Load-limiting bridge-based vehicle overweight testing and alarming system

The invention discloses a load-limiting bridge-based vehicle overweight testing and alarming system. The upper part of a groove is covered with a cover layer; a wheel-pressure testing device is arranged in the groove and comprises a pressure-bearing cap and a bracket table; a spring is arranged between the pressure-bearing cap and the bracket table; an upper contact is arranged on the pressure-bearing cap; a lower contact is arranged on the bracket table; and an alarm device is arranged outside the wheel-pressure testing device. Compared with the prior art, the load-limiting bridge-based vehicle overweight testing and alarming system has the advantages that the vehicle overweight testing and alarming system is simple in structure, small in construction difficulty, low in manufacturing cost and significant in effect, adjustment can be carried out according to the bearing capacity of different types of bridges and the bridges are effectively protected. 本发明公开了种基于限载桥梁的车辆超重测试报警系统，凹槽上部由盖层覆盖，凹槽内设有轮压测试装置，轮压测试装置包括承压帽和
