Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of construction machinery, and particularly relates to a hook structure mounted on a pulling arm. Background Technique
[0002] A hook is one of the most common lifting tools in hoisting machinery. The hook is often suspended on the steel wire rope of the hoisting mechanism by means of components such as a pulley block. The single hook is simple to manufacture and convenient to use, but the stress condition is not good, and it is mostly used in working occasions with a lifting capacity of less than 80 tons; when the lifting capacity is large, a double hook with symmetrical stress is often used. The laminated hook is riveted by several sheets of cut and formed steel plates. When cracks appear in individual plates, the whole hook will not be damaged, and the safety performance is good, but the self-weight is large, and it is mostly used in cranes with large lifting capacities or for lifting molten steel ladles. The hook is often impacted during the operation process and must be made of high-quality carbon steel with good toughness. The hook mounted on the pulling arm is a device for lifting or carrying heavy objects, and is usually installed on vehicles, cranes or other machinery. It consists of a telescopic arm, and there is a rotatable hook at the end of the arm for hooking the goods for lifting or moving. This device is widely used in construction sites, docks, freight yards and other scenarios, which can greatly improve work efficiency and safety.
[0003] Hooks are divided into single hooks and double hooks according to their shapes; they are divided into forged hooks and laminated hooks according to the manufacturing method. The hook mounted on the pulling arm is usually installed on the hoisting device. During use, the weight of the object itself will cause damage to the hook itself, and the service life of the hook will be reduced after long-term use. For this reason, we propose a hook structure mounted on the pulling arm. Content of the Utility Model
