Method for measuring shape of material pile after material-taking in contact form

Abstract

The invention discloses a method for measuring shape of a material pile after material-taking in a contact form. The method comprises the following steps: before firstly obtaining a shape data of a to-be-measured material pile, at least taking material for one time from the whole top surface of the material pile by using an arm type bucket-wheel material-taking machine, thereby generating three-dimensional data of the shape of the remained material pile; while calculating the shape of the material pile after the subsequent material-taking, updating the three-dimensional data on the surface of the material pile in the material-taking position; and while material-taking, measuring the shape of the material pile. The measurement is performed while the material is taken; the measurement is quick; the instantaneity is strong; the contact type measurement is adopted and the measurement is free from influence of external environment; the measuring accuracy is high; and the application prospect is excellent.

Description

technical field [0001] The invention relates to the technical field of stockpile shape measurement, in particular to a method for realizing contact-type real-time measurement of the remaining stockpile shape after reclaiming by using an arm-type bucket wheel reclaimer. Background technique [0002] Most of the raw materials stacked in the large-scale raw material yards of metallurgical, chemical, and thermal power plants are bulk materials, such as iron ore, coke, lime, etc., and the bulk materials (solid materials or powder materials) fall freely from the material conveying device The conical stockpile formed on the stockyard, the stockpile slope is formed by natural collapse, and the shape of the stockpile is always in a dynamic change during the production process (that is, after taking the material). Most enterprises still use traditional engineering measurement methods to complete inventory settlement and dynamic management of stockpiles. This manual cross-section meas...

AI Technical Summary

Problems solved by technology

The non-contact method of measuring the shape of the stockpile based on laser, ultrasonic and other technologies, the first choice must be to scan and measure the entire stockpile completely, and then the three-dimensional coordinate data of the surface of the stockpile can be obtained. The single measurement time is long, and the larger the stockpile is measured longer time

In addition, from the aspect of cost, enterprises generally do not provide separate traveling machinery for measuring equipment. Usually, measuring equipment is installed on the stacking and reclaiming equipment and moves with the operating equipment. Therefore, when measuring the shape of the stockpile , the stacking and reclaiming operations must be interrupted; during the stacking and reclaiming operations, the measurement of the shape of the stockpile cannot be performed, resulting in the shape measurement of the stockpile becoming an obstacle to further increase the operation rate of the stockpile and reclaiming, because the measurement of the shape of the stockpile cannot be improved frequency, let alone rapid and real-time measurement of the stockpile shape

[0006] Therefore, in summary, when the fast and real-time requirements are put forward for the measurement of the shape of the stockpile, the method based on the current measurement technology cannot meet the relevant requirements in actual use.
