Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving sidewalk.

[0002]

2. Description of the Related Art At present, most of the moving sidewalks practically used at airports and the like move at a constant speed at a speed at which a pedestrian on a stopped road can get on and off, but the user can easily get on and off. It has been pointed out that a speed that is as slow as possible is too slow to take a long time to move.

[0003] For this reason, it is desired that a user can easily get on and off the vehicle, and that a moving sidewalk having a high moving speed be put to practical use. For example, Japanese Utility Model Application No. Hei 6-15851 (registered utility model publication No. 301168). No.), a large part of the moving walkway is composed of a long belt conveyor driven at high speed, and a plurality of speed differences are gradually provided near the entrances at both ends in the longitudinal direction. Short belt conveyors are connected in series, and at the entrance, transfer from the slower belt conveyor to the faster belt conveyor at the entrance, while at the exit, from the faster belt conveyor to the successively slower belt conveyor. I'm trying to make it transfer.

[0004]

However, in such a moving sidewalk, when a user walks on a long belt conveyor driven at a high speed and closes an empty space with a user in front of him, he gets down. As the vehicle approaches the mouth, it gradually moves onto a belt conveyor having a slow speed, and when the moving speed is reduced, users may be crowded and the exit may be crowded.

[0005] As a countermeasure against such congestion at the exit, in the above-mentioned conventional invention, the congestion state of a user on a long belt conveyor driven at high speed is detected, and when the congestion is severe, the operation speed of each belt conveyor is determined. However, if the operation speed of each belt conveyor is reduced to eliminate the congestion, the original purpose of shortening the traveling time cannot be achieved.

A section where the moving speed is accelerated near the entrance and a section where the moving speed is reduced near the exit are constituted by a plurality of belt conveyor groups requiring an independent drive system. There is also a problem that a large construction cost is required for a moving sidewalk having a complicated structure that requires a detection device for detecting the congestion state and a speed control device.

The present invention has been made in view of the above-mentioned circumstances, and enables a user to easily get on and off without causing congestion at the exit even when the moving speed is increased.
The aim is to provide a moving walkway that can significantly reduce construction costs.

[0008]

SUMMARY OF THE INVENTION According to the present invention, a main sidewalk is constituted by a large number of pallets continuously circulating on an endless track comprising a plurality of straight portions and curved portions, and a plurality of pallets in the straight portion of the track are provided. Variable traction means for towing each pallet while changing the moving speed over a required range is provided at each location, and the pallets are gradually and deeply overlapped by each of the variable speed traction means, thereby moving the pallets by reducing the transportation road surface. A deceleration section in which the speed is gradually reduced, and an acceleration section in which the pallets that are superimposed on each other in the deceleration section gradually separate from each other to gradually increase the traveling speed by extending the transport road surface. An auxiliary sidewalk composed of a number of pallets circulating along an endless track similar to the main sidewalk, similar to the main sidewalk, and partially running parallel to the deceleration section of the main sidewalk A synchronous traction means is provided so that the pallet in the range can be synchronized with the pallet moving in the deceleration section of the main sidewalk over a required range of the auxiliary sidewalk running parallel to the deceleration section of the main sidewalk. It is characterized by the following.

With this configuration, even if the traveling speed of the main sidewalk is increased, the user can easily get on and off the vehicle using the end point of the deceleration section as the exit and the starting point of the acceleration section as the entrance. In addition, the auxiliary sidewalk partially running parallel to the deceleration section of the main sidewalk makes it possible to expand the area of the transportation road surface in front of the exit and avoid crowding of users.

Further, the required range of the acceleration section and the deceleration section of the main sidewalk and the auxiliary sidewalk running in parallel with the deceleration section are merely towed by the variable speed traction means and the synchronous traction means which can be covered by one drive system, respectively. Acceleration and deceleration can be performed by changing the moving speed of each pallet, and additional equipment such as a detection device for detecting the congestion state of the user and a speed control device are not required, so the structure is significantly simplified. Construction costs are greatly reduced.

A variable-speed traction means for towing each pallet while changing the moving speed, and moving the pallets in the range through the deceleration section of the main sidewalk over a required range of the auxiliary sidewalk running parallel to the deceleration section of the main sidewalk. Synchronous pulling means for pulling in synchronism with the pallet to be set, means that a cam follower projecting from the lower surface on the front end side of each pallet is disposed along a linear portion of the track so that the cam follower can be engaged with a screw thread and rotated. It can be constituted by a screw rod formed such that the pitch of the thread becomes gradually smaller in the direction in which the moving speed of the screw becomes relatively lower.

Are arranged along the straight portion of the track so that the cam followers 11 on the lower surface on the front end side of each pallet 2 can be engaged and rotated between the threads 14 (see FIG. 7), and the moving speed of each pallet 2 is relatively high. The screw rods 15 and 16 are formed so that the pitch P of the screw thread 14 gradually decreases toward the lowering direction.

That is, the screw rods 15 and 16 in the acceleration section 4 and the deceleration section 5 have the pitch P of the thread 14.
The only difference is that the direction in which is gradually reduced is opposite, and the other configuration is the same. In both the acceleration section 4 and the deceleration section 5, the screw rods 15, 16 , The shaft portions 17 at both ends in the longitudinal direction
