Embodiment Construction

[0046] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 9 As shown, a rack and pinion climbing type vertical ship lift nut column efficient installation method, the method consists of the following steps:

[0047] 1) Arrangement of reference points: On the base plate at the bottom of the installation position of the two pieces of nut posts, the positioning reference points of the nut posts are measured and released by measuring the throwing points with high-precision measuring instruments.

[0048] 2) Bottom tooling installation: Bottom auxiliary devices are arranged at the bottom of the second-stage embedded parts 4 of the nut column, and the bottom auxiliary devices are bottom-shaped steel structure tooling 7 equipped with jacks 14 .

[0049] 3) Hoisting of two pieces of nut columns: After hoisting the two pieces of nut columns in place, temporarily reinforce the nut columns through the bottom auxiliary device, forward auxiliary device and side auxiliary d...

Abstract

The invention provides an efficient installation method for nut columns of a gear and rack climbing-type vertical ship lift. The method comprises the following steps: (1) arranging datum points; (2) installing a work fixture at the bottom; (3) hoisting the two nut columns; (4) welding a coil holder; (5) hanging a vertical line; (6) adjusting and reinforcing the elevation direction of the first nut column; (7) adjusting and reinforcing the side direction of the first nut column; (8) adjusting and reinforcing the forward direction of the first nut column; (9) adjusting and reinforcing the elevation direction, the side direction and the forward direction of the second nut column; (10) erecting a formwork; (11) installing prestressed reinforcing bars; (12) grouting intervals; (13) stretching the prestressed reinforcing bars; and (14) checking and accepting the final installation quality, thus completing the efficient installation of the nut columns of the gear and rack climbing-type vertical ship lift. The invention also provides an auxiliary device for installation. The efficient installation method for the nut columns of the gear and rack climbing-type vertical ship lift and the auxiliary device, provided by the invention, realize the rapid high-quality installation of the nut columns of the gear and rack climbing-type vertical ship lift.

Description

technical field [0001] The invention relates to a high-efficiency installation method and auxiliary device for parts of a ship lift, in particular to an efficient installation method and an auxiliary device suitable for the installation project of ultra-high-precision nut columns of various types of rack and pinion climbing vertical ship lifts. Background technique [0002] The Three Gorges large-scale rack and pinion vertical ship lift project, as the first scientific research project in the field of ship lifts for hydropower projects at home and abroad, is facing many technical problems, and there is no experience that can be used for reference in related fields. Nut column installation project has outstanding construction difficulties such as large single-piece size and weight, complex structure, high installation height, high technical difficulty, and extremely high installation quality requirements. It is necessary to innovate and develop appropriate installation technol...
