Double-pulley tackle based on unmanned aerial vehicle

Abstract

The invention provides a double-pulley tackle based on an unmanned aerial vehicle. The double-pulley tackle comprises a tackle body provided with an opening, an advancing pulley and a lifting pulley,wherein the advancing pulley is located in the tackle body and the lifting pulley is located at the lower end of the tackle body; a baffle is arranged on the tackle body, and the baffle is rotationally connected with the tackle body so as to open or close the opening; the double-pulley tackle further comprises a pull rope and a sliding rod, wherein the sliding rod is located above the tackle bodyand can move up and down; one end of the pull rope is arranged on the baffle, and the other end is arranged at the lower end of the sliding rod; a pull ring convenient for clamping the unmanned aerialvehicle is arranged at the upper end of the sliding rod; the unmanned aerial vehicle clamps the pull ring to drive the sliding rod to move upwards, and the sliding rod moves upwards to drive the pullrope to pull the baffle so as to open the opening, so that a wire enters the tackle body from the opening and is matched with the advancing pulley, and only the unmanned aerial vehicle needs to be operated to drive the double-pulley tackle to move to the guide wire, without using an operation rod to pull the pull rope; and therefore the operation is simple and convenient, and the use of the double-pulley tackle is more convenient.

Description

technical field [0001] The invention relates to the technical field of double-pulley tackle, in particular to a drone-based double-pulley tackle. Background technique [0002] When defects such as loose strands, loose strands, and broken strands occur in the wire part of the high-voltage transmission line or when the defect occurs in the spacer part, the operator often needs to carry out live work maintenance, and the insulating ladder is transported to the defect by the lifting pulley on the double pulley block. The operator climbs the soft ladder to reach the defect, and carries out live maintenance work. How to hang the traveling pulley on the wire is a difficult part of the specific operation. At present, the operating rod is usually used to hook the rope on the double pulley block. Pull the baffle plate on the pulley to open the opening, and hang the traveling pulley on the wire through the operating rod. Since the rope on the double pulley block is easy to swing left ...

AI Technical Summary

Problems solved by technology

Since the rope on the double pulley block is easy to swing from side to side, it is difficult for the operating rod to hook the rope, which makes the operation inconvenient, and this method is only suitable for straight towers and low-voltage tension towers. Higher voltage grades (220kV and above) The tension tower insulator string is longer, and the suspension of the operating rod is more difficult
