Description

Technical Field

[0001] This patent relates to the technical field of fireproof floor doors, specifically a chain-driven automatic fireproof floor door device that opens up and down. Background Art

[0002] In current logistics transmission or vertical handling scenarios, due to the limitation of the width of the shaft, there is not enough space in the left and right directions, and the shaft can only be closed by using the upper and lower space. The closed shaft door panels can only be opened and closed up and down. At the same time, in the event of a fire, in order to prevent the spread of fire due to the chimney effect, a fireproof structure must be considered for closing the shaft. There is a weight difference between the upper and lower door panels. To prevent friction and slipping during the opening of the door panels, a chain is used as the transmission medium. At the same time, the use of electromagnets as door lock triggering devices effectively improves the versatility of such doors. The current existing practice uses steel wire ropes as the transmission medium, which has the risk of slipping during operation and has no fireproof structure. The door lock is opened and opened manually or by a bow-type structure, and position matching adjustment is required for each floor;

[0003] However, there are still some shortcomings in the existing technology. For example, the steel wire rope as a transmission medium is prone to slippage, causing door opening failure. There is no fireproof structure design, which is easy to cause fire spread when a fire occurs. The door lock is opened and closed mechanically, and each door lock needs to be adjusted and matched according to the size, so the existing Utility Model Content
