Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a passenger conveyor such as an escalator,
In particular, the present invention relates to the structure of the main body frame of such a passenger conveyor.

[Background of the invention]

The running path of a passenger conveyor, that is, an escalator, which connects different floors is composed of an inclined part and horizontal parts at both ends, and the side surface shape is curved at the connection part between the inclined part and the horizontal part. ing.

Therefore, the side shape of the parapet that guides the handrail also has curved parts A and B, as shown in Figure 2. In addition, in this FIG. 2, 1 represents a parapet, and 2 represents a main body frame.

On the other hand, in conventional escalators, the main body frame 2 made of a truss structure, etc., is made straight in both its inclined and horizontal parts, and the connecting part between them is straight. Also, curved parts are not included.

Therefore, in the conventional escalator, the lower part of the parapet l cannot be directly attached to the upper part of the main body frame 2, and it is necessary to use a large number of supports C, as shown in FIG. 2, for example.

This will be explained with reference to FIGS. 3 and 4.

The examples shown in FIGS. 3 and 4 are constructed with a main body frame 2tf and a shaped steel 2a. From these figures, it can be seen that the lower end of the parapet panel 1a and the upper end of the shaped steel 2a of the main body frame are It can be seen that the members 1d for attaching the inner deck 1b and the outer deck IC to the main body frame 2 are held via a number of supports C, and this is the same for the main body frame of the truss structure shown in Fig. 2. . In addition, in these Figures 3 and 4, 3 represents the step and 4 represents the handrail.

Therefore, in conventional passenger conveyors, the structure of the attachment part of the handrail to the main body frame is complicated and requires many parts.
As a result, the number of assembly steps increases, resulting in a disadvantage that a sufficient cost reduction cannot be achieved.

Note that such a passenger conveyor is known, for example, as disclosed in Japanese Utility Model Application No. 56-92658.

[Object of the Invention] An object of the present invention is to provide a passenger conveyor in which the structure of the attachment part of the handrail to the main body frame is extremely simple, and the cost can be easily reduced, by eliminating the drawbacks of the prior art described above. .

[Summary of the invention]

In order to achieve this objective, the present invention makes the main body frame of a passenger conveyor such that the main part for its strength is a side plate made of two plates, thereby changing the side shape of the upper end of the main body frame to a parapet. It is characterized by being made to match the side shape of the lower end of the.

[Embodiments of the invention]

EMBODIMENT OF THE INVENTION Hereinafter, the passenger conveyor according to the present invention will be explained in detail with reference to illustrated embodiments.

1 and 5 show an embodiment of the present invention. In these figures, 20 to 24 are members constituting the main body frame 2tf, 20 is a pair of left and right side plates, 21 is a bottom plate, 2
2 is an upper chord member, 23 is a vertical member, and 24 is a bottom reinforcing member.

A pair of side panels 20 and a bottom panel 21 are formed by bending flat plates of a predetermined length, and are joined together over a plurality of pieces to obtain the length required for the main body frame 2. At this time, as is clear from FIG. 1, the side surface shape of the upper edge portion is designed to include a curved portion in accordance with the shape of the lower edge portion of the balustrade 1.

The upper chord member 22 is a shaped steel member that is fixed to the upper end of the side plate 20 almost continuously along the length direction of the passenger conveyor and integrally therewith, so that it plays the role of a beam for strength. , its upper surface serves as a mounting surface for the parapet l.

Vertical member 23. The bottom reinforcing material 24 is a shaped steel member that is arranged along the side plate 20 and the bottom plate 21 at a predetermined interval and is integrally fixed thereto.
It serves to suppress distortion caused during the manufacturing of the bottom plate 21 and distortion caused by stress tf.

Furthermore, the upper chord material 22. Vertical member 23. The bottom reinforcing members 24 are welded and fixed to each other to form a framework, and the side plates 20 and the bottom plate 21 are fixed to this by spot welding or the like that causes little welding distortion.

At this time, as shown in FIG.
If you match the mounting position of the side plate 20 and bottom plate 2
The seam welding of step 1 and the welding and fixing of the vertical members 23 and bottom reinforcing members thereto can be performed in the same process. Therefore, the occurrence of welding distortion can be further reduced.

In this way, according to the above embodiment, as shown in FIG. 1, it is possible to directly attach the lower edge of the handrail 1 to the upper edge of the main body frame 2, reducing the number of required members. Next, the attachment of the balustrade l to the main body frame 2 will be explained with reference to FIG. 7.

As shown in FIG. 7, the upper chord member 21 made of shaped steel is attached to the upper end of the side plate 20, and a panel support 30 is maintained at a predetermined interval on the back side sandwiching the side plate 20. The railing panels Xa (see FIG. 3 and FIG. 4) are held as appropriate in the length direction of the passenger conveyor.

The upper surfaces of the panel support 3o and the upper chord member 22 also serve as mounting surfaces for the outer deck 31 and outer molding 32, and these can be mounted using bolts 33. Note that 25 is attached by connecting the left and right vertical members 23, and serves to prevent the side plate 21 including the vertical members 23 from falling down, and also serves as a member for attaching a rail (not shown) for step running. 34 represents the exterior plate.

Therefore, according to this embodiment, since the shape of the upper edge portion of the main body frame 2 where the upper chord member 22 is provided is made to match the shape of the lower part of the balustrade l, the balustrade panel la is Installation can be done by simply providing panel supports 30 at any part of the entire passenger conveyor, and no special members are required for attaching the outer deck 31 or outer molding 32. Since this can be done by simply using the top surface, the configuration and assembly are simple and costs can be reduced significantly.

Next, another embodiment of the present invention is shown in FIG.

In the embodiment shown in FIG. 8, the side panels 20 and the bottom panel 21 (not shown) are connected to the upper chord member 22. The longitudinal members 23.degree. and the bottom reinforcements 24 (not shown) are provided on the outside, and the rest is the same as the embodiment shown in FIG.

According to this embodiment, the same advantages as the embodiment shown in FIG.
Since no other parts are attached to the outer surface of the side panel 20, the outer surface of the side panel 20 and the bottom panel 21 may be subjected to appropriate treatment, such as applying cosmetics or painting, or applying an exterior panel. 34, and depending on market needs, it is possible to provide sufficient commercial value at low cost.

Further, FIG. 9 shows yet another embodiment of the present invention, in which the side plate 20 and the bottom plate 21 were formed into one bent product in the embodiment shown in FIG. The system is divided into two parts and then welded together when assembling the passenger conveyor, which has the effect of making it easier to transport the parts.

〔Effect of the invention〕

As explained above, according to the present invention, the main body frame is formed of a flat plate material reinforced with a framework body, so that the side shape of the upper edge matches the shape of the lower edge of the parapet. Since the parapet can be attached almost directly to the main body frame, it is easy to provide a man conveyor that eliminates the drawbacks of the conventional technology, requires fewer types and numbers of parts, and requires less assembly man-hours, allowing for sufficient cost reductions. Be able to do it.
