Background art

In recent years, many high-rise escalators have been installed in subway stations. In this type of escalating overnight, passengers must stand still for a long time on the steps, and many people feel uncomfortable. For this reason, escalators that operate at speed have been developed, but there are upper limits on the operating speed so that passengers can get on and off safely.

On the other hand, the rider rides on the escalator by moving the step on the intermediate slope relatively higher than on the upper and lower horizontal parts where passengers get on and off. There has been proposed a high-speed escalator with a slope that can reduce the time (see Patent Document 1).

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

FIG. 1 is a diagram showing the entire side surface of a high-speed escalator with a slope according to Embodiment 1 of the present invention, and FIG.

First, the configuration will be described with reference to FIG. 1 and FIG.

The main frame 1 is provided with a rail 2 for a driving roller, a rail 3 for a following roller, and a rail 4 for an auxiliary roller. Step 5 is connected endlessly and circulates along rails 2-4.

The steps 5 include a driving roller 11 that rolls along the driving roller rail 2, a driving roller shaft 12 that supports the driving roller 11, and a following roller. T JP2002 / 012972

A follower roller 13 that rolls along the rail 3 and a follower roller shaft 14 that supports the follower roller 13, a step board 6 on which a person rides, and a riser Consists of seven.

The speed of the step 5 is changed by changing the distance between the adjacent steps 5, in other words, the distance between the drive roller shafts 12 of the adjacent steps 5 (distance between the shaft centers). That is, at the upper entrance A, where the passenger gets on and off, the distance between the center axes of the adjacent drive roller shafts 12 is reduced, and the step 5 moves at a low speed.

The distance between the centers of the adjacent drive roller shafts 12 gradually increases from the upper floor side curved portion B to the constant inclined portion C, and the step 5 shifts to high-speed running.

A link mechanism 20 that changes the distance between the centers of the adjacent drive roller shafts 12 is connected between the adjacent steps 5. The link mechanism 20 has first to fifth links 21 to 25 and an auxiliary roller 15 that rolls along the auxiliary roller rail 4.

One end of the third link 21 is rotatably connected to the drive roller shaft 12. The other end of the first link 21 is rotatably connected to an intermediate portion of the fifth link 25 via a rotation shaft 28. One end of the second link 22 is rotatably connected to the drive roller shaft 12 of the adjacent step 5. The other end of the second link 22 is rotatably connected to an intermediate portion of the fifth link 25 via a rotation shaft 28. A third link 23 is rotatably connected to an intermediate portion of the first link 21. A fourth link 24 is rotatably connected to an intermediate portion of the second link 22. The other ends of the third link 23 and the fourth link 24 are connected to one end of the fifth link 25 via a sliding shaft 29. At one end of the fifth link 25, slide the sliding shaft 29 of the fifth link 25. A guide groove for guiding is provided. At the other end of the fifth link 25, a rotatable auxiliary roller 15 is provided.

Next, the operation will be described. The first, second, third and fourth links 21, 22, 23, 24 constitute a so-called pantograph type quadruple link mechanism, with the fifth link 25 as the axis of symmetry. The angle formed by the first and second links 21 and 22 can be increased or decreased.

Thus, the distance between the drive roller shafts 12 connected to the first and second links 21 and 22 can be changed.

The distance between the drive roller rail 2 and the auxiliary roller rail 4 becomes smaller from the upper floor side curved section B toward the constant inclined section C. At this time, the link mechanism 20 operates similarly to the operation of the umbrella frame when the umbrella is spread, and the distance between the drive roller shafts 12 of the adjacent steps 5 which was in the minimum state at the upper entrance A, is gradually increased. Become larger. In the constant slope portion C, the distance between the driving roller rail 2 and the auxiliary roller rail 4 is minimized, and the distance between the driving roller shafts 2 of the adjacent steps 5 is maximized. Accordingly, the speed of the step 5 reaches the maximum, and the first and second links 21 and 22 in this state are substantially linear.

As described above, at the entrance A on the upper floor where step 5 runs at low speed, the first link 21 and the second link 21 of the link mechanism 20 that connects the drive roller shafts 12 of the adjacent steps are connected. 2 2 is a flexion from which the first link 2 1 and the second link 2 2 gradually linear link mechanism 2 0 in the interval of the upper-floor-side extending portion a ₂ leading to the reversing section F Extend and move to reversal part F. However, the shape of the drive roller rail 2 of the upper floor side reversing part F is an arc shape having no movable part, and the first link 21 and the second link 22 are in the extended state and the reversing part F When moving the roller, use the fixed arc-shaped drive roller In the case of the roller 2, since the movement locus of the driving roller 11 does not match the shape of the driving roller rail 2, a gap or the like is generated between the driving roller 11 and the driving roller rail 2, so that the step 5 is smoothly inverted. Cannot be obtained.

Therefore, in the present invention, when the adjacent step 5 moves on the reversing part, the first link 21 of the link mechanism 20 connecting the respective drive roller shafts 12a and 12b and the second link It is characterized in that the second link 22 is bent at the inverted portion.

Now, if we consider an equilateral polygon where all vertices are located on an arc orbit, if we shorten the length of one side, the vertex at the end of that side will be the inside of the circle, that is, the center of the circle Direction can be displaced. Expressing this as the relationship between the drive roller 11 that moves the reversing part F of the high-speed escalator and the link mechanism 20, the adjacent drive roller shafts 12a and 1 The axis of 2b is the vertex of the equilateral polygon, and the first link 21 and the second link 22 that are linear are sides of the equilateral polygon. Here, when the second link 21 and the second link 22 that connect the adjacent drive roller shafts 12a and 12b are bent, the drive port roller shafts 12a and 12b The distance between the shaft centers of the drive roller shafts Ί2a and 12b is displaced inside the arc.

When the first link 21 and the second link 22 are extended linearly and passed through the reversing part, the axis of the driving roller shafts 1 2 & and 1 2 b is the driving roller rail of the reversing part. If the link mechanism 20 and the drive roller rail 2 are set so that they pass through the outside of the drive roller 2, the drive roller shaft 1 2a and the drive roller shaft〗 2 b The distance between the axis of the drive roller shaft 12a and the axis of the drive roller shaft 12b, which are located outside the arc, is reduced by shortening the distance between Can be driven The axis of the roller shaft 12a and the axis of the drive roller shaft 12b can be kept within the orbital range of the arc-shaped drive roller rail 2 at the reversal portion F.

In order to change the distance between the axis of the drive roller shaft 12a and the axis of the drive roller shaft 12b, the first link 2Ί of the link mechanism 20 and the second link 22 The first link 21 of the link mechanism 20 and the second link 22 of the link mechanism 20 at the upper curved section B and the upper extended section of the high-speed escalator on the inclined section As in the case of controlling the bending and elongation, the reversing section F can be achieved by appropriately changing the distance between the auxiliary roller rail 4 and the arc-shaped drive roller rail 2.

Although only the reversal part on the upper floor has been described above, the same applies to the lower floor.

Accordingly, in the step reversing sections on the upper floor side and the lower floor side, the movement locus of the drive roller and the shape of the guide rail for the drive roller can be matched, and the step can be smoothly reversed. Embodiment 2

FIG. 3 is an explanatory view showing the vicinity of a horizontal portion A and a reversing portion F on the upper floor side of a high-speed inclined escalator according to Embodiment 2 of the present invention. The components shown in FIG. 3 and their operations are the same as those in FIG. 2, and explanations of components having the same reference numerals and overlapping explanations will be omitted.

In the first embodiment, the link mechanism 20 is composed of the first to fifth links as shown in FIG. 2, but in the second embodiment, the link mechanism 20 is formed as shown in FIG. It consists of only the first link 21 and the second link 22. The operation and effect are the same as in the first embodiment. Embodiment 3. Next, a description will be given of a high-speed escalator with a slope according to the third embodiment. FIG. 4 is an explanatory diagram showing the vicinity of a horizontal part A and a reversal part F on the upper floor side of a high-speed escalator with an inclined part according to Embodiment 3 of the present invention. The components shown in FIG. 4 and their operations are the same as those in FIG. 2, and explanations of components having the same reference numerals and overlapping description will be omitted.

The drive roller rail 2 of the upper floor reversing part F in FIG. 4 has an arc shape having no movable part.

In the third embodiment, the interval between the adjacent steps 5 is minimized in the forward horizontal section A, and the interval between the adjacent steps 5 is maximized in the return horizontal section A. When moving in section F, the interval between steps 5 is gradually increased from the horizontal section on the outbound side to the horizontal section on the return side.

In this case, the distance between the drive roller rail 2 and the auxiliary roller 4 is maximized in the forward horizontal section, the first link 21 and the second link 22 of the link mechanism 20 are bent, and the return horizontal In the section, the distance between the drive roller rail 2 and the auxiliary roller rail 4 is minimized, and the first link 21 and the second link 22 are linear. The distance between the drive roller rail 2 and the auxiliary roller 4 is gradually reduced over the horizontal section, and the first link is used in the same way as the upper curved section B and the upper extended section of the high-speed escalator on the inclined section. It controls the bending and elongation of the second link.

As a result, in the step reversing portions at the ends on the upper floor side and the lower floor side, a natural reversal operation of the steps can be performed.

Also, since the length of the horizontal part of the high-speed escalator can be reduced, the high-speed escalator for the high-speed escalator can be manufactured at low cost. Costs can be reduced. Industrial applicability
