AI Technical Summary
The fixed position of the upper pulley of the existing hoist makes it difficult to replace the pulley and belt, affecting the operating efficiency of the equipment.
A belt pulley tensioning device for a hoist was designed. The height of the upper belt pulley is precisely adjusted by the cooperation of a screw and double nuts. Combined with an electric push rod and a guide mechanism, the relative position of the upper and lower belt pulleys is kept stable. The adjustment method is flexible and convenient.
It achieves high-precision adjustment of the pulleys, reduces the impact of equipment vibration, improves transmission efficiency, and extends the service life of belts and pulleys.
