Abstract
The utility model discloses an arc extinguishing pulley used for a powered-on line and belongs to technical field of design and production of a wire-hanging pulley used for power transmission line wire maintenance. A pulley hook equipped with a wire-clamping locking rod is disposed on a movable shaft. A pulley wheel is arranged on a pulley wheel seat. The arc extinguishing pulley used for a powered-on line is produced by insulating material and the using method of the arc extinguishing pulley used for a powered-on line is that the pulley hook is hung on the steel wire of a power transmission line, that the pulley wheel is bound with an operating rope ladder, and that an operating worker climb up the rope ladder to an operating location and then erect the locking rod in order to lock the steel wire and repair the wire. The practical arc extinguishing pulley used for a powered-on line has simple structure and is easy to use. The wire-clamping locking rod is capable of effectively preventing the hook from peeling in order to guarantee operating safety. Compared with a conventional outgoing line ladder, safety factor of the arc extinguishing pulley used for a powered-on line is substantially increased. Because of the insulating-material-produced arc extinguishing pulley used for a powered-on line, possibility of discharging and arcing when the pulley is mounted and removed is effectively prevented so that safety is guaranteed and a problem in the conventional product is resolved.
Description
Technical field
The utility model belongs to design and the manufacturing technology field that the hanging wire coaster is used in the transmission line wire maintenance.
Background technology
In the transmission line maintenance activity, when meeting disconnected burst of phenomenon of wire, all need to the outlet ladder be installed at the steel tower cross-arm and carry out maintenance activity at present.And it is very loaded down with trivial details that the outlet ladder is installed.Rock swing because outlet ladder is high-level again, it is also very dangerous that the maintenance personal will move to the maintenance position from the outlet ladder.In addition, adopt this mode that wire is just keeped in repair and must carry out under power-off condition, so again can be to industrial and agricultural production and civilian causing damage and inconvenience.
Summary of the invention
For above-mentioned situation, the purpose of this utility model provides a kind of hanging wire coaster that can use in charged situation, solves the variety of issue that existing method for maintaining exists.
The utility model is to address the above problem the technical scheme of taking to be: there is a movable axis bottom in the coaster main body with connecting draw-in groove, connecting on the draw-in groove, links up with coaster on movable axis.On coaster hook with card line deadlock lever.Below connecting draw-in groove, a pulley base is arranged, on pulley base with pulley.The utility model adopts insulating material to make.Its using method is: coaster is linked up with lodge on the transmission line steel wire, bondage operating rope ladder on pulley.Operating personnel climb up job position along soft operating ladder, and deadlock lever is erected, and make its locking steel wire, then wire are keeped in repair.Wait keeping in repair under the complete operating personnel behind ground, rock rope ladder the coaster main body is tilted, steel wire skids off from the hook opening and drops.The utility model is simple in structure, and is convenient and practical.Because can prevent effectively that with card line deadlock lever hook from coming off, and ensures job safety.Adopt the utility model operation with respect to existing outlet ladder, coefficient of safety increases greatly.Because this product adopts insulating material to make, can prevent effectively that coaster from putting a little and the possibility of arcing when installation and removal again, guarantee safety.Solved the problem that existing product exists.
