散枕装置是CRTSⅠ型双块式无砟轨道施工专用设备之一。该文在介绍了散枕装置的主要结构基础上,着重研究设计了其液压系统以实现抓取、旋转、散布双块式轨枕的各种动作,控制其回转起动与制动的平稳性、散枕的同步性以及松枕时的限速锁紧,并对伸缩液压缸、夹持液压缸的行程进行计算,最终实现布枕操控灵活、定位准确和安全防护的目的。
The pillow device is one of CRTS Ⅰ double-block ballastless track construction special equipment. Based on the introduction of the main structure of the pillow device, this paper focuses on the design of its hydraulic system in order to grasp, rotate and distribute the various actions of the two-piece sleeper and control the stability of the swing start and brake. The synchronization of the pillow and the speed limit locking of the pine pillow, and the calculation of the stroke of the telescopic cylinder and the clamping hydraulic cylinder, finally realizing the purpose of flexible control, accurate positioning and safety protection of the pillow.
