移动式驾车机总体及机架设计

摘要

近半个多世纪以来，世界各国都在努力进行铁路的技术装备和现代化管理的研究，努力推进铁路运输技术的进步，在很多方面取得了突破性的进展。移动式电动架车机DT105应运而生，它一种不需要动力起运的设备，人工便可推动的、轻便的且具有自动控制同步升降功能的移动式电动架车机。作为铁道电力机务段必不可少的三大检修设备之一的移动式架车机的安全性问题已越来越引起广大设计者的关注。设计与制造移动式架车机时，除考虑该机构能简单、安全、方便地架起电力或内燃机车、推出转向架外，还应注意其自身机架的强度与稳定性问题。本文主要根据工厂实际参观和力学受力分析对机架部分进行优化设计，在设计当中重点是提高移动式架车机机架的稳定性，提高使用寿命和可靠性，以最低的的维修费用，较长的使用周期使移动式架车机具有较高的经济性，机架是移动式架车机的承载基体，不仅承担电动机、底座和所架货车的质量，而且还要承受过作业程中所产生的各种力和力矩。因此，其强度不仅关系到架车的力度，而且还关系到整车的安全性。

ABSTRACT

Since nearly half a century, all the countries in the world to study the railway technical equipment and modern management, efforts to promote the technology of railway transport development, a breakthrough in many aspects. Mobile electric cars machine is a kind of equipment is not required or crane, artificial can promote, portable and mobile electric car automatic control of synchronous lifting function machine.Security problem of mobile car machine one of the three major overhaul equipment as electric locomotive depot for the railway has more and more aroused the attention of designers.Design and manufacture of mobile lifting machine, in addition to considering the mechanism can be simple, safe, convenient up electricity or diesel locomotive bogie, launch, should also pay attention to the strength and stability problems of its own. Analysis on the optimization design of the frame part stress according to the actual plant visits and mechanics, the design is focused on the stability of mobile car machine, improve the service life and reliability, the lowest of the repair costs, economy of long period of use the mobile frame machine frame is high, bearer mobile lifting machine, not only bear the motor, the base and the rack truck quality, but also bear a variety of forces and moments generated operation process. Therefore, its strength is not only related to the car's efforts, but also related to the safety of the vehicle.Keyword:
