Abstract

PROBLEM TO BE SOLVED: To provide a traveling handrail traction tool for a passenger conveyor capable of being mounted on a traveling handrail easily and securely. SOLUTION: A clamping piece 15 is arranged in a condition in which holding parts 16 are pressed against side faces on both sides in the direction of width of a traveling handrail 7, respectively, and a fitting piece 18 is fitted in the clamping piece 15. The clamping piece 15 is pushed into the fitting piece 18 due to the traction of the fitting piece 18, and the clamping piece 15 nips and presses the traveling handrail 7 due to the wedge action of a wedge face 17 of the clamping piece 15 and a wedge inclined face 21 of the fitting piece 18 to grip it firmly. Consequently, a slide does not occur between a traction tool consisting of the clamping piece 15 and the fitting piece 18 and the traveling handrail 7, the judgement for judging whether a drive condition of the traveling handrail 7 is proper or not is made accurate, and the traction tool can be mounted on the traveling handrail 7 easily to improve the efficiency of travel resistance measuring work.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 1 to 6 are views showing an example of an embodiment of the present invention. FIG. 1 is a plan view showing a mounting state of a traction tool of a moving handrail of a passenger conveyor, and a plan view of a pincer shown in FIG. 1 in FIG. FIG. 3 is an enlarged sectional view taken along line AA of FIG. 4 is a perspective view showing the fitting state of the presser and the fitting of FIG. 1, FIG. 5 is a perspective view showing the presser of FIG. 4, and FIG.
It is a perspective view which shows the fitting. Except for FIGS. 1 to 6, a passenger conveyor is configured in the same manner as in the above-described 7. In the figure, reference numeral 7 denotes a moving handrail which is endless and circulates from the upper side of the balustrade 6 into the main frame 1.

Numerals 15 denote pressurizers made of a viscoelastic material such as rubber, which are disposed on both sides in the width direction of the moving handrail 7 and retreat inside, that is, in grooves corresponding to the side faces in the width direction of the moving handrail 7. A formed holding portion 16 is provided, and the moving handrail 7 is provided.
On the outer surface along the side surface in the width direction of the wedge surface 1, one longitudinal end of the presser 15 is closer to the width direction of the moving handrail 7 than the other end.
7 are configured. That is, one end of the length of the pinching element 15 shown in FIG. ₂ is formed to have a width l ₁ , and the other end is formed to have a width l ₂ wider than the width l ₁ .

Numeral 18 denotes a metal fitting, which has a cross-sectional groove and has an opening 20 formed on the other side opposite to the bottom surface 19, the opening 20 being narrower than both side walls in the cross-sectional groove. A wedge inclined surface 21 corresponding to the wedge surface 17 is formed on the inner surface of both side walls of the groove having a cross section facing the wedge surface 17 of the indenter 15 so as to correspond to the wedge surface 17. 2 is provided with a connecting portion 22 formed of a through hole at a position corresponding to the wide other end side shown in FIG. Reference numeral 23 denotes a handrail rail provided along the length of the upper edge of the balustrade 6 and to which the moving handrail 7 is movably fitted, for guiding the movement of the moving handrail 7.

Using the moving device for the handrail of the passenger conveyor constructed as described above, the movement resistance of the moving handrail of the passenger conveyor is measured as described below. That is, the clamper 15 is arranged in a state where the clamping portions 16 are pressed against both side surfaces in the width direction of the moving handrail 7 with the passenger conveyor stopped. Next, the opening 20 of the fitting 18 is fitted to the moving handrail 7 from the right side of the presser 15 in FIG. 1, and the wide portion of the wedge slope 21 of the fitter 18 is inserted into the width l _{1 of the} presser 15 shown in FIG. Insert from the side end and fit.

Then, the measuring tool 13 in FIG. 7 described above is connected to the connecting portion 22 of the fitting 18, and the worker 14 interposes the end of the pinching element 15 on the width l ₁ side shown in FIG. The fitting 18 is pulled in the direction of the part, that is, in the direction of arrow B shown in FIG. As a result, the pincer 15 is pushed into the fitting 18, and the pincer 15 presses the moving handrail 7 by the wedge action of the wedge surface 16 and the wedge slope 21, so that the moving handrail 7 is firmly gripped.

Then, the moving handrail 7 is towed through a towing device comprising the presser 15 and the fitting 18, and the driving mechanism 8 is driven.
In the state where the moving handrail 7 is stopped, the appropriateness of the driving state of the moving handrail 7 is determined based on the measured value when the moving handrail 7 moves by sliding. By such a determination, the driving force of the moving handrail 7 generated by the driving mechanism 8 is approximately inspected. The essential driving force of the moving handrail 7 is the pulling force of the measuring tool 13 when the driven moving handrail 7 is stopped by being braked, which is the moving resistance of the moving handrail 7.

In the work for measuring the movement resistance of the moving handrail 7, no slippage occurs between the traction tool and the moving handrail 7, and the suitability of the driving state of the moving handrail 7 can be accurately determined. . In addition, the towing tool can be easily attached to the moving handrail 7, and the efficiency of the work of measuring the moving resistance of the moving handrail 7 can be improved.

[0017]

As described above, according to the present invention, the holding portions are formed on the inner surface of the moving handrail, which are disposed on both sides of the widthwise side surface of the moving handrail, and one end of the longer length of the moving handrail is larger than the other end. An indenter having a wedge surface approaching the widthwise side surface formed on the outer surface, and a wedge slope corresponding to the wedge surface of the nubber formed on the inner surface. And a fitting that is pulled in the direction of the other end of the indenter.

Thus, the clamps are arranged in such a manner that the clamping portions are pressed against the side surfaces on both sides in the width direction of the moving handrail, and the fittings are fitted to the clamps. Then, when the fitting is pulled, the pincer is pushed into the fitting, and the pincer presses the moving handrail by the wedge action of the wedge surface and the wedge slope to firmly grip the moving handrail. Therefore, no slippage occurs between the moving handrail and the traction tool including the pincer and the fitting element, and there is an effect of accurately determining whether the driving state of the moving handrail is appropriate. In addition, the towing tool can be easily attached to the moving handrail, which has the effect of improving the efficiency of the work of measuring the moving resistance of the moving handrail.
