Protection device for vehicle-mounted weighing sensor

Abstract

The invention discloses a protection device for a vehicle-mounted weighing sensor. The protection device comprises a limiting rack, a base, a metal cushion plate and at least one roller, wherein the limiting rack comprises a limiting frame at the top and supporting plates on two sides, the limiting frame is used for horizontally limiting the rollers, and the supporting plates on the two sides are fixedly connected with two ends of the base respectively; the vehicle-mounted weighing sensor is arranged between the limiting rack and the base and fixedly connected with the base; a boss is arranged at the top of the vehicle-mounted weighing sensor, the metal cushion plate is fixedly arranged on the upper surface of the boss, the bottom of each roller is in contact with the upper surface of the metal cushion plate, and the top of the roller protrudes out of the limiting frame of the limiting rack. According to the protection device, the rollers are adopted for converting relatively small horizontal sliding displacement between a compartment and a vehicle frame into rolling displacement to eliminate the influence of horizontal force on the weighing sensor.

Description

technical field [0001] The invention belongs to the technical field of sensor protection devices, in particular to a vehicle-mounted load cell protection device that can effectively eliminate the influence of horizontal displacement on sensors. Background technique [0002] In recent years, the phenomenon of overloading of road transport vehicles in my country is very common, which has caused great harm to the service life of vehicles, road life, traffic safety, transportation market and vehicle production order. Therefore, it is necessary to have a practical and feasible vehicle load detection method to effectively Control vehicle overload. [0003] The current vehicle weighing devices mainly include fixed and portable. The fixed weighing devices (such as electronic scales) need to drive the vehicle onto the weighing platform, which not only has low efficiency and affects the smooth flow of the road, but also has a large structure and heavy weight. , cannot be carried, and ...
