Description

Technical Field

[0001] The utility model relates to the technical field of automobile scales, in particular to a waterproof axle group dynamic automobile scale device. Background Art

[0002] A truck scale is also called a floor scale. It is a large scale installed on the ground, usually used to weigh the tonnage of a truck's cargo. It is the main weighing equipment used by factories, mines, businesses, etc. for measuring bulk goods. Before the 1980s, common truck scales were generally mechanical truck scales with a purely mechanical structure using the principle of leverage, also called mechanical floor scales. With the development of the floor scale industry, mechanical truck scales have gradually been replaced by analog truck scales and digital truck scales that are high in accuracy, good in stability, and easy to operate.

[0003] Usually, the installation location of the electronic truck scale should have a good drainage channel, and the installation location cannot be lower than the surrounding area, otherwise the low terrain will cause water to accumulate when it rains and submerge the scale, damaging the sensor. Truck scales are mainly divided into shallow pit truck scales and pitless truck scales. Shallow pit truck scales are installed underground. After installation, the surface of the truck scale is flush with the ground. Shallow pits do not require slopes. This method is suitable for customers with smaller sites. However, if the nearby terrain is low, it is easily affected by rain. On the other hand, installing it underground is not conducive to maintenance and after-sales repairs. Pitless truck scales are installed on the ground plane. Slopes on both sides are required to facilitate getting on and off the car, and being higher than the ground is conducive to drainage, but it is limited to requiring a larger site. Therefore, it is necessary to solve the problem of truck scale waterproofing and reduce the limitations of site size. At the same time, truck scale equipment that is easy to maintain is a technical problem that needs to be solved. Utility Model Content
