[0053] Combined with the attached drawings of the specification Figures 1-6 As shown in the figure, during use, the embedded sleeve 9 is embedded inside the second guiding block 4, as Figures 3-4As shown, during installation and use, the inner layer of the guide sleeve 10 is contracted by gluing, so that the straightening frame 11 and the positioning clamp 13 are contracted inwardly, and the guide sleeve 10 is inserted into the interior and then released, so that the guide sleeve 10 pushes the rod body at one end of the straightening frame 11 and the positioning clamp 13 to abut against the end of the telescopic airbag 12. When the anchor rod body 1 is inserted into the guide sleeve 10 and tilts, the straightening frame 11 or any side of the positioning clamp 13 is pushed, so that the rod body at one end of the positioning clamp 13 or the rod body at one end of the straightening frame 11 squeezes the internal gas of the telescopic airbag 12 to the other end Push, thereby pushing the positioning clamp 13 or the straightening frame 11 on the same side to move toward the guide sleeve 10, pushing the end of the anchor rod body 1 to move to one side to straighten and maintain stability, so that the end of the anchor rod body 1 moves toward the middle opening of the limit block 6, and the limit block 6 provides support and stability for the installation position of the inner nesting tube 9 and the guide sleeve 10. A spring structure is installed between the positioning clamp 13 and the inner nesting tube 9.

[0054] The guide components include:

[0055] An auxiliary bearing 14 is installed inside the hole of the guide block 1 3, and the bottom end of the auxiliary bearing 14 abuts against the top end of the guide block 2 4;

[0056] The guide inner tube 15 is sleeved inside the auxiliary bearing 14, and the guide inner tube 15 is nested inside the hole of the guide block 3, the upper end of the guide inner tube 15 is set as a bowl-shaped structure, and the guide inner tube 15 and the blocking ring 19 are sleeved and installed, and the guide inner tube 15 and the auxiliary bearing 14 are sleeved inside the guide block 3;

[0057] The limiting ring 16 is installed inside the upper end of the guide inner tube 15, and the inner wall surface of the limiting ring 16 is flush with the inner wall surface of the guide inner tube 15. The upper end of the limiting ring 16 is set as 4 arc-shaped plate structures, and the limiting ring 16 and the stabilizing ring 18 are set as a work-shaped structure;

[0058] The bellows 17 is sleeved between the guide inner tube 15 and the limit ring 16, and the bottom end of the bellows 17 is installed with the top end of the inner wall of the guide inner tube 15;

[0059] A stabilizing ring 18 is installed at the top of the bellows 17, and the interior of the stabilizing ring 18 is penetrated by the limiting ring 16;

[0060] In conjunction with the accompanying drawings Figures 1-6 As shown, with the auxiliary bearing 14 placed in the inner hole of the guide block 3, as shown in FIG. Figures 3-4As shown, the guide inner tube 15 nested in the inner layer of the auxiliary bearing 14 directly contacts the anchor body 1 and rotates synchronously. When the anchor body 1 descends into the hole set in the project, it rotates in coordination with the auxiliary bearing 14 to prevent the rotation of the auxiliary bearing 14 from affecting the stability of the installation position of the guide block 1 3 and the guide block 2 4. The limit ring 16 is set at the upper end of the guide inner tube 15, as shown in FIG. Figures 3-4 As shown, the stabilizing ring 18 passes through the top of the limiting ring 16. After entering the top of the anchor rod body 1, the stabilizing ring 18 drives the anchor rod body 1 to enter the port and steadily descend through the limiting ring 16 to enter the pipeline of the guide inner tube 15, maintaining the stability of the insertion position of the anchor rod body 1. The bellows 17 arranged at one end of the stabilizing ring 18 moves synchronously and cooperates with the lifting and lowering activities of the stabilizing ring 18, effectively reducing the deviation of the drill rod during the drilling process and guiding it into the guide sleeve 10 inside the guide block 24 below, so that the accurate drilling trajectory of the anchor rod body 1 and the stable operation of the drill rod help to ensure the installation quality of the anchor cable.

[0061] Working principle: When using the anchor drill rod guide device with an embedded stabilizing structure, the positioning plate 2, the guide block 1 3 and the guide block 2 4 are installed in sequence to form a main body installed in the direction of the hole position of the diversion hole construction, and the external positioning metal frame structure is connected to the top of the positioning plate 2. As the anchor rod body 1 is inserted and abutted against the inner wall surface of the stabilizing ring 18, the stabilizing ring 18 drives the bellows 17 to move during the process of pushing the anchor rod body 1 down, and guides the anchor rod body 1 to pass through the guide inner tube 15 and enter the guide sleeve 10. The rotation of the anchor rod body 1 during the descent process drives the guide inner tube 15 to rotate in coordination with the inner layer of the auxiliary bearing 14. The bearing setting of the auxiliary bearing 14 avoids excessive displacement of the anchor rod body 1 during the rotation process, so that the anchor rod body 1 is accurately introduced into the guide sleeve 10. When the anchor body 1 inserted into the guide sleeve 10 is tilted to one side, it squeezes the positioning splint 13 or one end of the straightening frame 11, so that the squeezed internal gas at any end of the E-shaped pipe of the bellows 17 moves to the pipe of the other port, pushing another limiting guide sleeve 10 position, maintaining the temperature and humidity of the other end of the anchor body 1 during operation, reducing repeated drilling and correction work due to drill rod deflection, and as the limit block 6 and the auxiliary inner ring 8 limit the moving direction of the bottom end of the anchor body 1, the position of the anchor body 1 is further limited for guidance, so that the accurate drilling trajectory of the anchor body 1 and the stable drill rod operation help to ensure the installation quality of the anchor cable, improve the overall stability and safety of the anchoring project, and increase the overall practicality.
