Abstract
This invention relates to a folded compound insulator special rack characterizing that connection rack tubes are connected flexibly by a connection shaft and are folded, the bottom of the tube is connected with an anti-magnetic induction insulation bar, which is connected with a hook made of flat steel, a kick set on the tube is designed to an unified structure with the shaft and is hidden in the tube when being folded, a clip seat is set on the upper part of the tube for fastening the bandlet and ratchet and the connection tubes are made of Al alloy tubes.
Description
Technical field
The invention belongs to the electric power apparatus examination facility, relate to a kind of 66-500kv of being applicable to transmission line synthetic insulator when maintenance string special ladder up and down that dangles, particularly a kind of Foldable synthetic insulator special ladder.
Background technology
Along with the quickening of power grid construction, in order to improve the safe and reliable of electrical network, reduce the time of repair apparatus in recent years, transmission line has been used a large amount of synthetic insulators.At present, domestic when the maintenance circuit, traditional method is that synthetic insulator carries out operation about adopting rope ladder, and very dangerous up and down when the maintainer works, rope ladder ascend operation security performance is relatively poor, working strength of workers big, inefficiency.The hard terraced operation of employing that also has, is used all very inconveniently at hard ladder carrying during operation, and labour intensity is big, inefficiency, security performance are relatively poor.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence, purpose is in order to improve the safety operation level of electric power enterprise, the repair quality of raising equipment, guarantee the maintainer safely, alleviate working strength of workers, increase work efficiency, up and down Foldable synthetic insulator special ladder when providing a kind of 66-500kv of being applicable to transmission line synthetic insulator to dangle the string maintenance.
Foldable synthetic insulator special ladder content Description of the present invention:
Foldable synthetic insulator special ladder of the present invention, it is characterized in that: be by suspension hook, anti-electromagnetic induction insulating rod, pedal, connect the ladder pipe, tighten up bandlet, tighten up the ratchet deck, connecting axle is formed, connecting terraced pipe flexibly connects by connecting axle, be connected with anti-electromagnetic induction insulating rod in the lower end that connects terraced pipe, anti-electromagnetic induction insulating rod is connected with the suspension hook that adopts band steel to make, the pedal that is provided with on the terraced pipe of connection is designed to integral structure with axle, be provided with groove in the junction that connects ladder pipe tube head, folding back foot enters in the groove, pedal is ensconced in the terraced pipe of connection, be provided with on the top that connects terraced pipe and tighten up bandlet and tighten up the ratchet deck.
Connecting the ladder pipe adopts aluminium-alloy pipe to make.
Foldable synthetic insulator special ladder of the present invention, it is a kind of 66-500kv of being applicable to transmission line, when overhauling transmission facility, the maintainer prevents to climb the synthetic insulator string that dangles, avoid causing synthetic insulator to damage, make the indispensable instrument of maintenance of electrical network generation flashover fault, have characteristics reasonable in design, in light weight, simple to operate, esy to use, safe and reliable.Alleviate the upkeep operation personnel labor intensity, strengthened the job safety coefficient, only needed one man operation to improve efficiency.
Description of drawings
