Embodiment 1

[0062] As shown in Figure 1, for the electronic truck scale weighing platform with four supporting points on a rigid body, that is, a weighing platform with one section, a diagonal (point a--point d) pad virtual method is used, including the following steps:

[0063] ① After the normal installation of large electronic truck scales, use non-standard weights for calibration,

[0064] 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,

[0065] ③ A, B and P 1 To compare, C, D and P 2 Compare,

[0066] 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 of poin...

Embodiment 2

[0068] As shown in Figure 2, for the hinged six-support point electronic truck weighing platform, that is, the two-section weighing platform, a single V-type (point b-point c-point f) or an angle type (point b-point c --e point) pad virtual method, comprises the following steps:

[0069] ① After the normal installation of large electronic truck scales, use non-standard weights for calibration,

[0070] ② From the weighing instrument of this large-scale electronic truck scale, the load-bearing values ​​of each support point a, b, c, d, e, f are called A, B, C, D, E, F respectively, and the corresponding Average load-bearing value of adjacent two support points: P 1 =(A+B) / 2,P 2 =(C+D) / 2,P 3=(E+F) / 2,

[0071] ③ A, B and P 1 To compare, C, D and P 2 To compare, E, F and P 3 Compare,

[0072] ④ The plan for padding is: pad the fulcrum whose height is less than the average point load-bearing value, so that the point load-bearing value reaches the average point load-bearing ...

Embodiment 3

[0077] As shown in Figure 3, for the hinged eight-point electronic truck weighing platform, that is, the three-section conjoined weighing platform, double V-type (b point-c-point-f-point-g point) or Z-type (b-point- -d point--e point--g point) or trapezoid (b point-c point-e point-h point) or spoon type (a point-d point-e point-g point) The padding method includes the following steps:

[0078] ① After the normal installation of large electronic truck scales, use non-standard weights for calibration,

[0079] ② From the weighing instrument of this large-scale electronic truck scale, the load-bearing values ​​of each supporting point a, b, c, d, e, f, g, and h are respectively A, B, C, D, E, and F , G, H, calculate the average point load-bearing value of two adjacent support points: P 1 =(A+B) / 2,P 2 =(C+D) / 2,P 3 =(E+F) / 2,P 4 =(G+H) / 2,

[0080] ③ A, B and P 1 To compare, C, D and P 2 To compare, E, F and P 3 To compare, G, H and P 4 Compare,

[0081] ④ The plan for pad...

Abstract

A method for equalizing load-carry on each support of large-capacity electronic automobile scale includes carrying out calibration on erected scale by standard and non-standard weights, calling on load-carry value of each support from analog and digital instruments on said scale under normal weighing state, calculating out average point load-carry value of two adjacent supports, comparing load-carry value of each support with said average point load-carry value and applying rising-falling means to regulate load-carry value of each support to be on its average point load-carry value.

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...
