Description
Technical Field
[0001] The utility model relates to the field of dynamic curved track weighing pad weighing sensors, in particular to a curved α slope steel sleeper module. Background Art
[0002] Dynamic track scales are widely used in national railways and high-speed railways, as well as in railway dedicated lines of large, medium and extra-large industrial and mining enterprises such as steel, metallurgy, coking, petrochemical, energy, thermal power generation, cement and building materials, machinery manufacturing, mining, airports, ports, docks, logistics yards, transfer stations, etc., because they can realize continuous dynamic measurement of each vehicle of freight trains, passenger trains and special railway trains in the process of movement, uniform speed passage, fast measurement speed, accurate measurement, safety and reliability. They can dynamically measure the loaded materials of various rail vehicles and various special rail vehicles, accurately formulate raw materials for large-scale continuous production within working conditions enterprises, and improve the refined measurement of the quality of basic industry products, playing an important role.
[0003] However, in the prior art, most track scales use column pressure sensors. The outer rail is higher than the inner rail at the bend, and the weighed vehicle is tilted in the direction of the curvature radius. Since the weighing sensor only uses a column pressure weighing sensor structure, the specific gravity of the items loaded on the vehicle is different, and the center of gravity height is different; in addition, there is a lack of horizontal force measurement sensors for the centrifugal force and centripetal force of the vehicle on the curve. The vertical force sensor alone cannot detect the errors caused by the actual acceleration, centrifugal force and centripetal force when the vehicle turns; furthermore, the column pressure sensor installed at the curve position, when installed in a sloped position on the curve, is affected by the lateral force, which greatly reduces the technical indicators of the sensor itself, such as linearity, hysteresis, and repeatability. In addition, the previous curved track scales are of the broken rail type, which poses a greater safety hazard to vehicles traveling in the curved area. Therefore, a curved α slope steel sleeper module is proposed. Utility Model Content
