Description

Passenger Conveyor

technical field

The invention relates to a passenger conveying device for an escalator, an electric passage, etc., in particular to a passenger conveying device suitable for being arranged in a narrow place.

Background technique

In order to reduce the width dimension of the passenger conveyor, a conventional method that has been disclosed is to adopt a structure in which a motor is arranged around a drive shaft driving a step to directly drive the drive shaft (for example, Japanese Patent Laid-Open No. Sho 56-108683 ), or It adopts a structure in which a step driving chain is directly driven between the going channels of the steps (for example, Japanese Patent Application Laid-Open No. 55-40185).

In addition, for example, Japanese Patent Application Laid-Open No. 2001-139273 discloses a technology in which the distance between the left and right railings is set to be greater than that of the left and right moving handrails in order to avoid collisions between passengers' carry-on luggage and the railings. Wide spacing to visually widen the width of the passenger conveyor.

In the above-mentioned prior art, the advantage of the former is that the step and the step chain are directly driven by the motor to omit redundant drive chains and drive sprockets for power transmission, thereby reducing the width accordingly.

In addition, in the latter of the above-mentioned prior art, since the possibility of the passenger's carry-on luggage colliding with the railing railing is reduced, the passenger can take the passenger conveyer more leisurely.

However, the former of the above-mentioned prior arts does not take into account the situation when the width dimension needs to be further reduced, so it is actually difficult to further reduce the dimension in the width direction.

Moreover, in the latter of the above-mentioned prior art, at the entrance and exit portion of the passenger conveyor, since the interval of the moving handrail is narrower than that of the railings that have been widened, the interval difference will correspondingly form a drastic ups and downs. Therefore, there is a problem that the back of the guide member that guides the moving armrest will collide with the carry-on luggage, causing the passenger to fall.

Contents of the invention

An object of the present invention is to provide a passenger conveyor that can sufficiently reduce its width dimension.

Another object of the present invention is to provide a passenger conveying device that allows passengers to ride comfortably even after the width of the passenger conveying device is reduced, and when getting off, carry luggage, etc. will not interfere with the guide member that guides the moving handrail. side-to-side collision.

In order to achieve the above object, in the present invention, the tooth portion of the drive sprocket coaxial with the drive sprocket and the left and right side frames constituting the main frame are arranged so that their vertical projections overlap each other, wherein the drive sprocket is wound on the drive sprocket. A rung chain that connects multiple rungs.

Moreover, the interval between the inner surfaces facing the railings vertically arranged on both sides of the step moving direction is set to be wider than the interval of the moving handrails, and at the terminal part of the length direction of the railings, the interval between the widened inner surfaces is set gradually. Approach the spacing of the moving handrails.

That is, by arranging the tooth portion of the drive sprocket and the side frame of the main frame so that the mutual vertical projections overlap, the gap that originally exists between the tooth portion of the drive sprocket and the side frame can be canceled, so that the corresponding The side frame is arranged closer to the drive sprocket side, and as a result, the width dimension of the main frame can be reduced.

In addition, by setting the interval between the inner surfaces of the left and right railings wider than the interval between the moving handrails, passengers' hand luggage, etc. will not come into contact with the railings, so passengers can ride the passenger conveyor with ease. At the terminal part of the direction, the widened inner surface interval is set to gradually approach the interval of the moving handrail, so that when passengers get off, their hand luggage and the like will not collide with the back side of the guide member that guides the moving handrail.

In general, the escalator 1 is constructed on the basis of a main frame 4 installed across the upper floor 2 and the lower floor 3 of a building. As shown in FIG. 3 , the main frame 4 is composed of a pair of left and right side frames 5A, 5B and a bottom plate 6 connecting the left and right side frames 5A, 5B, beams 7, etc., and the side frames 5A, 5B are formed along the automatic The escalator is composed of an upper string 8A and a lower string 8B extending in the longitudinal direction, and a vertical member 9 connecting the upper string 8A and the lower string 8B.

The upper horizontal part 10 used as the upper machine room is formed on the upper layer 2 side of the main frame 4 adopting the above structure, and the lower horizontal part 11 used as the lower machine room is formed on the lower layer 3 side, and the upper horizontal part 10 and the lower horizontal part 11 is connected with an inclined portion 12 . In general, the upper portion of the upper horizontal portion 10 and the upper portion of the lower horizontal portion 11 are covered by entrance and exit floors 10F, 11F for passengers to enter and exit, respectively.

A pair of driving sprockets 13 and driven sprockets 14 are pivotally supported below the entrance and exit floors 10F, 11F of the upper horizontal portion 10 and the lower horizontal portion 11 of the main frame 4 thus constituted. A pair of drive sprockets 13 are fixed to a drive shaft 15 , both ends of which are rotatably supported by bearings 16 . This bearing 16 is fixed on the longitudinal part 9 of said side frame 5A, 5B, projected vertically within the width h of the side frame 5A, 5B.

An endless step chain 17 is wound around the driving sprocket 13 and the driven sprocket 14 , and the step chain 17 is connected to a step 18 . The steps 18 have front wheels 19A and rear wheels 19B running on guide rails provided in the main frame 4 . Furthermore, the front wheel 19A is rotatably supported by a front wheel shaft protruding in the width direction of the steps 18 , and by connecting the front wheel shaft to the step chain 17 , a plurality of steps 18 are connected to the step chain 17 .

In addition, rails 20 are vertically provided in the side frames 5A, 5B, respectively, and moving handrails 21 are guided by the peripheral edges of the rails 20 . The railing 20 has a pillar 22 vertically arranged in the upper string material 8A of the side frames 5A, 5B, and the armrest frame 23 supported by the upper end of the pillar 22 is arranged in the armrest frame 23, and the upper end is supported by the upper end of the pillar 22. The upper end is supported and the lower end is supported by the lower end part of the pillar 22, the railing balustrade 24 on the side of the step 18 of the pillar 22, the inner cover plate 26 covering the lower part of the railing balustrade 24, the inner cover plate 26 and the inner cover plate 26 The protective skirt 27 separated from the steps 18, and the outer cover 25 arranged on the outer side of the armrest frame 23.

In addition, as shown in Fig. 1 and Fig. 3 etc., for example, in the case where the escalator 1 is installed close to the wall W of the building, and the opposite side of the wall W is provided with the stairs S, the outer layer decorative plate 28 for decoration is removed from the wall W of the building. The outer cover plate 25 is vertically arranged on the outside of the railing 20 on the side of the stairs S, while the railing 20 on the wall W side can be set by placing the handrail frame 23 close to the wall W and covering the gap between them with the outer cover plate 25 , so that the construction of the outer decorative panel 28 can be omitted.

The railing balustrade 24 of the railing 20 thus constituted has a peripheral portion 29 whose end portion is adjacent to the inner face of the handrail frame 23, a base portion 30 whose end portion is adjacent to the inner face of the inner cover plate 26, and the peripheral portion 29 and the base portion Compared with the portion 30, the inner surface portion 31 located farther on the opposite side of the step and whose height H accounts for more than half of the vertical height, and the inner surface portion 31 and the peripheral edge portion 29 and between the inner surface portion 31 and the base portion 30 Between the inclined portions 32A, 32B formed at an angle θ1 larger than 90 degrees with respect to the inner surface portion 31 , the inner surface portion 31 , the peripheral edge portion 29 and the base portion 30 form a recess opening toward the side of the step 18 as a whole. A recess having an inner surface portion 31 of height H is formed substantially over the entire length of the railing 20, as shown by arrows B, C in FIG. The end portion in the longitudinal direction is connected to the peripheral edge portion 29 via an inclined portion 32A. Also, the recess is configured to have a width Wa that increases the width of the portion of the recess above the passenger's feet from the center A of the moving armrest 21 toward one side. Furthermore, the concave portion is a linear concave portion formed by the peripheral portion 29, the base portion 30, and the inner surface portion 31, but may be formed as a curved surface as a whole as shown by the two-dashed line D in FIG. 5 .

The inclined portion 32A between the peripheral portion 29 and the inner surface portion 31 of the railing balustrade 24 preferably has an inclined angle such that the inclined extension line does not intersect with the handrail frame 23 . In addition, the inclined portion 32B between the base portion 30 and the inner surface portion 31 has an inclined angle such that an inclined extension line does not intersect with the inner cover plate 26 . Furthermore, by setting the inclination angle θ2 ( FIG. 6 ) of the inclined portion 32A at the terminal portion in the longitudinal direction of the railing 20 to be larger than the angle θ1, it is possible to adjust 1. Passenger's carry-on luggage getting off the passenger conveyor is smoothly guided as indicated by arrow E. At this time, it is also possible not to adopt the structure that the inclined extension line of the inclined portion 32A does not intersect with the armrest frame 23, but as long as there is no large height difference between the inclined portion 32A and the armrest frame 23, even if the inclined extension line of the inclined portion 32A and the armrest frame 23 There is no problem with intersecting either.

In addition, as shown in FIG. 6 , an operation switch 50 such as a start switch and a stop switch of the escalator 1 is provided in the inclined portion 32A of the terminal inclined surface that becomes the terminal portion in the longitudinal direction of the balustrade 24. A switch box 51 is attached to the back side. In this way, by arranging the operation switch 50 on the terminal inclined surface of the terminal part of the length direction of the railing balustrade 24, since the operation position is higher than its original position, the operation switch can be made more eye-catching and more convenient to operate. , thereby having the effect of improving the operational performance.

Wherein, the inner surface portion 31 is the surface of the railing in the first invention away from the moving handrail, and the inclined portion 32A is the surface close to the moving handrail. And, the concave portion provided at the railing of the portion surrounded by the moving handrail according to the second invention is a concave portion formed by the inner surface portion 31 , the peripheral portion 29 and the base portion 30 . In addition, the interval of the railing balustrade described in the third invention refers to the interval between the left and right railing balustrades 24, the interval of the widened railing balustrade refers to the interval W1 between the left and right inner surface parts 31, and the interval of the moving handrail It refers to the interval W2 between the left and right moving handrails 21 .

On the other hand, the driving shaft 15 for fixing the pair of driving sprockets 13 fixes the driving sprockets 33 on the side opposite to the step in the driving sprockets 13 on one side. The drive sprocket 33 is formed in a disc shape that becomes larger toward the bearing 16 side, and the tooth portion formed on the outer periphery is provided within the width h of the side frame 5A of the main frame 4 . The toothing overlaps the side frame 5A, that is to say the toothing of the drive sprocket 33 overlaps the mutual perpendicular projection of the side frame 5A. For this purpose, the mutual vertical projections of the toothing of the drive sprocket 33 and the bearing 16 and the side frame 5A of the main frame 4 also overlap and lie within the width h of the side frame 5A.

A power transmission chain 34 is wound around the teeth of the drive sprocket 33, and the power transmission chain 34 is wound on a sprocket 36 of a drive mechanism 35, wherein the sprocket 36 of the drive mechanism 35 is set In the upper horizontal portion 10 of the main frame 4 outside the to-and-fro passage of the steps 18 . The driving mechanism 35 is composed of a motor 37 , a speed reducer 38 , a brake 39 , and the like, but the speed reducer 39 is not indispensable.

In addition, handrail driving sprockets 40 are respectively fixed on opposite sides of the steps of the pair of driving sprockets 13 , and handrail driving chains 41 are wound around the handrail driving sprockets 40 as shown in FIG. 4 . The handrail driving chain 41 is provided to drive a handrail driving device 43 ( FIG. 2 ) via deflection rollers 42 . The handrail drive 43 is arranged to drive the return channel side of the moving handrail 21 inside the railing 20 in a known manner.

Due to the adoption of the above structure, the space required when the tooth portion of the drive sprocket 33 is located between the bearing 16 and the handrail drive sprocket 40 is no longer needed, and considering the balance of the main frame 4 and the railing 20, etc. And the same space that needs to be reserved between the drive sprocket 13 and the bearing 16 on the side where the drive sprocket 33 is not provided is no longer necessary. As a result, the entire width of the main frame 4 can be reduced, thereby reducing the size of the escalator 1. Sets the width dimension Wo.

In addition, since the driving mechanism 35 is arranged outside the moving track in the turning portion of the steps 18 in the length direction, compared with the structure in which the driving mechanism is installed around the driving shaft 15, no steps will be blocked for maintenance. There is no maintenance space, so the driving mechanism 35 can be repaired and maintained more conveniently.

When installing the narrow escalator 1 with the above-mentioned structure in a narrow place in a building, such as an existing staircase in a station, as shown in FIG. The wall W on one side is provided, and the handrail 20 on the opposite side to the wall W of the escalator 1 is used as a partition between the stairs S and the escalator 1 . When the escalator 1 with the installation width Wo is installed on the stairs S in this way, the width dimension that the pedestrians of the stairs S can use will become narrower, but the width of the installation width Wo of the escalator 1 will become smaller as described above. Narrow, so the reduction of the effective width of the staircase S can be controlled within the minimum range.

Moreover, since the railing balustrade 24 that should be vertically arranged on the position of the peripheral portion 29 and the base portion 30 is recessed toward the outer side of the escalator 1 to form a recess, even if the passenger takes the hand-carried The luggage faces the side of the railing balustrade 24, and since the hand luggage is less likely to be in contact with the railing balustrade 24, passengers can take the passenger conveyor at ease.

In addition, due to the terminal portion in the longitudinal direction of the railing balustrade 24, an inclined portion 32A is formed at the railing balustrade 24 formed as a concave portion, and it is inclined so that the inclined extension line of the inclined portion 32A does not intersect with the handrail frame 23. The angle is inclined, so when a passenger arrives at the exit side while his hand luggage is still in the recess of the railing panel 24, even if he walks out of the passenger conveyor in this state, the hand luggage is moved toward the steps along the inclined portion 32A. Side guide, so carry-on luggage will not collide with the guide member that guides the moving armrest 21, that is, the back side of the armrest frame 23, so it is possible to avoid falling accidents due to the collision of carry-on luggage.

Fig. 7 shows another embodiment of the present invention, and it compares with above-mentioned embodiment, and it is the structure of railing that difference is larger, and the structure of main frame, step and the drive mechanism of moving handrail are then the same as above-mentioned
