Guide pulley dedicated to unmanned aerial vehicle

Abstract

The invention discloses a guide pulley dedicated to an unmanned aerial vehicle. The guide pulley comprises a main body shell (1), wherein one end of the main body shell is connected with a side plate (2); the other end of the main body shell is connected with a connecting piece (3); the lower end of the connecting piece is connected with a pothook (4); a traction rope pulley (7) is mounted on the pothook; an electric cable pulley (6) is mounted between the main body shell and the side plate; a first spring (8) and a position-limiting rod are mounted in the main body shell; a lockpin (9) is arranged on one side of the first spring and is connected with a second spring (11); a pulley block is mounted in the main body shell; a steel wire rope (12) is arranged on the pulley block; one end of the steel wire rope is connected with the lockpin; and the other end of the steel wire rope is connected with the connecting piece. The guide pulley and a jettison system based on the guide pulley can precisely position through the unmanned aerial vehicle, and the guide pulley is directly adopted to transport a rope ladder or other tools to designated positions, so that the burden of a worker is greatly lowered and the risk of equipotential hot-line work is also reduced.

Description

technical field [0001] The invention relates to a guide pulley, in particular to a special guide pulley for unmanned aerial vehicles, which belongs to the technical field of unmanned aerial vehicles. Background technique [0002] The UAV-specific guide pulley is a device mounted on the eight-rotor UAV. Its main function is to hang the guide pulley on the ultra-high voltage and ultra-high voltage live wires by means of delivery and positioning, and assist live workers to enter the equipotential. [0003] In the prior art, live-work construction workers enter equipotential work by climbing transmission line poles and towers, and then move to the wire section where work is required. There are great disadvantages in such a working method, and there are many unstable factors. For example, the risk of climbing the tower, the technical difficulty and unsafety of moving from the tower to the equipotential, are extremely threatening to the personal safety of the staff. In addition...

AI Technical Summary

Problems solved by technology

[0004] In view of the existing problems in the above-mentioned prior art, the present invention provides a special guide pulley for UAV, which can solve the problem that the gap between pole and tower combination does not meet the requirements of live work, and personnel cannot enter the equipotential. Realize the ground climbing soft ladder to enter the equipotential, suitable for all transmission line towers, and does not require staff to climb the tower
