The drive unit 40 is provided with a step drive wheel 41 that is connected to a motor to rotate the step chain and a handrail drive wheel 42 that rotates the handrail. The motor is installed in a drive unit on either the upper floor or the lower floor. As shown in FIGS. 3 and 4, the drive unit 40 is provided with the unit bracket 50 at a position corresponding to the truss bracket 30.

FIG. 5 is a diagram showing the fixed structure 10 of the drive unit 40 of the passenger conveyor of the present invention by disassembling the circled portion A of FIG. In this embodiment, the fixed structure 10 having the same structure as the circled portion A in FIG. 1 is also adopted in the circled portions B and C in FIG.

As shown in FIG. 5, the truss bracket 30 has a substantially L-shaped angle attached to the truss frame 24, and truss side mounting holes 31 and 31 for bolting the mounting bracket 60 are formed. .. The truss side mounting holes 31 and 31 shown in the figure are two elongated holes, and have a major axis in the direction along the truss frame 24.

The truss bracket 30 has a height-direction adjuster plate 34 and a width-direction adjuster plate 37 projecting between the truss-side mounting holes 31 and 31 below the lower truss-side mounting hole 31. Adjuster holes 35 and 38 having taps formed through the adjuster plates 34 and 37 are formed through the adjuster plates 34 and 37, respectively.

As shown in FIG. 5, the unit bracket 50 has a substantially L-shaped angle attached to the unit frame 44, and is orthogonal to the surface on which the truss side mounting holes 31 and 31 of the truss bracket 30 are formed. Unit-side mounting holes 51, 51 for bolting the mounting bracket 60 are formed on the surface. The unit-side mounting holes 51 and 51 shown in the figure are two elongated holes, and in FIG. 5, the major axis is in the direction along the unit frame 44. The unit frame 44 of the circled portions B and C in FIG. 1 is a frame extending laterally.

As shown in FIG. 5, the mounting bracket 60 has a substantially L-shaped angle and has a shape in which the truss bracket 30 and the unit bracket 50 are in surface contact with each other. The mounting bracket 60 is formed with truss mounting holes 61, 61 at positions facing the truss side mounting holes 31, 31 and unit mounting holes 62, 62 at positions facing the unit side mounting holes 51, 51. .. The truss mounting holes 61 and 61 and the unit mounting holes 62 and 62 are all elongated holes, and are formed so that the truss side mounting holes 31 and 31 and the unit side mounting holes 51 and 51 intersect with each other in major axis. ..

The height-direction adjuster receiving plate 64 is formed on the mounting bracket 60 at a position facing the height-direction adjuster plate 34 with the mounting bracket 60 mounted on the truss bracket 30. In the figure, the height direction adjuster receiving plate 64 is provided on the lower side of the mounting bracket 60.

Further, the mounting bracket 60 is formed with a U-shaped recess 65 into which the width direction adjuster plate 37 can enter while the mounting bracket 60 is mounted on the truss bracket 30. The recess 65 is formed wider than the width direction adjuster plate 37 so that the width direction adjuster plate 37 can enter the recess 65 with a margin.

Then, when the drive unit 40 is removed from the truss 20, the steps shown in FIGS. 1 and 2 to 3 and 4, and when the drive unit 40 is attached to the truss 20, FIGS. 3 and 4 to 1 and The drive unit 40 is attached to and detached from the truss 20 by the process shown in FIG.

First, when mounting the drive unit 40 on the truss 20, as shown in FIG. 5, the truss bracket 30 and the mounting holes 31 and 61 of the mounting bracket 60 are aligned and temporarily tightened with bolts 32 (see also FIG. 6). do. Further, the drive unit 40 is inserted into the truss 20, the mounting bracket 60 and the mounting holes 62 and 51 of the unit bracket 50 are aligned, and temporarily tightened with the bolt 52. Since the mounting holes 31 and 61 and 62 and 51 are elongated holes, respectively, the mounting bracket 60 can be adjusted in the height direction and the width direction with respect to the truss 20, and the drive unit 40 can be adjusted with respect to the mounting bracket 60. The position can be adjusted in the height and front-back directions.

Then, as shown in FIGS. 5 and 6, adjuster bolts 36 and 39 such as jack bolts are screwed into the adjuster holes 35 and 38 of the adjuster plates 34 and 37, and the tip of the adjuster bolt 36 is applied to the adjuster receiving plate 64. By touching the tip of the adjuster bolt 39 to the mounting bracket 60, the position of the drive unit 40 is adjusted in the height direction and the width direction. In FIG. 5, the adjuster bolt 39 comes into contact with the position of the triangular mark 66 of the mounting bracket 60. When the position adjustment is completed, the bolts 32 and 52 are fully tightened. As a result, the drive unit 40 is fixed to the truss 20 via the mounting bracket 60.

As a result, the fixed structure 10 of the drive unit 40 is formed. As a result, the drive unit 40 can be fixed to the truss 20 without welding or the like. As shown in FIG. 1, the same fixing is performed at three places on one side (six places in total) in this embodiment.

The unit bracket 50 and the mounting bracket 60 are fastened by bolts 52 and frictionally supported by surface contact. Since there are errors such as distortion in the truss frame 24 and the unit frame 44, the desired bolts are fastened by long-term use. There is a risk that power cannot be expected. In such a case, as shown in FIG. 5, the mounting bracket 60 and the unit bracket 50 are formed with through holes 67 and 54 in order to prevent misalignment, and the pin 68 is inserted through the through holes 67 and 54. Is desirable (see also FIG. 6). It is preferable to use a spring pin for the pin 68 in order to prevent the pin 68 from falling out of the through holes 67 and 54. Of course, bolting may be used instead of the pin 68.

For the through holes 67, 54, for example, as shown in FIG. 5, a through hole 67 is formed in advance in the mounting bracket 60, and after fixing the drive unit 40, the through hole 54 communicating with the through hole 67 is formed in the unit bracket. By opening at 50, it can be formed in line. In FIG. 5, the positions of the through holes 54 provided in the unit bracket 50 are marked with a cross. The through holes 67 may not be formed in the mounting bracket 60 in advance, but the drive unit 40 may be fixed and then the aligned through holes 67 and 54 penetrating the mounting bracket 60 and the unit bracket 50 may be formed.

The unit bracket 50 and the mounting bracket 60 are not only frictionally supported by the fastening force of the bolt 52, but also can be displaced in the height direction and the front-rear direction by inserting the pins 68 into the aligned through holes 67 and 54. Can be suppressed.

To remove the drive unit 40 from the truss 20, the bolts 32 and / or 52 may be removed and the pin 68 may be removed. As a result, the drive unit 40 can be removed from the truss 20 without fusing or the like. When the drive unit 40 is mounted again, the truss bracket 30 can be reused, and the mounting bracket 60 can also be reused as needed.

According to the present invention, the drive unit 40 can be attached to and removed from the truss 20 by bolts and pins, and welding and fusing are not required. Therefore, even in a passenger conveyor installation location where the use of fire is restricted. Since the work can be performed on-site and even if the worker is not a qualified worker for welding / fusing, the work efficiency can be improved as much as possible.

The above description is for explaining the present invention, and should not be construed as limiting or limiting the scope of the invention described in the claims. In addition, the configuration of each part of the present invention is not limited to the above embodiment, and it goes without saying that various modifications can be made within the technical scope described in the claims.
