Abstract
The invention provides a double-end tackle for hot-line work of a power transmission line. The double-end tackle comprises a square frame body with an opening in one side, wherein an upper pulley which can be arranged on an overhead line for slipping is arranged in an inner frame of the square frame body; a U-shaped bracket which extends downwards is connected with the lower rim of the square frame body; a lower pulley which can be provided with an insulating rope is arranged on the U-shaped bracket; the square frame body is a rectangular frame body; an iron ring is arranged at the upper end part of the rectangular frame body; an openable and closeable magnet-type lock catch for the overhead line for passing in and out is arranged at an opening in the side of the rectangular frame body; the upper pulley is fixed in the inner frame of the rectangular frame body through pin shafts which are transversely arranged in the frames on two sides; the U-shaped bracket which extends downwards is fixed on the lower rim of the rectangular frame body by virtue of a pin; and the lower pulley is fixed on the U-shaped bracket by virtue of a pin shaft. The double-end tackle has the characteristics of being simple in structure, and convenient to use and operate; the time for removing foreign matters is greatly shortened; the work efficiency is greatly improved; and the field hot-line work conditions and requirements are met.
Description
Technical field
What the present invention relates to is a kind of double-end pulley for high voltage transmission line live work, and particularly electric transmission line hot-line removes the double-end pulley of foreign matter aspect, belongs to live line working equipment technology field.
Background technology
In prior art, on transmission line multiple fission conductor after wound foreign matter, sometimes charged dismounting foreign matter is needed, the method of the charged dismounting foreign matter of current employing is, insulating cord is used to walk around overhead ground wire and on insulating cord, the instruments such as hook be installed, by pulling the method for insulating cord to make the instruments such as hook catch foreign matter on wire, now reach by dilatory insulating cord the object making foreign matter depart from wire.But this method adopts the instruments such as hook to be difficult to tackle the occasion handed over across complexity, and mobile operating is inconvenient, dumb, and the efficiency of removing foreign matter is low, weak effect.
Summary of the invention
The object of the invention is to the deficiency of the existence overcoming prior art, and provide a kind of structure simple, use easy to operate, the instrument of dismounting foreign matter can be made to move quickly into foreign matter position, run into simultaneously and hand over the occasion across complexity can sweetly disposition more, the time of removing foreign matter greatly reduces, and operating efficiency improves greatly, meets the double-end pulley of the hot line maintenance of on-the-spot live line working condition and requirement.
The object of the invention is to have come by following technical solution, a kind of double-end pulley of hot line maintenance, it comprises the square frame support body of side opening on one side, in the inside casing of described square frame support body, the top sheave that can be erected at slippage on overhead wire is installed, the lower frame of square frame support body is connected to downward U-shaped support, and on this U-shaped support, be provided with one can the lower sheave of installing insulating rope.
Described square frame support body is rectangular frame body, and the upper end of this rectangular frame body is provided with an iron hoop; The avris opening part of described rectangular frame body be provided with for overhead wire turnover, can the magnet-type snap close of switch.
Bearing pin by laterally installing in the frame of both sides in the inside casing of described rectangular frame body fixes top sheave, and the lower frame of described rectangular frame body fixes downward U-shaped support with pin, and with the fixing lower lower sheave of bearing pin on U-shaped support.
The present invention has following technique effect:
One is that it can meet on-the-spot live line working condition and requirement;
Two is to make dismounting foreign matter instrument move to foreign matter position fast, runs into simultaneously and hands over the occasion across complexity also can process more flexibly;
Three is when processing foreign matter, drag velocity can be made to accelerate, foreign matter can be removed fast;
Four is greatly reduce the time of removing foreign matter, improves operating efficiency.
It is simple that the present invention has structure, use easy to operate, the instrument of dismounting foreign matter can be made to move quickly into foreign matter position, run into simultaneously and hand over the occasion across complexity can sweetly disposition more, the time of removing foreign matter greatly reduces, operating efficiency improves greatly, meets the features such as on-the-spot live line working condition and requirement.
Accompanying drawing explanation

Fig. 2 is side structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1,2, the double-end pulley of a kind of hot line maintenance of the present invention, it comprises the square frame support body 2 of side opening 1 on one side, the top sheave 3 that one can be erected at slippage on overhead wire is installed in the inside casing of described square frame support body 2, the lower frame 4 of square frame support body 2 is connected to downward U-shaped support 5, and on this U-shaped support 5, be provided with one can the lower sheave 6 of installing insulating rope.
Shown in figure, described square frame support body 2 is rectangular frame body, and the upper end of this rectangular frame body is provided with an iron hoop 7; Avris opening 1 place of described rectangular frame body be provided with for overhead wire turnover, can the magnet-type snap close 8 of switch.
Bearing pin 10 by laterally installing in both sides frame 9 in the inside casing of rectangular frame body of the present invention fixes top sheave 3, and the lower frame 4 of described rectangular frame body fixes downward U-shaped support 5 with pin 11, and fix lower sheave 6 with bearing pin 12 on U-shaped support 5.
The present invention improves on the basis of gin block, and install the parts such as magnet-type snap close, pulley additional, wherein the effect of top sheave is along overhead ground wire fast moving; The effect of lower sheave is installing insulating rope; The side openings place of rectangular frame body is provided with magnet-type snap close, makes double-end pulley to be fixed on wire all the time, prevents unbalance stress from causing coaster to come off; The upper end of rectangular frame body is provided with iron hoop, and its effect is: make insulating bar can open the magnet-type snap close of double-end pulley.
The requirement of the live line working that double-end pulley of the present invention not only meets, and the wound foreign matter on multiple fission conductor can be removed more fast, operating efficiency is greatly improved and the power supply reliability strengthened.
