A transport pallet 21 for transporting the circuit breaker pole is provided on one side of the base 1, a disassembly bracket 22 for fixing the circuit breaker pole is provided on one side of the transport pallet 21, the disassembly bracket 22 is placed on the surface of the base 1, a moving contact connection tool 23 is placed on the surface of the base 1, a storage tray 25 is provided on one side of the moving contact connection tool 23, and a flange assembly rolling platform 24 is provided between the storage tray 25 and the moving contact connection tool 23.
[0020] Furthermore, if Figure 3 As shown, the flange assembly rolling platform 24 is composed of a flange assembly support frame 241, a flange assembly support platform 242 and a flange assembly support wheel 243. The surface of the base 1 is provided with a flange assembly support frame 241, and flange assembly support wheels 243 are fixed on both sides of the top of the flange assembly support frame 241. The distance between the flange assembly support wheels 243 is greater than the diameter of the moving and static contacts of the pole. Flange assembly support platforms 242 are installed inside the flange assembly support wheel 243 at equal intervals, and the plane where the top of the flange assembly support platform 242 is located is higher than the plane where the top of the flange assembly support wheel 243 is located.
[0021] During use, first place the whole-phase pole on the surface of the transport pallet 21 and transport it to one side of the decomposition bracket 22 through the transport pallet 21, then fix the whole-phase pole on the surface of the decomposition bracket 22, then remove the arc chamber porcelain bottle and the support porcelain bottle, that is, the upper and lower pole connection bolts, and lift the arc chamber porcelain bottle 15CM to remove the insulating pull rod pin connecting the upper and lower poles to disengage the upper and lower poles, fix the arc chamber porcelain bottle of the upper pole part on the surface of the moving contact connection tooling 23, remove the moving and static contact connection bolts, so that the moving and static contacts of the pole are separated, and the upper and lower current channels of the moving and static contacts of the removed pole are respectively placed on the surface of the flange assembly rolling platform 24.

[0024] Then place the whole phase pole on the surface of the transport pallet 21 and transport it to the side of the decomposition bracket 22 through the transport pallet 21, then fix the whole phase pole on the surface of the decomposition bracket 22, then remove the connecting bolts of the arc extinguishing chamber porcelain bottle and the supporting porcelain bottle (i.e. the upper and lower poles) and lift the arc extinguishing chamber porcelain bottle 15CM to remove the insulating pull rod card pin connecting the upper and lower poles to disengage the upper and lower poles, fix the upper pole part (arc extinguishing chamber porcelain bottle) on the surface of the moving contact connection tooling 23, remove the moving and static contact connection bolts to disengage the moving and static contacts of the pole, and place the taken out moving and static contacts of the pole (upper and lower current channels) on the surface of the flange assembly rolling platform 24 respectively, and assemble them on the flange assembly support platform. Under the action of 242, the pole moving and static contacts can be supported and the auxiliary device can be moved. At the same time, since the distance between the flange assembly support wheels 243 is greater than the diameter of the pole moving and static contacts, it is convenient to insert the contacts between the flange assembly support wheels 243 when placing them, and hoist the upper and lower porcelain bottles of the pole onto the storage tray 25, which can complete the disassembly of the entire pole body. It can timely and conveniently solve the problem of factory-based standardized disassembly and assembly of the circuit breaker pole body near the equipment operation.
