Technical field

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 high-lift escalators have been installed at subway stations. 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, reduce the time spent in Escalai by running 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 high-speed escalation one-night sloping section has been proposed. Such a high-speed escalating escalating section is disclosed in, for example, Japanese Patent Application Laid-Open No. 5-11 / 1686.

However, in the conventional high-speed escalation at a slope, the speed ratio (speed ratio) between the speed of movement of the steps at the upper and lower entrances and the lower entrance and exit is the speed of the steps at the middle slope. The setting was not considered. If the gear ratio is too small, the effect of shortening the travel time cannot be expected. On the other hand, if the gear ratio is too large, the steps between the steps will increase at the intermediate slope, making it difficult for passengers to walk on the steps in an emergency or the like. Disclosure of the invention

The present invention has been made to solve the above-described problems, and has an intermediate inclination. The aim is to obtain a high-speed escalation at the slope where a moderate step can be secured at the slope.

A high-speed escalator with an inclined portion according to the present invention includes a circulation path having an upper entrance / exit portion, a lower entrance / exit portion, and an intermediate inclined portion located between the upper entrance / exit portion and the lower entrance / exit portion. It has a plurality of steps that are connected endlessly and circulate and move along the circulation path, and the speed ratio of the speed of the steps on the intermediate slope to the speed of the steps on the upper and lower entrances and exits is 2 It is as follows.

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 escalator with a slope 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. Above the main frame 1, a pair of balustrades 4 are erected. Balustrades 4 are arranged on both sides of step 2 in the width direction.

The main frame 1 is provided with a drive rail 5 that forms a circulation path for the step 2, a follow-up rail 6 for controlling the attitude of the step 2, and an auxiliary rail 7 for changing the interval between the adjacent steps 2. Have been. The circulation path of Step 2 has a forward section, a return section, an upper reversing section and a lower reversing section. In the forward section of the circuit, the upper entrance (upper horizontal section) A, upper curved section B, middle inclined section (constant inclined section) C, lower curved section! ), And a lower entrance (lower horizontal part) E.

Next, FIG. 2 is an enlarged side view showing the vicinity of the upper entrance / exit portion A and the upper curved portion B of FIG. The step 2 is a tread plate 8 on which a passenger is placed, a riser 9 bent at one end in the front-rear direction of the tread plate 8, a drive roller shaft 10, a pair of drive rollers 11 rotatable around the drive roller shaft 10, and a follower. It has a roller shaft 12 and a pair of following rollers 13 rotatable about the following roller shaft 12. The drive roller 11 rolls along the drive rail 5. The following roller 13 rolls along the following rail 6.

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. The other end of the first link 15 is rotatably connected to an intermediate portion of the third link 17 via a shaft 20. 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 a fifth link 19 is rotatably connected to an intermediate portion of the second link 16. 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 an auxiliary rail 7.

When the auxiliary opening roller 22 is guided by the auxiliary rail 7, the link mechanism 14 is transformed to bend and elongate, and the distance between the drive roller shafts 10, that is, the distance between adjacent steps 2 is changed. . Conversely, adjacent steps 2 are assisted so that the distance between them changes. The track of rail 7 is designed.

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 A and the lower entrance / exit E where passengers get on and off, the interval between the drive roller shafts 10 is minimum, and the steps 2 move at low speed. In the middle inclined portion C, the interval between the drive roller shafts 10 is maximum, and the steps 2 move at high speed. Further, in the upper curved portion B and the lower curved portion D, the interval between the driving 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 a symmetrical axis. 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 distance 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 5 and the auxiliary rail 7 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 5 and the auxiliary rail 7 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.

Next, FIG. 3 is an explanatory diagram showing an example of an arrangement state of the steps 2 in the intermediate inclined portion C of FIG. In this example, the gear ratio is 1.5, the depth of the tread 2 is about 400 mm, and the inclination angle of the intermediate inclined portion C is 30 °. These depth dimensions and inclination angles are the same as the standard Escalé overnight. It is considered that when the gear ratio increases, the distance between the drive port and the shaft 10 in the intermediate inclined portion C increases, and the step between the steps 2 also increases. As can be seen from the figure, when the gear ratio is 1.5, the step between the steps 2 is about 30 Omm (about 200 mm in standard ESCARE overnight).

This step is a dimension that allows the passenger to easily walk on the step 2. Therefore, in the event of an emergency stop of the escalator, for example, passengers can walk on step 2 smoothly. You can move around. Also, if the gear ratio is 1.5, the time to reach the adjacent floor is reduced by about 30% compared to a normal non-shifting Escalé overnight, and the effect of shifting the steps can be obtained sufficiently.

Next, FIG. 4 is an explanatory diagram showing another example of the arrangement state of the steps 2 in the intermediate inclined portion C in FIG. In this example, the gear ratio is 2, the depth of the tread 2 is about 400 mm, and the inclination angle of the intermediate inclined portion C is 30 °. As can be seen from the figure, when the gear ratio is 2, the step between the steps 2 is approximately 400 mm. This step is considered to be almost the limit for passengers to walk on step 2.

Therefore, the gear ratio is preferably set to 2 or less. If the gear ratio is set to 1.8 or less, the steps can be reduced, and passengers such as children with small steps can easily walk on the steps 2. In particular, as shown in Fig. 3, if the gear ratio is 1.5, all passengers can walk on the steps 2 smoothly.

In addition, if the gear ratio is theoretically larger than 1, an effect of shortening the time can be obtained, but in practice, it is preferable to be 1.2 or more. In other words, if the gear ratio is 1.2 or more, the traveling time is reduced by about 20% or more, so that many passengers can feel the effect of reducing the traveling time. Embodiment 2

FIG. 5 is a side view showing an essential part of a high-speed escalating section at an inclined portion according to Embodiment 2 of the present invention, and FIG. 6 is an exploded configuration view showing the link mechanism of FIG. In the figure, a drive rail 31, a follower rail 32 and an auxiliary rail 33 are provided on a main frame (not shown). The main frame is provided with a plurality of steps 34 connected endlessly.

Each step 34 is a pair of steps 35 on which passengers can be placed, a riser 36 bent at one end in the front-rear direction of the steps 35, a drive roller shaft 37, and a drive port shaft 37. It has a drive roller 38, a follow roller shaft 39, and a pair of follow rollers 40 rotatable about the follow roller shaft 39. The drive roller 38 rolls along the drive rail 31. The follower roller 40 rolls along the follower rail 32. c The drive roller shafts 37 of the steps 34 adjacent to each other are connected to a pair of link mechanisms (refracting ring). H) are connected to each other by 41. Each link mechanism 41 has first and second links 42, 43 and an auxiliary roller 44 that rolls along an auxiliary rail 33.

One end of the first link 42 is rotatably connected to the drive roller shaft 37.c The other end of the first link 42 is rotatably mounted with an auxiliary roller 44. You. One end of the second link 43 is rotatably connected to an intermediate portion of the first link 42 via a shaft 45. Further, the other end of the second link 43 is rotatably connected to the drive roller shaft 37 of the adjacent step 34.

The first link 42 has a linear first portion 42 a connected to the drive roller shaft 37 and a linear second portion 42 b to which the auxiliary roller 44 is attached. are doing. The second part 42b forms a predetermined angle with the first part 42a. Thus, the first link 42 has a shape bent in a direction away from the second link 43. The first portion 42a and the second portion 42b may be integrated or separate.

In such a high-speed escalating section at an inclined portion, as in Embodiment 1, the distance between the drive rail 31 and the auxiliary rail 33 is changed depending on the position, so that the link along with the movement of the step 34 is changed. Mechanism 41 is bent. As a result, the interval between the steps 34 is changed, and the moving speed of the steps 34 is changed. In addition, in the link mechanism 41 of this type, the number of link connecting portions (bearing portions) is minimized, and the influence of gas friction is greatly reduced.

Also, even in the high-speed escalating section in the inclined section according to the second embodiment, the passenger can smoothly walk and move on the steps 34 by setting the gear ratio in the range of 1.2 or more and 2 or less. And the time to reach the adjacent floor can be reduced sufficiently.
