Description
Technical Field
The invention relates to the technical field of steel wire rope detection, in particular to equipment and a method for testing alkali resistance of a steel wire rope.
Background
Steel ropes are commonly used in hoisting, traction and securing projects, which may involve alkaline environments, such as in construction sites, chemical plants or marine environments. The alkaline environment affects the durability and safety of the wire rope, so that an alkali resistance test is required to be performed on the wire rope to ensure that the wire rope can be used normally in the alkaline environment and maintain good performance. Therefore, the steel wire rope can be prevented from being damaged or invalid due to an alkaline environment in the use process, so that the safety and the reliability of engineering are ensured, and the alkali resistance test of the steel wire rope is a method for evaluating the tolerance performance of the steel wire rope under the alkaline environment. Such tests are commonly used to determine whether a wire rope is suitable for use in alkaline conditions and to understand the alkali resistance of a wire rope in alkaline environments of different concentrations.
Most of the traditional alkali resistance tests of the steel wire rope are to directly put the steel wire rope into an alkaline solution, and manually observe the corrosion degree of the surface of the steel wire rope after a period of time. The method has larger error, and particularly for some steel wire ropes with small corrosion degree, the corrosion degree of the steel wire ropes is difficult to judge manually.
The Chinese patent with the publication number of CN105067508B discloses a steel wire rope alkali resistance testing device and a method, the device comprises a base, a box body, a driving device and an upper cover, wherein the box body is arranged on the base, an alkaline solution containing fluorescent solution is contained in the box body, two connectors are correspondingly arranged on two side walls of the box body through rotating shafts, a bearing is arranged between the rotating shafts and the box body, a steel wire rope to be tested is arranged between the two connectors, the steel wire rope to be tested is positioned below the liquid level of the alkaline solution, the upper cover is arranged at the top opening of the box body, an observation window is arranged at the middle of the upper cover, and two bosses are correspondingly arranged above the liquid level of the alkaline solution on the two side walls of the box body. The steel wire rope alkali resistance testing equipment can enable the corrosion degree of the steel wire rope to be easily and quickly judged by naked eyes, and further the alkali resistance of the steel wire rope can be accurately evaluated.
The prior test equipment judges the alkaline corrosion condition of the steel wire rope by means of naked eyes, however, the result obtained by observing the steel wire rope by manual observation is more unilateral, the alkaline solution containing fluorescent liquid only can observe the outer surface of the steel wire rope by manual observation when the steel wire rope is corroded, but the internal condition of the steel wire rope cannot be observed, so that the whole load bearing capacity of the steel wire rope after being corroded by alkaline environment cannot be obtained by observing the fluorescent condition of the outer surface of the steel wire rope, and the prior art scheme needs to be improved.
