Replacing insulator under electrified wire lifting device
Technical field
The utility model relates to a kind of 10kV charged for replacement pin insulator wire lifting device, belong to medium voltage electricity overhead transmission line equipment operation and maintenance technical field.
Background technology
The wire of overhead power line, is to utilize porcelain insulator and gold utensil to be connected and fixed on shaft tower, needle porcelain bottle mainly play wire vertical support and guarantee wire and the earth between insulating effect.The Main Function of lifting wire is that live wire is separated with needle porcelain bottle, makes it depart from live part, afterwards needle porcelain bottle is changed.Lifting wire is outbalance one ring in job step.
10kV live-line replacing pin insulator adopts the operation of the little arm lifting lead wire of aerial lift device with insulated arm method at present, for preventing damage wires in lifting process, wire external demand promotes after insulation thread-protected tube is set again, and hoisting tool is soft insulating rope, wire easily swings, and easily staff's safety is caused to adverse effect.For preventing that wire dropping from also needing to arrange the measures such as backup protection, increased job step.In order to improve the operating efficiency of 10kV charged for replacement needle porcelain bottle, reduce operation and consume artificial quantity, promote the security reliability of operation simultaneously, study new-type wire lifting device imperative.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, easy to use and reliable, can help operating personnel's lifting lead wire fast and effectively, improves the lifting device of the replacing insulator under electrified wire of labor operation efficiency.
The purpose of this utility model completes by following technical solution, the lifting device of described replacing insulator under electrified wire, it mainly by metab, prevent that the sliding draw-in groove running of wire dropping and the insulator of connection metal base and draw-in groove from forming, described draw-in groove inner side has the rolling pulley group that prevents that wire from scratching, its top is provided with the locking device consisting of buckle, and in lifting wire process, wire is fixed in draw-in groove.
The lower end of described metab is square column piece, and a side of this square column piece disposes the convenient perforated screw being fixedly connected with insulation main support rod; The upper end of described metab is cylindrical link, and this cylindrical link is connected with the insulator of top.
On described cylindrical link, be provided with for tightening up the clamping screw with top insulator connecting portion; Separately at the side of metab, be pasted with the safe mark of conformity of safety alarming and identifying and insulating component.
The utlity model has simple in structure, easily assembling, the feature such as volume is little, and flexibility is large, easy to use and reliable, can effectively promote the operating efficiency of 10kV charged for replacement pin insulator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, the lifting device of replacing insulator under electrified wire described in the utility model, it is mainly comprised of with the insulator 2 of draw-in groove 3 metab 1, the draw-in groove 3 that prevents the sliding race of wire dropping and connection metal base 1, and metab 1 is fixed on live line working bucket arm vehicle insulation main support rod; Described draw-in groove 3 inner sides have the rolling pulley group 8 that prevents that wire from scratching, thereby prevent in lifting wire process the phenomenons such as wire wearing and tearing, and its top is provided with the locking device 9 consisting of buckle, and in lifting wire process, makes wire be fixed in draw-in groove 3; Effectively prevent that wire swing from coming off, and works the mischief to staff's personal safety.
The lower end of described metab 1 is square column piece 4, and a side of this square column piece 4 disposes the convenient perforated screw 5 being fixedly connected with insulation main support rod; The upper end of described metab 1 is cylindrical link 6, and this cylindrical link 6 is connected with the insulator 2 of top.
On described cylindrical link 6, be provided with for tightening up the clamping screw 7 with top insulator 2 connecting portions; Separately at the side of metab 1, be pasted with the safe mark of conformity 10 of safety alarming and identifying and insulating component.
While utilizing the utility model device lifting lead wire; only base need be embedded to insulator crossarm inwall; use screw rod fixing; little, the easy assembling of this device volume, flexibility are large, easy to use, in lifting process by after locking device locking; without backup protection is set; safe ready, can improve replacing insulator under electrified labor operation efficiency greatly, reduces labor strength.
