Whole vehicle dynamic truck scale with road surface

Abstract

The present invention discloses a whole vehicle dynamic truck scale with a road surface to realize the accurate separation and dynamic weighing of multiple vehicles and different types of vehicles and improve weighing precision. The technical scheme is that according to the whole vehicle dynamic truck scale with a road surface, a foundation is horizontally arranged in the ground, a scale body is on the foundation, a weighing sensor base is fixedly arranged on the foundation, a weighing sensor is arranged at the upper end of the weighing sensor base, the weighing sensor is perpendicular to the horizontal plane, the lower end of a weighing sensor bracket is arranged on the weighing sensor, the upper end of the weighing sensor bracket is matched and connected to the lower end of a scale body assembly, an axle identifier is arranged on the scale assembly and the upper end face of the axle identifier is level with the upper end face of the scale body assembly, separators are arranged at two ends of the scale assembly, and the electrical signals collected by the weighing sensor, the axle identifier and the separator are transmitted to the electronic weighing instrument in a control cabinet. The whole vehicle dynamic truck scale is widely applied to the field of dynamic weighing.

Description

technical field [0001] The invention relates to a road-mounted vehicle-type dynamic truck scale, which belongs to the technical field of dynamic weighing. Background technique [0002] At present, the expressway toll-by-weight system generally adopts the vehicle-type dynamic weighing system. This system has four main advantages: 1. It can pass vehicles continuously with high efficiency, reduce congestion, and improve traffic efficiency. 2. High-precision dynamic weighing can avoid charging disputes and improve economic benefits. 3. Effectively prevent irregular driving of vehicles and prevent tax evasion by freight vehicles. 4. The advanced system design ensures the high stability of the equipment. [0003] However, the dynamic truck scales of the vehicle-based toll collection system are all installed horizontally, the load cell is installed horizontally, and the weighing platform is also installed horizontally, and the load cell must be installed horizontally to ensure th...

AI Technical Summary

Problems solved by technology

If the road surface of the toll station is not level, the weighing platform must be installed horizontally. This method requires a large amount of engineering to absorb the slope, prolongs the installation time of the system, delays the use of the toll station, and causes a lot of inconvenience to the toll station; From the perspective of environmental protection, this practice does not conform to the construction of ecological civilization, and wastes a lot of land resources, which in turn increases difficulties and investment costs for the construction team. At the same time, this practice affects the appearance of the toll station

Moreover, GB / T7732-2008 "Fixed Electronic Weighing Apparatus" and GB / T21296-2007 "Dynamic Automatic Weighing Apparatus for Road Vehicles" did not propose that the installation method of the truck scale platform must be horizontal installation.
