Abstract

(57) [Summary] [Purpose] Not only the front and back of the handrail,
Providing a handrail inspection device for passenger conveyors that can easily detect abnormalities in the handrail layer. [Structure] A frame body 2 set so as to sandwich a handrail 1, rollers 3 and 4 contacting the handrail 1 from above and below by the frame body 2, and elastic bodies 5 and 6 elastically pressing the rollers 3 and 4, and a roller. The recording device 10 electrically takes out the displacements of 3 and 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail inspection device for passenger conveyors.

[0002]

2. Description of the Related Art A conventional device of this type is disclosed in Japanese Patent Laid-Open No.
As described in Japanese Patent Publication No. 95096, at the time of inspecting the handrail, a photoelectric sensor facing the back surface of the handrail and separated by a predetermined distance, an optical fiber connected to the photoelectric sensor, and an optical fiber And an output unit that detects the reflected light from the back surface of the handrail and generates an output signal according to the magnitude of the reflected light with respect to a preset value, and a display device that displays the output signal presence / absence state of the amplifier unit. I can give you something.

[0003]

By the way, the handrail generally comprises a surface layer made of a polymer material, a steel body embedded in the surface layer to resist tension acting on the handrail, and a back surface of the handrail. It consists of a canvas layer,
Abnormalities in the handrail are manifested as cracks and stains generated on the polymer material forming the surface layer, cutting of the steel body, tearing of the canvas layer, and peeling between these layers. Therefore, there is a problem that the inspection device for only the back surface as in the above-mentioned known example is not sufficient for inspection of the handrail.

An object of the present invention is to provide a handrail inspection device for a passenger conveyor that solves the above problems.

[0005]

In order to achieve the above object, the present invention is directed to a plurality of steps connected endlessly and traveling between two entrances and exits, and balustrades erected on both sides of these steps. And a handrail inspection of a passenger conveyor, a part of which is supported by the balustrade, and a handrail that travels between both entrances and exits at substantially the same speed as the step and a drive device for traveling the step and the handrail In the device, a frame body inserted from the side of the handrail so as to surround the handrail, and supported by the frame body so as to be capable of contacting the handrail from the front and back sides, and at least one of the front and back sides. Is provided with rollers that can come into contact with each other via an elastic body, and the change in the gap between these rollers is electrically measured.

[0006]

With the above configuration, when some abnormality occurs in the handrail, the gap between the upper and lower rollers that sandwich the handrail changes. Therefore, by electrically picking this up and recording it, The presence or absence of abnormality can be prepared and examined in detail.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described.

FIG. 1 is a schematic view of this device attached to an escalator, FIG. 2 is an enlarged view of a main part, and FIG. 3 is a side view of FIG.

In the figure, 1 is a handrail, 2 is a frame body inserted from the side of the handrail 1 so as to surround the handrail 1, 3 is a roller that abuts on the surface of the handrail 1, and 4 is a handrail 1. A roller abutting the back surface of the roller applies pressure to the handrail 1 by elastic bodies 5 and 6, 7 and 8 are potentiometers for measuring the displacement of rollers 3 and 4, respectively, 9 is a wiring, and 10 is a record including a comparator and the like. Reference numeral 11 is a frame of the escalator, and 12 is a bolt for fixing the frame body 2 to the frame 11.

Due to the above-mentioned structure, at the time of inspection, the elastic body 5, 6 is distorted inside the balustrade (not shown) so that the frame 2 is surrounded by the rollers 3, 4 so as to surround the handrail 1 from the front and back. After inserting and setting, rotating the escalator and inputting the displacement of the upper and lower rollers 3 and 4 to the recorder 10, the result is brought back to the site or office for consideration.

[0011]

According to the present invention, it is possible to easily and in detail investigate not only the front and back surfaces of the handrail but also the abnormality occurring in the layer.

[Brief description of drawings]

FIG. 1 is a schematic view in which a handrail inspection device for a passenger conveyor of the present invention is attached to an escalator.

FIG. 2 is an enlarged view of a main part of FIG.

FIG. 3 is a side view of FIG.

Claims (1)

[Claims]
1. A step in which a plurality of endless vehicles are connected to each other to run between two entrances and exits, a balustrade standing upright on both sides of these steps, and a part of the balustrade supported by the balustrades. In a handrail inspection device for a passenger conveyor, which includes a handrail that travels at approximately the same speed as the step and a drive device that runs the step and the handrail, the handrail is surrounded from the side of the handrail. A frame body inserted in such a manner, and a roller supported by the frame body so as to be able to contact the handrail from the front and back sides, respectively, and at least one of the front and back sides can be contacted via an elastic body. A handrail inspection device for a passenger conveyor, characterized by electrically measuring a gap change between these rollers.
