Description

Technical Field

[0001] This invention relates to the field of performance testing technology for mining rock drilling tools, and in particular to a method, system, storage medium, and equipment for testing the performance of high-pressure rock drilling teeth based on noise analysis. Background Technology

[0002] In modern large-scale infrastructure construction and mineral resource extraction projects, high-pressure rock drills are widely used in rock drilling operations and are key consumables to ensure smooth construction. With the continuous expansion of project scale and the increasing complexity of construction environments, the performance requirements for high-pressure rock drills are becoming increasingly stringent. On the one hand, the large differences in rock hardness and geological conditions require the drills to maintain high rock-breaking efficiency under strong impact and high wear conditions; on the other hand, to improve construction efficiency and reduce costs, the drills need to have a long service life and high reliability.

[0003] Currently, methods for evaluating the performance of high-pressure ball teeth have significant shortcomings. Traditional testing relies primarily on manual visual inspection, judging surface wear and cracks based on experience. This is highly subjective and fails to detect subtle internal defects, making it impossible to accurately assess potential performance issues. While hardness testing reflects surface hardness, it cannot reflect the ball teeth's comprehensive performance under actual complex working conditions, such as impact resistance, wear resistance, and fatigue life. In simulated working condition testing, existing methods struggle to realistically reproduce extreme operating environments like high wind pressure, strong impacts, and variable rock characteristics, leading to significant discrepancies between test results and actual performance. Furthermore, the various evaluation methods are independent and lack systematic integration, failing to provide a comprehensive, accurate, and mutually verifiable evaluation system for ball tooth performance. This results in a lack of sufficient scientific basis for ball tooth research and development, quality control, and selection, severely hindering engineering construction efficiency and quality improvement. Therefore, there is an urgent need to develop a scientific, comprehensive, and accurate testing method for the performance of high-pressure ball teeth. Summary of the Invention

The working performance quantification function is used to calculate the working performance quantification value of the rock drilling tool to be evaluated. The working performance quantification value of the rock drilling tool to be evaluated is compared with the preset benchmark value of the benchmark rock drilling tool to quantify and evaluate the relative working performance of the rock drilling tool to be evaluated.

[0006] Furthermore, the effective tunneling noise segment is the time period during which the noise value continuously exceeds the preset noise threshold, and the number of extracted effective tunneling noise segments is consistent with the number of tunneling units corresponding to the total tunneling length.

[0007] Further, the step of identifying and extracting effective tunneling noise segments from the working noise data based on a preset noise threshold to obtain multiple effective tunneling time periods corresponding to the total tunneling length includes: The extracted multiple valid tunneling time periods were sorted and segmented by duration to obtain the frequency distribution of each time interval, and denoted as follows: , ,..., ,in, This represents the number of segments.

[0009] Furthermore, the wear efficiency function is determined by establishing a function model and fitting parameters.

[0018] The following detailed description of the embodiments will further illustrate the present invention in conjunction with the above-described accompanying drawings. Detailed Implementation

[0019] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Example 1 Please see Figure 1 The figure shows a high wind pressure rock drilling tooth performance testing method based on noise analysis in the first embodiment of the present invention. The method specifically includes steps S01-S04.

[0023] Step S01: Obtain the working noise data and corresponding total tunneling length of the benchmark rock drilling tool during its complete service life.

[0024] In practice, under the same working conditions and equipment parameters, continuous working noise data of a model A rock drill bit (hereinafter also referred to as "benchmark model rock drill tool") as a performance benchmark is collected from the start of use to complete scrapping, and its total tunneling length throughout its entire life cycle is accurately recorded. The equipment used to collect working noise data and tunneling length can be, but is not limited to, a noise data acquisition device installed at the detection position on the rock drill equipment, and an infrared rangefinder set at the rock drill opening.

[0025] Step S02: Based on a preset noise threshold, identify and extract effective tunneling noise segments from the working noise data to obtain multiple effective tunneling time periods corresponding to the total tunneling length.

[0026] In practical implementation, a noise threshold is set, such as 105 dB. From continuous noise data, all time periods where the noise intensity continuously exceeds this threshold are identified. It should be noted that, as is understood in this field, a rock drill generates such a high-noise time period for every meter it advances. Therefore, the total number of time periods identified should equal the total number of meters drilled. In other words, the effective tunneling noise segment refers to the time period where the noise value continuously exceeds the threshold. The number of these extracted segments is consistent with the number of tunneling units (e.g., "meters") corresponding to the total tunneling length, thus obtaining multiple effective tunneling time periods.

[0027] Step S03: Based on the effective tunneling time period and its distribution, construct a wear efficiency function with wear state as the independent variable, and based on the wear efficiency function and the statistical distribution of the effective tunneling time period, establish a quantitative function for the working performance of the benchmark rock drilling tool.

[0028] Step S04: Calculate the quantitative value of the working performance of the rock drilling tool to be evaluated using the working performance quantification function, and compare the quantitative value of the working performance of the rock drilling tool to be evaluated with the preset benchmark value of the benchmark rock drilling tool to quantify the relative working performance of the rock drilling tool to be evaluated.

[0029] Based on the specific implementation of steps S03 to S04, all identified high-noise time periods are sorted from shortest to longest according to their duration. Then, this ordered time series is divided into several ( (Number) consecutive time intervals, and count the number of time intervals contained in each interval, denoted as _____. , ,..., And finally, the working time distribution of the benchmark rock drilling tool under different drilling speeds (fast and slow correspond to different time lengths) was obtained; Based on the above data, a performance function for a benchmark rock drilling tool was constructed. Because the time taken by the drill bit to excavate a unit length is functionally related to the rock hardness, and the rock hardness is functionally related to the wear of the drilling teeth, the time taken by the drill bit to excavate a unit length is functionally related to the wear of the drilling teeth. Let's assume the wear coefficient for the time taken per unit length of excavation is denoted as the function... In this application, the formula is derived by setting the overall wear rate of the benchmark rock drilling tool to 1000: , For positive integers, multiple sets of data from the benchmark rock drilling tool are input. From the middle After that, multiple groups Substitute return The working performance functions of multiple benchmark rock drilling tools were obtained. Then, data from other benchmark rock drilling tools were substituted into multiple sets. In the middle, filter out Values ​​closer to 1000 function; Furthermore, regarding the specific calculation of the performance quantification function formula, an example is given to construct the performance function of a benchmark rock drilling tool. Then, let's assume the wear coefficient function is as follows: , Substitute into the formula: , It is a positive integer. The number of time periods. For the corresponding The wear coefficient of the serial number can be used to obtain the corresponding coefficient: (1) When the wear coefficient is: At that time, the working data A1 and A2 of the benchmark model rock drilling tool (regarding the working data of A1 and A2, such as...) Figure 4 Substitute the drilling data of each drill bit into the formula. We can obtain:

[0030] Find: =0.015252, =0.201385, Performance function of Model A rock drill teeth .

[0031] (2) When the wear coefficient is: At that time, substitute the working data A1 and A2 of the benchmark rock drilling tool into the formula. We can obtain:

[0032] Find: =0.345158, =-1.67962, Performance function of Model A rock drill teeth .

[0033] Input the working data of A3 rock drilling teeth , In the middle, filter those whose function values ​​are closer to 1000, such as Figure 5 As shown.

[0034] according to Figure 5 As shown, when the wear coefficient is When the function value is closer to 1000, the performance function of rock drill A is more accurate. .

[0035] Finally, the rock drilling tool of the model to be tested (abbreviated as: B rock drilling tooth) can be brought into the test room in the manner described above. The function value is obtained from And based on the benchmark model rock drilling tool and the B rock drilling tooth, data comparison was carried out; like If the value is less than 1000, the working performance of the B-type rock drill tooth is insufficient compared to the performance of the benchmark rock drill tool. like =1000, then the working performance of the B-type rock drill tooth is the same as that of the benchmark rock drill tool. like If the value is greater than 1000, then the performance of the B-type rock drill tooth is stronger than that of the benchmark rock drill tool.

[0036] In summary, the high-pressure rock drilling tooth performance testing method based on noise analysis in the above embodiments of the present invention establishes a quantitative model between "time distribution - wear function - performance constant" through noise signal analysis. This involves converting the working noise data of the high-pressure rock drilling tooth into the working time per unit length of tunneling, and defining the wear efficiency accordingly. Furthermore, it obtains various wear efficiency functions through a hypothetical method. After substitution and verification, suitable functions are selected, and then working performance functions are constructed. This method enables the quantitative characterization of the working performance of high-pressure rock drills. It overcomes the shortcomings of existing characterization methods, which are inaccurate and cannot truly reflect actual working performance. It has the advantages of strong scientificity, high accuracy, and good operability. It can provide a scientific basis for the research and development, quality control, and selection and application of high-pressure rock drills, and help improve engineering operation efficiency and reduce production costs. It solves the problem that current methods are unable to truly reproduce extreme working environments such as high wind pressure, strong impact, and variable rock characteristics, which leads to a large deviation between test results and actual working performance.
