Testing method of anchor mouth in anchor pulling test

Abstract

The invention discloses a testing method of an anchor mouth in an anchor pulling test. According to the testing method disclosed by the invention, through changing the position of a touch point of an anchor rod and the anchor mouth, a modifying starting point, a modifying finishing point, a maximum modifying depth point and a maximum modifying longitudinal profile of the anchor mouth are obtained, and the modifying starting point, the modifying finishing point, the maximum modifying depth point and the maximum modifying longitudinal profile of the anchor mouth are used for guiding modifying work of the anchor mouth in the anchor pulling test, so that the modifying of the anchor mouth is standardized and targeted, and the modifying workload of the anchor mouth in the anchor pulling test is greatly reduced, the modifying time of the anchor mouth in the anchor pulling test is greatly shortened, and the cycle of the anchor pulling test is effectively reduced; and besides, the whole test process is simple, convenient, and controllable, test data is easy to sort and extract, and the test result is genuine and believable.

Description

technical field [0001] The invention relates to the technical field of ship anchor pulling tests, in particular to a test method for an anchor lip in the anchor pulling test. Background technique [0002] The anchor lip is located at the top of the anchor hole, and the test modification of the anchor lip in the anchor pull test plays a decisive role in eliminating the anchor phenomenon. At the beginning of anchor lifting, the anchor lip bears the collision and friction of the shackle. At this time, the plane orientation of the shackle supported by the anchor lip determines the initial state of the anchor; The controlling effect on the anchor is weakened, and the position of the contact point between the anchor lip and the anchor rod plays a decisive role instead. This contact point has essentially become the only fulcrum of the entire anchor weight at this time, and the difference in its position determines the position of the anchor. The different rotation directions of th...

AI Technical Summary

Problems solved by technology

Due to the interference of the plane angle of the shackle and the change of the contact point between the anchor rod and the anchor lip are two test directions, so that one loses sight of the other in the test process; Reduction requirements will affect each other and conflict with each other. The test methods without orientation, fixed value and quantification based on experience make the experimenters at a loss, the test process becomes procrastinated and complicated, and the test results are often difficult to control and unsatisfactory.

Moreover, the endless filling and grinding make the anchor lip parts unrecognizable, making it difficult to measure and record the test data and results, which directly leads to inaccurate test data and greatly reduces the reliability of the final test results.
