The invention provides a rail weighbridge bearing structure for realizing high-speed metering. The bearing structure is characterized in that a main frame base is laid below parallel rails, wherein the main frame base is fixed on an installation foundation, a plurality of steel base plates are arranged on the main frame base at intervals corresponding to each rail, a plurality of steel base platesare arranged at intervals along the transverse direction and are abutted against lower sides of the rails, and two ends of each steel base plate are respectively abutted against the main frame base through a pressure weighing sensor. The bearing structure is advantaged in that the enough number of pressure weighing sensors is directly installed below the rails, complex links in weight transmission are omitted, the weighing stability is improved, moreover, weight interference caused by vibration of locomotives and vehicles is reduced, and detection accuracy is improved.
Description
technical field [0001] The invention relates to a railway freight car transportation safety overload, partial load detection and weighing measurement equipment, in particular to a rail scale bearing structure for realizing high-speed measurement. Background technique [0002] With the increase of railway transportation volume and railway speed, higher and stricter requirements are put forward for the monitoring of railway transportation safety. [0003] In the safety guarantee of railway transportation, the automatic track scale plays a pivotal role. It dynamically and continuously accurately weighs and detects each truck when the railway truck does not stop and runs at high speed, and calculates the overload of the truck. , Unbalanced load information, so as to provide reliable safety guarantee for railway transportation. [0004] The bearing platform is an important part of the automatic track scale. It is installed on the foundation of the concrete track bed. It is used ...
