Referring to Fig. 1, Fig. 1 is a kind of structural representation of transformer assembling and disassembling device provided in an embodiment of the present invention.
In a kind of specific embodiment, the transformer assembling and disassembling device that the present invention is provided, including lifting piece 8, fixed pulley
Group and the running block coordinated with it.Wherein, fixed pulley group includes the first fixed pulley 1 and the second movable pulley 5, and running block includes
First movable pulley 6 and the second movable pulley 5, it is general, between the first fixed pulley 1 and the second movable pulley 5, the first movable pulley 6 and second
It is set up in parallel, pulley can be fixed by bearing respectively between movable pulley 5, lifting piece 8 can be typically drawstring etc., lifting piece
8 can be laid out by fixed pulley group, certainly, in other embodiments, can also be laid out by running block, be set on running block
Hook for hanging transformer, general, hook is fixedly connected with running block or its bearing, preferably to be welded and fixed,
Certainly, in other embodiments, it can also be fixed by other means, as long as identical technique effect can be reached i.e.
Can, concrete implementation mode is not construed as limiting.
Wherein, the diameter of the diameter of pulley and pulley groove can be calculated according to the weight of the transformer of actual lifting
Arrive.
The transformer assembling and disassembling device provided using the present invention, by the cooperation of two fixed pulleys and two movable pulleys, to becoming
Depressor is drawn, and it saves construction cost, reduces intensity of workers, improves operating efficiency.
Specifically, one end of lifting piece 8 is fixed with fixed pulley group, the other end of lifting piece 8 successively through the first movable pulley 6,
First fixed pulley 1, the second movable pulley 5 and the second fixed pulley 2 are laid out.
One end of lifting piece 8 is fixed with fixed pulley group or its bearing, is generally removably fixedly connected, lifting piece 8
The other end is laid out through above-mentioned set-up mode along the second fixed pulley 2 successively, certainly, in other embodiments, can also pass through
One fixed pulley 1 is laid out, or, one end of lifting piece 8 and running block can be fixed, the other end is laid out by running block, but
The position of such a set-up mode external part is not fixed and inconvenience force, in specific operation, can be carried out according to actual situation
Set, within the scope of the present invention.
Further, in addition to the 3rd fixed pulley 4 on the electric bottom of stake 3, lifting piece 8 through the 3rd fixed pulley 4 with it is dynamic
Power part 7 connects to change traction force direction.
, can be at the electric bottom of stake 3 in order to be lifted by force piece 7 to transformer for the ease of changing traction force direction
3rd fixed pulley 4 is set in portion, and one end of the 3rd fixed pulley 4 is fixed with electric stake 3, and the external part of the other end and lifting piece 8 coordinates,
To change the direction of lifting piece 8, stress suffered by electric stake 3 is reduced.
Specifically, lifting piece 8 is steel wire rope.The diameter of steel wire rope can be configured according to job requirements, general basis
The weight of transformer, such as 80kVA transformers, weight is 600kg, and the steel wire rope of 6.2mm diameters may be selected, and its destruction pulling force is
24kN, it is allowed to which pulling force is 3kN, pulling force suffered by steel wire rope is 0.29*600=174kg, meets transformer weight requirements, herein only
For preferred embodiment, in other embodiments, the concrete form and dimensions of lifting piece 8 can be selected according to actual needs,
It is within the scope of the present invention.
It is understood that the diameter of pulley can be selected according to the weight for treating lifting transformer, pass through formula D=
(e-1) d,
Wherein, D --- diameter of pulley mm
D --- wirerope diameter mm
E --- proportionality coefficient, lifting block e=11~12, D=(11-1) * 6.2=62mm；
Using formula D0=(d+0.4)~(d+0.8), pulley groove diameter is calculated：
D0=(6.2+0.4)~(6.2+0.8)=6.6~7.0 (mm)
Through measuring and calculating, it is determined that from a diameter of 70mm, a diameter of 7.0mm of race pulley, supporting power is 2.5 tons, is met
It is important to ask.
