Abstract
A wire lifting device for replacing an insulator in a live mode is mainly composed of a metal base, a clamping groove preventing a wire from dropping and sliding away and the insulator connecting the metal base and the clamping groove. A rolling sliding wheel group capable of preventing the wire from being scratched is arranged on the inner side of the clamping groove, a locking device composed of a buckle is arranged at the top of the clamping groove, and the wire is fixed into the clamping groove in the wire lifting process. The lower end of the metal base is provided with a square column block, and a hole penetrating screw which can be fixedly connected with a main insulating supporting rod conveniently is arranged on one side of the square column block. The upper end of the metal base is a cylindrical connecting end and the cylindrical connecting end is connected with the insulator above the cylindrical connecting end. The cylindrical connecting end is provided with a clamping screw used for clamping the connecting part between the cylindrical connecting end and the insulator above the cylindrical connecting end. In addition, a safety warning mark and a safety and conformity mark of an insulating component are pasted on the side edge of the metal base. The wire lifting device has the advantages of being simple in structure, easy to assemble, small in size, high in flexibility, convenient and reliable to use and the like and can effectively improve the working efficiency of 10 kV live needle-type insulator replacing.
Description
Technical field
What the present invention relates to is a kind of 10kV charged for replacement pin insulator wire lifting device, belongs 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 object of the invention is to overcome the deficiency that prior art exists, provide a kind of simple in structure, easy to use and reliable, can help operating personnel's lifting lead wire fast and effectively, improve the lifting device of the replacing insulator under electrified wire of labor operation efficiency.
The object of the invention is to complete 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 present invention has simple in structure, easily assembling, and 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 invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, the lifting device of replacing insulator under electrified wire of the present invention, 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 apparatus of the present invention 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.
