Description

Technical Field

[0001] The utility model relates to the field of hoisting equipment, in particular to an adaptive flexible electromagnet. Background Art

[0002] Electromagnetic lifting is a technology that uses electromagnetic force for lifting operations. It uses an electromagnetic lifter, which has an electromagnet built in. When powered on, the electromagnet will generate a magnetic field that causes the object to be adsorbed on the iron, thereby achieving the purpose of lifting.

[0003] Electromagnetic lifting has many advantages, such as strong lifting capacity, which can bear several tons or even tens of tons of weight; it has stable adsorption force, and the adsorption force can be adjusted by controlling the current in the electromagnet to adapt to objects of different weights and shapes; it is easy to use and simple to operate, and the adsorption and release of the electromagnet can be controlled by simply operating the handle or controller; it has a compact structure and does not take up too much space, and can be installed on mechanical equipment such as cranes and hoists, thereby improving the utilization rate of the workplace; there is no ongoing operating cost.

[0004] Existing electromagnetic lifting devices are all composed of a whole electromagnet, which cannot have a good contact surface with the product when lifting arc-shaped products (including tubular, spherical, and cylindrical), resulting in a very poor lifting effect and unable to meet the lifting requirements.
