Abstract
The utility model discloses a maintenance ladder for a high-voltage isolator, which comprises a vertical ladder and a base. An upper clamping plate is articulated with a lower clamping plate by bolts, and the upper clamping plate and the lower clamping plate are correspondingly provided with openings used for clamping the clamping plates on a channel steel of the base of the isolator by bolts; the vertical ladder is welded on the upper clamping plate; one end of an oblique supporting bar is articulated with a cross bar of the vertical ladder; and a clamping seat is welded on the outer end of the oblique supporting bar and provided with a horizontal bayonet the top of which is screwed with a fastening bolt. The maintenance ladder has the advantages of safety and reliability, simple operation and convenient use, and can effectively reduce labor intensity of operators, improve working efficiency and ensure safe construction.
Description
Technical field
The utility model relates to the maintenance ladder of ascending a height, especially the ladder technical field of high voltage isolator maintenance usefulness.
Background technology
In the maintenance of GW7 type high voltage isolator, the staff uses the common equipment of ascending a height, and the climbing porcelain vase can cause danger.For example, often use the cat ladder maintenance of ascending a height, cat ladder abuts against on the isolating switch base seat groove steelframe so that certain inclination angle is oblique, and with the pedestal relation of forming a fixed connection, existence is not rocked, and the danger that may topple over is unfavorable for safety work.
The utility model content
The purpose of this utility model provides a kind of high voltage isolator esy to use, safe and reliable maintenance ladder.
This novel purpose is achieved in that a kind of high voltage isolator maintenance ladder, comprise cat ladder, also have base: train wheel bridge is hinged through bolt and lower plate, and equal correspondence is provided with and is used to use bolt with the perforate of its clamping on isolating switch pedestal channel-section steel on the upper and lower clamping plate; Cat ladder is welded on the train wheel bridge; The cross bar of inclined support bar one end and cat ladder is hinged; Be welded with a deck on the inclined support bar outer end, a horizontal bayonet socket is arranged on the deck, bayonet socket is connected with a trip bolt on the top.
When the high voltage isolator maintenance is used, upper and lower clamping plate employing with base earlier is bolted on the isolating switch base seat groove steelframe, bayonet socket with oblique support bar outer end deck is stuck on the channel-section steel frame (lateral edges) again, and adopt trip bolt (M12) and channel-section steel frame to fix, after installing, cat ladder, base, inclined support bar three parts form (right angle) triangular support structure, and are reliable and stable.
This novel beneficial effect is:
GW7 type high voltage isolator maintenance ladder, be applicable to the service work of high pressure isolating switches such as 220kVGW7 type, have advantages such as safe and reliable, simple to operate, easy to use, can effectively alleviate operating personnel's labour intensity, increase work efficiency, the staff stand in the maintenance ladder and goes up work, has prevented that effectively the fracture suddenly of disconnecting link porcelain vase is to maintainer's injury.
Description of drawings
Fig. 1 is this novel stereogram;
Fig. 2 is the stereogram of shown in Figure 1 novel another view directions.
Embodiment
Fig. 1 Fig. 2 illustrates, and this novel cat ladder 10 that comprises also has base: train wheel bridge 201 is hinged through bolt 203 and lower plate 202, and equal correspondence is provided with and is used to use bolt with perforate 201a, the 202a of its clamping on isolating switch pedestal channel-section steel on the upper and lower clamping plate; Cat ladder 10 is welded on the train wheel bridge 201; The cross bar 101 of inclined support bar 30 1 ends and cat ladder 10 is hinged; Be welded with a deck 302 on the inclined support bar outer end, a horizontal bayonet socket is arranged on the deck, bayonet socket is connected with a trip bolt 302a on the top.Cat ladder 10 is vertical with train wheel bridge 201.It is hinged that inclined support bar 30 1 ends are welded with a sleeve 301, sleeve and cat ladder 10 cross bars 101; Be fixedly connected with two card stake 201b on train wheel bridge 201 bottom surfaces.Two card stakes are symmetrical arranged on the train wheel bridge bottom surface.When this maintenance ladder was installed, two card stakes can be connected between two parallel channel-section steels, to improve mounting stability.
Design principle: the design principle that GW7 type isolating switch overhauls special-purpose ladder is exactly to utilize the form of footing foundation channel-section steel, sets up two fixing points in the maintenance ladder bottom that makes: feet (being inclined support bar) assembling and supporting leg assembling.Utilize and the fulcrum formation triangle fixed support system of supporting leg on the maintenance special-purpose ladder at these 2, thereby reach secure fixation maintenance special-purpose ladder, the effect of easy access.
The fixed form of feet assembling: utilize the form of footing foundation channel-section steel, live two relative seamed edges of upper side of basic channel-section steel with the rectangular bar of steel plate holder of 2 thickness 12mm, and between two block plates, tighten, reach fixation with the M16 bolt.
This overhauls terraced load: 100kg, and deadweight 20kg forms (seeing picture) by three parts such as base, cat ladder, inclined support bars.This is installed, and to overhaul terraced step very simple, only needs two scalable clamping plate of base are fixed on the GW7 type isolating switch pedestal channel-section steel, is equipped with inclined support bar and is fixedly clamped.
GW7 type high voltage isolator maintenance ladder is mainly used in maintenance, the debugging work of high pressure isolating switches such as 220kVGW7 type.
This maintenance ladder meets electric industry department forbids to climb this kind of disconnecting link porcelain vase in service work regulation, for finishing the work of safety, high-quality provides guarantee.
