Description

  The present invention relates to a measuring device for measuring displacement at various locations on a passenger conveyor and a displacement measuring method using the measuring device.

  In recent years, passenger conveyors (this “passenger conveyor” includes, for example, “escalators” and “moving sidewalks” in various places. In the following, “escalators” will be described as examples. “Conveyors” are referred to as “escalators”). Once the escalator is installed, test verification on the balustrade and skirt panel strength and measurement of the operating force of the skirt panel switch provided inside the skirt panel will be performed. For example, it is determined whether or not these values match values determined by a passenger conveyor installation company.

  Specifically, in these test verifications and operating force measurements, when a predetermined load is applied to the balustrade or skirt panel, the amount of spread of the balustrade or skirt panel that is spread outward falls within a predetermined range. Or by measuring whether the skirt panel switch is turned on at a predetermined load when a load is applied to the skirt panel.

As a method of applying a load, there is a method of applying a load to a railing or the like manually. Further, as a device for applying a load to a railing or a skirt panel instead of human power, a skirt guard switch operating force measuring device for a passenger conveyor described in Patent Document 1 is disclosed. This measuring apparatus includes a measuring tool whose one end is in contact with the step side of the skirt guard, and a pressing force applying means whose other is in contact with the other end of the measuring tool. The pressing force applying means includes a pressing element that contacts the step side of the skirt guard and includes a screw rod, and a pressing body that is screwed with the screw rod and moves in accordance with the rotation to press the measuring tool. Consists of.

  However, the method of applying a load by human power is difficult to obtain as objective data regarding numerical values such as the applied load and the amount of expansion of the measurement object that is expanded by the applied load. Negative effects such as lack of sex are pointed out.

  Moreover, according to the invention disclosed in Patent Document 1, the balustrade and the like are gradually spread by rotating the pressing element (screw rod), and the position of the pressing element is changed to the measurement position along with the rotation. It is possible that it will deviate from. Furthermore, when an elastic body such as a spring is used for the measuring tool, every time test verification and operating force are measured, for example, a load applied using a constant value such as a spring constant of the elastic body is calculated. It will be. This constant value is based on the premise that the state of the elastic body has not changed, and the value that should be constant when measured may change depending on the state of the elastic body. . If this happens, a reliable value cannot be obtained no matter how much measurement is performed, and the uncertainty of the measurement may result in a lack of credibility of the measurement value.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a measuring device for measuring displacement at various locations on a passenger conveyor by a simple configuration and method, and a displacement measuring method using the measuring device. Is to provide.

A step of attaching the tip part in contact with each other, a step of measuring and confirming whether the measuring device is properly attached at the measurement position, a displacement measuring means using the position at the attachment position of the measuring device as the reference position as a reference position, and A step of adjusting the load measuring means, a step of extending the movable part of the measuring device by an actuator and applying a load to the measuring object, and a step of acquiring the displacement of the measuring object when the load reaches a prescribed value With.

  ADVANTAGE OF THE INVENTION According to this invention, the displacement measuring method using this measuring apparatus and the measuring apparatus which measures the displacement in a passenger conveyor place with a simple structure and method can be provided.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  A measuring apparatus according to an embodiment of the present invention and a displacement measuring method using the measuring apparatus will be described with reference to FIGS.

  FIG. 1 is an overall view showing a measuring apparatus 1 according to an embodiment of the present invention. The measuring apparatus 1 includes a cylindrical main body 2 having an actuator 2a (not shown) therein, a movable portion 3 provided at one end of the main body 2 and made extendable by the actuator 2a, and attached to the movable portion 3. Displacement measuring means 4 that measures the expansion and contraction of the movable part, a load measuring means 5 that is provided at the other end of the main body part 2 and that measures the load applied to the measurement object as the movable part 3 expands and contracts, and the actuator 2a are controlled. And a control means 6 for performing.

  The main body 2 is formed in a cylindrical shape. However, the cylindrical shape may be any shape such as a cylindrical shape or a rectangular column shape as long as it can accommodate an actuator (not shown in FIG. 1) 2a for driving the movable portion 3. It doesn't matter.

  The actuator 2a housed in the main body 2 drives the movable part 3 used when a load is applied to a railing or skirt panel (hereinafter collectively referred to as “railing etc.”) of a passenger conveyor to be measured. Is for. The actuator 2 a expands and contracts the movable part 3 in the long side direction of the main body part 2. The method for driving the movable portion 3 may be hydraulic, pneumatic, mechanical, electric, or manual. In the embodiment of the present invention, the movable part 3 is electrically driven based on an instruction from the control means 6 described later.

  The movable part 3 is driven by the actuator 2a of the main body part 2 as described above, and applies a load to the balustrade or the like to be measured. For the position where the load is applied, the tip of the movable part 3 directly contacts the balustrade or the like. Further, a separate pressing portion 3a may be provided at the tip portion. A thin flat plate is attached to the movable portion 3 shown in FIG. 1 as the pressing portion 3a. By bringing the pressing portion 3a into contact with the measurement position vertically, the load from the movable portion 3 is reliably applied to the measurement object without waste.

  In the embodiment of the present invention, as described above, a thin flat plate is attached to the distal end portion of the movable portion 3 as the pressing portion 3a. However, the shape of the pressing portion 3a is adapted to the measurement object. Any shape, such as a concave member instead of a flat plate, can be used as long as the load is reliably transmitted to the measurement target.

  The main body 2 and the movable part 3 are further provided with a displacement measuring means 4. The displacement measuring means 4 has a displacement detecting piece 4a fixed at a predetermined position of the movable portion 3 and a distal end portion that is fixed to the main body 2 and that can be expanded and contracted, always in contact with the displacement detecting piece 4a. 3 and a measuring unit 4b for measuring the displacement of 3.

  The displacement detection piece 4a is, for example, a flat plate fixed to the movable part 3, and moves as the movable part 3 is driven via the actuator 2a. The measuring part 4b is configured such that its tip always comes into contact with the displacement detection piece 4a. Therefore, as the movable part 3 (displacement detection piece 4a) moves, the tip part of the measuring part 4b also follows and moves. The displacement of the movable part 3 can be grasped by measuring the moving distance of the tip part. The measurement unit 4b is connected to the display unit 7 described later, and causes the display unit 7 to display the displacement of the movable unit 3 measured by the measurement unit 4b.

  A load measuring means 5 is provided on the opposite side of the movable portion 3 with the main body portion 2 interposed therebetween. This load measuring means 5 is for measuring the load applied to the measurement object by driving the movable part 3. As with the movable part 3, a pressing part 5 a may be provided at the tip of the load measuring means 5. The pressing portion 5a comes into contact with a balustrade or the like at a position facing the balustrade or the like with which the pressing portion 3a of the movable portion 3 contacts. In addition, about the shape of the pressing part 5a, as long as it is a shape which can measure reliably the load added to the measuring object as mentioned above, what kind of shape may be sufficient as it.

  The actuator 2a is controlled by the control means 6. The control means 6 is provided with a power ON / OFF switch 6a and an expansion / contraction switch 6b for expanding / contracting the movable portion 3 as shown in FIG.

  A display means 7 is further connected to the measuring device 1. This display means 7 displays the value of the displacement of the movable part 3 and the value of the applied load when the movable part 3 is driven and a load is applied to the measurement object. In the embodiment of the present invention, the control means 6 and the display means 7 have been described as separate means. However, they may be connected to the measuring apparatus 1 in an integrated manner.

  Further, a joint 8 that can be added according to the measurement object is detachably provided between the main body 2 and the load measuring means 5. The joint 8 can be omitted, or even if it is used, it is suitable for the length from the pressing part 3a of the movable part 3 to be measured to the pressing part 5a of the load measuring means 5 according to the length. 8 can be attached to the measuring apparatus 1. Therefore, a plurality of joints 8 having different lengths are prepared in advance. FIG. 1 shows a state where the joint 8 is attached to the measuring apparatus 1.

  Next, a displacement measuring method for measuring the displacement at various portions of the passenger conveyor using the measuring device 1 will be described below using the flowchart of FIG. 2 and FIG.

  FIG. 2 is a flowchart showing the flow of the measuring method using the measuring apparatus 1. First, the measurement target is specified. Here, we take into account the measurement of the balustrade and skirt panel strength and the operating force of the skirt panel switch. In the case of the balustrade strength measurement, the measuring device 1 is installed at a position as shown in FIG.

  FIG. 3 is a diagram showing a state in which the balustrade strength is measured using the measuring device 1. In the measuring apparatus 1, the pressing part 3 a of the movable part 3 and the pressing part 5 a of the load measuring means 5 are in direct contact with the balustrade 21, and the pressing part 3 a comes into contact when the movable part 3 extends. A load is applied to 21. The control means 6 and the display means 7 of the measuring apparatus 1 are placed on the step 22. Skirt panels 23 are provided on both sides of the step 22 so as to face each other.

  On the other hand, in the case of measuring the strength of the skirt panel or the operating force of the skirt panel switch, the measuring device 1 is provided at a position where the pressing portion 3a of the movable portion 3 and the pressing portion 5a of the load measuring means 5 face each other. It installs in the position which contact | abuts the skirt panel 23 which has been shown (not shown).

  When the measurement object is determined, the joint 8 is selected and attached in accordance with the measurement location where the measurement apparatus 1 is installed (ST1). For example, in the passenger conveyor, the length between both balustrades differs depending on whether one rides on one step or two rides. A joint 8 that can appropriately cope with this difference in length is selected.

  After attaching the joint 8 to the measuring device 1 (or without attaching it), the pressing portion 3a of the movable portion 3 and the pressing portion of the load measuring means 5 at a predetermined position (measurement position) where the measuring device 1 is applied. 5a is applied (ST2). At this time, the movable part 3 is extended to such an extent that the pressed measurement object is not deformed. In this state, the measuring apparatus 1 can stay at the measurement position without falling. In this state, the level of the measuring apparatus 1 is measured (ST3).

  For the measurement of the level, a level 9 as shown in FIG. 3 is used. In the embodiment of the present invention, the level device 9 is not included as a component of the measuring device 1, but is separately provided. However, it can be incorporated in the measuring device 1 in advance.

  After confirming that the measuring device 1 is level with respect to the measurement object using the level 9, it is next confirmed whether the pressing portion 3 a and the pressing portion 5 a are in contact with the measurement position without any gap (ST 4). ). For example, as shown in FIG. 1 or FIG. 3, when a flat plate is used for the pressing part 3 a and the pressing part 5 a, both pressing parts are brought into close contact with the balustrade 21 as long as the measurement position of the balustrade 21 is not curved. Is possible. If both pressing parts can be brought into close contact with the balustrade 21, it becomes clear that the measuring apparatus 1 is installed at a position perpendicular to the balustrade.

  This step (ST3 and ST4) is a so-called “centering” step. Thus, by placing the measuring apparatus 1 horizontally and at right angles to the measurement object, a load is appropriately applied to the measurement object. And more accurate displacement can be measured. In addition, by using a simple instrument called the level 9 or simply checking the gap between the pressing portion and the measurement position, the thread with a weight attached to the tip as in the past is hung from the measurement device. There is no need for centering, and the measuring device 1 can be easily installed at the measurement position.

  As described above, according to the steps so far, the measuring apparatus 1 does not displace the measurement object and does not fall and remains at the measurement position. Therefore, the displacement measuring means 4 is adjusted using this state as a reference position (ST5). For example, the reference position is adjusted to be 0 point. Further, the load measuring means 5 is also adjusted so that this reference position is set to 0 (ST6). By adjusting the displacement measuring means 4 and the load measuring means 5 in this way, the displacement and the applied load can be clearly recognized when the movable part 3 is driven and a load is applied.

  Then, the actuator 2a is extended to drive the movable part 3, and a load is applied to the measurement target (ST7). The load to be applied is defined in advance by the installer of the passenger conveyor and the load is applied until the specified value is reached (ST8). The applied load is measured by the load measuring means 5 and displayed on the display means 7. Further, the displacement measuring means 4 measures the displacement caused by applying a load to the measuring object on the display means 7.

  When a specified load is applied (YES in ST8), the displacement at that load is read from the display means 7 and recorded (ST9). This record is a basis for determining whether or not the displacement in the measurement object shows an appropriate value. Thereafter, the actuator 2a is moved to shrink the movable part 3 back (ST10).

  FIG. 3 shows a state where the measuring device 1 is installed on the balustrade 21 to be measured and the movable part 3 is extended. As shown in FIG. 3, both of the pair of balustrades 21 and 21 are inclined outward from a vertical position. In this state, the displacement D from the vertical position of the balustrade is measured by the displacement measuring means 4.

  In general, the displacement occurs equally in the measurement object that is opposed. That is, the amount of displacement that appears at the measurement position where the movable part 3 abuts is equal to the amount of displacement that appears at the measurement position where the load measuring means 5 abuts. Therefore, the value of the displacement D measured by the displacement measuring means 4 and displayed on the display means 7 is a value twice as large as the actually measured displacement amount. Therefore, in the display means 7, the actually measured displacement amount may be halved in advance, or the actually measured displacement amount may be displayed as it is.

  A measuring apparatus and a measuring apparatus that can measure displacement at various locations on a passenger conveyor by a simple structure and method by installing and measuring the measuring apparatus 1 adopting such a configuration on a balustrade or the like to be measured. The displacement measuring method using can be provided.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine the component covering different embodiment suitably.

  For example, until now, the measuring device has stretched the movable part with respect to the measuring position to maintain the state in which the measuring object is not displaced with respect to the measuring object at the opposite position, thereby dropping the measuring device. However, if it is difficult to hold the measurement object at the measurement position without displacing the measurement object, the measurement apparatus 1 is placed on a table and measured. Of course.

1 is an overall view showing a measuring apparatus according to an embodiment of the present invention. It is a flowchart which shows the flow of the measuring method using the measuring apparatus which concerns on embodiment of this invention. It is explanatory drawing which shows the state which installed the measuring apparatus in the balustrade which is a measuring object in embodiment of this invention, and extended the movable part.
