Abstract

The invention discloses a magnetic crane, which comprises a body, a handle and a control handle, wherein the handle is positioned on the upper end of the body, the control handle is positioned on one side of the body, the control handle is connected with a permanent magnet in the body through a rotating shaft, the permanent magnet is made from a high-performance rare earth permanent magnet material, and the high-performance rare earth permanent magnet material is a neodymium-iron-boron permanent magnet material which comprises the following main components in percentage by mass: 30-35% of neodymium, 20-25% of boron, 25-30% of iron, 8-10% of copper, 5-8% of aluminum and 2-6% of cobalt. Through the mode, the high-performance permanent magnet material is adopted, a magnetic force line is changed by overturning the handle, so that the magnetic crane is in working or closing state, external power supply is not required, and the magnetic crane is safe and energy-saving.

Description

Technical field [0001] The invention relates to the field of lifting equipment accessories, in particular to a magnetic hoist. Background technique [0002] In my country's machining, mold manufacturing, metallurgy and other industries, some heavy steel plates or iron plates, finished steel products or semi-finished products with precision or surface roughness requirements, are mostly lifted by steel wire binding and then hoisted, or electromagnets are used. Hoist. However, the electromagnet is large in size, high in cost, and has many faults and difficult maintenance. The electromagnet consumes a lot of electric energy during operation. Once the power is cut off, accidents are likely to occur. Summary of the invention [0003] The main technical problem solved by the present invention is to provide a magnetic hoist, which adopts high-performance permanent magnetic materials, and changes the magnetic lines of force by turning the handle to make the magnetic hoist in a working or c...
