In a specific embodiment, the transformer assembly and disassembly device provided by the utility model includes a lifting member 8, a fixed pulley block and a movable pulley block matched with it. Wherein, the fixed pulley block includes the first fixed pulley 1 and the second movable pulley 5, and the movable pulley block includes the first movable pulley 6 and the second movable pulley 5, generally, the first fixed pulley 1 and the second movable pulley 5, the first movable pulley 6 and the second movable pulley The two movable pulleys 5 are arranged side by side respectively, and the pulleys can be fixed by the support. The lifting member 8 can generally be a stay rope, etc., and the lifting member 8 can be wound out through the fixed pulley block. Of course, in other embodiments, it can also be passed through The movable pulley is wound out, and the movable pulley is provided with a hook for suspending the transformer. Generally, the hook is fixedly connected with the movable pulley or its support, which can be preferably fixed by welding. Of course, in other embodiments, other methods can also be used. Fixed, as long as the same technical effect can be achieved, the specific implementation is not limited.

Wherein, the diameter of the pulley and the diameter of the pulley groove can be calculated according to the weight of the actually lifted transformer.

The transformer assembly and disassembly device provided by the utility model is used to pull the transformer through the cooperation of two fixed pulleys and two movable pulleys, which saves construction costs, reduces labor intensity of workers, and improves work efficiency.

Specifically, one end of the lifting member 8 is fixed to the fixed pulley block, and the other end of the lifting member 8 is wound out through the first movable pulley 6, the first fixed pulley 1, the second movable pulley 5 and the second fixed pulley 2 in sequence.

One end of the lifting member 8 is fixed to the fixed pulley block or its support, and is generally detachably fixedly connected. The other end of the lifting member 8 is wound out along the second fixed pulley 2 through the above-mentioned setting method sequentially. Of course, in other implementations In the example, it can also be wound out through the first fixed pulley 1, or one end of the lifting member 8 can be fixed with the movable pulley block, and the other end can be wound out through the movable pulley block, but the position of the extended end of this arrangement is not fixed and inconvenient Force application can be set according to actual conditions during specific operations, all within the scope of protection of the present utility model.

Further, it also includes a third fixed pulley 4 arranged on the bottom of the electric pile 3, and the lifting member 8 is connected with the power member 7 through the third fixed pulley 4 to change the direction of traction.

In order to change the direction of the traction easily, so that the transformer can be pulled by the power part 7, a third fixed pulley 4 can be arranged on the bottom of the electric pile 3, one end of the third fixed pulley 4 is fixed with the electric pile 3, and the other end is connected with the lifting pole 3. The protruding end of the part 8 cooperates to change the direction of the pulling part 8 and reduce the stress on the electric pile 3.

Specifically, the lifting member 8 is a steel wire rope. The diameter of the wire rope can be set according to the needs of the operation. Generally, it is based on the weight of the transformer, such as an 80kVA transformer with a weight of 600kg. You can choose a wire rope with a diameter of 6.2mm. *600=174kg, which meets the weight requirement of the transformer. This is only a preferred implementation. In other embodiments, the specific form and size of the lifting member 8 can be selected according to actual needs, all within the protection scope of the present invention.

It can be understood that the diameter of the pulley can be selected according to the weight of the transformer to be lifted, by the formula D=(e-1)d,

Among them, D - pulley diameter mm

d - wire rope diameter mm

e——Proportional coefficient, lifting block e=11~12, D=(11-1)*6.2=62mm;

Use the formula D0=(d+0.4)～(d+0.8) to calculate the pulley groove diameter:

D0＝(6.2+0.4)～(6.2+0.8)＝6.6～7.0(mm)

After calculation, it is determined to select a pulley with a diameter of 70mm and a wheel groove diameter of 7.0mm, with a bearing capacity of 2.5 tons, which meets the lifting requirements.
