Description

Technical Field

[0001] The present invention relates to the field of cable installation, in particular to a cable anti-falling device for an electric power tower. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of one or more conductors and an insulating protective layer covering the conductors. It is used to transmit electricity or information from one location to another. In transmission lines composed of cables, power towers are needed to erect the cables and separate them from the ground or other buildings. Publication (Announcement) No. CN119049812A discloses a cable anti-fall device for power towers. This technology discloses "a positioning seat mounted on the tower, with a fastening sleeve provided on the side of the positioning seat away from the tower. The fastening sleeve is connected to the end of the cable, and an insulator string is connected between the fastening sleeve and the positioning seat; a support ring assembly detachably mounted on the tower, corresponding to the exterior of the insulator string, comprising a first support ring, a second support ring, and a third support ring. The first support ring is fixedly connected to a support rod at its upper and lower ends, and anti-sway components are provided on both sides of the first and second support rings; and an adjustment assembly is provided on both sides of the third support ring, with the connection ends of the adjustment assembly connected to the fastening sleeve. This enables rapid adjustment of the support position of the detachably mounted insulators on the insulator string, significantly improving the efficiency of insulator replacement operations." However, the above technical solution relies too much on manual operation during the installation of the insulator string. Since the insulator itself has a large weight, it is very easy to fall during the installation and disassembly process due to the lack of anti-fall devices, causing safety accidents. In addition, the insulators are generally broken during the replacement process and cannot be recycled, resulting in a certain degree of waste.

[0003] In order to solve the above problems, a case is proposed in this application. Summary of the Invention
