System for disconnecting or connecting drainage wire of distribution network in alive state and method thereof for disconnecting or connecting drainage wire

Abstract

The invention discloses a system for disconnecting or connecting a drainage wire of a distribution network in an alive state and a method thereof for disconnecting or connecting the drainage wire. Thesystem includes a crawler overhead work vehicle and a working robot platform installed at the tail end of the lifting arm of the crawler overhead work vehicle. The working robot platform includes a control box, mechanical arms, and working tools connected to the tail ends of the mechanical arms. The first and second mechanical arms are both multi-joint multi-degree-of-freedom arms and are symmetrically mounted on both sides of the control box. Each working tool includes a clamping tool, a wire stripping tool and a wire clamp installation tool. The clamping tool is connected to the tail end ofthe first mechanical arm and is mainly configured to clamp an insulated wire and a lead. The wire stripping tool and the wire clamp installation tool are fixed to the top surface of the control box.The second mechanical arm connects the wire stripping tool and the wire clamp installation tool for corresponding operations through an electric rotary joint at its tail end as required. The system can keep workers away from an overhead high-voltage working environment, improves the safety of work and reduces the labor intensity of the workers.

Description

technical field [0001] The invention belongs to the field of live distribution network work, and specifically relates to a system for disconnecting and connecting drain wires of a distribution network and a method for disconnecting and connecting drain wires thereof. Background technique [0002] With the rapid development of social economy, people's requirements for continuous and stable power supply in production and life are getting higher and higher. The distribution network is at the end of the power system and is the key link to ensure the continuous supply of power. Its reliability occupies a very important position in the entire power supply system. At present, the live maintenance of the traditional distribution network is mainly carried out manually. Most of the workers wear insulating clothes and stand in the high-altitude insulating bucket to carry out the work of disconnection and drainage of live wires. line work. However, the distribution network lines are u...

Problems solved by technology

[0004] However, looking at the existing live working robot systems at home and abroad, the wheeled vehicle-mounted method is generally adopted, that is, the insulated mobile platform adopts a wheeled aerial work vehicle, and the operating robot is installed at the end of the telescopic arm of the wheeled aerial work vehicle. Vehicle-mounted mobility is not suitable for complex terrain environments

The working robot is installed on the insulating bucket truck, which makes it bulky, and the change of its working position is realized by the telescopic arm of the working vehicle, which is not suitable for narrow working space and complex working objects

And some working robots work through the mechanical arm without a dedicated working end

Even though some ends connected by the mechanical arm are used for stripping and clamp installation operations, the structure of the end is complex and the performance is not high, which makes it prone to failure during the operation
