Method for adjusting the flatness of the large bottom plate of the tower body

Abstract

The invention discloses a method for regulating flatness of a large bottom plate of a tower body, and belongs to the field of marine machinery. The method comprises the following steps: obtaining a plurality of test data and a flatness numerical value by detecting the flatness of the large tower plate of the tower body along a mounting screw hole in the large bottom plate; determining whether the large bottom plate of the tower body needs carrying out flatness regulation according to the flatness numerical value; when the large bottom plate of the tower body needs carrying out flatness regulating, determining a to-be-regulated position on the large bottom plate of the tower body according to the plurality of test data; and additionally arranging a gasket between the to-be-regulated position of the large bottom plate of the tower body and a rotary bearing. According to the method disclosed by the invention, the plurality of the test data and the flatness numerical value are detected along the mounting screw hole in the large bottom plate of the tower body, the to-be-regulated position is determined, and the regulating gasket is additionally arranged on the to-be-regulated position to regulate the flatness of the large bottom plate of the tower body, so that the problem that the large bottom plate of the tower body is uneven is solved, re-processing of the mounting surface of the rotary bearing is avoided, the high production cost is reduced, the low efficiency is improved, and the production period of products is shortened.

Description

technical field [0001] The invention relates to the field of ship machinery, in particular to a method for adjusting the flatness of a large bottom plate of a tower body. Background technique [0002] The marine crane is a common marine cargo handling equipment. Since the marine crane is mainly used to load and unload cargo on the shore and on the ship, it needs to have a slewing system. The slewing system includes the large bottom plate of the tower body, the slewing bearing and the tower body structure. The slewing bearing includes an inner ring and an outer ring that can rotate around the inner ring. The bottom plate is connected so that the large bottom plate of the tower body is rotatably installed on the tower body structure. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] After the large base plate of the tower body is machined, it is connected with the slewing b...

AI Technical Summary

Problems solved by technology

[0004] The large base plate of the tower body is connected to the slewing bearing by bolts after machining, but the installation surface of the slewing bearing is easily deformed due to welding, and the deformation amount and deformation range are difficult to predict. The large base plate is uneven, so it needs to be disassembled and reprocessed on the installation surface of the slewing bearing, resulting in high production cost, low efficiency, and prolonging the production cycle of the product
