Embodiment Construction
[0043] Below, based on figure 1 with figure 2 Examples of the present invention will be described.
[0044] figure 1 It is a figure showing the installation state of a passenger conveyor and a rolling door, figure 2 It is a figure which shows the electric circuit of the passenger conveyor of this invention.
[0045] figure 1 Among them, the reference numerals 1 and 2 represent the floors of the 1st and 2nd floors respectively, and the reference numerals 3 and 4 respectively represent the ascending passenger conveyor and the descending passenger conveyor intersected between the 1st and 2nd floors, and , and reference numerals 5 and 8 denote opening and closing roller shutter doors for the first floor and roller doors for the second floor that are installed near the boarding and landing place of the ascending passenger conveyor 3, respectively. Reference numerals 6 and 7 denote opening and closing roller shutter doors for the first floor and roller shutter doors for the s...

The present invention relates to a passenger conveyor. The passenger conveyors such as an escalator and an automatic man-loading conveyor and the like must stop the passenger conveyor through a mode of interlocking with a rolling door; the passenger conveyor must be interlocked with the rolling door; but while the maintenance is performed and the interlocking is released, when the interlocking recovering operation is forgotten, and when the rolling door should be closed for stopping the operation of the passenger conveyor in fire disaster, a problem that the operation of the passenger conveyor can not be stopped exits. The passenger conveyor is provided with rolling door interlocking validation mechanism of the passenger conveyor. At a state that the interlocking between the passenger conveyor and the rolling door is released, even the recovering operation used for changing to the interlocking state is forgotten, when a preset condition is satisfied, the rolling door interlocking validation mechanism of the passenger conveyor automatically release the interlocking releasing state so that the passenger conveyor and the rolling door recovers to the interlocking state.
Description
technical field [0001] The present invention relates to a passenger conveyor, in particular to a technique for interlocking the opening and closing of a rolling door that blocks the passenger conveyor from the space in a building and the operation of the passenger conveyor. Background technique [0002] For passenger conveyors such as escalators and automatic people-carrying conveyor belts, when opening and closing roller shutter doors are installed within a specified distance around them, the passenger conveyor and the roller shutter doors must be able to be linked, and this linkage is necessary to prevent the spread of fire. When the rolling door is locked, the movement of the passenger conveyor is stopped in conjunction with the locking of the rolling door. [0003] However, regardless of the occurrence of a disaster such as a fire, the shutter door is usually closed after the normal operation of the passenger conveyor ends. [0004] On the other hand, during maintenance...
