Abstract
The utility model discloses a dedicated extension ladder for replacing an insulator; the dedicated extension ladder comprises a lifting hook, an electromagnetic induction shielding insulating rod and a ladder post unit, wherein the ladder post unit comprises ladder tubes; bottom ladder tubes of the ladder post unit are connected with the electromagnetic induction shielding insulating rod which is connected with the lifting hook; the ladder post unit comprises at least two hollow ladder tubes which have different pipe diameters and are connected in series; each ladder tube is provided with a groove which is internally provided with a pedal; and the pedal is articulated with the ladder tubes. The dedicated extension ladder is firmly connected and the length of the extension ladder can be adjusted. The pedal on the ladder tube and the ladder tubes are an integrated structure; and when the ladder tubes stretch, the pedal is folded into the groove. The dedicated extension ladder has reasonable design, light weight, is simple to operate, is convenient to use, is safe and reliable, reduces the labor intensity of overhauling operating personnel, enhances safety factors of operation, only needs to be operated by a person and increases the working efficiency.
Description
Technical field
The utility model relates to a kind of extension ladder, is specifically related to the special-purpose extension ladder of a kind of replacing insulator.
Background technology
In aerial high-voltage power transmission line, composite insulator one of the member that is absolutely necessary.For the installation of composite insulator, in maintenance or inspection transmission line of electricity process, the way that adopts is to climb up and down along composite insulator usually, steps on because operator's climbing is pedaled, and insulator causes damage easily, influences the safe operation of circuit.Perhaps the staff climbs on the shaft tower, after Chain block, back-up protection rope are in place, ladder is suspended on the cross-arm, and the operating personnel is along working to lead under the ladder.But the ladder that uses in work carrying is inconvenient, and because of insulator specifications and models difference, ladder length can not be regulated again, and versatility is not strong.
The utility model content
The technical problems to be solved in the utility model is to change composite insulator used ladder carrying inconvenience and length can not regulate, and provides a kind of replacing insulator special-purpose extension ladder.
The technical solution of the utility model is: the special-purpose extension ladder of a kind of replacing insulator, comprise suspension hook, anti-electromagnetic induction insulating rod and cleat stanchion unit, the cleat stanchion unit is made up of the ladder pipe, the bottom ladder Guan Yufang electromagnetic induction insulating rod of cleat stanchion unit connects, anti-electromagnetic induction insulating rod is connected with suspension hook, and described cleat stanchion unit is composed in series by at least two different hollow ladder pipes of caliber, and terraced pipe is provided with groove, configuration pedal in the groove, pedal is hinged with the ladder pipe.
Described terraced tube end is provided with locked mechanism.
The top ladder pipe of described cleat stanchion unit is provided with and tightens up bandlet and tighten up the ratchet deck.
The number of described terraced pipe is 3～10.
The material of described terraced pipe is an aluminium alloys.
The beneficial effects of the utility model are: the utility model ladder tube end is provided with locked mechanism, and when stretching use, the serial connection of terraced pipe is firm, and extension ladder can be regulated length.Pedal on the ladder pipe is integral structure with the ladder pipe, pedal income groove when the ladder pipe is flexible.The utility model is reasonable in design, in light weight, simple to operate, esy to use, safe and reliable, has alleviated the upkeep operation personnel labor intensity, has strengthened the job safety coefficient, only needs one man operation, has improved efficiency.
