[0002] With the increase of the rated load of the crane, the pulling force of the wire rope is increasing, and the bearing capacity of the reel of the corresponding crane also needs to be increased. The existing method for increasing the bearing capacity of the reel is to increase the thickness of the cylinder wall of the cylinder, but At present, the thickness of the cylinder wall has reached a certain limit. At present, the steel wire rope with a diameter of 66mm and a rated tensile force of 125t has reached 107mm, and the thickness of the cylinder wall continues to increase. It is difficult to make, which significantly increases the manufacturing cost of the reel

The invention relates to a winding drum. The winding drum comprises a cylindrical drum body for winding a steel wire rope, the drum body comprises an inner layer drum wall, an outer layer drum wall and a connection layer, wherein the outer layer drum wall is arranged on the outer portion of the inner layer drum wall in a sleeving manner, and a predetermined gap exists between the outer layer drumwall and the inner layer drum wall; and the connection layer is located between the inner layer drum wall and the outer layer drum wall, is in fit arrangement with the inner layer drum wall and the outer layer drum wall correspondingly and is a hard material workpiece. By means of the winding drum, the bearing capacity can be improved, and then the lifting capacity of a crane comprising the winding drum is improved, the fabrication difficulty is reduced, and the fabrication cost is saved. The invention further provides the crane.
Description
technical field [0001] The invention relates to the field of cranes, in particular to a drum and a crane. Background technique [0002] With the increase of the rated load of the crane, the pulling force of the wire rope is increasing, and the bearing capacity of the reel of the corresponding crane also needs to be increased. The existing method for increasing the bearing capacity of the reel is to increase the thickness of the cylinder wall of the cylinder, but At present, the thickness of the cylinder wall has reached a certain limit. At present, the steel wire rope with a diameter of 66mm and a rated tensile force of 125t has reached 107mm, and the thickness of the cylinder wall continues to increase. It is difficult to manufacture, which significantly increases the manufacturing cost of the reel. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a reel, including a cylindrical cylinder for windi...
