Rail front protecting door system of rail traffic interval

Abstract

The invention discloses a rail front protecting door system of rail traffic interval. The rail front protecting door system of rail traffic interval comprises a door frame (3), a door body (6), a branch box (1), a travel switch connecting wire (2) and an electromagnetic lock connecting wire (7). A heavy duty hinge (4) is arranged between one side of the door body (6) and one side of the door frame (3). The door body (6) is provided with a mechanical bar pushing lock (9). An electromagnetic lock (8) is arranged between the other side of the door body (6) and the other side of the door frame (3). A travel switch (5) is arranged on the door frame (3). According to the rail front protecting door system of rail traffic interval, the door body adopts an internal and external steel plate structure with frameworks and fireproof thermal insulation cotton, a combining mode that the mechanical lock pushes a bar to trigger the electromagnetic lock is adopted, the fatigue resistance of the door body is high, the problems of door body deformation and falling-off are solved effectively, lock tools are reliable, the state of a door can be monitored in real time, and maintenance and care are convenient for operational staff.

Description

technical field [0001] The invention belongs to the technical field of rail transit section protection, and more specifically relates to a rail transit section front-track protective door system. Background technique [0002] Intersection communication passages are set up between the single-track rail transit tunnels. According to requirements, the communication passages need to be equipped with fire doors; in order to ensure the safety of the rainwater pumping room equipment, the rail transit rainwater pumping room is also equipped with fire doors. At present, the conventional fire doors of domestic rail transit interval communication channels and rainwater pump rooms are designed and manufactured according to the national standard (GB_12955). The fire doors have been deformed, fallen off or even toppled over, and serious safety accidents have occurred. [0003] In order to prevent the fire door from falling off and falling and threatening the driving safety, the subway co...
