[0021] like Figure 1-3 As shown, an auxiliary device for fast and stable advancement of anchor rod installation comprises a main rod 1, and a fixed seat 2 and a sliding seat 3 are provided at the front and rear of the main rod 1, that is, the fixed seat 2 is in two groups, and the sliding seat 3 is also in two groups. The fixed seat 2 is fixed on the main rod 1, and the sliding seat 3 is slidably arranged on the main rod 1 and locked by bolts. Multiple pairs of ear plates are fixed circumferentially on each fixed seat 2, and one end of the first connecting rod 4 is rotatably connected to the corresponding ear plate through a pin. Multiple pairs of ear plates are fixed circumferentially on each sliding seat 3, and one end of the second connecting rod 5 is rotatably connected to the corresponding ear plate through a pin. The number of the first connecting rod 4 and the second connecting rod 5 is the same and the position is corresponding. Multiple pairs of ear plates are also fixed at the front and rear ends of the corresponding branch pipes 6, and the other end of each first connecting rod 4 is hinged to the corresponding branch pipe 6, and the other end of each second connecting rod 5 is hinged to the end of the corresponding first connecting rod 4. In addition, a through hole 8 matching the drill rod 7 is provided on one side of the main rod 1, and the main rod 1 can also adopt a tube body, and a limit plate is provided in the tube body to facilitate the insertion and limit of the drill rod 7.

[0022] The branch pipes 6 are two, three, four or five. Three are preferred, because on the one hand, the weight is lighter than that of four, five or six. On the other hand, the existing anchor rod arrangement adopts a plum blossom arrangement, and the three-rod arrangement matches the existing actual situation, and three anchor rods can be pushed at the same time.

[0023] The main rod 1 is provided with a plurality of adjustment holes 10 along the circumferential direction, and the corresponding sliding seat 3 is provided with threaded holes along the radial direction, and the bolts 11 are screwed into the threaded holes and inserted into the corresponding adjustment holes 10. By providing a plurality of groups of adjustment holes 10, when the bolts 11 are screwed out, the sliding seat 3 is pushed forward and backward to adjust the spacing between the branch pipes 6, so as to match different drilled holes. After adjustment, the bolts 11 are screwed in again to tighten the limit.

[0024] The through hole 8 and the branch pipe 6 are filled with a buffer material 12. The buffer material is foam, braided fabric, soft cloth, etc., which ensures the soft connection between the anchor rod and the sleeve, the drill rod and the sleeve, reduces the hard friction loss, and can also reduce the gap between the sleeve wall and increase stability.

[0025] Working principle and process:

[0026] 1) Drill holes and inject grout in advance at the location where the anchor rod 9 needs to be installed on site. During installation, first fill an appropriate amount of buffer material into the main rod 1 and the branch pipe 6, then cut the impact head of the drill rod 7 of the hand drill and extend it into the through hole 8, and insert the anchor rod 9 to be installed into the branch pipe 6.

[0027] 2) After the device is connected, slide the two sliding seats 3, adjust the spacing between the branch pipes 6 to match the drill hole, and after the adjustment, fix the two sets of sliding seats 3 at the corresponding adjustment holes 10 by bolts. Then manually align the anchor rod 9 with the drill hole, start the hand pneumatic drill, and the device moves forward under the propulsion force of the drill rod 7.

[0028] 3) As the device moves forward, the anchor rod 9 is also pushed forward until it reaches the specified depth of the borehole. If it cannot be pushed forward, stop the hand drill in time, find out the cause and continue to push forward. The part that cannot be pushed forward is manually hit with a hammer. After the anchor rod 9 in the branch pipe 6 is installed, the buffer material is supplemented or replaced to enter the next cycle.
