[0002] With the popularization of automation and intelligent technology, the inspection work in places such as integrated pipeline corridors, cable tunnels and distribution cabinet rooms is increasingly undertaken by track-mounted robots.
[0003] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, it can also prevent the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.
[0004] Fire partitions will be set up on the rail logistics sections. After a fire occurs on the logistics track, the logistics carts can enter the fire partitions. However, traditional fire doors do not have the function of automatic closing and opening. They cannot automatically open and close when the logistics carts pass through the fire partitions.
