Detailed Description

The present invention will be further illustrated by the following specific examples, which are carried out on the premise of the technical scheme of the present invention, and it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1 and 2, a winch drum comprises a drum body 1, a left hub 2 arranged at the left end of the drum body 1 and a right hub 3 arranged at the right end of the drum body 1, wherein a rope groove for accommodating a steel wire rope is formed in the drum body 1, the steel wire rope is positioned between the left hub 2 and the right hub 3 and is wound on the drum body 1, a plurality of reinforcing rib plates 6 are respectively arranged on the left hub 2 and the right hub 3, and the reinforcing rib plates 6 can be symmetrically arranged 4 or 6 (the number is reasonably arranged according to needs) around the hubs to increase the overall structural strength of the hubs; the left hub 2 comprises a left sleeve 21, a left baffle 22 and a left connecting plate 23, the right hub 3 comprises a right sleeve 31, a right baffle 32 and a right connecting plate 33, a left wear-resisting plate 24 is arranged on the inner side of the left baffle 22, a right wear-resisting plate 34 is arranged on the inner side of the right baffle 32, the left hub 2 and the right hub 3 are arranged in a mirror image mode and are respectively welded to two ends of the barrel 1, the left connecting plate 23 and the right connecting plate 33 are used for being connected with transmission mechanisms on two sides, two ends of the barrel 1 respectively extend into the left sleeve 21 and the right sleeve 31, when the left hub and the right hub are machined, spot welding is firstly carried out on the joint of the barrel 1 and the left sleeve 21 and the right sleeve 31, full welding is carried out after the position is determined to be correct, the full welding comprises the full welding of the inner end, which extends into the sleeve, of the barrel 1, which is in contact with the outer end of the sleeve, and ensures the connection strength of the barrel 1 and the hub;
