Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a measuring tool for the diameter of a wire rope. Background Art

[0002] Wire ropes are used on ship cranes. Since the goods carried by ship cranes are relatively heavy, the standards for wire ropes are more stringent. Therefore, it is often necessary to measure and inspect the diameter of wire ropes to check whether the wear degree of the wire ropes has exceeded the specified range of the ship.

[0003] Existing wire rope diameter measuring tools (such as a measuring ruler for measuring the diameter of a wire rope pulley groove and a wire rope disclosed in the patent application No. 2023214976945) can only measure the diameter of wire ropes of specific specifications to judge the wear degree of the wire ropes. Since there are various specifications of wire ropes for cranes, when measuring the diameters of wire ropes of different specifications, compatible measuring tools are required. Although vernier calipers can measure the diameters of wire ropes of different specifications, when using vernier calipers to measure the diameter of a wire rope, it is required to measure at two cross-sections at least 1 m apart on the straight part of the wire rope, and two values are measured in directions perpendicular to each other on the same cross-section. The arithmetic mean of the four measurement results is used as the measured diameter of the wire rope. If necessary, the vernier calipers need to be used for multiple measurements to take the average value, and this data is used to judge whether the wire rope needs to be replaced, which is very troublesome. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above technical deficiencies and propose a wire rope diameter measuring tool to solve the technical problem that existing wire rope diameter measuring tools can only measure the diameters of wire ropes of specific specifications to judge the wear degree of the wire ropes and do not have universality.

Then, the wire rope is clamped into the measuring grooves. According to the measuring groove where the current wire rope is located, the wear condition of the wire rope is judged. If the diameter of the current wire rope is greater than or equal to the diameter of the wire rope in the 95%-wear state, the wear condition of the wire rope is good. If the diameter of the current wire rope is less than the diameter of the wire rope in the 95%-wear state and greater than or equal to the diameter of the wire rope in the 90%-wear state, the wear condition of the wire rope needs to be observed. If the diameter of the current wire rope is less than the diameter of the wire rope in the 90%-wear state, the wire rope needs to be replaced. This wire rope diameter measuring tool can measure the diameters of wire ropes of various specifications to judge the wear degree of the wire ropes, and has strong versatility.
