Description

The present invention relates to a passenger conveyor.

The passenger conveyor may be renewed by removing the old existing passenger conveyor and installing a new passenger conveyor in the same place. In addition, the earthquake resistance of the passenger conveyor was strengthened in the wake of the recent major earthquake, and when the passenger conveyor was renewed, at least the hanging allowance between the support angle and the building beam of the building was made larger than that of the existing passenger conveyor, due to the earthquake motion. It is desired that the truss frame does not fall even when a large interlayer displacement angle is generated and the inter-beam dimension is extended relatively large.

Therefore, conventionally, as a method of extending the hanging allowance of the truss frame to the building with a simple structure, one is fixed to the truss frame side and the other is placed on the floor of the building, and the support angle and the building are hung. An additional frame that secures a hooking allowance larger than the allowance, that is, a frame provided with an extension structure is disclosed (Patent Document 1).

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing a schematic configuration of a passenger conveyor according to an embodiment of the present invention.

The existing truss frame 4 is driven by components, for example, a plurality of steps 9 that are connected endlessly and move between entrances and exits, a step drive 11 installed in the upper machine room 10, and a step drive 11. The upper sprocket 12 to be mounted, the lower sprocket 13 installed in the lower machine room 17, the step chain 14 wound around the upper sprocket 12 and the lower sprocket 13, and the railing erected on the side of the step 9 in the traveling direction. 15 and a moving handrail 16 supported by the balustrade 15 are installed.

The existing passenger conveyor 1 is erected between the lower floor 2 and the upper floor 3 of the building structure. The existing passenger conveyor 1 is formed between the lower horizontal portion 4a extending to the lower floor 2, the upper horizontal portion 4b extending to the upper floor 3, and the lower horizontal portion 4a and the upper horizontal portion 4b. It includes an existing truss frame 4 having an inclined portion 4c. At the end of the lower horizontal portion 4a, an existing lower support angle 6 mounted on the building pedestal 5 on the lower floor 2 is provided. Similarly, at the end of the upper horizontal portion 4b, an existing upper support angle 8 mounted on the building pedestal 7 on the upper floor 3 is provided.

At the tip of the existing truss frame 4 on the lower floor 2 side, a passenger conveyor floor 18 extending from between the ends of both balustrades 15 to the lower floor 2 of the building wall and the passenger conveyor floor 18 are supported at the lower part. A passenger conveyor floor frame (not shown) and a pair of extension structures 19 arranged on both sides of the passenger conveyor floor 18 and extending to the lower floor 2 in the moving direction of the passenger conveyor are configured. Similarly, a passenger conveyor floor 18 and an extension structure 19 are configured at the tip of the existing truss frame 4 on the upper floor 3 side.
Further, the intermediate portion of the extension structure 19 in the longitudinal direction is mounted on the existing lower support angle 6 or the existing upper support angle 8, and the other side of the extension structure 19B in the longitudinal direction is on the lower floor 2 or the upper floor. It is slidably placed on the floor 3.

The passenger conveyor floor 18 is received between the pair of extension structures 19 on the lower floor 2 or the upper floor 3 by taking advantage of the fact that the width W2 of the passenger conveyor floor 18 is smaller than the width W of the existing truss frame 4. A passenger conveyor floor frame for the purpose is installed. The passenger conveyor floor 18 supports the passenger conveyor floor frame by placing its open side on the passenger conveyor floor frame 21.

2, FIG. 3 and FIG. 4 are a plan view, a side view and a cross-sectional view showing the lower floor 2 side of the existing truss frame 4 at this time.

At the tip of the existing truss frame 4 on the lower floor 2 side, a passenger conveyor floor 18 extending from between the ends of both balustrades 15 to the lower floor 2 of the building wall and the passenger conveyor floor 18 are supported at the lower part. A passenger conveyor floor frame (not shown) and a pair of extension structures 19A and 19B arranged on both sides of the passenger conveyor floor 18 and extending in the moving direction of the passenger conveyor are configured. When the width of the existing truss frame 4 is W, the width of the passenger conveyor floor 18 is W2, and the width of the newly installed extension structures 19A and 19B is W3, the width W2 of the floor 18 of the passenger conveyor is the width W of the existing truss frame 4. The width W3 of the newly installed pair of extension structures 19A and 19B is substantially equal to the width W of the existing truss frame 4.

FIG. 4 shows only the configuration on the left side of the center line 20, and the configuration on the right side of the center line 20 is not shown. In the upper part of the existing truss frame 4 located near the building wall forming the lower floor 2, the width W3 of the extension structures 19A and 19B is substantially equal to the width W of the existing truss frame 4. As shown in FIGS. 3 and 4, an extension structure 19B extending to the lower floor 2 is mounted. One side of the extension structure 19B in the longitudinal direction is placed on the existing truss frame 4 and then fixed by bolts or the like. Further, the intermediate portion of the extension structure 19B in the longitudinal direction is mounted on the existing lower support angle 6, and the other side of the extension structure 19B in the longitudinal direction is slidably mounted on the lower floor 2. .. As shown in FIG. 3, the extension structure 19B is high so that when the other end in the longitudinal direction is fixed on the existing truss frame 4, one end in the longitudinal direction is placed on the lower floor 2 and is stable. The dimensions or shape in the longitudinal direction have been determined.

In particular, as shown in FIG. 4, the passenger conveyor floor frame 21 is attached to the center line 20 side of the extension structure 19B, that is, the opposite portion side of the pair of extension structures 19A and 19B. The passenger conveyor floor 18 is received by the passenger conveyor floor frame 21 by taking advantage of the fact that the width W2 of the passenger conveyor floor 18 is smaller than the width W of the existing truss frame 4. Since the passenger conveyor floor 18 is supported by placing its open side on the passenger conveyor floor frame 21, it can be opened upward in the drawing as shown by a dotted line. Up to this point, the extension structure 19B side has been described, but the extension structure 19A side is also supported and fixed in the same manner. Further, although the configuration on the lower floor 2 side of the existing truss frame 4 has been described, the same configuration is also provided on the upper floor 3 side of the existing truss frame 4.

As can be seen from the above description, in the present embodiment, the passenger conveyor floor frame 21 is fixed to the opposite portion side of the pair of extension structures 19A and 19B, and the passenger conveyor floor frame 21 receives the passenger conveyor floor 18. Therefore, the existing truss frame 4 can be diverted and the passenger conveyor can be assembled without processing the existing truss frame 4.

Further, in the present embodiment, as shown in FIG. 2, since the width W2 of the floor 18 of the passenger conveyor is smaller than the width W of the existing truss frame 4, it is easy without processing the existing truss frame 4. The above-mentioned support structure having the structure can be adopted. Further, since the passenger conveyor floor frame 21 is arranged between the facing portions of the pair of extension structures 19A and 19B, the connection with the extension structure does not become a problem.

In this way, the pair of extension structures 19A and 19B can be placed and fixed on the existing truss frame 4, and the tip ends of the extension structures 19A and 19B can be placed on the lower floor 2. It is possible to easily secure a sufficiently large hanging allowance with a simple configuration, which is larger than the hanging allowance when the existing lower support angle 6 is mounted on the building pedestal provided on the building wall in. Therefore, even when a large-scale inter-story displacement occurs, the pair of extension structures 19A and 19B can be easily maintained in the mounted state without coming off from the lower floor 2, and the seismic resistance is further improved with a simple configuration. Can be improved.

FIG. 5 is a cross-sectional view of a passenger conveyor according to another modification of the present invention.

When the width W2 of the floor 18 of the passenger conveyor is made smaller than the width W of the existing truss frame 4 as compared with the previous embodiment, a gap is formed on the sides of the extension structure 19A and the extension structure 19B. Can be considered. Therefore, a floor support 22 is provided on the opposite side of the extension structure 19A and the extension structure 19B, and the passenger conveyor floor frame 21 is fixed to the floor support 22. Further, a cover 23 is provided to cover the empty spaces on both sides while covering the upper parts of the extension structure 19A and the extension structure 19B, so that the safety of the feet of the passenger conveyor user is enhanced.

Also in this modification, since the passenger conveyor floor frame 21 is fixed to the opposite portion side of the pair of extension structures 19A and 19B and the passenger conveyor floor frame 21 receives the passenger conveyor floor 18, the existing truss frame 4 is used. It is possible to improve the earthquake resistance even when it is diverted.

FIG. 6 is a cross-sectional view of a passenger conveyor according to still another embodiment of the present invention.

In this modification, the passenger conveyor floor frame 21 is fixed to the opposite portion side of the pair of extension structures 19A and 19B, and the passenger conveyor floor 18 is received by the passenger conveyor floor frame 21. The height dimension of the extension structure 19B in the same portion is suppressed, and the upper surface flange 18A of the passenger conveyor floor 18 is placed on the upper surface thereof. The height dimension of the extension structure 19B is increased at other positions in the longitudinal direction.

According to this modification, the passenger conveyor floor frame 21 and the upper surfaces of the pair of extension structures 19A and 19B can be used to mount the upper surface flange 18A of the passenger conveyor floor 18, so that the passenger conveyor floor can be used. The above-mentioned support structure can be adopted while sufficiently securing the length 25 without suppressing the width W2 of 18 so much.

As described above, the present invention is provided with a pair of extension structures 19A and 19B fixed to the existing truss frame 4 and whose tip portions are mounted on the lower floor 2 and the upper floor 3, respectively, and a pair. A passenger conveyor floor frame 21 that receives the passenger conveyor floor 18 was fixed to the opposite portions of the extension structures 19A and 19B.

According to such a configuration, the existing truss frame 4 can be diverted and the new passenger conveyor having the pair of extension structures 19A and 19B can be assembled without processing the existing truss frame 4. Further, by adding the pair of extension structures 19A and 19B, it is possible to easily secure a sufficiently large hooking allowance with a simple configuration as compared with the conventional hanging allowance. Therefore, even when a large-scale inter-story displacement occurs, the pair of extension structures 19A and 19B can be easily maintained in the mounted state without coming off from the lower floor 2, and the structure is simple for a passenger conveyor. The earthquake resistance can be further improved.

Further, in addition to the above-described configuration, the present invention makes the width W3 of the pair of extension structures 19A and 19B substantially equal to the width W of the existing truss frame 4, and the passenger conveyor floor with respect to the width W of the existing truss frame 4. The width W2 of 18 was reduced.

According to such a configuration, the width W2 of the passenger conveyor floor 18 can be adjusted on the passenger conveyor side, so that the seismic resistance can be further improved with a simple configuration without processing the existing truss frame 4 to be diverted. Can be done.

The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described examples have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations.
