Description

Technical Field

[0001] The utility model belongs to the technical field of steel product life test, in particular to a special steel product life test device. Background Art

[0002] The life of a wire rope mainly refers to the phenomenon of wire breakage due to the influence of external stress. If a wire rope that has reached this level continues to be used, it may break. The reason why the wire rope breaks during use is mostly not due to a decrease in strength, but metal fatigue caused by the frequent bending stress during use. The greater the alternating stress and alternating frequency amplitude of the bending stress and tensile stress borne by the wire rope, the earlier the metal fatigue of the wire will appear. Wire ropes used in the open air or in harsh environments will always be subject to a certain degree of rust, which shortens their life, especially internal rust, because it is extremely difficult to detect from the outside. The deterioration of the wire rope is unexpected and it is very dangerous to use. Therefore, the factor of rust should be fully considered for ships, seaports, mine water, sulfur dioxide and other environments.

[0003] The existing Chinese patent publication number CN216695529U is a steel cable life test device that sets the test frequency and speed through the human-machine interface of the main control box. After the motor control box receives the command from the human-machine interface, it instructs the drive motor to operate at the established speed and frequency. The drive motor drives the cam, which drives the rotating shaft through the connecting rod. The rotating shaft drives the rotating disk to rotate up and down alternately according to the set frequency and speed. The rotating disk drives the steel cable group, and the pulley group drives the adjustable counterweight block. Under the guidance of the guide rod, it moves up and down to simulate the movement trajectory of the steel cable in actual use.

[0004] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0005] In actual use, the steel cable will work in some humid environments, causing the steel cable to corrode after long-term contact with a large amount of moisture, thereby affecting the service life of the steel cable and causing inaccurate test results. Utility Model Content
