Embodiment 1

[0040] Such as Figure 1-Figure 14As shown, a liquid transfer weighing platform includes a platform base 1, the platform base 1 is installed in the foundation pit opened on the road surface, a platform cover 14 is provided above the platform base 1, and a platform cover 14 is provided between the platform base 1 and the platform cover 14. There is a liquid soft bag 5 and a hydraulic sensor 11, and a contact sensor 3 is arranged on the platform base 1, and the contact sensor 3 is used to detect whether the platform base 1 and the platform cover plate 14 are in contact.

[0041] The further optimized technical scheme of the present invention is, as figure 2 As shown, the two sides of the platform base 1 are fixedly connected with the limited square steel 2 .

[0042] The further optimized technical solution of the present invention is that two limiting square steels 2 are welded on both sides of the platform base 1 .

[0043] The further optimized technical solution of the pr...

Embodiment 21

[0054] The difference from Example 1.1 is that the liquid in the soft liquid pack 5 is used as the pressure transmission medium, and the liquid in the soft liquid pack 5 has a lower freezing point.

Embodiment 22

[0056] The difference from Embodiment 1.1 is that two sides of the platform base 1 are fixedly connected with two limit square steels 2 by bolts, such as figure 2 shown.

Abstract

The invention discloses a liquid transfer-type weighing platform, which comprises a platform base, wherein the platform base is installed in a foundation pit formed in the road surface, a platform cover plate is arranged above the platform base, a liquid soft package and hydraulic sensors are arranged between the platform base and the platform cover plate, a contact sensor is arranged on the platform base, the contact sensor is used for detecting whether the platform base is in contact with the platform cover plate, and the liquid soft package adopts a liquid as a pressure transfer medium. The liquid transfer-type weighing platform provided by the invention can complete the accurate measurement of object weight on the road surface with a certain slope by using few liquid sensors.

Description

technical field [0001] The invention belongs to the technical field of road metering, in particular, the invention relates to a liquid transfer weighing platform. Background technique [0002] A truck scale, commonly known as a truck scale, is a large-scale measuring device that checks the weight of a motor vehicle on the ground. [0003] my country's current expressway tolls for trucks are billed by dynamic weight, but the dynamic weight toll method will cause great losses to the country due to defects such as large errors and easy cheating. In order to solve this problem, many places in the country are now Gradually change the dynamic weight charging method to the static weight charging method of the whole vehicle. Since most of the static weighing equipment of the whole vehicle use about 10 column or bridge pressure sensors to collect weight parameters, the installation requirements of this type of equipment are Accuracy can only be guaranteed on level roads. However, many...
