Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to a three-dimensional measuring tool for container ship guide rails. Background Technology
[0002] Container ships have numerous guide rails installed on the transverse bulkheads of the cargo holds for loading and stacking containers. To ensure rapid, smooth, and accurate loading and stacking, the guide rails require high installation precision, with a tolerance within ±2mm during installation. During the bulkhead construction phase, we use a total station to inspect the guide rail installation accuracy. To verify this, two points are required at each inspection location on the guide rail. However, due to the large number of guide rails on the bulkhead (generally 6-7 on one side) and their double-sided installation, there are approximately 14 inspection locations per guide rail, with two points required at each location (depending on the guide rail's length and half-width dimensions). This results in approximately 392 inspection points on both sides of a single bulkhead, leading to a lengthy inspection time and subsequent data analysis. Furthermore, using a moving target for measurement is inefficient, as the target cannot fully align with both sides of the guide rail angle steel, and the target's height is insufficient. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a three-dimensional measurement fixture for container ship guide rails.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A three-dimensional measuring fixture for container ship guide rails includes a fixture body, which is made of steel plate cut by cutting. A rectangular notch is provided in the upper right corner of the fixture body. A measuring moving target is placed in the rectangular notch and is closely attached to the two sides of the rectangular notch. The left side and lower end face of the fixture body are detachably connected to the guide rail.
[0006] Furthermore, the lower left corner of the rectangular notch is rounded.
[0007] This design ensures that when the moving target is installed during measurement, both sides of the magnet base of the moving target are in close contact with both sides of the rectangular notch in the upper right corner of the tooling, thus guaranteeing measurement accuracy.
[0008] Furthermore, the lower left corner of the tooling body is chamfered.
[0009] This design prevents the edges and corners of the tooling from colliding with the corners of the guide rail, ensuring that both sides of the tooling fit tightly against both sides of the guide rail.
[0010] Furthermore, the tooling also includes multiple magnets, and multiple slots are provided at intervals on the left side and the lower end of the tooling body. The shape of the slots is adapted to the shape of the magnets, and multiple magnets are respectively embedded in a slot. The tooling body is detachably connected to the guide rail through multiple magnets.
[0011] With this configuration, multiple magnets are embedded in the left and lower sides of the fixture, ensuring that the fixture remains stable and does not tilt while adhering to both sides of the guide rail, thus guaranteeing measurement accuracy.
[0012] Furthermore, the magnet is circular in shape.
[0013] Furthermore, the tooling body is provided with light-reducing holes. This design ensures that the tooling is easy to handle and convenient to use.
[0014] This utility model presents a compact and lightweight 3D measurement fixture for container ship guide rails. It features a high degree of fit with the guide rail and moving target, resulting in high precision. Furthermore, this invention reduces the number of measurement points on the guide rail from two to only one, improving work efficiency and facilitating data analysis. The use of this fixture not only increases inspection efficiency but also reduces the waiting time for the construction of transverse bulkhead sections. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] like Figures 1-4As shown, a three-dimensional measuring fixture for container ship guide rails includes a fixture body 1, which is made of steel plate by cutting. A rectangular notch 11 is provided in the upper right corner of the fixture body 1. A measuring moving target is placed in the rectangular notch 11 and is closely attached to the two sides of the rectangular notch 11. The left side and lower end face of the fixture body 1 are detachably connected to the guide rail.
[0022] Furthermore, the lower left corner of the rectangular notch 11 is rounded 13.
[0023] Understandably, this fixture is used in conjunction with a moving target. The fixture has a rectangular notch 11 in the upper right corner, with a rounded lower left corner to ensure a tight fit between the magnet base of the moving target and the two sides of the rectangular notch 11 during measurement, guaranteeing measurement accuracy. The target plate can rotate 360 degrees without colliding with the fixture. In this embodiment, the main dimensions of the fixture are 110mm high * 90mm wide * 15mm thick. These dimensions were determined based on the guide rail height and the moving target height, prioritizing ease of use. This ensures the moving target is visible from all angles during measurement while maintaining a compact fixture size for ease of use.
[0024] Furthermore, the lower left corner of the tooling body 1 is chamfered by 14.
[0025] This design prevents the edges and corners of the tooling from colliding with the corners of the guide rail, ensuring that both sides of the tooling fit tightly against both sides of the guide rail.
[0026] Furthermore, the tooling also includes multiple magnets 2, and multiple slots are provided at intervals on the left side and the lower end face of the tooling body 1. The shape of the slots is adapted to the shape of the magnets 2, and multiple magnets 2 are respectively embedded in a slot. The tooling body 1 is detachably connected to the guide rail through multiple magnets 2.
[0027] With this configuration, multiple magnets 2 are embedded in the left and lower sides of the fixture, ensuring that the fixture remains stable and does not tilt while adhering to both sides of the guide rail, thus guaranteeing measurement accuracy. In this embodiment, there are four magnets 2, with two on the left and two on the lower side of the fixture body 1. Of course, in other embodiments, the number of magnets 2 can be other numbers, such as six or eight.
[0028] Furthermore, the magnet 2 is circular in shape. In this embodiment, the diameter of the circular magnet is 10mm. Of course, in other embodiments, the diameter of the circular magnet 2 can be determined according to the thickness of the tooling body 1; in other embodiments, the shape of the magnet 2 can also be other shapes, such as a cube.
[0029] Furthermore, a light-reducing hole 12 is provided on the main body 1 of the tooling. This design ensures that the tooling is easy to handle and convenient to use.
[0030] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
