Embodiment Construction
[0022] The technical solutions of the present invention will be clearly and completely described below through specific embodiments.
[0023] The invention provides a method for on-site analysis and test of failure of a steel wire rope, the specific process of which is as follows: figure 1 shown, including the following steps:
[0024] S1. Select the wire rope wire material to be tested: Measure the gauge length specified in the test on the wire rope sample to obtain the test wire rope with the gauge length length, reserve clamping parts at both ends of the test wire rope, and place the gauge length on the wire rope sample. Take five groups of the same wire rope as the test wire rope, and four in each group;
[0025] S2. Group labeling: group and label five groups of wire ropes, which are group A, group B, group C, group D and group E;
[0026] S3. Grouping test: Corrosion test is performed on two of the steel wires in group A, and the conditions of the corrosion test of the...

The invention relates to a steel wire rope failure on-site analysis test method, which specifically comprises the steps of S1, selecting required steel wire ropes to be tested; S2, grouping and labeling; S3, testing in a grouped manner; S4, performing a contrast test; and S5, observing the test and recording test data. According to the invention, multiple groups of steel wire ropes are arranged for testing, single variables are controlled at the same time for mutual comparison and reference, the environment in which the steel wire is used in an actual situation is simulated after the steel wire is produced so as to improve the authenticity of the test; two steel wire ropes in each group are in the same test environment, the other two steel wire ropes are in another test environment, and the same-group reference is carried out so as to improve the comparability of the test; and the single contingency of the test is avoided by arranging multiple groups of steel wire ropes and arranging four steel wire ropes in each group, and the accuracy and credibility of the test are further improved.
Description
technical field [0001] The invention relates to the technical field of wire rope detection, in particular to a failure on-site analysis and test method of a wire rope. Background technique [0002] The steel wire rope is a helical wire bundle in which the steel wires whose mechanical properties and geometric dimensions meet the requirements are twisted together according to certain rules. The steel wire rope is composed of steel wire, rope core and grease. The rope core is the center, and is twisted into a helical rope by a certain number of strands. In material handling machinery, it is used for lifting, pulling, tensioning and bearing. [0003] Wire ropes are used in various situations. In order to accurately determine when the wire rope fails, it is necessary to first understand the reasons for the failure of the wire rope, and then standardize the use in real life through tests to further improve safety. [0004] In order to solve the above problems, the present applica...
