Interlock protection device and method for civil air defense door

Abstract

The invention discloses a civil air defense door interlock protection device and method, comprising: an actuator, an action assembly and a door assembly; the door assembly is installed on the civil air defense door, and the actuator is connected to the action assembly Provide power for the action assembly, and respond to the locking or unlocking command of the signal interlocking system and feed back the locking and unlocking status information of the civil air defense door to the signal interlocking system; the action assembly realizes the opening and closing of the civil air defense door In-position detection, and the locking and unlocking actions after the civil air defense door is opened in place. By adding a mechanical detection and locking device, it connects the civil air defense door with the ATP system, detects and locks the civil air defense door, and prevents accidents caused by arranging routes when the civil air defense door is unlocked.

Description

Technical field [0001] The present invention belongs to the field of locking mechanical testing mechanisms, and more particularly to a human anti-door lock protection device and method. Background technique [0002] The statement of this section is merely the background technology information related to the present disclosure, which is not necessarily constituted in prior art. [0003] The people's anti-door main safety locking device exists in the process of use, the problem that the lock is in place, for example, the main security locking device (downlock head) is restored to the working state (the lock is not extended into the lock hole), The auxiliary security device (after the door drawn rod) is exposed (disengagement) during the day and night, resulting in the end of the door-to-door door to leave the safety lock, invading the driving limit, will lead to crash accidents. [0004] In the study, the above-mentioned root cause of the accident is that the partition door safety ...

AI Technical Summary

Problems solved by technology

[0003] During the use of the main safety locking device of the civil air defense door, there is a problem that it cannot detect whether the lock head is in place. For example, the main safety locking device (lower remote lock head) returns to the working state (the lock head does not extend into the lock hole), The auxiliary safety device (door rear pull rod) of the partition door fails (disengages) when driving day and night, causing the partition door leaf to leave the safe locking end position and invade the driving limit, which will lead to a collision accident

[0004] The inventor found in the research that the root cause of the above-mentioned accidents is that the safety locking device of the partition door is defective, and it is impossible to directly visually check whether the lock head is in place. If it is not in place, it cannot be fed back to the moving train in time to avoid entering this section
