Riding type threading wire-suspending device for 500 kV overhead ground wires

Abstract

The invention discloses a riding type threading wire-suspending device for 500 kV overhead ground wires. The riding type threading wire-suspending device comprises an inverted V-shaped support, wherein a horizontal plate facing to the inner side is arranged at one end of the support, and a horizontal base is arranged at the other end of the support; a through hole is formed in the horizontal base, and a cambered surface is arranged at the upper part of the through hole; a ball head nut is arranged in the through hole, and the ball head of the ball head nut is matched with the cambered surface of the through hole; a threaded bushing is arranged on the ball head nut in a matching manner, and a rotary sleeve is arranged on the threaded bushing; a handle is mounted at the outer part of the rotary sleeve, and a hook is arranged at the lower part of the threaded bushing. The riding type threading wire-suspending device is directly buckled on a cross arm through the support and is close to the cross arm, so that the moment is reduced, and deformation is prevented. As the ball head nut can be matched with the cambered surface of the through hole in a swinging manner, the riding type threading wire-suspending device can swing in any direction, avoids deflection caused by heavy wind, and is effectively protected.

Description

technical field [0001] The invention relates to a kind of electric power equipment, in particular to a straddle-type set thread hanger for 500kV overhead ground wire. Background technique [0002] The wire hanger is the main tool for the replacement of 500kv overhead ground wires and suspension wire accessories. The disadvantages of the existing wire hangers are: the hanging point of the wire tensioner is far from the cross arm of the overhead ground wire, exceeding 20cm, and the torque is too large, which makes it difficult to follow the line. The channel steel in the direction is deformed under compression; the wire hanger can only swing along the line, but cannot swing horizontally with the line. When encountering wind deflection, the wire will deflect laterally, and the force direction of the wire hanger is wrong, resulting in damage to the wire hanger. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to pr...
