Fireproof protective sealing door for single-leaf concrete structure of high-speed railway and subway tunnel
The invention belongs to the technical field of protective engineering, and discloses a fireproof protective sealing door for a single-leaf concrete structure of a high-speed railway and a subway tunnel. The single-leaf concrete structure comprises a door frame, hinges, door leaves, a fireproof sealing part, a linkage spring lock, a handle, a transmission mechanism, an automatic return device, a mandrel and a torsion spring, wherein the door frame is arranged in the tunnel; the hinge is positioned at one side of the door frame; the door leaves are door leaves of concrete structures, and the door laves are hinged with the door frame through the hinges; the fireproof sealing part is arranged on fitted surfaces of the door frame and the door leaves; the linkage spring lock comprises a base and locking head assemblies, and is mounted on the door leaves; the handle is mounted on the base; the transmission mechanism is separately connected to the handle and the locking head assemblies; the automatic return device comprises a base which is arranged above the hinges; the mandrel is mounted on the base; the torsion spring sleeves outside the mandrel; one end of the torsion spring is an internal connecting end, and is connected to the base; and the other end of the torsion spring is an external connecting end which is connected to the top surfaces of the door leaves. According to the scheme adopted by the invention, the fireproof protective sealing door can realize simultaneously controlling the multiple locking head assemblies to unlock or lock, improves locking effect, and improvesfirmness and reliability during locking.
本发明属于防护工程技术领域，其公开了一种高速铁路及地铁隧道单扇混凝土结构防火防护密闭门，包括门框，设置于隧道内；铰页，位于门框的一侧；门扇，为混凝土结构门扇，门扇与门框通过铰页铰接；防火密封件，设置于门框与门扇的贴合面上；联动碰锁包括基座和锁头组件，安装在门扇上，把手，安装在基座上，传动机构，分别与把手和锁头组件相连；自动复位装置包括底座，设置在铰页上方，芯轴，安装在底座上，扭转弹簧，套设在芯轴的外侧，扭转弹簧的一端为内接端，与底座相连，扭转弹簧的另一端为外接端与门扇的顶面相连。该方案能实现一个把手同时控制多个锁头组件解锁或锁闭，改善锁闭效果，提高锁闭时的牢固性和可靠性。
