[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a grouting hole device for deep-hole grouting includes a guide sleeve 1. One end of the guide sleeve 1 is fixedly connected with a first end plate 2. The side wall of the guide sleeve 1 is circumferentially and equidistantly provided with placing cavities 3. The bottom of the placing cavity 3 is provided with balls 4 adapted thereto. The opening of the placing cavity 3 is internally threaded with a plug 5. One end of the plug 5 is in contact with and adapted to the ball 4. The other end of the plug 5 is provided with a one-word groove 6. The inner side of the opening of the placing cavity 3 is provided with an internal thread 7. The outer wall of the plug 5 is provided with an external thread 18. The ball 4 is movably connected between the placing cavity 3 and the plug 5.

[0024] The ball 4 is limited in the placing cavity 3 by the plug 5, and a part of the ball 4 protrudes into the guide sleeve 1. Thus, the drill pipe can be supported and guided by the ball 4. When the drill pipe is drilling, the ball 4 can roll by itself, and the contact between the ball 4 and the drill pipe is a point contact, thereby effectively reducing friction and wear and prolonging the service life of the drill pipe.

[0025] One end of the guide sleeve 1 connected with the first end plate 2 is provided with an annular groove 8. The end of the annular groove 8 is circumferentially provided with a moving cavity 9. The outside of the first end plate 2 is provided with a second end plate 10.

[0026] The second end plate 10 is penetrated by a fixed bolt 11. The second end plate 10 is circumferentially provided with round holes for the fixed bolt 11 to penetrate. The fixed bolt 11 is threadedly connected with the first end plate 2. The first end plate 2 is circumferentially provided with threaded holes for the fixed bolt 11 to be threadedly connected.

[0027] An annular part 12 adapted thereto is slidably sleeved on the annular groove 8. A pushing part 13 is slidably penetrated through the moving cavity 9.

[0028] One side of the ring 12 is fixedly connected with a connecting rod 14 around the circumference. The connecting rod 14 slides through the first end plate 2 and is fixedly connected with the second end plate 10. A circular hole for the connecting rod 14 to penetrate and slide is provided on the circumference of the first end plate 2.

[0029] On the other side of the ring 12 corresponding to the top piece 13, a wedge block 15 is fixedly connected. A wedge groove 16 corresponding to and adapted to the wedge block 15 is provided on the top piece 13. The tip of the wedge block 15 is inserted into the wedge groove 16, so that the top piece 13 is limited in the movable cavity 9, preventing the top piece 13 from detaching from the movable cavity 9.

[0030] Through the locking and fixing installation of the fixing bolt 11, the second end plate 10 can be driven to fit and approach the corresponding end plate 2. Further, the ring 12 can be pushed to slide through the connecting rod 14. Thus, the top piece 13 is pushed outwards from the movable cavity 9 through the cooperation of the wedge block 15 and the wedge groove 16, so that the top piece 13 is inserted into the inner wall of the grouting hole port on the working surface, achieving the effect of connection and fixation, and enabling the guide sleeve 1 to be fixedly installed.

[0031] The tip of the top piece 13 is provided with a slope 17.

[0032] Through the setting of the slope 17, when the guide sleeve 1 is inserted into the inner port of the grouting hole on the working surface, the inner wall of the grouting hole port can squeeze the slope 17 to make the top piece 13 contract into the movable cavity 9, preventing the top piece 13 from protruding and affecting the insertion of the guide sleeve 1 into the inner port of the grouting hole on the working surface.

[0033] The working principle of the present utility model is:

[0034] Put the ball 4 into the placement cavity 3. Rotate the plug 5 through the slotted hole 6. Screw the plug 5 into the placement cavity 3 through the cooperation of the internal thread 7 and the external thread 18, so as to limit the ball 4 in the placement cavity 3, making the ball 4 movably connected between the plug 5 and the placement cavity 3. At the same time, part of the ball 4 protrudes from the inner wall of the guide sleeve 1. When in use, insert the guide sleeve 1 corresponding to the inner port of the grouting hole on the working surface. The inner wall of the grouting hole port can squeeze the slope 17 to make the top piece 13 contract into the movable cavity 9, enabling the guide sleeve 1 to continue to be inserted. Then lock the fixing bolt 11 to make the second end plate 10 approach the first end plate 2. Further, the ring 12 can be pushed to slide through the connecting rod 14. The ring 12 slides along the annular groove 8. Thus, the top piece 13 is pushed outwards from the movable cavity 9 through the cooperation of the wedge block 15 and the wedge groove 16, so that the top piece 13 is inserted into the inner wall of the grouting hole port on the working surface, achieving the effect of connection and fixation. At this time, the drill rod can be inserted into the guide sleeve 1. At this time, the ball 4 forms support and guidance for the drill rod, and the drill rod can drill steadily.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
