Abstract

PURPOSE:To cope with a high floor height or long span by welding and mounting support metal fittings supported by bearing parts of a structure in plural positions along the vertical direction of each end part of a frame. CONSTITUTION:L-shaped support metal fittings 11a, 11b are welded and mounted to the end part of a frame body 2 along the vertical direction. The support metal fittings 11a, 11b are placed on the bearing beams 13a, 13b of a structure 12 to position an escalator or moving road, as occasion demands, by using a liner 14 together. Then, all the support metal fittings 11a, 11b are regulated and bolted so as to equalize their loads. In this way, the number of support metal fitting is increased to reduce the load to the support metal fitting, allowing the conformation with a high floor height or long span.

Description

[Detailed Description of the Invention] [Object of the Invention (Industrial Application Field) The present invention relates to an escalator or a moving road, and in particular,
This relates to the structure of the frame.

(Prior Art) As is well known, in an escalator or a moving road, a handrail, endlessly connected steps or treads, a drive device for driving the steps or treads, etc. are attached to a frame, and both ends of this frame are connected to a structure. It is installed by being supported by something (for example, a building).

3 and 4 show the configuration of one end of this pedestal 1. An L-shaped support 3 is attached to the pedestal main body 2 by welding, and this support 3 is attached to a structure (not shown). It was supported by a support beam provided and fastened with bolts (not shown).

(Problem to be Solved by the Invention) With the above-described configuration, all the load from the escalator or moving road is applied to the welded part, and the welded part between the frame body 2 and the support fitting 3 has a high quality. requested,
Welding work also requires a large amount of labor, which has been a constraint on the production of escalators for high floor heights or moving roads for long spans.

Therefore, the purpose of the present invention is to reduce the load applied to the welded parts of the support fittings by adding and attaching simple members without changing the basic configuration, and to be able to accommodate higher floor heights or longer spans. It consists in providing escalators or moving roads.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a railing, which is connected in an endless manner to a pedestal in which a supporting metal fitting attached to an end by welding is placed on a supporting part of a structure and supported. escalators or moving roads equipped with steps or treads and a drive device for driving these steps or treads, in which supporting metal fittings are attached by welding to each end of the pedestal at multiple locations along the vertical direction. It is.

(Function) Since multiple support metal fittings are attached to each end of the frame by welding, the load applied to the weld between each support metal fitting and the frame decreases in inverse proportion to the number of support metal fittings. . This makes it possible to increase the permissible support load without changing the basic structure of the conventional escalator and to manufacture an escalator or a moving road that can accommodate higher floor heights or longer spans than conventional escalators or moving roads.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing essential parts of an embodiment of the present invention;
FIG. 2 is a sectional view taken along line A--A in FIG. 1.

In FIGS. 1 and 2, the pedestal 10 has the above-mentioned support fittings 3 attached to the end of the pedestal main body 2, which has the same structure as the conventional one.
Similarly, L-shaped support fittings 11a and llb are attached by welding at two locations along the vertical direction. Here, the support fittings 11a and Ilb have the same shape, and lla
The pitch L1 of the supporting metal fittings 11a and Ilb is
Support beams 13 provided on the structure 12 to support each
The pitch should be smaller than the pitch L2 between a and 13b.

In addition, in the above, the supporting metal fitting 11 is attached to one end of the gantry main body 2.
Although the configuration is shown in which the mounts a and Ilb are attached, the support fittings 11a,
Attach llb by welding.

Next, when installing an escalator or a moving road, first attach the support fittings 11a and Ila at both ends to the structure 1.
Place it on the support beams 13a and 13a of liner 1 as necessary.
4 is used in combination to position escalators or moving roads. After this, the other supporting metal fittings 11b and IIb and the support beam 1
3b, 13b, adjust so that the load is evenly applied to all the supporting metal fittings 11a, flb, and then tighten the supporting metal fittings 11a, ll with bolts (not shown).
b to the support beams 13a and 13b, respectively.

Note that in the above, the support fittings 11a and Ila at both ends were placed on the support beams 13a and 13a, respectively, and positioned. You may also do so.

Therefore, with the above configuration, the load applied to the welded parts of the frame body 2 and the supporting metal fittings 11a and Ilb at both ends is reduced to 1/2 of the conventional one, and the stress generated in the welded parts is also reduced to 1/2 of the conventional one. It becomes 2.

[Effects of the Invention] As explained above, according to the present invention, by increasing the number of support fittings provided at each end of the pedestal, the load applied to the welded portion between each support fitting and the pedestal is reduced. This makes it possible to provide an escalator or a moving road that can accommodate higher floor heights or longer spans than conventional ones.
