摘要
现在,随着铁路运输业务的不断发展,货车运输显得尤为重要。而货车在长期运输过程中,其轮对轴承很容易积聚大量污垢而磨损,严重地影响了货车运行的平稳性,甚至会造成停运,给人们的生产生活带来诸多不便。为保证正常的运输业务不受影响,需要对轮对轴承进行定期清洗。
然而,工厂的实际清洗条件是千差万别的。经考察现场发现,车辆段的拆卸车间和清洗车间是各自独立的,只有一条地下坑道相通,按照厂家要求必须利用这条地下坑道,设计一条运送轴承组件的传输生产线。
目前国外研制的通用运输设备很多,市场需求量也在增加,但都不适应货车轴承的运输,且价格昂贵。虽然我国现在生产的运输设备价格低廉,但主要是应用在地面运输上,适用于地下坑道运输的设备还不多,并且各个生产厂家的运输机在输送能力、效率、适应性及自动化程度等方面各有优缺点。为此,我们在参照其他运输设备的基础上,结合四平车辆段的实际情况,独立开发设计并制造了一套专用的轴承传输线设备,其任务是将拆下的轴承通过地下坑道传送到轴承清洗车间。
该传输生产线控制系统采用PLC自动控制,确保各动作实现自动化。拆下的轴承组件采用托盘盛装,其地面输送设备采用滚筒斜槽传输机械,地下坑道运输设备采用轨道小车传输机械,在地面和地下之间的垂直洞口采用提升机实现升降。为保证提升机和地下轨道小车不发生干涉,提升机采用叉子叉装托盘完成。整个传输线设备适应性强,故障率低,维修方便,其安全系统满足国家生产安全标准。
生产实践表明,该传输生产线上的设备性能完全可以代替进口同类产品,具有良好的性能价格比,自开发以来,获得用户广泛好评。
At present, With the continuous development of railway transport services, truck transportation is especially important. The truck during transport in the long run, its wheel bearings are easy to accumulate a lot of dirt and to wear, It has seriously affected the smooth running of vehicles, and even cause outages and inconvenience to production and living . To ensure the normal transport operations,It need cleaning wheel bearings regularly.
However, in fact, the cleaning conditions vary in the factory. We found that disassembing workshop and cleaning workshop are separate by studying.there is only an underground tunnel between them , according to the manufacturer, we must use this underground tunnel, and design a transmission line and transport bearing components by it.
At present , a lot of general transportation equipment are developed abroad, they are demanded more and more in the market, but they are not fit for transporting truck bearings, and the price is expensive. Now the transportation equipments made in China are cheap,but they are mainly used for ground transportation, the transportation equipments used for underground tunnels are not many, and the transportation equipments have their own advantages and disadvantages in the transportation capacity, efficiency, adaptability and automation etc.To this end, we based on other transport equipment ,and combined of the actual situation of Siping depot, and designed and manufactured a dedicated transmission line equipment which transport bearing components, the task is removed the bearing from the bearings disassembing workshop to cleaning workshop through the underground tunnel.
To ensure the action to realize automation,the transmission line is controled by PLC. The bearing is loaded by the tray dress, the tray dress is transported by the roller chute on ground, the tray dress is transported by the rail car underground tunnels, the tray dress is transported by the elevator in the vertical between the ground and underground. To ensure the elevator is no interference with the rail car, the elevator load the tray dress by it’s pallet fork. The transmission line is adaptable, and it’s failure rate is low, it’s maintenance is easy, its security system can meet the national safety standards.
Production practice shows that the performance of the transmission line equipment can replace the similar products by imports, it has good performance and low cost, which have gotten high evaluetion by user since the development.
