[Problems to be Solved by the Invention]
Although there is a tendency for the depth to increase, in the conventional escalator type elevating and conveying device shown in FIGS. 8 and 9, when the subway line has a large depth, the vertical shaft excavation area becomes large and the construction cost increases. In addition, the conventional elevator-type lifting and lowering transportation device has a problem that the transportation capacity is small due to the batch processing and congestion occurs at the peak time.

The present invention was developed to address such problems, and it is an object of the present invention to provide a carrier device for efficiently carrying a large amount of personnel and luggage continuously between deep underground and above ground. And

[0006]

The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 and 2 corresponding to the embodiments. The present invention is directed to a vertical direction between the carriage 2 and the carriage 2. And a driving device 9 for driving the conveyor 1 which is connected endlessly so as to be slidable with respect to each other and can be rotated in a horizontal plane to form a conveyor 1 circulating between the upper layer floor H and the lower layer floor L. With upper and lower floors H,
A guide rail G3 for horizontal movement for guiding the conveyor 1 is provided on L, and an upper floor H and a lower floor L are further provided.
It is characterized in that an inclined guide rail G7 is provided between the two.

[0007]

According to the present invention, by the above means, the vertical slide amount between the carriages is set to zero in the entry / exit portion of the upper and lower floors, and the conveyor is slowly moved horizontally at a low speed.
In the ascending / descending section between the upper floor and the lower floor, the horizontal speed should be constant and the vertical slide amount between the bogies should be gradually increased to accelerate in the vertical direction. Stop and the conveyor moves up and down at full speed.

Further, when the upper and lower floors get closer to the boarding / alighting section, the vertical sliding amount between the bogies is gradually reduced to reduce the vertical speed, and the vertical sliding amount between the bogies becomes zero at the boarding / alighting section. Then, the conveyor moves slowly in the horizontal direction at low speed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG.
FIG. 2 shows a cross section taken along the line AA of FIG. In FIGS. 1 and 2, L is a lower layer floor, H is an upper layer floor, 1 is a conveyor for carrying personnel and luggage between the upper layer floor H and the lower layer floor L, and T is between the upper layer floor H and the lower layer floor L. An inclined shaft 100 is a boarding / alighting conveyor that assists the boarding / alighting of the conveyor 1.

FIG. 3 is a plan view showing the structure of the conveyor 1, and FIG. 4 is a front view of FIG. In FIGS. 3 and 4, 2 is a dolly, 3 is a lower roller provided on the left and right under the dolly 2, 4a is a bracket provided on the dolly 2, 4b is a slide shaft attached to the bracket 4a, and 5a is the dolly 2 The bracket mounted on the opposite side of the bracket 5b is a slide bush mounted on the bracket 5a, and the slide shaft 4b is inserted into the slide bush 5b.
The two are connected so that they can be rotated in a horizontal plane and can slide in the vertical direction. Reference numeral 6 is a shaft attached to the left and right of the center of the upper portion of the carriage 2, and 7 is an upper roller provided at the tip of the shaft 6. 8 is a rack link, 8
a is a pin connecting the rack links, 8b is a spherical bush provided between the rack link 8 and the shaft 6,
Rack links 8 connect between shafts 7 provided on the carriage 2.

As described above, the slide shaft 4b
1 between the carriage 2 and the slide bush 5b and the rack link 8 for driving the conveyor 1.
Connect endlessly as shown in. FIG. 5 is a simplified diagram of the elevating part of the transport device of FIG. 2, and in the figure, 9 is a drive device that drives the rack link 8 and the meshing conveyor 1. G7 is a guide rail for guiding the upper roller 7,
G3 is a guide rail for guiding the lower roller 3.

Next, the raising / lowering of the device of the present invention will be described with reference to FIG. 7. FIG. 7 is a diagram for explaining the principle of acceleration / deceleration during raising / lowering. In FIG. 5, when the transport device moves horizontally, the lower roller 3 is guided by the guide rail G3. When moving up and down, the upper roller 7 is guided by the guide rail G7. In the elevating part, when the guide rail G7 is gently raised, the slide amount between the carriages 2 gradually increases, and the carriage 2 is accelerated in the vertical direction.

In FIG. 7, the movement of the horizontal portion of the conveyor 1 from the X point to the X'point changes to the movement of the elevating portion of the conveyor 1 from the Y point to the Y'point. When the horizontal speed is Vx, the vertical speed is Vy, and the inclination angle of the elevating part is Θ, the relationship of tan Θ = Vy / Vx (1) is established. Therefore, if the inclination angle Θ is increased, the speed of the conveyor 1 in the vertical direction increases.

According to the above-mentioned principle, the conveyor 1 moves horizontally in the boarding / alighting section, so that the vertical slide amount is zero, and the conveyor 1 moves horizontally slowly at a low speed.
On the other hand, in the elevating unit, the vertical slide amount between the carriages 2 is gradually increased to accelerate in the vertical direction. In the high speed section,
Stop the carts 2 from sliding on each other, and conveyer 1
Moves up and down at maximum speed. When approaching the boarding / alighting area again, trolley 2
The vertical slide amount is gradually reduced to reduce the vertical speed, and the vertical slide amount between the carriages 2 is set to zero in the boarding / alighting section, and the conveyor 1 slowly moves in the horizontal direction. ..

The curved movement of the apparatus of the present invention will be further described with reference to FIG. 6. FIG. 6 shows the movement of the corner portion of the conveying apparatus of FIG. The conveyor 1 is guided by the guide rails G7 and G3, and at that time, rotation between the slide shaft 4b and the slide bush 5b connecting the carriage 2 and the rack link 8 by the spherical bush 8b.
The conveyor 1 can be bent due to the bending.

In this embodiment, the rack link is used as the drive system of the conveyor, but the linear motor system can be applied and the drive system is free.

[0017]

As described above, according to the present invention, the bogies can be slid vertically with respect to each other and connected endlessly so that they can rotate in a horizontal plane and circulate between the upper and lower floors. It is formed on the conveyor, and a guide device for driving the conveyor is provided and a horizontal movement guide rail for guiding the conveyor to the upper and lower floors is provided, and an inclined elevating guide rail is provided between the upper floor and the lower floor. Since it is provided, the elevating part is nearly vertical, and it is sufficient to construct one uphill and one downhill, so construction costs are higher than when constructing a large vertical shaft such as an escalator system. In addition, it is easy to get on and off the personnel and to load and unload baggage at the boarding / alighting section because it moves slowly at a low speed horizontally. Continuously people and cargo between deep underground and ground, etc., and has an effect such as can be a large amount conveyed at a relatively high speed.
