Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a passenger conveyor, and more particularly to a passenger conveyor with an improved step guide rail.

[Conventional technology]

Escalators, which are traditional passenger conveyors,
As shown in Figures 1 to 3, there is a handrail section 1 that stands upright on both sides of the passenger, a panel 1a that constitutes this handrail section 1, an outer deck 1b, an inner deck 1c, a skirt guard 1d, and this skirt guard. 1d, a support 1f on which a passenger is fixed, a step 2 disposed in an endless manner for carrying a passenger, a step chain 3 that continuously engages and rotates the step, and a step chain 3 that rotates by continuously engaging the step. A front wheel 4 adjacent to the step 2 that rolls while supporting the front part of the step 2, a front wheel guide rail 5 having a U-shaped cross section on which the front wheel 4 rolls, and a rear wheel 6 that rolls while supporting the rear part of the step 2. As is well known, the rear wheel 6 is composed of a rear wheel guide rail 7 having an L-shaped cross section on which the rear wheel 6 rolls, and a frame 8 that supports the whole of these.

[Problem to be solved by the invention]

In an escalator having such a configuration, as shown in FIGS. 2 and 3, the front wheel guide rail 5
(1) As shown in Fig. 4, the front wheel 4 is connected to the front wheel guide rail 5.
When assembling the vehicle into the vehicle, the flange portion 5a provided above the front wheel guide rail 5 to prevent the front wheel 4 from lifting up, etc. becomes an obstacle and cannot be incorporated. For this purpose, it is necessary to provide a portion (not shown) in a portion of the entire length of the front wheel guide rail 5 where the flange portion 5a is removed, and furthermore, in this removed portion, after the front wheel 4 is assembled, the front wheel 4 is raised. In order to suppress this, the flange portion 5a must be attached by some method, and the work is complicated.

Furthermore, since the flange portion 5a can only be removed from a limited location, the location where the front wheel 4 can be assembled is also limited, resulting in poor workability.

(2) It was about three times as large as the rear wheel guide rail 7, and it was difficult to manufacture and work.

In order to solve the above problem, there is a method that installs a lifting control rail separately from the guide rail.
No consideration was given to the assembling of the anti-lifting rail, and the assembling work was extremely troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger conveyor that allows easy installation of running wheels of steps and lifting prevention rails.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a lifting prevention rail for preventing the running wheels of the steps from lifting up, in addition to the guide rail having an L-shaped cross section. A plurality of support members are provided in the longitudinal direction of the frame, and the vertical sides of the uplift prevention rail are positioned on the step side, and a plurality of support members for supporting the skirt guard are provided in the longitudinal direction of the frame. A support portion for the uplift suppressing rail is provided on each of the supporting members, and the vertical side of the uplift suppressing rail is attached to the support portion with a bolt.

〔Example〕

Embodiments of the present invention will be described below with reference to FIG. In the figure, the main components such as a parapet 1, steps 2, step chain 3, and a front wheel 4, which is one of the running wheels, are the same as before, but in this embodiment, the conventional front wheel guide rail 5 is replaced by a front wheel guide rail 20. and a lifting suppression rail 30, and the lifting suppression rail 30 is disposed above and parallel to the front wheel guide rail 20.
Moreover, the lifting-up suppressing rail 30 is formed in an L-shape including a horizontal side 30H and a vertical side 30V standing upright from one end of the horizontal side 30H. The horizontal side 30H suppresses the front wheel 4 running on the front wheel guide rail 20 from lifting up.

On the other hand, the skirt guard 1d is supported by the frame 8 by the support body 40, as in the conventional case.
A plurality of these supports 40 are provided in the longitudinal direction of the frame 8, and each support body 40 includes a support portion 40a that supports the skirt guard 1d and a support portion 40b that supports the lifting prevention rail 30, respectively.
and. Support body 4 configured in this way
The lifting prevention rail 3 is attached to the support portion 40b of 0.
0 vertical side 30V is attached with bolts and nuts.

With the above structure, when the step 2 is assembled into the rear wheel guide rail 7 and the guide rail 20, at least the inner deck 1c, the skirt guard 1
d. Before the anti-lifting rail 30 and optionally the support 40 are installed, the rear wheel 6 is placed on the rear wheel guide rail 7 and the front wheel 4 is placed on the front wheel guide rail 20. After that, if the support body 40 is not attached, the support body 40 is attached to the frame 8, and then the lifting-up suppressing rail 30 is attached to the frame 8.
Attach the vertical side 30V of the front wheel guide rail 20 with bolts and nuts so that it is parallel to the front wheel guide rail 20.
When installing this lifting suppression rail 30,
Since the vertical side 30V is close to the step 2 side, the worker can stand on the step 2 without taking an unreasonable posture.
It can be attached to the a support part 40b.
Thereafter, the inner deck 1c and the skirt guard 1d are attached to complete the installation of the steps 2 onto the respective guide rails 7 and 20.

As described above, according to the embodiment of the present invention, it becomes easy to assemble the front wheel 4 of the step 2, and the assembling work of the lifting prevention rail 30 is also facilitated.
Support body 40 for attaching uplift suppression rail 30
Since it is provided on the support body 40 of the skirt guard 1d, there is no need to attach an extra support body, and the assembly structure is also simplified.

Furthermore, since the front wheel guide rail 20 and the uplift prevention rail 30 are L-shaped, they have substantially the same cross-sectional shape as the rear wheel guide rail 7, which not only facilitates manufacturing but also allows parts to be shared.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to simplify the work of assembling the step running wheel into the guide rail, and also to simplify the work of assembling the uplift prevention rail and the assembly configuration.
