Embodiment Construction

[0030] See attached Figure 1-3 As shown, a ship lift nut column installation auxiliary adjustment method includes the following steps:

[0031] 1) Weld the first section steel tooling 4 on the second-stage embedded part 2 at the bottom of the nut column;

[0032] 2) Arrange the bottom jack 5 on the first section steel tooling;

[0033] 3) Hoist and lower the nut column 1 onto the bottom jack;

[0034] 4) Weld 4 sets of second-shaped steel tooling 3 on the position of the second-stage embedded parts corresponding to the four corners of the nut column;

[0035] 5) Arrange lateral jacks 8 between 4 sets of second-shaped steel tooling 3 and nut columns;

[0036] 6) Arrange the 16 sets of process screw rods 6 through the nut columns and the bolt holes on the panel of the second-stage embedded parts;

[0037] 7) Complete the positioning of a pair of 2-piece nut columns through the above steps;

[0038] 8) Arrange the measuring tooling 7 on the top of the two nut columns;

Abstract

The invention relates to a ship lift nut column installation auxiliary adjustment method which is characterized by comprising the steps of (1) welding a first section steel tooling on second phase embedded parts at the bottoms of nut columns; (2) arranging bottom jacks on the first section steel tooling; (3) hanging the nut columns and putting the nut columns onto the bottom jacks; (4) welding four second section steel toolings on the second phase embedded parts corresponding to the four corners of the nut columns; (5) arranging side jacks between the four second section steel toolings and the nut columns; (6) arranging sixteen groups of technical screw rods by the nut columns and bolt holes arranged on panels of the second phase embedded parts; and (7) locating the two nut columns. The ship lift nut column installation auxiliary adjustment method has the advantages of being simple in structure and convenient in processing and manufacturing, realizing on-site installation and disassembly of the toolings and the technical screw rods, being convenient and fast to use and recycle, meeting the installation demands, solving all construction difficulties, being economical, high in quality and efficient, etc.

Description

technical field [0001] The invention provides an auxiliary adjustment method for the nut column installation of a ship lift, which is suitable for the ultra-high-precision nut column installation project of various types of rack and pinion climbing vertical ship lifts, and can also be used for similar high-precision metal screws in other engineering fields. The structure and large-scale equipment installation provide extremely useful reference. Background technique [0002] The Three Gorges ship lift is a rack-and-pinion climbing counterbalanced vertical ship lift. It is the first large-scale ship lift driven by a rack and pinion in the world. It is the first scientific research project in the field of ship lifts for hydropower projects at home and abroad. It does not have any experience that can be used for reference in related fields, and is facing many technical difficulties. The installation of the nut column of its main safety locking structure has prominent constructi...
