Abstract
Description
Technical Field
[0001] The present application relates to the technical field of equipment fault detection, and in particular to a drilling rig chain break protection method, a drilling rig chain break protection device, a computing device, and a computer-readable storage medium. Background Art
[0002] A rotary drill is a type of drilling equipment that relies on a pressurized and rotary mechanism to provide sufficiently large axial pressure and rotary torque to the drill bit through the drill pipe. The rotary drill bit drills and rotates on the rock at the same time, generating static pressure and impact dynamic pressure on the rock. The cone continuously squeezes, cuts, impacts and crushes the rock while rolling at the bottom of the hole. Compressed air with a certain pressure and flow rate is ejected from the drill bit nozzle through the inner cavity of the drill pipe, continuously blowing the rock debris from the bottom of the hole along the annular space between the drill pipe and the hole wall to the outside of the hole until a hole of the required depth is formed.
[0003] In open-pit mines, when the rotary drill is drilling, the inner side of the lifting chain may break. The broken chain passes through the crown wheel on the top of the rotary drill, and the power head may fall directly. The lifting chain will fly out directly (commonly known as: flying over the mountain), causing damage to the rotary drill parts and safety accidents such as the chain hitting people.

[0061] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific implementations disclosed below.
[0062] The terms used in one or more embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit one or more embodiments of the present application. The singular forms "a", "the" and "the" used in one or more embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used in one or more embodiments of the present application refers to and includes any or all possible combinations of one or more associated listed items.
[0063] It should be understood that although the terms "first," "second," and the like may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" may also be referred to as "second," and similarly, "second" may also be referred to as "first," without departing from the scope of one or more embodiments of the present application.
[0064] First, the terms involved in one or more embodiments of the present invention are explained.
[0065] A rotary drill is a type of drilling equipment commonly used in large open-pit mines. Over the past half century, open-pit drilling equipment has evolved from "knock drills" to flame drills and percussion (down-the-hole) drills. Ultimately, rotary drills, with their advantages of large borehole diameters and high drilling efficiency, have become the prevalent drilling equipment used in large and medium-sized open-pit mines.
[0066] This application provides a drilling rig chain break protection method, a drilling rig chain break protection device, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments.
[0067] Figure 1 A flowchart of a drilling rig chain break protection method according to an embodiment of the present application is shown, which specifically includes the following steps:
[0068] Step S102: collecting the head sheave status data of the target drilling rig in real time according to the preset sensors;
[0069] Step S104: determining the speed data of the overhead sheave according to a preset speed algorithm based on the overhead sheave state data;
[0070] Step S106: When the sheave speed data meets the preset chain break condition, a shutdown instruction and a warning instruction are generated;
[0071] Step S108: In response to the shutdown instruction, the target drilling rig stops running, and in response to the warning instruction, a preset warning device issues a chain break warning.
[0072] The target drill is a rotary drill used in open-pit mines for drilling operations. The drill uses a power head to power the drill rod. The power head moves up and down via lifting chains arranged on both sides. These lifting chains are connected to the crown sheaves on the top of the rotary drill, which can be thought of as fixed pulleys that support the lifting chains and ensure their stability during operation.
[0073] Based on this, if the hoist chain of a rotary drill breaks, the hoist chain will accelerate downward due to gravity. The sheave connected to the hoist chain will be affected by the broken hoist chain. Specifically, the friction between the broken hoist chain and the sheave will cause the sheave to rotate faster. In this case, a preset sensor monitors and collects sheave status data in real time, and calculates sheave speed data based on the detected sheave status data. When fluctuations in sheave speed data are detected and certain conditions are met, namely, a chain break condition, a determination is made that the hoist chain is broken, and a shutdown command and a warning command are generated. Based on the shutdown command, the target drilling rig's operations are halted, and based on the warning command, a preset warning device issues an alarm. It should be noted that the warning device can be one or more of a warning indicator light, a warning ringtone, and a pop-up warning message window on the human-machine interface. The type and number of warning devices are determined by the actual usage scenario and are not limited in this embodiment.
[0074] In summary, by real-time monitoring of the target drilling rig's sheave and further determining its speed, the status of the lifting chain can be determined. In the event of a broken lifting chain, the target drilling rig can be shut down immediately to reduce the loss of equipment components and avoid casualties. The early warning device can also notify people of the broken lifting chain to avoid the expansion of the impact of the safety accident, and remind relevant personnel to inspect and repair the lifting chain. The lifting chain of the drilling rig can be automatically detected, and there is no need to arrange safety officers on site to guard the equipment, which is conducive to the realization of unmanned equipment operation and the construction of intelligent mines.
[0075] Furthermore, the head sheave of the target drilling rig can be detected by the principle of electromagnetic induction. In this embodiment, the specific implementation is as follows:
[0076] A first electromagnetic component is installed on the head sheave of the target drilling rig; a second electromagnetic component is installed outside the head sheave of the target drilling rig according to a preset electromagnetic sensing distance interval; electromagnetic signal data between the second electromagnetic component and the first electromagnetic component is collected in real time by the second electromagnetic component as the head sheave status data; and the head sheave speed data of the target drilling rig is determined based on the frequency of the electromagnetic signal data.
[0077] Among them, by installing a first electromagnetic component on the sky wheel and a second electromagnetic component outside the sky wheel, and setting the installation position of the second electromagnetic component according to the electromagnetic sensing distance range, when the sky wheel rotates, electromagnetic signal data is generated between the first electromagnetic component and the second electromagnetic component due to the electromagnetic induction effect.
[0078] Based on this, since the rotation of the sky wheel drives the position of the first electromagnetic component to change, while the position of the second electromagnetic component is fixed, the distance between the first electromagnetic component and the second electromagnetic component will also change, which in turn will cause the electromagnetic signal generated between the first electromagnetic component and the second electromagnetic component to change. The installation position of the second electromagnetic component needs to ensure that the minimum distance between the first electromagnetic component and the second electromagnetic component is greater than the electromagnetic perception distance between the two. The electromagnetic perception distance means that when the distance between the first electromagnetic component and the second electromagnetic component exceeds this distance, no current signal can be generated, or the generated current signal is too weak to be collected and analyzed.
[0079] Furthermore, there are two scenarios for determining the maximum distance between the first and second electromagnetic components: a maximum distance greater than the electromagnetic sensing distance between the two components, and a maximum distance less than or equal to the electromagnetic sensing distance between the two components. In the first scenario, the overhead wheel rotates periodically, generating a periodic, non-smooth curve of electromagnetic signal data. In this scenario, the maximum value or derivative discontinuity of the electromagnetic signal data can be analyzed to determine the period and frequency of the electromagnetic signal data. Alternatively, the phase of the curve portion of the electromagnetic signal data where the derivative is continuous can be analyzed to determine the period and frequency of the electromagnetic signal data.
[0080] In the second scenario, the center wheel rotates periodically, generating a smooth, periodic electromagnetic signal. The peaks and troughs of the electromagnetic signal, or the phases of each point within the signal, can be analyzed to determine its period and frequency. By determining the frequency of the electromagnetic signal, the time required for one rotation of the center wheel can be determined, effectively determining its rotational speed.
[0081] In summary, the above method can realize low-cost determination of the overhead sheave speed data, and the data processing process is simple, without placing excessive demands on the computing power of the hardware equipment, and the data processing has good real-time performance and high accuracy of the data processing results.
[0082] Furthermore, the head sheave of the target drilling rig can be detected by a visual sensor. In this embodiment, the specific implementation is as follows:
[0083] According to the visual sensor, image frame data of the target drilling rig is collected in real time; the head sheave position change data of the target drilling rig contained in adjacent image frames in the image frame data is used as the head sheave status data; and the head sheave speed data is determined based on the head sheave position change data and the frame rate of the image frame data.
[0084] Among them, the visual sensor can be a camera sensor, a depth sensor, an infrared sensor, a photoelectric sensor, etc. The specific type of visual sensor is determined by the actual usage scenario and is not limited in this embodiment.
[0085] Based on this, a visual sensor is used to capture images of the target drilling rig. Based on the captured image frame data, image analysis technology is used to identify the head sheave contained therein and determine the position change of the head sheave between two adjacent image frames. The process of determining the head sheave position change between adjacent image frames can be performed by analyzing preset image acquisition points on the head sheave, such as preset color blocks on the head sheave or structural feature points of the head sheave itself. The specific image acquisition points are determined by the actual usage scenario and are not limited in this embodiment. After determining the head sheave position change data in two adjacent image frames, the head sheave speed data can be determined based on the image acquisition frequency of the visual sensor.
[0086] In summary, the speed of the overhead wheel is collected by the visual sensor, and the collected images have high accuracy. In addition, the calculation granularity of the overhead wheel speed is also small. That is, the determination of the overhead wheel speed data is only related to the frame rate of the image frame data collected by the visual camera, and there is no need to obtain the overhead wheel speed data after the overhead wheel rotates for at least one circle, which has higher real-time performance.
[0087] Furthermore, the head sheave of the target drilling rig can be detected by a pressure sensor. In this embodiment, the specific implementation is as follows:
[0088] According to the pressure sensor, the air pressure data of the sheave area of the target drilling rig is collected in real time, and the air pressure data of the sheave area is used as the sheave status data; based on the air pressure data of the sheave area, the sheave speed data is determined through a preset air pressure-speed comparison table.
[0089] The rotation of the sky wheel will drive the air flow near the sky wheel, and the flowing air will change the atmospheric pressure here. The pressure sensor determines the atmospheric pressure near the sky wheel.
[0090] Based on this, the type of pressure sensor is determined by the actual use scenario and is not limited in this embodiment. The pressure sensor collects real-time air pressure data in the skywheel area, i.e., near the skywheel. The skywheel speed data is determined by lookup based on a pre-calculated pressure-speed comparison table containing the relationship between air pressure data and flywheel speed. A windshield can be installed between the skywheel and the pressure sensor to prevent ambient airflow from affecting the detection results. The specific device structure is determined by the actual use scenario and is not limited in this embodiment. Furthermore, a filtering unit can be added to the pressure sensor to filter out interference from ambient noise.
[0091] Furthermore, the head sheave of the target drilling rig can be detected by a vibration sensor. In this embodiment, the specific implementation is as follows:
[0092] According to the vibration sensor, the vibration signal of the target drilling rig is collected in real time, and the vibration signal is used as the head sheave state data; based on the vibration signal, the head sheave speed data is determined through a preset vibration speed comparison table.
[0093] Among them, the vibration sensor is set on the head wheel of the target drilling rig, or on a fixed shaft directly connected to the head wheel. The head wheel will generate vibration during rotation, and the vibration spectrum is correlated with the rotation of the head wheel.
[0094] Based on this, the type of vibration sensor is determined by the actual usage scenario and is not limited in this embodiment. Vibration information of the flywheel or the fixed shaft connected to the flywheel is collected, and the flywheel speed data is determined by lookup based on a pre-calculated vibration speed comparison table containing the relationship between the vibration signal and the flywheel speed. A filtering unit can also be added to the pressure sensor to filter out interference from ambient noise.
[0095] Furthermore, the head sheave of the target drilling rig can be detected by using an acoustic pressure sensor. In this embodiment, the specific implementation is as follows:
[0096] According to the sound pressure sensor, the head sheave sound signal of the target drilling rig is collected in real time, and the head sheave sound signal is used as the head sheave status signal; based on the head sheave sound signal, the head sheave speed data is determined through a preset sound speed comparison table.
[0097] The sound pressure sensor is arranged near the head sheave of the target drilling rig and is used to detect the sound signals generated between the head sheave and the lifting chain and between the head sheave and the air during the rotation of the head sheave.
[0098] Based on this, the type of sound pressure sensor is determined by the actual usage scenario and is not limited in this embodiment. By collecting the sound signals generated between the crown sheave and the lifting chain, and between the crown sheave and the air, and based on a pre-calculated sound speed comparison table containing the relationship between the sound signal and the flywheel speed, the crown sheave speed data is determined by looking up the table. A sound insulation device can also be installed between the crown sheave and the sound pressure sensor to prevent the sound of the external environment from affecting the detection results. The specific device structure is determined by the actual usage scenario and is not limited in this embodiment. In addition, a filtering unit can be added to the sound pressure sensor to filter out interference from environmental noise.
[0099] Furthermore, the Doppler effect can be used to detect the head sheave of the target drilling rig. In this embodiment, the specific implementation is as follows:
[0100] A sound generating assembly is installed on the head sheave of the target drilling rig; a sound signal of the sound generating assembly is collected in real time using a sound pressure sensor, and the sound signal is used as the head sheave status data; and the head sheave speed data is determined based on the sound signal through the Doppler effect.
[0101] Among them, the sound-emitting component can be a component that emits sound through a specific structure of the component according to the airflow generated by the movement of the sky wheel, such as a whistle, or it can be a component for sending a specific sound, such as a speaker. The specific type and structure of the sound-emitting component are determined by the actual usage scenario and are not limited in this embodiment.
[0102] Based on this, the sound-generating component is installed on the sky wheel. The movement of the sky wheel will drive the sound-generating component to move together, while the position of the sound pressure sensor remains unchanged, so that the distance between the sound pressure sensor and the sound-generating component will change. According to the Doppler effect, the wavelength of the radiation emitted by the object changes due to the relative motion of the wave source and the observer. Then the tone of the sound signal emitted by the generating component collected by the sound pressure sensor changes periodically. The time it takes for the sky wheel to rotate once is determined based on the change period, and then the speed of the sky wheel is calculated.
[0103] In addition, a sound insulation device can be set between the overhead wheel and the sound pressure sensor to prevent the sound of the external environment from affecting the detection results. The specific device structure is determined by the actual usage scenario and is not limited in this embodiment. A filtering unit can also be added to the sound pressure sensor to filter out the interference of environmental noise.
[0104] Furthermore, the head sheave of the target drilling rig can be detected by setting more than one sensor. In this embodiment, the specific implementation is as follows:
[0105] According to at least one sensor sub-device among the preset sensors, the target drilling rig is monitored in real time to obtain the sheave status sub-data corresponding one-to-one to the at least one sensor sub-device; based on the at least one sheave status sub-data, the sheave speed sub-data corresponding one-to-one to the at least one sheave status sub-data is determined according to a preset speed algorithm.
[0106] Furthermore, if more than one sensor collects the speed data of the crown wheel, then when judging the state of the lifting chain, the collection results of each sensor must also be combined. In this embodiment, the specific implementation is as follows:
[0107] According to preset status judgment conditions, the status of the at least one sheave speed sub-data is judged in turn to obtain status data corresponding to the at least one sheave speed sub-data, wherein the status data includes a broken chain state and a non-broken chain state, and the broken chain state and the non-broken chain state correspond to different scoring values; according to a preset weighting coefficient, the scoring value corresponding to the at least one status data is weightedly calculated to obtain a broken chain scoring value; when the broken chain scoring value exceeds a preset broken chain scoring threshold, the shutdown instruction and the early warning instruction are generated.
[0108] Among them, due to the different anti-interference capabilities of various sensors, for example, sound pressure sensors and pressure sensors, in open-air working environments such as mines, face more interference sources and have lower anti-interference capabilities. Visual sensors, on the other hand, are less susceptible to interference from the mine environment. Therefore, the confidence levels of the data collected by various sensors are different. Different weights need to be set for different sensors to facilitate comprehensive consideration of the data collection results of different sensors.
[0109] Based on this, different sensors are used to collect relevant data on the target drilling rig to determine the status of the sheave. The speed of the sheave is then calculated based on the collected data. The speed data obtained is then compared with the threshold speed. When the speed is greater than the threshold speed, the lifting chain is considered broken, and the status data is determined to be a broken chain state. Otherwise, it is a non-broken chain state. The status data determined by each sensor is weighted by the weight coefficient corresponding to each sensor. It should be noted that the weight coefficient can be determined through prior measurement. Sensors with stronger anti-interference capabilities have higher weight coefficients, while sensors with stronger anti-interference capabilities have lower weight coefficients. The status data obtained by each sensor is then combined with the weight coefficients of each sensor to obtain a score value. If this score value is higher than the preset score threshold, the current lifting chain is determined to be broken, and a shutdown command and warning command are generated.
[0110] In summary, by integrating the data collection results of multiple sensors, we can avoid the misjudgment of a single sensor due to environmental interference, effectively improve the detection accuracy, and enhance the usability in different scenarios.
