HINGE TYPE VERTICAL FIRE DOOR CAPABLE OF OPENING A FIRE DOOR EASILY AND PUTTING OUT A FIRE AT A POWER FAILURE

摘要

PURPOSE: A hinge type vertical fire door is provided to minimize the space for installation by splitting a fire door into many units, then housing, and to put out a fire easily by opening a fire door easily using a water-pressure motor at a power failure. CONSTITUTION: The hinge type vertical fire door comprises: a support unit(10) forming a skeleton of a fire door; a housing space unit(40) projected to the upper part of the support unit(10) to house a unit fire door(20); a hydraulic pump(70) transferring hydraulic pressure through a hydraulic pipe(71); a hydraulic motor(50) transferring the rotary power by hydraulic pressure of the hydraulic pump(70) through a chain(81); a shift gear unit(80) rotating using rotary power of the hydraulic pump(70) transferred through the chain(81) and descending the unit fire door(20) along both strips of the support unit(10) to cover up the center of the support unit(10); and a water-pressure motor(60) generating rotary power if water is supplied by connecting a fire hose while the unit fire door(20) is covered, then transferring rotary power to the hydraulic pump(70), and supplying hydraulic pressure supplied from the hydraulic pump(70) to the hydraulic motor(50) in the converse direction to lift up the closed unit fire door(20), then to place in the housing space unit(40).
