Embodiment 1

[0044] The embodiment of the present invention provides a vertical alignment tool, the structure of which is as follows Figure 1 to Figure 3 As shown, it includes an upper eye plate 1, a hanging adjustable positioning seat 2, a hollow sliding cylinder 3, a suspension wire 4 and a weight 5. The upper eye plate 1 is used to install and fix the entire vertical alignment tool, and the upper eye plate 1 is set There are eyelets 11. In this embodiment, the vertical alignment tool is used for the construction of ship rudder system equipment, so the upper eye plate 1 is installed on the steering gear cabin of the ship, specifically on the strong structure of the roof in the steering gear cabin, that is, the rudder stock Where the centerline is at the rib. The hanging adjustable positioning seat 2 is suspended and installed on the upper eye plate 1, the hollow sliding cylinder 3 is movably set in the hanging adjustable positioning seat 2, the hanging wire 4 passes through the hollow s...

Embodiment 2

[0051] Based on the same inventive concept, this embodiment provides a method for aligning and hoisting a ship's rudder system, which is implemented based on the vertical aligning tooling of the above-mentioned embodiment 1, and specifically includes the following steps:

[0052] 1. Alignment of ship rudder system:

[0053] 1-1. Determine the upper theoretical point on the steering gear cabin of the ship according to the coordinate size of the upper theoretical point in the layout drawing of the rudder system, and install and fix the upper eye plate 1 according to the upper theoretical point; specifically, the upper eye plate 1 is installed and fixed in the steering gear cabin On the strong structure of the top plate, that is, where the center line of the rudder stock is located.

[0054] 1-2. Install the hanging adjustable positioning seat 2 on the eyelet 11 of the upper eye plate 1 through the clamp assembly 27, and place the hollow sliding cylinder 3 in the adjustment part ...

Abstract

The invention discloses a vertical alignment tool and a ship rudder system alignment and hoisting method. The vertical alignment tool includes an upper eye plate, a hanging adjustable positioning seat, a hollow sliding cylinder, a suspension wire and a weight, and a hanging adjustable positioning seat. Hanging installation on the upper eye plate, the hollow sliding cylinder is movably set in the hanging adjustable positioning seat, the hanging wire passes through the hollow sliding cylinder, the upper end of the hanging wire is fixed on the upper eye plate, and the lower end is connected with the weight; the upper eye plate is set With eyelets, the hanging adjustable positioning seat includes a fixedly connected installation part and an adjustment part. The adjustment part is provided with a wire-passing opening for the suspension wire to pass through. The hollow sliding cylinder is movably arranged in the adjustment part and communicates with the wire-passing opening. , more than 3 adjusting screws for adjusting the horizontal position of the hollow sliding cylinder are arranged in the adjusting part. The present invention can integrate and unify the functions of the rudder stock axis correction and adjustment tool and the lifting eye plate, and eliminate the situation that the upper and lower theoretical points cannot be centered due to the deformation of the berth and the hull due to the influence of environmental temperature, stress and other factors.

Description

technical field [0001] The application belongs to the technical field of ship installation and positioning, and in particular relates to a vertical alignment tool and a method for alignment and hoisting of a ship rudder system. Background technique [0002] The construction of ship rudder equipment is generally divided into two construction stages: centering and positioning and equipment hoisting. The centering and positioning of the rudder system is to first set up the rudder axis suspension line bracket on the strong structure of the roof in the steering gear cabin, that is, the rib where the center line of the rudder stock is located, and align it to determine the theoretical point on the center line of the rudder stock, and then determine the position on the center line of the rudder stock. The theoretical point below the center line of the rudder stock on the baseline plane, and then process the rudder bearing seat based on the theoretical point above and below the cent...
