Multifunctional road bridge height limiting device

Abstract

The invention discloses a multifunctional road and bridge height limiting device, which comprises a height limiting frame, a height measuring frame and a deceleration belt. The lower ends of the height limiting frame and the height measuring frame are both provided with a diagonal support frame, and the upper end of the height limiting frame is provided with a support frame. , the support frame is provided with a solar power generation device, the lower side of the support frame is provided with a number of lighting lamps, the lower end of the lighting lamp is provided with a display screen 1, and the upper end of the height measuring frame is provided with a solar power generation device, the The lower end of the solar power generating device is provided with a display screen two and a display screen three. When the vehicle passes through the device, it first decelerates through the deceleration belt, and then passes through the height measuring frame. The infrared transmitter and infrared receiver are always in the state of transmitting and receiving. When the vehicle passes through the height measuring frame higher than the specified height, the infrared receiver cannot receive infrared rays. At this time, the alarm will sound an alarm to warn the driver to prevent traffic accidents caused by hitting the height limit pole.

Description

technical field [0001] The invention relates to a height limiting device, in particular to a multifunctional height limiting device for roads and bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. Generally, bridges have a specified load-carrying weight and a limited vehicle height, which are used to protect the bridge for long-term use. Height limit devices are generally used in bridges, tunnels and other places where the height of vehicles is limited. Its function is to prevent the passage of super-high vehicles, thereby avoiding damage to bridges and tunnels. [0003] The function of the traditional height limit device is relati...

Problems solved by technology

[0003] The function of the traditional height limit device is relatively single. Sometimes the driver underestimates the height of his own vehicle, which will cause the top of the vehicle to scratch the height limit device, causing damage to the vehicle or goods, and even casualties in severe cases; at night, driving Due to various reasons, the driver often cannot pay attention to the height limit device in time, causing accidental injury; and the existing height limit device lacks the height measurement function and the alarm function, and cannot give the driver a good warning, which will cause the height limit pole to be hit. When the high pole is broken, it may fall and cause secondary damage
