Integral axle weight scale for road vehicle and mounting method thereof

Abstract

The invention relates to an integral axle weight scale for a road vehicle, which comprises a weighing platform, weighing sensors and a weighing meter. The weighing platform comprises a weighing platform panel, a netlike rib plate on the bottom surface of the weighing platform panel, and two longitudinal end plates; at least more than two weighing sensors are arranged on a box-shaped scale base, output signal wires of the weighing sensors after passing through a junction box are connected to the weighing meter, more than two spherical seats on the bottom surface of the weighing platform panel are pressed and jointed to the weighing sensors, and the height between the top surface of the weighing platform panel and the bottom surface of the box-shaped scale base is between 60 and 120 millimeters; a pedestal of the box-shaped scale base is provided with a drain hole, the inner peripheral wall of the box wall is provided with a sealing seat, a flexible sealing element is arranged in the sealing seat, and the weighing platform panel is hermetically connected with the box-shaped scale base through the flexible sealing element; and the box-shaped scale base and the weighing platform are provided with a link stopper for limiting the weighing platform, a longitudinal limit element, a transverse limit element and a vertical limit element. The integral axle weight scale has the characteristics of convenient installation, reliable use, low integral height and high weighing precision.

Description

technical field [0001] The invention relates to an integrated axle load scale for road vehicles and an installation method thereof, belonging to the technical field of weighing dynamic or / and static road vehicles. Background technique [0002] For the weighing toll of highways and graded highways and the weighing of over-limit detection, platform-type or curved-plate axle load scales are mainly used. At present, these two types of products are widely used, but after several years of mass promotion and application, they have also exposed obvious shortcomings. The weighing platform axle load scale adopts a standard weighing platform and a load cell structure, such as the disclosed "automobile axle load measuring device" of CN2350747Y. The box beam is composed of upper and lower surfaces and a frame in the middle. An upturning beam above the ground is fixed along both sides of the box beam. The upturning beam is integrated with the box beam and is not connected with the box be...

AI Technical Summary

Problems solved by technology

The advantages of the curved plate axle load scale are less foundation construction, shorter transformation period, and relatively less maintenance workload during use; the disadvantage is that the dynamic weighing accuracy is low, and the total weight accuracy is generally ±5% F.S., especially Poor eccentric load performance, high requirements for installation, difficult to meet the weighing accuracy requirements of road weight toll and over-limit detection
