The invention is applicable to the field of buildings, and provides a protective guard for road construction and a protective device. The protective guard comprises two groups of support members, at least one group of first telescopic assemblies, a first rotating assembly, two groups of automatic limiting assemblies and a limit releasing assembly; the first telescopic assemblies comprise two groups of first movable parts, and the two groups of first movable parts are arranged between the two groups of supporting parts in a sliding manner; the two groups of first moving parts are rotationally connected through the first rotating assembly; when the first movable parts slide to the positions farthest from or closest to the supporting parts, the automatic limiting assemblies automatically limit the first movable parts to slide; and the limit releasing assembly is used for releasing the limiting effect of the automatic limiting assemblies on the first movable parts. By arranging the first rotating assembly, the two groups of first movable parts can rotate relatively to change the size of the included angle formed between the two groups of first movable parts, and therefore the whole protective guard can be adjusted to be in different broken line shapes according to actual requirements so as to be suitable for different road construction occasions.
本发明适用于建筑领域，提供了一种道路施工用的防护栏及防护装置，该防护栏包括：两组支撑件；至少一组第一伸缩组件；第一伸缩组件包括两组第一活动件，两组第一活动件均滑动设置在两组支撑件之间；第一转动组件；两组第一活动件通过第一转动组件进行转动连接；两组自动限位组件；当第一活动件滑动至离支撑件最远处或最近处时，自动限位组件自动限制第一活动件进行滑动；解限组件，用于解除自动限位组件对第一活动件的限位作用。本发明通过设置第一转动组件，可以使两组第一活动件发生相对转动，以改变两组第一活动件之间所形成的夹角大小，从而可以根据实际需求将整个防护栏调整成不同的折线形状，以适用于不同的道路施工场合。
