Abstract

The invention relates to a line tensioning device of a power overhead line. The line tensioning device comprises symmetric telescopic springs, a slide part, a first slide rail, a locking device, a power line mounting clamp, a limiting ring, a bidirectional winding motor and a second slide rail, wherein the telescopic springs are fixedly connected with the slide part, and the slide part is arranged on the first slide rail; the locking device is used for locking the slide part onto the first slide rail; the power line mounting clamp is used for bundling a plurality of power lines; the limiting ring is used for limiting the sliding of the power line mounting clamp; the bidirectional winding motor is arranged on the second slide rail, and is used for winding the power line between the symmetric telescopic springs. The line tensioning device of the power overhead line and a method have the advantages that by arranging the sliding telescopic springs, the verticality of the power overhead line is conveniently adjusted; by arranging the bidirectional winding motor, tensioning the line at low altitude, and then simply adjusting the height, the line tensioning is simplified, and the safety in working is improved.

Description

technical field [0001] The invention relates to auxiliary equipment for electric power construction, in particular to a wire tightening device for electric overhead lines. Background technique [0002] With the rapid growth of the country's economy, people's demand for electricity is also increasing. What follows is the construction of corresponding power equipment. Among them, the most important part of power equipment is the construction of power lines. In order to reduce the danger caused by power lines to residents and improve space utilization, most of my country currently uses power overhead lines to lay power lines. [0003] However, for the erection of power overhead lines in the prior art, relevant workers are usually required to carry out high-altitude operations on the power tower. Due to the weight of the power line and the large force required for the tensioning of the power overhead line, the staff is in an unsafe state when performing the tensioning operatio...
