Abstract
Provided is a power assisting device used for replacing a tension insulator string of an overhead transmission line. The power assisting device used for replacing a tension insulator string of an overhead transmission line is characterized by comprising a crossbeam, a fixed rack, a connecting plate, a suspension ring, and a connecting ring. The fixed rack is welded on the top of the tail end of the crossbeam. The connecting plate is welded on the front of the fixed rack. The suspension ring is hinged to the lower part of the front of the cross beam. The connecting ring is hinged to the upper part of the front of the crossbeam. The power assisting device used for replacing a tension insulator string of an overhead transmission line has advantages of a simple principle structure, reliable intensity, shortening operating time, reducing working strength of operating workers, being suitable for continuous operation, and substantially increasing work efficiency.
Description
Technical field
The utility model relates to the aid of changing strain insulator string, particularly a kind of overhead transmission line change the strain insulator string power assisting device.
Background technology
During power transmission sequence strain tower center line replacing insulator string, because insulator string is in level, and coaster is in cross-arm upper horizontal iron place, has restricted the position, Heave Here, need the operating personnel to push insulator string to side of wire was from cross-arm side, then connected by the side of wire was operating personnel.In practical operation, there are many difficult points.
Because insulator string length generally surpasses 2.5m, so self will be in vacant state with insulator string during cross-arm side operating personnel implementation and operation always, very easily personal and equipment be damaged.Common insulator string standard weights generally in the 100kg left and right, often needs the operating personnel manually insulator string to be held in the palm and holds up correction in operation.Operating personnel's operation easier and labour intensity have greatly been increased.Power transmission sequence is changed insulator as the large-scale operation that often has, and adopts all the time old-fashioned operational method greatly to extend the activity duration, increases operating personnel's fatigue strength.Be not easy to work continuously, greatly reduce operating efficiency.Therefore be badly in need of a kind of renewal instrument be auxiliary faster completing.
The utility model content
The purpose of this utility model is for the ease of power transmission sequence strain tower center line replacing insulator string, and the spy provides a kind of overhead transmission line to change the strain insulator string power assisting device.
The utility model provides a kind of overhead transmission line to change the strain insulator string power assisting device, it is characterized in that: overhead transmission line is changed the strain insulator string power assisting device, comprises crossbeam 1, fixed mount 2, connecting plate 3, suspension ring 4, connecting ring 5;
Wherein: fixed mount 2 is welded on crossbeam 1 afterbody top, and connecting plate 3 is welded on anterior position on fixed mount 2, the lower hinge in suspension ring 4 and crossbeam 1 the place ahead, the upper articulation in connecting ring 5 and crossbeam 1 the place ahead.
On described connecting plate 3 with through hole.
Afterbody and the electric wire tower of crossbeam 1 are hinged, and adjustable bracing wire is connected on connecting ring 5, and suspension ring 4 connecting insulator strings drive insulator string by drawing adjustable bracing wire.
Advantage of the present utility model:
Overhead transmission line described in the utility model is changed the strain insulator string power assisting device, and theory structure is simple, and intensity is reliable, shortens the activity duration, reduces operating personnel's working strength.Be suitable for working continuously, greatly improved operating efficiency.
Description of drawings
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is that overhead transmission line is changed strain insulator string power assisting device theory structure schematic diagram.
Embodiment
The present embodiment provides a kind of overhead transmission line to change the strain insulator string power assisting device, it is characterized in that: overhead transmission line is changed the strain insulator string power assisting device, comprises crossbeam 1, fixed mount 2, connecting plate 3, suspension ring 4, connecting ring 5;
Wherein: fixed mount 2 is welded on crossbeam 1 afterbody top, and connecting plate 3 is welded on anterior position on fixed mount 2, the lower hinge in suspension ring 4 and crossbeam 1 the place ahead, the upper articulation in connecting ring 5 and crossbeam 1 the place ahead.
On described connecting plate 3 with through hole.
Afterbody and the electric wire tower of crossbeam 1 are hinged, and adjustable bracing wire is connected on connecting ring 5, and suspension ring 4 connecting insulator strings drive insulator string by drawing adjustable bracing wire.
