Overhead cable conveying device

Abstract

The invention discloses an overhead cable conveying device which comprises a tractor, protecting pulleys and a load-bearing rope. The tractor is connected with the protecting pulleys through the load-bearing rope. The tractor can provide power to allow the protecting pulleys to move on the rope. The operation status of the tractor can be controlled remotely. Each protecting pulley is provided with an upper pulley set and a lower pulley set and can be used normally or reversely. The overhead cable conveying device is simple in structure, low in manufacturing cost, convenient to operate and easy to popularize. When the overhead cable conveying device is applied to overhead common-tower double-circuit transmission line unilateral power failure cable replacement, construction safety is increased, working efficiency is increased, cost is lowered, and the requirements such as progress and environmental protection are satisfied.

Description

technical field [0001] The invention relates to the field of high-altitude optical cable erection equipment, in particular to a high-altitude replacement optical cable transportation device and method. Background technique [0002] With the intelligent development of the power grid, unattended communication projects implemented in 110kV and above voltage level substations need to erect ADSS optical cables for the communication of smart devices. Considering the construction design requirements and construction costs, the erection path is mostly selected in the original line conductor below. In the prior art, most of the wires are laid out in two ways: one is to use unmanned helicopters to release the wires, which is especially suitable for spreading across the woods; the other is to use manual routing, and the staff will take the wires along Lay out the wiring. However, most of the lines above 110kV are tower lines with a relatively long operating time. The trees below the ...

Problems solved by technology

Due to the large span of tension and traction, it usually needs to span hundreds of meters and several towers. The single-circuit power failure of the double-circuit operation line on the same tower may easily cause insufficient safety distance during the traction process and affect the safe operation of the line.

At the same time, in economically developed areas such as Shenzhen, labor wages are very high, environmental protection requirements are high, construction is difficult, and the procedures for continuously crossing power lines are complicated.

For this reason, the overhead line cannot be completely powered off, and it is necessary to quickly and accurately complete the replacement and inspection of optical cables

The existing installation method is far from meeting the need for quick replacement of optical cables
