These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] It should be noted that, in the description of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

Therefore, they should not be construed as limitations on the present invention.

[0048] Deep-hole rock drills are widely used in drilling operations in complex geological conditions such as mining and tunneling. During actual construction, due to factors such as rock fissures, uneven hardness, or complex geological structures, the drill bit is prone to jamming during drilling. Jamming occurs when the drill bit becomes stuck in the borehole due to excessive rock resistance or deviation in the drilling direction, preventing the rock drill from advancing normally. Existing rock drill reverse-stroke control technology is mainly divided into passive control and active control. Passive control schemes achieve reverse-stroke through mechanical or hydraulic structures; active control schemes switch the reverse-stroke hydraulic circuit manually or via an electrically controlled directional valve. However, in existing technologies, active control schemes rely on manual judgment, and passive control schemes require the high-pressure hydraulic circuit to be constantly switched on and off. Existing technologies suffer from problems such as delayed reverse-stroke response and insufficient reliability.

[0049] To solve the above-mentioned technical problems, the present application proposes the following technical concept: Considering the real-time monitoring of the rotation pressure of the rock drill, the inventor compares the rotation pressure with a preset pressure threshold. If the rotation pressure is greater than the preset pressure threshold, it is determined that the rock drill is in a stuck state. The controller executes a control command to control the reverse oil circuit to be open. The reverse oil flows into the reverse oil chamber through the reverse oil circuit. The reverse oil applies oil pressure to the step of the drill bit, pushing the drill bit to reverse.

[0050] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] Figure 1 This is a schematic diagram illustrating an application scenario of the rock drill reverse-damping control method provided in the embodiments of this application. For example... Figure 1 As shown, the rock drill includes a controller, a rock drill body 1, a drill tail 2, a reverse oil port 11, a reverse oil chamber 12, and a drill tail step 21.

[0052] Specifically, the controller obtains the rotation pressure of the rock drill and compares it with a preset pressure threshold. If the rotation pressure is greater than the pressure threshold, the rock drill is determined to be stuck. The controller executes the control command to open the reverse oil port 11. The reverse oil flows into the reverse oil chamber 12 through the reverse oil port 11. The reverse oil applies oil pressure to the drill tail step 21 of the drill tail 2, pushing the drill tail to reverse.

[0053] Figure 2 Flowchart of the rock drill reverse-drilling control method provided in this application Figure 1 ,like Figure 2 As shown, the method includes:

[0054] S201: Obtain the rotational pressure of the rock drill, compare the rotational pressure with the preset pressure threshold, and generate a comparison result.

[0055] Specifically, the oil inlet pressure of the rotary motor is obtained through a pressure sensor. The pressure sensor transmits the pressure signal to the controller. The comparison module in the controller compares the real-time collected rotary pressure value with the preset pressure threshold stored in the non-volatile memory to generate a comparison result.

[0056] S202: If the rotational pressure is greater than the preset pressure threshold in the comparison results, the rock drill is determined to be in a stuck state, and a control command is generated.

[0057] Specifically, the controller scans and compares the results. If the detected result is true and the state continues to exceed the preset anti-shake time, the program logic determines that the rock drill is in a stuck state, and the main control program calls the reverse control subroutine to generate control commands.

[0058] S203: The controller executes control commands to control the reverse oil circuit to open.

[0059] Specifically, the digital output module outputs a voltage signal to the rock drill according to the received control command, which controls the rock drill to open the reverse oil port, so that the reverse oil circuit is connected.

[0060] S204: Reverse oil flows into the reverse oil chamber through the reverse oil passage. The reverse oil applies hydraulic pressure to the step of the drill bit, pushing the drill bit to achieve the reverse function.

[0061] Specifically, driven by the oil pump, the reverse oil enters the reverse oil chamber through the already opened reverse oil circuit. The oil pressure acts on the step, generating a rod-pulling force, which drives the rod tip to move, thus realizing the reverse function.

[0062] In this embodiment, the rock drill can be equipped with an independent manual or electric on / off controller, which allows for manual selection of when to activate the reverse drilling mechanism.

[0063] As can be seen from the above embodiments, by monitoring the rotation pressure and comparing the rotation pressure with the preset pressure threshold in real time, if the rotation pressure is greater than the preset pressure threshold, it is determined that the rock drill is in a stuck state. The controller executes the control command to control the reverse oil circuit to be opened. The reverse oil flows into the reverse oil chamber through the reverse oil circuit. The reverse oil applies oil pressure to the step of the drill bit, pushing the drill bit to realize the reverse function, thus avoiding the problems of delayed reverse response and insufficient reliability.

[0064] In one embodiment of this application, the method further includes the following steps before step S203:

[0065] S301: When the rock drill is in the stuck state, the step at the drill bit drives the reverse piston to move, and the reverse piston oil passage in the reverse piston is connected to the reverse oil port.

[0066] S302: The reverse oil flows into the reverse oil chamber through the reverse piston oil passage. The reverse oil applies hydraulic pressure to the reverse piston, and the reverse piston applies a pulling force to the rod tip through the step at the rod tip.

[0067] Figure 3 This is a structural schematic diagram of the rock drill provided in this application.

[0068] like Figure 3 As shown, a reverse piston 3 can also be installed in the rock drill, and a reverse piston oil passage 31 is provided inside the reverse piston 3.

[0069] In this embodiment, the rock drill can be equipped with an independent manual or electric on / off controller, which allows for manual selection of when to activate the reverse drilling mechanism.

[0070] Specifically, the reverse oil, driven by the oil pump, flows to the reverse oil passage set in the reverse piston, and flows into the reverse oil chamber through the reverse oil passage. The high-pressure oil acts on the end face of the reverse piston, generating thrust. The piston moves under the action of oil pressure, pressing against the step of the drill bit, generating a pulling force at the drill bit, pushing the drill bit, and realizing reverse drilling.

[0071] As can be seen from the above embodiments, by setting a reverse piston inside the rock drill, when the rock drill gets stuck, the step at the drill bit drives the reverse piston to move. The reverse piston oil passage in the reverse piston is connected to the reverse oil port. The reverse oil flows through the reverse piston to the reverse oil chamber. The reverse oil applies oil pressure to the reverse piston. The reverse piston applies a pulling force to the drill bit through the step at the drill bit, pushing the drill bit to reverse, thus avoiding the problems of delayed reverse response and insufficient reliability.

[0072] Figure 4 Flowchart of the rock drill reverse-drilling control method provided in this application Figure 2 ,like Figure 4 As shown, the procedure before step S203 also includes:

[0073] S401: Obtain the operating status information of the oil circuit.

[0074] Specifically, the system's hydraulic status monitoring unit continuously acquires the operating status information of the oil circuit through flow sensors, pressure sensors, and valve core displacement sensors installed on the reverse oil circuit.

[0075] In this embodiment, the operating status information includes, but is not limited to, real-time flow rate, whether pressure has been established, and solenoid valve feedback signals.

[0076] S402: If a fault occurs in the oil circuit, an oil circuit switching command will be generated.

[0077] Specifically, the diagnostic analysis program detects status information and generates an oil circuit switching command when an oil circuit fault is detected.

[0078] S403: Switch to the backup oil circuit according to the oil circuit switching command.

[0079] Specifically, the output module outputs an oil circuit switching command to cut off the power supply to the main oil circuit solenoid valve, supply power to the backup oil circuit solenoid valve, and guide the pressurized oil to the backup oil circuit.

[0080] As can be seen from the above embodiments, by acquiring the operating status information of the oil circuit, if a fault occurs in the oil circuit, an oil circuit switching command is generated. The controller automatically executes the switching command to switch to the backup oil circuit, thereby improving the long-term reliability of the system through redundant control loops and fault self-diagnosis mechanisms.

[0081] Figure 5 Flowchart of the rock drill reverse-drilling control method provided in this application Figure 3 ,like Figure 5 As shown, after step S203, the following steps are also included:

[0082] S501: Obtain the hydraulic pressure of the rock drill impact oil circuit and the hydraulic pressure of the rock drill buffer oil circuit.

[0083] Specifically, the analog input module synchronously reads the signals from two pressure sensors connected to the rock drill's impact oil circuit and buffer oil circuit, thereby obtaining the hydraulic pressure values ​​of these two oil circuits in real time.

[0084] S502: Compare the hydraulic pressure of the rock drill impact oil circuit with the hydraulic pressure of the rock drill buffer oil circuit to generate a pressure comparison result.

[0085] Specifically, the arithmetic logic unit performs real-time comparison calculations on the two pressure values. It continuously determines whether the impact oil circuit pressure is greater than the buffer oil circuit pressure and generates a binary pressure comparison result: if the impact pressure is higher, the result is "impact oil circuit priority"; otherwise, it is "buffer oil circuit priority".

[0086] S503: If the hydraulic pressure of the rock drill impact oil circuit is greater than the hydraulic pressure of the rock drill buffer oil circuit, then the impact oil in the rock drill impact oil circuit shall be selected as the oil source.

[0087] Specifically, if the pressure comparison result is "impact oil circuit priority", the oil source management logic selects the rock drill impact oil circuit as the oil supply source for this counter-strike action, and the control program operates the corresponding oil circuit selection valve group to temporarily divert part of the high-pressure oil flow from the impact oil circuit to the counter-strike oil circuit, so as to use this high-pressure impact oil as the oil source for the counter-strike action.

[0088] As can be seen from the above embodiments, after the reverse oil circuit is connected, the system monitors the hydraulic pressure of the impact oil circuit and the buffer oil circuit in real time, compares the oil pressure, selects the oil circuit with higher oil pressure as the reverse oil source, optimizes the oil supply path, and ensures the efficient output of the pull rod force.

[0089] Figure 6 Flowchart of the rock drill reverse-drilling control method provided in this application Figure 4 ,like Figure 6 As shown, after step S203, the following steps are also included:

[0090] S601: Obtain multi-dimensional geological information for rock drilling operations.

[0091] In this embodiment, multi-dimensional geological information includes, but is not limited to, rock hardness grade, degree of fracture development, and formation characteristics derived from drilling speed and vibration spectrum.

[0092] S602: Generate threshold adjustment strategy based on multi-dimensional geological information.

[0093] For example, based on the analysis of multi-dimensional geological information by the strategy engine, when it identifies "high rock hardness and few cracks", the engine determines that rigid jamming is more likely to occur and a more sensitive response is required. Therefore, a threshold adjustment strategy is generated, which is: "Adjust the preset pressure threshold from 18MPa to 15MPa".

[0094] S603: Adjust the pressure threshold according to the threshold adjustment strategy.

[0095] Specifically, the main control program adjusts the stored preset pressure threshold variables and judges whether the adjusted threshold meets the actual geological requirements.

[0096] As can be seen from the above embodiments, by acquiring multi-dimensional geological information of rock drilling operations and generating a threshold adjustment strategy based on the multi-dimensional geological information, the pressure threshold is dynamically adjusted, thus avoiding the risk of drill jamming.

[0097] In one embodiment of this application, step S204 is followed by:

[0098] S205: When the slewing pressure is lower than the preset pressure threshold, an oil circuit shut-off command is generated.

[0099] Specifically, during or after the counter-attack, the rotation pressure is continuously monitored. When the rotation pressure is detected to be lower than the preset pressure threshold and stabilized for a period of time, the main control program determines that the counter-attack is complete and generates an oil circuit shutdown command.

[0100] S206: The controller executes the oil circuit shutdown command to control the reverse oil circuit to shut down.

[0101] Specifically, the output module executes the oil circuit shutdown command, stops supplying power to the reverse oil circuit solenoid valve, and the rock drill closes the reverse oil port.

[0102] As can be seen from the above embodiments, by monitoring the rotation pressure value in real time, when the rotation pressure is lower than the pressure threshold, an oil circuit shutdown command is generated, and the reverse oil circuit is shut off by the controller, so as to avoid the risk of equipment oil leakage caused by prolonged connection to the reverse oil port.
