Height-limiting early warning device for road traffic

Abstract

The invention discloses a height-limiting early warning device for road traffic, comprises a height limiting device and an early warning device, A limit beam comprises a fixed beam at both ends and acushion beam at the middle, a movable bar is arranged At that bottom of the connection between the fix beam and the support column, the movable bar is insert into the support column and a limiting plate is installed at one end of the support column, an electric telescopic bar is installed below the limiting plate in the support column, a plurality of springs assemblies are installed in parallel inside the buffer beam, and lighting tubes are symmetrically installed on both sides of the warning lamp tube; As that displacement sensor and the display lamp assembly cooperate with each other, the flicker frequency and the sound magnitude of the display lamp assembly vary with the distance between the drive vehicle and the height limiting device, and the driver can be promptly and effectively reminded of the height limiting device; When the driving vehicle intrudes into the height limiting device, the spring assembly in the cushion beam can cushion the vehicle and the height limiting device,which greatly reduces the damage degree of the vehicle and the height limiting device, and at the same time, the limit beam is lifted by the electric telescopic rod, so that the vehicle is convenientto move out.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a height limit early warning device for road traffic. Background technique [0002] With the development of society, there are more and more urban expressways, and the risks caused by super-high vehicles driving on expressways are also increasing. In order to ensure the safety of urban traffic, urban expressways generally restrict the driving of super-high vehicles. However, because the driver has not yet established a good normative traffic behavior, which leads to the occurrence of some unsafe factors, it appears that an intelligent height limit pole warning device will be set up at the entrance of the expressway; at the same time, in order to restrain the height of super high vehicles, Hang warning signs on roads or bridges, and set height-limiting mechanisms such as height-limiting viaducts not far from tunnel entrances, viaducts, flyovers, bridges, etc., to limit the he...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing height-limiting mechanism is not eye-catching and intuitive enough, and it is troublesome to drag the vehicle out and repair the equipment after the driving vehicle is stuck by the height-limiting mechanism. solve the above problems
