Description

Technical Field

[0001] The utility model relates to the technical field of electric control devices for crane hoisting mechanisms, in particular to an electric control device for crane hoisting mechanisms. Background Art

[0002] In the prior art, the realization of the logical functions of the electric operating device completely relies on the relay switching principle. Each logical function needs to be realized through the interaction of several relay switches. As the number of electric operating functions increases, in order to meet the corresponding electric operating functions, the electric operating control device needs to add a large number of relay elements. The increase in relay elements increases the dissipated heat, and the dust-proof performance when dissipating heat is poor, which causes dust to enter the interior of the electrical box and easily damage the internal electrical components.

[0003] An electrical control device for a crane hoisting mechanism disclosed in the Chinese utility model patent application disclosure CN217201722U has the advantages of easy installation and disassembly, improved dustproof performance, etc., but the electrical control device for the crane hoisting mechanism still has disadvantages: First, during the lifting process of the crane, lubricating oil, engine oil and other substances on the boom or the hoisted objects may be thrown off, and the thrown objects may fall on the top of the electrical control device, causing dirt; Second, the electrical control device for the crane hoisting mechanism adopts a fan to dissipate heat inside the device, but in actual use, it is a problem when the internal fan needs to be turned on for heat dissipation. Turning it on all the time will cause energy waste, and it is not very convenient to use without a clear operating mechanism. Utility Model Content
