff turns the handle 6 to lift the wire to the top, and then moves the handle of the clamp 7 to remove the wire. In addition, during the lifting process of the wire, the screw rod 10 inserted between the two jaws can lock and close the jaws, which can further prevent the wire from slipping.
