Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a truss of a man conveyor that supports steps of an escalator, a pallet of a moving walkway, and the like.

[0002]

[Prior art]

 A conventional truss for an escalator is, for example, one shown in FIG. In the figure, there is a pair of pillar members 102, 103 vertically arranged on both sides of the step 101, and outer frame members 104, 105, 106, 106, 106 are provided on the upper and lower ends of the pair of pillar members 102, 103, respectively. 107 is attached. In addition, a beam member 108 is installed substantially in the middle of the pillar members 102 and 103. Rails 112 and 113 are provided on the column members 102 and 103 and the beam member 108 via support plate members 109 and 110, and rollers 114 and 115 attached to the step 101 are mounted on the rails 112 and 113. The multiple steps 101 are connected by a chain 116 via rollers 114 and 115. A horizontal lumber 117 is provided between the outer frame members 105 and 107, and an oil pan 118 is placed on the horizontal lumber 117. An exterior plate (not shown) is attached to the outside of the truss.

The multiple steps 101 are connected by a chain 116, and the chain 116 is hung between a pair of sprockets (not shown). When the sprocket is rotationally driven by a motor or the like, the chain 116 is rotated and the step 101 is moved. Oil is supplied to the chain 116 in order to smoothly orbit the chain. The oil attached to the chain 116 may drip, and the dropped oil is caught by the oil pan 118 to prevent it from leaking out of the truss.

[0004]

[Problems to be solved by the device]

 However, in such a conventional truss, the oil dripping from the chain 116 may drop to the beam member 108 as shown by the arrow, and the oil falling to the beam member 108 to the column members 102 and 103. There was a problem that the oil pan 118 was not received and was flown out of the truss without being caught by the oil pan 118, and the outer plate was contaminated.

Further, in order to increase the rigidity of the truss, a horizontal lumber 117 is required between the outer frame members 105 and 107, and the transverse lumber 117 causes the cost of the truss to increase as a whole. There were also points.

It is an object of the present invention to provide a truss for a man conveyer, which can always receive oil dripping from a chain with an oil pan and does not require horizontal timber.

[0007]

[Means for Solving the Problems]

 In order to achieve such an object, according to the present invention, a pair of pillar members arranged in a substantially vertical direction on both sides of a transfer member for mounting and transferring passengers, and a space between the pair of pillar members. A beam member and an oil pan attached between the lower ends of the pair of pillar members, and both end edges of the oil pan are protruded from the lower ends of the pair of pillar members and started up. The configuration.

[0008]

[Action]

 The oil on the chain sometimes drips as the chain goes around. This dripped oil may fall on the beam without immediately falling on the oil pan. The oil that has fallen on the beam is transmitted to the pillar material and flows, but since there is an oil pan below this that is large enough to protrude from the pillar material, it can be reliably received by this oil pan.

[0009]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. 1 and 2 are views showing an embodiment of a truss of a passenger conveyor according to the present invention.

In the figure, reference numerals 1 and 2 are a pair of pillar members which are vertically arranged on both sides of a step (transfer member) 3 of an escalator and which are made of C-shaped steel (square pipe or the like). . Outer frame members 4, 5 and 6, 7 made of square pipes are welded to the upper and lower ends of each of the pair of pillar members 1 and 2, and the C-shaped steel (other A beam member 8 made of a square pipe or the like is erected. Support plate members 9 and 10 of general structural rolled steel are attached to the beam member 8 and the column members 1 and 2 by bolts, and rails 11 and 12 are provided on the support plate members 9 and 10.

As shown in FIG. 3, on the rails 11 and 12, rollers 15 and 16 rotatably mounted on the step 3 via shafts 13 and 14 are mounted. The rails 11 and 12 move while keeping the tread portion 3a of the step 3 always horizontal and improve the riding comfort of passengers. The roller 15 is rotatably attached to each of a plurality of steps 3, and the plurality of rollers 15 are connected by a chain 17. The chain 17 is hooked between a pair of sprockets (not shown), and when one of the sprockets is rotationally driven by a motor or the like, the chain 17 orbits. Oil is supplied to the chain 17 in order to smoothly orbit it.

Between the outer frame members 5 and 7 (that is, between the lower ends of the pillar members 1 and 2), an oil pan 18 made of a steel plate and having a substantially rectangular shape as a whole is attached by welding, and the oil pan 18 is This is to prevent the oil attached to the chain 17 from dripping. Further, the oil pan 18 has a size such that both end edges 18a and 18b of the oil pan 18 protrude from the pillar members 1 and 2, and both end edges 18a and 18b of the oil pan 18 which protrude from the pillar members 1 and 2 are raised (folded upward) ) Has been.

Here, since the oil pan 18 is mounted between the outer frame members 5 and 7, the rigidity of the truss is improved, and the conventional horizontal lumber is unnecessary. An exterior plate (not shown) is attached to the outside of the truss for aesthetic reasons.

The oil attached to the chain 17 sometimes drips while the chain 17 goes around. The dropped oil may fall onto the beam 8 without immediately falling onto the oil pan 18 as shown by the arrow. The oil that has fallen on the beam 8 flows along with the pillars 1 and 2, but there is an oil pan 18 that is large enough to protrude from the pillars 1 and 2 below this. It can be received reliably.

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, the oil pan is attached between the lower ends of the pair of pillar members, and both edges are protruded from the lower end and raised, so that the oil dripping from the chain is reliably received by the oil pan. There is no such thing as soiling the exterior plate. In addition, the rigidity of the truss is improved by the oil pan, and the horizontal timber used in the past is no longer necessary, and the cost of this truss can be reduced as a whole.
