Description

[Detailed description of the invention] [Industrial application field] The invention is a belt type in which an endless tread belt is wound between a belt driving pulley and a belt tension pulley, and a passenger riding on an upper surface of the belt is transferred. It is about a moving sidewalk.

[Prior Art] In recent years, a so-called moving sidewalk that transports personnel using an endless tread belt does not need to take a complicated structure like a conventional stair-type escalator. An endless tread belt is wound between them, and a guide roller for guiding the tread belt is only required between the driving pulley and the belt tension pulley.

In addition, in the thickness direction, it is sufficient if there is a space for reciprocation of the belt, so that the belt can be made thin, so that it can be easily installed on a flat floor surface.

The movable part is a flat belt, which gives a comfortable ride and is safe, and it does not slip like metal. Therefore, it has attracted attention as a means of transportation for stations, department stores, shopping centers, and parking lots.

Moving walkways have various advantages, as described above.
In addition, while the length can be freely selected by changing the length of the belt, it is inevitable that the belt is stretched due to aging during use because the belt is used.

For this reason, conventionally, a tread belt is wound between a driving pulley and a tension pulley, and a predetermined tension is applied to the tension belt by always applying a predetermined tension output by a spring or a cylinder to the tension pulley. Has become. (See JP-A-58-34867) [Problem to be Solved by the Invention] However, the longer the tread belt, the greater the elongation and the longer the stroke for belt tension. For this reason, a large space for accommodating a tensioning device that moves the tension pulley to apply tension to the tread belt is required.

Therefore, when installing on a road surface, it is necessary to dig wide and deep pits. In addition, when installing on the floor of a building, problems such as punching the floor and tensioning the lower floor were inevitable.

On the other hand, there is also known a belt conveyor in which a weight is attached to a tension pulley via a rope, and the weight is lowered by gravity to move the tension pulley. (See Japanese Utility Model Publication No. 34-7794 and Japanese Utility Model Publication No. 34-9368) However, the tensioning device using the known weight is not a heavy footboard (slat) or a moving sidewalk device for transporting a person. The tower and columns are specially erected near the tension pulley, and the weight is suspended.Therefore, a special space must be prepared for erecting the towers and columns, and the tower, columns and weight There was a risk that the weights would become dangerous goods and harm humans. Furthermore, installing the turret or column near a moving sidewalk will impair the appearance of the moving sidewalk.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a belt-type moving sidewalk belt tensioning device which can solve the above-mentioned drawbacks, is simple in structure, does not require special space, and has no danger.

Means for Solving the Problems A feature of the present invention is a belt type in which an endless tread belt is wound between a belt driving pulley and a belt tension pulley, and a passenger riding on an upper surface of the belt is transferred. On a moving sidewalk, a belt tension pulley is placed on a take-up trolley, and the trolley is connected to a balance weight via a connecting member such as a wire rope or a chain. It is stored in the wall of a building.

[Embodiment] Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings.

Reference numeral 1 denotes a moving sidewalk main body, which is provided in an installation pit P such that the upper surface of an endless tread belt 2 is flush with an installation surface G such as a road surface or a floor surface.

The tread belt 2 is wound between a belt driving pulley 3 and a belt tension pulley 4.

The tension pulley 4 is rotatably mounted on a take-up cart 7 having wheels 6 movable on a take-up stand 5.

One end of a connecting tool 8 such as a wire rope or a chain is attached to the take-up cart 7, and the other end of the connecting tool 8 has guides 9a, 9b,
Balance weight provided in the wall 10 of the building via 9c
Connected to 11.

The balance weight 11 is guided by a balancer guide 12 installed in the wall body 10 and is supported so as to be able to move up and down.

13 is a support bracket for supporting the guides 9a, 9b, 9c, 14 is a side wall panel erected on the left and right sides of the tread belt 2 along the moving direction of the belt 2, and 15 is a wrap around the side wall panel 14. The handrail belt moves in synchronism with the tread belt 1.

 Next, the operation will be described.

When the belt tension pulley 3 is driven, the tread belt 2 is moved to the first position.
Move in the direction indicated by the arrow in the figure. At this time, the tread belt is always applied with a predetermined tension by the belt tension pulley 4 which is pulled by the balance weight 11 with a predetermined force, so that the tread belt does not slack. When the tread belt 2 is stretched by use, the balance weight 11 is increased by an amount corresponding to the stretch.
Is lowered and the tension pulley 4 is moved to the left in FIG. 3 to make the tension applied to the tread belt 2 constant.

[Effects of the Invention] According to the present invention, the balance weight can be stored in the wall of the building or in an empty space, so that the space used for installing the tensioning device is not crushed or the floor is punched, and the space efficiency is improved. Also has the effect of improving.

Also, since there is no need to specially set up the tower and columns near the tension pulley, no special space is required for erecting the tower and columns, and the tower, columns and weights become dangerous materials. There is no danger of harm to people.
