Problems solved by technology

However, under the traditional method, positioning according to the assembly gap between the anchor lip, the outer plate, and the anchor chain barrel is easy to cause positioning errors, resulting in a large amount of repair work after the pre-installation of the anchor lip

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0019] A method for preinstalling an anchor lip of a bulk carrier in stages, comprising the following steps:

[0020] ①Using the deck as the base plane, place the anchor lip segments of the bulk carrier on the horizontal tire frame in reverse state, find out any two points P1 and P2 on the center line of the tire frame ground, and use the total station to measure the two points P1 and P2 to determine A straight line L1, determine a point P3 on the vertical plane of the straight line L1, make the vertical projection point of the point P3 fall on the straight line L1, and create a vertical plane S1 parallel to the longitudinal section of the hull through the points P1, P2 and P3, see figure 1 .

[0021] ②Use the total station to arbitrarily determine a point P4 in the direct...

Abstract

The invention relates to a mounting method for segmentation preassembling of an anchor mouth of a bulk frighter. According to the method, on the basis of an included angle between surfaces, the anchor mouth is accurately positioned, so that the accuracy and the quality of the segmentation preassembling of the anchor mouth are improved.

Description

technical field [0001] The invention belongs to the technical field of segmental preinstallation of bulk carrier anchor lips, and in particular relates to a segmental stage preinstallation method for bulk carrier anchor lips. Background technique [0002] With the development of the shipbuilding industry, the pace of modern shipbuilding is getting faster and faster. How to further move the construction process forward and shorten the construction period of the slipway is an important means for shipbuilding companies to increase their output value. [0003] The anchor lip of the bulk carrier is pre-installed in the stage of segmentation, which can effectively save at least 3 days of the overall assembly cycle of the berth. However, under the traditional method, positioning according to the assembly gap between the anchor lip, the outer plate, and the anchor chain barrel can easily cause positioning errors, which will cause a large amount of repair work after the anchor lip is...
