BEST MODE FOR CARRYING OUT THE INVENTION

DESCRIPTION OF EXEMPLARY EMBODIMENTS First Embodiment Hereinafter, an embodiment of the invention will be described with reference to the drawings.

  FIG. 1 to FIG. 4 and FIG. 9 to FIG. 11 are diagrams showing a driving force measuring device for a moving handrail of an escalator according to an embodiment.

  First, the entire escalator will be described with reference to FIGS. 10 and 11. As shown in FIGS. 10 and 11, the escalator 21 has a moving handrail 6 that circulates and moves. At the time of the inspection work, the worker P stands on the landing 21A where the escalator 21 is installed, and measures the driving force of the moving handrail 6 with the driving force measuring device 20 of the moving handrail.

  As shown in FIGS. 1 to 4, the moving handrail driving force measuring device 20 is mounted on the moving handrail 6 and fixed to the moving handrail 6. The connected holding tool 5 and the driving force measuring device 4 that is mounted in the holding tool 5 and measures the driving force of the moving handrail 6 to which the fixing tool 1A is mounted are provided.

  Among these, the fixture 1A has a steel suction cup box 7 to which the operation lever 2 is attached and a rubber suction cup 1 attached to the lower surface of the suction cup box 7, and operates the operation lever 2 of the suction cup box 7. Thus, the suction cup 1 can be switched between the operation mode and the non-operation mode.

  Further, a steel handle 8 is attached to the suction cup box 7, and the holder 5 is connected to the handle 8 of the suction cup box 7 via a steel cannabiner 3.

  As shown in FIG. 1 to FIG. 4, the holder 5 is made of steel, has a box shape with an open top, and a pair of steel holders extending outwardly on both side surfaces of the holder 5. A bar 5a is provided so as to protrude. As will be described later, the worker P can hold the pair of holding bars 5a to hold the holding tool 5.

  Next, the operation of the present embodiment having such a configuration will be described with reference to the flowchart shown in FIG.

  First, as shown in FIGS. 1 and 2, at the start of the inspection work, a suction cup box 7 having a suction cup 1 attached to the lower surface is arranged on the moving handrail 6. Next, the operation lever 2 is operated, and the suction cup 1 is set to the operation mode. At this time, the contact surface between the suction cup 1 and the moving handrail 6 is in a vacuum state, and the suction box 7 is fixed on the moving handrail 6 by the suction cup 1.

  Next, as shown in FIG. 3, the driving force measuring device 4 having the measuring bar 4 a is attached in the holder 5. At this time, the measurement bar 4 a passes through the opening 5 b of the holder 5. Thereafter, as shown in FIG. 4, the cannabiner 3 is attached to the measurement bar 4 a of the driving force measuring device 4 that protrudes outward from the opening 5 b of the holder 5.

  Next, the cannabina 3 is hooked on the handle 8 of the suction cup box 7.

  Next, the operator P grips the pair of holding bars 5 a and 5 a of the holder 5 and pulls the holder 5. As a result, the suction cup box 7 fixed to the moving handrail 6 via the suction cup 1 is pulled by the holder 5, and the driving force of the moving handrail 6 is measured by the driving force measuring device 4. It is displayed on the measuring device 4.

  The operator P confirms the driving force of the moving handrail 6 displayed on the driving force measuring device 4. When the measured driving force deviates from the specified value, the operator P adjusts the driving mechanism (not shown) of the moving handrail 6 so that the driving force of the moving handrail 6 falls within the specified value. Thereafter, the worker P repeats the same operation as described above and measures the driving force of the moving handrail 6 again.

  When the measured driving force is within the specified value, the operation lever 2 is operated to place the suction cup 1 in the non-operation mode. At this time, the vacuum state is released at the contact surface between the suction cup 1 and the moving handrail 6, and the suction box 7 and the suction cup 1 are removed from the moving handrail 6.

  In this way, the inspection work can be completed.

  As described above, according to the present embodiment, the suction cup box 7 having the suction cup 1 can be easily and reliably fixed to the moving handrail 6, and thereby the driving force measuring device 4 connected to the suction cup box 7. Thus, the driving force of the moving handrail can be reliably measured.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment shown in FIG. 1 to FIG. 4 and FIG. 9 to FIG. 11, the sucker box 7 to which the operating lever 2 is attached is the fixing tool 1A fixed to the moving handrail 6, However, the present invention is not limited to this, and the fixture 1A includes a steel handrail clamping jig 9 that covers the movable handrail 6 and sandwiches the movable handrail 6. You may do it.

  In the second embodiment shown in FIG. 5 to FIG. 8, the same parts as those in the first embodiment shown in FIG. 1 to FIG. 4 and FIG. 9 to FIG. To do.

  5 to 8, the handrail clamping jig 9 is connected to a holder 5 having a built-in driving force measuring device 4 via a connecting tool (not shown). A cannabiner or the like is conceivable as a connector for connecting the pinching jig 9 (see FIGS. 1 to 4).

  As shown in FIGS. 5 to 8, the movable handrail 6 is generally movably mounted on a handrail rail 10 having a T-shaped cross section, and the movable handrail 6 corresponds to the handrail rail 10. It has a U-shaped cross-sectional shape.

  In this case, the handrail clamping jig 9 includes a pair of jig portions 9a and 9a. Each jig portion 9a and 9a surrounds the moving handrail 6 and has a cylindrical portion 18 having a rubber rubber 18b attached to the inner surface thereof, and a cylinder. And a curved flange portion 19 provided above the portion 18.

  Next, the operation of the present embodiment having such a configuration will be described. At the start of the work inspection, the jig portions 9a, 9a of the handrail clamping jig 9 are mounted on the outside of the movable handrail 6, and bolts are inserted into the openings 19a provided in the flange portions 19 of the jig portions 9a, 9a. 11a and nut 11b are attached. Then, by tightening the bolt 11a and the nut 11b, the curved flange portions 19 and 19 of the jig portions 9a and 9a are flattened. Along with this, the tip 18a of the cylindrical portion 18 of each jig portion 9a, 9a expands the lower end 6a of the movable handrail 6 outward in the lateral direction, and opens the movable handrail 6. At the same time, the handrail clamping jig 9 can firmly hold the moving handrail 6.

  Next, the holding tool 5 in which the driving force measuring device 4 is incorporated is connected to the handrail clamping jig 9 via the connecting tool.

  Thereafter, simultaneously with the first embodiment, the worker P holds the pair of holding bars 5a, 5a of the holder 5 and pulls the holder 5. As a result, the handrail clamping jig 9 fixed to the moving handrail 6 is pulled by the holder 5, and the driving force of the moving handrail 6 is measured by the driving force measuring device 4. Is displayed.

  As described above, according to the present embodiment, the moving handrail 6 can be firmly held by the handrail holding jig 9. At this time, since the handrail 6 can be opened by the handrail clamping jig 9, only the handrail 6 can be pulled without applying a load to the handrail rail 10 from the handrail 6. The driving force of sliding can be measured more reliably.
