The present invention relates to a measuring system and an inspection method for container cell guides that enable inspection to be performed regardless of ambient conditions.

Generally, a cargo hold in which a container is loaded is installed in a container ship. The cargo hold is of sufficient width and depth to stack multiple containers. These cargo hold should be made to a suitable size to easily load or unload the container, while increasing the loading efficiency of the container. In addition, the cell guide constituting the wall of the cargo hold should maintain the correct verticality to smoothly lift and lower the container. Accordingly, the cell guide is measured to determine whether or not the cell guide is correctly installed.

1 is a schematic perspective view for explaining a cell guide measurement process of a typical container.

As shown in Figure 1, the cargo hold (1) of the container ship for loading the container is a cell guide for guiding the corner of the container model (4) which is installed at four angles each spaced apart from each other and inserted into the interior space ( 2) and the bottom (3). It is composed of enough depth and width of proper space to stack several containers.

Measurement of the cell guide (2) according to the prior art made of such a configuration to check whether the actual size of the container model (4) by lifting the crane (5) directly put in the place where the cell guide (2) is installed, Next, lower the container model (4) to the floor and check how much the gap between the bottom of the cone and the container model (4) installed to protrude on the bottom surface of the cell guide (2) to attach a leveling pad.

Then, the operator measures the cell guide 2 by hand using a jig having a tape measure or spatula shape while moving to each floor position.

However, according to the cell guide measurement according to the prior art as described above, the container model is taken into the crane to take a way to put one by one, the crane waiting time is excessive and friction with other work occurs, the weather due to wind and rain Since the work is delayed depending on the situation, there is a problem that a huge loss occurs due to the delay of the entire air.

In addition, it is possible to work only during the day by the tape measure and time check, there is a problem that the work efficiency is reduced, the accuracy of the measurement value is reduced by the measurement of the aerial work and the hand signal, there is a high risk of safety accidents.

The present invention has been proposed to solve the problems of the prior art, and its object is to provide an automatic measurement system using a sensor to facilitate the inspection without crane and container model and to execute the inspection regardless of the surrounding conditions. This improves the efficiency and safety of the work and enables accurate measurement.
