specific Embodiment approach

[0022] Such as figure 1 The present invention shows a specific implementation of the installation process of the self-unloading boom base driven by nine hydraulic motors, including the following steps:

[0023] A. Welding: divide the base into upper and lower parts, weld the base in the infield, control the welding deformation, and complete the welding of the upper hull structure 4;

[0024] B. Pre-installation: After the welding of the superstructure hull structure, start to position and install the cylinder body. The flange processing surface of the cylinder body should be protected. In the positioning of the hull structure, a 0.8mm steel wire is used to hang the vertical line to connect the upper base point and the cylinder body. The center line is aligned with the midship line of the hull and the three points are on the same vertical line, with an error of less than 5mm;

[0025] C. Cylinder guy line: Confirm the upper datum point before pulling the wire. The upper datum...

Abstract

The invention relates to an installation process of a self-disassembling suspension arm base driven by nine hydraulic motors. The installation process includes the following steps: welding, pre-installation, barrel wire drawing, barrel installation, machining and hole enlarging on nine motor base holes in flanges. The installation process has the advantages that installation is relatively convenient, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to an installation process 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...
