Problems solved by technology

[0004] However, this type of axle load scale has high requirements on the smoothness of the road surface. When the road surface is uneven due to various factors, it will cause the high-speed vehicle to jump violently, resulting in an error out of tolerance
In addition, due to the lack of redundancy of this type of axle load scale, it is difficult to deeply study and judge the confidence level of suspicious weighing data, which brings certain confusion to law enforcement.

Abstract

The invention discloses an array-type high-speed dynamic axle load scale, which comprises a frame body, a bearing beam and a plurality of weighing platforms. The frame body is disposed in a pavement foundation pit, and is a rack body used for increasing the compressive strength of a concrete foundation. The bearing beam is arranged on the frame body, is connected with the frame body into a whole, and is a connecting bearing body for realizing high-speed dynamic weighing. The weighing platforms are arranged on the bearing beam in an array mode in the advancing direction of a vehicle to achieve high-speed dynamic weighing, and the weighing platforms arranged in the array mode are arranged at intervals; and the plurality of weighing platforms form an equivalent long table top collaborative weighing body at intervals. According to the array type high-speed dynamic axle load scale, the weighing platforms are arranged on the bearing beam in an array mode, the weighing platforms are arranged at intervals to form an equivalent long platform surface for cooperative weighing, it is guaranteed that axle groups of a vehicle are located on the same plane, axle load stress changes of the vehicle caused by uneven road surfaces are effectively overcome, and the weighing accuracy is remarkably improved. The scale is reasonable in structural design, reliable in operation, low in maintenance rate and long in service life.

Description

technical field [0001] The invention relates to the technical field of automatic scales for dynamic road vehicles, in particular to an array type high-speed dynamic axle load scale. Background technique [0002] In recent years, in order to control vehicle overload, protect the safety of highway bridges and reduce traffic accidents, it is necessary to weigh and detect the load of high-speed vehicles. [0003] Chinese patent literature (announcement date: April 10, 2020, announcement number: CN210293410U) discloses a high-speed dynamic axle load scale, which integrates the strain beam and the load carrier without a limit device, and can be well adapted to the vehicle high-speed driving requirements. [0004] However, this type of axle load scale has high requirements on the smoothness of the road surface. When the road surface is uneven due to various factors, it will cause the high-speed vehicle to jump violently, resulting in an error out of tolerance. In addition, due to...
