Abstract
Description
Technical Field
[0001] This utility model relates to the field of hook technology, specifically a hook structure mounted on a boom. Background Technology
[0002] A hook is a key metal component in lifting machinery used for suspending, grabbing, and moving heavy objects. It is usually forged from high-strength alloy steel and has a curved hook-shaped structure (such as a single hook, double hook, or rotating hook). It is connected to the crane wire rope or chain through a top lifting ring. Its arc design can evenly distribute load stress and is equipped with a safety locking device. It is widely used in construction, ports, logistics and other scenarios.
[0003] Patent application CN202022585125.9 discloses a reinforced hook mounted on a boom arm, comprising a mounting base, a hook fixedly mounted on the lower end face of the mounting base, an anti-slip plate rotatably connected to the side of the hook, a slot on the side of the hook, a locking block movably mounted inside the slot, a pad fixedly mounted on the outside of the locking block, and an anti-slip protrusion fixedly mounted on the upper end face of the pad. This reinforced hook mounted on a boom arm has three hooks at the bottom of the mounting base, increasing the contact area between the hook and the cargo, reducing pressure, and allowing the other two hooks to support the lifting rope even if one hook is damaged, improving safety. A pad is provided at the point where the hook contacts the cargo; the pad can move along the slot to reduce friction between the cargo and the hook when the cargo sways. The friction generated is mitigated by a spring, which cushions the fixed seat through the movable seat, preventing damage to the hook due to sudden tension and greatly improving the strength of the hook. Based on the above patent search and combined with the existing hook structure on the boom, it was found that traditional hooks have significant structural performance defects in engineering applications. The connection structure between the hook body and the load-bearing component is usually a single weld, resulting in uneven stress distribution and generally low maximum tensile strength, which is difficult to meet the strength requirements of heavy lifting scenarios. More seriously, its open hook structure lacks an adaptive locking device. When the working environment experiences mechanical vibration, transportation bumps, or lateral loads caused by sudden changes in the center of gravity of the goods, it is easy to cause heavy objects to fall. In addition, when suspending objects, the objects may sway, which increases the risk of heavy objects falling.
[0004] Based on this, the present invention designs a hook structure mounted on a boom to solve the above problems. Utility Model Content

Then the second steel rope 307 is passed through the second slot 309 and the second limiting screw 310 is tightened to secure the second steel rope 307. This achieves the effect of limiting the items and improves the hanging stability and safety of the items.
[0033] The working principle of this utility model is as follows: The hook structure mainly consists of a wire rope 1, an anti-disengagement hook hanging mechanism 2, and a limiting mechanism 3. At the start of operation, the wire rope 1 connects the entire hook structure to the crane or other lifting equipment through its strong tensile strength. Below the wire rope 1 is an integrally formed anti-disengagement hook hanging mechanism 2, which includes an integrally formed steel frame 204, serving as the main support structure to ensure overall stability. A bearing plate 205 is fixedly installed in the middle of the integrally formed steel frame 204 to distribute and bear the weight from the lifted object. A support column 206 passes through the bearing plate 205, and its lower end is fixedly connected to a support steel plate 208 via an mounting block 207. A hook body 209 is installed inside the support steel plate 208 for direct hanging. In particular, to enhance the stability and safety of the hook body 209, an auxiliary structure composed of a first steel plate 201, a second steel plate 202, and a pulley body 203 is designed. The pulley body 203 not only facilitates the smooth movement of the wire rope 1, but the first steel plate 201 and the second steel plate 202 are also tightly connected by multiple bolts to form a sturdy frame. A limiting steel rod 210 is inserted into the right end of the hook body 209. The limiting steel rod 210 is fixed by a limiting pin 212 in the support seat 211. At the same time, an adjusting screw 215 is installed on the support frame 213 at the rear end of the support steel plate 208. By rotating the adjusting screw 215, the limiting steel rod 210 connected to the connecting plate 214 can be pushed to further limit the hook body 209. In addition, when hanging items, these two steel ropes can be used flexibly to wrap around the hanging items to improve the hanging stability of the items. The first steel rope 302 and the second steel rope 307 are fixed by slots on the first threaded seat 303 and the second threaded seat 308, respectively, and are tightened by the first limiting screw 305 and the second limiting screw 310.
