Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a traveling speed (speed and / or speed).
Or, it relates to a connecting and transporting device equipped with a plurality of steps in different directions, and contributes to the escalator of narrow stairs and the speeding up of moving walkways in long-distance passages.

[0002]

2. Description of the Related Art In conventional escalators and moving walkways, the steps or belts that run between the left and right skirt guard panels are single rows and single speeds. There is a method of joining different transporting means in series, but there is no parallel method.

[0003]

SUMMARY OF THE INVENTION A structure and drive mechanism of a double row step or belt having different speeds are developed while avoiding an increase in the number of parts as much as possible.

[0004]

[Means for solving the problem] In the case of a conventional type step and a method similar to a drive type escalator / moving sidewalk, a single-seater step row is provided in two rows in parallel with an intermediate wall interposed. , One is driven at low speed, the other is driven at high speed, or both are driven in opposite directions, but the chain gear or belt wheel for driving may be rotated at one speed at low speed, the other speed at high speed, or one and the other at the opposite direction. . In the case of moving walkways such as airports where the transport distance is extremely long, and escalator that elevates and lowers many floors at once, the steps return unnecessarily, so the utilization rate of the steps is low, and generally there are sturdy existing stairs and passages. If you have to break and lay them,
The position of the tread becomes higher when it is used without breaking. The above-mentioned drawbacks can be avoided by using a system in which the tread surface is always upward and the forward stroke and the backward stroke are connected. As an example, a method using a parallel link mechanism by the present inventor (Japanese Patent Application No. 1-23
0453, 1-241770, 2-016070, etc.)
In the case of using, at the turning parts at both ends, the inner step sequence is applied with the escalator method to lower the tread surface,
A small sprocket (attached to the mandrel shaft) meshes with the pin-shaped tooth provided on the lower side of the tread, and the pin-shaped tooth provided on the lower side of the tread of the outer step has a coaxial shaft concentric with the small sprocket. When the large sprocket attached is engaged and the mandrel shaft and the mandrel are separately driven by electric motors, both large and small sprockets can be given different speeds. When both are integrated, the inner speed is low and the outer speed is high. In order to facilitate the transfer, a high speed moving handrail is preferably provided in parallel with the low speed moving handrail on the low speed side. In addition, since power is transmitted by parallel links (provided on the inside) that can bend each step row around the vertical axis at the turning portion, a means for preventing twisting of the step (for example, a roll provided on the step is perpendicular to the rail). Add a mechanism that applies a moment to the side to release the twist) or use a direct-acting slat-chain mechanism (described in Japanese Patent Application No. 4-157260, etc.) outside the high-speed step. Is desirable.

[0005]

OPERATION As an application example, the operation will be described in the case where an escalator having a reciprocating path on an existing narrow stairway and a moving sidewalk capable of high speed movement are laid on a long-distance passage.

When converting an existing staircase to an escalator,
Due to cost and space, many are only for climbing. However, the stairs are painful for the elderly and dangerous for the descending, and it is desirable that the stairs are set as a set. As a method of dealing with a limited width, a wide step is divided into two and run in opposite directions. Since there are moving railings on each step, there is no safety problem. Kicking up and the depth of the step may be reduced in order to make it easier to walk on the step. For example, if the inclination angle α of the inclined traveling section is 30 ° and the depth A is 30 cm, the kick-up H is 15 cm,
The weight per unit width of the steps is 0.75 times the square of the current level, that is, it is halved, but the number of steps is 4/3 times, and the total weight is 3/4 times. It also makes it easier to walk as stairs. Both can go up or down depending on the passenger flow. The width of the steps depends on the allowable width of the installation place, and if each row is about 50 cm, one side is 80 cm to allow wheelchair mounting and the other side is 50 cm.
If so, both can be installed in a wheelchair 80 cm
There are cases such as The escalator that can be mounted on a wheelchair is not limited to a specific escalator, but according to the invention “Large-sized object connecting and transporting device” filed by the present inventor on June 7, 1995, a complicated mechanism is not required. It is suitable for application to the present invention because the step-related part for mounting a shape is automatically formed, and if the present invention is used, it is necessary to stop other steps while the wheelchair is mounted. There is an advantage that you can use it without switching, and you can use the wheelchair-mounted steps by switching between up and down, and by using other steps by selecting the driving direction according to the flow of general passengers. .

A long-distance aisle has the same level as the floor surface, a walkway that moves at the level raised by the escalator, and a structure in which the escalator descends and the back side is returned immediately above the floor. Minimize construction (digging, etc.) Small steps are effective for height reduction. Speed is the most effective application to moving walkways. That is, if the low speed side is set to 30 m / min and the high speed side is set to double the same direction, that is, about 60 m / min, it is not difficult to move from the low speed step to the high speed step during traveling. If a leading handrail with a speed almost the same as the speed of the high-speed step is provided on the low speed side and the user walks while being guided by it, it is possible to move more safely and without shock. If the high speed leading handrail on the low speed side is used, it is possible to safely move from the high speed step to the low speed step. If an ultra-high-speed leading handrail (about 60 m / min) in which the walking speed is added is provided on the higher speed side, walking on the high-speed step and separation from it can be safely performed with a small shock. Also, when the sidewalk that is moving in the opposite direction is not driving, to compensate for it, use the running directions of both steps as the opposite direction (the speed is the same, the speed of the moving handrail is similar). The leading handrail is according to Japanese Patent Application No. 6-211664 by the present inventor.

When shifting between a low speed step and a high speed step in an inclined traveling section with an escalator, since it has a step-like shape, it must be executed more carefully than in the case of a moving sidewalk, but basically it is the same. .

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As a preferred embodiment for explaining the present invention, the actual conditions of the conventional type and the parallel link mechanism type will be described in the case where a moving walkway that utilizes an existing passage as much as possible is used as the main stroke. .

FIG. 1 is a plan view of the entire traveling route when a conventional drive system is used, and FIG.
The low-speed running part is the low-speed sprocket winding part 10,
It consists of a boarding horizontal low-speed traveling unit 11, an ascending low-speed escalator unit 12, a low-speed moving sidewalk unit 13, a descending low-speed escalator unit 14, a disengaging horizontal low-speed traveling unit 15, a low-speed sprocket winding unit 16, and a back-side low-speed returning unit 17, and a low speed Side skirt guard panel 18, slow-moving handrail 1
81, high-speed moving handrail 182, low-speed sprocket 19
1, 192 are provided, and the high-speed traveling section includes a high-speed sprocket winding section 20, a boarding horizontal high-speed traveling section 21, an ascending high-speed escalator section 22, a high-speed moving sidewalk section 23, a descending high-speed escalator section 24, a leaving horizontal high-speed traveling section 25, a high-speed traveling section. Sprocket winding part 26, back side high speed return part 27,
This is equipped with a high speed side skirt guard panel 28, a high speed side high speed handrail 281, and high speed sprockets 291, 292, and an intermediate panel 3 (moving at a fixed speed and an intermediate speed between the low speed step row and the high speed step row). There is something to do). It is desirable that the high-speed handrails be extended above the floor to ease the shock when boarding / leaving, and to assist walking before and after boarding. If the ultra-high-speed moving handrail 282 in which the walking speed on the tread is added is provided on the higher speed side, the occupant can move at a higher speed and the shock is reduced when the passenger leaves the high-speed tread. When a belt is used instead of the step, the inclination angle of the inclined traveling portion is made considerably smaller than the friction angle between the back belt of the footwear.

If the step chain pulls the center of the step, it is less likely to twist the step, but for safety, two step chains are used for each step, and an example of a step chain drive mechanism is used. Show. FIG. 3 shows an example in which a gear transmission is used together with the single electric motor 9 when the steps of each row have the same size.
1. Drive the large drive sprocket 81 from the small drive sprocket 94 via the drive chain 901 through the external meshing gears 92, 93 to drive the coaxial step chain sprout 82, 83. On the other hand, from the speed reducer 91 to the slip shaft 9
From the slip gear 95 on 50, through the intermediate gear 96 on the slide shaft 960, mesh with the external gear 97, and drive the large drive sprocket 84 from the coaxial small drive sprocket 98 via the drive chain 902, The step chains sprockets 85 and 86 are driven, and the step chains 850 and 860 are driven to move each step row. The external gears 92, 93, 95, 97 have the same size, and the left and right steps are moved in opposite directions. If the electric motor is reversed, the direction of movement is reversed. When the intermediate gear 96 is slid over the gear shaft 960 to disengage it and the gear 93 is slid over the gear shaft 930 and meshed with the gear 97, both steps are moved in the same direction. FIG. 4 shows an example in which the lateral width Sa is enlarged and the lateral width Sb of the right step is reduced so that the left step row can be used for transporting a large object such as a wheelchair, and both step rows are driven by separate variable speed electric motors. Indicates. The electric motors 9a and 9b adopt the pole number conversion inverter gear shifting system, and each of the reduction gears 91
drive small sprockets 99a, 99b through a, 91b
Drive large sprocket 84a, 84b via the drive chain 98a, 98b, and coaxial step chain sprocket 85a, 86a and 82b, 83b
To drive each step row through the step chains 850a, 860a and 850b, 860b.
As a result, any of low speed, high speed, and reverse rotation can be performed for each step sequence, and the degree of freedom of operation is high. Since the loads of both motors fluctuate, they are connected in parallel to complement each other to save power.

When the parallel link mechanism is used, as shown in FIG. 5 (plan view) and FIG. 6 (side view), the first turning section 4 is used.
The forward stroke and the backward stroke are connected by 1 and the second turning section 42, and the speed (direction
The size is different, and the arrangement of steps from the boarding horizontal traveling section to the leaving horizontal traveling section is the same as the conventional type, but the shape near the turning section is different. 7 (plan view) and FIG.
(Side view) shows an example of the structure of the turning part. It is a method of driving pin-shaped teeth fixed to the step with a sprocket having a vertical central axis, and the inner step 5 inside is sunk in an escalator type. Turn the tread surface 50 inside the inner step 5.
Pin-shaped teeth 51 and 52 provided perpendicularly to the small sprocket 6
The outer sprocket 8 for driving the outer step 7 and the inner step 5 are prevented from interfering with each other by driving the large sprocket 8 with the pin-shaped teeth 7 perpendicular to the outer step surface 70.
The structure is such that the outer step 7 is driven by meshing with 1 and 72. In order to avoid driving twist, as shown in FIG. 7, the front and rear of the vertical surface 020 on the side opposite to the vertical surface of the rail 02 on which the brim of the wheel 75 of the step 7 (the same applies for the case 5) is hit. The rollers 021 and 022 are pressed. The rail shape is determined so that the rollers do not interfere with each other at the turning portion. When the large sprocket 8 and the small sprocket 6 are driven integrally, the inner speed is low and the outer speed is high (the direction is the same). Large sprocket 8 and axle 8
0, the outer shaft 60 is provided on the small sprocket 6, and each of them is provided with a separate electric motor 8 via hypoid gears 801 and 601.
By driving with the No. 02, 602 and the speed reducers 803, 603, various speed combinations are possible.

In any case, when the number of steps is three or more, the traveling speed of each row can be gradually increased to facilitate the movement between the rows.

[0014]

According to the present invention, a step row or belt having two or more different speeds (speed and / or direction) can be obtained, and even in narrow passages and stairs, it can be used as a reciprocating type, high and low. Escalators and moving walkways with various functions such as speed type and wheelchair mountable type can be obtained, which contributes to improvement of operation efficiency and contribution to social welfare.
