The invention relates to a clamping apparatus of live line tools, which comprises a front clamping apparatus and a rear clamping apparatus; one end of the front clamping apparatus is provided with a first installation groove and a first curve part; one end of the rear clamping apparatus is provided with a second installation groove and a second curve part; the other end part of the rear clamp apparatus which is corresponding to the second installation groove is provided with a third installation groove, the end part of the rear clamping apparatus which is corresponding to the third installation groove is concavely equipped with a connecting chute, the connecting chute and the third installation groove are located at the two sides of the rear clamping apparatus respectively, and the connecting chute is communicated with the bottom of the third installation groove; and a hydraulic cylinder slide block is arranged in the connecting chute. In the invention, the front clamping apparatus is installed on a first hardware fittings set square; the rear clamping apparatus is installed on a second hardware fittings set square; and the rear clamping apparatus is connected with the front clamping apparatus through an insulation extraction stick, a hydraulic bearing tool expands the insulation gap between the insulation combination through the corresponding coordination of the front clamping apparatus, the rear clamping apparatus and the insulation extraction stick, and meanwhile the connection is safe and reliable, and fall off is not easy; and the clamping apparatus of the live line tools has a simple structure, is convenient to install and use, and is safe and reliable to use.
Description
technical field [0001] The invention relates to an electric power maintenance tool, in particular to a live insulator replacement tool, which belongs to the technical field of electric power tools. Background technique [0002] With the rapid development of my country's power grid construction, live work is becoming more and more important. In order to effectively increase the insulation distance when replacing the tension-resistant porcelain bottle string during live work, the overall structure of the 5-ton live-work universal hydraulic load-bearing tool must be installed at the end of the porcelain bottle string close to the cross arm. The connection is a spherical groove structure, which avoids stress concentration. At present, the clamps corresponding to the hydraulic load-bearing tools have insufficient insulation combination clearance distance, and the versatility with the line fittings and connecting plates is insufficient, and the original clamps are easy to fall o...
