Road and bridge protector and road and bridge protection system

Abstract

The invention discloses a road and bridge protector and a road and bridge protection system, relating to a traffic road and bridge protection facility. The road and bridge protector comprises a dynamic weighing detector, a wheel retaining plate and a return plate, wherein the dynamic weighing detector comprises a bearing plate, a pedestal, weight sensing springs and stand columns; the wheel retaining plate and the return plate are arranged at the front end and the rear end of the bearing plate respectively; the stand columns are provided with driving devices to drive the upper ends of the stand columns to lift and drop so as to lift and drop the bearing plate; and one end of the return plate close to the bearing plate is pivotally connected with the bearing plate, can tilt downwards by taking the end away from the bearing plate as an axis and can tilt back upwards at a certain angle. The road and bridge protection system comprises the road and bridge protector and a forced speed-down device. The road and bridge protector has the advantages of compact and skillful structure, need of a small number of power driving devices, small power of the power driving devices, reduced manufacturing cost, less roadbed occupation, easiness and convenience in mounting, low mounting cost, automation, good effect, unattended operation and capability of being universally applicable to national highways, provincial highways and rural roads.

Description

technical field [0001] The invention relates to traffic road and bridge protection facilities, in particular to a road and bridge protector and a road and bridge protection system capable of protecting roads and bridges in good condition. Background technique [0002] The construction of roads and bridges requires a huge amount of investment. Due to the improvement of my country's comprehensive national strength, the construction of roads and bridges throughout the country has developed rapidly. However, vehicles are seriously overloaded and over-limited, which intensifies the damage of roads and bridges, and the collapse of bridges and culverts occurs from time to time, which seriously threatens the safety of people's lives and property, and causes huge social waste. Therefore, the protection of roads and bridges is imminent and urgent. [0003] A Chinese patent discloses an "intelligent road and bridge protection system" (patent number 201120013939.3), which automatically...
