摘要:
现有动车组平顶板防松脱装置主要有安全挂绳和安全挂钩两种形式。安全挂绳结构简单，安装方便，但易发生漏装和错装问题，存在安全隐患；安全挂钩原理简单，实用性强，但存在因高度尺寸过大而不适用于狭小空间安装的问题。为此，提出了一种可伸缩的防松脱安全挂锁装置，该装置不仅具有上述两种装置的优点，还能够有效防止上述两方面问题的发生，而且由于自身为伸缩装置，因此可满足目前各种型号动车组平顶板的安装要求。
Abstracts:
There are two main forms of anti-loosing device for EMU flat-top panel: safety rope and safety hook. The former is a simple structure and easy to install, but problems of omitting and install errors tend to happen and lead to safety hazards; the latter is also simple in structure with strong practicability, but the excessive height and size limit its use in smaller spaces. In this article, an adjustable locking safety padlock device is proposed, which combines the advantages of the above-mentioned two devices and can effectively prevent the problems of them. At the same time, being a telescopic device, it could meet all kinds of current EMU flat-top plate installation requirements.
