Overhead line pay-off mechanism for power transmission and transformation

The invention discloses an overhead line pay-off mechanism for electric power transmission and transformation, and relates to the technical field of electric power. Comprising a movable base, a pay-off device is fixedly installed at the top of the movable base, the pay-off device comprises a front plate and a rear plate, the front face of the front plate is rotationally connected with a transmission framework, and a pay-off framework, a guide framework and an abutting framework are arranged between the front plate and the rear plate. By arranging a guide framework, a rotating shaft is utilized to promote a ball to drive a hanging ring to slide through a closed groove, so that the hanging ring moves back and forth in a reciprocating manner above a pay-off shaft, the movement of the hanging ring drives an electric wire to perform orderly winding movement on the surface of the pay-off shaft, and a gap between cables is reduced to the minimum; the space of the equipment is effectively saved, the same pressure ang
