Abstract
The utility model relates to the technical field of maintenance of high-voltage power transmission line, specifically to a foreign matter removing apparatus of a power transmission line. Foreign matters, such as kites, mulch films, and plastic cloths, may be frequently blown and dropped onto a grounding wire of the overhead power transmission line. If the foreign matters are not removed as soon as possible, accidents, such as short-circuit and trip-out, may occur in the case of rain and thus the safe operation of the power transmission line may be threatened directly. The foreign matter removing apparatus is composed of three parts, i.e., a telescopic insulating rod, a connecting head, and a cutter head, wherein the two ends of the connecting head are internally provided with inner screw threads; one end of the telescopic insulating rod and one end of a supporting rod connected with the cutter head are both provided with external screw threads; the telescopic insulating rod and the supporting rod connected with the cutter head are connected through the connecting head; and the cutter head is formed by two curved knives, wherein the knife edges of the two curved knives are opposite to each other, the knife handles of the two curved knives are connected horizontally, and the blades of the two curved knives are located in the inner side of the two curved knives. During the operation of the foreign matter removing apparatus, neither power cutting nor potential entering is needed. The removing work can be completed through the operation from the ground.
Description
Technical field
The utility model relates to ultra-high-tension power transmission line maintenance technology field, specifically a kind of foreign body eliminating apparatus of transmission line.
Background technology
Transmission line moves for a long time in natural environment, during spring and autumn, strong wind weather, the foreign matters such as kite, mulch film, Polypropylence Sheet are often scraped on the overhead transmission line lead wire and earth wire, if do not extractd as early as possible, meet the rainwater accidents such as tripping operation that will be short-circuited, directly threaten the safe operation of transmission line.Most of hanging wire foreign matter ride on lead wire and earth wire, be wound around firm and solid, difficult drop-off.Although some conventional instruments (as the sickle type cutter head) also can remove, inefficiency, time-consuming, effort, so need the innovation instrument, address the above problem.
Summary of the invention
The purpose of this utility model is to want to provide a kind of foreign body eliminating apparatus of transmission line, can be fast, labour-saving extracts foreign matter.
The technical solution of the utility model is that the transmission line foreign body eliminating apparatus is comprised of telescopic insulating bar, connector, cutter head three parts; The connector two ends are provided with internal thread, and telescopic insulating bar is equipped with external screw thread with support bar one end that is connected cutter head; Telescopic insulating bar connects by connector with the support bar that is connected cutter head; Tool bit part is that two edges of a knife are opposing, shank end tulwar connected horizontally.
Further, the blade of described cutter head is positioned at the inboard of tulwar.
Need not have a power failure while the utility model has the advantages that operation, need not advance current potential, on cross arm of tower, (on ground) can operate excision work.It is low that this instrument has a cost, installs and uses simple and conveniently, guaranteed maintainer's safety, extractd high efficiency, saved manpower and materials.
The accompanying drawing explanation
Fig. 1 is that the transmission line foreign matter is extractd the cutter schematic diagram;
Fig. 2 is the cutter head schematic diagram.
Embodiment
In figure: 1. telescopic insulating bar, 2. connector, 3. cutter head, 4. blade.
From Fig. 1, Fig. 2, the utility model is comprised of telescopic insulating bar 1, connector 2, cutter head 3 three parts; The connector two ends are provided with internal thread, and telescopic insulating bar is equipped with external screw thread with support bar one end that is connected cutter head; It is that two edges of a knife are opposing that telescopic insulating bar 1 connects tool bit part with the support bar that is connected cutter head by connector 2, shank end tulwar connected horizontally; The blade 4 of cutter head is positioned at the inboard of tulwar.
During use, first by insulating bar 1, by connector 2 and cutter head 3, be connected and fixed, this cover instrument is just assembled complete.During work, operating personnel on shaft tower (or on ground) hold insulating bar, with cutter head contact lead wire and earth wire wound foreign matter, adopt the modes such as push-and-pull cutting, winding pulling that foreign matter is separated from lead wire and earth wire and extract, after end-of-job, insulating bar is regained, disassembling tool, complete all operations were.
