Description

Technical Field

[0002] With the continuous improvement of my country's mechanization level, various types of construction machinery and equipment have been widely used. Through simple mechanical design improvements or the installation of additional components, these equipment can meet a variety of operational needs. This not only improves the convenience and efficiency of mechanical equipment use, but also achieves the goal of "one machine for multiple uses", significantly improving mechanical performance and reducing workload and difficulty.

[0003] In specific application scenarios, such as drilling rigs, wire ropes, as one of the key components, are subject to heavy loads and frequent movements for long periods of time, making them prone to wear and even breakage, necessitating regular replacement. During the wire rope processing process, especially after installing the aluminum sleeve and heart ring, to ensure the quality of the wire rope, the heart ring must fit tightly against the wire rope. However, in the absence of specialized tools, this is often achieved by manually tightening the wire rope. This method is not only inefficient and difficult to guarantee processing quality, but also requires additional manual coordination, increasing labor intensity and operational difficulty.
