机车柴油机升降翻转架的设计原理及应用

The Design Principle and Application of Locomotive Diesel Engine Lifting Turnover

机车柴油机升降翻转架设备可用于铁路机务段机车中修的过程中,它是柴油机机体拆卸和总装作业的必要设备。目前,该设备已被广泛应用在各铁路机务段。经过观察北京内燃机务段车间工人使用该设备的情况发现,工人在使用该设备时,存在2点不便之处:1该设备的盘车机构驱动装置不能同时兼顾东风4型车和东风8型车的柴油机,一般柴油机升降翻转架只设置1套盘车机构驱动装置,工人们只能通过手动的方式来操作另一种车型柴油机的盘车机构;2现场没有能解决柴油机油底壳拆装的机械设备,工人们只能把油底壳架在木桩子上对其进行拆装作业。这些问题反映出了柴油机升降翻转架设计中的不足之处,需要改进其中存在的问题。主要阐述了柴油机升降翻转架的设计原理和结构特性,同时,从设计的角度出发,改进了该设备自身存在的问题,以减轻工人的劳动强度,提高生产效率。

The locomotive diesel engine lifting overturning frame device can be used to process of the railway locomotive depot in, it is a necessary equipment for diesel engine disassembly and assembly operations. At present, the device has been widely used in the railway locomotive depot. Through the observation of Beijing diesel locomotive depot workshop workers using the equipment is found, workers in the use of the equipment, there are 2 inconvenience： 1diesel engine turning gear the equipment driving device can also take into account the Dongfeng 4 type car and Dongfeng 8 type vehicles, general diesel engine lifting overturning frame set only 1 sets of jigger mechanism driving device, barring mechanism workers only by manual way to operate another vehicle diesel engine; 2the site cannot solve the diesel engine oil bottom shell mechanical equipment disassembly, workers can only put the oil pan in the wooden frame on the assembly and disassembly operation. These problems reflect the deficiency of diesel engine lifting overturning frame design, the need to improve the existing problems. Mainly expounds the design principle and the structure characteristic, diesel engine lifting turnover at the same time, from the design point of view, improved the equipment of their own problems, in order to reduce the labor intensity of workers, improves the production efficiency.
