Description of the embodiments
According to the embodiment of the application, by providing the dismounting tool for the horizontal shaft bushing of the cone crusher, the problem that the bushing of the horizontal shaft of the cone crusher is in static fit with the inner hole of the shaft bracket is effectively solved, the win-win amount is large, and the mounting is carried out by cooling with dry ice or liquid nitrogen. When the bushing is dismounted, dry ice is usually used for cooling for a period of time and then dismounted, but the bushing is often dismounted after being cooled and still cannot be dismounted after being cooled due to larger win-win amount, and the bushing is cut by a cutting machine according to the recommended mode of a maintenance manual and then is taken out. The horizontal shaft bushing of the cone crusher is detached by using dry ice for cooling, so that the time consumption is long and the cost is high; when the cutting machine is used for cutting and disassembling, the operation difficulty is high and a certain safety risk exists due to the narrow operation space.
