[0003] The core purpose of controlling mining force is to ensure operational safety and improve efficiency while avoiding systemic risks caused by uncontrolled force. If the mining force is not controlled, the internal stress of the rock or soil will be released unevenly due to the mining behavior. Especially in areas with complex geological conditions, sudden changes in force can easily lead to stress concentration, and then cause accidents such as collapse and spalling. Therefore, the present invention proposes a mining force control device. Summary of the Invention

[0026] The beneficial effect of the present invention is that when the drill head at the first end is working, the sliding table slides to the first position, and at this time the power of the driving part is transmitted to the first rotating part through the first transmission part, so that the first rotating part works, and the first rotating part can drive the drill head to make the drill head work, excavate the mining area, and obtain a borehole.

[0033] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0034] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0035] Reference Figure 1 This embodiment provides a mining force control device, including a shell 100; the shell 100 is a long strip structure, which is convenient for drilling in the mining area. The two ends of the shell 100 are divided into a first end 101 and a second end 102. In this embodiment, the first end 101 and the second end 102 play different roles. The first end 101 is mainly used for drilling, and the second end 102 is mainly used for detecting stress. Ultimately, the mining force is controlled by the results of the stress detection.

[0036] The device also includes a drill head 200, which is arranged at one end of the shell 100. In this embodiment, the drill head 200 is installed at the first end 101 of the shell 100. When the drill head 200 rotates, it can drill holes in the land in the mining area, thereby completing the drilling work.

[0037] The device also includes a pushing portion 300, which is provided at the other end of the shell 100. In this embodiment, the pushing portion 300 is located at the second end 102 of the shell 100. After the drilling is completed, the strain gauge is placed at the second end 102 of the shell 100, and the pushing portion 300 works to send the strain gauge into the interior of the hole, thereby performing stress detection.

[0038] The device also includes a first rotating part 400 and a second rotating part 500, both of which are installed inside the shell 100 and are connected to the drill part 200 and the pushing part 300 respectively; in this embodiment, the first rotating part 400 is used to drive the drill part 200, and the second rotating part 500 is used to drive the pushing part 300. When the first rotating part 400 rotates, it can drive the drill part 200 to work, so that the drill part 200 can perform hole drilling operations. When the drilling is completed, the first end 101 is removed from the hole, and then the second end 102 is inserted into the inside of the hole. The pushing part 300 is driven to move by the second rotating part 500, so that the pushing part 300 presses the stress gauge into the hole, thereby measuring the stress in the mining area through the stress gauge.

[0039] The device also includes a sliding platform 600, which can be slidably mounted on the housing 100; a driving part 700, which is mounted on the sliding platform 600; a first transmission part 800 and a second transmission part 900, both of which are connected to the driving part 700, and the first transmission part 800 and the second driving part 700 are both transmission-connected to the driving part 700; the sliding platform 600 can switch between a first position and a second position. When the sliding platform 600 is in the first position, the first transmission part 800 can drive the first rotating part 400. When the sliding platform 600 is in the second position, the second transmission part 900 can drive the second rotating part 500.

[0040] Therefore, when the drill head 200 at the first end 101 is working, the sliding table 600 is slid to the first position. At this time, the power of the driving part 700 is transmitted to the first rotating part 400 through the first transmission part 800, so that the first rotating part 400 works. The first rotating part 400 can drive the drill head 200, so that the drill head 200 works, excavates the mining area, and obtains a borehole.

[0041] After the drilling is completed, the first end 101 is taken out and the second end 102 is directed toward the borehole. At this time, the sliding table 600 is slid to the second position, and the power of the driving part 700 is transmitted to the second rotating part 500 through the second transmission part 900. The second rotating part 500 works, and the second rotating part 500 can drive the pushing part 300. The pushing part 300 pushes the stress gauge toward the bottom of the borehole, and presses the stress gauge against the bottom of the borehole, thereby obtaining stress data of the mining area, and controlling the mining force according to the stress data.

[0042] When the stress is low, speed up the mining process and adopt a rapid advancement mode to reduce the exposure time of the coal seam and reduce stress accumulation. When the stress is too high, reduce the mining process and increase the support working resistance to avoid sudden stress increases.

[0043] The first rotating part 400 includes a first rotating shaft 401 and a connecting member 402 connecting the first rotating head and the drill head 200. A bearing-like structure is provided inside the shell 100. The first rotating shaft 401 can be rotatably installed inside the shell 100 through the bearing-like structure. Both ends of the connecting member 402 have a threaded connection structure. The two ends of the connecting member 402 are respectively connected to the drill head 200 and the first rotating shaft 401 through the threaded connection structure. Therefore, when the first rotating shaft 401 is driven by the first transmission part 800, the first rotating shaft 401 can drive the drill head 200 to rotate synchronously through the connecting member 402.

[0044] The second rotating part 500 includes a second rotating shaft 501, and a threaded section 502 is provided on the second rotating shaft 501. The second rotating shaft 501 is rotatably installed inside the shell 100 through a bearing-like structure. The threaded section 502 is used to connect the pushing part 300. When the second rotating shaft 501 rotates, the pushing part 300 can be driven to move linearly through the threaded section 502. For example, when the threaded section 502 rotates clockwise, the pushing part 300 can be driven to move toward the second end 102. When the threaded section 502 rotates counterclockwise, the pushing part 300 can be driven to move away from the second end 102. The pushing part 300 moving toward the second end 102 can push the strain gauge. When the pushing part 300 moves away from the second end 102, it can be reset.

[0045] The pushing portion 300 includes a threaded tube 301 connected to the second rotating shaft 501, and a push platform 302 installed on the threaded segment 502. The threaded tube 301 is connected to the second rotating shaft 501 through the threaded segment 502. In this embodiment, the push platform 302 can be slidably installed inside the shell 100 through a slide groove and a slider-like structure. Therefore, the push platform 302 cannot rotate but can only slide. Therefore, when the threaded segment 502 of the second rotating shaft 501 rotates, it cannot drive the threaded tube 301 to rotate. Under the action of the thread, the threaded tube 301 moves relative to the shell 100. By controlling the rotation direction of the second rotating shaft 501, the movement direction of the push platform 302 can be controlled.

[0046] The first transmission part 800 includes a first gear 801 installed on the first rotating part 400, and a second gear 802 connected to the driving part 700 and moving synchronously with the driving part 700. The second transmission part 900 includes a third gear 901 installed on the second rotating part 500, and a fourth gear 902 connected to the driving part 700 and moving synchronously with the driving part 700.

[0047] When the slide is in the first position, the first gear 801 is engaged with the second gear 802. At this time, the power of the driving part 700 can be transmitted to the first rotating part 400 through the first transmission part 800. Specifically, the first gear 801 is installed on the first rotating shaft 401, and the second gear 802 is connected to the driving part 700. When the first gear 801 and the second gear 802 are engaged, the driving part 700 drives the second gear 802 to rotate, and the second gear 802 drives the first gear 801 and the first rotating shaft 401 to rotate, thereby transmitting power to the drill head 200, so that the drill head 200 rotates and works.

[0048] When the slide is in the second position, the third gear 901 and the fourth gear are engaged. At this time, the power of the driving part 700 can be transmitted to the second rotating part 500 through the second transmission part 900. Specifically, the third gear 901 is installed on the second rotating shaft 501, and the fourth gear 902 is connected to the driving part 700. When the third gear 901 and the fourth gear 902 are engaged, the driving part 700 drives the fourth gear 902 to rotate, and the fourth gear 902 drives the third gear 901 and the second rotating shaft 501 to rotate, thereby transmitting power to the pushing part 300, so that the pushing part 300 works.

[0049] The sliding table 600 includes a ring 601 that is slidably connected to the shell 100, and a mounting platform 602 installed on the ring 601. The interior of the ring 601 fits the outer surface of the shell 100, and the ring 601 can slide relative to the sliding table 600. The mounting platform 602 is directly fixed on the ring 601. When the ring 601 moves, it can drive the mounting platform 602 to move synchronously. In this embodiment, the role of the ring 601 is to help the sliding table 600 be installed as a whole on the shell 100, and the role of the mounting platform 602 is to permanently install the driving part 700.

[0050] The driving unit 700 includes a power member 701 mounted on the mounting platform 602. In this embodiment, the power member 701 is a driving motor. The power member 701 is directly mounted on the mounting platform 602. When the sliding platform 600 moves, it can drive the power member 701 to move synchronously.

[0051] The driving part 700 includes a first rotating body 702, a second rotating body 703, and a driving bevel gear 704 connected to the output shaft of the power part 701; the first transmission part 800 also includes a first bevel gear 803 installed on the first rotating body 702; the second transmission part 900 also includes a second bevel gear 903 installed on the second rotating body 703; the driving bevel gear 704 is engaged with the first bevel gear 803 and the second bevel gear 903.

[0052] In this embodiment, the first rotating body 702 and the second rotating body 703 are both annular structures, the first bevel gear 803 and the second gear 802 are both installed on the first rotating body 702, and the first bevel gear 803 and the second gear 802 rotate synchronously through the first rotating body 702, the second bevel gear 903 and the fourth gear 902 are both installed on the second rotating body 703, and the second bevel gear 903 and the second gear 802 rotate synchronously through the second rotating body 703.

[0053] It should be further explained that the first rotating body 702, the second rotating body 703, the first bevel gear 803, the second bevel gear 903, the second gear 802 and the third gear 901 all move synchronously with the slide. Therefore, no matter how the slide 600 moves, the driving bevel gear 704 and the first bevel gear 803 and the second bevel gear 903 are in a meshing state.

[0054] The sliding platform 600 is also provided with a first mounting ring 603 and a second mounting ring 604, the first rotating body 702 is installed on the first mounting ring 603, and the second rotating body 703 is installed on the second mounting ring 604; the interior of the shell 100 is also provided with a rotating central axis 10, and the first rotating body 702 and the second rotating body 703 are both slidably arranged on the rotating central axis 10.

[0055] Through the first mounting ring 603 and the second mounting ring 604, the first rotating body 702 and the second rotating body 703 can move synchronously with the slide, so that the first rotating body 702, the second rotating body 703, the first bevel gear 803, the second bevel gear 903, the second gear 802 and the third gear 901 all move synchronously with the slide.

[0056] Moreover, in this embodiment, the rotating central axis 10 can be rotatably connected to the first rotating axis 401 and the second rotating axis 501. In addition, the rotating central axis 10 can also be directly rotatably installed inside the shell 100 without contacting the first rotating axis 401 and the second rotating axis 501. In addition, the rotating central axis 10, the first rotating axis 401 and the second rotating axis 501 are preferably coaxial.

[0057] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
