Description

Technical Field

[0001] This invention relates to the field of mining tunneling technology, and more specifically to an automatic electrode placement device for mining tunneling. Background Technology

[0002] During the excavation of mine roadways or tunnels, hidden disaster-causing factors ahead of the working face (such as high-stress zones, geological structures, fault fracture zones, water-rich areas, and gas-rich areas) are important contributing factors to accidents such as water inrush, roof collapse, rock bursts, and coal and gas outbursts. Real-time, continuous, and advanced detection of geological anomalies ahead of the excavation is crucial to ensuring safe tunneling.

[0003] Underground engineering advanced geological exploration mainly falls into two categories: drilling methods and geophysical methods. Drilling methods involve drilling ahead of the working face to collect samples and assess the geological structure ahead. Essentially, it's a point-based approach and cannot comprehensively reflect the geological conditions ahead of the entire working face. Among geophysical methods, the parallel electrode method (PED) shows promising application prospects. This method actively applies an electric field to the exploration area and analyzes the electrical response of the rock strata to identify unfavorable geological bodies such as high-water areas and collapse columns. However, this existing technology has the following limitations: First, the electrodes must be fixed in the surrounding rock of the tunnel through manual drilling. As the tunnel face advances, frequent manual retrieval and repositioning of the electrodes are required, which is cumbersome and severely interferes with continuous tunneling operations. There is an urgent need for an automatic electrode placement device for mine tunneling to solve these problems. Summary of the Invention

[0013] Furthermore, the rotating seat includes a first base plate disposed on the side wall of the conveyor frame, a second base plate disposed on the side wall of the first base plate, a positioning seat embedded in the side wall of the first base plate near the second base plate, and an annular stop groove formed inside the positioning seat; a pressing post connected to a second guide seat is embedded in the side wall of the second base plate away from the first base plate, a fixing block is disposed inside the second base plate, a connecting post penetrating the fixing block is disposed at the end of the pressing post, a spring is sleeved on the side wall of the connecting post between the fixing block and the pressing post, a guide post is disposed at the end of the connecting post below the fixing block and inserted into the positioning seat, a pair of stop posts are symmetrically disposed on the side wall of the guide post, a guide hole matching the guide post is formed through the side wall of the positioning seat, a positioning groove matching the stop post is formed on the side wall of the positioning seat near the second base plate, and the positioning groove, the guide hole and the annular stop groove are interconnected.

[0030] The technical solutions in 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, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0031] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0032] like Figure 1 As shown, this embodiment of the invention provides an automatic electrode placement device for mining tunneling, comprising: a plurality of first guide seats 3 disposed on the side wall of the track side guard plate 1002 of the tunneling machine traveling part 1, and a plurality of second guide seats 10 disposed on the side wall of the frame of the belt conveyor 5; a first electrode assembly 4 is vertically disposed inside each of the plurality of first guide seats 3, a first drive mechanism 2 is disposed between the drive wheel 1001 and the guide wheel 1003 of the tunneling machine traveling part 1, the first drive mechanism 2 takes the rotation of the drive wheel 1001 and the guide wheel 1003 as the power input, and drives the plurality of first electrode assemblies 4 to move vertically and synchronously reciprocating; a second electrode assembly 6 is vertically disposed inside each of the plurality of second guide seats 10, and a second drive mechanism 7 is disposed on the side wall of the frame of the belt conveyor 5 for driving the plurality of second electrode assemblies 6 to move vertically and synchronously reciprocating. This design utilizes the rotation of the drive wheel 1001 and guide wheel 1003 as power input via the first drive mechanism 2 on the tunneling machine's traveling section 1. This drives multiple first electrode assemblies 4 to move vertically and synchronously back and forth along the first guide seat 3. The first electrode assemblies 4 can be quickly inserted into or removed from the ground, ensuring sufficient static time after insertion to improve measurement accuracy, while avoiding shear damage to the electrodes caused by the horizontal movement of the tunneling machine. This design enables the automatic relocation of the first electrode assemblies 4 during the tunneling process, eliminating the need for frequent manual retrieval and relocation. Electrode deployment is convenient and simple, ensuring intermittent electrode extension. The deployment enables continuous detection in all times and spaces. To ensure the required number of electrodes is met and the resistance cloud map is generated, the detection is completed. Multiple second electrode assemblies 6 are driven to move vertically and synchronously along the second guide seat 10 via the second drive mechanism 7 on the frame of the belt conveyor 5, inserting or removing the second electrode assemblies 6 from the ground. The first electrode assembly 4 and the second electrode assembly 6 are evenly distributed, have the same specifications, and are connected by a cable. The tunneling machine is connected to the belt conveyor 5 via a transfer machine. When the belt conveyor 5 is stationary, the second electrode assembly 6 remains inserted into the ground. When the position of the belt conveyor 5 is adjusted, the second electrode assembly 6 is removed from the ground.

[0033] Reference Figure 2 , Figure 3 , Figure 4 and Figure 9The first electrode assembly 4 includes a first electrode sleeve 41 vertically penetrating inside the first guide seat 3, with a first electrode 42 disposed at the bottom of the first electrode sleeve 41; the first drive mechanism 2 includes an eccentric wheel shaft 21 disposed at the end of the drive wheel 1001 of the tunneling machine traveling part 1 and a guide wheel shaft 27 disposed at the end of the guide wheel 1003 of the tunneling machine traveling part 1. Both the eccentric wheel shaft 21 and the guide wheel shaft 27 are provided with couplings 22 on their side walls. Each pair of couplings 22 is provided with a first crank 23. Each pair of first cranks 23 is provided with a slide rod 24. Each pair of slide rods 24 is slidably provided with an arc-shaped guide rail 25. A first connecting rod 26 is horizontally disposed between the pair of arc-shaped guide rails 25. The pair of arc-shaped guide rails 25 are symmetrically distributed at both ends of the first connecting rod 26. The first electrode sleeves 41 in the multiple first electrode assemblies 4 are all sleeved on the side walls of the first connecting rod 26; the first electrode sleeves 41 are slidably connected to the first guide seat 3. The design incorporates arc-shaped guide rails 25 at both ends of the first connecting rod 26. The sliding rod 24 at the end of the first crank 23 is embedded within and can slide within the arc-shaped guide rails 25. The curvature of the arc-shaped guide rails 25 matches the motion trajectory of the first crank 23. When the drive wheel 1001 and guide wheel 1003 of the tunneling machine's traveling section 1 rotate, they drive the eccentric wheel shaft 21 and guide wheel shaft 27 to rotate. The eccentric wheel shaft 21 and guide wheel shaft 27 follow the rotation of the drive wheel 1001 and guide wheel 1003, respectively, driving the coupling 22 on them to drive the corresponding sliding rod 24 to perform circular motion around the axes of the drive wheel 1001 and guide wheel 1003, and slide along the arc-shaped guide rails 25. This drives the arc-shaped guide rails 25 to move the first connecting rod 26 along the first electrode sleeve 4 of the multiple first electrode assemblies 4. 1. The horizontal reciprocating motion simultaneously drives the first electrode sleeve 41 in multiple first electrode assemblies 4 to drive the first electrode 42 on it to move vertically and synchronously along the first guide seat 3, so that the first electrode 42 in the first electrode assembly 4 can be quickly inserted into or pulled out of the ground. This ensures that the electrode has enough time to remain still after being inserted into the ground to improve measurement accuracy, and avoids shearing damage to the electrode caused by the horizontal movement of the tunneling machine. Among them, the coupling 22 is a separable coupling 22. When in non-working mode, the separable coupling 22 separates the first crank 23 from the guide wheel shaft 27 and the eccentric wheel shaft 21, and removes the first electrode assembly 4 as a whole from the tunneling machine. This avoids the first electrode 42 from being damaged when it is not needed to be installed on the concrete ground, and improves the service life of the first electrode 42.

[0034] Reference Figure 3 and Figure 4The arc-shaped guide rail 25 includes an arc-shaped seat 251 with one end of the first connecting rod 26. A pair of arc grooves 252 are symmetrically formed on the inner walls of opposite sides of the arc-shaped seat 251. A first horizontal groove 254 connected to the pair of arc grooves 252 is formed on the inner wall of the arc groove 252 near the first connecting rod 26. A second horizontal groove 256 connected to the pair of arc grooves 252 is formed on the inner wall of the arc groove 252 away from the first connecting rod 26. An arc-shaped limiting block 253 is provided at the center of the arc-shaped seat 251. A limiting groove 255 is formed between the side wall of the arc-shaped limiting block 253 and the inner walls of the pair of arc grooves 252, the first horizontal groove 254, and the second horizontal groove 256. The limiting groove 255 matches the sliding rod 24. The groove depth of the first horizontal groove 254 is greater than the groove depth of the second horizontal groove 256. The design uses the eccentric wheel shaft 21 and the guide wheel shaft 27 to rotate with the drive wheel 1001 and the guide wheel 1003 respectively, thereby driving the first crank 23 on it to perform circular motion. The first crank 23 drives the slide rod 24 on it to slide along the limiting slide groove 255. When the slide rod 24 slides in the arc groove 252, the first connecting rod 26 remains horizontal. When the slide rod 24 moves to the first horizontal groove 254 or the second horizontal groove 256 at the connection of the upper and lower arc grooves 252, the first connecting rod 26 generates a rapid vertical motion and moves laterally back and forth along the first electrode sleeve 41 in the multiple first electrode assemblies 4. The slide rod 24 and the arc The cooperation of the guide rail 25 is transformed into the vertical reciprocating motion of the first connecting rod 26, which in turn drives the first electrode assembly 4 to periodically insert and pull out of the ground, realizing the automatic deployment of the electrode as it is excavated. The first electrode assembly 4 is automatically deployed without the need for frequent manual retrieval and re-deployment of the electrode. The electrode deployment is convenient and the operation is simple. It ensures that the electrode has enough time to remain still after being inserted into the ground to improve the measurement accuracy, and avoids shearing damage to the electrode caused by the horizontal movement of the tunneling machine. When one of the slide rods 24 is located inside the first horizontal groove 254, the other slide rod 24 is located inside the second horizontal groove 256.

[0035] Reference Figure 5The second electrode assembly 6 includes a second electrode sleeve 61 vertically penetrating inside the second guide seat 10, a second electrode 62 at the bottom of the second electrode sleeve 61, and a connecting plate 63 located above the second guide seat 10 at the top of the second electrode 62; a pair of mounting seats 11 are symmetrically arranged on one side wall of the frame of the belt conveyor 5; the second drive mechanism 7 includes a pair of connecting plates 71 arranged on the side wall of the pair of mounting seats 11 close to each other, a drive motor 72 is arranged on the side wall of each pair of connecting plates 71, a second crank 73 is arranged on the output shaft of each pair of drive motors 72, and a second connecting rod 74 is rotatably arranged at the connection point of the pair of second cranks 73 away from the drive motors 72 through a connecting shaft 75, and the connecting plates 63 in the multiple second electrode assemblies 6 are all sleeved on the side wall of the second connecting rod 74; the second electrode sleeve 61 in the second electrode assembly 6 is slidably connected to the second guide seat 10. The design utilizes a pair of drive motors 72 in the second drive mechanism 7 to rotate the second cranks 73. The rotation of the second cranks 73, under the action of the connecting shaft 75, drives the second connecting rod 74 to move laterally back and forth along the connecting plate 63 in the multiple second electrode assemblies 6. Simultaneously, it drives the second electrode sleeves 61 in the multiple second electrode assemblies 6 to move the second electrodes 62 vertically back and forth synchronously along the second guide seat 10, allowing multiple second electrode assemblies 6 to be simultaneously inserted into or removed from the ground, improving the ease of installation and simplifying operation. When the second electrode assembly 6 moves vertically, the connecting plate 71 is positioned above the second connecting rod 74. Both the first electrode sleeve 41 and the second electrode sleeve 61 are made of insulating material.

[0036] Reference Figure 5 and Figure 6 The mounting base 11 has a drive lifting mechanism 8 on its side wall for driving the connecting plate 71 to move vertically. A rotating base 12 is provided between the second guide seat 10 and one side wall of the belt conveyor 5 frame. The rotating base 12 is used to drive the second electrode assembly 6 on the second guide seat 10 to rotate and tilt. In the non-working mode, the connecting plate 71 is driven to move downward by the drive lifting mechanism 8. The connecting plate 71 drives the drive motor 72 to move downward. When the axis of the drive motor 72 is below the second connecting rod 74, rotating the rotating base 12 drives the second electrode assembly 6 on the second guide seat 10 to rotate to a horizontal position and tilt and retract the second electrode assembly 6. This prevents the second electrode 62 from being easily damaged when it is not in use, thus protecting the second electrode assembly 6 and improving its service life.

[0037] Reference Figure 6The driving lifting mechanism 8 includes a sliding groove 85 formed in the side wall of the mounting base 11. A connecting plate 71 is disposed inside the sliding groove 85. A driving gear 83 is rotatably mounted inside the mounting base 11 via a first rotating shaft 82. A rack 84 meshing with the driving gear 83 is disposed on the side of the connecting plate 71 near the driving gear 83. One side of the driving gear 83 is a smooth surface and is provided with a rocker arm 81 that penetrates the side wall of the mounting base 11. This design drives the driving gear 83 to rotate via the rocker arm 81 in the driving lifting mechanism 8. The driving gear 83 drives the rack 84 to move vertically. The movement of the rack 84 causes the connecting plate 71 to move vertically along the sliding groove 85, which facilitates the adjustment of the height of the driving motor 72, thereby adjusting the height between the second crank 73 and the second connecting rod 74, and facilitating the operation of the second driving mechanism 7 to drive the second electrode assembly 6 to move vertically.

[0038] Reference Figure 6 The mounting base 11 is internally equipped with a stop mechanism 9 for stopping the rack 84. The stop mechanism 9 includes a second rotating shaft 93 located inside the mounting base 11. A pawl 91, which meshes with the rack 84, is rotatably mounted on the second rotating shaft 93. A foot pedal 92, penetrating the side wall of the mounting base 11, is located on the side of the pawl 91 away from the rack 84. This design uses the foot pedal in the stop mechanism 9 to drive the pawl 91 to rotate around the second rotating shaft 93, causing the pawl 91 to disengage from or engage with the teeth on the rack 84, thus stopping or releasing the rack 84 and fixing it after adjusting the height of the connecting plate 71.

[0039] Reference Figure 5 and Figure 6 The mounting base 11 has a first limiting groove 13 and a second limiting groove 14 sequentially formed on its side wall from top to bottom. The rocker arm 81 is disposed inside the first limiting groove 13, and the foot pedal 92 is disposed inside the second limiting groove 14. This design limits the rotation range of the rocker arm 81 and the foot pedal 92 by the first limiting groove 13 and the second limiting groove 14, respectively.

[0040] Reference Figure 5 , Figure 7 and Figure 8The rotating seat 12 includes a first base plate 121 disposed on the side wall of the frame of the belt conveyor 5, a second base plate 122 disposed on the side wall of the first base plate 121, a positioning seat 1212 embedded in the side wall of the first base plate 121 near the second base plate 122, and an annular stop groove 128 formed inside the positioning seat 1212; a pressing post 123 connected to the second guide seat 10 is embedded in the side wall of the second base plate 122 away from the first base plate 121, a fixing block 125 is disposed inside the second base plate 122, and a connecting post 1210 penetrating the fixing block 125 is disposed at the end of the pressing post 123. A spring 124 is fitted on the side wall between the fixing block 125 and the pressing post 123. The end of the connecting post 1210 is provided with a guide post 126 located below the fixing block 125 and inserted into the positioning seat 1212. A pair of stop posts 127 are symmetrically arranged on the side wall of the guide post 126. A guide hole 129 matching the guide post 126 is opened through the side wall of the positioning seat 1212. A positioning groove 1211 matching the stop post 127 is opened on the side wall of the positioning seat 1212 near the second base plate 122. The positioning groove 1211, the guide hole 129 and the annular stop groove 128 are connected to each other. This design applies force to the second guide seat 10, pressing the pressing post 123. The pressing post 123 causes the stop post 127 on the connecting post 1210 to lose contact with the annular stop groove 128. At this time, the spring 124 is compressed, and the second guide seat 10 is rotated. The rotation of the second guide seat 10 causes the second electrode assembly 6 on it to rotate. Under the action of the second connecting rod 74, multiple second guide seats 10 simultaneously rotate and tilt their second electrode assemblies 6. Then, the force applied to the second guide seat 10 stops, and the spring 124 rebounds, pushing the pressing post 123 to drive the connecting post 1210. 10. The connecting column 1210 drives the stop column 127 on the guide column 126 to fit into the annular stop groove 128. When it is necessary to rotate and tilt the second electrode assembly 6, the second crank 73 in the second drive mechanism 7 is moved to a suitable vertical position through the cooperation of the stop mechanism 9 and the drive lifting mechanism 8. The annular stop groove 128 is three-quarters of a circle. When the stop column 127 fits into the limit position of the inner wall of the annular stop groove 128, the second electrode assembly 6 is in a vertical state. When force is applied to multiple second guide seats 10, it can be pressed by multiple workers.

[0041] Reference Figure 8 and Figure 10 The second base plate 122 has a through hole on its side wall. The pressing post 123, connecting post 1210, spring 124, and fixing block 125 are all located inside the through hole. The diameter of the pressing post 123 matches the inner diameter of the through hole, and the diameter of the pressing post 123 is larger than the diameter of the connecting post 1210. The distance between the far ends of a pair of stop posts 127 is equal to the inner diameter of the annular stop groove 128. This improves the rationality of the design.

[0042] Reference Figures 1-10 As an embodiment of the present invention: when it is necessary to install the first electrode assembly 4 and the second electrode assembly 6, when the drive wheel 1001 and guide wheel 1003 of the tunneling machine traveling part 1 rotate, they drive the eccentric wheel shaft 21 and guide wheel shaft 27 to rotate. The eccentric wheel shaft 21 and guide wheel shaft 27 rotate with the drive wheel 1001 and guide wheel 1003 respectively, so as to drive the coupling 22 on them to drive the corresponding slide rod 24 to make a circular motion around the axis of the drive wheel 1001 and guide wheel 1003 respectively, and slide along the limiting slide groove 255 in the arc guide rail 25. When the slide rod 24 slides in the arc groove 252, the first connecting rod 26 remains horizontal; when the slide rod 24 moves to the first horizontal groove 254 or the second horizontal groove 254 at the connection of the upper and lower arc grooves 252, the slide rod 26 remains horizontal. When the tunnel 256 is level, the first connecting rod 26 generates a rapid vertical movement and moves laterally back and forth along the first electrode sleeve 41 in the multiple first electrode assemblies 4. The cooperation between the slide rod 24 and the arc-shaped guide rail 25 is converted into the vertical back and forth movement of the first connecting rod 26, which in turn drives the multiple first electrode assemblies 4 to periodically insert and pull out of the ground simultaneously. The arc-shaped guide rail 25 drives the multiple first electrode assemblies 4 on the first connecting rod 26 to move vertically synchronously back and forth, realizing the automatic deployment of electrodes as the tunnel is excavated. The automatic deployment of the first electrode assemblies 4 does not require frequent manual retrieval and re-deployment of electrodes. The electrode deployment is convenient and the operation is simple. It ensures that the electrodes have enough time to remain still after being inserted into the ground to improve measurement accuracy, and avoids shearing damage to the electrodes caused by the horizontal movement of the tunneling machine.

[0043] To ensure the required number of electrodes is met for generating the resistance cloud map and completing the detection, a pair of drive motors 72 in the second drive mechanism 7 rotate the second cranks 73. Under the action of the connecting shaft 75, the rotation of the second cranks 73 drives the second connecting rod 74 to move laterally back and forth along the connecting plate 63 in the multiple second electrode assemblies 6. At the same time, it drives the second electrode sleeve 61 in the multiple second electrode assemblies 6 to move the second electrode 62 on it vertically back and forth synchronously along the second guide seat 10, so that multiple second electrode assemblies 6 can be inserted into or removed from the ground at the same time, improving the convenience of deployment and simplifying the operation.
