Description

Technical Field

[0001] The utility model relates to the field of grinding roller disassembly and assembly auxiliary equipment of a grinding mill, in particular to a grinding roller disassembly and assembly trolley slide rail adjustment structure. Background Art

[0002] The roller disassembly and assembly trolley is a supporting equipment for the mill. It can be raised and lowered to disassemble and assemble the rollers on the mill. The mill has various sizes in the length direction, and the rollers also have various sizes. When the roller disassembly and assembly trolley disassembles the roller, in order to maintain stability, two cantilevers are needed to support the roller. The trolley rises, driving the cantilever to rise, and the roller leaves the installation position, and then the roller is rolled onto the support plate of the trolley. When installing the roller, the roller is rolled from the trolley to the cantilever, and the trolley descends, driving the cantilever to descend, and the roller is installed to the appropriate position. The two cantilevers of the existing roller disassembly and assembly trolley are fixed. In order to meet the disassembly and assembly of rollers of all lengths, the distance between the two cantilevers needs to be less than the shortest roller. During the disassembly or transportation of long rollers, the center of gravity of the roller is easy to deviate from the cantilever and roll over. When installing the roller, the roller disassembly and assembly trolley loaded with the roller needs to be adjusted back and forth to align the center of the roller with the center of the equipment before the roller can be installed to the appropriate position. The trolley carrying the grinding roller is heavy and difficult to adjust back and forth. Utility Model Content
