Abstract
The utility model provides a crawling ladder for a transformer. The crawling ladder comprises a crawling ladder body mounted on the wall of a transformer tank; an included angle alpha between a vertical center line of the upper part of the crawling ladder body and a vertical center line of the transformer is set in the range from 5 to 11 degrees, so that a maintainer can go up and down by inclining the body instead of going up and down straight; for going down from the ladder, the maintainer has wide vision, and therefore, the maintainer can go up and down easily, and the safety of going up and down is guaranteed.
Description
Technical field
The utility model relates to a kind of cat ladder, especially a kind of cat ladder for transformer.
Background technology
Transformer is as large-scale power device, particularly to oil immersed power transformer, transformer is being carried out to inspection and maintenance, need maintainer to transformer top end face, therefore the cat ladder for transformer is a kind of important transformer part, at the existing cat ladder for transformer, conventional cat ladder structure is to form with the steel-pipe welding of many different-diameters, with bolt, be fixed on the support plate of tank wall again, because vertical center line and the vertical center line of transformer of cat ladder be arranged in parallel, maintainer need to straight up and down move, effort and dangerous when upper and lower, and fastening bolt is arranged on the support plate of tank wall, also the lifting of inconvenient transformer.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of cat ladder for transformer, therefore makes maintainer laborsaving up and down, has guaranteed safety up and down.
For achieving the above object, the technical scheme that the utility model is taked is: include the cat ladder body being arranged on transformer box wall, the angle α between the vertical center line at the position, top of cat ladder body and the vertical center line of transformer is set to 5-11 °.
Cat ladder body is arranged on transformer box wall, maintainer climbs on transformer by cat ladder body, transformer is overhauled, owing to having designed cat ladder body, make maintainer carry out up and down, no longer carrying out straight up and down in the situation of body inclination, when descending stair, maintainer's broad view, therefore makes maintainer laborsaving up and down, has guaranteed safety up and down.
The utility model has designed, also include baffle plate, support plate and fixed head, cat ladder body is set to include top cat ladder body and bottom cat ladder body, top cat ladder body is set to be connected with bottom cat ladder body, the vertical center line of bottom cat ladder body is set to parallel with the vertical center line of transformer, angle α between the vertical center line of top cat ladder body and the vertical center line of transformer is set to 5-11 °, baffle plate is arranged on the cat ladder body of bottom, fixed head is arranged on the tank wall of transformer and on fixed head, is provided with screwed hole, support plate is set to ︹ type and is provided with open slot, support plate is set to respectively connect with top cat ladder body and bottom cat ladder body, support plate is set to connect with fixed head on the open slot of support plate by bolt.
The utility model has designed, and the position, top of top cat ladder body is set to stretch out transformer box cover and is set to inverted U.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model:
Fig. 2 is the structural representation of support plate 4:
Fig. 3 is the top view of Fig. 2.
The specific embodiment
Fig. 1 is first embodiment of the present utility model, illustrate by reference to the accompanying drawings the present embodiment, include top cat ladder body 1, bottom cat ladder body 2, baffle plate 3, support plate 4 and fixed head 6, top cat ladder body 1 is set to be connected with bottom cat ladder body 2, the vertical center line of bottom cat ladder body 2 is set to parallel with the vertical center line of transformer, angle α between the vertical center line of top cat ladder body 1 and the vertical center line of transformer is set to 5 °, baffle plate 3 is arranged on bottom cat ladder body 2, fixed head 6 is arranged on the tank wall of transformer and is provided with screwed hole on fixed head 6, support plate 4 is set to ︹ type and is provided with open slot, support plate 4 is set to respectively connect with top cat ladder body 1 and bottom cat ladder body 2, support plate 4 is set to connect with fixed head 6 on the open slot of support plate 4 by bolt.
In the present embodiment, the position, top of top cat ladder body 1 is set to stretch out transformer box cover and is set to inverted U.
Top cat ladder body 1 and bottom cat ladder body 2 are arranged on transformer box wall, and maintainer climbs on transformer by top cat ladder body 1 and bottom cat ladder body 2, and transformer is overhauled.
Second embodiment of the present utility model, the angle α between the vertical center line of top cat ladder body 1 and the vertical center line of transformer is set to 11 °.
The 3rd embodiment of the present utility model, the angle α between the vertical center line of top cat ladder body 1 and the vertical center line of transformer is set to 8 °.
The 4th embodiment of the present utility model, the angle α between the vertical center line of top cat ladder body 1 and the vertical center line of transformer is set to 5.4 °.
The utlity model has lower feature:
1, owing to having designed cat ladder body, make maintainer carry out up and down, no longer carrying out straight up and down in the situation of body inclination, therefore when descending stair, maintainer's broad view, makes maintainer laborsaving up and down, has guaranteed safety up and down.
2, owing to having designed support plate 4 and fixed head 6, facilitated the install and adjust of cat ladder body.
3, owing to having designed baffle plate 3, prevent animal climbing, guaranteed transformer security of operation.
In the cat ladder technical field for transformer; Every cat ladder body being arranged on transformer box wall that includes, the angle α between the vertical center line at the position, top of cat ladder body and the vertical center line of transformer is set to the technology contents of 5-11 ° in protection domain of the present utility model.
