Description

  The present invention relates to an inclined portion high-speed escalator in which the moving speed of the steps in the inclined portion is higher than that of the upper and lower horizontal portions.

  In the conventional inclined portion high-speed escalator, the drive roller shafts of adjacent steps are connected by a link mechanism. The link mechanism is provided with an auxiliary roller. Then, the link mechanism is transformed by changing the distance between the drive rail that guides the drive roller and the auxiliary rail that guides the auxiliary roller according to the position of the circulation path of the step, so that the drive roller shafts of the steps adjacent to each other are transformed. The distance is changed.

  Further, the movement of the driving roller in the reversing section is the same as the movement of the vertex when the polygon having the axis of the driving roller as the vertex rotates. The outer perimeter of the polygon always changes little by little as the step moves. In order to absorb such a change in the outer peripheral length and suppress an increase in the driving resistance force, the reversing portion is provided with a swing rail that guides the movement of the drive roller and swings in accordance with the change in the outer peripheral length. (For example, refer to Patent Document 1).

  However, in the conventional high speed escalator, the swing rail that guides the drive roller at the reversing section can swing, so that the passenger jumps into the step near the entrance and exit to the intermediate slope side. When an external force is applied, there is a possibility that the steps near the entrance / exit will be displaced toward the middle inclined part within the gap between the driving roller and the driving rail and between the auxiliary roller and the auxiliary rail. It was.

  The present invention has been made to solve the above-described problems, and can prevent an unnecessary displacement of a step in the vicinity of the entrance and exit, and can improve the stability of the step. The purpose is to obtain an escalator.

  The inclined portion high-speed escalator according to the present invention is provided with a displacement restricting member for restricting the displacement of the driving roller toward the inner diameter side of the reversing portion so as to face the movable rail on the return path side of the reversing portion.

  In the inclined portion high-speed escalator according to the present invention, the displacement restricting member that restricts the displacement of the driving roller toward the inner diameter side of the reversing portion is provided so as to face the movable rail on the return path side of the reversing portion. Even when an external force is applied, unnecessary displacement of the step near the entrance / exit can be prevented, and the stability of the step can be improved.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic side view showing an inclined high-speed escalator according to an example of an embodiment of the present invention. In the figure, the main frame 1 is provided with a plurality of steps 2 connected endlessly. The step 2 is driven by the drive unit 3 and circulated. The step circulation path includes an outward path section, a return path section, an upper inversion section, and a lower inversion section. The forward path section has an upper entrance / exit part (upper horizontal part), an upper curved part, an intermediate inclined part (constant inclined part), a lower curved part, and a lower entrance / exit part (lower horizontal part).

  A pair of balustrades 4 are erected on the main frame 1 on both sides of the step 2. The balustrade 4 is provided with a moving handrail 4a for preventing passengers from falling. The steps 2 adjacent to each other are connected by a link mechanism 5.

  FIG. 2 is an enlarged side view showing the upper or lower inversion portion of FIG. Each step 2 has a tread plate 6 and a riser 7. Each step 2 is provided with a drive roller shaft 8 and a follow roller shaft 9. A pair of rotatable drive rollers 10 is attached to the drive roller shaft 8. The driving roller 10 is guided by a driving rail 11 supported by the main frame 1 (FIG. 1). A pair of rotatable follower rollers 12 is attached to the follower roller shaft 9. The follower roller 12 is guided by a follower rail 13 supported by the main frame 1.

  The drive roller shafts 8 of the steps 2 adjacent to each other are connected to each other by a link mechanism (refractive link mechanism) 5. Each link mechanism 5 includes a first link 14 having a bent portion at an intermediate portion and a second link 15 having a linear shape. One end of the first link 14 is rotatably connected to the drive roller shaft 8. One end of the second link 15 is rotatably connected to a link connection point located at the intermediate portion of the first link 14 via a shaft 16. The other end of the second link 15 is rotatably connected to the drive roller shaft 8 of the step 2 adjacent to the lower side.

  A rotatable auxiliary roller 17 is provided at the other end of the first link 14. The auxiliary roller 17 rolls along the auxiliary rail 18 supported by the main frame 1. When the auxiliary roller 17 is guided by the auxiliary rail 18, the link mechanism 5 is transformed so as to bend and extend, and the interval between the drive roller shafts 8, that is, the interval between adjacent steps 2 is changed. In other words, the track of the auxiliary rail 18 is designed so that the interval between the adjacent steps 2 changes. Further, the auxiliary rail 18 is formed in a shape such that the opening angle of the link mechanism 5 is maintained at approximately 180 ° in the reversing part and in the vicinity thereof.

  The reversing part moves the driving roller 7 while absorbing a change in the outer peripheral length of a polygon (hereinafter referred to as a polygon having the driving roller axis as a vertex) formed by connecting the axis of the driving roller 10 with a straight line. A movable rail 19 for guiding is provided. The movable rail 19 has an upper swing rail (upper turnmatic) 20 disposed on the forward path side of the reversing unit and a lower swing rail (lower turnmatic) 20 disposed on the return path side of the reversing unit. doing. Each of the upper swing rail 20 and the lower swing rail 21 is a substantially arc-shaped rail. One end of the upper swing rail 20 is pivotally supported by the shaft 20a. One end of the lower swing rail 21 is pivotally supported on the shaft 21a. Further, the shafts 20 a and 21 a are provided on the fixed portion side fixed to the main frame 1.

  The other end of the upper swing rail 20 and the other end of the lower swing rail 21 are connected to each other by a connecting plate 22. The connecting plate 22 is rotatably connected to the upper swing rail 20 and the lower swing rail 21.

  Inside the lower swing rail 21, a pressing rail 23 is provided as a displacement regulating member that regulates the displacement of the driving roller 10 toward the inner diameter side of the reversing portion. The holding rail 23 is provided in the form of extending the drive rail 11 on the return path to the reversing portion, and faces the lower swing rail 21 on the return path side of the reversing portion. Further, the holding rail 23 is continuously provided along the movement locus of the driving roller 10 with a predetermined distance from the lower swing rail 21.

  In such an inclined portion high-speed escalator, even if an external force to the intermediate inclined portion side is applied to the step 2 near the entrance / exit, the displacement of the driving roller 10 in the reversing portion to the intermediate inclined portion side is limited by the press rail 23, Thereby, unnecessary displacement of the step 2 near the entrance / exit is also prevented, and the stability of the step 2 can be improved.

In the above example, the pressing rail 23 is shown as the displacement regulating member, but the rail is not limited to a rail shape as long as the displacement of the driving roller can be regulated.
In the above example, the drive rail 11 on the return path side is extended to be the holding rail 23, but a rail different from the driving rail 11 may be attached as the holding rail.
Furthermore, the structure of the link mechanism is not limited to the above example. For example, a link mechanism having a four-bar link as disclosed in Japanese Patent Application Laid-Open No. 51-116586 may be used.
Furthermore, the present invention may be applied to both the upper inversion unit and the lower inversion unit or to only one of them.

It is a schematic side view which shows the inclination part high speed escalator by an example of embodiment of this invention. It is a side view which expands and shows the upper side or lower side inversion part of FIG.
