Abstract

A vehicle overloading detecting system comprises a frame, a front support, a back support, a steel plate spring and a vehicle axle. A height sensor is arranged between the vehicle axle and the frame and is provided with a casing, a rotation shaft, two photoelectric couplers, a blanking disc, a connecting rod and a pull rod. The blanking disc is located in the casing and fixed on the rotation shaft, light transmitting grooves at different intervals and with different lengths are arranged on the blanking disc, the two photoelectric couplers which form an angle of 180 degrees are fixed on the casing, the blanking disc rotates, a sensor support is fixed on the vehicle axle, the lower end of the pull rod is hinged to the sensor support, the upper end of the pull rod is hinged to one end of the connecting rod, and the other end of the connecting rod is connected onto the rotation shaft. The height sensor used by the vehicle overloading detecting system is designed according to specific vehicle type, and overloading situations of a vehicle can be judged by detecting the distance between the frame and the vehicle axle when the vehicle is still. The vehicle overloading detecting system has the advantages of being simple in structure, convenient to assemble, safe and reliable, durable in use and the like, and can effectively detect overloaded vehicles.

Description

technical field [0001] The invention relates to a vehicle overload detection system. Background technique [0002] Vehicle overloading is very harmful. It will not only seriously damage road and bridge facilities, increase road and bridge maintenance costs, and shorten the service life of road and bridge; Or increase the loss of road traffic accidents. Traditional vehicle weighing methods mainly include static measurement and dynamic measurement. Static measurement is to statically weigh the weight of the vehicle through a fixed electronic platform scale. The data obtained is accurate and reliable, but its measurement efficiency is low, the structure is heavy, it is inconvenient to install and carry, and it is easy to induce traffic accidents, and there are phenomena of overloaded vehicles evading inspection. The dynamic measurement mainly uses the axle load meter and the bridge strain to detect the weight of the vehicle. The axle load meter is widely used in the weight to...
