Description

Technical Field

[0001] The utility model relates to a lifting device, in particular to a crane with a track dust blowing device. Background Art

[0002] Cranes refer to multi-action lifting machinery that can lift and carry heavy objects vertically and horizontally within a certain range. Cranes mainly include bridge cranes, gantry cranes, crawler cranes, etc. Among them, bridge cranes and gantry cranes can make full use of the space under the bridge to lift materials without being hindered by ground equipment, and have a very wide range of uses. However, both bridge cranes and gantry cranes use I-beams as the moving tracks of trolleys or carts. Dust or other debris can easily fall on the wing plates of I-beams, especially in paper mills, flour mills and other environments where there is a lot of dust. If the dust is not cleaned for a long time, it will accumulate on the track, and the wheels will crush the dust for a long time, which is a high risk.

[0003] In order to clean the crane track, people have developed a series of related cleaning equipment, such as: the automatic crane track cleaning device disclosed in Chinese patent CN208810732U, the sliding track cleaning device and cleaning method of a gantry crane disclosed in Chinese patent CN116425022A, etc. In these cleaning structures, Chinese patent CN116425022A drives the driving wheel to rotate by the crane, and then drives the fan blades to rotate for blowing, which means that the size of the fan blade wind force depends on the moving speed of the crane; Chinese patent CN208810732U achieves the cleaning effect by crushing or pushing the debris to move by the crushing wheel, but this solution cannot clean smaller particles.
