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 and described supporting leg pivotally attached adapter plate, stretches out the outer part of supporting leg on the adapter plate and is provided with and is used for and load ratio bridging switch bonded assembly connecting bore, and two adapter plates on two supporting legs are oppositely arranged; Base upper surface also is hinged with adapter plate towards a side of supporting leg, and the part of protuberate basic unit also is provided with and is used for and load ratio bridging switch bonded assembly connecting bore on the adapter plate.
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 lock bolt on the bracing frame outer wall, the nut of lock bolt is positioned at outside the bracing frame, and the front end of lock bolt 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 bore of described adapter plate is a Long Circle.
The utility model in use, can be earlier the securing cover plate of voltage transformer M type load ratio bridging switch be connected on supporting leg and the base by adapter plate, concrete steps are: dismounting earlier is a bolt of load ratio bridging switch down, then can pass through this bolt hole and connecting bore 14 bolted connections.Inner core with M type load ratio bridging switch links to each other with suspension hook then, rotates the inner core that lifter can conveniently lift by crane M type load ratio bridging switch.Suspension rod can rotate in bracing frame, tighten lock bolt after, then the friction force between lock bolt 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 adapter plate 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.The beneficial effects of the utility model are: in light weight, compact conformation, just with carry, easy to adjust, maintenance is few, is the special-purpose hoisting device of on-load tap changers of transformers, with use crane to compare to have reduced cost, compared, improved work efficiency and safety with the manpower construction.
