Problems solved by technology

At the same time, in order to ensure the normal operation of the subway in the tunnel, the upper part of the subway tunnel is inevitably provided with a busbar that runs through the entire tunnel. The existing door body is usually hindered by the busbar and cannot normally perform airtight operations.

Embodiment 1

[0020] The protective airtight partition door of the subway section is connected with the door frame set in the subway tunnel, including the large door leaf 1, the small door leaf 2 and the small door leaf turning drive mechanism 3, the upper part of the large door leaf 1 is provided with a gap, and the small door leaf is placed in the gap The gap between the large door leaf and the door frame is sealed, the lower part of the small door leaf is hinged with the large door leaf, and the small door leaf turnover drive mechanism 3 drives the small door leaf to turn over at the top of the large door leaf.

[0021] The small door turning drive mechanism 3 includes a slide block 31, a connecting rod 32 and a chute 33 longitudinally arranged on the large door leaf and below the small door leaf. The block 31 and the small door leaf 2 are hinged, and the small door leaf 2 turns over as the slide block moves up and down. The small door turning drive mechanism 3 also includes a worm case ...

Embodiment 2

[0024] The protective airtight partition door of the subway section is connected with the door frame set in the subway tunnel, including the large door leaf 1, the small door leaf 2 and the small door leaf turning drive mechanism 3, the upper part of the large door leaf is provided with a gap, and the small door leaf is placed in the gap for sealing In the gap part between the large leaf and the door frame, the bottom of the small leaf is hinged with the large leaf, and the small door leaf turning drive mechanism 3 drives the small door leaf 2 to turn over at the top of the large leaf 1.

[0025] The small door turning drive mechanism 3 includes a pull rod 38 and a hinged rod group 37 cross-hinged in the middle of two hinged rods 371. The upper end of the hinged rod group 37 is connected to the large door leaf. Or when away from, the length of the hinged rod group increases or shortens; Flip as the length of the hinged rod set changes.

[0026] If only one hinged rod group is...

Abstract

The invention relates to the field of subway safety doors, in particular to a protective airtight partition door for a subway district. The protective airtight partition door is connected with a door frame in a subway tunnel, and comprises a large door leaf, a small door leaf and a small door leaf turning drive mechanism, wherein a notch is formed in the upper part of the large door leaf; the small leaf is arranged in the notch to seal a notch part between the large door leaf and the door frame; the lower part of the small door leaf is hinged with the large door leaf; and the small door leaf turning drive mechanism drives the small door leaf to turn at the upper part of the large door leaf. According to the protective airtight partition door for the subway district, the turnover small door leaf is arranged on the large door leaf, so that the partition door cannot be interfered by a bus-bar during the sealing operation, and the sealing partition effect in the subway tunnel is ensured; and the small door leaf turning drive mechanism adopts a more labor-saving manpower drive mechanism, and the partition door doesn't depend on electric drive and can adapt to a power failure condition likely to occur under an emergency condition.

Description

technical field [0001] The invention relates to the field of subway safety doors, in particular to a protective airtight partition door for a subway section. Background technique [0002] As a means of transportation that can carry a large number of passengers, the subway makes the subway station a place where a large number of people gather, and safety is particularly important. Therefore, all kinds of unsafe conditions that may arise, even wartime conditions, should be taken into consideration, such as the leakage of harmful gases, terrorist attacks of poisonous gases, how to effectively isolate them in a short period of time, and prevent the above-mentioned gases Spread throughout the subway tunnels, endangering more lives. At the same time, in order to ensure the normal operation of the subway in the tunnel, the upper part of the subway tunnel is inevitably provided with a busbar that runs through the entire tunnel. The existing door body is usually hindered by the busb...
