Description
Technical field
The present invention relates to hoisting device for on-load tap changers of transformers, especially a kind of M type hoisting device for on-load tap changers.
Background technology
In electric power system, 110kV and above transformer, it is more and more to use on-load tap changer, and on load tap changer has played important function to the rate of qualified voltage that improves electric power system.The maintenance of on load tap changer is also often got up, and the lifting of on load tap changer is mainly contained two ways, and the one, use crane, manually lift in addition, bigger with crane cost, manually lift the unstable switch that damages easily.
Summary of the invention
The purpose of this invention is to provide a kind of in light weight, compact conformation, just with carry, easy to adjust, the transformer M type hoisting device for on-load tap changers that maintenance is few.
For achieving the above object, the present invention adopts following technical scheme: a kind of hoisting device for on-load tap changers of transformers, comprise base, vertically be provided with the suspension rod that has rope on the base, rope one end links to each other with lifter, and the other end links to each other with suspension hook, and described chassis side laterally is provided with supporting leg, supporting leg and base are hinged, and supporting leg is provided with fixed connection apparatus.
Described supporting leg is the tabular of semi-round ring shape, and an end is hinged by rotating shaft and base, and the supporting leg other end is provided with fixed connection apparatus.
Described supporting leg is two.
Described fixed connection apparatus is the fixed head hinged with described supporting leg, stretches out the outer part of supporting leg on the fixed head and is provided with and is used for the connecting hole that is connected with on load tap changer, and two fixed heads on two supporting legs are oppositely arranged; Base upper surface also is hinged with fixed head towards a side of supporting leg, and the part of protuberate basic unit also is provided with and is used for the connecting hole that is connected with on load tap changer on the fixed head.
The high 30-40mm of described base.
Vertically be installed with hollow bracing frame on the base, in the bearing of described boom heel sleeve in bracing frame.
Laterally be equipped with clamping screw on the bracing frame outer wall, the nut of clamping screw is positioned at outside the bracing frame, and the front end of clamping screw and suspension rod outer wall offset.
Be interval with pulley on the described suspension rod, rope is wrapped on the pulley; Lifter is arranged on the suspension rod of bracing frame top.
It is 700mm-800mm that described two supporting legs are oppositely arranged the round diameter that forms.
The connecting hole of described fixed head is a Long Circle.
The present invention in use, can be earlier the securing cover plate of transformer M type on load tap changer be connected on supporting leg and the base by fixed head, concrete steps are: dismounting earlier is a bolt of on load tap changer down, then can be connected with connecting hole 14 bolts by this bolt hole.Inner core with M type on load tap changer links to each other with suspension hook then, rotates the inner core that lifter can conveniently lift by crane M type on load tap changer.Suspension rod can rotate in bracing frame, tighten clamping screw after, then the frictional force between clamping screw and the suspension rod can stop suspension rod to rotate, vice versa.The high 30-40mm of base, the same with loaded switch securing cover plate height, be convenient to fixed head and be connected on the loaded switch securing cover plate bolt.Two semi-circular supporting legs all are that the center can be rotated with the rotating shaft, but then two supporting leg opening and closing are suitable for connecting various model loaded switch cover plates, on the switch securing cover plate bolt.
