[0032] 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.

[0033] Please see Figures 1-7 The present invention provides the following technical solution.

[0034] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a rupture-resistant reinforced iron ore filling grouting pipe, comprising a grouting pipe body 1, a stabilizing sleeve 2, a stabilizing plate 3, and a fixing pin 4. The stabilizing sleeve 2 is fitted onto the outside of the grouting pipe body 1, and the stabilizing plate 3 is fixedly connected to both ends of the stabilizing sleeve 2. A fixing pin 4 is inserted into the side of the stabilizing plate 3 away from the grouting pipe body 1, and the lower end of the fixing pin 4 is inserted into the ground. Figure 1 and Figure 3 As shown, first, the stabilizing sleeve 2 is placed in the corresponding installation position. The stabilizing sleeve 2 drives the stabilizing plate 3 to be placed on the ground. Then, the fixing pin 4 is inserted into the ground after passing through the stabilizing plate 3 to position the stabilizing sleeve 2 and the stabilizing plate 3. Then, the grouting pipe body 1 is inserted into the middle of the stabilizing sleeve 2 and inserted into the goaf of the iron mine.

[0035] Example 2: To address the problem of poor stability and tightness in the connection between the pipe and the external sleeve in the prior art, which poses a risk of shaking, this example provides a rupture-resistant reinforced iron ore filling grouting pipe. This pipe is equipped with a protrusion 5 and a connecting mechanism 6. The stabilizing plate 3 and the stabilizing sleeve 2 are limited by the connecting mechanism 6. The connecting mechanism 6, together with the protrusion 5, enables the grouting pipe body 1 and the stabilizing sleeve 2 to form a disassembly structure. The connecting mechanism 6 consists of a connecting plate 7, a movable plate 8, a fixing rod 9, and a fixing cap 10. The structure comprises a stabilizing sleeve 2 with protrusions 5 engaged at both ends, the protrusions 5 being welded to the outer surface of the middle part of the grouting pipe body 1. A connecting plate 7 is fixedly connected to the upper end of the stabilizing plate 3, and a movable plate 8 is slidably connected to the middle of the connecting plate 7. A protrusion 5 is provided through the upper end of the movable plate 8, and a fixing rod 9 is fixedly connected to the lower end of the movable plate 8. The fixing rod 9 is engaged in the middle of the connecting plate 7, and a fixing cap 10 for locking and limiting is threaded onto the outer surface of the fixing rod 9. The fixing cap 10 is engaged in the middle of the upper end of the connecting plate 7. Figure 2 , Figure 3 and Figure 4 As shown, the grouting pipe body 1 drives the protrusion 5 to engage with the left and right ends of the stabilizing sleeve 2. Then, the movable plate 8 is pulled, and the movable plate 8 slides in the connecting plate 7. The upper end of the movable plate 8 is inserted and connected to the connecting mechanism 6. At the same time, the movable plate 8 drives the fixing rod 9 to engage with the middle of the upper end of the connecting plate 7. Then, the fixing cap 10, which is threaded to the outer surface of the fixing rod 9, is rotated, so that the fixing cap 10 moves downward and engages with the upper end of the connecting plate 7. This facilitates the limiting of the movable plate 8 and the connecting plate 7, preventing the movable plate 8 from loosening from the protrusion 5. The setting of the protrusion 5 and the connecting mechanism 6 facilitates the limiting of the stabilizing sleeve 2 and the grouting pipe body 1, thereby improving the stability of the grouting pipe body 1 during use.

[0036] Example 3: To address the problem in existing technologies where the connection between the pipe and the fixing block is a direct snap-fit ​​connection, leading to easy detachment between the fixing block and the pipe, this example provides a crack-resistant reinforced iron ore filling grouting pipe. This pipe includes a conveying pipe 11, a cover plate 12, a sealing ring 13, a fixing column 14, an auxiliary plate 15, a spring 16, an mounting block 17, and a mounting rod 18. The conveying pipe 11 is fixedly connected to the upper left end of the grouting pipe body 1, and the cover plate 12 is snap-fitted onto the upper end of the grouting pipe body 1. A sealing ring 13 is fitted between the cover plate 12 and the grouting pipe body 1. Fixing columns 14 are welded to both the left and right sides of the upper end of the grouting pipe body 1. The auxiliary plate... 15 are fixedly connected to the left and right sides of the upper end of the cover plate 12, and the far end of the auxiliary plate 15 is connected to the fixing column 14. The auxiliary plate 15, together with the mounting block 17 and the fixing column 14, drives the cover plate 12 to form a disassembly structure at the upper end of the grouting pipe body 1. A spring 16 is provided inside the auxiliary plate 15, and the movable end of the spring 16 is fixedly connected to the mounting block 17. The mounting block 17 is telescopically connected in the auxiliary plate 15, and the front and rear ends of the mounting block 17 are fixedly connected to the mounting rods 18. The mounting rods 18 and the auxiliary plate 15 form a left and right sliding structure. The mounting block 17 is inserted into the middle of the fixing column 14, and the lower side of the mounting block 17 matches the upper side of the fixing column 14. Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a conveying pipe 11 is provided at the upper left end of the grouting pipe body 1. After installation, the cover plate 12 is snapped onto the upper end of the grouting pipe body 1, and the sealing ring 13 is attached between the cover plate 12 and the grouting pipe body 1 to improve the sealing effect at the connection. At the same time as the cover plate 12 is snapped onto the cover plate 15, the auxiliary plate 15 is sleeved on the outside of the fixing column 14, and the fixing column 14 presses against the mounting block 17, causing the mounting block 17 to extend and retract within the auxiliary plate 15. The mounting block 17 causes the mounting rod 18 to move between the mounting rod 18 and the auxiliary plate 15. The sliding mechanism and the compression of the spring 16 by the mounting block 17 cause the spring 16 to undergo elastic deformation. When the cover plate 12 is fully engaged at the upper end of the grouting pipe body 1, the spring 16 undergoes elastic deformation, pushing the mounting block 17 to be inserted into the middle of the fixing column 14. This facilitates the limiting of the cover plate 12 and the conveying pipe 11, preventing the cover plate 12 from falling off at the upper end of the grouting pipe body 1. Grouting is then carried out through the conveying pipe 11. The grouting pipe body 1 is made of high-strength steel, which has high strength and prevents breakage.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
