Abstract

The invention discloses a warning device for road engineering construction, and the warning device comprises two supporting blocks, wherein a driving cavity with a right opening is arranged in the supporting block on the left side, a driven cavity with a left opening is arranged in the supporting block on the right side, a driving mechanism for driving the device to operate is arranged in the driving cavity, a moving cavity with a right end wall communicating with an external space is arranged in the lower end wall of the driving cavity, a moving mechanism for controlling the supporting blockon the right side to move left and right is arranged in the moving cavity, the upper end wall of the moving cavity communicates with the driving cavity, the moving mechanism comprises a moving plate with the upper end positioned in the driving cavity, a first connecting rod is fixed on the right end surface of the lower end of the moving plate, when the device works, the device can be divided intotwo parts according to needs, so that warning boards can face two directions to provide warning information for more vehicles or pedestrians, and when the device is not needed to work, the device canbe moved by pushing, and the warning device is convenient to transfer and collect.

Description

technical field [0001] The invention relates to the field of road warning, in particular to a warning device for road engineering construction. Background technique [0002] When constructing on the road, the construction unit usually places warning signs on the road to provide warning information for passing vehicles and pedestrians; [0003] At this stage, most warning signs can only face in one direction for warning. When warning information needs to be provided in multiple directions, multiple warning signs need to be used, which increases the cost of warning, and most of them need to be carried by people when moving the warning signs. The warning sign moves, which is very inconvenient and inefficient. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a warning device for road construction, which overcomes the problems that the warning signs are not changed and one warning sign can only provide warning informa...
