AI Technical Summary
Existing coal mine roadway grouting and water plugging equipment is structurally limited and cannot be adapted to the roadway side for sealing and limiting operations. Furthermore, the grouting is uneven and cannot meet daily usage requirements.
A device was designed that includes components such as a mobile frame, a mobile track, a grouting pump, a buffer cone, a grout outlet, a shrink frame, an airbag, and a grout delivery pipe. The device moves within the roadway via the mobile track, uses the airbag and side plates for stable positioning, and combines with the grout mixing component to achieve uniform grouting and flow guidance.
It enables stable movement of the equipment and uniform grouting within the tunnel, improving the efficiency and effectiveness of grouting and water plugging, and meeting daily usage needs.
