DETAILED DESCRIPTION

[0025] The embodiment of the present invention provides a navigation and positioning auxiliary device for an unmanned mining vehicle, such as Figure 1-5 As shown, it includes a connecting seat 11, a screw 12, a radar base 13, a first cavity 14, an adjustment part base 15, a slider 16, a limit block 20, a rotating rod 21, a swing arm 22, a radar 23, a first sliding rod 26, a second cavity 27, a second sliding rod 28, a first spring 29, a horizontal reset part base 30, a third cavity 31, a positioning shaft 32, a horizontal reset plate 33, a second spring 34, a guide shaft 35, a pull rope 36, an adjustment part connecting block 40, a cam 41, and a motor 42.

[0026] like Figure 1-3 As shown, it includes a connecting seat 11, a signal transceiver device and an adjusting device. A radar base 13 is fixedly arranged on the connecting seat 11. The signal transceiver device includes an adjusting portion base 15, a swing arm 22 and a radar 23. Two limit blocks 20 are fixedly arranged on the adjusting portion base 15. A rotating rod 21 is fixedly connected between the two limit blocks 20. A torsion spring is arranged between the limit block 20 and the swing arm 22. The swing arm 22 is rotatably connected to the rotating rod 21. The radar 23 is fixedly connected to the swing arm 22. The radar base 13 is close to the adjusting portion. Two first cavities 14 are provided at one end of the adjusting part base 15, and sliders 16 are fixedly connected to the two ends of the adjusting part base 15 close to the radar base 13. The slider 16 is slidably connected to the first cavity 14. The adjusting device includes a driving component and a reset component. The driving component drives the adjusting part base 15 to move in the vertical direction. A groove is provided on one side surface of the adjusting part base 15 close to the driving component. A plurality of screws 12 are provided on the connecting seat 11, and the screws 12 are used to fix the connecting seat 11 on the mining unmanned vehicle.

[0027] like Figure 2 As shown, a horizontal reset portion base 30 is fixedly provided on the connecting seat 11, and a driving assembly includes an adjusting portion connecting block 40, a cam 41 and a motor 42. The adjusting portion connecting block 40 is fixedly connected to the outer circumferential surface of the horizontal reset portion base 30, and an opening is provided at one end of the adjusting portion connecting block 40 away from the horizontal reset portion base 30. The output shaft of the motor 42 is rotatably connected to the opening of the adjusting portion connecting block 40, and the output shaft of the motor 42 is fixedly connected to the cam 41. The cam 41 is used to drive the adjusting portion base 15 to move in a vertical direction.

[0028] The cam 41 is driven by the motor 42 to rotate around the output shaft of the motor 42 . When the cam 41 rotates to the upper limit position of the cam 41 , the raised part of the cam 41 pushes the adjusting part base 15 upward, so that the adjusting part base 15 moves in the vertical direction and the slider 16 and the first cavity 14 slide upward relative to each other.

[0029] like Figure 4-5As shown, the reset assembly includes a vertical reset assembly and a horizontal reset assembly. The vertical reset assembly includes a first sliding rod 26 and a second sliding rod 28. A second cavity 27 is opened in the first sliding rod 26. The second sliding rod 28 is slidably connected to the second cavity 27. One end of the second sliding rod 28 away from the first sliding rod 26 is fixedly connected to the adjustment part base 15, and one end of the first sliding rod 26 away from the second sliding rod 28 is fixedly connected to the radar base 13. A first spring 29 is arranged in the second cavity 27, one end of the first spring 29 is fixedly connected to the second sliding rod 28, and the other end of the first spring 29 is fixedly connected to the second cavity 27.

[0030] When the cam 41 rotates to the lower limit position of the cam 41, the first spring 29 generates a pulling force on the second sliding rod 28, and the second sliding rod 28 generates a pulling force on the adjusting portion base 15, so that the adjusting portion base 15 moves downward, and the slider 16 and the first cavity 14 slide downward relative to each other, thereby completing the vertical resetting of the adjusting portion base 15.

[0031] The horizontal reset assembly includes a horizontal reset plate 33 and a pull rope 36, one end of the pull rope 36 is fixedly connected to the horizontal reset plate 33, and the other end of the pull rope 36 is fixedly connected to the outer spherical surface of the radar 23. A third cavity 31 is opened in the horizontal reset base 30, and a second spring 34 is arranged in the third cavity 31. One end of the second spring 34 is fixedly connected to the horizontal reset plate 33, and the other end of the second spring 34 is fixedly connected to the third cavity 31. Two positioning shafts 32 are fixedly connected to the outer circumferential surface of the third cavity 31, and a guide shaft 35 is rotatably connected between the two positioning shafts 32. A circular groove is arranged on the guide shaft 35, and the pull rope 36 is slidably connected to the circular groove of the guide shaft 35.

[0032] When the cam 41 rotates to the upper limit position, the cam 41 drives the adjusting portion base 15 to move upward, and the radar 23 moves upward with the adjusting portion base 15. Since the pull rope 36 is fixedly connected to the radar 23, and the pull rope 36 is fixedly connected to the horizontal reset plate 33, the second spring 34 generates a pulling force on the horizontal reset plate 33. Through the pulling force of the second spring 34 on the horizontal reset plate 33, the horizontal reset plate 33 generates a pulling force on the pull rope 36, and the pull rope 36 generates a pulling force on the radar 23, so that the radar 23 rotates in the pulling direction of the pull rope 36. Since a torsion spring is arranged between the limit block 20 and the swing arm 22, the restoring force of the torsion spring on the swing arm 22 is equal to the pulling force of the pull rope 36 on the radar 23 at this time.

[0033] When the cam 41 rotates to the lower limit position, the adjusting portion base 15 moves downward due to the pulling force of the vertical reset assembly, and the radar 23 moves downward along with the adjusting portion base 15. The pulling force of the pull rope 36 on the radar 23 disappears, and since a torsion spring is arranged between the limit block 20 and the swing arm 22, the torsion spring generates a restoring force on the swing arm 22, so that the swing arm 22 drives the radar 23 to reset.

[0034] When the scheme is used to assist the navigation and positioning of the unmanned mining vehicle, first, the motor 42 is started, and the cam 41 is driven by the motor 42 to rotate with the drive shaft of the motor 42 as the axis. Then, when the cam 41 rotates to the upper limit position, the cam 41 drives the adjustment unit base 15 to move upward, and the second spring 34 generates a pulling force on the horizontal reset plate 33. The pulling force of the second spring 34 on the horizontal reset plate 33 causes the horizontal reset plate 33 to generate a pulling force on the pull rope 36, and the pull rope 36 generates a pulling force on the radar 23, thereby causing the radar 23 to rotate in the pulling direction of the pull rope 36. Finally, when the cam 41 rotates to the lower limit position, the adjustment unit base 15 moves downward due to the pulling force of the vertical reset assembly, and the radar 23 moves downward with the adjustment unit base 15. The pulling force of the pull rope 36 on the radar 23 disappears, and the restoring force of the torsion spring on the swing arm 22 causes the swing arm 22 to drive the radar 23 to reset.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
