Traveling device that can climb over 220kv horizontal double-split conductor spacer bars

Abstract

The invention discloses a walk device capable of crossing spacer rods on 220 kV horizontal double split conductors. The walk device comprises two sets of walk wheel assemblies. Each walk wheel assembly comprises a walk front wheel, a walk back wheel and a crossing wheel which can be changeable in positions mutually and are uniformly distributed on the same circumference surface, wherein the walk front wheel and the walk back wheel walk on a wire, and the crossing wheel is arranged above the wire; and when the walk front wheel meets a spacer rod, the crossing wheel crosses to the wire ahead of the spacer rod, and the walk back wheel is turned to the place above the wire to avoid the spacer rod. When not being hindered by the spacer rod, the walk device can walk on the wires quickly and stably through the walk wheels; when walking to the damaged spacer rod, the walk device can replace the spacer rod quickly; and when walking to the undamaged spacer rod, the walk device can walk over the spacer rod automatically and walks on.

Description

technical field [0001] The invention relates to a traveling device on a high-voltage transmission line, in particular to a traveling device capable of climbing over 220kV horizontal double-split wire spacer bars. Background technique [0002] With the rapid development of my country's electric power construction, the scale of the power grid continues to expand, and the construction and operation scale of 220kV voltage level transmission lines is also gradually increasing. Horizontal double-split arrangement, and a spacer bar is installed between the two sub-conductors to avoid mutual adsorption, friction, collision, and even twisting of the sub-conductors within the span, so as to ensure safe operation of the line. [0003] Due to the influence of wire structure, construction quality, weather conditions and other factors, the spacer on the double-split wire is prone to local damage or fracture, which poses a safety hazard to the line, and the installation positions of the spa...

Problems solved by technology

[0003] Due to the influence of wire structure, construction quality, weather conditions and other factors, the spacer on the double-split wire is prone to local damage or fracture, which poses a safety hazard to the line, and the installation positions of the spacer are distributed in different positions of the wire. The distance from the ground is high, the distance from the cross arm of the tower is far, and after the spacer is broken, the maintenance and replacement of the spacer brings great difficulties

At present, the method of replacing the spacer bar of the double-split conductor is: after the power failure of the line, the operator enters the conductor from the cross arm of the tower, and installs a pulley on the split conductor, slides along the conductor to the damaged part of the spacer bar, and finally repairs the spacer bar. Replacement and maintenance; in the process of sliding on the wire to the damaged spacer, if the operator encounters a good spacer, it is necessary to manually pass the trolley over, and then continue to slide to the damaged spacer, which brings great difficulties to the replacement and maintenance of the spacer. Great difficulty, not conducive to the replacement and maintenance of spacers
