[0002] The crane drum rope guide is an accessory for electric hoists. Its main function is to ensure that the wire rope can be neatly arranged on the drum to prevent the electric hoist from malfunctioning due to chaotic overlapping of the wire rope. The rope guide, also known as the rope guide, is generally a combination type and is usually made of ductile iron and other materials. The design and installation of the rope guide is crucial to ensuring the normal operation of the electric hoist and extending its service life.

[0003] Based on the above, the inventors have found that the existing combined drum rope guide has the following deficiencies:

[0004] 1. The rope guide plate and the drum shell of the rope guide are in sliding contact, which leads to a large friction resistance of the rope guide. It is not convenient to add rolling contact measures on the rope guide plate to reduce the friction resistance of the rope guide.

[0005] 2. The internal spiral structure of the rope guide needs to match the spiral structure of the drum, which makes the rope guide unsuitable for drums with different spiral structures, and it is not convenient to replace the spiral structure with an adjustable roller. Utility Model Content
