Abstract

The invention discloses a foldable guardrail device. The foldable guardrail device comprises a long-strip-shaped support, a base plate, a rotating arm, a first connecting part, a second connecting part, a first guardrail and a second guardrail. The long-strip-shaped support is provided with a shaft sleeve and a rotating shaft. The axis of the shaft sleeve extends in the horizontal direction. The rotating shaft is arranged at one end in the length direction of the support, and the axis of the rotating shaft extends in the vertical direction. One end of the base plate is capable of being rotated vertically after being hinged to the shaft sleeve. One end of the rotating arm is capable of being rotated horizontally after being hinged to the rotating shaft. The first connecting part is arranged at the other end of the support in the length direction and extends in the vertical direction. The second connecting part is arranged at the other end of the rotating arm and extends in the vertical direction. The first guardrail is capable of rotating horizontally after being hinged to the first connecting part. The second guardrail is capable of rotating horizontally after being hinged to the second connecting part. In this way, the foldable guardrail device can be upfolded when not in use and can be folded when not in use, so that the space is saved.

Description

technical field [0001] The invention relates to a foldable protective fence device, which is especially suitable for being installed on construction machinery vehicles. Background technique [0002] In the prior art, the guardrail device generally suitable for installation on construction machinery vehicles is non-foldable, that is, the fixed guardrail device. [0003] However, in some narrow working environments such as mines, after using a construction machinery vehicle equipped with a fixed guardrail device for maintenance, oil filling, etc., the guardrail device cannot be folded, which may make the narrow space unacceptable. to full use. Contents of the invention [0004] In order to solve the above problems, the present invention provides a foldable guardrail device that can be unfolded when needed and folded when not needed to save space. [0005] In order to achieve the above object, a folding guardrail device of the present invention is characterized in that: ...
