Abstract
The main transformer inner detection cambered surface supporting ladder comprises an upper ladder body and a lower ladder body, wherein the upper ladder body and the lower ladder body are detachably connected into a whole; an arc cushion block which is used for contacting with the winding enclosure screen of the transformer is arranged at the upper end of the upper ladder body. The utility model provides a main transformer inner detection cambered surface supporting ladder, which adopts a two-section combined structure, so that the ladder is conveniently transported into a transformer through a manhole and then assembled into the transformer; and be equipped with the arc rubber piece with transformer winding purse seine matched with at the ladder top, can be fine laminate mutually with transformer winding purse seine.
Description
Technical Field
The utility model relates to the technical field of transformer overhaul, in particular to a main transformer inner detection cambered surface supporting ladder.
Background
The internal space of the large main transformer is narrow and very smooth, but the internal inspection of the main transformer needs to check the upper space of the transformer, and for a 500KV transformer, the upper space is about 6 meters away from the bottom of the box, so that a special ladder for the internal inspection of the main transformer needs to be used. However, because the main transformer manhole is limited in size, a herringbone ladder meeting the 6-meter overhaul height cannot be transmitted to the inside of the transformer through the manhole, and because a winding enclosure of the transformer is round and smooth, a traditional ladder is unstable when being lapped on the winding, and the risk of damaging the enclosure is caused.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a main transformer inner detection cambered surface supporting ladder which can be stably erected on a transformer winding.
In order to solve the technical problems, the utility model adopts the following technical scheme: the main transformer inner detection cambered surface supporting ladder comprises an upper ladder body and a lower ladder body, wherein the upper ladder body and the lower ladder body are detachably connected into a whole; an arc cushion block which is used for contacting with the winding enclosure screen of the transformer is arranged at the upper end of the upper ladder body.
Preferably, the lower end of the upper ladder body is provided with a lower threaded part, the upper end of the lower ladder body is provided with an upper threaded part, and the lower threaded part and the upper threaded part are connected into a whole through a sleeve thread.
Preferably, the upper end of the upper ladder body is provided with a cross rod, and the arc cushion block is arranged on one side of the cross rod.
Preferably, the arc-shaped cushion block is made of rubber material, and the radian of the arc-shaped cushion block is consistent with the radian of the surface of the transformer winding enclosure screen.
Preferably, the lower end of the lower ladder body is provided with an anti-skid block.
The utility model provides a main transformer inner detection cambered surface supporting ladder, which adopts a two-section combined structure, so that the ladder is conveniently transported into a transformer through a manhole and then assembled into the transformer; and be equipped with the arc rubber piece with transformer winding purse seine matched with at the ladder top, can be fine laminate mutually with transformer winding purse seine.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is an enlarged schematic view of the structure of the present utility model A;
FIG. 3 is a schematic view of the assembled structure of the present utility model;
fig. 4 is a schematic view of the structure of the present utility model in use.
Detailed Description
As shown in fig. 1-2, the main transformer inner detection cambered surface supporting ladder comprises an upper ladder body 1 and a lower ladder body 2, wherein the upper ladder body 1 and the lower ladder body 2 are detachably connected into a whole; an arc cushion block 3 for contacting with the winding enclosure screen of the transformer is arranged at the upper end of the upper ladder body 1.
Preferably, the lower end of the upper ladder body 1 is provided with a lower threaded portion 4, the upper end of the lower ladder body 2 is provided with an upper threaded portion 5, and the lower threaded portion 4 and the upper threaded portion 5 are integrally connected through a sleeve 6 in a threaded manner.
Preferably, the upper end of the upper ladder body 1 is provided with a cross rod 7, and the arc cushion block 3 is arranged on one side of the cross rod 7.
Preferably, the arc-shaped cushion block 3 is made of rubber material, and the radian of the arc-shaped cushion block is consistent with that of the surface of the transformer winding enclosure screen.
Preferably, the lower end of the lower ladder body 2 is provided with an anti-skid block 8.
When in use, the lower thread part 4 and the upper thread part 5 are respectively sleeved at the upper end and the lower end of the sleeve 6, then the sleeve 6 is rotated, and the lower thread part 4 and the upper thread part 5 are in threaded connection with the sleeve 6, so that the upper ladder body 1 and the lower ladder body 2 are assembled into a whole, as shown in fig. 3. The ladder is then raised again against the outside of the winding as shown in fig. 4.
The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
