[0002] The Chinese patent with publication number CN203156678U discloses a rapid disassembly and installation device for a furnace roller bearing seat, and in particular, relates to a rapid disassembly and installation device for a furnace roller bearing seat of a plate and strip heating furnace. The utility model includes a disassembly device and an installation device for a furnace roller bearing seat. The device adopts a commonly used top screw and pressure plate structure, which is simple in principle and easy to operate. The use process is easy to understand. When disassembling the bearing seat, you only need to use "bolt push", and when installing the bearing seat, you only need to use "pressure plate pressure". The utility model device is made of ordinary steel plates and commonly used bolts through simple processing. It is easy to obtain materials and does not require high technical skills from the operator. The application of this device eliminates the deformation and damage to the body of the bearing seat caused by the original disassembly and assembly methods (hammering, prying).

[0003] As we all know, when the heating roller bearing seat is disassembled, the bearing seat disassembly tool plays an important role, because during the use of the heating roller, due to long-term thermal expansion and contraction, the bearings and bearing seats at both ends of the heating roller will be deformed, making the disassembly of the bearings and bearing seats very difficult. Especially when replacing the bearing seats of a large number of heating rollers, if the original disassembly method is used, it will lead to a long processing cycle, damage to the heating roller, tight construction period, and failure to meet the delivery time and use requirements required by customers.
