Pneumatic bridge overweight prevention alarm mechanism

Abstract

The invention discloses a pneumatic bridge overweight prevention alarm mechanism that comprises a mounting groove dug in the ground; a buffer air bag is mounted in the mounting groove, a bearing platematched with the mounting groove is fixedly arranged on the upper surface of the buffer air bag; a warning table is fixedly connected to the side, located at the front end of the mounting groove, ofthe ground; a warning lamp is fixedly mounted at the upper end of the warning table, and a cavity is vertically formed in the warning table. Transmission is conducted through the gas exhaust amount inthe buffer air bag when the load-bearing vehicle presses the bearing plate downwards, the warning lamp is used for monitoring and reminding the weight of the large load-bearing vehicle one by one, sodamage to a bridge due to the fact that an overweight vehicle forcibly climbs on the bridge can be effectively prevented, and the bridge structure is protected; the electric power of the warning lampcomes from the pressure effect of the weight of the vehicle on the bearing plate and the buffer air bag, an electric power system does not need to be installed, energy is saved, manpower and an intelligent system are not needed for control, the maintenance cost is lower, the influence on traffic is small, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of bridge safety, in particular to a pneumatic bridge anti-overweight alarm mechanism. Background technique [0002] With the development of our country's transportation, the health and maintenance of bridges are increasingly concerned by people. Each bridge is designed to limit the maximum weight of a single vehicle on the bridge, and the damage to the bridge caused by overweight passenger vehicles on the bridge is the primary problem affecting the health and service life of the bridge. The light ones cause internal damage to the bridge body, and the heavy ones Otherwise, it will lead to the collapse of the bridge, causing great economic losses and casualties. [0003] Due to the high cost of installation and maintenance of the existing bridge safety monitoring system, most bridges do not have an overweight detection mechanism, which also makes it difficult for many heavy-duty vehicles to determine whether...

Problems solved by technology

Each bridge is designed to limit the maximum weight of a single vehicle on the bridge, and the damage to the bridge caused by overweight passenger vehicles on the bridge is the primary problem affecting the health and service life of the bridge. The light ones cause internal damage to the bridge body, and the heavy ones Otherwise, it will lead to the collapse of the bridge, causing major economic losses and casualties

[0003] Due to the high cost of installation and maintenance of the existing bridge safety monitoring system, most bridges do not have an overweight detection mechanism, which also makes it difficult for many heavy-duty vehicles to determine whether they are overweight when they are on the bridge, which is easy to cause damage to the bridge and cause Security risks
