Abstract
Be used for special hoist and mount fixture of high tension transmission line composite insulator, it is mainly met by two halves joint ring and forms to but the intermediate formation at two halves joint ring has the joint ring of joint in composite insulator metal tip, half joint ring for half fixed snap ring, second half is half snap ring of activity, fixed half a snap ring tip hinging another half snap ring of activity with the pin, another tip of half fixed snap ring hinges with the pin has the movable screw rod that disposes the nut, corresponding to the activity screw rod, set up the joint groove that confession activity screw rod outside -in card is gone into at the corresponding tip of half snap ring of activity, fixed half snap ring meet and have one to be used for the lifting rope to restraint the rings of knot usefulness, it has simple structure, and convenient to use is reliable, can protect silicon rubber composite insulator its surperficial glaze and full skirt in the installation not to receive the damage, improves transmission line insulation level, increases life, guarantees characteristics such as electric wire netting safe operation.
Description
Technical field
The utility model relates to a kind of for high voltage power transmission line composite insulator special hoisting jig, belong to ultra-high-tension power transmission line maintenance operation lifting device technical field.
Background technology
In prior art, one of traditional insulator hanging method is: tied up to by rope on composite insulator full skirt in hoisting process, this kind of hanging method winches to the glaze surface damage very easily causing composite insulator in scope of operation process rising, or causes that composite insulator is damaged or tension set; And silicon rubber synthetic insulators surface glaze is once after impaired, just there will be following problem: 1), reduce insulating property, easily there is the breakdown accident under power-frequency voltage; 2), silastic surface performance degradation, in operational process composite insulator full skirt hardening or elasticity weaken easily tear or surface hydrophobicity decline phenomenon, shorten normal work-ing life; 3), moisture resistance weaken, plug makes moist and hydrolysis reaction will occur, reduce composite insulator physical strength, cause fall string accident.
The two of traditional insulator hanging method are: the direct colligation of rope is lifted by crane in composite insulator metal end, although this kind of hanging method operation is simple, do not need to increase other off-set facility, but there are two shortcomings: 1), composite insulator metal coupling end and hanging point place nargin little, not easily tether conciliate rope; 2), the easy slippage of knot, cause high-altitude junk, impact safety in production.
The three of traditional insulator hanging method are: increase protective layer at composite insulator silicon rubber place and lift by crane; although this kind of hanging method operation is simple; decrease mnila rope in lifting process, cause the glaze abrasion of composite insulator surface; but owing to composite insulator and rope exist deadweight, lifting process still can cause the damage of insulator full skirt or distortion.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art existence; and provide a kind of structure simple; easy to use and reliable; silicon rubber synthetic insulators its surface glaze and full skirt in installation process can be protected not to be damaged; improve transmission line insulator level; increase work-ing life, ensure electric power netting safe running for high voltage power transmission line composite insulator special hoisting jig.
The purpose of this utility model completes by following technical solution, a kind of for high voltage power transmission line composite insulator special hoisting jig, it connects ring primarily of two halves card and has connected, and the intermediate formation connecing ring at two halves card has the card that can be connected in composite insulator metal end to connect annulus, described half card connects ring for fixing half snap ring, second half is movable half snap ring, described half snap ring one end pin-hinges of fixing another movable half snap ring, the other end pin-hinges fixing half snap ring has a moving screw being configured with nut, corresponding to described moving screw, respective end at movable half snap ring offer for moving screw block inside lateral into buckling groove, described half snap ring of fixing is connected to one for the suspension ring of lifting rope binding.
As preferably: described suspension ring are an annulus, it is integrally connected with described half snap ring of fixing by side connecting end portion; The described both ends fixing half snap ring connect, respectively to movable half snap ring, the pin Connection Block that side is respectively arranged with protrusion, and connect described activity half snap ring and moving screw on pin Connection Block respectively with pin.
As preferably: described suspension ring are connected on the described one end fixing half snap ring mutually by side connecting end portion one; The described one end being hinged with moving screw on half snap ring of fixing is provided with the connection block holding protrusion laterally, and is provided with described pin Connection Block on this connection block.
It is simple that the utility model has structure, it may also be useful to convenient and reliable, silicon rubber synthetic insulators its surface glaze and full skirt in installation process can be protected not to be damaged, it is to increase transmission line insulator level, increases work-ing life, ensures the features such as electric power netting safe running.
