[0002] During the installation of continuous casting or ESP equipment, when the connecting rod and the fixed support of the ladle turret are threaded through the shaft, the connecting rod and the shaft support need to be threaded together first, and then the bearing end covers on both sides are installed. Due to the limitation of the hoisting space during the hoisting process, only a crane in the workshop can be used to hoist the connecting rod during assembly, and the crane cannot be used to hoist the pin shaft during the threading of the shaft due to limited space. In the past, cantilever steel was welded on the support, and the shaft was hoisted by a hand winch for assembly. This affected the welding of the equipment and the stress on the equipment components. In addition, the surface of the shaft was smooth during hoisting and it was not easy to tie it. It was very dangerous during the assembly process, and it was not easy to find the shaft hole.

[0039] Preferably, after the pin is inserted, the above-mentioned support frame and tray need to be removed, and the pin 12 is sealed and fixed by the shaft end cover 11 to ensure that the pin is stable in the ladle turret.

[0040] Preferably, a connecting rod arm 9 is also provided on the fixed support, and the connecting rod arm 9 is connected to the side shaft hole 8 for hoisting the fixed support, wherein a plurality of side shaft holes are opened on the fixed support to facilitate the connection of support frames and connecting rod arms 9 at various angles.

[0041] A method for installing a connecting device between a connecting rod of a ladle turret and a fixed support pin shaft comprises the following steps:

[0042] Align the support frame, place the pallet on the support frame and fix it, with the pallet carrying the connecting rod;
