Abstract

The paper proposes the concept of using a machine with a combined stroke based on a wheeled excavator equipped with a tilt-turning device for the repair and maintenance of railway tracks. The current maintenance of the track includes the systematic supervision of the condition of the track structures and track devices and their maintenance in a condition that guarantees the safe movement of trains. It is grounded the expediency of the using road-rail vehicle and the use of tilt-turning devices for various types of work, such as lifting and straightening the track, changing sleepers, laying ballast, clearing railway tracks from snow, and much more. A promising domestic design of a tilt-turning device has been developed with the introduction of a hydraulic rotary actuator into the design. A 3D model of the developed tilt-turning device is built in CAD KOMPAS-3D. The algorithm and the generalized method for calculating of the rotary hydraulic cylinder are presented. It is based on the results of calculations the dependence of the value of the mean thread diameter on the axial force and the value of the angle of climb of the screw thread line from the thread step and the number of turns, allowing to choose the best thread parameters

多功能综合体倾斜翻转装置的设计与研究进展

本文提出了在轮式挖掘机的基础上，采用组合式冲程机械进行铁路轨道维修和养护的概念。当前的轨道维护包括对轨道结构和轨道设备的状况进行系统的监督，并对其进行维护，以保证列车的安全运行。它是基于使用公路轨道车辆的便利性和使用倾斜转向装置进行各种类型的工作，如提升和矫直轨道，更换轨枕，铺设道砟，清除铁路轨道上的积雪等等。将液压回转作动器引入倾转装置的设计中，形成了一种具有发展前景的国产倾转装置设计方案。在CAD KOMPAS-3D中建立了倾转装置的三维模型。给出了旋转液压缸的计算算法和广义计算方法。它是根据计算结果，平均螺纹直径的值对轴向力的依赖关系和螺纹线从螺纹步长和匝数的爬升角的值，允许选择最佳的螺纹参数
