Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a truss support device for a passenger conveyor, and particularly to an improvement in a movement limiting device that limits the range of movement of a passenger conveyor truss movable in a horizontal plane.

[Prior Art] Figures 4 and 5 show conventional truss support devices for passenger conveyors. The welded support angle (3) is a receiving plate provided on the upper floor (4) and lower floor (5) of the building, and the support angle (2) has a washer on this receiving plate (3). (6) placed through;
It is fixed to the receiving plate (3) via bolts (7). (
8) is a step built into the truss (1).

The conventional truss support device for a passenger conveyor is constructed as described above, with the truss (1) supporting the upper floor (4) and the lower floor (5).
) is adopted. However, in recent years, as buildings become taller and traffic conditions become more three-dimensional, there is a tendency for super-large passenger conveyors to become necessary. In such a passenger conveyor, the dimensions between the upper and lower floors (4) and (5) become larger, and the upper and lower floors (4) may be damaged due to earthquakes, strong winds, changes in ambient temperature, etc.

(5) A displacement difference occurs. For this reason, when the truss (1) is made into a fixed structure, an excessive external force acts on the truss (1), causing an increase in member stress and deformation of the truss (1). In addition, it promotes deformation of the running track of the steps (8), which reduces the running accuracy of the steps, which are the heaviest part of a passenger conveyor, and may cause an accident.

Therefore, some proposals have been made, for example, as shown in Japanese Utility Model Publication No. 50-21277, in which the man-compare truss is made into a support structure capable of sliding in a horizontal plane.

6 to 10 show a conventional truss support device for a passenger conveyor of this type, in which the same reference numerals as in FIGS. 4 and 5 indicate the same or corresponding parts.

<9) is a threaded member (10) on the underside of the support angle (2).
The slide piece (11) attached via the receiving plate (3
) is welded onto the slide seat (12) on which the slide piece (9) slides, and (12) is the support angle (2) on the receiving plate (3).
) is a movement limiting device that restricts the sliding range of the support angle (2). ) and one end of which protrudes without contacting the upper surface of the support angle (2). When welding the above-mentioned shape material (13) and flat plate material (14), as shown in Fig. 9, first weld the top of the L-shaped material (13) by chamfering (15).
At the same time, this L-shaped material (13) and flat plate material (14)
are welded by groove welding (16) and fillet welding (17) as shown in FIG. The distance between the two is set to a as shown in FIG.

[Problems to be Solved by the Invention] In the conventional truss support device for a passenger conveyor as described above, when welding the L-shaped member (13) and the flat plate member (14) as described above, the chamfering process is first performed. (15), groove welding (1B) and fillet welding (17), and then cutting the built-up part (18) of the groove welding (16), making the welding process complicated. There was a problem that the cost was high.

This invention was made in order to solve these problems, and it is possible to easily weld the L-shaped material and the flat plate material, thereby reducing the cost.Moreover, it reduces thermal distortion during welding, making it easier to eliminate distortion. The purpose of the present invention is to obtain a truss support device for a passenger conveyor that can simplify the process.

[Means for Solving the Problems] A truss support device for a passenger conveyor according to the present invention is provided by welding an L-shaped member and a flat plate constituting a movement limiting device by fillet welding, and by welding the fillet of the support angle. A relief is provided at a portion corresponding to the welded portion.

[Function] ゛In this invention, the L-shaped material and the flat plate material are welded by fillet welding, so the welding work is easier than groove welding, and the distance between the welds is shortened. It is possible to reduce distortion due to heat and simplify distortion work. In addition, since a relief is provided at a portion of the support angle corresponding to the fillet weld, there is no problem even if fillet weld is performed.

[Embodiment] FIGS. 1 to 3 show an embodiment of the present invention, and in the figures, the same reference numerals as in FIGS. 4 to 1O indicate the same or corresponding parts. The top of the L-shaped member (13), which together with the flat plate (14) constitutes the movement restriction device (12), is not chamfered;
) is placed, and the L-shaped member (13) is made by fillet welding (17).
is welded to. By making fillet welds (17) on both sides, the distance between the welds is Jl as shown in Figure 3.
llb is longer than the distance Jlia shown in FIG. Also, the fillet weld (17) of the support angle (2)
) is chamfered to provide a relief (18) as shown in FIG.

In the truss support device for a passenger conveyor constructed as described above, the L-shaped member (13) and the flat plate member (14) are welded together by fillet welding (17), which is superior to groove welding. Welding work is easy, and the distance ab between welded parts is small.
increases, so distortion due to heat is reduced and distortion removal work becomes easier. Furthermore, since the support angle (2) is provided with a relief (18), there is no problem in performing fillet welding (17).

[Effects of the Invention] As explained above, in this invention, the L-shaped material and the flat plate material are welded together by fillet welding, so the welding work is easy, and the distance between the welded pieces increases, so it is less likely to be caused by heat. Distortion is reduced and distortion removal work can be simplified. Also, since a relief is provided in the part corresponding to the fillet weld of the support angle, there is no problem in answering the problem even if the support angle is welded by fillet.
