Power transmission line strain clamp convenient for robot maintenance

Abstract

The invention relates to a power transmission line strain clamp convenient for robot maintenance, and belongs to the technical field of electric power fittings.The strain clamp comprises a drainage plate, a drainage wire clamp, a pressing rivet bolt, a flange nut and a marking gasket. A terminal plate of the drainage wire clamp is a curved-surface outer toothed plate and is provided with a through groove and outer teeth; the drainage plate is a curved-surface internal tooth plate, is provided with a bolt hole, an operation hole and internal teeth, is in close fit with the drainage wire clamp through meshing of the external teeth and the internal teeth, is in fastening connection through the pressing rivet bolt, the flange nut and the marking gasket, and is reliably prevented from loosening; and the lower end of the through groove is aligned with the operation hole, and the flange nut, the marking gasket, a manipulator and an operation tool can penetrate through the through groove so that assembly, disassembly and maintenance are safe, reliable and convenient, and ventilation is also facilitated. The marking gasket is provided with a color-changing rubber ring and a marking plate, the color of the color-changing rubber ring, the bending degree of the marking plate and contact traces can be obtained by shooting visible images, whether overheating occurs or not, the magnitude of fastening pre-tightening force and the installation and operation state are judged, and robot inspection and maintenance are facilitated.

Description

technical field [0001] The invention relates to a strain clamp, in particular to a strain clamp used for power transmission lines, and belongs to the technical field of electric power fittings. Background technique [0002] The strain clamp installed on the transmission line includes aluminum tubes, steel anchors, drain plates and drain clamps (also known as jumper drain terminal boards), which fix the wires on the strain insulator strings and play the role of anchoring and draining. Its drain plate and drain clamp must not only bear the tension of the jumper wire, but also need good electrical conductivity; during operation, overheating, deformation and cracking often occur, or even burn red, melt and break, which seriously threatens the safe operation of the transmission line. [0003] The drain plate and the drain clamp of the existing strain clamp are fastened and connected by bolts on a smooth plane, and the bolts need to maintain a fastening pre-tightening force.

Problems solved by technology

[0011] The bolted connection of the existing tension clamp is installed, disassembled and maintained manually through high-altitude operations. The intelligent inspection method of big data and wireless communication technology judges the degree of fastening, fastening state and operating state, which needs to be improved
