Description

TECHNICAL FIELD

[0001] The utility model relates to hydraulic device technical field, especially point to a kind of hydraulic rope tightener. BACKGROUND

[0002] Hydraulic rope tightener is a kind of mechanical equipment for ensuring that cable gear (such as steel wire rope) maintains proper tension, which is widely used in various occasions requiring cable tension maintenance, such as cranes, elevators, mining machinery, port handling equipment, etc. Through the powerful and precise pressure control provided by the hydraulic system, the device can effectively adjust and maintain the tension of the cable. In the mining industry, hydraulic rope tightener is often used.

[0003] The existing hydraulic rope tightener is mainly composed of a hydraulic cylinder and a rope body. The hydraulic movement of the hydraulic cylinder is used to realize the extension and fixation of the rope body. In the mining operation process, the mining environment is extremely complex. Due to the continuous process of ore mining, crushing, transportation and other links, a large amount of dust, fine powder and other pollutants are diffused in the air. These pollutants have different particle sizes and complex compositions, including mineral particles with high hardness. During operation, the pull rope, as a key transmission component, moves frequently. When these pollutants come into contact with the pull rope, they will gradually adhere to the surface of the pull rope. With the passage of time and the continuous operation of the pull rope, the pollutants act as tiny abrasive particles, continuously rubbing against the surface of the pull rope during the movement of the pull rope. This long-term friction damages the structural integrity of the pull rope, gradually wears away the outer protection of the pull rope, and even penetrates into the internal fiber structure, ultimately leading to a decrease in the strength of the pull rope and an easy occurrence of breakage and other damage, which seriously affects the normal operation of mining production.
