Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing machinery and equipment, in particular to a motor pulley disassembly device. Background Art

[0002] In the mineral processing industry, sand pumps are used for slurry transportation, powder transportation, and ore crushing and grinding machine sorting. Mineral processing production requires long-term continuous operation of equipment, and the dust concentration in the mineral processing workshop is high and the on-site temperature is high, which can easily cause the motor to burn out. Therefore, the motor needs to be repaired and maintained in time. Removing the pulley on the motor is one of the important links. The commonly used tool is the triangular puller. In the process of using the puller to remove the motor pulley, the pulling claw needs to act directly on the inner end face of the pulley. Since the pulling claw has a small force area and the pulley is rusted and brittle, it is easy to cause the pulley to be "pulled and broken" and damaged. In addition, in order to cooperate with the puller, it is often necessary to manually knock the pulley, which has problems such as high labor intensity, low efficiency, and high safety risks for operators.
