[0029] The multi-directional buffer assembly 8 includes a positioning block 81 fixedly installed inside the connecting and fixing assembly 7. The positioning block 81 plays a positioning role. A connecting pipe 82 is fixedly installed inside the positioning block 81. The connecting pipe 82 is used to place lubricating oil to reduce the friction of the moving object. The two channel openings of the connecting pipe 82 are movably connected with piston rods 83. The piston rods 83 provide a buffering effect. One end of the piston rod 83 is movably connected with a ball 87. The ball 87 changes the friction between the drill rod 6 and the movable plate 84. One end of the positioning block 81 is rotatably connected with a concave rod 811. The top and bottom ends of the concave rod 811 are rotatably connected with rollers 812. The cooperation between the rollers 812 and the concave rod 811 is used to drive the two movable plates 84 to move relative to each other.

[0030] like Figure 2 and Figure 5 As shown, a movable plate 84 is fixedly mounted on one end of the piston column 83, a mounting bar 85 is symmetrically fixedly mounted on one end of the movable plate 84, a horizontal column 86 is fixedly mounted between the opposite surfaces of the two mounting bars 85, and a groove is formed on the opposite surfaces of the two horizontal columns 86, and a ball 87 is movably connected inside the groove;

[0031] The grooves are used to limit the ball 87 to prevent it from being offset when it rotates. The movable plate 84 is used to fix the mounting bar 85, the mounting bar 85 is used to fix the horizontal column 86, and the horizontal column 86 is used to fix the ball 87, so that the position of the overall structure can be displaced.

[0032] like Figure 2 and Figure 5 As shown, a spring telescopic rod 88 is symmetrically mounted on one end surface of the movable plate 84, and the spring telescopic rod 88 is fixedly mounted inside the connecting and fixing assembly 7;

[0033] The spring telescopic rod 88 can facilitate driving the movable plate 84 to reset, thereby reducing the difficulty of resetting the movable plate 84 .

[0034] like Figure 2 and Figure 5 As shown, the two end surfaces of the positioning block 81 are symmetrically welded with fixing bars 89, a round rod 810 is embedded and installed between the two fixing bars 89, and a concave rod 811 is rotatably connected to the outer side of the round rod 810;

[0035] The round rod 810 is fixed under the action of the fixing bar 89 , and the concave rod 811 can be rotated under the action of the round rod 810 , thereby changing the difficulty of rotating the concave rod 811 .

[0036] like Figure 2 and Figure 5 As shown, lubricating oil is provided inside the connecting pipe 82, and the roller 812 is composed of a hub and a rubber sleeve;

[0037] It is convenient to increase the friction between the roller 812 and the object, and under the action of the lubricating oil, the objects at both ends of the connecting tube 82 can move relatively.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, the connection and fixing assembly 7 includes a fixing ring 71 fixedly installed inside the rotary power device 4, an assembly ring 73 is installed on the outer surface of the fixing ring 71 through a thread, a spring rod 72 is embedded and installed inside the fixing ring 71, and the movable end of the spring rod 72 passes through the assembly ring 73;

[0039] Under the action of the spring rod 72, the assembly ring 73 can be restricted after moving outside the fixing ring 71, thereby preventing the assembly ring 73 from rotating due to inertia.

[0040] like Figure 3 and Figure 4 As shown, a receiving groove 77 is provided at the top of the assembly ring 73, and a second spring rod 75 is clamped and installed at the top of the assembly ring 73 at the inner position of the receiving groove 77. A same push ring 74 is fixedly installed between the tops of the plurality of second spring rods 75, and a push column 76 is embedded and installed at the bottom of the push ring 74;

[0041] The push ring 74 is pressed, and the push ring 74 drives the spring rod 2 75 to be compressed, and at the same time drives the push column 76 to move. When the push column 76 moves, it pushes the spring rod 1 72 to be compressed, so that the spring rod 1 72 is separated from the assembly ring 73, so that the assembly ring 73 cannot be resisted by the spring rod 1 72, and the assembly ring 73 can rotate.

[0042] like Figure 3 and Figure 4 As shown, the outer diameter of the bottom end of the push column 76 is equal to the outer diameter of the movable end of the spring rod 1 72, and the center lines of the spring rod 1 72 and the push column 76 are on the same vertical line;

[0043] It is convenient to push the spring rod 1 72 for compression, thereby changing the compression difficulty of the spring rod 1 72 .

[0044] like Figure 1 and Figure 2 As shown, the positioning block 81 is installed at the center of the inner wall of the fixing ring 71 at equal distances with the center point of the drill rod 6 as the reference, and the spring telescopic rod 88 is symmetrically arranged with the vertical and horizontal lines of the positioning block 81 as the reference, and the number ratio of the spring telescopic rod 88 to the positioning block 81 is four to one;

[0045] It is convenient to buffer and squeeze the periphery of the drill rod 6, thereby increasing the stability of the drill rod 6 when rotating, and further improving the drilling accuracy of the drill rod 6.

[0046] Working principle: Place the base 1 at the predetermined drilling position in the coal mine to ensure the stability and horizontality of the base 1, then install a vertical rod 9 on one side of the base 1, the vertical rod 9 plays a supporting and guiding role, then install a conductor seat at the top of the vertical rod 9, the conductor seat is internally movably connected with a wire rope, one end of the wire rope is connected to the top of the drill rod 6, and the other end is connected to a winch to control the lifting of the drill rod 6, then install a rotary power device 4 at one end of the vertical rod 9, then install a rotary power head 5 at the bottom of the rotary power device 4 to make it fixedly connected to the rotary power device 4, the rotary power head 5 is responsible for the drilling operation, and then A drill rod 6 is installed inside the head 5, and then a connection and fixing assembly 7 is installed at the top of the inner wall of the rotary power device 4 at the outer position of the drill rod 6, and then a multi-directional buffer assembly 8 is installed inside the connection and fixing assembly 7. The multi-directional buffer assembly 8 includes a positioning block 81, a connecting pipe 82, a piston column 83, a ball 87, a concave rod 811 and a roller 812. The positioning block 81 is fixedly installed inside the connection and fixing assembly 7 to play a positioning role. Then, the drill bit of the drill rod 6 is aligned with the target drilling point, and then the rotary power device 4 is started. The rotary power device 4 provides rotational power for the drill rod 6, so that the drill rod 6 starts to rotate to perform drilling operations;

[0047] According to the drilling depth and geological conditions, the wire rope is retracted and released by the winch to realize the lifting and lowering of the drill rod 6. During the descent of the drill rod 6, the drill rod 6 drives the ball 87 to roll in the groove of the horizontal column 86. When the drill rod 6 is subjected to a lateral force, the ball 87 contacts the drill rod 6. At this time, the drill rod 6 tilts and drives the ball 87 to move. When the ball 87 moves, it drives the moving plate 84 to move through the mounting bar 85 and the horizontal column 86. When the moving plate 84 moves, it drives the piston column 83 to move in the connecting pipe 82. At this time, the other piston column 83 is pushed to move by the action of the lubricating oil inside the connecting pipe 82. At this time, the piston column 83 moves through the moving plate 84, the mounting bar 85 and the horizontal column 86. 6 drives the ball 87 to squeeze the drill rod 6. At this time, the rolling of the ball 87 changes the friction between the drill rod 6 and the movable plate 84, so that the drill rod 6 can more flexibly cope with the lateral force. At the same time, the spring telescopic rod 88 is extended and retracted under the drive of the movable plate 84, further providing a buffering and shock absorbing effect, ensuring the stability and drilling accuracy of the drill rod 6, thereby effectively compensating for the lateral force of the drill rod 6, so that the drill rod 6 remains stable and is not easy to shake, thereby improving the drilling accuracy, and balancing the roll of the immersed drill rod 6, ensuring the straightness of the drilling direction, effectively improving the drilling accuracy, and reducing the influence of the lateral force, so that the drill rod 6 can move more smoothly, thereby improving the drilling efficiency;

[0048] At the same time, the two movable plates 84 are driven to move relative to each other with the cooperation of the concave rod 811 and the roller 812. When the drill rod 6 is subjected to forces in different directions, the roller 812 rotates driven by the concave rod 811, thereby driving the movable plate 84 to move, so that the multi-directional buffer assembly 8 can buffer and shock the drill rod 6 from multiple directions. Through shock absorption and buffering, the impact and vibration of the drill rod 6 are effectively reduced, thereby extending the service life of the drill rod 6.

[0049] When the connection and fixing assembly 7 needs to be adjusted or disassembled, the push ring 74 is pressed, and the push ring 74 drives the spring rod 2 75 to be compressed, and at the same time drives the push column 76 to move. When the push column 76 moves, it pushes the spring rod 1 72 to be compressed, so that the spring rod 1 72 is separated from the assembly ring 73, so that the assembly ring 73 cannot be resisted by the spring rod 1 72, and then the assembly ring 73 can be rotated, which is convenient for operating the connection and fixing assembly 7. Through the coordinated action of the spring rod and the push ring 74, the connection and fixing assembly 7 is quickly and conveniently operated, thereby improving work efficiency.

[0050] When the drilling reaches the predetermined depth or the drilling task is completed, the operation of the rotary power device 4 is stopped to stop the rotation of the drill rod 6. At this time, the winch is started to slowly recover the drill rod 6 from the borehole to the initial position through the wire rope.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
