Description

Special wire lifter for concrete pole

technical field

The utility model relates to the field of maintenance of power transmission and transformation overhead ground wires, in particular to a special wire lifter for concrete poles.

Background technique

At present, there are corrosion and other conditions in the overhead ground wires of transmission lines, and they vary with the length of operation years.

The concrete pole is a common pole type in the line, and its structure is somewhat different from the iron tower. There is no fulcrum above the suspension point of the overhead ground wire. If you want to lift the overhead ground wire for maintenance or replace a new clamp, there is no fixed fulcrum. The rope needs to go around the top of the pole to bear the force, and it is not in a straight line with the force during work. Completing the repair or replacing the new clamp requires tedious and complicated work, which not only takes a lot of time and manpower, but also poses a safety hazard. Once the stressed rope slips, it will cause great harm to the people standing on the tower. In addition, there is also a method of manpower lifting. Two or more people stand on the same base pole at the same time and lift the overhead ground wire with their shoulders. This method has great potential safety hazards, because some people standing on the pole step on Some of the foot nails use foot buckles. Once the feet slip, the consequences will be disastrous. At the same time, it is impossible for the personnel to stand still and work for a long time. Moreover, when the blocking distance is too large, the quality of the ground wire is too heavy, and it is not advisable to use the shoulder lifting method.
