Embodiment Construction

[0021] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Embodiment As shown in the figure, this embodiment provides a transmission mechanism for the ground wire melting automatic wiring device, which drives the opening and closing conductor to move toward or away from the power collector, and the current of the transmission wire of the iron tower is used to melt the tower ground wire. Ice, including motor 1, primary reducer 3, torque limiter 7, universal joint 8, insulated transmission shaft 2, several composite post insulators 14, flange coupling 9, worm gear reducer as secondary reducer 4 The motor 1 can be a DC motor with a manual crank handle 13 that can also rotate when the motor 1 loses power. The first-stage reducer initially decelerates the motor 1. Touch the control switch 10 installed on the side end of the limit plate of the torque limiter 7 to send a control signal to cut off th...

Abstract

The invention provides a transmission mechanism for the ground wire melting automatic wiring device, which drives the opening and closing conductor to direct or separate from the electrical collector, and the current of the power transmission wire of the iron tower is used to melt the ice of the tower ground wire, including a motor and an insulated transmission shaft And the reducer, the motor drives the reducer to rotate through the insulated transmission shaft, and the reducer is connected to one end of the opening and closing conductor and drives the opening and closing conductor to move in a fan plane. The insulating transmission shaft is selected as the rotating element in the transmission mechanism, which meets the insulation and torsional strength, and can meet the transmission requirements.

Description

technical field [0001] The invention relates to the field of overhead power transmission line engineering, in particular to a transmission mechanism for an automatic wiring device for melting ice of ground wires in overhead power transmission line engineering. Background technique [0002] Transmission lines under extreme climate conditions, especially those in some alpine mountainous areas in my country, are often covered with ice in winter. The longitudinal unbalanced tension generated by the uneven ice coating on the transmission wires and ground wires will cause the tower to tilt or bend to the side with high tension. When the design capacity is exceeded, the transmission wires and ground wires will break , hardware falling off, etc., will cause the tower to collapse in serious cases. In addition, because the overhead ground wire on the iron tower is not like the transmission wire, it can resist partial freezing through the heat generated by the load current, and its ic...
