Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a rotating safety hook rigging. Background Art

[0002] A rotating safety hook sling is a hook that can be adjusted and rotated at any angle. It connects to other rigging components for flexibility and safety. This hook design allows operators to adjust the lifting angle as needed during the lifting process, improving efficiency and safety. A rotating safety hook sling typically consists of a shackle, a swivel, and a safety hook. The shackle is typically die-forged from 40Cr alloy steel, offering a safety factor of four times the working tension. The swivel is also machined from 40Cr and incorporates a pressure bearing to ensure smooth rotation. The safety hook is die-forged from 35CrMo, achieving a safety factor of five times, further enhancing overall safety. This sling is widely used in various lifting applications, particularly in oil fields and construction sites, where frequent adjustments to the lifting angle and direction are required. Using a rotating safety hook sling not only improves work efficiency but also effectively reduces operational risks, ensuring the safety of both personnel and equipment. With the development of society, rotating safety hooks are increasingly being used when cargo needs to be lifted.

[0003] Existing equipment, such as CN202358830U, a rotating hook rigging, belongs to the field of mechanical design. This hook rigging consists of four parts: a rotating eye, a locking rod, a hook body, and a safety device. The rotating eye has a through-hole at the center of its base. The locking rod has threads at its upper end and an inverted U-shaped groove at its end. The upper end of the locking rod is inserted into the through-hole of the rotating eye and a flat washer, and a slotted nut is screwed into the threaded portion and locked with an elastic cylindrical pin. The middle of the locking rod is clamped into a vertical groove at the upper end of the hook body and connected with rivets. The safety device and torsion spring are fixed to the vertical groove at the upper end of the hook body with an elastic cylindrical pin. The ends of the torsion spring are supported on the hook body and the safety device, respectively. The safety device's boss engages the notch in the locking rod. During use, the safety device is pressed to release its boss from the notch in the locking rod, disengaging the safety device. The locking rod is then pulled open and a rope is hooked in. During lifting, a slight force is applied, and the lower end of the locking rod rebounds to the end of the hook body, closing the notch.

[0004] When workers need to lift goods, they connect the goods to the hook rigging so that the hook rigging can lift the materials. However, when the hook rigging works on rainy days, rainwater will enter the gaps between the hook rigging, and the rotating ends of the hook rigging will lose the protection of the anti-rust film due to severe wear, causing the rainwater to erode the rotating ends of the hook rigging for a long time, which will cause the hook rigging to get stuck.
