Background
According to the regulations of railway freight loading and reinforcing rules, the allowable safety limit value of the center of gravity of the freight train deviating from the longitudinal center line of the vehicle is limited, the maximum axle weight of the railway vehicle is allowed to be 23t, and the occurrence of the safety accidents of vehicle oversteering and overloading is avoided by detecting the oversteering load. In order to effectively enhance the safety and control the safety of the freight passing through the port and the railway, the overweight and unbalanced loading conditions of the trains used for the freight passing through the port and the railway need to be detected, so that the data of overweight values, unbalanced loading, gravity center transfer and the like of each section of truck are kept in a specified range.
The existing railway main line overload and unbalance loading method adopts a gravel bed foundation of a special steel sleeper or a special cement sleeper (a sensor mounting base special for overload and unbalance loading is prefabricated on the upper surface of the special sleeper), focuses on solving the construction time of a railway main line blocking line, and achieves the purpose of quick construction. However, under the action of the wheels, the special steel sleepers or the special cement sleepers and the sensors which are arranged on the gravel bed foundation bounce along with the waves, and the ultra-unbalanced load detection and weighing metering accuracy of the system is low due to the fact that the gravel bed foundation is loose and large in size and poor in foundation stability. In order to improve the accuracy of the system, the number of the weighing units is increased, and repeated collection or measurement is carried out for many times; and by increasing the sampling rate of the wheel weight. The base of the gravel bed is affected by the vibration and impact of the train and the sun and rain, so that the special steel sleepers (special cement sleepers) have uneven loosening and sinking phenomena. Under the action of the same wheel weight, the load borne by the sleepers and the sensors at higher positions is increased; and the load borne by the crossties and the sensors at lower positions is reduced, even reverse stress occurs, so that the fluctuation (discreteness) difference of the sampling data of the system is large, and the accuracy is greatly reduced or misaligned.
