specific Embodiment approach

[0047] Such as figure 1 The present invention shows a specific implementation method of a self-unloading boom base driven by nine hydraulic motors, including the following steps:

[0048] 1. Production:

[0049] A. Making the flange: forging the flange base 1 with an overall thickness of 160mm, the inner diameter of the flange base 1 is φ3950mm, and the outer diameter is φ4245mm;

[0050] B. Cylinder body production: use 24mm thick steel plate to make cylinder body 2 with inner diameter of φ3964mm, cylinder height is 1177mm, spot weld cylinder body 2, and spot weld reinforcing ribs on the cylinder body;

[0051] C. Two steel plates with a length of 2000mm, a width of 4000mm and a height of 50mm are pre-assembled and welded and then cut by numerical control to form the first flange 3 with an inner diameter of φ2735mm and an outer diameter of φ3948mm, and process the groove;

[0052] D. Two steel plates with a length of 2100mm, a width of 4000mm, and a height of 40mm are pre-...

Abstract

The invention relates to a manufacturing method of a nine-hydraulic-motor driven self-discharging boom base. The method comprises the steps of manufacturing, machining and mounting. The method has the advantages that the manufacturing is simple, and the working efficiency is raised.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a manufacturing method of a self-unloading boom base driven by nine hydraulic motors. Background technique [0002] The jib of self-unloading equipment is a unique equipment for self-unloading ships. The jib has a dead weight of 250 tons. It can be rotated by 90° on the port side and starboard side by the rotating member, and 18° by the luffing member. At present, the rotating components of similar cranes are mainly realized by a 2-meter rotating bearing and a hydraulic motor installed in the crane body, while the base installed on the hull only needs the flatness of the flange surface to meet the requirements of the crane. Requirements for hanging rotating components. However, the rotating member of the self-unloading boom is realized by a 4.2-meter rotating bearing and 9 hydraulic motors installed in the hull base, and the rotating member is a luffing member and needs to be on the ...
