Embodiment Construction

[0019] The present invention is shown in Fig. 1, Fig. 2 and Fig. 3, comprises the driving transmission device that horizontally moves the split main door assembly and the main door leaf.

[0020] The laterally moving side-by-side main door combination consists of an upper guide rail 1, a lower guide rail 11 and left and right main door leaves 7 positioned on the guide rails 1,11. The main door leaf 7 adopts several rectangular seamless pipes as the longitudinal or crossbar 702 to bear the dead weight and load, and the door is covered with a door panel 701 of heat-insulating fireproof material, and the main door leaf 7 is welded with a hinge seat 8 which is installed to connect the connecting rod mechanism 3. Rod, the upper and lower ends of the main door leaf 7 are equipped with a number of load-bearing rollers as vertical wheels, and there are a number of lateral wheels to bear the lateral force, which is convenient for flexible opening and closing. The upper and lower ends of...

Abstract

This invention discloses one anti-fire channel door, which comprises level split sliding main door combination and main door fan drive rotation device, wherein, the device comprises one set of drive device symmetrically set on each fan two sides; each set of drive device is composed of start door and curve connection bar; the start door adopts frame structure with curve bar is of triangle rack with each point connected to main door and with other point connected to hinged linkage to connection board and main door.

Description

technical field [0001] The invention belongs to a door device, in particular to a fire prevention passage door. Background technique [0002] At present, highway tunnels, railway tunnels, municipal tunnels, and underwater tunnels generally use double-hole or multi-hole tunnels. According to the needs of disaster prevention, communication channels need to be set up at certain distances between the tunnels. Through the fire and smoke insulation of the normally closed fire doors in the passage, the fire can be divided into zones, and the passage between the double-hole tunnels can be turned into a refuge. Since the fire escape door has to withstand the impact air pressure in the tunnel during the fire, and the size of the door opening is relatively large, the requirements for the reliability and durability of the door are higher. In the prior art, there is a laterally movable side-by-side sliding door, which includes upper and lower guide rails and left and right door leaves o...
