Embodiment Construction

[0017] Below, refer to Figure 1 to Figure 9 The escalator 10 which concerns on one Embodiment of this invention is demonstrated.

[0018] (1) Escalator 10

[0019] refer to figure 1 The structure of the escalator 10 is demonstrated. like figure 1 As shown, a truss 12 which is a frame of the escalator 10 is supported by support angle irons 2 and 3 across the upper and lower floors of the building 1 . The support angle irons 2 and 3 placed on the building 1 are covered with mortars 4 and 5 , and the ground is finished so as to be flush with the ground of the building 1 .

[0020] like figure 1 As shown, in the machine room 14 on the upper side of the upper end of the truss 12, a driving device 18 for advancing the steps 30, a pair of left and right drive sprockets 24, 24, and a pair of left and right pulleys 27, 27 are provided. The drive unit 18 has a motor 20 , a speed reducer, an output sprocket attached to an output shaft of the speed reducer, a drive chain 22 driven ...

Abstract

The embodiment of the invention relates to a passenger conveyor. In the inspection mode, the passenger conveyor is not operated when maintenance personnel are in the machine room. The passenger conveyor is provided with: a machine room (14) provided at the end of a truss (12); a driving device 18 which is provided in the machine room 14 and moves the step 30, and a first socket 78 which is provided at the opening and which is detachably mounted with a human detection sensor 72 for detecting a person ; a second socket 86 provided in the machine room 14 and to which a human detection sensor 72 is detachably attached and a control part 50 for controlling the driving device 18. When the human detection sensor (72) is attached to the second socket (86) and a maintenance person is detected in the machine chamber (14), the control unit (50) does not operate the driving device (18).

Description

[0001] This application is based on Japanese patent application 2019-128208 (filing date: July 11, 2019) and enjoys the priority of this application. This application incorporates the entire content of this application by reference. technical field [0002] Embodiments of the present invention relate to a passenger conveyor. Background technique [0003] When maintenance personnel enter the machine room for maintenance and inspection of passenger conveyors such as escalators and moving walks, measures are taken to cut off the power supply and activate safety devices to prevent continuous operation. In addition, when there are two maintenance personnel, safety confirmation is performed by mutual signals and repetitions. [0004] However, when two maintenance personnel work on the upper and lower floors, there is a problem that due to human error, even when one maintenance personnel is in the machine room, the other maintenance personnel mistakenly starts the inspection opera...
