Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a passenger conveyor step,
In particular, the present invention relates to a step conveyor device for a passenger conveyor that conveys a heavy step such as a wheelchair step from an entrance / exit to an installation position.

[0002]

2. Description of the Related Art FIG. 4 is a side view for explaining the structure of a main portion of a wheelchair passenger conveyor.

Generally, as shown in FIG. 4, a passenger conveyor for wheelchairs has an ordinary step 1 and, for example, two steps 2 for a wheelchair, which are endlessly connected to each other and circulate, and a step 2 for a wheelchair. Includes a drive device (not shown) for moving the tread 2a up and down.

In the wheelchair passenger conveyer thus constructed, the driving device is driven so that the tread surface 2a of the step 2 is located at the same height as the tread surface 1a of the step 1 located above the tread surface. A relatively wide horizontal surface is formed by 1a and 2a, so that the wheelchair 13 can be mounted.

[0005]

However, in the above-mentioned conventional passenger conveyor for wheelchairs, the steps 2 for wheelchairs are used.
Since the drive unit is installed in the normal step 1,
The weight of the wheelchair is about 150, while the wheelchair step 2 has about 150
It weighs as much as kg. For this reason, when installing the steps 2 for a wheelchair, it is necessary for an operator to lift it by four or five people and carry it from the entrance / exit to a predetermined installation position, which requires a large number of operators. Further, there is a problem that safety is deteriorated due to a large number of workers carrying heavy objects in a place where the foothold is relatively poor.

The present invention has been made in view of the above problems, and an object thereof is to provide a step conveyor device for a passenger conveyor which can easily carry a heavy step without requiring a lot of manpower. It is in.

[0007]

In order to achieve this object, the present invention is provided in a passenger conveyor provided with a moving handrail that runs along the upper ends of balustrades erected on both sides of the steps. In a step conveyor device for a passenger conveyor that transports the vehicle from the entrance / exit to the installation position, the guide rails fitted on the moving handrails, the wheels rolling on these guide rails, and the guide rails It is configured to include a beam body that is bridged over and supported by the wheel, and a lifting means that is provided on the beam body and that suspends the predetermined step.

[0008]

Since the present invention is constructed as described above, first, the guide rails are fitted on the moving handrails, respectively, and the beams are hung on the guide rails so that the wheels come on these guide rails. hand over. Then, a predetermined step is hung by the lifting means provided on the beam and is transported from the entrance / exit to the installation position. In this way, since a predetermined step is carried by the lifting member, it is possible to easily carry a heavy step without requiring a lot of manpower.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a step conveyor device for a passenger conveyor according to the present invention will be described below with reference to the drawings. 1 is a front view showing an embodiment of a step conveyor device for a passenger conveyor according to the present invention, FIG.
1 is a side view of the step transportation device of FIG. 1, and FIG. 3 is a plan view of the step transportation device of FIG.

Generally, a passenger conveyor, for example, an escalator is provided with balustrades 3 standing upright on both sides of a step (not shown) and moving handrails 4 that run along the upper ends of these balustrades 3 as shown in FIG. ing.

As shown in FIGS. 1 to 3, the step carrier according to the present embodiment has guide rails 5 fitted on the moving handrails 4, and these guide rails 5.
Wheels 6 that roll up, beam bodies 7 that are hung on the respective guide rails 5 and are supported by the wheels 6, and a predetermined step provided on the beam bodies 7 via fastening members 8.
For example, a lifting means for suspending the wheelchair steps 9, for example, a chain block 10, a lifting rope 11 connecting the wheelchair steps 9 and the chain block 10, and a connection between the connecting lifting rope 11 and the wheelchair steps 9. And a hanging bracket 12 interposed therebetween.

In this embodiment, when the wheelchair steps 9 are carried in from the entrance / exit, first, FIGS.
As shown in FIG. 5, the guide rails 5 are fitted to the horizontal portions of the left and right hand rails 4, and the beams 7 are bridged so that the wheels 6 are on the guide rails 5. Next, the demarcation portions (not shown) provided on both sides of the wheelchair steps 9 are removed so that the wheelchair steps 9 carried to the entrance / exit can be lifted by a truck (not shown) or the like, and the hanging brackets are used by utilizing the screw holes at the marks Screw 12 together. After that, one end of the lifting rope is attached to the lifting bracket 12, and the chain block 10 is operated to lift the wheelchair step 9 and carry it to a predetermined position. Then, when the wheelchair reaches the predetermined position, the wheelchair steps 9 are hung down in the reverse order of the above procedure, and the series of transportation work is completed.

In the embodiment thus constructed, the predetermined step, that is, the wheelchair step 9 is carried by the chain block 10, so that a heavy step can be easily carried without requiring a lot of manpower. it can.

[0014]

Since the present invention is constructed as described above, it is possible to easily carry a heavy weight step without requiring a lot of manpower, and thereby to efficiently carry the step. In addition, it is possible to prevent a decrease in safety due to a large number of workers carrying heavy objects in a place where the foothold is relatively poor.
