<p>PROBLEM TO BE SOLVED: To provide a snow-removing robot device, capable of moving mechanically in a longitudinal direction of an electric line by making reciprocating motions, thereby transmitting the moving distance at the drive side of a spiral rode for removing snow to the opposite side with the least decrease in the moving distance in the reciprocating movement. SOLUTION: A tension member 6 is placed along an electric cable 2 and a snow- removing spiral rod 5 is loosely wound around the cable and the rod 5 in a longitudinal direction and the member 6 is tied with wires at equal intervals. A main body 3 of a snow-removing robot is connected to one end side of the spiral rod 5 and the tension member 6, a retaining spring 7 is connected to the other end side of the rod 5 and the tension member 6, and a pulling force of the main body 3 of the snow-removing robot and a returning force of the retaining spring are used for giving the reciprocating motion to the spiral rod 5 and the tension member 6 in a longitudinal direction. The main body 3 of the snow-removing robot is fixed to one side of the span, the retaining spring 7 is fixed to another side of the span, and the spiral rod 5 and the tension member 6 are desired to be attached continuously to the whole length of the cable between both sides of the span, and the retaining spring 7 permits the displacement of more than 1 pitch of the snow-removing spiral rod 5.</p> |
