A test method for container ship cargo hold guide rail based on test device

Abstract

The invention provides a container ship cargo hold guide rail test method based on a test case device, which belongs to the technical field of ship construction. The invention includes the following steps: adjusting the test box device to the size of a 20-foot container through a driving mechanism, hoisting the test box device to the top of the 20-foot container position in the cargo hold by a crane, and keeping the test box device in a horizontal state through a counterweight mechanism; Insert the box device into the 20-foot box position, slide the test box device to the bottom of the cargo hold, check whether the gap between the test box device and the four guide rails meets the design requirements; lift the test box device to the top of the 40-foot box position in the cargo hold , adjust the test box device to the size of the 40-foot box position through the driving mechanism, and keep the test box device in a horizontal state through the counterweight mechanism; insert the test box device into the 40-foot box position, and the test box device slides down to the bottom of the cargo hold. Whether the gap between the box device and the four rail racks meets the design requirements. The invention can improve the test box efficiency of the cargo hold guide rail.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and relates to a method for testing a container ship cargo hold guide rail based on a test box device. Background technique [0002] At present, container ships have become one of the three main types of ships. The area where containers are stacked in the cargo holds is a difficult point in the precision control of this type of ships. The hanging box test is also a key factor affecting the entire ship construction cycle. [0003] The hanging box test in the cargo hold is usually carried out at the dock stage. When the shipyard conducts the hanging box test, only one box can be lifted each time, and each corresponding box must be lifted once. If it is a 20-foot box, it needs to be replaced. The 40-foot container needs to be replaced with a 40-foot container, and the number of containers that need to be tested on the whole ship is very large, so generally speaking, it takes a lot of time to te...

Problems solved by technology

[0004] In addition, during the process of hanging the container, the container will tilt and deflect, and it is necessary to manually straighten the container at the cargo hatch and then push it into the designated guide rails, which reduces the efficiency of the test box and is more dangerous.
