AI Technical Summary
Existing sealing pipe fixing devices have problems such as poor applicability, easy loosening, and inconvenient operation in underground coal mines. They are difficult to adapt to sealing pipes of different specifications and heights, and it is difficult to achieve precise angle adjustment, which affects the safety and stability of gas extraction.
The structure includes a receiving plate, an angle adjustment assembly, a hydraulic cylinder, and a ground insertion assembly. It fixes sealing pipes of different heights and diameters by clamping half-circles, threaded rods, and hydraulic cylinders. The angle is adjusted by using an angle hydraulic cylinder and a hemispherical head. The combination of a lifting hydraulic cylinder and a ground insertion assembly ensures the stability and flexibility of the device.
It enables stable fixing of sealing pipes of different heights and diameters, ensuring the positional stability and angle adjustment accuracy of the sealing pipes in the downhole environment, and improving the operational safety and efficiency of gas extraction.
