Abstract

The invention discloses a pulling force test method for a ship lashing eye plate. A test tool which includes an installation surface the same with the surface of a mast to be welded of the lashing eyeplate is provided, a plugging groove is formed in the installation surface, the lashing eye plate is welded into the plugging groove, the lashing eye plate or the test tool is fixed in position, a test pulling force is applied to the test tool or the lashing eye plate, the rated load of the lashing eye plate<= the test pulling force<= the breaking limit load of the lashing eye plate, and after standing time T, the test pulling force is removed, and weld seam detection and surface detection are carried out on the lashing eye plate. The lashing eye plate is welded to the test tool as to the mast, pulling force test can be carried out on the lashing eye plate directly, non-destructive test is realized, more accurate test data can be obtained, sampling or repeated test is omitted, and the test speed and quality are improved; and whether the lashing eye plate satisfies requirements after the pulling force test can be determined via weld seam detection and surface detection.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a tensile test method for a ship's mooring eye plate. Background technique [0002] The rated load of the lanyard eye plate of the sailing ship (that is, the maximum working load that the lanyard eye plate can withstand when working) is 9.5T, and the installation node is a method of opening a hole on the mast and inserting welding. The eye plate of the lanyard is a strong stress member. According to the requirements of the classification society, such a strong stress member needs to be subjected to a tensile test before use. The tensile test of the existing lanyard eye plate is to carry out the sample tensile test in the laboratory after sampling. In order to improve the accuracy of the test, more than ten groups of samples are usually prepared for the test, and the tensile test is performed on each group of samples one by one. And form a record, and finally determine wheth...
