Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-5 As shown, a multifunctional mining tunnel milling machine comprises a workbench 1, a main working arm 2, an auxiliary working arm 3 and an installation box 4: the main working arm 2 is installed on the side of the workbench 1, the auxiliary working arm 3 is installed below the main working arm 2, the installation box 4 is installed below the auxiliary working arm 3, a driving control mechanism 5 is arranged inside the installation box 4, a monitoring control mechanism 6 is arranged on the side of the driving control mechanism 5, and a heat dissipation control mechanism 7 is arranged above the monitoring control mechanism 6. The driving control mechanism 5 comprises a limiting partition 51, a driving motor 52, a transmission shaft 53, a positioning plate 54, a first Threaded hole 55, mounting plate 56, milling cutter 57, second threaded hole 58 and positioning bolt 59, the inner wall of the bottom end of the mounting box 4 at the middle position is provided with a limited partition plate 51, and the outer walls on both sides of the limited partition plate 51 are symmetrically installed with driving motors 52, the driving motor 52 is connected to one end of the transmission shaft 53, and the other end of the transmission shaft 53 is connected to the positioning plate 54, and the positioning plate 54 is rotatably installed with the side outer wall of the mounting box 4, and the side outer wall of the positioning plate 54 is surrounded by a first threaded hole 55 with equal spacing, and the side of the positioning plate 54 is provided with a mounting plate 56, and the mounting plate A milling cutter 57 is provided on the side outer wall of 56, and a second threaded hole 58 is opened in a circumferential manner at an equal interval on the side outer wall of the mounting plate 56. The first threaded hole 55 and the second threaded hole 58 are equal in shape and size, and the first threaded hole 55 and the second threaded hole 58 are threadedly installed with the positioning bolt 59; when it is necessary to control the operation of the milling cutter 57 to perform tunnel milling, it is necessary to first control the drive motor 52 to start. When the drive motor 52 is turned on, it will automatically drive the transmission shaft 53 to rotate and then drive the positioning plate 54 to rotate, and then the rotation of the positioning plate 54 will automatically drive the mounting plate 56 to rotate. The mounting plate 56 rotates to drive the milling cutter 57 to rotate, and then the control device adjusts the main working arm 2 and the auxiliary working arm 3 to move the milling cutter 57 to a suitable position for operation. When the milling cutter 57 is worn and needs to be replaced, it is only necessary to unscrew the positioning bolts 59 from the outside of the second threaded hole 58 in turn. When installing a new milling cutter 57, it is only necessary to adjust the mounting plate 56 to make the second threaded holes 58 correspond to the first threaded holes 55 on the outside of the positioning plate 54 one by one, and then pass the positioning bolts 59 through the second threaded holes 58 and screw them into the inside of the first threaded holes 55.

[0024] The monitoring and control mechanism 6 includes a driving gear 61, a driven gear 62 and a protective cover 63. The driving gear 61 is arranged on the outside of the transmission shaft 53, and the driven gear 62 is meshed and installed on the side of the driving gear 61. The driving gear 61 and the driven gear 62 are both arranged inside the protective cover 63, and the protective cover 63 is connected to the inner wall of the side of the installation box 4. The driven gear 62 is arranged on the outside of the control shaft 64, and one end of the control shaft 64 is connected to the inner wall of the side of the protective cover 63, and the other end of the control shaft 64 is connected to the speed monitoring sensor 65, and the speed monitoring sensor 65 is connected to the inner wall of the side of the protective cover 63; when the above-mentioned transmission shaft 53 rotates, it will automatically drive the driving gear 61 to rotate, and then the rotation of the driving gear 61 will automatically drive the driven gear 62 to rotate, and then the driven gear When the speed of the milling cutter 57 is lower than the monitoring interval set by the speed monitoring sensor 65, it indicates that the milling cutter 57 may be stuck or have other abnormal problems. It is noted that the speed monitoring sensor 65 needs an external output terminal to facilitate the staff to observe the monitoring data of the speed monitoring sensor 65 in time. When the staff observes that the speed monitoring sensor 65 report is abnormal, the control device can be stopped in time for maintenance.

[0025] The heat dissipation control mechanism 7 includes a temperature monitoring sensor 71 and a mounting frame 72. The temperature monitoring sensor 71 is arranged on the inner wall of the side of the mounting box 4. The mounting frames 72 are symmetrically arranged on the inner walls of both sides of the mounting box 4. The inner wall of the mounting frame 72 is installed with a condenser 73. The top inner wall of the mounting box 4 is provided with a support cover 74, and the support cover 74 is in contact with the outer wall of the side of the mounting frame 72. The bottom inner wall of the support cover 74 is provided with a controller 75. The side of the controller 75 is provided with a power supply 76, and the power supply 76 is connected to the inner wall of the bottom end of the support cover 74. Since the driving motor 52 will continuously dissipate heat when it is working, when the temperature inside the mounting box 4 exceeds the monitoring value set by the temperature monitoring sensor 71, the temperature monitoring sensor 71 will automatically transmit the information to the controller 75, and then the controller 75 will automatically control the power supply 76 to start powering the condenser 73. It is noted here that the setting of the mounting frame 72 has the effect of auxiliary support installation for the condenser 73, and then the condenser 73 is powered on to supply cooling, which will cool down the inside of the mounting box 4.

[0026] When the utility model is in use, when it is necessary to control the operation of the milling cutter 57 to perform tunnel milling, it is first necessary to control the drive motor 52 to start. When the drive motor 52 is turned on, it will automatically drive the transmission shaft 53 to rotate and then drive the positioning plate 54 to rotate. Then, the rotation of the positioning plate 54 will automatically drive the mounting plate 56 to rotate and then drive the milling cutter 57 to rotate. Then, the control device adjusts the main working arm 2 and the auxiliary working arm 3 to move the milling cutter 57 to a suitable position for operation. When the milling cutter 57 needs to be replaced after being worn, it is only necessary to sequentially remove the positioning bolts 59 from the outer sides of the second threaded hole 58. When installing a new milling cutter 57, it is only necessary to adjust the mounting plate 56 until the second threaded holes 58 correspond to the first threaded holes 55 on the outside of the positioning plate 54 one by one, and then screw the positioning bolts 59 through the second threaded holes 58 into the inside of the first threaded holes 55; when the transmission shaft 53 rotates, it will automatically drive the driving gear 61 to rotate, and then the driving gear 61 will automatically drive the driven gear 62 to rotate, and then the driven gear 62 will automatically drive the control shaft 64 to rotate. The setting of the protective cover 63 here serves as a limit support for the control shaft 64 The speed monitoring sensor 65 is provided to facilitate real-time monitoring of the speed of the control shaft 64. Since the speed of the milling cutter 57 directly reflects the speed of the transmission shaft 53, and the speed of the transmission shaft 53 is consistent with the speed of the control shaft 64, once the speed of the control shaft 64 is lower than the monitoring interval set by the speed monitoring sensor 65, it indicates that the milling cutter 57 may be stuck or have other abnormal problems. It is noted that the speed monitoring sensor 65 needs an external output terminal to facilitate the staff to observe the monitoring data of the speed monitoring sensor 65 in time. When the staff observes that the speed monitoring sensor 65 report is abnormal, the device can be controlled to stop operating for maintenance in time. Since the drive motor 52 will continuously dissipate heat during operation, when the temperature inside the installation box 4 exceeds the monitoring value set by the temperature monitoring sensor 71, the temperature monitoring sensor 71 will automatically transmit the information to the controller 75, and then the controller 75 will automatically control the power supply 76 to start powering the condenser 73. It is noted that the setting of the installation frame 72 has the effect of auxiliary support installation for the condenser 73, and then the condenser 73 is powered on for cooling, which will cool the inside of the installation box 4.

[0027] It is noted here that the driving motor 52 can be powered by the existing technology, and it belongs to the existing technology and will not be described in detail here.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
