Description

Technical Field

[0001] This utility model relates to the field of railway tunnel protective door technology, and in particular to a railway tunnel protective door stop assembly. Background Technology

[0002] When trains pass through tunnels, they generate strong lateral winds on both sides, which can adversely affect personnel, structures, and equipment within the tunnel. Furthermore, with the large-scale construction of high-speed railways, the number of railway tunnels is increasing, highlighting the growing importance of fire prevention and rescue design within tunnels. Railway tunnel safety doors, as the first line of defense in evacuation routes, play a crucial role. Doorstops, installed on the doors, prevent direct collisions with walls or other obstructions, thus providing protection. Currently, existing railway tunnel safety doors lack doorstops, and commercially available doorstops are not well-suited to railway tunnel safety doors and lack height adjustment.
