Description

Technical Field

[0001] The utility model relates to the technical field of dynamic weighing, in particular to a load-bearing vehicle dynamic weighing device. Background Art

[0002] Dynamic weighing devices are widely used in weight-based charging, overload detection and other applications, and play an important role in traffic management, overload management and import and export supervision. Current weighing devices include static weighing devices and dynamic weighing devices. Dynamic weighing devices usually consist of a bearing body and a sensor. The bearing body is installed in a groove on the road foundation to carry all or part of the vehicle weight and transfer the weight it carries to the sensor; the sensor is set under the bearing body to convert the force into an electrical signal.

[0003] When a dynamically moving vehicle passes a weighing platform equipped with sensors, the sensors sense the pressure signals of the dynamic vehicle, which are then analyzed and processed by the processor, and finally the dynamic weighing value of the vehicle is calculated.

[0004] At present, the weighing device installed in the groove of the pavement foundation has a gap reserved between the bearing body and the inner wall of the groove of the pavement foundation in order to prevent the weight of the bearing body from being transferred to the pavement. However, the reserved gap causes water or mud and other objects to enter the bottom of the bearing body and gradually accumulate, bearing part of the pressure that should be borne by the sensor, resulting in inaccurate weighing.
