Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an exterior plate mounting structure in which an exterior plate is attached to a truss of a passenger conveyor.

[0002]

[Prior art]

 As a structure in which an exterior plate is attached to a truss of a conventional escalator, there is a structure as shown in FIG. 2, for example. In the figure, the truss 101 has a pair of pillar members 103 and 104 vertically arranged on both sides of the step 102, and an outer frame member 105 is provided at the upper and lower ends of each of the pair of pillar members 103 and 104. , 106 and 107, 108 are attached. Further, a beam member 110 is installed substantially in the middle of the pillar members 103 and 104, and an oil pan 109 is provided between the outer frame members 106 and 108.

The outside of the truss 101 is covered with an exterior plate 113. The exterior plate 113 is composed of side plates 114 and 115 located on the side surfaces of the truss 101 and a bottom plate 116 located on the bottom surface. . The reinforcing portions 114a and 115a of the side plates 114 and 115 are welded with substantially L-shaped cross-section supporting pieces 117 and 118, and the supporting pieces 117 and 118 are welded to the outer frame members 106 and 108. In this way, the side plates 114 and 115 are attached to the outer frame members 106 and 108, and then the bottom plate 116 is attached to the lower ends thereof.

[0004]

[Problems to be solved by the device]

 In such a conventional exterior plate mounting structure, the welding work performed when covering the truss 101 with the exterior plate 113 is performed from the inside of the truss 101. By the way, the step 102 and the like are located inside the tras 101. Therefore, the welding work performed inside the truss 101 is difficult and time-consuming.

An object of the present invention is to provide an exterior plate mounting structure for a passenger conveyor, which allows the work of covering the truss with the exterior plate to be performed from the outside of the truss.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, in the present invention, a truss of a man conveyor, an exterior plate for covering the outside of the truss, and one of the exterior plate and the truss are provided. By providing an engaging portion and an engaged portion provided on the other of the exterior plate or the truss and engaging with the engaging portion, the engaging portion is engaged with the engaged portion. The exterior plate is attached to the truss.

[0007]

[Action]

 The engaging portion (or the engaged portion) provided on the exterior plate is engaged with the engaged portion (or the engaging portion) of the truss to attach the exterior plate to the truss. Since the mounting work at this time is a work for engaging the engaging portion and the engaged portion, this work can be performed from the outside of the truss.

[0008]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a view showing an embodiment of an exterior plate mounting structure for a passenger conveyor according to the present invention.

In FIG. 1, the truss 1 has a pair of pillar members 3 and 4 made of C-shaped steel and arranged vertically on both sides of the step 2 of the escalator. Outer frame members 5, 6 and 7, 8 made of square pipes are welded to the upper and lower ends of each of the pair of pillar members 3, 4, and the pillar members 3, 4 are made of C-shaped steel at an approximately intermediate position therebetween. Beam members 9 are erected. Support plate members 10 and 11 of rolled steel for general structure are attached to the beam member 9 and the pillar members 3 and 4 by bolts, and rails 12, 13 and 14, 15 are provided on the support plates 10 and 11, respectively. There is.

On the rails 12, 13 and 14, 15 are mounted rollers 16, 17 and 18, 19 rotatably attached to the step 2 via a shaft. The rails 12, 13 and 14, 15 move the tread portion 2a of the step 2 while always keeping the tread portion 2a horizontal, and improve the riding comfort of passengers. The rollers 16 and 18 are rotatably attached to a plurality of steps 2, and the plurality of rollers 16 and 18 are connected by chains 19 and 20. The chains 19 and 20 are hung between a pair of sprockets (not shown). When one of the sprockets is rotationally driven by a motor or the like, the chains 19 and 20 orbit. The chains 19 and 20 are supplied with oil in order to smoothly orbit them.

Between the outer frame members 6 and 8, an oil pan 21 made of a steel plate and having a substantially rectangular whole shape is attached by welding. The oil pan 21 contains the oil attached to the chains 19 and 20. It catches the droop. Further, the oil pan 21 has such a size that both end edges 21a and 21b thereof protrude from the pillar members 3 and 4, and both end edges 21a and 21b protruding from the pillar members 3 and 4 are raised (folded upward). Has been.

The outside of the truss 1 is covered with an exterior plate 22, and the exterior plate 22 is composed of side plates 23 and 24 located on the side surfaces of the trusses 3 and 4, and a bottom plate 25 located on the bottom surface. . The side plates 23 and 24 are plate-shaped with a substantially rectangular shape as a whole, and their lower ends 23a and 24a are bent inward. Reinforcing portions 23b and 24b are provided on the back surfaces of the side plates 23 and 24, and the base end sides 26a and 27a of the engaging portions 26 and 27 formed in steps are provided below the reinforcing portions 23b and 24b. Are welded to each other, and a gap having a thickness of both ends 21a and 21b of the oil pan 2 is formed between the tip ends 26b and 27b and the side plates 23 and 24. The engaging portions 26 and 27 are attached to the back surfaces of the side plates 23 and 24 over the entire width.

On the other hand, both end edges 21a and 21b of the raised oil pan 21 can be relatively inserted between the tip ends 26b and 27b of the engaging portions 26 and 27 and the side plates 23 and 24. . Here, both end edges 21a and 21b are engaged parts that engage with the engaging parts 26 and 27. Since the oil pan 21 is attached over the entire bottom surface side of the truss 1, the engaged portions 21a and 21b also extend over the entire bottom surface side.

The engaging portions 26, 27 attached to the side plates 23, 24 are engaged with the engaged portions 21 a, 21 b of the oil pan 21 to attach the side plates 23, 24 to the truss 1. Since the mounting work at this time is a work of relatively inserting the engaged parts 21a and 21b between the engaging parts 26 and 27 and the side plates 23 and 24, this work should be performed from the outside of the truss 1. You can When the side plates 23 and 24 are attached to the truss 1, the bottom plates 25 are fixed to the truss 1 by screws while applying the bottom plates 25 to the lower ends 23a and 24a bent inside the side plates 23 and 24, respectively.

It goes without saying that the present invention is applicable not only to escalators but also to moving walkways.

[0016]

[Effect of device]

 As described above, according to the present invention, since the exterior plate is attached to the truss by engaging the engaging portion with the engaged portion, this attaching work can be performed from the outside of the truss. it can. Therefore, the mounting work is simple and can be performed quickly.
