[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 A pneumatic anchor drilling rig anti-tipping base includes a mounting column 1 and a fixing column 2. A base plate 3 is fixed to the bottom end of the fixing column 2. The mounting column 1 is rotatably connected inside the fixing column 2. Multiple mounting holes 4 are provided on the inner bottom wall of the mounting column 1. A locking assembly for locking the mounting column 1 is provided on the fixing column 2. The locking assembly includes a rotating shaft 5 and a spring fixing block 6. The rotating shaft 5 is fixed to the inner bottom wall of the fixing column 2. A triangular insert 7 is provided at the top end of the rotating shaft 5. The bottom end of the mounting column 1 has holes 4 that connect with the three-pronged spring fixing block 6. The angular insert 7 is fitted with a slot 8. The spring fixing block 6 is fixed on the outer wall of the fixing post 2. The spring fixing block 6 is slidably connected with an insert rod 9. The insert rod 9 passes through the spring fixing block 6 and the fixing post 2. The inner end of the insert rod 9 is rotatably connected with a ball 10. The insert rod 9 is fixed with a first spring 11. The other end of the first spring 11 is fixed to the spring fixing block 6. The outer end of the insert rod 9 is fixed with a pull ring 12. The outer wall of the mounting post 1 is provided with a locking groove 13 that is adapted to the insert rod 9.

[0024] In use, the mounting post 1 is fixed to the pneumatic anchor drilling machine by passing multiple bolts through the mounting holes 4, thus ensuring that the mounting post 1 is always connected and fixed to the pneumatic anchor drilling machine. Then, the mounting post 1, with the pneumatic anchor drilling machine fixed to it, is inserted into the fixed post 2. Simultaneously, pulling the pull ring 12 moves the insertion rod 9 outwards. At this time, the first spring 11 is stretched, and the inner end of the insertion rod 9 is pulled out of the fixed post 2. The insertion rod 9 does not restrict the downward movement of the mounting post 1 along the fixed post 2. After the mounting post 1 passes the position of the insertion rod 9, the pull ring 12 is released. Under the action of the first spring 11, the insertion rod 9 moves closer to the mounting post 1, and the ball bearing 10 on the insertion rod 9... Contact the outer wall of the mounting post 1. After the mounting post 1 moves to the bottom, rotate the mounting post 1 slightly so that the triangular insert 7 and the slot 8 can be inserted and fixed. When the mounting post 1 moves downward, the ball 10 rolls. After the mounting post 1 is connected to the rotating shaft 5, rotate the mounting post 1 so that the locking groove 13 moves to the position of the insert rod 9. The insert rod 9 continues to move towards the mounting post 1 under the action of the first spring 11 and is inserted into the locking groove 13 to fix the mounting post 1. This completes the splicing of the anti-tipping base and the pneumatic anchor drill. When disassembling, simply pull the insert rod 9 again to disengage from the locking groove 13 and lift the mounting post 1 upward to complete the disassembly.

[0025] In actual use, it was found that in order to quickly connect the triangular plug 7 to the slot 8 and quickly connect the plug rod 9 to the locking groove 13, in this embodiment, the triangular plug 7 and the locking groove 13 are provided in multiple and evenly distributed.

[0026] In actual use, it was found that the insertion rod 9 and the triangular insertion block 7 are prone to collision when they are inserted. In order to avoid the above problem, in this embodiment, the inner edge of the insertion rod 9, the edge of the locking groove 13, the edge of the triangular insertion block 7 and the edge of the slot 8 are all rounded.

[0027] In actual use, it was found that in order to enhance the structural strength, in this embodiment, multiple reinforcing brackets 14 are fixed between the fixed column 2 and the chassis 3. The reinforcing brackets 14 are fixed to the fixed column 2 and the chassis 3 by welding.

[0028] In actual use, it was found that the anti-tipping base may slip on the ground. To avoid the above problem, in this embodiment, the bottom of the chassis 3 is provided with annular anti-slip texture 15.

[0029] In actual use, it was found that in order to extend the service life, in this embodiment, the surfaces of the mounting column 1, the fixing column 2 and the chassis 3 are all provided with an anti-oxidation coating.
