Abstract
The utility model relates to a special ladder for maintenance of 220kV bushings of transformers. The special ladder comprises a ladder, and is characterized in that a pair of embedded limiting rods is arranged on the upper portion of the ladder, a fastening strap used for fixing a ceramic petticoat of a bushing is fixed into hook holes at ends of the limiting rods by tying devices, limiting pins which are spliced with bottom ends of support barrels of the ladder are disposed at the bottom ends of the support barrels of the ladder, and fixing holes matched with flange fixing bolts for mounting the bushing of a transformer are arranged on mounting bottom plates of the limiting pins. The special ladder provides a safe climbing channel for a maintainer to maintain the upper portion of the bushing during maintenance of the 220kV bushings of the transformers, the problem that field maintainers fall down from high places is solved, work efficiency is improved, and field safety production is guaranteed.
Description
Technical field
The utility model relates to a kind of transformer 220kV sleeve pipe special ladder.
Background technology
In the Repair of Transformer course of work; The staff need climb to 220kV sleeve pipe top and overhaul, experiment work; Because of receiving the restriction of transformer 220kV sleeve pipe working environment, can't use common cat ladder, so cause the maintainer can only ride the sleeve pipe porcelain patticoat; Free-hand climbing sleeve pipe, production has caused adverse effect to site safety.
The utility model content
The utility model technical problem to be solved provides a kind of safe and reliable, easy to use transformer 220kV sleeve pipe special ladder that is particularly useful for.
The utility model adopts following technical scheme:
The utility model comprises ladder; It is characterized in that described ladder top is provided with a pair of embedded gag lever post; The fastening bandage that is used for fixing the sleeve pipe porcelain patticoat is fixed in the hook hole of said gag lever post end through tightening device; Described ladder props up a bottom and is provided with ladder and props up the spacer pin that a bottom plugs, and the installation base plate of described spacer pin is provided with and the suitable fixing hole of bushing shell for transformer mounting flange set bolt.
The good effect of the utility model is following:
When the utility model carries out service work at power transformer 220kV sleeve pipe place,, solved the problem of falling in the field service personnel high-altitude, improved operating efficiency, guaranteed site safety production for the maintainer on sleeve pipe top provides safe climbing passage.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Shown in accompanying drawing 1; The utility model comprises ladder 1; It is characterized in that described ladder 1 top is provided with a pair of embedded gag lever post 2; The fastening bandage 4 that is used for fixing the sleeve pipe porcelain patticoat is fixed in the hook hole of said gag lever post 2 ends through tightening device 3, and described ladder 1 bottom is provided with and the ladder 1 bottom spacer pin 5 of hinge mutually, and described spacer pin 5 is provided with and the suitable fixing hole 6 of bushing shell for transformer mounting flange set bolt.
The utility model ladder 1 is processed by epoxide resin material, meets electric power safety related request, and has enough mechanical strengths.Cat ladder crosspiece width is suitable, and anti-skidding line is arranged, and satisfies maintainer's instructions for use.Ladder 1 top is fixed with fastening bandage 4 through embedded gag lever post 2.Fastening bandage 4 has certain bending length, can closely embed the porcelain patticoat crevice place when it is contacted with the sleeve pipe porcelain patticoat, cooperates the use of fastening bandage 4, can ladder 1 top be securely fixed on the bushing shell for transformer, has prevented the damage of sleeve pipe porcelain patticoat simultaneously.Embedded gag lever post 2 is equipped with fastening bandage 4 junctions tightens device 3, can tighten fastening bandage 4.A tube bottom of ladder 1 is a hollow structure, and special-purpose spacer pin 5 is connected.
Spacer pin 5 is processed for metal material, and the upper end is inserted ladder and propped up tube 1 bottom, and the other end can be connected with bushing shell for transformer mounting flange set bolt, and can multi-angle adjust.
The fastening bandage 4 at ladder 1 top is used with the spacer pin 5 of ladder 1 bottom, and cat ladder is fixed on the bushing shell for transformer so that bikini is well-set, satisfies maintainer's instructions for use.
