Hereinafter, the sprinkling mechanism 30 will be described with reference to FIG. The sprinkling mechanism 30 has a sprinkling section 31 and a water supply pipe 32 that supplies water to the sprinkling section 31.

The sprinkling section 31 is formed in a tubular shape having a length substantially equal to the width of the tread belt V. However, this sprinkling part 3
1 has its both ends sealed and an opening formed in the center thereof, and communicates with the tip of the water supply pipe 32 at this opening. Further, a plurality of ejection holes S are formed in the water sprinkling section 31. These jet holes S are formed at equal intervals along a line parallel to the longitudinal direction below the water sprinkling section 31. The water supplied from the water supply pipe 32 is supplied to each spout S
From the sprinkling section 31.

The watering mechanism 30 has three tape-shaped heaters T. One of the tape-shaped heaters T is spirally wound around the water supply pipe 32. The other pair of tape-shaped heaters T, T are spirally wound from the vicinity of the center to one end of the water sprinkling section 31 and from the vicinity of the center to the other end, respectively.
These tape-shaped heaters T are connected to a power supply line (not shown), and
By heating the water supply pipe 1 and the water supply pipe 32, freezing in the water sprinkling section 31 and the water supply pipe 32 is prevented. Each of the tape-shaped heaters T corresponds to a heating unit.

In the watering mechanism 30 having the above-described structure, in the pit P, the ejection holes S of the water sprinkling portion 31 face the surface of the tread belt V above the tread belt V on the upper path. , Is located. In the example shown in FIG. 1, the watering mechanism 30 is configured such that the longitudinal direction of the watering portion 31 is directed parallel to the width direction of the treadle belt V in the vicinity of the portion of the treadle belt V wound around the pulley 11. ,

The electric valve 33 is connected to a control device (not shown). On the other hand, the manual valve 34 is always open except during maintenance or the like. When the manual valve is in the open state, the control device controls the electric valve 33 to change the watering mechanism 30 to the watering state in which water is spouted from each spouting hole S of the watering portion 31 or the watering state. Can be set to a closed state in which no air is blown out. Note that the electric valve 33 and the control device correspond to a water supply control unit.

Next, the water dropping mechanism 40 will be described. As shown in FIG. 3, this waterfall treatment device 40
It has a downspout 41, a plurality of downspouts 42, an anti-freezing heater 43, and a drainage pump 44. The downspout 41 is, for example, a gutter having a U-shaped cross section and having an open upper side. The downspout belt V is provided below the right end of the treadboard belt V in FIG. V is arranged at a predetermined interval. As shown in FIG. 1, the lower end of the downspout 41 is arranged on the floor of the pit P on the entrance side.

Each gutter 42 is connected to each return roller 1.
7 are provided respectively. Each of these gutters 4
Numeral 2 is, for example, a gutter having a U-shaped cross section and having an open upper side, and is formed so that its length is slightly longer than each return roller 17. And each of these gutters 42
Are arranged directly below each return roller 17 such that the left end in FIG. 3 is higher than the right end. Each of these gutters 42 is arranged such that the right end in FIG. 3 is located directly above the downspout 41.

If water adheres to the surface (lower surface) of the tread belt V on the lower path due to surface tension, the water mainly drops on each return roller 17. The dropped water is collected in each gutter 42, guided to the gutter 42, and falls from the right end in FIG. The water that has fallen is collected by the downspout 41 and guided to the downspout 41, and discharged from the lower end of the downspout 41 onto the floor of the pit P on the entrance side.

As shown in FIG. 1, an antifreezing heater 43 is arranged on the floor of the pit P on the entrance side. The anti-freezing heater 43 corresponds to an anti-freezing section. The anti-freezing heater 43 is connected to a power supply line (not shown) and heats water on the floor of the pit P. Therefore, the floor of the pit P does not freeze. A drain pump 44 may be provided below the floor of the pit P. The drain pump 44 prevents the accumulation of a large amount of water on the floor of the pit P by discharging the water collected on the floor of the pit P to a drain passage (not shown). Similarly, the pit P on the exit side shown in FIG.
May be provided on the floor of the pit P, and a drainage pump 44 may be provided below the floor of the pit P.

Hereinafter, the operation of this embodiment will be described. In addition, each tape-shaped heater T and the freeze prevention heater 43
Is always energized. On the other hand, the watering mechanism 30 is in a watering state only when the moving sidewalk device is operated.

In FIG. 2, when the pulley 14 is driven by a motor (not shown) and rotates counterclockwise in FIG. 2, the tread belt V moves from the pulley 11 to the pulley 14 in the upper path. At the same time, on the lower side of the path, on the other hand, it moves from the pulley 14 to the pulley 11 side. The pulleys 11 and 12 are driven by the tread belt V to rotate in the counterclockwise direction in FIG. On the other hand, the pulleys 13 and 15 are driven by the tread belt V and rotate clockwise in FIGS. 1 and 2, respectively.

In the state in which the tread belt V is moving, the water sprinkling mechanism 30 spouts water from the spout holes S of the sprinkling portion 31 to the surface of the tread belt V. For this reason, the surface of the tread belt V is in a wet state over its entire width. The tread belt V whose surface is wet in this way moves and exposes its surface to the outside after the position of the comb C on the entrance side.

In this state, the user proceeds from the slope surface G to the floor plate F at the entrance side shown in FIG. Since the user walks on the snow-covered slope surface G to the entrance of the moving sidewalk device, snow will inevitably adhere to the surface of the tread belt V.
However, since the surface of the tread belt V is wet over the entire area, the attached snow is immediately melted. For this reason, the surface of the tread belt V maintains a state in which it is not slippery.

Since the tread belt V moves from the entrance side to the exit side, the user can climb up the slope of the slope while riding on the tread belt V. Then, the user approaches the comb C on the exit side shown in FIG. 2 and transfers to the comb plate 20 across the comb C. Further, the user can use the floor plate F
Proceed to the slope surface G through.

After the pulley 14 on the exit side, the tread belt V proceeds on the lower path. That is, the tread belt V whose surface has been turned up to now has its surface turned down after the pulley 14. Therefore, most of the water on the surface of the tread belt V is
In the vicinity, it falls onto the floor of the pit P. The water that has fallen on the floor of the pit P is not frozen by being heated by the freeze prevention heater 43. The water on the floor of the pit P is discharged to the outside of the pit P by the drain pump 44.

As described above, the tread belt V drops most of the surface water on the exit side, but some of the water
It still adheres to the tread belt surface due to surface tension. The tread belt V moves toward the entrance with the water adhered as described above. When the tread belt V reaches the return rollers 17, the step belts V wet the return rollers 17. For this reason, water drops from each return roller 17.

The water dropped from each return roller 17 is collected by each gutter 42, guided by the gutter 42, and falls to the downspout 41. The water that falls is the downspout 41
And is discharged from the lower end of the downspout 41 onto the floor of the pit P on the entrance side. The water discharged onto the floor of the pit P is not frozen by being heated by the anti-freezing heater 43. Then, the water on the floor surface of the pit P is discharged out of the pit P by the drainage pump 44.

As described above, when the moving sidewalk apparatus is operated, the surface of the tread belt V is always wet, so that the snow falling on the tread belt V immediately melts. Is done. Therefore, the user can safely use the moving sidewalk device without slipping on the tread belt V.

The water dripping from each of the return rollers 17 is completely removed from each of the downspouts 42 and downspouts 4 of the water dropping mechanism 40.
1 leads to the pit P on the entrance side. Then, the water in the pit P is drained by a drain pump 44 provided below the floor of the pit P. For this reason, even if a drainage pump or the like is not separately provided under each return roller 17, the water falling treatment mechanism 40 can discharge the dropped water to the outside of the moving sidewalk device without freezing.
Therefore, the moving sidewalk device always operates normally without any trouble caused by freezing.

[0048]

According to the moving sidewalk device of the present invention constructed as described above, the surface of the tread belt is wet, so that the snow and the like adhering to the surface are immediately melted. For this reason, the surface of the tread belt V always keeps the slip-resistant state. Therefore, the user can safely use the moving sidewalk device.

Further, if the moving sidewalk device is provided with a waterfall treatment mechanism, all water adhering to the tread belt surface is collected under the floor plate and treated without freezing. Therefore, the moving sidewalk device can always operate normally.
