Abstract

The invention belongs to the technical fields of maintenance accessory appliance used in lead live working and a method for suspending an insulating flexible ladder, and discloses a special pulley for automatic suspension and a method for suspending an insulating flexible ladder using the same. The pulley is mainly characterized by comprising two insulated hooks, a blocking mechanism and an insulating pulley wheel positioned below the insulated hooks, wherein, the two insulated hooks are fixed together by a pin shaft and are oppositely arranged; the blocking mechanism comprises two support rods of which the tail ends are fixed with the inner pin shaft of the insulated hooks; free ends of the two support rods are respectively connected with two ends of a connection rod though pin shafts; the connection rod is equipped with through holes, and a first insulating rope passes through the through holes; the upper end of the first insulating rope is connected with the insulated hooks through a hanger; and a second insulating rope is wound on the insulating pulley, thus more convenience and highersafety can be provided for picking off and suspending. The special pulley for automatic suspension can be applied to suspending the flexible ladder in the case of live working and is also suitable for transferring tool materials in the case of lead working.

Description

technical field [0001] The invention belongs to the technical field of an auxiliary tool for live wire work maintenance and a method for hanging an insulating ladder, and in particular relates to a special pulley for automatic suspension and a method for hanging an insulating ladder using the pulley. Background technique [0002] The somersault block is an indispensable special tool when the insulating soft ladder is suspended in the live operation of the transmission line. Insulation ladders are required when replacing tension insulators, replacing spacers, repairing wires, replacing anti-vibration hammers, and handling foreign objects in wires, etc. The somersault blocks currently used are not easy to take off and hang, have no locking device, and are easy to wear and tear the ropes. In the process of hanging the insulating ladder, the suspension block or the insulating ladder will fall, which will not only cause damage to the equipment, but also easily cause casualties. ...
