Abstract

PROBLEM TO BE SOLVED: To provide a belt type moving sidewalk capable of making shallow an underfloor machine room for housing a driving device even if a large driving force is necessary, for example if a machine length is long or an inclined type having a high level difference is used. SOLUTION: Two driving devices are installed in an underfloor machine room. A sprocket wheel is provided in each of the output shafts of the two driving devices. Sprocket wheels 9 and 9' are provided in both sides of the shaft of a belt driving pulley 10. Endless motive power transmission chains are provided between the sprocket wheels provided in the output shafts and the sprocket wheels 9 and 9'. Since necessary driving forces are provided by the two driving devices, the size of each driving device is reduced and the depth of the underfloor machine room is made shallow without increasing the size thereof.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is particularly suitable for driving a belt with an inclined type having a long machine length or a large difference in height between the entrances and exits at both ends to increase the driving force for driving the belt. The present invention relates to a belt-type moving walkway that does not require a large space for accommodating a force device and can reduce the depth of an underfloor mechanical portion.

[0002]

2. Description of the Related Art In a conventional belt-type moving walkway, since the core body, which is a strength member of a belt on which a person rides, has a multi-layered canvas structure, the belt driving pulley becomes large, and the depth of the machine room at both entrances and exits is increased. However, the diameter of the driving pulley can be made smaller and the depth of the machine room can be 500 to 600 mm, or it can be made deeper by developing a new belt with a steel cord as the core. It became possible to: As a result, the weight of the device was reduced and the depth of the machine room could be made shallower, which made it easier to introduce into a building and enabled cost reduction.

[0003]

However, as described above, due to the development of the new belt, the depth of the underfloor machine room can be made shallow to bring about the above-mentioned merits. If the machine length (longitudinal length) becomes long, or the height difference becomes large in the case of an inclined moving sidewalk where the floor heights at both entrances and exits are different, the power required for the drive device to drive the belt will also increase. There is a problem of getting bigger.

FIG. 6 is a plan view showing an example of an inclined belt type moving walkway according to the prior art, FIG. 7 is a side view of FIG. 6, and FIG.
Is a sectional view taken along the line AA of FIG. 7, and FIG. 9 is an enlarged plan view of the head portion of FIG. As shown in FIGS. 6 to 9, the belt-type moving walkway includes a tread belt 6 on which a person rides, a handrail 19 and balustrades 18 provided on both sides of the belt 6 in the width direction, and the floor with a higher height is used. At one end of the belt 6 having the surface 1 is the head machine room 2 in the floor, and at the other end of the belt 6 having the lower floor surface 1 ', is the tail machine room 4 in the floor. Each is provided. In the head machine room 2, a drive pulley 10 for moving the belt 6 endlessly is provided.
A take-up pulley 15 and a tail bend pulley 16 which are follower pulleys are provided therein.

As shown in FIG. 8, a sprocket wheel 9 is provided coaxially with the drive pulley 10 on the left side of the drive pulley 10 in the head machine room 2. Further, as shown in FIGS. 6 and 9, an electric motor / speed reducer (driving device) 7 is provided on the left side in the head machine room 2. A sprocket wheel 7a having a smaller diameter than the sprocket wheel 9 is provided on the output rotary shaft of the electric motor / reduction gear 7.
Is provided. And the sprocket wheel 7a
A driving force transmission chain 8 is endlessly interposed between the sprocket wheel 9 and the sprocket wheel 9.

The belt 6 extends from the drive pulley 10 to the take-up pulley 16 and is supported by carrier rollers 12 provided on both sides in the width direction thereof. The belt 6 enters below the floor plate 5 by the tail bend pulley 16.
The take-up pulley 15 tensioned by the belt tension device 17 bends 180 °, passes through the snubb pulley 11, and is supported by the return roller 13 at the intermediate portion 3. When it enters the head machine room 2, it is wound around the snubb pulley 11 and the drive pulley 10.

As shown in FIG. 8, handrail drive sprocket wheels 20 and 20 are provided on the left and right sides of the drive pulley 10 coaxially with the drive pulley 10, respectively. An endless handrail drive chain is interposed between the sprocket wheel 20 and a handrail driven sprocket wheel (not shown) which is coaxial with the handrail drive wheel. It is designed to be driven as a drive source.

If there is only one set of the electric motor and the speed reducer 7 as the drive source as in the conventional belt-type moving walkway shown in FIGS. 6 to 9, the device inevitably becomes large and its height becomes large, and the machine is made shallow. There is a problem that the electric motor and speed reducer cannot enter the room.

Therefore, an object of the present invention is to solve the above-mentioned problems, and in a horizontal moving walkway with a long captain or an inclined moving walkway with a large height difference, even if a drive device requiring a large amount of power is required, a place can be saved. The purpose is to provide a belt-type moving walkway that can make the depth of the underfloor machine part shallow.

[0010]

[Means for solving the problem] The required power of the moving sidewalk is
In the case of the horizontal type, it changes depending on the captain, in the case of the tilted type, the height difference, and of course, the captain. In the case of a horizontal moving sidewalk, the captain is 10-40 m, 3.7 kW, 40-70 m
5.5 kW, 70-90 m 7.5 kW, 90-13
An electric motor / speed reducer of about 11 kW at 0 m and about 15 kW at 130 to 180 m is adopted.

On the other hand, in the case of an inclined moving sidewalk, the captain 2
3.7 kW at 0 m or less, 5.5 kW at 20 to 25 m, 2
7.5kW at 5-37m, 11kW at 37-48m, 4
An electric motor / speed reducer of 8 to 63 m and a power of about 15 kW is adopted (the gradient is 20%, and the horizontal length of the head and tail parts is about 7 m).

As described above, in a relatively small moving walkway, the depth of the machine room at both ends is designed to be 500 to 600 mm or less. On the other hand, a horizontal moving walkway with a long captain or an inclined moving walkway with a large height difference requires a large driving force, which increases the scale, size, and height of the electric motor / speed reducer. It may happen that you will not be able to enter.

As a result of the above, the inventor of the present invention has one drive unit (electric motor / speed reducer) too large in order to reduce the depth of the machine rooms at both ends of the belt-type moving walkway. As a result, they have found that it is sufficient to suppress the size of each drive unit and make the machine room shallow, and have reached the following invention.

According to a first aspect of the present invention, a drive pulley and a driven pulley are provided at both ends in the longitudinal direction, a belt provided by the drive pulley and the driven pulley so as to be endlessly movable, and the belt. In a belt-type moving walkway including drive means, the drive means includes two drive devices installed in a machine room provided under the floor on the drive pulley side, and output shafts of the two drive devices. A sprocket wheel provided on the drive pulley, two sprocket wheels provided on both sides of the drive pulley shaft, each of the sprocket wheels provided on the output shaft and the drive pulley provided on both sides of the drive pulley shaft. It is characterized by comprising a power transmission chain which is endlessly interposed between each of the sprocket wheels.
