2Or 300mm
2The circuit of cross section lead is compared the increase that has at double, and the model of the structure of insulator string and gold utensil, insulator was with circuit was also all inequality in the past.The power tool of charged for replacement insulator also will be complementary with the structure of insulator string except bearing whole loads of insulator string, and therefore the instrument of original charged for replacement insulator string is all inapplicable.
Summary of the invention
The purpose of this utility model is to provide a kind of 220KV of being applicable to line conductor charged for replacement straight line insulator string instrument.
A kind of 220KV line conductor charged for replacement straight line insulator string instrument, its structural feature is: comprise assembly pulley, insulation rope and jig, one end of insulation rope is walked around an end that is fixed in jig behind the assembly pulley, the other end of jig is provided with the open slot that extends along the length direction of jig, described open slot is divided into two of front and back with the respective end of jig, and that end downside that has open slot at jig is provided with location notch.
During use, one end of insulation rope is fixed on the jig, to insulation again rope is walked around behind the assembly pulley that hangs on the cross-arm end by artificial or adopt mechanical stretch, that end that again jig is had open slot embeds in superposed two yoke plates of duplex suspension insulator lower end, and be jig fulcrum (be about to location notch that jig has that end downside of open slot and be supported in P-30 link plate place in the middle of two yoke plates) with the P-30 link plate place in the middle of two two yoke plates, the duplex bowl head place that two yoke plates are connected with insulator string to be changed is a gravity station, carrying the cotton rope junction with jig and the strong insulation of superelevation is impetus, form the operating mode of lever stress, to realize the replacing of straight line insulator string.Adopt this charged for replacement straight line insulator string instrument, can not only significantly reduce to promote the be subjected to force intensity of lead, also bring into play the effect of the two insulator strings backup protection each other of duplex suspension insulator with package unit.
Described assembly pulley is a kind of fixed pulley.
In use fixed pulley is hung on the cross-arm end.
Described fixed pulley is fixed on the cross-arm by pulley yoke, and pulley yoke is connected with cross-arm by bearing pin.
Adopt the mode of bearing pin to be connected with between the pulley yoke of fixed pulley and the cross-arm, make both connections all very convenient with dismounting.
Described jig also is provided with the open slot that jig is divided into two of front and back with that end that the insulation rope is connected, be provided with on two in the front and back of jig the through hole that connects before and after the jig two is arranged, one end of insulation rope is provided with the fixture that can snap in this open slot, and fixture is provided with through hole.
The insulation rope is installed on jig, the fixture of insulation end portion is filled in the respective end of jig, and make the through hole of the through-hole alignment jig of fixture, then fix with latch.
Described location notch is a kind of deep-slotted chip breaker.
Free end at the insulation rope is provided with wire grip.
Described insulation rope is polyparaphenylene's benzo twoport oxazole cordage.
In sum, advantage of the present utility model is:
By this charged for replacement straight line insulator string instrument, employing will be connected the cotton rope of carrying on the jig, turn to fixed pulley to cause ground by the aluminium alloy insulation that hangs on the cross-arm end,, put forward the tense-lax of cotton rope by operation manual manipulation control on the alternative tower of ground staff by craft or wire grip.Thisly carry line method not only instrument is simple and can guarantee to put forward traditional thread binding enough effective insulated lengths that is equipped with, more can adapt to the straight line insulator string charged for replacement of different types, different length.It is simple that this project of making has tool operation, the high and safe and reliable again characteristic of work efficiency, and its convenience is better than screw mandrel method and the rope method that present live line working is generally adopted.
