Description

Technical Field

[0001] The utility model belongs to the technical field of roller disassembly tooling, and in particular relates to a disc pulling tooling used for disassembling a connecting disc at an end of a roller. Background Art

[0002] Belt conveyors are widely used material conveying equipment, and rollers are key components of belt conveyors. The roller structure of a belt conveyor includes an outer skin, with discs connected to both ends of the outer skin, and the discs are supported on the roller shaft through bearings. After the belt conveyor has been running for a certain period of time, the outer skin of the roller will wear and cause damage, so it is necessary to replace a new roller or repair the damaged roller. When repairing the roller, the roller needs to be disassembled and the worn parts need to be replaced. The current method for removing the connecting disc at the end of the roller is to hoist the roller to a press and use the press to press the shaft so that the connecting disc is detached from the roller shaft. Since the roller is very heavy, it is inconvenient to flip it back and forth when operating on the press. Not only is it unsafe during operation, but the disassembly time is long, which greatly reduces work efficiency. Therefore, it is necessary to propose improvements. Utility Model Content
