Tackle suitable for continuously unfolding guide rope of unmanned aerial vehicle and application method thereof

Abstract

The invention discloses a tackle suitable for continuously unfolding a guide rope of an unmanned aerial vehicle and an application method of the tackle. The tackle comprises a main supporting frame and multi-groove pulleys installed on the main supporting frame. Two multi-groove pulleys are installed on the supporting frame side by side, and the upper end of the main supporting frame is provided with a rope guiding plate capable of guiding a guiding rope into the main supporting frame and a blocking rod for blocking the guiding rope entering the supporting frame from running out. The tackle only needs to be hoisted once. The weight of the tackle is increased. Windage yaw in a wire laying process can be reduced. The safety of three-span construction is improved. The rope guiding plate cooperates with the unmanned aerial vehicle to guide the guiding rope into the tackle, and then the blocking rod is closed to prevent the wire entering the tackle from running out due to external force. The guiding rope can be guided into the middle wire groove of the multi-groove pulleys through a hinge door, so that the unmanned aerial vehicle flies along the middle wire groove. When the guiding ropeis pulled, endurance relay of two unmanned aerial vehicles can be adopted until gear-by-gear continuous unfolding and unfolding of the guiding rope are achieved. Only a plurality of rope heads need to be arranged on the front section of the guiding rope to be connected with the unmanned aerial vehicles, and the unfolding and unfolding process is safe and efficient.

Description

technical field [0001] The invention belongs to the field of power transmission line erection, in particular to a tackle suitable for unmanned aerial vehicles to continuously deploy guide ropes and an application method thereof. Background technique [0002] Split wire is a wire erection method adopted by EHV and UHV transmission lines to suppress corona discharge points and reduce line reactance. [0003] Classified wires are commonly divided into 4 strands, 6 strands, and 8 strands. Splitting the wire can change the distribution of the magnetic field around the wire, thereby equivalently increasing the radius of the wire and reducing the reactance of the wire; at the same time, it also changes the distribution of the electric field around the wire, increasing the susceptance of the wire accordingly. Compared with conventional wires, split wires have obvious advantages. Applying split wires to low-voltage distribution networks can reduce voltage drop and effectively improv...

Problems solved by technology

[0004] Pulleys are generally used for the erection of split conductors. For example, UHV DC transmission lines and UHV AC transmission lines often use eight-split conductors, and the current pulleys have five-wheel pay-off tackles, so two five-wheel pulleys are required for the deployment of eight-split conductors. car, and the two five-wheel pay-off blocks need to be hoisted separately, resulting in long hoisting time and low efficiency

In addition, the weight of a single five-wheel block is relatively light, which may easily cause wind deflection when the conductor is deployed, so that the safety of the "three-span" construction cannot be guaranteed

[0005] In addition, at present, the guide rope is generally deployed to the top of the tower by the UAV, and the guide rope is manually inserted into the pulley to carry out the deployment of the guide rope. The labor intensity is high and continuous deployment cannot be achieved, and the efficiency is low.
