[0023] The hydraulic support column guide sleeve assembly and disassembly tool, the locking block 9, locking ball 10 and fitting pad 18 used in this application are all commercially available products, and their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here. It includes a first stabilizing ring 1, with first mounting blocks 2 installed on both the front and rear surfaces of the first stabilizing ring 1, a second mounting block 3 installed on the right side surface of the first mounting block 2, and a second stabilizing ring 4 installed on the back of the second mounting block 3. A second slot 6 is provided inside the first mounting block 2, and a first slot 5 is provided inside the second mounting block 3. Locking pins 7 are provided inside the first slot 5 and the second slot 6. A connecting block 11 is installed on the right side of the second stabilizing ring 4, a stabilizing cylinder 12 is installed on the right side of the connecting block 11, and a fixing cylinder 13 is installed on the right side surface of the stabilizing cylinder 12. A threaded hole is provided inside the fixing cylinder 13, and a threaded pin 14 is provided inside the threaded hole. The threaded post 14 and the fixed cylinder 13 are mutually compatible. A rotating handle 15 is installed on the right side of the threaded post 14. A connecting rod 16 is installed at the lower end of the second stabilizing ring 4. A limiting ring 17 is installed at the lower end of the connecting rod 16. A fitting pad 18 is installed on the outer surface of the limiting ring 17. After the ring body on the outer surface of the guide sleeve is fixed by the first stabilizing ring 1 and the second stabilizing ring 4, the threaded post 14 is inserted into the threaded hole inside the fixed cylinder 13. Then, the threaded post 14 is rotated by holding the rotating handle 15 to ensure the connection stability between the threaded post 14 and the fixed cylinder 13. Then, the ring body on the surface of the guide sleeve can be disassembled and assembled by rotating the rotating handle 15. At the same time, when the first stabilizing ring 1 and the second stabilizing ring 4 are rotating, the limiting ring 17 is stably connected by the connecting rod 16. Then, the fitting pad 18 can fit against the outer surface of the guide sleeve, and the overall limiting effect of the guide sleeve is good.

[0024] Locking ring 8 is installed on the outer surface of locking post 7. The left side surface of locking ring 8 is attached to the right side surface of second mounting block 3. Locking blocks 9 are provided on the inner sidewalls of first stabilizing ring 1 and second stabilizing ring 4. Locking balls 10 are installed on the outer surface of locking block 9. First, first stabilizing ring 1 and second stabilizing ring 4 are installed on the outer surface of guide sleeve. Then, first mounting block 2 and second mounting block 3 are aligned. Then, locking post 7 is installed inside first slot 5 and second slot 6. Then, locking ring 8 is installed on the outer surface of locking post 7. Thus, the overall installation between first stabilizing ring 1 and second stabilizing ring 4 is relatively tight. At the same time, locking blocks 9 and locking balls 10 can stably abut against the ring body to be removed, ensuring stability when removing the ring body on the surface of guide sleeve. This facilitates the quick removal of the ring body on the surface of guide sleeve and has a good overall performance.

[0025] Working principle: First, the first stabilizing ring 1 and the second stabilizing ring 4 are installed onto the outer surface of the guide sleeve. Then, the first mounting block 2 and the second mounting block 3 are aligned. Next, the locking pin 7 is installed into the interior of the first slot 5 and the second slot 6. Then, the locking ring 8 is installed onto the outer surface of the locking pin 7. Thus, the overall installation of the first stabilizing ring 1 and the second stabilizing ring 4 is relatively tight. At the same time, the locking block 9 and the locking ball 10 can stably abut against the ring to be removed, ensuring stability when removing the ring from the surface of the guide sleeve, facilitating the subsequent quick removal of the ring from the surface of the guide sleeve. After the second stabilizing ring 4 abuts and fixes the ring body on the outer surface of the guide sleeve, the threaded post 14 is inserted into the threaded hole inside the fixed cylinder 13, and then the rotating handle 15 is held to rotate the threaded post 14 to ensure the connection stability between the threaded post 14 and the fixed cylinder 13. Then, the ring body on the surface of the guide sleeve can be disassembled and assembled by rotating the rotating handle 15. At the same time, when the first stabilizing ring 1 and the second stabilizing ring 4 are rotating, the limiting ring 17 is stably connected by the connecting rod 16. Then, the design of the fitting pad 18 can fit against the outer surface of the guide sleeve. The above is the working principle of this utility model.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
