Japanese Patent Laid-Open No. 06-345371

As described above, in the conventional escalator device disclosed in Patent Document 1, the scaffolding plate is provided only in the upper floor side machine room in which the drive motor is disposed, and the lower floor side machine room has a scaffolding. There is no board.
However, the machine room floor on the lower floor side is prone to oil and dust accumulation due to the positional relationship with the steps and the like, and the oil stain is remarkable. Therefore, conventionally, when performing maintenance and inspection work in the machine room on the lower floor side, it is necessary to clean the machine room floor for each work, and there is a problem that it is complicated and troublesome. If the cleaning before the start of the work is neglected, the problem is that the feet are slippery and the scaffolding is unstable, resulting in poor work efficiency, and the shoe sole of the maintenance worker becomes dirty and the shoe sole is cleaned. There is a problem that it becomes necessary, and if the shoe sole is not cleaned, the surrounding floor may be soiled, so that it takes time and work for the entire work.

  Further, in the conventional escalator device shown in Patent Document 1, since the scaffolding plate is always installed on the machine room floor, the scaffolding plate itself becomes dirty with oil, dust, etc. There are also problems such as being stable and soiling of the shoe sole, and problems that the shape of the scaffolding plate is narrow and L-shaped, the posture during work becomes unstable and workability is poor.

In addition, the machine room on the lower floor side is not equipped with equipment that instructs the operating state of the escalator, such as a control panel, so to stop the operation at the start of work and to restart the operation at the end of the work There is a problem that it is complicated and troublesome because it is necessary to go from the machine room on the lower floor side where the work is performed to the machine room on the upper floor side where the control panel is provided.
In addition, there is a problem that if the operation of the escalator is resumed unintentionally during the maintenance and inspection work, the work is disturbed.

The present invention has been made to solve such a problem, and a first object is to perform maintenance inspection work in a lower floor machine room in which a drive motor and a control panel are not provided. Without having to clean the machine room floor for each work, it is possible to secure a stable scaffold during work, work in an appropriate posture, and prevent the shoe soles of maintenance workers from getting dirty. Thus, an escalator device having good work efficiency when viewed as a whole work is obtained.
The second purpose is not to go to the machine room on the upper floor side at the start or end of the work in the machine room on the lower floor where the control panel is not arranged, and also during maintenance inspection work. Thus, an escalator device that can prevent the operation of the escalator from being resumed unintentionally is obtained.

  In the escalator device according to the present invention, machine chambers are provided at both longitudinal ends of the truss of the escalator, respectively, a drive motor that drives the operation of the escalator in one machine chamber, and a control panel that controls the operation of the escalator Is an escalator device provided with a scaffolding plate provided in the other machine room.

  According to the present invention, in the escalator device, machine rooms are provided at both longitudinal ends of the truss of the escalator, and a drive motor that drives the operation of the escalator and a control panel that controls the operation of the escalator are arranged in one machine room. The installed escalator device includes a scaffolding plate provided in the other machine room, so that maintenance and inspection work can be performed in the lower floor machine room where the drive motor and control panel are not installed. In doing so, it is possible to secure a stable scaffold during work without having to clean the machine room floor for each work, and it is possible to work in an appropriate posture and prevent the shoe soles of maintenance workers from getting dirty. It is possible to achieve the effect that the work efficiency when viewed as a whole work is good.

In the figure, reference numeral 1 denotes an escalator for transporting passengers between installed upper and lower floors. Reference numeral 2 denotes a truss that constitutes the basic framework of the escalator 1, and is constructed between the upper floor and the lower floor. An upper floor machine room 3 a is provided at the upper floor end of the truss 2, and a lower floor machine room 3 b is provided at the lower floor end of the truss 2.

A drive motor 4 that drives the operation of the escalator 1 and a control panel 5 that controls the overall operation of the escalator 1 by controlling the operation of the drive motor 4 and the like are installed in the upper floor side machine room 3a. .
An upper sprocket 6a is provided in the upper floor side machine room 3a, and a lower sprocket 6b is provided in the lower floor side machine room 3b. The upper sprocket 6a and the lower sprocket 6b are rotatably provided. An endless step chain 7 is wound around.

A plurality of steps 8 on which passengers of the escalator 1 are boarded are connected and locked to the step chain 7 in an endless manner, and the rotational drive of the drive motor 4 is transmitted to the upper sprocket 6a, so that the step chain 7 Circulates between the upper sprocket 6a and the lower sprocket 6b, whereby the step 8 circulates and moves in the truss 2.
On the truss 2, a pair of balustrades 9 are erected along the left and right sides of the step 8, and the periphery of these balustrades 9 is driven by the drive motor 4 and circulates in synchronization with the step 8. An endless moving handrail 10 is provided.

In the lower floor side machine room 3b, there is provided a scaffolding plate 11 used by workers during maintenance and inspection work of the lower sprocket 6b, the step chain 7 and the step 8 in the lower floor side machine room 3b.
The scaffold plate 11 has a substantially rectangular shape in plan view and is provided with leg portions 11a at the four corners of the lower surface. When the scaffold plate 11 is disposed on the floor surface of the lower floor side machine room 3b, these legs are provided. When the portion 11a abuts against the floor surface, a predetermined gap is formed between the lower surface of the scaffolding plate 11 and the floor surface of the lower floor side machine room 3b.

The scaffolding plate 11 is supported and connected to a wall surface of the lower floor side machine room 3b on the opposite step 8 side by a pair of left and right connecting arms 12 configured to be foldable. It is configured as follows.
That is, one end portion of the pair of first link rods 12b is rotatable by the first link pin 12d to the pair of mounting portions 12a provided on the wall surface of the lower floor side machine room 3b on the opposite step 8 side. One end of a pair of second link rods 12c is pivotally attached to the other end of the first link rod 12b by a second link pin 12e.
The other end portions of the second link rods 12c are pivotally attached to the step 8 side end portions on the left and right sides of the scaffolding plate 11 by third link pins 12f.

In this way, the scaffolding plate 11 is coupled to the wall surface of the lower floor side machine room 3b by the coupling arm 12, and normally the coupling arm 12 is folded as shown in FIG. Thus, the lower floor side machine room 3b is housed along the wall surface on the opposite step 8 side.
In a state where the scaffolding plate 11 is disposed at this storage position, the scaffolding plate 11 is sufficiently separated from the step 8 or the like, and there is no possibility that the scaffolding plate 11 interferes with the step 8 or the like.

When it is necessary to perform maintenance and inspection work for the lower floor side machine room 3b, as shown in FIG. 2, the connecting arm 12 is extended, and the scaffolding plate 11 is placed on the floor surface of the lower floor side machine room 3b. The maintenance worker rides on the scaffolding plate 11 to perform the work. Here, in the use position, the scaffolding plate 11 is disposed on the floor surface of the lower floor side machine room 3b close to the step 8 or the like that is the object of maintenance inspection.

This operation blocking switch 13 has a detection portion 13a urged by a spring or the like so as to always protrude toward the step 8 side, and the detection portion 13a is pushed into the opposite step 8 side, that is, the wall surface side. In this case, the driving prevention switch 13 does not operate, and when the pushing to the wall surface side is released and the detection portion 13a protrudes to the step 8 side by the biasing of the spring or the like, the driving prevention switch 13 operates to drive the drive motor 4 Is stopped and the operation of the escalator 1 is stopped.

In the escalator device configured as described above, the connecting arm 12 is normally folded and stored in the upright state along the wall surface of the lower floor side machine room 3b, that is, disposed in the storage position. The upper surface of the scaffold plate 11 is in contact with the detection unit 13a of the driving prevention switch 13 and has pushed the detection unit 13a toward the wall surface side. Therefore, the driving prevention switch 13 does not operate, The escalator 1 can be operated (FIG. 3).
When necessary, the connecting arm 12 is extended so that the scaffolding plate 11 is placed on the floor surface of the lower floor side machine room 3b. That is, the scaffolding plate 11 is disposed at the use position, so that the scaffolding plate 11 is placed. As a result, the detecting portion 13a of the operation blocking switch 13 that has been pushed to the wall surface side is released and protrudes toward the step 8, and the operation blocking switch 13 operates to stop the operation of the escalator 1 (FIG. 2).

In addition, although embodiment which applied this invention with respect to the escalator was demonstrated here, it cannot be overemphasized that it can apply to the general man conveyor including what is called a moving sidewalk.
In this case, although it is not possible to distinguish between the upper floor side and the lower floor side regarding the position of the machine room, it is classified into one machine room in which a drive motor and a control panel are disposed and the other machine room in which these are not disposed. One machine room corresponds to the upper floor side machine room, and the other machine room corresponds to the lower floor side machine room.

  In the escalator device configured as described above, a drive motor and a control panel are disposed in one of the machine rooms provided at both ends in the longitudinal direction of the truss of the escalator, and the other machine room. By providing a scaffolding plate, when performing maintenance and inspection work in the lower floor machine room where the drive motor and control panel are not installed, the machine room floor is not cleaned for each work and stable during work. It is possible to secure a stable scaffold and work in an appropriate posture, and it is possible to prevent the shoe soles of maintenance workers from getting dirty, and the work efficiency when viewed as a whole work is good. is there.

  Then, by providing the scaffold plate so as to be freely movable between the storage position that is normally disposed and the use position that is disposed when necessary, the scaffold plate itself is prevented from being contaminated with oil, dust, or the like. In addition, the storage position is a position in the other machine room that is separated from the step and along the wall surface, and the use position is a position that is close to the step on the floor in the other machine room. It is possible to prevent interference between the scaffolding plate and the steps when the scaffolding plate is not used.

  In addition, when the scaffolding plate is placed at the use position, it is provided with an operation stop means for stopping the operation of the escalator, so that when the work is started in the machine room on the lower floor side where the control panel is not installed. It is not necessary to go to the machine room on the upper floor at the end of the work, and at the same time, it is possible to prevent the operation of the escalator from being resumed unintentionally during the maintenance and inspection work.

  In addition, it is possible to secure a wide and stable work scaffold by making the scaffold plate substantially rectangular, and by providing this scaffold plate especially in the machine room on the lower floor of the escalator, Due to the positional relationship and the like, the working efficiency in the lower floor side machine room that is markedly soiled by oil or dust can be improved.
