Abstract
Description
Technical Field
[0001] The utility model relates to the field of line maintenance, and more specifically, to a device for removing fittings of overhead transmission lines. Background Art
[0002] In the power system, overhead transmission lines are important facilities for transmitting electricity, and fittings (such as suspension clamps, vibration dampers, etc.) are used to fix the conductors and protect them from wind vibration and galloping. However, during the maintenance, repair or replacement of transmission lines, these fittings need to be removed, and this process is currently mainly completed manually, which is not only inefficient but also has high safety risks.
[0003] The current methods for removing fittings usually include the following:
[0004] 1. Manual removal: Workers need to climb to the high-altitude working point and manually disassemble the fittings using tools such as wrenches and pliers. This method has a high labor intensity and there are safety hazards in high-altitude operations.
[0005] 2. Mechanical-assisted removal: Special robotic arms or aerial work platforms are used to assist workers in the operation. Although it reduces some labor intensity, manual operation is still required and the efficiency needs to be improved.
[0006] Although there are some devices that can move along the transmission line under control and cut the fittings, such devices are prone to shaking during cutting. Summary of the Utility Model

The upper shell 1 and the lower shell 2 can be aligned vertically and locked. A through channel runs through the middle of the upper shell 1 and the lower shell 2. Each of the front parts of the upper shell 1 and the lower shell 2 is provided with a semi-circular arc-shaped plate 4. The two arc-shaped plates 4 form a circular tube 5. The racks 6 located on the arc-shaped plates 4 are butted to form a toothed ring 13. The toothed ring 13 can rotate along the outer wall of the circular tube 5. A driving motor 7 is arranged at the front part of the upper shell 1. A gear 8 is arranged on the output shaft of the driving motor 7. The gear 8 meshes with the toothed ring 13.
