Abstract
A modular dynamic truck scale belongs to the technical field of dynamic weighing. The truck scale is formed by continuously arranging a plurality of relatively independent weighing modules in an array manner along the running direction of a vehicle, weighing sensors are arranged at four corners of the bottom of each weighing module, the length of each weighing module is 3.5m-3.7m, and the width of each weighing module is matched with the width of a lane. The modular dynamic truck scale can realize multiple times of weighing in single running of the vehicle, and finally, the average value of all the weighing is taken, so that the finally obtained weighing accuracy is improved. And when the current car does not leave the truck scale yet, the rear car can drive in, and continuous car following weighing is realized.
Description
Technical Field
The utility model belongs to the technical field of dynamic weighing, and particularly relates to a modular dynamic truck scale.
Background
Truck scales, also known as loaders, are large scales placed on the ground, commonly used to weigh the tonnage of a truck, and are the primary weighing devices used for bulk cargo metering in factories, mines, merchants, and the like. The whole-vehicle type dynamic truck scale has high weighing accuracy, is widely accepted by a highway system, but the common whole-vehicle type truck scale cannot realize continuous car following weighing, and can weigh the rear truck on the truck scale after the front truck is completely driven away, so that a large error can occur during continuous car following weighing. In addition, the weighing can be performed once after each time the automobile is weighed, and if more accurate weighing data are obtained, the automobile must be weighed again after the automobile is driven away, so that the queuing waiting time is long.
Disclosure of utility model
The utility model provides a modular dynamic truck scale, which aims to improve the accuracy of continuous car following weighing of a whole dynamic truck scale and reduce queuing waiting time.
The utility model provides a module formula developments truck scale which characterized in that: the vehicle-mounted intelligent weighing system is formed by continuously arranging a plurality of relatively independent weighing modules in an array manner along the running direction of a vehicle, wherein weighing sensors are arranged at four corners of the bottom of each weighing module, the length of each weighing module is 3.5m-3.7m, and the width of each weighing module is matched with the width of a lane.
Further, limiting devices are arranged around the weighing module.
Further, the number of the weighing modules is five.
Preferably, the length of the single weighing module is 3.6m, and the length of the whole modular dynamic truck scale is 18m.
The utility model has the beneficial effects that: six-axis front-rear wheelbase of common vehicles on roads is usually 12m-14m, when the vehicles completely drive into the modular dynamic truck scale, the first weighing is carried out when the vehicles are positioned in the front four modules, as the vehicles move forward, when the vehicles enter the rear four modules, the vehicles are subjected to secondary weighing, for shorter vehicles, the vehicles can be weighed more times, for example, four weighing opportunities can be obtained for two-axis vehicles, finally, the average value of all weighing is taken, and the finally obtained weighing accuracy is improved. And when the current car does not leave the truck scale yet, the rear car can drive in, and continuous car following weighing is realized.

Detailed Description
Example 1: the modular dynamic truck scale is formed by arranging five weighing modules 1 which are relatively independent in a continuous array along the running direction of a vehicle, wherein the length of each weighing module 1 is 3.6m, the width of each weighing module is matched with the width of a lane, weighing sensors are arranged at four corners of the bottom of each weighing module, limiting devices 2 are arranged around the weighing modules 1, and the limiting devices 2 are used for counteracting horizontal impact force generated when the vehicle runs on the weighing modules 1. The result is obtained through a large number of test tests, the length of the single weighing module 1 is 3.6m, namely, the modular dynamic truck scale factory is 18m, so that the best effect can be achieved, because the single-axle weighing in common vehicles on the highway is relatively easy, accurate weighing is key for achieving accurate weighing of vehicles through a shaft coupling, particularly a three-shaft coupling, the shaft distance of the three-shaft coupling is 2.7m, when the length of the single weighing module is 3.6m, the vehicle is driven on the truck scale for 0.9m after the three-shaft coupling is weighed, and enough weighing data can be acquired by the weighing sensor 3 in the distance of 0.9m, and the weight of the three-shaft coupling is accurately weighed. And when the vehicle continuously runs along with the vehicle, the front vehicle has a certain rear suspension distance, the rear vehicle has a certain front suspension distance, and a certain safety distance is reserved between the two vehicles, so that the condition that the rear axle of the front vehicle and the front axle of the rear vehicle are simultaneously positioned in the same weighing module can not occur.
Six-axis front-rear wheelbase of common highway vehicles is usually between 12m and 14 m. The weighing process for a six-axis vehicle is shown in fig. 3 and 4. When the vehicle completely enters the weighing platform and is positioned on the first four weighing modules 1, the system automatically fits the first four weighing modules 1 into a whole vehicle weighing system to weigh the whole vehicle; as the vehicle moves forward, when the vehicle enters the last four weighing modules 1, the system automatically fits the last four weighing modules 1 into a whole vehicle weighing system, and the vehicle is weighed for the second time. When the front wheel of the vehicle leaves the modular dynamic truck scale, the system sends a weighing result, and the sent result is the average value of the two times of weighing.
For shorter four-axis or two-axis vehicles, more weighing opportunities can be obtained on the truck scale, for example, four weighing opportunities can be obtained for two-axis vehicles, and the obtained average value is more accurate.
