Description

Memorandum Description High-speed escalation at slope

The present invention relates to a high-speed escalator for a slope, in which the moving speed of a step at an intermediate slope is faster than the moving speed of a step at an upper entrance and a lower entrance. Background art

In recent years, many subway stations, etc., have installed many high-rise escalations. In this type of escalating overnight, passengers must stand still for long periods of time on the steps, and many passengers feel uncomfortable. For this reason, high-speed S-power has been developed, but there is an upper limit to the speed at which passengers can get on and off safely.

On the other hand, it is possible to reduce the time spent on the escalator by operating at low speed at the upper and lower entrances where passengers get on and off, accelerating and decelerating at upper and lower bends, and operating at high speed at intermediate slopes. A sloping high-speed escalation overnight has been proposed. Such a high-speed escalation at an inclined portion is disclosed, for example, in Japanese Patent Application Laid-Open No. S5-11-1686.

In the conventional high-speed escalating section, the moving speed of the step is changed by changing the distance between adjacent steps, that is, the distance between the drive roller shafts of the adjacent steps. At the mouth, the step is moved at low speed by reducing the distance between the drive roller shafts of adjacent steps. Further, in the intermediate inclined portion, the step is moved at a high speed by increasing the distance between the drive roller shafts of the adjacent steps.

However, in the conventional high-speed escalator with inclined section, the distance between the drive roller shafts of adjacent steps on the intermediate inclined section becomes large. Longer than the riser. Therefore, in order to avoid interference of parts between the forward path and the return path and interference of the parts at the reversal part, The dimensions (thickness dimensions) increase. Disclosure of the invention

The present invention has been made to solve the above-described problems, and has an object to obtain a high-speed escalator having an inclined portion that can suppress a height of a cross section even when a long step body having a riser is used. I do.

A high-speed inclined section escalator according to the present invention includes: a step main body including a main frame, a tread plate, and a riser; a drive roller shaft extending in a width direction of the step main body; a drive roller rotatable around the drive roller shaft; A plurality of steps that are endlessly connected, circulate and move, are provided on a main frame, and have a following roller shaft that is rotatable about the following roller axis. A drive rail that forms a path and envisages a drive roller, a guide rail that is provided on the main frame, guides the follow roller, and controls the attitude of the step, connects the drive roller shafts of the steps adjacent to each other, and transforms. A plurality of link mechanisms for changing the distance between the drive roller shafts, auxiliary rollers provided on the link mechanism, and an auxiliary roller provided on the main frame to guide the auxiliary rollers. An auxiliary rail that transforms the link mechanism and changes the moving speed of the step according to the position is provided.The following roller is arranged between the step body, the link mechanism, and the auxiliary roller in the width direction of the step.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Embodiment 1

FIG. 1 is a schematic side view showing a high-speed escalation at an inclined portion according to Embodiment 1 of the present invention. In the figure, a main frame 1 is provided with a plurality of steps 2 connected endlessly. The step 2 is driven by a drive unit (step driving means) 3 and is circulated.

On both sides of the step 2 of the main frame 1 in the width direction, a pair of drive rails 4 forming a circulation path of the step 2, a pair of following rails 5 for controlling the posture of the step 2, and an adjacent step 2 are provided. A pair of auxiliary rails 6 for changing the interval are provided.

The circulation path of Step 2 has a forward section, a return section, an upper reversing section and a lower reversing section. The forward section of the circuit is the upper entrance (upper horizontal section) A, upper curved section B, middle inclined section (constant inclined section) C, lower curved section D, and lower entrance section (lower horizontal section). Part) E.

Next, FIG. 2 is an enlarged side view showing the vicinity of the upper turning portion in FIG. Step 2 rotates about a pair of drive rollers 11, a follow-up roller shaft 12, and a follow-up roller shaft 12, which are rotatable about a step body 7, a drive roller shaft 10, and a drive port roller shaft 10. It has a pair of free following rollers 13. The step body 7 has a step board 8 on which a passenger is placed, and a riser 9 erected at one end of the step board 8 in the front-rear direction. The drive roller 11 rolls along the drive rail 4. The following roller 13 rolls along the following rail 5.

The drive roller shafts 10 of the steps 2 adjacent to each other are connected to each other by a pair of link mechanisms (refraction links) 14. Each link mechanism 14 has first to fifth links 15 to 19.

One end of the first link 15 is rotatably connected to the drive roller shaft 10 .c The other end of the first link 15 is connected to the intermediate portion of the third link 17 by the shaft 2. It is rotatably connected via 0. One end of the second link 16 is rotatably connected to the drive roller shaft 10 of the adjacent step 2. The other end of the second link 16 is rotatably connected to an intermediate portion of the third link 17 via a shaft 20.

One end of a fourth link 18 is rotatably connected to an intermediate portion of the first link 15. One end of the fifth link 19 rotates around the middle of the second link 16 They are freely connected. The other ends of the fourth and fifth links 18 and 19 are connected to one end of a third link 17 via a sliding shaft 21.

At one end of the third link 17, a guide groove 17 a for guiding the sliding of the sliding shaft 21 in the longitudinal direction of the third link 17 is provided. A rotatable auxiliary roller 22 is provided at the other end of the third link 17. The auxiliary roller 22 is guided by the auxiliary rail 6.

When the auxiliary roller 22 is guided by the auxiliary rail 6, the link mechanism 14 is deformed so as to bend and extend, so that the distance between the drive roller shafts 10 of the adjacent steps 2, that is, the distance between the adjacent steps 2 is reduced. Be changed. Conversely, the track of the auxiliary rail 6 is designed so that the distance between the adjacent steps 2 changes.

Next, FIG. 3 is a cross-sectional view taken along the line III-III in FIG. The drive roller shaft 10 protrudes from both ends in the width direction of the step body 7. The drive roller 11 is attached near the tip of the drive roller shaft 10. The link mechanism 14 is attached to the drive roller shaft 10 between the step body 7 and the drive roller 11.

The drive rail 4, the follower rail 5, and the auxiliary rail 6 are arranged in parallel with the widthwise end surfaces 7 a and 7 b of the step body 7. The follow roller shafts 12 protrude from both ends of the step body 7 in the width direction. The following roller 13 is attached near the tip of the following roller shaft 12.

The follower rail 5 and the follower roller 13 are disposed between the step body 7 and the link mechanism 14, the auxiliary roller 22, and the auxiliary rail 6 in the width direction of the step 2 (left-right direction in FIG. 3). I have. In other words, the follower rail 5 and the follower roller 13 are arranged outside the step 2 in the width direction and inside the link mechanism 14, the auxiliary roller 22 and the auxiliary rail 6. In the intermediate inclined portion C, the follower rail 5 and the follower roller 13 are arranged within the range of the thickness of the step body 7.

Next, the operation will be described. The speed of the step 2 is changed by changing the distance between the drive roller shafts 10 of the adjacent steps 2. That is, at the upper entrance / exit portion A and the lower entrance / exit portion E where passengers get on and off, the distance between the drive roller shafts 10 of the adjacent steps 2 becomes minimum, and the steps 2 move at low speed. In the middle inclined portion C, the interval between the drive roller shafts 10 of the adjacent steps 2 is maximized, and the steps 2 move at high speed. Further In addition, in the upper curved portion B and the lower curved portion D, the interval between the drive roller shafts 10 is changed, and the step 2 accelerates and decelerates.

The first, second, fourth and fifth links 15, 16, 18 and 19 constitute a so-called pan-graph-type quadruple link mechanism, and the third link 17 is connected to the axis of symmetry. As a result, the angle between the first and second links 15 and 16 can be increased or decreased. As a result, it is possible to change the interval between the drive port shaft 10 connected to the first and second links 15 and 16.

At the entrances A and E in FIG. 1, the distance between the drive roller shafts 10 of the adjacent steps 2 is minimized. In this state, if the distance between the drive rail 4 and the auxiliary rail 6 is reduced, the link mechanism 14 operates in the same manner as the umbrella frame when the umbrella is spread, and the drive roller shaft of the adjacent step 2 The interval of 10 increases.

In the middle inclined portion C in FIG. 1, the distance between the drive rail 4 and the auxiliary rail 6 is the smallest, and the distance between the drive roller shafts 10 of the adjacent steps 2 is the largest. Therefore, the speed of step 2 is maximum in this region. In this state, the first and second links 15 and 16 are arranged substantially in a straight line.

In the inclined high-speed escalator as described above, the follower roller 13 is disposed between the step body 7 and the link mechanism 14 and the auxiliary roller 22 in the width direction of the step 2, so that the step body 7, the link The vertical position of the follower rail 5 can be set without interference with the mechanism 14, the auxiliary roller 22, and the auxiliary rail 6.

For this reason, even if the vertical position of the following roller 13 and the following rail 5 overlaps the vertical position of the step body 7 and the link mechanism 14, the following roller 1 remains at all positions in the circulation path of the step 2. 3 and the following rail 5 can be configured so as not to contact any of the step body 7 and the link mechanism 14. Therefore, the interval between the forward path and the return path in the inclined portion can be reduced, the reversal radius in the reversal portion can be reduced, and the height of the cross section can be suppressed.

In the first embodiment, the auxiliary roller 22 is disposed on the opposite side of the step body 7 of the link mechanism 14. However, the auxiliary roller 22 is disposed on the side of the step body 7 of the link mechanism 14. Is also good. Also in this case, if the follower roller 13 is disposed between the step body 7 and the auxiliary roller 22 in the width direction of the step 2, the follower roller can be disposed at all positions in the circulation path. The configuration may be such that the track 13 and the follower rail 5 do not contact either the step body 7 or the link mechanism 14. Embodiment 2

Next, FIG. 4 is a side view showing an essential part of a high-speed escalation section at an inclined portion according to Embodiment 2 of the present invention. In the figure, the drive roller shafts 10 of the adjacent steps 2 are connected to each other by a link mechanism (refractive link mechanism) 31. The link mechanism 31 according to the second embodiment has a simpler structure than the link mechanism 14 according to the first embodiment.

The link mechanism 31 has a first link 32 having a bend at an intermediate portion, and a second link 33 having a linear shape. One end of the first link 32 is connected to the drive roller shaft 10. An auxiliary roller 22 is attached to the other end of the first link 32. One end of the second link 33 is connected to the drive roller shaft 10 of the adjacent step 2. The other end of the second link 33 is connected to an intermediate portion of the first link 32 via a shaft 34. Other configurations are the same as those of the first embodiment.

Even when such a link mechanism 31 is used, if the follower roller 13 is disposed between the step body 7 and the link mechanism 31 and the auxiliary roller 22 in the width direction of the step 2, It is possible to obtain a high-speed escalation all over the slope that can suppress the height of the cross section.
