Background
The permanent magnet crane is a device for utilizing the permanent magnet crane to adsorb materials to finish lifting operation of the materials, wherein the permanent magnet crane is also called a permanent magnet crane, a magnetic crane, a lifting magnet, a lifting permanent magnet, a permanent magnet and the like. The device has the characteristics of small volume, strong holding force, no electricity, no residual magnetism on the weight, high safety coefficient and the like. Therefore, the device is widely applied to the installation and the transportation of steel materials, flat mechanical parts and various dies.
However, when machined parts of iron plates, section steel or other ferrous materials are machined, certain amounts of scrap iron and other impurities are extremely prone to remain on the surfaces. When the iron plate is adsorbed by the permanent magnetic jack on the current permanent magnetic crane, the iron filings are firstly adsorbed on the permanent magnetic jack, and then the hung object is adsorbed on the permanent magnetic jack, so that the iron filings and other impurities are mixed between the hung object and the permanent magnetic jack, the gap between the permanent magnetic jack and the iron plate is increased, and the attraction magnetic force is reduced. When the suspended matter is large in weight, the suspended matter and the permanent magnet jack are more unstable in adsorption due to the existence of scrap iron, so that the suspended matter is very likely to fall off in the process of hoisting, and safety accidents are caused seriously.
Therefore, we design a permanent magnet adsorption device for a crane.
