Description
Technical Field
The present invention relates to a wire takeup device, and more particularly to a double split wire takeup device.
Background
The topography of coastal mountain areas is large in height difference of the power transmission line, and after the vibration damper blows and vibrates, the wire clamps are loosened, so that the vibration damper slides along the line from the high-topography towers to the low-topography towers. Because the wire clamp loosens and is influenced by wind power and can shake, the wire is rubbed continuously, and the damage and strand breakage of the wire are caused for a long time. Meanwhile, in typhoons on coastal sides, sharp foreign matters such as iron sheets of workshops fly to cause strand breakage of the wires. These lead damage conditions occur on the lead between the two towers, and the defect positions are not fixed randomly, so that the lead needs to be repaired by operators.
The 220kV transmission line adopts double split conductors, and as no spacing rod is arranged between the upper sub-conductor and the lower sub-conductor, in the outgoing process of operators, the longer the outgoing line is, the larger the separation distance between the upper sub-conductor and the lower sub-conductor is, as the lower sub-conductor is subjected to the extra load of the weight of the operators and the weight of an outgoing tool. One of the traditional methods is that an operator shifts to the lower part of an operation place through the lower sub-conductor, and tightens the upper sub-conductor and the lower sub-conductor to operate by using an insulating rope and manpower; and the second method is to use insulating ropes to bind upper and lower sub-wires at intervals of 15 meters to avoid wire separation until the operation point is reached. The traditional method is complicated in operation steps, high in physical strength requirement on operators and low in operation efficiency.

When the double-split wire tightening device is used, the upper sub-wire tightener and the lower sub-wire tightener are mounted on the lower sub-wire pulley fixer, the movable door of the lower sub-wire pulley fixer is opened, the lower sub-wire is clamped into the movable door, the movable door is locked, then the insulating ropes in the upper sub-wire tightener and the lower sub-wire tightener are strung into the fixing holes of the side plates of the upper sub-wire following pulley, the two side plates of the upper sub-wire following pulley are hung on the wires in a staggered angle, then the insulating endless ropes are penetrated out of the upper through holes of the inclined sections of the side plates of the other side and then are bound and fixed, after the double-split wire tightening device moves to the right after the worker moves to the right, the staff rotates the screw tightening locating piece, and then the insulating ropes of the tightener are tightened again, so that the tightening of the upper sub-wire and the lower sub-wire is realized.
The locating piece is an arc-shaped face on the locating face facing the pulley.
The positioning surface is arranged to be an arc surface, so that the movement of the lower sub-wire pulley fixer relative to the wire is smoother.
The locating piece is of a U-shaped structure, one side of two sides of the U-shaped structure is used for fixing the screw rod, and the other side of the U-shaped structure is used as a locating surface.
By adopting the U-shaped structure, the bottom edge of the U-shaped structure can lean against the side edge of the frame-shaped fixing frame, so that the stability of the positioning piece can be improved.
The lower sub-wire pulley fixer is characterized in that two pulleys are arranged in the frame-shaped fixing frame in a front-back mode, and the positioning piece is arranged between the two pulleys.
Two pulleys are arranged in the lower sub-wire pulley fixer, so that the stability of the double-split wire tightening device can be improved.
