<p>PURPOSE:To control the speed of a suspended working machine independently of the existence of a projection article installed on a power transmission line and facilitate the getting-over on the projection article on the power transmission line by the swing of a swing member by controlling the revolution of a gear by operating a break mechanism. CONSTITUTION:In the case of a suspended working machine for power transmission line for four-conductor power transmission line, a supporting rod 3 is arranged on a pair of power transmission lines 1 on the upper part side, and a traveling device having a pair of rollers 5a and 5b is installed through a supporting shaft 4 at both the edges of the supporting rod 3. Accordingly, a swing piper 6 is supported in swingable manner on a supporting shaft 4. And a swing arm 7 is fixed on the flange 6a of the swing pipe 6, and a base plate 8 is fixed on the flange 6b. Rollers 5a and 5b which travel on the power transmission line 1 are installed turnable manner at both the edges of the swing arm 7 and the base plate 8. Further, a gear 3 is supported in rotatable manner on the supporting shaft 4 between the supporting rod 3 and the base plate 8, and a brake drum 14 is formed integrally on the side part of the gear 13, and a belt member 15 which is made of metal and connected to a brake driving mechanism 21 is laid on the brake drum 14.</p> |
