In long-term use, people have also found that although the existing engineering plastic wedge-shaped strain clamps are convenient and practical, there are still certain hidden dangers: when the tensioned wires are subjected to wind swing and thermal expansion for a long time Sliplines are likely to occur after cold shrinkage and irresistible external force. When the tensioned wires slip in engineering plastic wedge-shaped tension clamps, it is very easy to cause other unforeseen and unsafe major accidents. happened

The invention discloses an additional anti-skid device matched with strain hardware fittings. A specially shaped butting bolt is arranged in a butting bolt screw hole at the middle of a top part of an additional butting bend room, the middle part of the additional butting bend room is provided with a threading slide opening, and a bottom part is provided with a wire falling huge hole. The additional anti-skid device is characterized in that after a leftover tensioned conductor is run through the threading slide opening in the additional butting bend room before being slided to a root part of a rear end of a train wire clamp of the tensioned conductor, the conductor staying in the threading slide opening can be butted firmly by the specially shaped butting bolt in the butting bolt screw hole of the top part of the additional butting bend room; after forceful screwing of the specially shaped butting bolt in the butting bolt screw hole continues, the conductor being butted downward can be enabled via the wire falling huge hole to completely positioned in the huge hole of the wire falling huge hole.
Description
technical field [0001] The invention relates to the construction of overhead lines, and directly relates to an additional anti-skid device matched with tension fittings, and is especially suitable for use with tension clamps after tensioning. Background technique [0002] In the construction of fully insulated overhead lines, the metal fittings for fixing and tensioning the line terminals are all completed by recently designed engineering plastic wedge-shaped tension clamps. In long-term use, people have also found that although the existing engineering plastic wedge-shaped strain clamps are convenient and practical, there are still certain hidden dangers: when the tensioned wires are subjected to wind swing and thermal expansion for a long time Sliplines are likely to occur after cold shrinkage and irresistible external force. When the tensioned wires slip in engineering plastic wedge-shaped tension clamps, it is very easy to cause other unforeseen and unsafe major accide...
