Description

Technical Field

[0001] This utility model relates to the field of ventilation engineering technology, and specifically discloses a quick-assembly earthquake-resistant duct structure for subway use. Background Technology

[0002] Subways are built underground in a closed environment, which presents problems such as high internal heat generation, poor air quality, and difficulty in smoke extraction during fires. Therefore, ventilation engineering is of great significance. Ventilation engineering is a general term for air supply, exhaust, dust removal, pneumatic conveying, and smoke prevention and exhaust systems. It is a lifeline system that ensures the safe evacuation of personnel, provides healthy air, and maintains the stable operation of equipment.

[0003] Traditional subway seismic-resistant ducts are complicated to install due to issues with installation techniques and duct design. This makes pipe connections difficult, causing misalignment of flange holes or sealing surfaces. Furthermore, some ducts lack effective emergency fixing designs and temporary fastening methods. Therefore, a quick-assembly seismic-resistant duct structure for subways is needed to solve this problem. Utility Model Content

By using a moving slip ring to push the inner retaining arc out of the docking plate, a portion of the inner retaining arc slides into the inner docking plate, at which point the positioning hole aligns with the matching hole. Bolts are then driven into both to fix the pipe. This achieves the goal of quick pipe assembly while enhancing the pipe docking accuracy, and solves the problem of difficulty in aligning flange holes or sealing surfaces during pipe installation.
