Road and bridge protective height limiting mechanism

Abstract

The invention discloses a road and bridge protection height limiting mechanism. The mechanism comprises limiting upright columns, electromagnetic baffles and detection upright columns, a solar panel is installed on the tops of the limiting upright columns, and the lower end of the solar panel is provided with electronic monitors; flashlights are installed on the two sides of the electronic monitors, and a display screen is installed at the lower ends of the flashlights and the lower ends of the electronic monitors; servo motors are installed at the lower left end and the lower right end of the display screen, driving rods are installed at the outer ends of the servo motors, steel wire ropes are wound on the driving rods, and the lower ends of the steel wire ropes are connected with a limiting stop rod; the electromagnetic baffles are arranged inside the limiting upright columns, and a photoelectric sensor and a reflection plate are arranged on the inner sides of the upper ends of the detection upright columns respectively. The road and bridge protection height limiting mechanism is used for carrying out height detection on vehicles by utilizing the height-adjustable photoelectric sensor, when the vehicles are ultrahigh, the limiting stop rod is used for blocking a road to prevent the vehicles from passing, and accordingly the vehicles are prevented from being collided with a height-limiting rod.

Description

technical field [0001] The invention relates to the technical field of roads and bridges, in particular to a protective height limiting mechanism for roads and bridges. Background technique [0002] Height-limiting poles can better ensure traffic safety, and play a good role in preventing vehicles from being over-height and protecting road and bridge facilities. Vehicles and height-limiting poles were damaged, which also affected traffic. The reason is that the traditional height limit pole has a single function and cannot be detected and warned in advance, resulting in the driver not observing carefully or erroneously estimating the height of the vehicle, which often leads to accidents. [0003] In addition, when the existing height-limiting pole is used to limit the height of an ultra-high earthwork vehicle, due to the accumulation of earthwork, the driver thinks that he can walk together, which will cause the height-limiting pole to scrape off the earthwork, pollute the ...
