[0002] In the sampling fields of coal, cement, mining, electricity, etc., samples will be stored in sample barrels after sampling, and the sample barrels need to be transported to sample preparation points for sample preparation. During the automatic or manual sampling and transportation process, the sample barrels need to be vertically lifted and transferred between different floors or different elevations.

The hoist drum winds the wire rope to drive the sample barrel up, and the hoist drum releases the wire rope to drive the sample barrel down, so as to drive the sample barrel to reciprocate in the vertical direction and finally complete the transportation work. However, the hoist does not have a matching rope-arranging device during actual operation. The sample barrel will be accompanied by the extension and retraction of the wire rope during the lifting process. After multiple cycles of operation, the wire rope is very easy to be wound around the hoist drum in a disorderly manner, causing the drum to be stuck, and then causing the wire rope to be stuck, affecting the normal operation of the entire lifting device, and the reliability of sample barrel lifting is poor.
