Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
A fire door system with a linkage structure as shown in fig. 1 to 3 includes a carriage driving mechanism 1, a left door leaf 2, a right door leaf 3, a lower rail 4, a peripheral fire-proof device 8, and a door control assembly 5.
The bearing driving mechanism 1 provides driving force for the left door leaf and the right door leaf and consists of a motor and a transmission mechanism, wherein the motor is arranged on the bearing guide rail and drives the left door leaf and the right door leaf to move through a toothed belt.
The upper parts of the left door leaf 2 and the right door leaf 3 are connected to the bearing driving mechanism 1 through a door carrying frame, and the lower parts of the left door leaf 2 and the right door leaf 3 are provided with lower sliding chutes which are inserted into the lower guide rail 4; and local control and detection are realized.
The door control assembly 5 is integrally installed on the bearing driving mechanism 1, local control and detection are achieved, and door opening and closing of the vehicle door system are controlled.
The peripheral fire protection device 8 is installed on the vehicle body end wall, a first sealing strip 13, namely an expansion rubber strip, is arranged on the peripheral fire protection device 8, the door system is conventionally sealed with the door leaf, and the peripheral fire protection device 8 plays a role in decoration.
A second sealing strip 14 which is also an expansion rubber strip is arranged in the mounting groove at the front end of the left door leaf 2; when an accident occurs, the adhesive tape in the mounting groove of the peripheral fire-proof device 8 expands, so that the gap between the outer sliding door leaf and the vehicle body can be effectively sealed, and the fire spreading is prevented.
