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.

[0021] See also Figure 1-3 The utility model provides an embodiment: a high-efficiency drill rod transmission device for a coal mine drilling rig, comprising a mounting bin 2, a mounting outer sleeve 11 and a mounting inner tube 13, a through slot 10 being provided at one end of the mounting bin 2, and a control panel 3 being installed at the bottom of the mounting bin 2 away from the through slot 10, a servo motor 1 being installed at the bottom of the mounting bin 2, wherein the model of the servo motor 1 here may be MR-J2S-10A, and a threaded rod 5 extending into the interior of the mounting bin 2 is installed at the output end of the servo motor 1, a threaded tube 7 is installed on the outer thread of the threaded rod 5, and a transmission plate 12 is installed at one end of the threaded tube 7 close to the through slot 10, the transmission plate 12 passes through the through slot 10, and a mounting outer sleeve 11 is installed at one end of the transmission plate 12 away from the threaded tube 7, an mounting inner tube 13 is installed inside the mounting outer sleeve 11, and a second ball groove 16 is provided on the outer side of the mounting inner tube 13.

[0022] In this implementation:

[0023] Furthermore, a first ball groove 15 is provided on the inner side of the mounting outer sleeve 11, and balls 17 are evenly installed inside the first ball groove 15. When in use, the drill rod is installed inside the mounting inner tube 13, and the mounting inner tube 13 can rotate inside the mounting outer sleeve 11 through the balls 17, so that the mounting inner tube 13 can rotate with the drill rod without affecting the mounting outer sleeve 11.

[0024] Furthermore, a group of fixing screw holes 19 are symmetrically arranged on the outer side of the installation inner tube 13, and the inside of the fixing screw holes 19 are all threadedly installed with fixing bolts 14, and the fixing bolts 14 are all installed with fixing clamps 18 at one end close to the installation inner tube 13. The drill rod is placed inside the installation inner tube 13, and the two groups of fixing bolts 14 are rotated so that the fixing bolts 14 move inside the fixing screw holes 19 through threads, and the fixing bolts 14 drive the fixing clamps 18 to move together, so that the fixing clamps 18 are tightly fitted with the outer side of the drill rod, and the drill rod can be clamped by the two groups of fixing clamps 18.

[0025] Furthermore, a sliding assembly 4 is installed at one end of the installation bin 2 away from the through groove 10, and a guide slider 6 is slidably installed at one end of the sliding assembly 4 close to the through groove 10. The end of the guide slider 6 away from the sliding assembly 4 is connected to the threaded tube 7.

[0029] Working principle:

[0030] When in use, the device is powered on, and then the drill rod is placed inside the installation inner tube 13, and the two sets of fixing bolts 14 are rotated so that the fixing bolts 14 move inside the fixing screw holes 19 through the threads, and the fixing bolts 14 drive the fixing clamps 18 to move together, so that the fixing clamps 18 are tightly fitted with the outer side of the drill rod, and the drill rod can be clamped by the two sets of fixing clamps 18;

[0031] During use, the installation inner tube 13 can rotate inside the installation outer sleeve 11 through the ball 17, so that the installation inner tube 13 can rotate with the drill rod without affecting the installation outer sleeve 11;

[0032] When the rotating rod is driven, the staff can start the servo motor 1 through the control panel 3, so that the servo motor 1 drives the threaded rod 5 to rotate clockwise or counterclockwise, and the threaded tube 7 outside the threaded rod 5 is limited by the guide slider 6, so that the threaded tube 7 cannot rotate with the threaded rod 5, so that the threaded tube 7 can only move outside the threaded rod 5 through the thread;

[0033] At this time, the threaded tube 7 drives the guide slider 6 to slide along a straight line on the sliding assembly 4, and the threaded tube 7 drives the installation outer sleeve 11 to move together through the transmission plate 12, which can drive the drill rod to move and play the effect of transmitting the drill rod.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
