Description

Technical Field

[0001] The utility model relates to the technical field of suspension equipment, in particular to an optical cable hardware suspension device for an ultra-high voltage power tower. Background Art

[0002] Ultra-high voltage transmission refers to 1000 kV AC and ±800 kV DC transmission projects and technologies. Transmission cables are erected on iron towers. Between the transmission cables and the towers, there are multiple sets of optical cable hardware for fixing, protecting and connecting the optical cables.

[0003] When suspending and installing the optical cable fittings of the ultra-high voltage power tower, a suspension device is usually required to suspend the fittings on the tower to facilitate the suspension and fixation by power workers. A winch and a pulley group are usually used in collaboration. The fittings are hung on the hook at the end of the winch cable. As the winch reels the cable, the fittings are suspended and raised. There are some functional deficiencies in actual use and there is room for improvement. For example, when suspending and raising the fittings, taking the wire-laying pulley as an example, the top of the wire-laying pulley will be equipped with a long string of insulators. During the suspension process, the insulator string and the pulley at the bottom will swing left and right due to the influence of high-altitude airflow, which can easily cause damage to the insulators. In addition, a traction rope needs to be tied to the pulley for bottom traction during the suspension process. When the fittings reach the designated position, the staff needs to manually untie the traction rope. The traction rope is located at a low position, which is inconvenient to operate and more dangerous. It does not have the function of protecting the fittings while facilitating traction.

The C-shaped clamp 18 forms a ring buckle, which can buckle the steel structure on the iron tower. The multiple groups of positioning holes 17 make its installation more flexible and convenient for fixing the positions of the first pulley 15 and the second pulley 16.

[0033] Embodiment 3: A first concave fixing frame 23 is welded to the right side of the top of the bottom fixing frame 1. The top of the first concave fixing frame 23 is fixedly connected to the second concave fixing frame 24.
