Description

Technical Field

[0001] This application belongs to the technical field of mine waterproof doors, and more specifically relates to a mine roadway waterproof door device and modification method. Background Technology

[0002] To facilitate equipment maintenance in underground pump rooms, tracks are typically laid inside the pump room and connected to those in the tunnels. These tracks need to be level with the tunnel tracks. However, because waterproof doors must be installed at the safety passages of the underground pump room, and their frames are embedded in the chamber walls after installation, the pump room tracks cannot be laid at the same level as the tunnel tracks by crossing the channel steel of the waterproof door. Generally, the channel steel below the waterproof door, which obstructs track laying, is cut off before the tracks are laid to facilitate equipment and material transport. However, due to the missing channel steel below the waterproof door, the door's airtightness does not meet design requirements, posing a significant safety hazard.

[0003] Chinese invention patent CN103899221B discloses a track-mounted waterproof sealing door for underground tunnels, comprising a door panel, a door frame, a base frame, base frame rails, and an assembly, all made of metal. The door panel is rotatably mounted on the door frame, the door frame and base frame are integrated, and the assembly is mounted on the base frame and can move laterally on the base frame rails. This invention can close and lock the sealing door in the event of a water ingress accident, blocking water leakage. Furthermore, this invention has a simple structure, low cost, convenient operation, and good sealing effect.

[0004] However, this invention involves a horizontally arranged base frame rail and assembly, which requires a certain lateral distance in the tunnel. For some narrow tunnels, it is difficult to meet the installation requirements of this invention, thus having certain limitations. Summary of the Invention
