Description

Technical Field

[0001] The utility model belongs to the technical field of locomotive sanding, and more specifically, relates to a suspended automatic in - depot sanding system. Background Art

[0002] At present, automatic sanding equipment is mainly installed at positions such as the access and departure lines and outdoor end lines. Locomotive maintenance operations are concentrated in the maintenance depot. Due to the increase in the number of locomotives to be maintained, the maintenance positions on a single line have severely restricted the locomotive maintenance time. In rainy and snowy seasons and with extended train operation routes, the amount of sand added to locomotives is large. Currently, there are problems such as high labor intensity, difficult working environment, and poor labor safety protection in outdoor locomotive maintenance operations.

[0003] There are two problems with outdoor automatic sanding equipment. First, all locomotives must queue up at limited positions for sanding operations. In many maintenance yards, locomotives arrive concentratedly, and sanding personnel need to work intensively to complete the sanding work of a large number of locomotives in a very short time. The existing equipment cannot meet the high - efficiency sanding requirements. Second, the locomotive sanding operation is on a 24 - hour basis, and the existing sanding equipment is installed outdoors. In rainy and snowy seasons, the working environment for sanding personnel is difficult. Third, the labor intensity is high. For example, to complete 100 daily maintenance locomotives, about 10 tons of sanding volume needs to be completed. Such a heavy workload needs to be completed on a single maintenance position, seriously exceeding the physical limit of the staff; outdoor operations and high - intensity work seriously affect the physical and mental health of the operating personnel.
