Movable support of insulating operating rod

Abstract

The invention discloses a movable support of an insulating operating rod. The movable support mainly comprises a fixed component at a pole tower side, a telescopic insulating rod component with a pulley, and a stay cord, wherein the fixed component at the pole tower side comprises a fixed mount which is vertically fixed at the pole tower side by virtue of a configured stationary fixture, a transverse telescopic insulating rod component is fixed at the lower part of the fixed mount by virtue of a configured insulating pipe fixing sleeve and an anti-drop sleeve, and a pulley for winding of a lifting rope is arranged at the outer end of the telescopic insulating rod component; the outer end of the telescopic insulating rod component is also connected to the upper end of the fixed mount by virtue of the stay cord; and the telescopic insulating rod component consists of an outer insulating pipe, a connecting sleeve and an inner insulating pipe, one end of the outer insulating pipe is transversely fixed on the fixed mount by virtue of the insulating pipe fixing sleeve and the anti-drop sleeve, and the other end of the outer insulating pipe is connected with the inner insulating pipe by virtue of the connecting sleeve. The movable support has the characteristics of being simple in structure and flexible and convenient in use, increasing operation security and convenience, and the like.

Description

technical field [0001] The invention relates to an insulating operating rod movable support, especially an insulating operating rod movable support for live replacement of insulators and fittings on the wire side of a tension tower of a transmission line, and live wire repair, which belongs to the auxiliary device technology for eliminating defects of electric power equipment field. Background technique [0002] As the insulation configuration of transmission lines increases, the number of effective insulators will inevitably increase (for example, the number of insulators in a single string of 220kV electric railway line tension towers reaches 20 pieces, with a total length of about 3 meters), resulting in The space distance increases, which makes it difficult and potential safety hazard for ground potential electricians to use insulating operating rods to hang soft ladders when the insulators and fittings on the side of the strain tower conductors of the transmission line ...

AI Technical Summary

Problems solved by technology

[0003] One is the ground potential electrician hangs a soft ladder (the weight of the soft ladder is about 15kg) on ​​the wire on the cross arm side of the pole tower. The hands of the operator are used as the fulcrum and the point of force. According to the principle of leverage, the operator needs to overcome the moment of 240 (N m) It is difficult for a single person to do work;

[0004] The second is that there are horizontal and vertical unbalanced forces when hanging the insulating software. To hang the soft ladder on the wire, the operator needs to use the firm member of the iron tower as the fulcrum for the hanging operation, which shortens the effective insulation distance to a certain extent and causes It will cause wear and deformation of the insulating operating rod, and there will be safety hazards in personnel operation and tool operation;
