Lifting hook capable of achieving automatic engagement and disengagement

Abstract

The invention relates to a lifting hook capable of achieving automatic engagement and disengagement. The lifting hook comprises a lifting ring, and a fixing plate is arranged at the lower end of the lifting ring and composed of a transverse plate, a vertical plate, a side plate A and a side plate B. A hinged shaft penetrates the middle of the side plate A and the middle of the side plate B, and the hinged shaft is connected with a lifting hook body. A hole A is formed in one side of the upper end of the lifting hook body, a transverse rod A is arranged in the hole A, and a threaded hole is formed under the hole A. A threaded stud is arranged in the threaded hole. A permanent magnet is arranged at the right end of the threaded stud. A hole B is formed in the position, corresponding to the hole A, of the vertical plate. A transverse rod B is arranged in the hole B and connected with a spring, and the other end of the spring is connected with the transverse rod A. Corresponding to the permanent magnet, a hole C is arranged under the hole B. An electromagnet is arranged in the hole C, and the wire-winding end of the electromagnet protrudes out of the hole C. The lifting hook capable of achieving automatic engagement and disengagement has the beneficial effects of high practicability, convenient operation and the high automatic property.

Description

technical field [0001] The invention relates to a suspension hook, which belongs to the field of hoisting machinery, in particular to a suspension hook capable of automatic hooking and unhooking. Background technique [0002] Hook is an important accessory in hoisting machinery. Hooks are usually used together with hoisting equipment such as cranes and cranes. They are often used in major ports, docks, and loading and unloading service companies for loading and unloading of goods; when lifting heavy objects, the hoisting The operation of hooking and unhooking the lifting object is all done manually, which requires the operator to stand in the working area to complete it. For the staff standing in the working area, there are potential safety hazards. Once the lifting object breaks down during the lifting process Swinging, it is easy to touch the staff, thereby injuring the staff; in addition, the manual operation of the unhook operation of the hook has relatively low work eff...
