Flexible connectors, tools and robot systems for fastening bolts of live equipment in substations

Abstract

The invention puts forward a flexible connection head used for the bolt fastening operation of transformer substation electrically charged equipment, a bolt fastening tool of the transformer substation electrically charged equipment, and a robot system. The flexible connection head comprises an upper universal joint, a lower universal joint and a connecting rod, wherein the upper universal joint and the lower universal joint are connected through the connecting rod; the lower universal joint consists of a half convex universal joint and a half concave universal joint, wherein the half convex universal joint and the half concave universal joint are cooperatively connected; grooves are formed in the half convex universal joint and the half concave universal joint respectively; a magnetic regulation rod and an aligning spring are installed in the grooves in a clearance fit way; and the aligning spring is used for regulating the movement direction of the magnetic regulation rod to form a buckle in the position connected with a sleeve so as to realize fixed connection between the flexible connection head and the sleeve. The bolt fastening tool can realize a bolt assembling and disassembling operation in four quadrants, and the degree of freedom of the bolt fastening tool is increased. While the aligning spring, the connecting rod, the upper universal joint and the lower universal joint of the flexible connection head realize torque transmission, the rigidity of the flexible connection head is guaranteed.

Description

technical field [0001] The disclosure relates to the technical field of live working tools, in particular to a flexible connector, a tool and a robot system for fastening bolts of live equipment in substations. Background technique [0002] Replacing the insulator and disassembling the bus in the substation requires disassembling the fastening bolts. When the substation insulator is defective, it is necessary to disassemble the connecting bus to replace the insulator. At this stage, when the connection of the busbar is not tight, the line will generate heat. The disassembly and assembly of the busbar and the replacement of insulators in the substation mainly have the following disadvantages: [0003] (1) The disassembly and assembly of the busbar is mostly a power-off maintenance operation. Check the connection of the line and tighten it. In areas where high power continuity cannot arrange power-off maintenance, live maintenance operations cannot be performed. [0004] (2) ...

AI Technical Summary

Problems solved by technology

[0003] (1) The disassembly and assembly of the busbar is mostly a power outage maintenance operation. Check the connection of the line and tighten it. In areas where high power continuity cannot arrange power outage maintenance, live maintenance operations cannot be performed

[0004] (2) Replacing insulators and disassembling busbars are mostly manual operations. Manual operations face high-altitude operations, and there are safety hazards of falling from high altitudes
