Background

The bridge crane is a hoisting device which is transversely erected above workshops, warehouses and material yards for hoisting materials, and the bridge crane is called as the bridge crane because two ends of the bridge crane are located on high cement columns or metal supports and are shaped like a bridge. The bridge frame is a basic component of a bridge crane and consists of a main beam, an end beam, a walking platform and the like. The main beam span frame is arranged above the span, the two ends of the main beam are connected with end beams, the outer sides of the two main beams are provided with walking platforms, and the walking platforms are provided with cart moving tracks. The whole bridge crane is dragged by the cart moving mechanism to move on the guide rail along the length direction of the workshop. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated frames at two sides, materials can be lifted and transported by fully utilizing the space below the bridge frame and are not blocked by ground equipment, and because the existing bridge crane is mostly installed in workshop workshops with severe environmental conditions, especially the bridge crane for metallurgy, a large amount of dust and solid particles are accumulated on the crane rail, and particularly in the workshops such as tank dumping, desulfuration, converter and refining, the inside and the outside of the rail are easy to form accumulated slag and splashed high-temperature flowing slag. When the bridge crane vertically moves along the track, the dust and the solid particle that wheel and track contact surface sneaked into can lead to wheel and track wearing and tearing aggravation, reduce wheel and track life, still lead to the hoist to move unstably easily, cause the fish tail to the driving wheel, probably lead to the driving to derail when serious, if the dust in the untimely clearance track simultaneously, can lead to in the workshop secondary raise dust serious, air pollution brings the injury on the health for the operation personnel.

In order to solve the potential safety hazard, in the prior art, the track is generally cleaned in a manual periodic cleaning mode. However, the bridge crane is manually cleaned, so that the cleaning work is heavy, the labor burden is large, time and labor are wasted, and meanwhile, the bridge crane is higher in position, and the high-altitude operation has quite large operation difficulty and risk. If the industrial dust collector in the prior art is adopted for treatment, the dust and the slag in corners and gaps can not be cleaned by common industrial dust collection due to the existence of the rail pressing plate and the bolts.

In view of the above-mentioned defects, it is actually necessary to design an automatic ash removal device for a track of a bridge crane.
