Description

Technical Field

[0001] The invention relates to the technical field of power cables, and in particular to a power cable straightening and conveying device. Background Art

[0002] Electric power transmission refers to a method of transmitting electricity from one place to another by a power plant or power source. Due to the immature technology in the early days, electric power transmission mostly used direct current transmission, and later gradually evolved into alternating current transmission. AC transmission has many advantages, reducing the loss in power transmission and increasing the speed and transmission length. Cables are one of the indispensable components in the power transmission process, and cables need to be straightened for transmission during the power transmission process.

[0003] In the prior art, a cable straightening device is generally used to straighten a bent cable. The principle of cable straightening is to first clamp the two ends of the cable and then straighten it. For example, the patent publication number CN209786626U is a power cable straightening device. When in use, one end of the cable is placed into the cable clamping box through the connection hole, and the cable is placed between the clamping rings. The screw block is turned clockwise by the adjusting rod to move the screw downward, driving the gear rod to move downward. Through the joint setting of the connecting gear and the fan gear, the two connecting rods are swung inward, so that the three clamping rings gather together and one end of the cable is firmly clamped; similarly, the other end of the cable is placed in another cable clamping box and clamped, so that the two ends of the cable are firmly clamped and not easy to fall off. After the cable is clamped, the cylinder is started, and the cylinder drives the slider to slide to the left on the slide rail through the connecting block, thereby straightening the cable. Although it can straighten the cable, it is limited by the manufacturing length of the device and can only straighten shorter cables. Longer cables are longer than the sliding range of the slider and cannot be effectively straightened, so the scope of application is small.

[0004] In summary, the existing cable straightening device has the problem that it can only straighten cables of shorter lengths. Summary of the invention
