Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of the overhauling and production of railway vehicles, in particular to a wheelset conveying system composed of longitudinal plate chain conveyors and transverse tracks. BACKGROUND
[0002] At present, in the wheelset workshops of each railway vehicle depot in the country, although 2-3 parallel, independent and basically identically laid out overhauling operation lines are arranged along the longitudinal direction of the workshop building, each operation line is composed of longitudinal ground tracks and various overhauling devices, but in the overall layout, no wheelset buffer area shared by the various overhauling devices is provided. For each overhauling device on each longitudinal track, they are arranged in series, and a relatively long longitudinal ground track is provided between each overhauling device on the same operation line to buffer the wheelset of a certain work station, but the ground track on such an operation line cannot be shared by the various overhauling devices.
[0003] When a certain overhauling device fails, its corresponding wheelset buffer section cannot meet the wheelset buffering needs of production scheduling, and at the same time, the wheelset buffer sections on other operation lines may be idle. In addition, due to the relatively large area occupied by the ground turntable, the transverse tracks provided in the wheelset workshops of each railway vehicle depot in the country are very few, which makes it very difficult to transfer the wheelsets between the various longitudinal tracks, and once a certain device on a longitudinal track fails, all the devices on this longitudinal track may stop production.
[0004] Although theoretically, the parallel overhauling of wheelsets between the various longitudinal tracks can be solved by increasing the turntables and transverse tracks, in practice, it is basically difficult to realize due to the limitation of the area of the workshop.
[0005] Another disadvantage is that the transportation of wheelsets between various overhauling stations is mainly realized by manually pushing the wheelsets to roll on the ground tracks, which results in very low overhauling efficiency of the wheelsets and utilization rate of the overhauling devices, and the labor intensity of the workers is very high.
