Description

Technical Field

[0001] The invention relates to the technical field of container hatch cover foot installation, in particular to a double-hole container foot center reference marking tool. Background Art

[0002] Repairing a ship usually requires repairing more than 30 hatch covers, and the main work is focused on the replacement of the top plates. However, because the hull is a container hull, a large number of container feet and accessories are arranged on the hatch cover top plates. According to the results of the engineering survey, all the container feet and accessories are severely corroded and even need to be completely replaced; When positioning the box feet, the center line of the box feet needs to be aligned with the pre-marked installation line. Since all the center reference lines of the box feet are made on the top plate of the box feet when leaving the factory, and the average height of the box feet is about 120mm, all the top plate center lines need to be led to the bottom of the box foot side panels to facilitate alignment with the reference lines.

[0003] The usual practice is to use a square to complete it. Since it is a double-hole box foot, there are a total of 6 center lines that need to be drawn out for each box foot. This will be a very tedious step, requiring a lot of auxiliary time and causing great trouble to the installers. Therefore, this application designs a fast and efficient marking tool to solve the above problems, thereby shortening the positioning and installation time. Summary of the invention
