Description

  Embodiments of the present invention relate to a synchronous measuring instrument for a passenger conveyor and a synchronous measuring method thereof.

  In general, in passenger conveyors such as escalators and moving walkways, the steps on which passengers are placed, railings for handrails that are arranged along the driving direction on both sides of the steps, and endless wires that are spanned across the railings for each handrail It has a handrail belt, and the handrail belt and the step are configured to move in synchronization with each other.

  By the way, when using a passenger conveyor, passengers use it by putting their hands on the handrail belt to support the body, but a large force is added to the handrail belt by human or force majeure, or the handrail belt is When slipping, the left and right handrail belts and the steps may not move in synchronization. If such a situation occurs, passengers' attitudes may collapse, leading to an accident.

  Therefore, synchronous measurement of the handrail belt and the step is performed periodically or as necessary.

  By the way, the conventional synchronous measurement does not have a dedicated synchronous measurement tool, and performs synchronous measurement by using a centering down swing used for installation of an escalator or the like.

  As an example of the synchronous measurement method using this centering down swing, two struts are set up on the outside of the handrail belt orthogonal to the escalator running direction, and the swing swing is suspended from the string thread stretched on both struts. A swing is dropped at the center of the step, which is the lowest level before driving, and markings are applied to the center of the step and the handrail belt where the string thread stretched on both supports crosses.

  Thereafter, the escalator is operated and the corresponding step is moved to the vicinity of the highest position. At this time, two struts that are also perpendicular to the escalator running direction are also set up near the top, and the swing is suspended from the string thread stretched on both struts. To do. In this state, it is confirmed whether or not the handrail belt position where the string yarns stretched on both struts intersect and the marking position of the handrail belt are substantially equal, that is, whether the handrail belt and the step are moving in synchronization.

  When the handrail belt and the step are not moving synchronously, necessary measures (for example, applying necessary tension to the handrail belt) are taken.

  However, since the handrail belt and step are measured synchronously using a swing-down swing, the two struts for hanging the swing-down swing are set up, the string is stretched, and the 2 Working efficiency is very bad, such as setting up two columns.

  Also, in the marking of the handrail belt and the step middle part, before and after the escalator operation, that is, the lowest step before the operation and the step near the highest step after the operation are individually set up, There is a problem that the working time becomes long because it is necessary to check the synchronization deviation due to the marking of the handrail belt and the step by lowering the swinging down.

  Furthermore, it has been pointed out that the glass fitted into the railing for handrails may be scratched by the swinging weight of the swinging swing when hanging from the swinging string.

Japanese Patent Laid-Open No. 06-156959

  The problem to be solved by the present invention is to provide a synchronous measuring instrument for a passenger conveyor which can improve the working efficiency of synchronous measurement, can be easily handled, and can realize synchronous measurement safely in a short time, and a synchronous measuring method thereof.

In order to solve the above-mentioned problem, a synchronous measuring instrument for passenger conveyors according to an embodiment has a column part inserted in a cylindrical body standing on a support base so that it can be pulled out, and can be arbitrarily adjusted by adjusting the expansion and contraction of this column part. A support column that is set to the height of the support column, two support arms that are pivotable to the tip of the support column and supported by screw bodies so as to protrude opposite to each other, and the upper end side of the support column is semicircular And an optical memory marker that is attached to the tip of each support arm and that irradiates light on the handrail belts on both sides of the passenger conveyor. And irradiating the handrail belt with light emitted from each optical marker to enable marking for checking the synchronization deviation of the handrail belt .

The block diagram which shows the synchronous measuring tool of the passenger conveyor which concerns on embodiment. The figure explaining a mode that the synchronous measuring instrument of the passenger conveyor which concerns on embodiment is set to the step of an escalator, and marking is performed. The figure which shows an example of the work procedure of the synchronous measurement method of the passenger conveyor which concerns on embodiment.

Hereinafter, embodiments will be described with reference to the drawings.
FIG. 1 is a block diagram showing a synchronous measuring instrument for a passenger conveyor according to an embodiment.

  The synchronous measuring instrument 1 includes a support base 2 such as a box type or a solid block, a support column 3 standing on the support support 2, and two support arms 5 and 5 supported by fixing screws 4 at the end of the support column 3. And markers 6 and 6 attached to the tips of the support arms 5 and 5.

  The column 3 is used as the column 3 with a solid interior. For example, the tip column is inserted so that it can be pulled out into the cylindrical body, and the tip column is pulled out to an arbitrary height and adjusted as necessary. It may be a structure. The fixing screw 4 may be a thumbscrew as well as a commonly used screw.

  As the markers 6 and 6, optical markers that are generally commercially available are used.

FIG. 2 is a diagram showing an example in which the synchronous measuring tool 1 is set on the step of the escalator.
In the figure, 11,... Are steps that are endlessly connected, and 12, 12 are handrails hung on railings for handrails arranged on both sides in the running direction of the steps 11,. 13 is a lower floor board laid on the lower floor of the escalator installed across the upper and lower floors. Similarly, an upper floor board (not shown) is laid on the upper floor of the escalator.

  Accordingly, in FIG. 2A, the synchronous measuring tool 1 is set at the lower step 11 near the lower floor of the escalator, for example, and FIG. 2B is synchronized with the step 11 near the upper floor of the escalator. The state where the measuring tool 1 is set is shown.

  Next, an example of the work procedure of the passenger conveyor synchronous measurement method according to the present embodiment will be described with reference to FIG.

  First, in a state where the escalator is stopped, the optical markers 6 and 6 are fixed to the front ends of the support arms 5 and 5 constituting the synchronous measuring tool 1 by, for example, screwing (S1).

  After that, after setting the synchronous measuring instrument 1 with the optical markers 6 and 6 fixed to the central portion of the upper surface of the lowermost step 11 near the lower floor (S2), the power source of the optical markers 6 and 6 is set. Is turned on (S3).

  Further, after loosening the fixing screw 4, the swing angle of each support arm 5, 5 is adjusted with respect to the horizontal direction, and light emitted from each marker 6, 6 passes through the side surface or belt surface of the handrail belts 12, 12. In this state, the fixing screw 4 is tightened and fixed so that the light emitted from the markers 6 and 6 illuminates the side surfaces of the handrail belts 12 and 12 or the belt surface (S4).

  After projecting the light emitted from the markers 6 and 6 onto the handrail belts 12 and 12 as described above, the marking M is applied to, for example, the side surface of the handrail belts 12 and 12 where the light hits (S5).

  Furthermore, after the power of the markers 6 and 6 is turned off as required (S6), for example, with the synchronous measuring instrument 1 installed on the step 11, or after the synchronous measuring instrument 1 is temporarily removed from the step 11 When the escalator is operated and the corresponding step 11 approaches the upper floor vicinity, the operation is stopped (S7).

  Here, when the power sources of the markers 6 and 6 are turned off, the power sources of the markers 6 and 6 are turned on. When the power of the markers 6 and 6 is turned on, the light emitted from each of the markers 6 and 6 is projected onto the side surfaces of the handrail belts 12 and 12 as in step S5.

  Therefore, the worker measures the distance between each marking M attached to the handrail belts 12 and 12 and the belt portion to which the light emitted from the markers 6 and 6 hits with a scale or the like, and the handrail belt 12 and the step 11 Are synchronized with each other (S8). 2B, the marking M appears in the lower part or the upper part of the belt part irradiated with the light emitted from the markers 6 and 6, so that the handrail belts 12 and 12 are accordingly provided. The state of the tension applied to the belt and indirectly the degree of wear of the handrail belts 12, 12 can also be grasped.

  Therefore, according to the above embodiment, after setting the synchronous measuring tool 1 to the required step 11, the light emitted from the markers 6 and 6 is projected onto the handrail belt 12 for marking. Thus, there is no need for operations such as erecting the struts, tying the string, and hanging the swinging swing from the string to the optimum position, and the operation of marking on the handrail belt 12 can be performed very efficiently.

  In addition, since the synchronization measuring tool 1 is simply placed at the center of the lowest step before driving and the step near the highest position after driving, the synchronization deviation due to the marking of the handrail belt and the step is confirmed in a short time. it can.

  Further, it is possible to reduce the risk of damaging the glass fitted into the railing for handrails due to the swinging weight of the lower swing as in the prior art.
