Description
Technical field
The utility model relates to a kind of high-power transformer maintenance and uses quick scaffold.
Background technology
Domesticly newly build up and generally use SF at the large hydropower station of founding a capital
6/ tubing and casing directly links to each other GIS equipment with the main transformer high-pressure side, has both improved equipment dependability, has practiced thrift the valuable device space in hydroelectric power plant again.In case but need carry out test such as winding deformation, D.C. resistance, partial discharge test or GIS loop resistance, switching characteristic after the main transformer overhaul time; Need bushing be connected disconnection so that make an experiment with GIS, treat that recovering the connection side after test finishes can use.Break and draw complicated operation again in (following this operation is called for short to break and draws again) scene; Technological requirement is higher; And the space, power station is compact, is difficult to use high-altitude operation vehicle or on main transformer, reserves permanent inspection platform, could construct so each maintenance needs the scene to set up scaffold.But reasons such as transformer device structure make the scaffold construction have following problem: 1, the disconnected construction point below of drawing again is transformer radiator and pipeline, control system etc., and there is cobble on ground, and common fast-assembling scaffold is difficult to use; 2, many main transformers maybe be with a batch difference, or because cause of reform, exists appearance and size, cooling system structure different, can't make the general quick scaffold of a cover, as making separately according to each transformation, the equipment purchase cost is multiplied; Though 3, adopt that steel pipe/bamboo springboard scaffold cost is lower, structure is flexible, have that bearing capacity is limited, the construction period long, easily transformer radiating system or sleeve pipe are caused defectives such as damage.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of high-power transformer maintenance to use quick scaffold for the deficiency that has overcome prior art; It has general, safe, quick, stable properties, can reach the purpose of in same power station, " producing once, standing entirely and use ".
The purpose of the utility model is achieved in that
Quick scaffold is used in a kind of high-power transformer maintenance; Two lower floor supports that distribute about it comprises, lower floor support top, the left and right sides is provided with left and right sides upper layer bracket, is provided with tranverse connecting rod between the upper layer bracket of the left and right sides; Upper layer bracket top, the left and right sides is provided with working platform; Top is provided with guardrail around the working platform, and working platform is provided with a plurality of collar aperture, and described upper layer bracket can be adjusted with vertical direction in the horizontal direction; The horizontal direction adjustment is used to make each parts of scaffold to avoid radiator and pipeline thereof, and the vertical direction adjustment is used to make the scaffold height freely to adjust according to bushing and GIS structure difference.
Above-mentioned lower floor support bottom, the left and right sides is that leg is regulated, and is used to regulate lower floor support level and locking.
Above-mentioned working platform top is provided with antiskid plate.
Above-mentioned collar aperture inwall is provided with flexible material layer.
Above-mentioned flexible material layer is a rubber tile.
Technique effect below the utility model has been obtained:
1. the utility model has overcome the drawbacks of the special-purpose scaffold fast of the use of large-scale power station main transformer maintenance in the past or steel pipe/springboard scaffold; The different structure main transformer maintenance construction that can be each power station provides a cover flexible, safe, stable working space; It is quick and convenient to set up dismounting, has practiced thrift cost again; The employing aluminum alloy material is made; Have light, high-strength characteristics, significantly reduced to take and torn the possibility of in the scaffold process transformer radiating system, neutral bushing and instrument being damaged open, improved operating efficiency; Guaranteed work quality, be fit to very much electrical production and use.
