Description

The present invention relates to a passenger conveyor .

  When a predetermined number of years have elapsed since the installation of the passenger conveyor such as an escalator, the respective parts constituting the passenger conveyor are renewed. The renewal method includes replacing the equipment used in the passenger conveyor with the equivalent at the time of installation, but depending on the number of years and the number of passenger conveyors requiring renewal, prepare the equivalent. Is often difficult.

  On the other hand, there is a method of exchanging each part of the passenger conveyor with the latest equipment, but for example, the structure of the truss differs depending on the age, so it may be difficult to attach the equipment currently used as it is . Thus, for example, Patent Document 1 shown below discloses a passenger conveyor drive device that can increase the degree of freedom in the installation direction and is excellent in maintenance workability.

  Further, when the driving device as disclosed in Patent Document 1 is not used, for example, renewal is performed using a method as shown in FIG. This renewal is a method performed when changing the driving device of the passenger conveyor used so far to the latest driving device. In FIG. 5, the drive device is not actually shown, but a truss in a region where the drive device is installed and a drive device receiving base for installation are shown.

  The truss 101 is an existing truss used before renewal. A driving device receiving support 102 for installing a driving device (not shown) is fixed to the truss 101, and a fixing bolt 103 protrudes upward from the driving device receiving support 102. That is, the driving device is fixed to the truss 101 by being screwed from below with the fixing bolt 103.

  However, in FIG. 5, the fixing bolt 103 is cut or scraped so as to be flush with the upper surface of the driving device support 102. This is because the fixing bolt 103 and the driving device receiving base interfere with each other when the driving device receiving base corresponding to the newly installed driving device shown in FIG. 5 is attached.

  Specifically, the flow of renewal will be described. First, an existing drive device (not shown) to be renewed is removed from the truss 101. Thereafter, the fixing bolt 103 or the like that has fixed the driving device is cut or scraped with a grinder or the like, and a new driving device receiving base support 104 for attaching and supporting the driving device receiving base to the truss 101 is attached. In FIG. 5, driving device receiving base supports 104 are attached to the four sides surrounded by the truss 101. When mounting the drive device support base support 104, for example, it is fixed by bolts or the like (of course, holes for mounting both the truss 101 and the drive device support base support 104 are processed in advance). .

After the drive device receiving base support 104 is attached, the drive device receiving base 105 is mounted on the drive device receiving base support 104 and fixed with bolts as shown in FIG. 5, and a new drive device is installed thereon. .

The power of the drive device 2 is transmitted to the drive chain sprocket 4 supported by the truss 20 via the drive chain 3. Further, the power transmitted to the drive chain sprocket 4 is transmitted to the treadle chain sprocket 5 on the same axis. Thereby, the tread 7 (only three are illustrated in FIG. 1) connected to the tread chain 6 wound around the tread chain sprocket 5 is driven.

  FIG. 2 is a perspective view showing the overall configuration of the drive device receiving base 10. The size of the drive device receiving base 10 is determined according to the installation space of the existing truss 20 (see FIG. 4) to be installed. After the drive device receiving base 10 is attached to an existing truss 20 on which a new drive device is installed, a new drive device is attached and fixed thereon. In the embodiment of the present invention, a surface on which the new driving device is attached is shown as a front surface S, and a surface that forms a front and back surface with the front surface S is shown as a back surface R for convenience.

  The drive device receiving base 10 is provided with a hole (joining hole) 2 so as to penetrate from the front surface S to the back surface R. The joint hole 11 is provided in accordance with a position where a fixing bolt 21 which is a fastening portion provided in the truss 20 can be penetrated when the drive device receiving base 10 is joined to the truss 20. Therefore, the joining holes 11 are also provided according to the number of fixing bolts 21 provided. Although the shape of the joint hole 11 is not particularly specified, the long hole increases the degree of freedom when attached to the truss 20. Therefore, it is shown as a long hole in FIG.

  In the embodiment of the present invention, the fastening portion is the fixing bolt 21. However, the fastening portion is limited to the fixing bolt as long as the driving device 2 can be fixed to the driving device receiving base 10. It will never be done.

  In addition to the joint hole 11, the drive device receiving base 10 is provided with a multipurpose hole 12 penetrating from the front surface S to the back surface R. The multipurpose hole 12 is used, for example, when an operator installs the drive device receiving base 10 in the truss 20 as a handle for holding the drive device receiving base 10 or for reducing the weight of the drive device receiving base 10. It is provided. Therefore, the drive device receiving base 10 is not essential and may not be provided, and any number of the drive device receiving base 10 may be provided as long as it does not interfere with the joint hole 11. good.

  FIG. 3 is a diagram illustrating the back surface of the drive device receiving base. A channel member 13 is provided on the back surface R of the drive device receiving base 10. The channel material 13 has a shape in which one surface of the rectangular cross section is missing, and a surface opposite to the missing surface is a driving device receiver when the driving device receiving base 10 and the driving device support 22 are joined. It will be in direct contact with the support 22. In addition, a hole 14 is provided at a position through which the fixing bolt 21 passes through to the joining hole 11 when joined to the driving device receiving base 10. In addition, this hole 14 is also a long hole in order to raise the freedom degree at the time of attachment to the truss 20 (drive device receiving support 22) similarly to the joining hole 11. FIG.

  Further, the channel material 13 is provided so as to continue from one side on the back surface R of the driving device receiving base 10 to a side facing the one side. By adopting such a shape, the strength of the drive device receiving base 10 can be maintained and improved, and the height of the fixing bolt 21 provided so as to extend upward from the existing truss 20 is absorbed. Thus, the drive device receiving base 10 can be installed at an appropriate position in the truss 20.

  In the embodiment of the present invention, as described above, the channel material 13 is continuously provided from one side on the back surface R of the driving device receiving base 10 to the side facing the one side, but is not provided continuously. In addition, for example, it may be provided only at a necessary portion. Further, the height can be arbitrarily determined.

  Next, a method of attaching the drive device receiving base 10 to the truss 20 will be described with reference to FIG. FIG. 4 shows a part of the existing truss 20 (the part where the driving device is provided), a fixing bolt 21 used to fix the conventional driving device (before replacement by renewal), and the fixing bolt. A driving device receiving support 22 having a bolt 21 and receiving the driving device is shown. Further, FIG. 4 also shows the drive device receiving base 10 so that the position when the drive device receiving base 10 is attached to the truss 20 can be understood.

  First, when replacing the old and new drive devices, the worker removes the drive device (hereinafter referred to as “old drive device”) that has been fixed to the truss 20 so far. This is done by taking the fixing bolt 21 which fixed the old drive unit. After removing the old drive device, the size of the area where the drive device 2 is installed is measured. The size measured here is an important factor for determining the size of the drive device receiving base 10 on which the newly installed drive device 2 (hereinafter referred to as “new drive device 2”) is placed.

  Note that the size of the area where the driving device is installed can be determined by referring to the design drawing, and thus does not need to be actually measured. Rather, if the size of the drive device receiving base 10 of the new drive device can be determined based on the design drawing, it becomes possible to process the drive device receiving base 10 in an appropriate size in advance at a factory or the like and install it on the site. Therefore, it is possible to improve the work efficiency and the safety of workers.

  Next, the drive device receiving base 10 is processed based on the measured size. In that case, the joining hole 11 is provided so that the fixing bolt 21 can penetrate, and the channel material 13 is joined to the back surface R thereof.

  After that, the fixing bolt 21 is passed through the hole 14 provided in the channel member 13 and the joint hole 11 of the driving device receiving base 10, and a spacer (not shown) is fastened with a nut (not shown) to tighten the driving device receiving base 10 to the truss 20. Secure to. And the new drive device 2 is installed.

  In the past, when the drive device receiving base 10 was installed on the truss 20, the fixing bolt 21 was cut or scraped so as not to interfere with the drive device receiving base 10, but the channel material 13 was joined. By doing so, the height of these existing fixing bolts 21 can be absorbed, so that it is possible to avoid cutting or the like accompanying the joining of the drive device receiving base 10. Further, since the fixing bolt 21 can be used as it is for joining the truss 20 and the drive device receiving base 10, no new parts are required for joining them. Furthermore, by adjusting the height of the channel material 13, the installation state of the new drive device 2 can be optimized in the height direction.

  Therefore, the passenger conveyor and the passenger conveyor that can be easily installed in the drive device installation space of many existing trusses with a simple configuration and can improve the working efficiency in the renewal work of the passenger conveyor and the work safety of the workers. The drive device renewal method can be provided.
