Description
Technical field
The invention belongs to strain rod tower field of operation, more particularly to a kind of strain insulator composite insulator outlet flat ladder.
Background technology
At present, it is on strain rod tower on transmission line of electricity to use composite insulator more, because composite insulator has mechanical performance
Good, it is strong that anti-pollution dodges ability, it is anti-aging the advantages of.It is but past when tear open the work of lapping drainage wire on anchor support because of need of work
Toward that can meet difficulty, because composite insulator can not bear operating personnel's own wt, cause operating personnel can not be from insulator
Climb to and operation is carried out on conducting wire.
Although can solve the problems, such as disengaging conducting wire using existing flat ladder, there are inconvenience in use.Flat ladder
Fixed with tower body and use brachycephaly rope improving bud grafting, such as binding sling loosens in use, and flat ladder will depart from from tower body, cause
Operating personnel falls.To ask sling to fasten, operating personnel often knots repeatedly in process of binding, not only loses time, but also is torn open
Except work is made troubles.In addition, operating personnel is climbed into wire process using flat ladder from tower body, it is most likely that due to flat ladder ladder body
Smooth and easily stir and cause itself to fall, the process that climbs out of not only expends muscle power, and there are certain security risk.
The content of the invention
The present invention is to overcome above-mentioned deficiency of the prior art, there is provided a kind of easy to operate, improve operation
The strain insulator composite insulator outlet flat ladder of security.
To achieve these goals, the present invention uses following technical scheme：
