[0039] The working process of the railway container overloading detection calibration device is as follows:

[0040] The operator completes the customization and processing of container 1, vertical traveling system, vertical walking module 3, horizontal walking module 4, lifting module 5 and electrical control module. After assembly, counterweight adjustment boxes are configured at the four corners of container 1.

[0041] Turn on the 220V power supply, use the remote controller to control the gantry crane type hoisting equipment to carry out weight 2 lifting, and sequentially place 10 2t weights, 2 1t weights and 2 0.5t weights into container 1 according to the weight layout diagram and weight number.

[0042] After the weights are lifted and arranged, the railway container overloading detection calibration device is accurately placed on the four corners of the four weighing modules. According to the weight value displayed by the weighing module, the counterweight adjustment boxes in the container are counterweighted until the four corners of the standard device are balanced.

[0043] The weight group is uniformly traced to M12 level, and the container test bed is traced to M23 level. The standard device in the balanced state does not generate partial weight and partial load, and its total weight is the sum of the weight group and the mass of the container test bed. At this time, the calibration work of the railway container overloading detection device can be carried out.

[0044] The operator uses the remote controller to control the gantry crane type hoisting equipment to move the weights 2, for example, hoists and places the 1.5t weight (one 1t weight and one 0.5t weight) to the T5 position, and hoists and removes the remaining 1.5t weight (one 1t weight and one 0.5t weight) from the container 1. At this time, the total weight of the weight in the T5 position is 3.5t, the weights in the remaining T1 to T10 positions are still 2t, and the weight group is 21.5t. The calibration can be carried out according to the (15-20)t weight range interval. The 2t weights in the standard device are hoisted out in turn, and the weight group in the standard device is set to 13.5t and 5.5t respectively, so that the corresponding calibration and value traceability of the detection device (10-15)t and (5-10)t different range intervals can be carried out in turn.

[0045] Through multiple detections, the set quality, the preset load deviation value and the weight deviation value of the railway container overload detection calibration device are compared with the measurement data of the total weight, the load deviation and the weight deviation of the railway container overload detection device, so that whether the measurement data of the railway container overload detection device meets the maximum allowable error and repeatability requirements of the calibration specification is determined, thereby completing the calibration and value traceability of the railway container overload detection device.

[0046] Finally, it should be understood that the embodiments described in the specification are only used to illustrate the principles of the embodiments of the specification. Other variations can also belong to the scope of the specification. Therefore, as an example but not limitation, alternative configurations of the embodiments of the specification can be considered consistent with the teachings of the specification. Accordingly, the embodiments of the specification are not limited to the embodiments explicitly introduced and described in the specification.
