Embodiment 1
[0026] Such as Figure 1-Figure 6 As shown in the figure, a cable routing device for high-altitude operation of transmission lines includes a housing, a locking mechanism, and a braking system.
[0027] The casing includes a main casing 1 , a secondary casing 2 and a rotating casing 3 . The shell is left-right symmetrical as a whole, nearly dumbbell-shaped. The upper part of the main housing 1 forms an arc-shaped wire groove 11, and the transmission line 14 contacts the upper surface of the inner side of the main housing 1 through the circular wire groove 11 during operation; the rotating housing 3 is symmetrical to the upper part of the main housing 1, The lower part of the main housing 1 and the secondary housing 2 jointly form a cuboid cavity 12 protruding from the upper part of the main housing 1 and the rotating housing 3 . The secondary housing 2 is fixedly connected to the lower part of the main housing 1 by screws, and the rotating housing 3 is rotationally connected...

The invention discloses a power transmission line high-altitude work wiring device, and belongs to the field of an electric power system wiring device. The brake system of the wiring device comprises a brake handle, balance blocks, self-locking mechanisms and multiple springs. The springs are fixed on the bottom surface of the two end parts of a cuboid empty slot. One self-locking mechanism is fixedly connected on the top part of each of the springs of the two end parts of the cuboid empty slot. One balance block is arranged at the internal side of each self-locking mechanism. Each balance block is rotatably arranged in the cuboid empty slot through a balance block rotating shaft. The balance block rotating shaft is arranged to be perpendicular to the central axis of a circular arc lead slot. The brake handle is installed in the cuboid empty slot in an upward and downward slidable way and positioned between the two balance block. One end of each balance block is lapped on the shoulder part of the self-locking mechanism and the other end is lapped on the shoulder part of the brake handle. The top part of the self-locking mechanisms and the top part of the brake handle are provided with a wear-resistant material layer. The power transmission line high-altitude work wiring device has great safety without the phenomenon of stagnation.
Description
technical field [0001] The invention relates to the field of wire routing devices for electric power systems, in particular to a wire routing device for high-altitude operation of power transmission lines. Background technique [0002] The safe and stable operation of high-voltage transmission lines directly affects the reliability of the power system. However, due to the large and complex power grid lines in my country, the harsh environmental conditions in some areas, and factors such as long-term exposure to the sun and natural disasters, frequent faults occur in power grid lines. Therefore, it is necessary to Conduct regular maintenance on the transmission line, understand the operating status of the line, and at the same time repair the faulty line in time, discover and eliminate hidden dangers, prevent accidents, and ensure power supply safety. [0003] At present, the maintenance of high-altitude transmission lines mainly adopts manual methods, supplemented by wiring d...
