Description

Technical Field

[0001] The utility model relates to the field of processing of broken line rope groove drums, and more specifically to a processing tool for broken line rope groove drums used in synchronous traction devices. Background Art

[0002] The folded rope groove for synchronous traction device is a rope groove form introduced from abroad that is suitable for multi-layer winding of wire rope. This rope groove remains parallel to the flange end face in most sections of the drum circumference, and only intersects with the flange end face in a very small section, so the rope groove will inevitably bend. The folded rope groove solves the problems of tangled rope and biting rope during the winding process. The folded rope groove makes the winding of the wire rope smooth and the load between each layer is evenly distributed. This technology greatly prolongs the service life of the wire rope, reduces the damage of the wire rope, improves the safety of equipment operation, and reduces the downtime of mechanical equipment due to rope replacement.
