Double-drum intermediate gear linkage winding type hoisting system

A double-drum linkage winding type hoisting system, wherein the system comprises a first hoisting drum and a second hoisting drum, the first hoisting drum and the second hoisting drum are engaged and linked through engagement structures on outer circumferences of the first hoisting drum and the second hoisting drum or are linked through a linkage intermediate member;

• a first hoisting rope is wound around the first hoisting drum, a second hoisting rope is wound around the second hoisting drum, and the first hoisting rope and the second hoisting rope are not connected with each other,
• wherein the linkage intermediate member comprises a gear set, the gear set consisting of one or more cylindrical gears;
• and wherein the first hoisting drum is provided with teeth engaged with the corresponding cylindrical gear of the gear set on a circumference of at least one of two axial ends of the first hoisting drum, and the second hoisting drum is provided with teeth engaged with the corresponding cylindrical gear of the gear set on a circumference of at least one of two axial ends of the second hoisting drum;
• wherein the two axial ends of the first hoisting drum and the two corresponding axial ends of the second hoisting drum are aligned and linked through the linkage intermediate member;
• the linkage intermediate member comprises at least one linkage base mounted on at least one guide rails allowing for the linkage intermediate member to be movably in and out of a linkage position between the first hoisting drum and the second hoisting drum.
