Abstract
This utility model discloses a self-locking lifting clamp for oil pipes, including a clamp sleeve and auxiliary components. The clamp sleeve has an open top and bottom surface and a closed side surface, and its interior is hollow. The auxiliary components are arranged inside the clamp sleeve. The auxiliary components include a fixed auxiliary unit and a detachable auxiliary component. The detachable auxiliary component is located directly below the middle of the two fixed auxiliary components. Two anti-wear rods are also horizontally arranged on the inner bottom of the clamp sleeve. This utility model allows the sling to move freely without being removed, thanks to the fixed auxiliary unit and the detachable auxiliary component, resulting in high lifting efficiency. The two anti-wear rods at the bottom of the clamp sleeve prevent the sling from being scratched during use, improving lifting safety and reducing safety risks.
