Abstract

The invention discloses a ball-head wire clamping device for tightening overhead lines. The device comprises an L-shaped plate, a square plate, three screws with pull rings and a top plate, wherein the L-shaped plate comprises a first straight plate and a second straight plate, a rectangular open groove is formed in one end, which is far away from the second straight plate, of the first straight plate, and a first screw hole is formed in each side of the rectangular open groove of the first straight plate; two fourth through holes are formed in the square plate; the top plate is fixedly arranged on a plate surface of one side, which is far away from the first straight plate, of the second straight plate, and a second screw hole is formed in the top plate; a third screw hole which penetrates through the second straight plate in the thickness direction of the second straight plate is formed in the second straight plate; and the axis of the second screw hole and the axis of the third screw hole are in the same line. The ball-head wire clamping device for tightening the overhead lines has the advantages that pulling ropes are connected with single-cluster porcelain bottles reliably, the safety and the reliability of tightening operation of leads of electric transmission lines can be improved, the working efficiency of the tightening can be improved and the like.

Description

technical field [0001] The invention relates to a ball joint clamp used for wire tightening of overhead lines, in particular to a ball joint clamp used for wire tightening of overhead line conductors in a power system. Background technique [0002] At present, the main method of tightening the wires of transmission lines is to fix the traction rope on the tension clamp. After the wire is tightened, due to gravity, the porcelain bottle is strung under the line, and it needs manpower to twist the porcelain bottle up to the level of the wire and then install it on the cross arm of the pole tower. Guarantee, low line efficiency and high construction cost. [0003] At present, when the wires of a single string of insulators in a transmission line are tightened, a steel wire rope is generally used to tie the traction rope under the second porcelain bottle near the cross arm (the contact between the steel wire rope and the insulator is padded with a sack) to fix the traction rope ...
