Description

Passenger Conveyor

technical field

The present invention relates to passenger conveying devices such as escalators and electric walkways for conveying passengers, and more particularly, to a passenger conveying device that can ensure safety even when pedal wheels are abnormal.

Background technique

Conventional passenger conveyors have also taken measures in terms of how to ensure the safety of passengers in the event of an abnormality in the pedal wheels. Especially in the scheme disclosed in Patent Document 1, in addition to the guide rails used to guide the walking of the pedal wheels, support rails are additionally provided. The upper surface of the support rail is supported to prevent a gap from appearing between the comb plate and the pedal arranged at the entrance.

Patent Document 1 JP-A-2-132093 (page 3, FIG. 2 )

However, in the scheme disclosed in the above-mentioned Patent Document 1, the guide rail and the support rail are fixed by bolts, so there is a possibility of oil leakage in the step chain. In addition, since the guide rail and the support rail are formed separately, the rigidity is low, and the manufacturing method is complicated, resulting in an increase in cost.

Contents of the invention

Therefore, the object of the present invention is to provide a passenger conveying device which can not only ensure the safety of passengers when the pedal wheel is abnormal, but also prevent oil leakage of the step chain, improve rigidity, simplify the manufacturing method, and the like.

In order to achieve the above object, the passenger conveying device of the present invention has the pedals that are connected in a loop to move cyclically, the railings that are oppositely arranged on both sides along the moving direction of the pedals, and the moving handrails that are guided and moved by the circumference of the railings; A portion for guiding a wheel provided in the step and a guide rail for a portion supporting the step from below when an abnormality occurs are integrally formed.

(invention effect)

According to the present invention, it is possible to realize a passenger conveying device that can not only ensure the safety of passengers when the pedal wheel is abnormal, but also prevent oil leakage from the step chain, improve rigidity, simplify the manufacturing method, and the like.

Detailed ways

Embodiments of the present invention will be described below with reference to FIGS. 1 to 4 .

As shown in FIG. 1 , the electric channel 3 is usually set in the setting tunnel 2 excavated in the building and the ground floor 1, and the electric channel 3 has: a frame body 4 arranged in the setting tunnel 2, a The driving sprocket 7 and the driven sprocket 8 are supported by shafts in the mechanical chambers 5 and 6 formed on both ends of the body 4 in the longitudinal direction, and are wound between the driving sprocket 7 and the driven sprocket 8 in an endless shape. The pedal chain 9 between them, the plurality of pedals 10 that are circularly connected to the pedal chain 9 for circular movement, the railings 11 that are vertically arranged in the frame 4 on both sides of the moving direction of the pedals 10, and the A moving handrail 12 which is guided by the periphery of the handrail 11 and a driving device 13 provided in the machine room 5 for driving the driving sprocket 7 .

In addition, the sprocket 20 for power transmission is coaxially fixed to the drive shaft 17, and the chain 22 is wound between the sprocket 20 for power transmission and the output sprocket 21 of the drive device 13, thereby rotationally driving the drive shaft. 17.

The driving device 13 has an electric motor 23 , and a speed reducer 24 that reduces the rotational speed of the electric motor 23 and transmits the rotation to the output sprocket 21 .

In addition, on the upper parts of the machine rooms 5 and 6 located at both ends in the longitudinal direction of the frame body 4 , there are detachably provided entrance and exit floors 25 and 26 for covering the pedals 10 . The direction changing part, and is flush with the surface of the floor 1.

As shown in FIG. 2 , the support shaft 27 is fixed at both ends of the pedal 10 in the width direction, the wheel body 28 is rotatably mounted on the front end of the support shaft 27 , and the wheel rubber part 29 is arranged on the outer periphery of the wheel body 28 . In addition, the pedal chain 9 is connected to the support shaft 27 , and the pedal 10 circulates between the driving sprocket 7 and the driven sprocket 8 . At this time, the wheel body 28 is rotationally moved under the guidance of the guide support rail 30 laid in the frame body 4 , and contacts the guide support rail 30 through the wheel rubber member 29 .

The guide support rail 30 is formed as an integral member and has a U-shaped cross section perpendicular to the moving direction of the pedal 10 . Here, the so-called U-shape includes a shape in which the left and right vertical parts are at right angles to the bottom, and also includes a shape in which the heights of the left and right vertical parts are different. Moreover, the U-shaped guide support rail 30 is provided so that its vertical portion 30A (lower portion) side becomes the inner side of the width direction of the electric passage, and its vertical portion 30B (higher portion) side becomes the electric passage. outside of the width direction. Further, the bottom of the guide support rail 30 on the side of the vertical portion 30B accommodates the wheel rubber member 29 of the outer periphery of the wheel body 28 , and the upper end of the vertical portion 30A faces the bottom of the pedal 10 .

That is, when an abnormality occurs between the guide portions for guiding the wheels provided at both ends of the pedal 10 and the wheels, for example, when the wheel rubber member 29 is detached, the support portion for supporting the pedal 10 from below is integrally formed. In this way, since the guide support rail 30, which also has the function of supporting the pedal when the wheel is abnormal, is formed in a U-shape in an integral manner, that is, it is not assembled from a plurality of independent components, so in terms of parts production and assembly, , rigidity and cost have all been improved.

In addition, normally, the upper surface of the vertical portion 30A of the guide support rail 30 maintains a gap G below the pedal 10, and the pedal 10 is located at the position shown by the solid line in FIG. 3 near the entrance. If there is no supporting part for supporting the pedal 10 from below, once the wheel rubber part 29 breaks away, the pedal 10 will drop to the position shown in dotted line in Fig. 3, so that between the pedal 10 and the comb teeth 31 or with the There will be gaps between the tooth plates 32, which may cause the passenger's feet to be caught therein. That is, by employing the guide support rail 30 as in the present embodiment, the safety of passengers can be ensured even when the wheels are abnormal.

Further, as shown in FIG. 4 , when performing operations such as connecting the pedal chain 9 or installing wheels, the heavy pedal 10 can also be temporarily placed on the frame body 4 by using the upper surface of the vertical portion 30A of the guide support rail 30 . inside, making the work more convenient.

In addition, since the guide support rail 30 with a U-shaped cross section is integrally formed, even if oil drips from the pedal chain 9, it can be collected in the U-shaped guide support rail, so there will be no Oil spill phenomenon.

Again, along the lengthwise direction of the guide support rail 30 (moving direction of the pedal 10), by connecting a plurality of U-shaped guide support rails 30, to ensure the distance between the entrance and exit floor 25 from one side to the other entrance and exit floor 26. length. That is, the cross section of the guide support rail 30 is U-shaped both in the vicinity of the entrance and exit and in the vicinity of the middle portion. In addition, the connecting portion of the adjacent guide support rails 30 is covered from below with the covering member 33 to eliminate gaps and prevent oil leakage or the like from occurring.
