Intelligent system for height limitation and traffic restriction of municipal bridge

Abstract

The invention relates to the technical field of municipal construction equipment, in particular to an intelligent system for height limitation and traffic restriction of a municipal bridge. The intelligent system comprises a detection assembly, a warning assembly and an intercepting assembly which are sequentially arranged in the advancing direction of a road and controlled by an external controller, wherein the detection assembly comprises a first base, a supporting rod, a transverse rod, a displayer, a set of distance measuring devices and a set of first cameras, the displayer is located on the side, opposite to the forward direction of the road, of the transverse rod, the emission directions of the distance measuring assemblies directly face the ground, and the shooting directions of the first cameras are opposite to the advancing direction of the road; the warning assembly comprises a second base, an electric control telescopic rod, a cross beam, a set of display screens, a set of second cameras and a set of movable plates; and the intercepting assembly comprises a soft intercepting assembly and a hard intercepting assembly which are sequentially arranged in the advancing direction of the road. The intelligent system can effectively overcome the problems that an application scope is narrow, service life is short, and the traffic control effect is poor in the prior art.

Description

technical field [0001] The invention relates to the technical field of municipal construction equipment, in particular to an intelligent system for height and row limit of municipal bridges. Background technique [0002] Municipal bridges refer to bridges built on rivers, roads and road overpasses, road overpasses over railways and pedestrian bridges within the city limits. High vehicles cause damage to bridges. [0003] In the patent document with the application number: CN202021916072.8, a municipal bridge height limiting device is disclosed, which relates to the field of municipal construction equipment, including supporting columns. There are two supporting columns, and the two supporting columns are symmetrically distributed left and right , the lower ends of the two support columns are provided with fixed columns, and the fixed columns are located below the ground surface, a main beam is arranged between the two support columns, and a solar generator is fixedly instal...

AI Technical Summary

Problems solved by technology

[0005] First, the scope of application is narrow. The height of the traditional intelligent bridge building height limit bar cannot be adjusted. Due to different road conditions, the height limit bar will also have certain variability, resulting in poor applicability during use.

[0006] Second, the service life is low, because the limit rod will collide with the vehicle. Although the spring is used to reduce the impact damage of the height limit rod, the height limit rod will still be damaged as the number of collisions increases.

[0007] Third, the traffic restriction effect is not good, because it cannot effectively intercept those super high vehicles
