Embodiment 1

[0063] like figure 1 As shown, for the electronic truck scale weighing platform with four supporting points of the rigid body, that is, a weighing platform of one section, the diagonal (point a--point d) pad virtual method is adopted, including the following steps:

[0064] ① After the normal installation of large electronic truck scales, use non-standard weights for calibration,

[0065] ② From the weighing instrument of this large-scale electronic truck scale, the load-bearing values ​​of each support point a, b, c, and d are called A, B, C, and D respectively, and the average point of two adjacent support points is calculated. Bearing value: P 1 =(A+B) / 2,P 2 =(C+D) / 2,

[0066] ③ A, B and P 1 To compare, C, D and P 2 Compare,

[0067] ④ The plan for padding is as follows: the padding height is lower than the support point of the average point load-bearing value, so that the point load-bearing value reaches the average point load-bearing value: if the load-bearing value...

Abstract

The invention relates to the technical field of installation and debugging of large electronic truck scales, in particular to a support point load-bearing equalization method in the installation and debugging process of large electronic truck scales, which is used to solve the uneven force of sensor support points during the installation and debugging process of large electronic truck scales. The problem includes the following steps: 1) According to the structural characteristics of the truck scale, it is determined to adopt the normal installation method or the step-by-step installation method. After the installation is completed, it is calibrated with a non-standard weight or a standard weight. Call out the point load-bearing value of each support point in the analog instrument or digital instrument of the balance, calculate the average point load-bearing value of two adjacent support points, 3) compare the point-bearing value of each support point with its average point load-bearing value, 4 ) According to the comparison results, draw up a virtual plan, and use the lifting method to adjust the point load-bearing value of each support point to its average point load-bearing value. Practical tests prove that the invention has good effects and is suitable for various types of large electronic truck scales to successfully complete the debugging work.

Description

technical field [0001] The invention relates to the technical field of installation and debugging of large electronic truck scales, in particular to a support point load-bearing equalization method in the installation and debugging process of large electronic truck scales, which is used to solve the uneven force of sensor support points during the installation and debugging process of large electronic truck scales. question. Background technique [0002] For the problems of unequal stress on the virtual and real support points of the sensor during the installation and commissioning of large electronic truck scales, most manufacturers and professionals currently use the surface level of the scale as the standard when installing and maintaining. The weighing body is a large-scale welded steel structure, and problems such as warping and arching will inevitably occur during processing. Therefore, it is difficult to achieve relative levels. On the other hand, due to the differe...
