  As shown in FIG. 4, a plurality of such cooling devices 62 are attached from the lower floor side to the upper floor side (longitudinal direction) at predetermined intervals. This mounting interval varies depending on the environmental conditions in which the escalator 10 is installed, and increases the number of cooling devices 62 to be disposed at positions that are likely to be hot.

  A temperature sensor 74 for measuring the temperature of the inner deck 54 is provided in the vicinity of the cooling device 62. One temperature sensor 74 is provided for each cooling device 62, and is provided on the lower surface of the inner deck 54.

  Next, the cooling device 76 of the outer deck 60 will be described with reference to FIGS.

  The cooling device 76 is provided on the lower surface, that is, the inner side of the outer deck 60. Like the cooling device 62 of the inner deck 54, the cooling device 76 has a plate-like cooling element (for example, a Peltier element) 78 disposed between a pair of brackets 80 and 82, and is pressed by a plate-like heat sink 84. And are fixed by bolts 86.

  As shown in FIG. 4, a plurality of cooling devices 76 are provided at predetermined intervals from the lower floor side to the upper floor side (longitudinal direction) of the outer deck 60.

  A temperature sensor 88 is provided in the vicinity of the cooling device 76 and measures the temperature of the outer deck 60. One temperature sensor 88 is provided for each cooling device 76, and is provided on the lower surface of the outer deck 60.

Further, a cooling element 78 and a temperature sensor 88 of the pair of left and right outer decks 60 and 60 are connected. Further, the cooling element 92 and the temperature sensor 102 of the pair of left and right skirt guards 44 and 44 are connected to each other.

(5) Operational state of cooling devices 62, 76, 90 Next, the operational state of the cooling devices 62, 76, 90 will be described.

  First, the temperature sensors 74, 88, and 102 of the cooling devices 62, 76, and 90 of the inner deck 54, the outer deck 60, and the skirt guard 44 measure the temperatures of the inner deck 54, the outer deck 60, and the skirt guard 44, respectively. Yes.

  Next, when the measured temperature of one temperature sensor becomes equal to or higher than a predetermined maximum temperature (for example, 50 ° C.), the control device 50 turns on the power according to the program stored in the memory of the microcomputer inside. The internal deck 54, the external deck 60, or the skirt guard 44 is cooled by starting up and operating a cooling device in the vicinity of the temperature sensor that exceeds the maximum temperature. In this case, control is performed so that each cooling device operates individually, so that a cooling device that does not exceed the maximum temperature in the shade does not operate.

  Next, when the measured temperature of one temperature sensor becomes equal to or lower than a predetermined minimum temperature (for example, 30 ° C.), the operation of the cooling device in the vicinity of the temperature sensor is stopped. In this case, each cooling device is individually stopped, and the cooling device that is exposed to direct sunlight and whose temperature is higher than the minimum temperature continues to operate.

(6) Effects According to the present embodiment, even when the escalator 10 is provided outdoors or in a place exposed to direct sunlight, and the temperature rises, the inner deck 54, the outer deck 60, and the skirt guard 44 are provided with the respective cooling devices 62. , 76, 90, the generation of thermal distortion due to thermal expansion is suppressed, and the occurrence of warpage, distortion, cracks, and the like can be prevented. Therefore, the inner deck 54, the outer deck 60, and the skirt guard 44 can be brought into contact with the steps 30 and the passengers, the passenger's clothes can be entrapped, and the intrusion of rainwater, dust and the like can be prevented, and safety can be improved.

  In addition, each cooling device 62, 76, 90 cools the high temperature portions of the inner deck 54, the outer deck 60 and the skirt guard 44 individually and operates only the necessary cooling devices, so that the cooling is performed efficiently. Can do.

  Moreover, since each cooling device 62,76,90 is provided in the inner deck 54, the outer deck 60, and the skirt guard 44, it is not necessary to change the design.

  When one cooling device fails or is newly installed, the cooling elements 64, 78, and 92 are not directly fixed inside the inner deck 54, the outer deck 60, and the skirt guard 44. , 100, it is easy to attach and detach, and can be easily attached and detached.

  In addition, the cooling elements 64, 78, and 92 are sandwiched between plate-like heat sinks 70, 84, and 98, so that heat is easily radiated.

  Further, since the temperature rise of the inner deck 54, the outer deck 60, and the skirt guard 44 can be prevented, the temperature of the balustrade 36 does not rise, the delay of the handrail belt 38 due to the increase in the running resistance of the handrail belt 38, the escalator 10 The occurrence of the stop can be prevented, and the safety and maintainability of the handrail belt 38 can be improved.

(7) Modification Example In the above embodiment, the cooling devices are provided on the inner deck 54, the outer deck 60, and the skirt guard 44, respectively, but not limited thereto, only the inner deck 54 exposed to direct sunlight, only the outer deck 60, and the skirt guard. Only 44 may be provided with a cooling device.

  Moreover, although the Peltier element was used as a cooling element in the said embodiment, you may use cooling elements other than this.

  In the above embodiment, the heat sinks 70, 84, and 98 are plate-like, but instead, the surface opposite to the cooling elements 64, 78, and 92 is provided with unevenness to further increase the heat dissipation effect. Also good.

Embodiment 2

  Next, the escalator 10 of Embodiment 2 is demonstrated based on FIG. FIG. 6 is a longitudinal sectional view of a balustrade portion according to the second embodiment.

  In the present embodiment, unlike the first embodiment, a cooling device 104 including an air conditioner is provided inside the truss 12. That is, the fixed base 108 is fixed to the frame member 106 of the truss 12 with the bolts 110, and the cooling device 104 including an air conditioner is installed on the fixed base 108. The truss 12 is provided with a temperature sensor (not shown).

  The cooling device 104 is installed near the upper floor of the truss 12, and the temperature sensor is installed on the lower floor of the truss 12. By installing in this way, the air cooled by the cooling device 104 moves downward, the temperature of the moved air can be measured, and the space with the truss 12 can be cooled uniformly.

  When the measured temperature of the temperature sensor on the lower floor side becomes higher than a predetermined maximum temperature (for example, 50 ° C.), the control device 50 operates the cooling device 104 and sets a predetermined minimum temperature (for example, 30). When the temperature is lower than (° C.), the cooling device 104 is stopped.

  Thereby, the space below the escalator 10, that is, the space with the truss 12 is cooled by the cooling device 104 from the lower floor side to the upper floor side, and the temperature of the inner deck 54, the outer deck 60, and the skirt guard 44 does not rise, Generation of thermal distortion due to thermal expansion can be suppressed, and warpage, distortion, cracks, and the like can be prevented.

  Further, since the cooling device 104 is provided on the truss 12, it is not necessary to change the design of the escalator 10.

Example of change

  In the said embodiment, although the escalator 10 demonstrated as a passenger conveyor, it may replace with this and may apply with the moving walk.
