However, during the use of the setting device, the pot insulator and the annular pressure plate must only be hoisted twice. Due to the heavy weight of the pot insulator and the ring pressure plate, the installation process is relatively difficult, and the two hoistings will seriously affect the efficiency. If the upper platen is first installed on the valgus edge of the pot insulator, and the upper platen and the pot insulator are installed on the support base through one hoisting, in order to ensure the coaxiality of the upper platen and the valgus edge of the pot insulator during the hoisting process It is necessary to adjust the radial relative position of the upper platen and the pot insulator. The adjustment process will not only affect the hoisting efficiency but also cause wear to the valgus edge of the pot insulator. Therefore, the above-mentioned setting device is not suitable for completing the upper platen in one hoisting. and pot insulator installation methods.
