The utility model has the advantages that:
The utility model provides a kind of charged for replacement 500kV circuit tangent tower insulator string general insulation pull-rod, this insulation pull-rod has three kinds of forms, these three kinds of forms all are to guarantee insulation distance by canned paragraph, regulate pull-rod length in all the other length ranges, satisfy the length requirement of the stressed system of bypass.First kind is the adjustable pull-rod of bushing type, and it has two to adjust the position, and the intermediate casing place can adjust pull-rod length, and jig installation position, lower end also can be adjusted, and it is big to adjust distance like this, and the position cooperation can be satisfied the long requirement of multiple string up and down, and adjustment amount is wide on a large scale.Second kind is the adjustable pull-rod of fork-join bullet pin formula, and middle fork-join part is used the hoodle pin, and easy for installation, dismounting is fast, and there is adjustment hole the lower end, can adjust arbitrarily and satisfy the long requirement of string, and it installs fast, and is convenient, and certain adjustable range is arranged.The third is to prolong the adjustable pull-rod of joint type, and the middle interconnecting piece position can connect numerous prolongation joint arbitrarily, and jig installation position, lower end also can be adjusted, also there are two to adjust the position, jig installation site, upper and lower cooperation are strengthened adjustment amount and are satisfied the long requirement of string, and adjustment amount is wide on a large scale.Three kinds of adjustable pull-rods all can adapt to multiple tower, string long, can guarantee enough insulation distances again, adjusting range is big, adapts to tower, serial type is many, can guarantee enough insulation distances again, solves the versatility problem of pull-rod.This cover pull-rod provided by the utility model all adopts standing part control insulation distance, pull-rod is adjusted in any case can both satisfy, minimal security insulation distance and remaining unchanged.
Description of drawings
Fig. 1 is the structural representation of the adjustable pull-rod of straight line bushing type that proposes of the utility model;
Fig. 2 is the structural representation of the adjustable pull-rod of straight line fork-join bullet pin formula that proposes of the utility model;
Fig. 3 is the structural representation that the straight line that proposes of the utility model prolongs the adjustable pull-rod of joint type.
Embodiment
The utility model provided a kind of and can use at multiple tower, use under the multiple string elongate member, adjustable general insulation pull-rod, this general insulation pull-rod comprises the pull-rod body, and the pull-rod body is provided with the adjustable length device that is used to adjust the pull-rod length distance.
The adjustable length device is bushing type adjustable length device, fork-join formula adjustable length device or prolongs joint type adjustable length device.
When the adjustable length device was bushing type adjustable length device, bushing type adjustable length device comprised the sleeve pipe that is arranged on the pull-rod body; Be provided with pin-and-hole on sleeve pipe and the pull-rod body; Pull-rod body and sleeve carry out adjustable length by pin and pin-and-hole.
Pin-and-hole on the sleeve is one or more, and the pin-and-hole correspondence on the pull-rod body also is one or more.
When the adjustable length device was fork-join formula adjustable length device, the end of pull-rod body was provided with connector; Be provided with the hoodle pin in the middle of the connector, connect by the hoodle pin on the connector between adjacent two pull-rods.
The adjustable length device is when prolonging joint type adjustable length device, and the end of pull-rod body is provided with and is used for the joint that is connected with adjacent pull-rod body; Joint is a plurality of.
Referring to Fig. 1, this general insulation pull-rod is the adjustable pull-rod of bushing type, is to utilize a sleeve pipe to be set on upper and lower two pull-rods, and join with two pull-rods respectively and be drilled with several pin-and-holes, during operation, as long as press Len req, select suitable pin-and-hole to insert good pin, but change the just operation of pull-rod length.This pull-rod, centre and bottom be adjustable length all, uses more convenient.The adjustable pull-rod of 500kV straight line bushing type is when setting up the stressed system of bypass, and no matter which kind of tower, string are long, all can be connected with wire grip, hang up properly play card, and the random pin on the adjustment adjusting sleeve pipe satisfies the length requirement of the stressed system of bypass.Can't satisfy as length, pull-rod lower end adjustment hole also can be used to change card position down, regulates pull-rod length.
