Abstract
The utility model relates to a framework cat ladder for transformer substation including the fixed terraced pole of upper and lower section that links to each other, is provided with staggered arrangement's step in the upper and lower terraced pole both sides of section, has installed upper and lower connecting plate respectively at the terraced pole of upper and lower section middle part, and the socket is offered to upper segment ladder pole upper end, and insert in the socket pole head lower part to fix a position through pole head locking bolt, the overhead portion of pole is the arc pole, and the lower part is the straight -bar, offers the step jack for to peg graft with the step on the straight -bar. Owing to carry out above -mentioned scheme, adjustment column cap height that this application can be convenient to satisfy the not user demand of co -altitude, and can install the step fast additional, make things convenient for the maintainer to ascend a height.
Description
Technical field
The utility model relates to a kind of framework cat ladder for transformer station.
Background technology
Foreign & Domestic Substations framework adopts steel pipe herringbone bar comparatively general. Require according to 0101020100-1 framework steel cat ladder termination full-page proof in " State Grid Corporation of China's project of transmitting and converting electricity standard technology (six) ": " termination, steel cat ladder top arranges elbow; and elbow exceeds column cap steel plate 700mm ", this way can be better the service of O&M unit, facilitate to fortune inspection personnel, meet safety in production requirement, can provide convenient for daily operation and maintenance. But the column cap of steel pipe inverted Y-shaped column, steel tubular beam framework is comparatively complicated, and hanging wire point absolute altitude and back absolute altitude exist the discrepancy in elevation of half beam section, as still pressed the construction of standard technology way, termination exceeds back will not meet 700mm.
Summary of the invention
The purpose of this utility model is to propose one and prevents cat ladder height deficiency, the framework cat ladder for transformer station of making troubles to the safety inspection of transformer station.
The purpose of this utility model is achieved in that for the framework cat ladder of transformer station and comprises the upper and lower section of terraced bar being fixedly linked, be provided with staggered step upper and lower section of terraced bar both sides, be equiped with respectively upper and lower connecting plate at upper and lower section of terraced bar middle part, socket is offered in epimere ladder bar upper end, insert in socket bar head bottom, and by bar head lock(ing) bolt location, described bar head top is bow, bottom is straight-bar, on straight-bar, offer in order to step peg graft step jack.
Owing to carrying out such scheme, the application is adjustment column grease head highness easily, to meet the user demand of differing heights, and can install fast step additional, facilitates maintainer to ascend a height.
Brief description of the drawings: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is the structural representation for the framework cat ladder of transformer station.
Legend: 1, bar head, 2, epimere ladder bar, 3, step, 31, end bar, 32, cross bar, 4, hypomere ladder bar, 5, lower connecting plate, 6, upper junction plate, 61, expansion plate, 62, lock(ing) bolt, 63, fixed head, 7, bar head lock(ing) bolt, 8, step jack.
Detailed description of the invention: the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, framework cat ladder for transformer station comprises the upper and lower section of terraced bar 2,4 being fixedly linked, be provided with staggered step 3 upper and lower section of terraced bar 2,4 both sides, be equiped with respectively upper and lower connecting plate 6,5 at upper and lower section of terraced bar 2,4 middle parts, socket is offered in epimere ladder bar 2 upper ends, insert in socket bar head 1 bottom, and locate by bar head lock(ing) bolt 7.
Described step 3 comprises and horizontal cross bar 32 upper or that the terraced bar 2 or 4 of hypomere is connected, is provided with the end bar 31 being upturned in cross bar 32 outer ends, and end bar 31 is in order to stop that climbing personnel foot skids off cross bar 32, ensures climbing personnel's safety.
Described bar head 1 top is bow, and bottom is straight-bar, offers the step jack 8 in order to peg graft with step 3 on straight-bar, when climbing personnel step on to higher level's step 3, can hold bow and keep one's balance.
Described upper and lower connecting plate 6,5 structures are identical, and it includes and fixed head 63 upper or that the terraced bar 2 or 4 of hypomere is fixedly linked, is plugged with expansion plate 61 in fixed head 63, are provided with the lock(ing) bolt 62 in order to location at fixed head 63 and expansion plate 61 splicing positions. Expansion plate 61 outer ends with treat that climbing equipment is fixedly linked, thereby by the application entirety location.
The application's entirety is installed at equipment side by upper and lower connecting plate 6,5, and wherein epimere ladder bar 2 arranges perpendicular to ground, and hypomere ladder bar 4 favours ground and arranges, and between epimere ladder bar 2 and hypomere ladder bar 4, angle is not more than 135 degree. When the climbing personnel that are arranged so that of this kind of structure are positioned at hypomere ladder bar 2, naturally rely on epimere ladder bar 2 above the waist, center of gravity remains on the both legs place that health is lower, ensures climbing personnel's safety.
Above technical characterictic has formed most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic.
