Device and method for lifting wire during distribution line construction

Abstract

The invention discloses a device and a method for lifting a wire during distribution line construction and belongs to the technical field of distribution line erection construction. The device comprises a stand column, a support rod and a wire tightening mechanism, wherein the support rod is fixedly connected with a first casing pipe; an inclined strut is arranged between the stand column and the support rod, one end of the inclined strut is fixedly connected with the support rod, and the other end is fixedly connected with a second casing pipe; a guide pulley is mounted at the free end of the support rod; a U-shaped hanging ring is fixedly connected in the middle of the stand column; a U-shaped hook is fixedly connected at the bottom end of the stand column; one end of a connecting frame of the wire tightening mechanism is fixedly connected with a hook matched with the U-shaped hanging ring; a steel wire rope of the wire tightening mechanism winds around a roller, and the free end of the steel wire rope penetrates through the guide pulley to be connected with a shackle. The device is simple in overall structure and convenient to mount, the wire is lifted in place quickly, operating conditions of workers are improved, the labor intensity of the on-pole workers is reduced, and potential safety hazards during construction are reduced.

Description

technical field [0001] The invention relates to a wire lifting device and a lifting method in the construction of distribution lines, belonging to the technical field of distribution line erection construction. Background technique [0002] During the construction process of unwinding the distribution line, after tightening the wires to the designed sag, workers need to lift the wires from the pay-off block to the supporting insulators. Due to the lack of suitable working tools, the workers on the pole often use shoulder The operation method of carrying is to carry the wire from the tackle to the insulator, especially the middle-phase wire needs to be lifted by 60-80cm, and the lifting distance is relatively long. The current distribution main line often adopts JKLGYJ-240 overhead insulated wire, the wire diameter is thicker and the weight is heavier. During the entire lifting process, the staff's shoulders and waists need to bear a lot of strength, bloodstains are often st...

Problems solved by technology

There are also many wire tensioners, but the existing wire tensioners are slow and inefficient to complete basic wire tightening or loosening, and cannot quickly complete the wire tightening and loosening actions when the wire is lifted or dropped. The above-mentioned dangerous situation occurs, so there is an urgent need for a wire lifting device and a lifting method that saves time and effort during the construction process and avoids harming the construction personnel.
