[0002] With the popularization of electric energy in our country, power cables are used in more and more places. Among them, power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead lines, internal power supply and Underwater power lines crossing rivers and seas, especially when erected underground or through utility poles, the cables need to be tensioned during the erection process so that the cables are in a tight state, but the general tensioning device for cable installation can only be The end of the cable is processed, and the position cannot be moved on the cable, which is very inconvenient

Embodiment 1
[0055] see Figure 1-Figure 10As shown, one of the purposes of this embodiment is to provide a tensioning device for power cable installation, including a tensioning device 100 and a support frame 200 arranged outside the tensioning device 100, and the tensioning device 100 at least includes:
[0056] Bottom plate 110, four corners of the top of the bottom plate 110 are provided with connecting screw rods 111;
[0057] Top plate 120, the top plate 120 is arranged on the top of the bottom plate 110, and the top of the top plate 120 is provided with a slot 123 corresponding to the position of the connecting screw 111 for plugging and mating with it. The inner wall of the slot 123 is ring-shaped and equipped with a plurality of elastic pressure plates 1231 , to limit the connecting screw 111 to prevent it from being skewed in the slot 123. In addition, the top of the connecting screw 111 is threaded with two connecting nuts 1111, and an extrusion is formed between the two connect...

The invention relates to the technical field of power cable installation, in particular to a tensioning device for power cable installation and an installation method of the tensioning device. The tensioning device comprises a tensioning device body and a supporting frame arranged outside the tensioning device body. According to the cable tensioning device, the arranged adjusting nut drives the moving rod to move longitudinally to achieve mutual staggering of the stretching type tensioning frames, so that the cable tensioning degree is improved by stretching the cable longitudinally under the condition that the transverse distance is not changed; and the tensioning effect is improved in a combined use mode while the longitudinal tensioning wheels are rotationally connected, so that the device is moved, the problem that the device is used at any position of the cable is solved, and abrasion to the cable can be reduced.
