The landing plate 27 is a floor plate disposed between the comb plate 26 and the manhole cover 28, and is a flat metal plate having a rectangular shape in plan view.

  Like the landing plate 27, the manhole cover 28 is a flat metal plate having a rectangular shape in plan view, and has the same size as the landing plate 27 in the embodiment illustrated in FIG. The manhole cover 28 is a floor board that is removed when an inspection worker enters and exits the upper floor side machine room 17 during an inspection operation or the like. That is, the opening 24 closed by the manhole cover 28 is a part for entering and exiting the upper floor side machine room 17 and is generally called a manhole. The landing plate 27 may be removed together with the manhole cover 28. The landing plate 27 is different from the manhole cover 28 only in the attachment position, and has the same shape and the same attachment form as the manhole cover 28.

  On the back side of the manhole cover 28, there is a mounting unit 30 on which the manhole cover 28 is placed, a plurality of floor board supports 31 arranged on the mounting unit 30, and a detection device that detects the rising or sinking of the manhole cover 28. A detection switch device 32 is provided. The escalator 10 can quickly detect the lift of the manhole cover 28 by providing the detection switch device 32.

The placement portion 30 is a portion that protrudes from the edge of the opening 24 to the inside of the opening 24 and on which the manhole cover 28 is placed. In the form shown in FIG. 2, it is formed in a U shape in plan view along the edge of the opening 24, and has a predetermined width from the edge of the manhole cover 28, specifically, from two short sides and one long side. A region (for example, 20 to 50 mm) is supported by the placement unit 30. Moreover, as shown in FIG. 3, the mounting part 30 is provided in the position which fell below the floor surface 50 of the upper floor.
The mounting unit 30 is not particularly limited as long as the manhole cover 28 can be stably mounted and the floor board support 31 can be installed. For example, a part of the frame of the truss 14 or an L attached to the frame is used. It may be formed by a character angle or the like. Further, the structure of the placement unit 30 may be built in the upper floor.

  The floor board support 31 is a member that supports the manhole cover 28 by contacting the back side (back surface) of the manhole cover 28. Further, it has a function of adjusting the height of the floor surface that is the surface of the manhole cover 28. That is, the back of the manhole cover 28 is directly supported by the floor board support 31, and is supported by the placement unit 30 via the floor board support 31. In the form shown in FIG. 2, the floor board supports 31 are respectively arranged on the placement parts 30 positioned at the four corners of the manhole cover 28, and two floor board supports 31 that support the vicinity of the middle part of the long side of the manhole cover 28. Is arranged.

  As shown in FIG. 3, the floor board support 31 includes a bolt 33 erected on the mounting portion 30 and a contact portion 34 that is screwed into the bolt 33 and contacts the back surface of the manhole cover 28. The contact portion 34 is made of, for example, a metal core material including a bolt hole and a hard rubber covering the periphery of the core material, and the height of the floor board support 31 is adjusted by adjusting the screwing condition of the contact portion 34. And the height of the manhole cover 28 placed thereon, that is, the height of the floor surface of the upper floor side entrance / exit 16 is adjusted to the same level as the floor surface 50 of the upper floor.

  The detection switch device 32 is a contact-type detection device that detects the lifting or sinking of the manhole cover 28, and is installed on the mounting portion 30 between the floor board supports 31. In the form shown in FIG. 2, the manhole cover 28 is installed on the mounting portions 30 located in the vicinity of the four corners, more specifically, adjacent to the floor board support 31 disposed at the four corners of the manhole cover 28. The installation positions of the detection switch device 32 are preferably in the vicinity of the four corners of the manhole cover 28. From the viewpoint of cost reduction, for example, the detection switch device 32 may be set at three of the four corners or two on the diagonal line. it can.

  As shown in FIG. 4, the detection switch device 32 includes a device main body 35 connected to the control device 15 and a detection pin 36 protruding upward from the device main body 35. For example, when the manhole cover 28 is properly disposed, the detection pin 36 is pressed into the apparatus main body 35 while abutting against the back surface of the manhole cover 28. The state in which the detection pin 36 is pushed into the apparatus main body 35 can be set to an OFF state in which the switch contact is disconnected.

  Reference is now made to FIG. FIG. 5 shows a state in which the part located on the left side of the manhole cover 28 in FIG. 4 is lifted and the part located on the right side of the paper is sinked.

  As shown in FIG. 5, in the detection switch device 32 on the side where the manhole cover 28 is lifted, the detection pin 36 is not in contact with the back surface of the manhole cover 28, and extends upward. In this state, the detection switch device 32 is ON, and an ON signal is output to the control device 15. The detection switch device 32 on the side where the manhole cover 28 sinks is in a state where the detection pin 36 is further pushed into the device main body 35, that is, OFF. That is, the detection switch device 32 exemplified here is a device that detects the lifting of the manhole cover 28.

  The state where the manhole cover 28 is appropriately disposed and the detection pin 36 is pushed into the apparatus main body 35 can be turned on. In this case, the manhole cover 28 is lifted and the detection pin 36 is moved to the apparatus main body 35. The state extending upward from the position is the OFF state. Further, the protruding length of the detection pin 36 changes compared to a state in which the manhole cover 28 is appropriately disposed (that is, the detection pin 36 is pushed into the apparatus main body 35 or the detection pin 36 extends upward). In this case, the lifting and sinking of the manhole cover 28 can be detected by one detection switch device 32 as an OFF state in which the switch contact is cut off.

  The control device 15 is a device that controls the operation of the escalator 10, and has a pause unit that stops the operation of the escalator 10 when the detection switch device 32 detects the lifting of the manhole cover 28. The control device 15 is a computer that includes a CPU, an input unit used for inputting control parameters, a recording unit that stores control parameters, control programs, and the like, an input / output port, and the like. Each function can be realized by executing software, specifically, by executing a corresponding control program.

  The pause means of the control device 15 has a function of acquiring ON signals from the plurality of detection switch devices 32, and a function of stopping the operation of the escalator 10 when an ON signal is acquired from any one of the detection switch devices 32. Have Specifically, when an ON signal is acquired from the detection switch device 32, a stop command is output to the drive unit, whereby the drive unit is stopped and the driving of the step 11 and the moving handrail 12 is stopped. In addition, the suspension means can perform not only the operation suspension, but also display the operation suspension, issue a warning sound, report to the information center, and the like.

  Here, the operation of the escalator 10 having the above configuration will be exemplified.

  Here, during normal operation of the escalator 10, for example, a state in which a part of the floorboard support 31 is broken and a part of the manhole cover 28 is lifted is illustrated. When a part of the manhole cover 28 is lifted, at least one of the detection switch devices 32 respectively disposed on the mounting portions 30 located near the four corners of the manhole cover 28 detects the lift of the manhole cover 28. That is, the detection pin 36 extends upward from a normal state (a state where the manhole cover 28 is appropriately disposed), and an ON signal is output.

  The pause means of the control device 15 acquires the ON signal output from the detection switch device 32, and outputs a stop command to the drive unit. And the drive unit which received the stop command stops rotation of a motor, and the drive of step 11 and the moving handrail 12 stops. That is, the escalator 10 is in a dormant state, and at the same time, an operation stop display and a notification to the information center are performed.

  As described above, according to the escalator 10, the detection switch device 32 is provided as a detection device for detecting the lift of the manhole cover 28 that closes the opening 24 of the upper floor side machine room 17. It is possible to take an appropriate action by detecting it. In particular, when the lift of the manhole cover 28 is detected by the function of the control device 15, it is preferable to stop the operation of the escalator 10, and the safety of the escalator 10 can be further improved.

  In addition, the said embodiment can be design-changed in the range which does not impair the objective of this invention.

For example, in the above description, the detection switch device 32 is installed on the back side of the manhole cover 28, but a detection device such as the detection switch 32 may be installed on the back side of the landing plate 27.
Further, although the contact type detection switch device 32 is used as the detection device, instead of the detection switch device 32, a contactless detection switch device 32 that detects the proximity of the metal floor plate 25 and detects the floating of the floor plate 25 is detected. Proximity sensors such as capacitive sensors can also be used.

  Moreover, when the floor board 25 is directly mounted on the mounting part 30, a detection apparatus can also be installed in lower parts, such as an angle which forms the mounting part 30, for example.
