Abstract
Description
Technical Field
[0001] This invention relates to the field of coal mining support technology, and in particular to a lightweight hydraulic support for thin coal seams, an intelligent remote control system, and a voice remote control method. Background Technology
[0002] With the continuous increase in domestic coal mining, thin coal seam mining has received considerable attention. Thin coal seams account for approximately 18% of my country's total coal reserves, but their mining volume accounts for only 7.3% of the national total. Due to the extremely complex underground environment of coal mines, which often contains explosive hazards such as gas and coal dust, especially during thin coal seam mining, the pedestrian passages within the hydraulic supports are extremely narrow, severely restricting personnel movement and forcing them to crawl. This presents numerous safety hazards and occupational disease risks. To reduce the labor intensity of workers and protect their health, fully mechanized mining faces have seen significant development in recent years. However, due to the complexity of underground geological conditions, manual intervention and maintenance are still necessary in current fully mechanized mining faces.
[0003] Therefore, it is essential to develop intelligent remote-controlled lightweight hydraulic supports for thin coal seams that can be programmed by voice. Through the voice-controlled intelligent system, the hands of the support operators in the mine can be freed up. Moreover, the operating system is also very comprehensive in function, and the support has a novel structure, small geometric size, high support efficiency, and light overall weight.
[0004] The existing intelligent remote control system for lightweight hydraulic supports in thin coal seams has the following problems:
[0005] 1. Due to the miniaturization of remote controls, the number of buttons has been continuously reduced, while the required control functions are constantly increasing. This has forced many functions to use combination buttons, or even require menu selection, causing great inconvenience to operators.
[0006] 2. Voice-controlled remote controls can only recognize Mandarin and a few dialects. Given my country's vast territory and the numerous coal mining areas across the country, with countless dialects and slang, the voice recognition rate is low, potentially leading to misoperation and posing significant safety hazards.
[0007] 3. Voice control can control the lifting and extending of the jack, but for slightly more complex actions, multiple voice commands need to be issued, and the support controller must respond to and confirm each command. This is not only time-consuming and labor-intensive, but also requires the operator to have good logical thinking and verbal communication skills, which many operators lack in reality. As for even more complex actions, traditional voice-controlled remote controls are no longer sufficient. Summary of the Invention

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0066] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0067] Combination Figures 1 to 7 According to an embodiment of the present invention, a lightweight hydraulic support for thin coal seams is provided, comprising: a top beam 1 and a base 5, and a guide rod 3 and a guide sleeve 4 disposed between the top beam 1 and the base 5. The guide rod 3 is connected to the top beam 1, the guide sleeve 4 is mounted on the base 5, and the top beam 1 is provided with a top beam side guard plate 2.
[0068] The hydraulic support also includes: an adjusting beam 7, an adjusting jack 11, a push rod 6, a moving jack 10, a pair of front uprights 8, and a pair of rear uprights 9. The adjusting beam 7 is arranged on one side of the base 5, and the adjusting jack 11 is installed on the base 5. The push rod 6 is connected to the moving jack 10. The base 5 is provided with a pair of front upright sockets 12 and a pair of rear upright sockets 21, and the pair of front uprights 8 and the pair of rear uprights 9 are respectively installed in the pair of front upright sockets 12 and the pair of rear upright sockets 21.
[0069] According to an embodiment of the present invention, the guide rod 3 and the guide sleeve 4 are connected in an inverted configuration. Figure 4 and Figure 5The guide sleeve 4 includes an upper edge 16, and a first limiting block 18 is welded to the bottom 17 of the guide rod 3. The guide rod 3 is embedded in the guide sleeve 4, and the guide rod 3 is limited by the first limiting block 18 and the upper edge 16 of the guide sleeve, and connected in an inverted structure.
[0070] In this invention, the guide rod 3 and the guide sleeve 4 are connected by an inverted structure, which increases the strength of the guide sleeve 4 frame plate and the contact area between the guide sleeve 4 and the guide rod 3. In one embodiment, a leaf spring 13 is installed on the guide rod 3.
[0071] Guide rod 3 and guide sleeve 4 adopt a two-stage vertical guide rod structure, and guide sleeve recess 15 is located at the center of the width direction of base 5 (e.g., Figure 2 As shown in the figure, the guide sleeve 4 is positioned at the center of the width direction of the base 5. The guide rod 3 and the guide sleeve 4 of the present invention adopt a two-stage vertical guide rod structure, and the guide sleeve 4 is entirely contained within the guide sleeve recess 15 of the base 5, which increases the extension ratio and overlap of the guide rod 3 and the guide sleeve 4.
[0072] According to an embodiment of the present invention, the base 5 is provided with a guide sleeve recess 15, and the guide sleeve 4 is installed in the guide sleeve recess 15. The guide sleeve 4 and the guide sleeve recess 15 are fixed by a second limiting block 14. Specifically, grooves are formed on the sides of the guide sleeve recess 15 and the guide sleeve 4, and the second limiting block 14 is embedded in the grooves. The guide sleeve 4 and the guide sleeve recess 15 are fixed by a pin 19 inserted from top to bottom.
[0073] like Figure 6 As shown, the second limiting block 14 of the present invention has a cuboid structure, which increases the cross-sectional area and makes the second limiting block 14 more reliable. At the same time, the use of pin shaft 19 to insert from top to bottom reduces the horizontal installation space, which can increase the size of the guide sleeve 4 and avoid interference between the base 5 and a pair of front columns 8 and / or a pair of rear columns 9 when the hydraulic support top beam 1 is under eccentric load.
[0074] The present invention provides a pair of front columns 8 and a pair of rear columns 9 to form a four-column support, thereby reducing the bending moment at the top beam 1 and the pair of front column recesses 12 and the pair of rear column recesses 21.
[0075] According to an embodiment of the present invention, the lower surface of the top beam 1, the upper surface of the base 5, and the upper surface of the push rod 6 form a variable cross-section structure. A variable cross-section structure means that the lower surface of the top beam 1, the upper surface of the base 5, and the upper surface of the push rod 6 have uneven slopes. Figure 3 As shown, taking the lower surface of the top beam 1 as an example, the lower surface of the top beam 1 includes a first surface a1 connected to the front column 8, a second surface a2 near the front end of the hydraulic support, and a third surface a3 near the rear end of the hydraulic support. A first slope a4 is formed between the first surface a1 and the second surface a2, and a second slope a5 is formed between the first surface a1 and the third surface a3. Thus, the lower surface of the top beam 1 forms an uneven slope, parallel to... Figure 3Looking at the longitudinal section in the direction of the paper, the lower surface of the top beam 1 is the variable cross section.
[0076] Similarly, the upper surface of the base 5 and the upper surface of the push rod 6 are also variable cross-sections. In some embodiments, the upper surface of the base 5 and the upper surface of the push rod 6 need not be exactly the same as the variable cross-section of the lower surface of the top beam 1, as long as the upper surface of the base 5 and the upper surface of the push rod 6 can have uneven slopes.
[0077] The lower surface of the top beam 1, the upper surface of the base 5, and the upper surface of the push rod 6 of this invention form a variable cross-section structure. While ensuring a sufficient safety factor, high-strength steel plates and advanced welding processes are used to reduce the workpiece cross-sectional thickness, allowing full utilization of the space within the hydraulic support. Even with a minimum working height of 0.75 meters, the operation and maintenance of the hydraulic support are convenient. Figure 3 The diagram shows the downward movement of the top beam of a lightweight hydraulic support for thin coal seams. After the top beam 1 is moved down, there is sufficient space inside the hydraulic support when mining thin coal seams.
[0078] In one embodiment, the outer main reinforcement at a pair of front column sockets 12 and a pair of rear column sockets 21 of the hydraulic support base is designed with a reduced height to ensure that all hydraulic components, including the front column 8 and the rear column 9, can be replaced when the hydraulic support is raised to a height of 0.75m.
[0079] In one embodiment, a pedestrian passage is provided between the front ends of a pair of front columns 12 of the hydraulic support and the scraper conveyor (the scraper conveyor is located at the front end of the push rod 6), and an inspection passage is provided between the pair of front columns 12 and the pair of rear columns 21.
[0080] Combination Figure 1 , Figure 2 and Figure 7 According to an embodiment of the present invention, the head of the adjusting jack 11 forms a stepped platform 20, and the adjusting beam 7 abuts against the stepped platform 20 and is fixedly connected to the head of the adjusting jack 11. Specifically, the stepped platform 20 is formed by milling a flat surface, so that the head of the adjusting jack 11 is concave in the axial direction of the adjusting jack 11, and the distance d between the upper and lower ends of the head of the adjusting jack 11 is less than the diameter D of the adjusting jack 11. The adjusting beam 7 abuts against the stepped platform 20, thereby lifting the adjusting beam 7 as a whole upward, so that a certain gap is formed between the adjusting beam 7 and the bottom plate of the base 5.
[0081] In thin coal seam working faces, during normal coal mining operations, there will inevitably be a certain height difference between the bases 5 of two adjacent hydraulic supports. If the hydraulic support base 5 adopts a variable cross-section, but the adjusting beam 7 is still designed conventionally, the adjusting beam 7 will be too close to the outer edge of the base plate of the base 5. This can easily cause interference between the adjusting beam 7 of the hydraulic support and the base 5 of the adjacent hydraulic support, damaging the adjusting jack 11. In this invention, the head of the adjusting jack 11 of the hydraulic support is milled to form a stepped platform 20 that cooperates with the adjusting beam 7. This increases the distance between the adjusting beam 7 and the outer edge of the base plate of the base 5, reducing interference between the adjusting beam 7 of the hydraulic support and the base 5 of the adjacent hydraulic support.
[0082] The lightweight hydraulic support for thin coal seams provided by this invention is remotely controlled via an intelligent remote control system, such as... Figure 8 The diagram shown is a structural block diagram of the remote controller for an intelligent remote control system of a lightweight hydraulic support for thin coal seams according to the present invention. Figure 9 The diagram shows an audio recording schematic of an intelligent remote control system for a lightweight hydraulic support in a thin coal seam according to the present invention. According to an embodiment of the present invention, an intelligent remote control system for a lightweight hydraulic support in a thin coal seam is provided, including a remote controller and a support controller. The support controller is arranged on the lightweight hydraulic support in the thin coal seam, for example, between a pair of front columns 8. The support controller and the remote controller transmit signals remotely.
[0083] According to an embodiment of the present invention, the remote controller includes an embedded central processing system 100, a power supply system 300, a data acquisition system 500, a human-computer interaction system 200, and a communication system 400.
[0084] The embedded central processing system 100 incorporates a voice control subroutine for voice remote control of lightweight hydraulic supports in thin coal seams.
[0085] The embedded central processing system 100 includes an audio data storage unit 101 and a function data storage unit 102. The audio data storage unit 101 is used to store multiple audio data entries recorded by the remote control, and the function data storage unit 102 is used to store multiple logical function modules.
[0086] The power supply system 300 is used to supply power to the embedded central processing system 100. The power supply system 300 includes a voltage comparison module 301, a battery module 302, and a charging module 303.
[0087] The data acquisition system 500 is used to collect data and send the collected data to the embedded central processing system 100. The data acquisition system 500 includes a personnel positioning module 501, an audio input module 502, and a hazardous gas detection module 503.
[0088] A communication system 400 is used to receive the data processed by the embedded central processing system 100, convert it into control instructions, and send the control instructions to the support controller. The communication system 400 includes a Lora module 401, a Zigbee module 402, and a WIFI module 403.
[0089] A human-computer interaction system 200 is used for human-computer interaction with staff. The human-computer interaction system 200 includes a Bluetooth module 201, an audio output module 202, a button module 203, an LCD display module 204, and an infrared transceiver module 205.
[0090] For an intelligent remote control system of a thin coal seam light hydraulic support in the present invention, the logic function modules are stored in the function data storage unit 102. By inputting audio, the input audio is mapped one by one with the logic functions of the logic function modules in the function data storage unit 102.
[0091] As Figure 9 shown, the audio is input into the embedded central processing system 100 through the audio input module 502, converted into multiple audio data, and stored in the audio data storage unit 101. The staff inputs audio data according to the dialect and idiomatic expressions used, such as "lower the support", "pull the scraper conveyor", "retract the bottom adjustment".
[0092] The embedded central processing system 100 converts "lower the support", "pull the scraper conveyor", "retract the bottom adjustment" into No. 1 audio data strip, No. 2 audio data strip, No. 3 audio data strip,..., No. n audio data strip, and stores the No. 1 audio data strip, No. 2 audio data strip, No. 3 audio data strip,... in the audio data storage unit 101, and maps them one by one with the logic functions of the logic function modules in the function data storage unit 102. In one embodiment, the No. 1 audio data strip maps to the AND function module in the function data storage unit 102, the No. 2 audio data strip maps to the OR function module in the function data storage unit 102, the No. 3 audio data strip maps to the NOT function module in the function data storage unit 102, the No. 4 audio data strip maps to the IF function module in the function data storage unit 102,...
[0093] Different logic function modules in the function data storage unit 102 correspond to different logic functions. For example, the AND function module corresponds to the AND function, the OR function module corresponds to the OR function, the NOT function module corresponds to the NOT function, the IF function module corresponds to the IF function,...
[0094] This invention involves staff recording audio for voice remote control (the voice remote control method is described below). Since it does not rely on speech recognition, there are no strict restrictions on the audio recording and the content of the voice and sentences used for voice remote control input. Staff can freely use dialects and / or colloquialisms for audio recording and voice input. The entire audio recording process is completed with the cooperation of staff and does not require highly skilled operating tools.
[0095] Figure 10 The diagram shows a flowchart of a voice remote control method for a lightweight hydraulic support in a thin coal seam according to the present invention. According to an embodiment of the present invention, a voice remote control method for a lightweight hydraulic support in a thin coal seam is provided, which uses an intelligent remote control system to remotely control the support via voice, including the following steps:
[0096] Step S1: Activate the voice control trigger signal.
[0097] When the embedded central processing system 100 receives the voice control trigger signal instruction from the human-computer interaction system 200, the embedded central processing system 100 starts the voice control subroutine and enters step S2 to collect audio data; otherwise, the embedded central processing system 100 does not start the voice control subroutine.
[0098] In one embodiment, the staff sends a voice control trigger signal command to the embedded central processing system 100 through the button module 203 of the human-computer interaction system 200, and makes voice input, such as "lower the frame", through the audio input module of the data acquisition system 500.
[0099] Step S2: Collect audio data.
[0100] The embedded central processing system 100 acquires audio data sent by the data acquisition system 500.
[0101] Step S3: End voice control trigger signal.
[0102] When the embedded central processing system 100 receives the end voice control trigger signal instruction from the human-computer interaction system 200, it stops collecting audio data; otherwise, the embedded central processing system 100 continues to collect audio data sent by the data acquisition system 500.
[0103] In one embodiment, after a staff member inputs voice input, the button module 203 of the human-computer interaction system 200 sends an end-voice control trigger signal command to the embedded central processing system 100.
[0104] Step S4: Noise reduction processing.
[0105] The embedded central processing system 100 performs noise reduction processing on the acquired audio data. The noise reduction processing method can be set by those skilled in the art according to the specific environment, and will not be described in detail in the embodiments.
[0106] Step S5: Compare the collected audio data with the audio data in the audio data storage unit.
[0107] The embedded central processing system 100 compares the acquired audio data with the audio data in the audio data storage unit 101, and selects the audio data corresponding to the acquired audio data from the audio data storage unit 101.
[0108] Step S6: Retrieve the corresponding instruction.
[0109] The embedded central processing system 100 retrieves and collects logical functions corresponding to the audio data within the functional data storage unit 102.
[0110] For example, after step S5, if the audio data corresponding to the collected audio data in the audio data storage unit 101 is audio data bar number 1, then the corresponding functional data storage unit 102 corresponds to the AND function module, and the corresponding logical function is the AND function.
[0111] Step S7: Determine whether the collected audio data is a basic instruction.
[0112] If the collected audio data is the basic instruction, proceed to step S9; otherwise, proceed to step S8.
[0113] Basic instructions refer to audio data that can be represented without logical operations. For example, when the embedded central processing system 100 inputs audio data, "lowering the support" is converted into audio data bar number 1. Audio data bar number 1 maps to the AND function module of the functional data storage unit 102. When the staff inputs "lower the support" by voice, the embedded central processing system 100 directly retrieves the corresponding AND function of the AND function module in the functional data storage unit 102. At this time, audio data bar number 1 corresponding to "lowering the support" is the basic instruction. At the same time, the basic instruction is also the control instruction, and step S9 is entered to send the control instruction to the support controller to control the thin coal seam lightweight hydraulic support.
[0114] Step S8: Perform instruction combination logic operations on the collected audio data, and proceed to step S9.
[0115] When the collected audio data is not a basic command, for example, when the staff inputs "lower the frame or pull it away, without retracting the bottom tone", the audio data storage unit 101 of the embedded central processing system 100 does not store the complete audio data bar when the audio is recorded. It only stores the audio data bar No. 1 corresponding to "lower the frame", the audio data bar No. 2 corresponding to "pull it away", and the audio data bar No. 3 corresponding to "retract the bottom tone".
[0116] At this point, the AND function of the AND function module corresponding to audio data bar 1, the OR function of the OR function module corresponding to audio data bar 2, and the NOT function of the NOT function module corresponding to audio data bar 3 are used to generate audio data bar n by performing instruction combination logic operations on audio data bars 1, 2, and 3 in the combination logic function module. This n-th audio data bar is used as the control instruction for "lowering the frame or pulling back without retracting the base tone".
[0117] Step S9: Send control commands to the support controller to control the thin coal seam lightweight hydraulic support.
