Description

Technical Field

[0001] This utility model mainly relates to the technical field of crane hooks, specifically a multi-functional hook for cranes. Background Technology

[0002] A crane is a type of lifting machinery widely used in ports, workshops, construction sites, and other locations for lifting and handling operations. A crane mainly consists of a power unit, working mechanism, lifting device, control system, and metal structure. Its metal structure primarily includes the boom and frame, which are typically made of high-strength steel to ensure sufficient strength and stability. The crane hook is one of the key components of the lifting equipment, mainly used to connect the hook to the lifted object to complete the lifting operation. The crane hook is a device used for lifting operations, usually installed on the crane's lifting device, for suspending and lifting goods. It mainly consists of a hook body and a hook base. Common hook materials include carbon steel and alloy steel, which have good strength and wear resistance, ensuring stable performance of the hook in harsh working environments.

[0003] According to application number CN202022932782.6, a crane hook for preventing items from falling off includes a hook, an arc-shaped plate fixedly connected to the lower right end of the hook, and a storage groove opened at the upper right end of the hook. A return spring is fixedly connected to the bottom end of the storage groove, and a slider is fixedly connected to the end of the return spring. The slider is slidably connected to the storage groove, and a limit block is fixedly connected to the end of the slider. A pull block is fixedly connected to the upper right side of the slider, and the upper end of the pull block extends through the hook. A wire rope is fixedly connected to the right side of the pull block. A forward and reverse motor is fixedly connected to the right end of the hook and located inside the arc-shaped plate, and a winding wheel is rotatably connected to the right end of the forward and reverse motor. The winding wheel drives the wire rope to wind up, the wire rope pulls the pull block down, the slider slides into the storage groove and squeezes the return spring, and at the same time, the limit block is stored in the storage groove. At this time, the stop block retracts into the limit groove.

[0004] In existing technologies, the return spring, storage groove, and other structures of crane hooks are often damaged during actual use, which renders the hook unusable and affects the safety of crane lifting. Utility Model Content
