Abstract
The utility model relates to a kind of high-power transformer casings to overhaul ladder, ladder upper end is equipped with the stabilizing bracket parallel with ladder, steel body joint by the way that radian is adjusted is connect with two symmetrical curved poles, curved pole concave surface is equipped with non-slip mat, and the curved pole rear installing spooler in side is simultaneously connected with restraint zone；The curved pole rear installing in the other side links up with the link matched with restraint zone outer end, and ladder bottom end is connected with oscillating bearing and is connected with feet channel steel.The design of the utility model structure realizes two point form of the ladder on bushing shell for transformer and fixes, and solves the difficulty of high-power transformer casing maintenance climbing, improves work efficiency, ensure that personnel safety.
Description
Technical field
The utility model relates to a kind of ladder, especially a kind of high-power transformer casing overhauls ladder.
Background technique
Transformer is power equipment important in power grid, especially voltage levels transformer, to guarantee its operational safety,
It must be detected at regular intervals, but when removing the bushing lead connecting test line of high-power transformer, by
In on the pure porcelain casing tube that staff need to manually climb about three meters of inclined height or more, need to step down on casing porcelain patticoat during climbing
It works, because underfooting forced area is limited, this brings great security risk and working strength to staff, according to statistics
Remove lead, the time-consuming of connecting test line accounted for 40% of total testing time or more, in addition because of cannula structure shape the features such as,
Common insulating ladder can not be firm be fixed on casing, cause common ladder that can not apply, although using engineering crane scheme
It is feasible, but capital expenditure is serious, and in emergency processing transformer fault, it is interim to call the engineering crane time longer, it is difficult to full
Foot quickly judgement, the requirement of processing transformer fault, and then influence the timeliness of power supply.
Summary of the invention
The utility model overcomes the deficiency of background technique, provides a kind of safe and reliable, enables service personnel quickly up and down
Climb the insulating ladder of bushing shell for transformer.
The utility model adopts the following technical solution: a kind of high-power transformer casing maintenance ladder, which is characterized in that ladder
Upper end is equipped with the stabilizing bracket parallel with ladder, and the steel body joint by the way that radian is adjusted connects with two symmetrical curved poles
It connects, curved pole concave surface is equipped with non-slip mat, and the curved pole rear installing spooler in side is simultaneously connected with restraint zone；Another lateral curvature
The installing of shape pole rear and the link that matches of restraint zone outer end hook, ladder bottom end be connected with oscillating bearing and with feet channel steel phase
Even.
Curved pole possesses certain angular adjustment nargin by the connection of steel body joint.
Foot channel steel is connect with terraced body by oscillating bearing, and distance adjusts between realizing two feet channel steels, satisfaction and different type
The connection of high-power transformer casing flange disk.
It is provided on feet channel steel after multiple adjusting holes are connect with oscillating bearing and ladder body Slope angle adjustment can be achieved.
The utility model has the advantages of as follows:
Terraced body uses glass steel material, meets the safety requirements of application in substations, while avoiding wire ladder to insulator
Collide bring damage；Spooler adjustment binding strip length is installed, binds upper ladder body firmly on insulator；Feet channel steel
Fixed point can be adjusted according to the difference of high-power transformer casing flange disk bolt location, meet the fixed stabilization in terraced body bottom
Property, realizing two point form of the ladder on bushing shell for transformer fixes, solve the difficulty climbed when the maintenance of high-power transformer casing,
It improves work efficiency, ensure that personnel safety；Terraced body can also adjust hole site as desired by feet channel steel and incline to adjust
Gradient；Curved pole can guarantee that curved pole and insulator are in close contact face by steel body joint adjust automatically angle；Terraced body is light
Just, structure is simple, and personnel convenient to overhaul carry.
Detailed description of the invention
It is attached that FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The use of the new type is described further in conjunction with attached drawing:
As shown, a kind of high-power transformer casing overhauls ladder, which is characterized in that ladder 1 uses glass steel material,
Damage insulator is effectively prevent while meeting substation safety requirement, 1 upper end of ladder is equipped with the stabilizing bracket 2 parallel with ladder, leads to
The steel body joint 9 for crossing adjustable-angle is connect with two symmetrical curved poles 3, realizes that curved pole connects with bushing shell for transformer
The adjust automatically of position is touched, curved 3 concave surface of pole is equipped with rubber friction pad 4, and spooler 5 is installed at curved 3 rear of pole in side
And it is connected with restraint zone 6, and restraint zone 6 has certain folding and unfolding nargin；Curved 3 rear of the pole installing in the other side and restraint zone 6
The link matched is linked up in outer end, and 1 bottom end of ladder is connected with oscillating bearing 8 and is connected with feet channel steel 7.
