Intelligent road and bridge construction warning device and system

Abstract

The invention discloses an intelligent road and bridge construction warning device and system, and belongs to the technical field of road and bridge construction. The device comprises: a lifting table, wherein a supporting plate hinged to the lifting table through a hinge shaft is arranged on one side of the lifting table; an angle adjustment mechanism; a warning mechanism; and two supporting legs, wherein the top of each supporting leg is provided with a sliding stand column in sliding fit with the supporting leg, and a height adjusting mechanism is arranged between the two sliding stand columns. The warning mechanism comprises a double-section electric push rod and a plurality of installation rings, the double-section electric push rod is sleeved with the installation rings, the installation rings are connected through ropes, the double-section electric push rod is divided into a first-stage push rod body and a second-stage push rod body, and each installation ring is provided with astrip-shaped warning strip. When the warning device works, the strip-shaped warning strips can be in an unfolded state so as to warn vehicles on a road, warning words can be projected to the road through a projector, and the windward area of the warning device can be reduced when the wind speed is high so as to reduce damage of typhoons to the warning device.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a smart road and bridge construction warning device and a system thereof. Background technique [0002] With the vigorous development of the transportation industry, the number of high-grade highways mainly including expressways and first-class highways has increased year by year, and my country's highway industry has entered a new stage focusing on the construction of high-grade highways. High-grade highways should pay special attention to the design of the linear shape, maintain the continuity of the linear shape, and make passengers feel safe and comfortable physically and psychologically. [0003] Citation publication number is that CN207091959U discloses a kind of safety warning device for road and bridge construction, and its structure comprises No. It is fixedly welded on the top of the telescopic device. There are two long support rods which are para...

Problems solved by technology

[0004] However, the above-mentioned devices all use buzzers or warning signs to remind and play a warning role. They are generally placed on the side of the road for warning, and passing vehicles cannot see the warning signs in time, and the warning effect is relatively poor. It brings a lot of trouble, and the existing warning device does not have windproof operation, and it is easy to overturn under the typhoon, which affects the normal warning operation of the warning device
